ObjectiveWe analyzed and compared the clinical characteristics of benign and malignant parotid gland tumors.Patients and methodsA total of 992 patients who underwent surgical treatment for parotid gland tumors from January 2010 to December 2020 were included in this study. This study population was subdivided into benign (n = 812, 81.9 %) and malignant parotid gland tumors (n = 180, 18.1 %).ResultsPleomorphic adenoma is the most common benign tumor and mucoepidermoid carcinoma is the most common malignant tumor. The patients with malignant parotid gland tumors were older than the patients with benign lesions. The duration of symptoms was longer in patients with benign parotid gland tumors compared to those with malignant lesions. The size of the malignant tumors was larger than that of the benign lesions. Preoperative fine-needle aspiration cytology had a diagnostic sensitivity of 50.3 %, diagnostic specificity of 98.7 %, a positive predictive value of 89.5 %, a negative predictive value of 89.9 %, and accuracy of 89.9 % for diagnosing malignant parotid gland tumors. For benign parotid gland tumors, superficial parotidectomy was most frequently performed, and for malignant parotid gland tumors, total parotidectomy was most frequently performed. Facial palsy was observed in 19.4 % of the patients with malignant parotid gland tumors compared to 5.4 % of those with benign tumors.ConclusionThe clinical features of benign and malignant parotid gland tumors showed differences in age, symptoms, duration of symptoms, size and site of the parotid tumors, surgical procedures, and postoperative facial nerve palsy. 相似文献

ObjectiveTo evaluate surgical approaches and outcomes associated with accessory parotid gland neoplasms.Data sourcesMEDLINE, SCOPUS, and the Cochrane Central Register of Controlled Trials.Review methodsA systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was performed. Studies were included if they reported surgical management and outcomes of patients with accessory parotid gland neoplasms.ResultsAfter screening 3532 records, 15 studies were included with a total of 187 patients. Benign tumors consisted of 61.5% of cases. External open, transoral, and preauricular endoscopic approaches were used for 82.3%, 11.3%, and 6.5% of cases, respectively. Accessory lobe resection alone, concurrent with partial parotidectomy, and concurrent with total parotidectomy were used in 54.8%, 43.0%, and 2.2% of cases, respectively. Complication rates were similar between histology groups (7.8% benign vs. 8.3% malignant, p = 0.82). Accessory lobe resection with concurrent partial parotidectomy had the lowest overall complication rate (6.3%). Resections limited to the accessory lobe were found to have an overall complication rate of 8.7%.ConclusionThe results offer an overview of the surgical management and complications for accessory parotid gland tumors. Overall surgical complication rates found in these case series may be lower for management of accessory gland tumors than rates available in the literature for tumors within the main parotid gland. 相似文献

PurposeMajor salivary gland tumors constitute almost 3% of head and neck tumors. Tumors located exclusively in the deep lobe are not common and 20% of parotid gland tumors originate from deep lobe under the branches of the facial nerve. Accuracy of fine needle aspiration biopsy (FNAB) procedure in salivary gland tumors have been studied extensively, however there isn't any data regarding usefulness of FNAB in tumors located exclusively in deep lobe of parotid gland. In this study we aimed to assess the use of FNAB in deep lobe parotid tumors.Materials and methodsWe retrospectively analyzed 51 patients with deep lobe parotid tumors who underwent surgery in our clinic between January 2013–December 2018. Characteristics of patients were recorded. Preoperative FNAB results and postoperative final histopathologic diagnosis were compared. Statistical analysis was performed using SPSS 24.0 was used for statistical analysis.ResultsThe number of patients that met the inclusion criteria was 51. The mean age of patients were 49.2(14–86). In 40 (78.4) of the patients, tumor was reported as benign and in 11 (21.6) patients FNAB diagnosis was suspicious for malignancy, malignant or non-diagnostic. In final histopathologic diagnosis, 42 of the tumors were benign and 9 were malignant. The most common benign tumor type was pleomorphic adenoma which constitutes 27 of the cases (52.9%). Regarding detection of malignant disease, the sensitivity of FNAB was 90.4%, specificity was 77.7%, positive predictive value was 95%, negative predictive value was 63.6%. There was a substantial agreement between FNAB and final histopathologic diagnosis(kappa = 0,628).ConclusionsFNAB is a safe and reliable tool to evaluate deep lobe parotid tumors. It is an important part of preoperative surgical planning and can help the surgeon in patient counseling. FNAB with ultrasound guidance is recommended for deep lobe tumors. 相似文献

The aim of this study is to investigate the clinical and pathological characteristics of basal cell adenoma (BCA) and to compare
the diagnosis/treatment of BCA with those of Warthin’s tumor (WT) and pleomorphic adenoma (PA). Among 192 patients with benign
tumors of the parotid gland who underwent surgery, 9 had BCA. All of these tumors showed a benign pattern on computed tomography
and magnetic resonance imaging. The accuracy of fine needle aspiration biopsy (FNAB) for diagnosis of BCA was slightly lower
than for PA and WT. Most PA and BCA lesions developed in the upper part of the parotid gland. Considering the gender difference,
tumor site, and age, it is necessary to differentiate BCA from PA rather than from WT. There were no significant differences
in the duration of surgery, the blood loss, and the incidence of transient facial paralysis between surgical resection of
BCA and surgery for PA or WT. BCA is the third most common of the benign parotid tumors, following WT and PA, although its
incidence is low. When PA and WT are ruled out by FNAB after a tentative diagnosis of benign tumor has been based on imaging
findings, BCA should be considered. 相似文献

Objective
The current study presents our experience with accessory parotid gland masses and reviews the literature on accessory parotid tumor incidence and surgical management. Based on our results, we advocate a standard parotidectomy approach with routine facial nerve dissection at the time of excision.Study Design
We performed a retrospective chart review and comprehensive literature review on incidence of accessory parotid gland neoplasms.Methods
A retrospective chart review of all patients with mid-cheek masses treated by the senior author was conducted from January 2003 to January 2009. The tumor size at presentation, FNA biopsy, pathologic diagnosis, and surgical treatment were recorded for 13 patients.Results
In the case series, 54% of lesions were benign (n = 7) and 46% were malignant (n = 6) including benign pathologies of 4 pleomorphic adenomas, 2 lymphadenitis, 1 monomorphic adenoma and malignant pathologies of 2 mucoepidermoid carcinoma, 2 B-cell lymphomas, 1 adenocarcinoma, and 1 myofibrosarcoma. Surgical intervention was performed on all patients with standard parotidectomy incision for accessory parotid mass excision after identification and tracing of facial nerve and its branches.Conclusion
The present study provides support for a standard parotid incision with identification of the facial nerve at the time of surgical incision as this resulted in successful excision of accessory parotid tumors with favorable cosmetic results and without facial paralysis or tumor recurrence. Literature review of 152 cases of accessory parotid gland lesions, revealed a pooled incidence of 70% benign and 30% malignant. 相似文献6.
ObjectiveTo evaluate the presentation, treatments and outcomes in pediatric patients with salivary gland malignancies.Study designRetrospective chart review (1950–2012), Prospective phone interview.MethodsPatients ≤18 years old with a salivary gland malignancy treated at our institution were identified. Patients were also contacted by phone for a follow up survey.ResultsFifty-six patients were identified. Tumor origin was 88% parotid (n = 49), 5% (n = 3) submandibular and 7% (n = 4) minor salivary glands. Time from onset of symptoms to diagnosis was over one year (mean = 14.4 years). Fifteen out of 52 patients with major gland malignancy had a locoregional recurrence and local recurrences were almost all after initial enucleation. Two of these patients died of disease (overall disease specific survival = 96%). Three out of 4 patients with minor gland malignancy had a local recurrence and two patients with high grade pathology developed metastases and died of their disease (overall survival = 50%). On long term follow up survey in 13 patients (25%), 100% reported normal facial movement and 54% described symptoms of Frey's syndrome, which is higher than other reported series in children. Recurrence was noted up to 45 years after initial treatment.ConclusionsThe majority of malignant pediatric salivary gland tumors are low grade and have excellent survival, especially if found at an early stage. Minor salivary gland malignancies, particularly high grade, have a worse prognosis. Long term mild Frey's syndrome can be expected in approximately half of patients. We advocate a need for long term follow up and increased awareness among providers to diagnose these patients earlier. 相似文献

IntroductionCarcinoma ex pleomorphic adenoma (CXPA) is a rare malignant tumor of the parotid gland. We analyzed the clinical characteristics and treatment outcomes of CXPA of the parotid gland in patients managed for 11 years at this hospital.MethodsThe study included 17 cases of CXPA of the parotid gland from January 2010 to December 2020.ResultsOver 11 years, CXPA was the fourth most common parotid carcinoma, accounting for 9.4% of the 180 cases finally diagnosed as parotid carcinoma. Of the 17 cases of CXPA of the parotid gland, 12 lesions were removed by superficial parotidectomy, four lesions by total parotidectomy, and one lesion by radical parotidectomy. Four patients underwent neck dissection. The most common histopathology type was salivary duct carcinoma (n = 13, 76.5%). Postoperative radiation therapy (RT) was performed in 15 patients. Two patients (11.8%) experienced CXPA recurrence 14 and 19 months after surgery.ConclusionCXPA of the parotid gland was treated without recurrence in about 90% of the patients through surgery and postoperative RT. In the case of frankly invasive or adverse factors in the histopathological examination, more attention is required because CXPA recurrence may occur more frequently. 相似文献

Objective: To investigate the epidemiological and clinicopathological characteristics of salivary gland tumors in southwest China in order to provide data for clinical diagnosis and other similar research.Methods: Between March 2007 and December 2017, 2736 patients with salivary gland tumors were recruited, the clinical and pathological data were retrospectively analyzed.Results: A total of 2736 patients had a ratio of males to females of about 1.02:1. The ratio of benign to malignant tumors was 3.46:1. Pleomorphic adenoma and adenoid cystic carcinoma had 50.8% and 7.2%, respectively. About 65.4% tumors occurred in the parotid gland. There was no significant difference between the tumor in the left or right parotid and the use of cell phones. There were significant differences between gender and both the characteristics and locations of salivary gland tumors (p?.05). There were also significant differences between the pathological characteristics and location of the salivary gland (p?.05).Conclusions: The salivary gland benign and malignant tumors were more common in pleomorphic adenoma and adenoid cystic carcinoma, most occurred in the parotid gland. The minor gland tumors are lower than other parts of China. The incidence of parotid gland tumors is not related to the use of cell phones. 相似文献

IntroductionBenign tumors of the parotid gland comprise the majority of salivary gland tumors.ObjectiveTo review the clinical characteristics of parotid gland tumors submitted to surgical treatment by the same surgeon.MethodsRetrospective study with 154 patients who had parotid gland tumors. Clinical and histological data, type of surgery, and complications were assessed and described.ResultsThe main manifestation was a mass with a median evolution of 12 months for benign tumors and five months for malignant tumors. Ultrasonography was the most frequent complementary exam. Pleomorphic adenoma was the most common of the benign tumors, and mucoepidermoid carcinoma was the most frequent malignant tumor. Superficial parotidectomy with preservation of the facial nerve was the most common surgical procedure and reversible paresis of branches of the facial nerve was the most common complication.ConclusionsPleomorphic adenoma is the most common parotid gland tumor and superficial parotidectomy with preservation of the facial nerve is the most common and appropriate treatment for most low-morbidity tumors. 相似文献

IntroductionSalivary gland tumors are a diverse group of lesions, with various origins and extremely different behaviors, leading to a variety of outcomes for patients. Therefore, the need to discover novel markers with the ability to predict the behavior of benign and malignant salivary gland neoplasms is crucial. Syndecan-1 is a cell-surface protein with significant roles in various aspects of tumor function. Its expression in salivary gland neoplasms, especially their stromal component, has not been investigated.ObjectivesWe aimed to assess the immunopositivity of syndecan-1 in epithelial and stromal components of salivary gland neoplasms and to compare it between benign and malignant subtypes in addition to evaluating its correlation with clinicopathologic parameters.Methods133 salivary gland tumors were immunohistochemically stained with syndecan-1 and the intensity and percentage of this protein was determined, compared between the tumors and correlated with clinicopathologic factors.ResultsStatistical analysis of lesions with a sufficient sample size showed significant differences in percentage and intensity between both epithelial and stromal components of all tumors (p < 0.05). Pairwise-comparisons demonstrated significantly higher staining-percentage of epithelial cells (p = 0.02) in Warthin’s tumor compared to pleomorphic adenoma and adenoid cystic carcinoma. Similarly, significantly higher staining intensities and/or percentages was observed in mucoepidermoid carcinoma and adenoid cystic carcinoma compared to pleomorphic adenoma and Warthin’s tumor (p < 0.05). Of the clinicopathologic factors, there was only a significant negative correlation between stromal percentage of mucoepidermoid carcinoma and age and a significant difference between stromal intensity+percentage of adenoid cystic carcinoma and gender (p < 0.05).ConclusionsAccording to our findings we postulate that stromal syndecan-1 correlates with the behavior of salivary gland tumors, with malignant neoplasms demonstrating a higher expression, indicating a role for syndecan-1 in invasion and metastasis. 相似文献

PurposeParotid gland incidentaloma (PGI) management has not been well characterized in the literature. This study assesses clinicopathologic features, initial evaluation, management, and outcomes of PGIs discovered on various imaging modalities.Materials and methodsThis is a retrospective case series from a single academic institution. The study cohort included 34 patients with parotid gland incidentalomas discovered between January 2009 and December 2019.ResultsParotid gland incidentalomas were most frequently identified on magnetic resonance imaging (16 patients, 47.1%). Most patients (26 patients, 76.5%) underwent further evaluation with subsequent imaging, most often magnetic resonance imaging (18 patients, 69.2%), and fine needle aspiration biopsy (33 patients, 97.1%). Most tumors were benign on fine needle aspiration biopsy (19 patients, 57.6%). Most cases (21 patients, 61.8%) were managed with observation without parotidectomy. Malignant findings on fine needle aspiration cytology were associated with increased likelihood of undergoing parotidectomy (25% vs 0%; p = 0.04). Among the patients who received a parotidectomy, most (8 patients, 61.5%) had benign findings on final histopathology.ConclusionParotid gland incidentalomas were discovered across a diverse set of imaging modalities in our institution. Magnetic resonance imaging and fine needle aspiration were often performed for further evaluation. Most cases were found to be benign on fine needle aspiration and were managed with observation. These findings highlight the necessity of appropriate work-up for these tumors, and the need for shared decision making between the patient and the physician in selecting the appropriate treatment strategy. 相似文献

IntroductionFine needle aspiration biopsy is a valuable tool in preoperative evaluation of head and neck tumors. However, its accuracy in management of salivary gland tumors is debatable.ObjectiveWe aimed to investigate the efficacy and the accuracy of fine needle aspiration biopsy in parotid gland tumors.MethodsPatients who underwent parotidectomy between January 2008 and June 2017 due to parotid gland tumor were examined retrospectively. Patients with both preoperative fine needle aspiration biopsy and postoperative surgical pathologies were included. Preoperative fine needle aspiration biopsy was categorized as benign, malignant or suspicious for malignancy. Surgical pathology was grouped as benign or malignant. Surgical pathology was compared with fine needle aspiration biopsy, and sensitivity, specificity, accuracy and agreement between both tests were investigated.Results217 cases were evaluated and 23 cases were excluded because the fine needle aspiration biopsy diagnosis was non-diagnostic or unavailable. 194 cases were included. The mean age of the patients was 47.5 ± 15.88 (7–82). There were 157 benign, 37 malignant cases in fine needle aspiration biopsy, 165 benign and 29 malignant cases in surgical pathology. The most common benign tumor was pleomorphic adenoma (43.3%), and malignant tumor was mucoepidermoid carcinoma (4.13%). The diagnostic accuracy for fine needle aspiration biopsy when detecting malignancy was 86.52%. Sensitivity and specificity were 68.96% and 89.63% respectively. Positive predictive value was 54.05% and negative predictive value was 94.23%. There was moderate agreement between fine needle aspiration biopsy and surgical pathology (κ = 0.52). The sensitivity was 54.54% in tumors less than 2 cm while 77.77% in larger tumors. In tumors extending to the deep lobe, sensitivity was 80%.ConclusionFine needle aspiration biopsy is an important diagnostic tool for evaluating parotid gland tumors. It is more accurate in detecting benign tumors. In tumors greater than 2 cm and extending to the deep lobe, the sensitivity of fine needle aspiration biopsy is high. The use of fine needle aspiration biopsy in conjunction with clinical and radiological evaluation may help to reduce false positive and false negative results. 相似文献

IntroductionDemonstrate that carefully selected free flap patients may be discharged early after surgery without increasing the rates of postoperative complications or readmissions.MethodsBased on a published article in Laryngoscope 2016 of 51 free-tissue transfers, a retrospective chart review was performed on an expanded cohort who underwent free-tissue transfer for head and neck reconstruction between February 2010 and May 2018 and discharged by postoperative day 3.Results101 patients who underwent 104 free flaps with average age of 56 (3–84) years old were reviewed. Free flap indications included orbital and maxillary defects (n = 22), palatal defects (n = 16), nasal and septal defects (n = 16), cranioplasty and scalp defects (n = 16), mandibular defects due to osteoradionecrosis (n = 14), facial contouring and parotid defects (n = 12), and complex postsurgical and radiotherapy wounds or fistula closure (n = 8). Free flaps performed were anterolateral thigh (n = 97), radial forearm (n = 2), serratus (n = 2), latissimus (n = 1), fibula (n = 1) and supraclavicular (n = 1). The recipient vessels used via minimal access approaches were facial (n = 43), superficial temporal (n = 29), angular (n = 20) and others. There were 3 flap failures (2.9%) recognized in follow-up. No flap failures or perioperative complications were associated with early discharge. There were only 2 patients readmitted and 1 watched in observation within 30 days postoperatively.ConclusionAn updated review of our institutional experience with more than double the cohort size substantiates previous conclusions that early discharge after free-tissue transfer is a safe option in select patients. Moreover, earlier discharge is a critical management choice that reduces cost and decreases hospital-related adverse events. 相似文献

IntroductionWarthin tumors are the second most common benign tumors of the parotid gland. We examined the clinical features of Warthin tumors in our hospital, and analyzed the consistency within the literatures.ObjectiveThe aim of this study is to analyze the clinical features of Warthin tumors in our 10-year experience of 118 Warthin tumors undergoing surgery at a single institute.MethodsFrom December 2006 to December 2016, 110 patients who underwent surgical treatment for Warthin tumors were identified based on their medical records.ResultsA total of 118 parotid gland operations were performed in 110 patients. Almost 90% of Warthin tumors were found in males, and average patient age was 66.1 ± 6.1 years. The prevalence of smoking history was 89.1% (98/110). Eight patients (7.3%) had bilateral Warthin tumors. Seventy-seven lesions (65.3%) were located in the parotid tail portion, followed by 34 lesions in the superficial lobe (28.8%) and 7 lesions in the deep lobe (5.9%).ConclusionWe determined the appropriate extent of surgery depending on the fine needle aspiration cytology and tumor location by computed tomography scans. Partial facial dysfunction after the operation was detected in 12 cases, and facial nerve function recovered within 3 months. Only one patient experienced a recurrence, and was disease free after the re-operation. We suggest that our treatment algorithm, depending on the location of tumors and the result of fine needle aspiration cytology, can be useful to determine the appropriate extent of surgery for Warthin tumors. 相似文献

The occasional local recurrence of benign pleomorphic adenoma (PA) has generally been attributed to the vulnerability of the
tumor capsule. Although some reports have also noted the presence of satellite tumors associated with PA recurrence, only
few reports have focused on this issue. We paid special attention to the satellite lesions apart from the main tumors and
discussed their frequency, origin, nature and the ways of treating them. A total of 108 specimens of primary parotid gland
PA resected at the Okayama Saiseikai General Hospital from 1988 to 2008 were microscopically reviewed. Four (3.7%) patients displayed a main mass with satellite
tumors in a single parotid gland. The immunohistochemical analysis of p53 and Ki-67 index showed no distinct difference between
PAs with satellite tumors and those without. Satellite tumors surrounding the main mass of parotid PA is relatively rare.
In most cases, such satellite tumors will arise from capsular perforation of the primary tumor cells. Preoperative evaluation
to recognize the existence of satellite tumors would be important and capsular dissection should be discouraged. We could
not find any evidence suggesting that primary PA with satellite tumors could be more biologically aggressive than those without. 相似文献

IntroductionRecently it has been reported that a high preoperative neutrophil–lymphocyte ratio and platelet–lymphocyte ratio may be related to increased recurrence risk, tumor aggressiveness, and worsened prognosis in various malignancies.ObjectiveThe objective of this research is to explore whether neutrophil–lymphocyte ratio and platelet–lymphocyte ratio in parotid tumors may or may not be used as a cancer marker.MethodsThis retrospective research has been conducted on a total of 228 patients consisting of 83 healthy persons and 145 patients with a mass in the parotid gland, who applied to a tertiary referral center and underwent surgery. Patients have been divided into two groups by their histopathological findings as malignant or benign parotid tumor. A third group consisting of healthy people has been defined as the control group. Also the malignant parotid tumor group has been divided into two subgroups as early stage and advanced stage. The groups have been compared in terms of neutrophil–lymphocyte ratio, platelet–lymphocyte ratio and other laboratory data.ResultsThe average neutrophil–lymphocyte ratio values of malignant parotid tumor, benign parotid tumor, healthy control groups were 2.51, 2.01, 1.79 respectively and the difference was statistically significant (p < 0.001). There was no significant difference between advanced stage and early stage parotid tumor groups in terms of average neutrophil–lymphocyte ratio value (p = 0.782). In dual comparisons, the platelet–lymphocyte ratio value of patients in the malignant group was found out to be statistically significantly higher than that of benign and control groups (p < 0.001 and p = 0.001 respectively).ConclusionTo the best of our knowledge our research is the first in the medical literature comparing neutrophil–lymphocyte ratio and platelet–lymphocyte ratio in patients with parotid tumor. neutrophil–lymphocyte ratio and platelet–lymphocyte ratio can serve as cost-effective, repeatable, easily accessible, and helpful inflammatory markers in order to distinguish patients with malignant parotid tumor from healthy people. 相似文献

ObjectivesThe goals of resection of benign parotid gland tumor are complete resection of lesion and preservation of the facial nerve function. Traditionally, the bayonet-shaped incision (Blair incision: BI) and the modified face lift incision (mFLI) are commonly used for parotidectomy. However, concerns exist about the adequacy of exposure and identification of the facial nerve in anterior or superior parotid lesions. The aim of this study was to compare the surgical outcomes between BI and mFLI and to evaluate the adequacy, possible indications, and limitations of mFLI for the resection of benign parotid gland tumors located anteriorly or superiorly.MethodsThis retrospective study analyzed the medical records of 175 patients with various types of benign parotid tumor who underwent partial parotidectomy via BI (97 patients) or mFLI (78 patients). Tumors were divided into five categories depending on their location: anterior, superior, inferior, middle, and deep lobe tumors. The outcomes of operation were analyzed according to tumor location between the incision types.ResultsTumor locations were not significantly different between the two groups. Transient facial palsy occurred in 23 out of 152 patients (15.1%); permanent palsy was not observed in either group. The incidence rates of facial palsy were higher among patients with superior and deep lobe tumors; in the mFLI and BI groups, proportions of superior tumors were 22.2% and 27.2%, respectively, and those of deep lobe tumors were 35.7% and 23.5%, respectively. With regard to superior and anterior tumors, the incidence rate of postoperative facial palsy was insignificantly lower in the mFLI group (10.5%) than in the BI group (18.2%).ConclusionsThere were no differences in the incidence rates of postoperative facial palsy between mFLI and BI for any tumor location. Use of the mFLI is feasible for the resection of most benign parotid tumors located anteriorly or superiorly. 相似文献

ObjectiveWe evaluated microwave ablation (MWA) for treatment of isolated pharyngeal benign lesions, in terms of technical feasibility, efficacy, and safety.MethodsThe patients with pharyngeal benign lesions were treated with endoscopic MWA with a 2450-MHz single cooled-shaft microwave antenna and sent for histological examination. Postoperative pain intensity was measured via visual analogue scale (VAS) on the 12th hour and the third postoperative days.ResultsOf the 137 patients with pharyngeal benign lesions who met the inclusion criteria. The most commonly involved site was the uvula (n = 66, 48.2%), followed by the lateral pharyngeal wall (n = 37, 27.0%), the nasopharyngeal posterior wall (n = 23, 16.8%) and the soft palate (n = 11, 8.0%). All of the procedures were completed using local anesthesia and were well-tolerated by the patients. The ablation time was 5–10 min, with an average duration of 6.3 ± 1.8 min. The most common pathology was papilloma (n = 96, 70.1%), followed by nasopharyngeal cysts (n = 21, 15.3%), polyp (n = 10, 7.3%), epidermoid cysts (n = 8, 5.8%) and Thornwaldt cysts (n = 2, 1.5%). The mean VAS pain score was 2.36 ± 1.08 on postoperative 12th hour and 1.21 ± 0.54 on postoperative third day. At the 6-month follow-up examination, there were no severe complications, such as recurrence, bleeding, or synechiae of the nasal cavity, eustachian tube injury, in any of the patients.ConclusionsThe MWA for the treatment of isolated pharyngeal benign lesion is feasible and alternative to conventional surgical methods, it allows excision of the lesion while providing hemostasis, involves only a short ablation time and has a very low risk of complications. Most of our patients well-tolerate the procedure, which may be performed under local anesthesia in the outpatient setting. 相似文献

IntroductionBilirubin levels have been associated with risk of several malignancies. The association between pretreatment serum bilirubin levels and overall survival of patients with parotid gland carcinoma is unclear.ObjectivesIn this study, we assessed the effect of serum bilirubin levels to overall survival in malignant parotid tumors.MethodsThis study included a total of 35 patients, 15 female and 20 male. The mean age of these patients was 60.7 ± 14.5 years. All patients who were diagnosed with parotid gland carcinoma and underwent total parotidectomy between 2008 and 2018, were retrospectively assessed. The relationship between the overall survival of patients and total bilirubin, direct bilirubin, and indirect bilirubin levels was estimated. The receiver operating characteristic (ROC) curve analysis was performed to determine the optimal cut-off points.ResultsPatients with low direct bilirubin, total bilirubin and indirect bilirubin had significantly longer overall survival than those with high levels. Cut-off values for total bilirubin, direct bilirubin and indirect bilirubin were detected as 0.545 mg/dL, 0.175 mg/dL and 0.435 mg/dL, respectively.ConclusionIn our study, we observed that increased preoperative bilirubin levels are associated with reduced survival time in the postoperative period of patients with parotid gland carcinoma. 相似文献
