Influence of polyps on outcomes after endoscopic sinus surgery

OBJECTIVE: To determine clinical and comparative outcomes for endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS) with polyposis. METHODS: Two cohorts of adult patients with refractory CRS with and without nasal polyps were prospectively studied before and after ESS (minimum follow-up, 12 months) with the Rhinosinusitis Symptom Inventory (RSI). For the non-polyp and polyp cohorts, RSI symptom domains and medical resource utilization were compared in the preoperative and postoperative states. Corresponding effect sizes were computed and compared between cohorts to determine the effect of polyps on prognosis after ESS. RESULTS: A total of 165 non-polyp and 86 polyp patients were enrolled. Polyps were more common in female patients (2:1, P = .025); age (mean, 42.9 years) and follow-up (18.5 months) were similar between groups. Lund scores were significantly higher for polyp patients (13.7, SD 4.8) vs. non-polyp patients (8.1, SD 5.3, P < .001). At baseline, polyp patients reported lower symptom scores for facial, oropharyngeal, and systemic RSI symptom domains (all P < .012); nasal and total symptom domains were similar between groups. Both non-polyp and polyp groups obtained significant symptomatic benefit from ESS with effect sizes for RSI symptom domain improvements ranging from 0.89 to 1.38 and 0.43 to 1.19, respectively (all P < .001). There were no significant differences between groups in symptomatic improvement, excepting oropharyngeal symptoms (better improvement in non-polyp group, P = .024). Non-polyp patients decreased medical resource consumption more significantly than did polyp patients. CONCLUSIONS: Both non-polyp and polyp patients derive similar clinically significant symptomatic improvement after ESS. These similarities suggest that polyp patients do not necessarily have a poorer symptomatic outcome after ESS.     

Endoscopic and quality-of-life outcomes after revision endoscopic sinus surgery

OBJECTIVES: First, to examine the impact of endoscopic sinus surgery (ESS) on endoscopic and quality-of-life (QOL) outcomes after revision ESS as compared to primary ESS. Second, to evaluate whether or not other risk factors and/or co-morbidities influence the relationship between revision surgery status and outcomes of ESS. STUDY DESIGN: Prospective observational study with an internal comparison group. METHODS: Preoperative computed tomography scores, pre and postoperative endoscopy scores, and two validated disease-specific QOL instruments, the Rhinosinusitis Disability Index (RSDI) and Chronic Sinusitis Survey (CSS), were collected on a prospective cohort of patients undergoing ESS for chronic rhinosinusitis. Data were analyzed using Pearson's chi and multiple logistic regression models. RESULTS: Mean preoperative Lund-Mackay computed tomography scan scores were similar in primary and revision surgery patients. In patients without polyps, revision ESS patients were 3.88 times more likely to improve on endoscopy scores than primary ESS patients (95% confidence interval 1.70, 8.83; P = .001). In nasal polyp patients, there was no difference by revision status (odds ratio 0.48; 95% confidence interval 0.15, 1.59; P = .23). The odds of improving on the RSDI (odds ratio 0.51, 95% confidence interval 0.25, 1.04, P = .065) and CSS (odds ratio 0.98, 95% confidence interval 0.51, 1.89, P = .950) were not significantly different by revision status. CONCLUSIONS: Both revision and primary ESS patients improved after ESS with regard to endoscopy, RSDI, and CSS scores. In non-polyp patients, revision ESS patients were more likely to improve on endoscopy scores than primary ESS patients; there was no difference in polyp patients by revision status. Revision ESS patients and primary ESS patients were equally as likely to improve on two QOL instruments.     

A contemporary review of endoscopic sinus surgery: Techniques,tools, and outcomes

Chronic rhinosinusitis is estimated to nearly 25 million people annually in the United States alone. The medical management of these patients is often successful; however, when medical management fails, surgery may be indicated to bring relief. Unfortunately, surgery for chronic rhinosinusitis is not standardized and we remain without a consensus on both the extent of surgery required and the manner in which it is performed. In the past 25 years, three philosophies or schools of thought have arisen to help guide the surgical treatment of chronic rhinosinusitis. Functional endoscopic sinus surgery aims to surgically treat problem areas by ventilating the sinuses through the natural ostia and addressing all diseased sinuses when necessary. This procedure is not standardized and is patient and surgeon dependent. The minimally invasive sinus technique has been proposed as a method whereby each surgical procedure is standardized regardless of disease severity. Lastly, balloon catheter dilatation of the sinus ostia, which by itself is not truly a procedure, is also discussed as a separate philosophy since these specific tools used during endoscopic sinus surgery have quickly energized the sinus community. All three schools of thought possess benefits and drawbacks, even when used appropriately. The concepts, tools, and technologies will be reviewed here as well as outcomes in the hopes that this article will provide an understanding of the surgical options to successfully treat chronic rhinosinusitis.

Novel endoscopic scoring system after sinus surgery

Objective

To propose a simple post-operative endoscopic scoring system for use after endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis (CRS), and to demonstrate the usefulness of this approach.

Methods

Subjects comprised 116 patients (84 men, 32 women; mean age, 54 years) with CRS who were analyzed endoscopically and radiologically after ESS between 2006 and 2012. The study was designed as a case series with planned data collection in the setting of university medical centers. Patients were followed-up for ≥6 months after ESS (mean, 13.1 months). Both pre- and post-operative computed tomography (CT) findings of each sinus and olfactory cleft (OC) were scored according to the Lund–Mackay scoring system: 0, normal; 1, partially; or 2, completely occupied. CT score represents the total score expressed as a percentage of the maximum possible score (12 points per side). Post-operative endoscopic score (E score, %) was calculated as the maximum score according to physical findings on each operated sinus and OC: 0, normal; 1, partially diseased; or 2, completely closed. Post-operative course using E score was verified by comparison with the Lund–Kennedy (L–K) scoring system.

Results

E score was easily and quickly determined. Interclass correlation coefficient among 10 otolaryngologists indicated high-level inter-rater reliability (0.922). E score correlated strongly with both CT score (n = 116, p < 0.0001, r_s = 0.755) and L–K score (n = 79, p < 0.0001, r_s = 0.723).

Conclusion

Endoscopic evaluation using E score for sinuses and OCs after ESS is a useful method, together with L–K score for the nasal cavity and radiological study.     

Important clinical symptoms in patients undergoing functional endoscopic sinus surgery for chronic rhinosinusitis

OBJECTIVE: To evaluate the prevalence and severity of individual Rhinosinusitis Task Force (RSTF) symptoms in patients with chronic rhinosinusitis (CRS) undergoing functional endoscopic sinus surgery (FESS). METHODS: Retrospective analysis of prospectively collected data in 201 patients treated with FESS. The prevalence and severity of individual RSTF major and minor symptom scores graded on a visual analogue scale (VAS) were compared. Correlation between absolute improvement in individual symptom scores at 1-year postoperative was performed. RESULTS: One-hundred fifty-eight of 201 patients met inclusion criteria giving a response rate of 78%. The average age was 49.4 (range 18-80) with a male-to-female ratio of 1.1:1. The preoperative leading mean symptom scores were postnasal drip (5.8 +/- 0.3), nasal obstruction (5.7 +/- 0.3), and facial congestion (5.1 +/- 0.3). These symptoms were also the most prevalent with 82%, 84%, and 79% of patients reporting these symptoms, respectively. Postoperative symptom improvements were significant (P < .0001) across all RSTF domains except fever. The highest percentage improvement was seen with facial congestion (93%), nasal obstruction (92%), and postnasal drip (85%). Multivariate analysis revealed significant (P < .0001) high correlation between improvements of facial pain/pressure with facial congestion (R = 0.72), facial congestion with nasal obstruction (R = 0.65), and facial pain/pressure with headache (R = 0.72). CONCLUSION: The top three RSTF symptoms were postnasal drip, nasal obstruction, and facial congestion in terms of prevalence and severity. Symptom scores improved after FESS. Of these symptoms, the degree of improvement of facial pain/pressure, facial congestion, nasal obstruction, and headache are highly correlated.     

Smoking in chronic rhinosinusitis: a predictor of poor long-term outcome after endoscopic sinus surgery

OBJECTIVE: This study was designed to determine whether smoking patients have poorer outcomes after endoscopic sinus surgery (ESS) based on a reliable validated rhinosinusitis-specific quality-of-life outcomes test. STUDY DESIGN: Retrospective chart and computed tomography (CT) review with telephone and letter questionnaire. METHODS: Charts of 230 adult patients undergoing ESS for chronic rhinosinusitis between January 1995 and December 1998 were reviewed. Each participating patient completed a detailed questionnaire, including the Sino-Nasal Outcome Test-16 (SNOT-16), at an average of 52 months after surgery. Preoperative CT scans were reviewed and the findings used to stage the patients' conditions. Multivariate analysis was used to assess these data. RESULTS: Eighty-two patients completed the questionnaire, with 26 who smoked at the time of surgery and continued to smoke at the time of answering the questionnaire (Smokers). Average SNOT-16 score in Smokers was 27.5, versus 18.2 in those who did not smoke at the time of surgery (Non-Smokers). There was a statistically significant correlation between elevated SNOT-16 scores and smoking (P <.001) and antibiotic use within the past year (P <.001). There was an association between high SNOT-16 scores and both prior smoking and passive smoke exposure that did not reach statistical significance (P =.055 and P =.267, respectively). CT staging scores and prior ESS were not statistically correlated with SNOT-16 scores. CONCLUSIONS: Smoking is associated with statistically worse outcomes after ESS based on average SNOT-16 scores. Although no investigator has proved that the effects of smoking on sinonasal health are reversible, we counsel smoking patients considering ESS about the desirability of smoking cessation (for this and many health reasons), and the possibility of a poorer postsurgery outcome should they continue smoking.     

A prospective study of olfaction following endoscopic sinus surgery with adjuvant medical treatment

Few studies on the outcome of endoscopic sinus surgery have assessed the effect of this treatment on the sense of smell. We have collected data prospectively on 115 patients, before and 6 weeks after surgery. All patients had bilateral chronic rhinosinusitis. Visual analogue and a 4-grade, patient-rated symptom score related to olfaction was collected. Patients were also asked after surgery whether their sense of smell was normal, better, a little better, the same, a little worse or worse. Paired phenylethyl methyl ethyl carbinol olfactory detection thresholds were determined for 102 of the patients. All parameters showed a statistically significant improvement (P < 0.001). Acoustic rhinometry was performed pre- and postoperatively in 96 patients. The improvement in all olfactory symptom scores was found to correlate with the increase in nasal volume (Spearman rank correlation: visual analogue score, P < 0.005; 4-grade scale, P = 0.03; ‘better, same, worse’ scale, P = 0.001).     

Paranasal sinus exostoses: Possible correlation with cold temperature nasal irrigation after endoscopic sinus surgery

Exostoses of the external auditory canal (EEAC) are a commonly encountered clinical exam finding; however, exostoses in other locations are vanishingly rare. The postoperative paranasal sinuses are penetrated with cold water solutions, the reputed etiological agent for EEAC, and development of exostoses in this unexpected location may be observed endoscopically. The surprising appearance of these protuberant lesions within the sinuses could be mistaken for more ominous processes, subjecting the patient to biopsy, surgery, or unnecessary medical therapy. The radiologic appearance of exostoses within the paranasal sinuses is herein reported for the first time, and care is taken to distinguish these bony lesions from the osteoneogenesis of chronic inflammation.

Microscopic endonasal surgery of nasal and paranasal cavities

Objective

To present the experience of our department on microscopic surgery of the nose and sinuses and compare our results with those of other standard approaches. Furthermore we attempt to specify the main indications for the use of the method.

Methods

During the period between January 1990 and December 2002, the prementioned technique was performed in a total of 250 patients. The preoperative evaluation, surgical technique and postoperative management of all patients are described in detail.

Results

Most common diagnoses included nasal polyps and chronic rhinosinusitis. The average age of patients was 42 years. Males accounted for 48%. No major postoperative complications were noted. Minor complications such as epistaxis and midfacial pain were observed in 24% of cases. While the majority of patients reported severe symptomatology preoperatively, 91% reported substantial improvement of their clinical condition within 3 months after surgery.

Conclusion

Microscopic surgery is a technique which can be used alternatively to traditional procedures. It provides an excellent, clear, stereoscopic vision and allows the surgeon to work bimanually. Complications are rare and easily controlled. Our experience favors the use of microscopic technique compared to common endoscopic approaches, especially in cases of nasal polyps and chronic rhinosinusitis.     

Cytological characterization of persistent paranasal sinus secretions after endoscopic sinus surgery

BACKGROUND: The aim of this study was to characterize the cellular composition of persisting sinus secretions after endoscopic sinus surgery (ESS). METHODS: Consecutive adult patients with persisting abnormal sinus secretions post-ESS were prospectively evaluated. Sinus secretions were aspirated and submitted for cytological analysis. Semiquantitative cell counts were obtained for epithelial cells (graded as present or absent), eosinophils (graded on a 4-point Likert severity scale), and neutrophils (3-point Likert scale). Prior operative histopathology from ESS and Lund CT scores were reviewed. Statistical analyses were conducted to determine the relationships between preoperative Lund score, operative histopathology, and subsequent cellular infiltrate in sinus secretions. RESULTS: Forty-three patients (mean age, 49 years) were enrolled. Epithelial cells were present in 13 (30.2%) of these individuals. Cytological eosinophilia was rated as absent in 14 (32.6%) cases, mild in 5 (11.6%) cases, moderate in 18 (41.9%) cases, and severe in 6 (14.0%) cases. Neutrophil presence was absent in 24 (55.8%) cases, present/mild in 15 (34.9%) cases, and severe in 4 (9.3%) cases. No significant correlation could be found between the presence of each of these three cell types, the presence or absence of polyps, or preoperative Lund score (all p > 0.05). Sloughed epithelial cell presence was inversely but significantly correlated with original sinus histopathological inflammation (Spearman's rho, -0.348; p = 0.04); eosinophilic cytology tended to increase with prior operative histopathology inflammatory grade but neutrophils did not. CONCLUSION: The cytological profile of persisting secretions after ESS is dominated by eosinophils and to a lesser degree neutrophils. The presence of sloughed epithelial cells may signify ongoing mucosal damage from persisting sinonasal inflammation.

鼻腔冲洗在慢性鼻窦炎鼻内镜术后治疗中的应用研究

慢性鼻窦炎（CRS）是鼻窦黏膜的慢性炎症性疾病,其病因学及病理生理机制复杂。随着基础和临床研究不断深入,其诊断、治疗策略逐渐向个体化和精准化方向发展。手术治疗是CRS整体治疗的重要组成部分。鼻内镜手术因其功能性和微创性成为目前CRS首选的外科治疗手段,但是术后鼻腔、鼻窦黏膜仍处于炎症环境中,若处理不当会影响手术疗效。临床研究证实,鼻内镜手术后行鼻腔冲洗可改善症状,促进术腔恢复。本文将从冲洗液、冲洗方法、冲洗工具等方面进行综述,为鼻腔冲洗临床应用提供参考。     

The contemporary practice of functional endoscopic sinus surgery: a nationwide survey

Recent years have seen a rapid growth in the practice of functional endoscopic sinus surgery (FESS). Its introduction into clinical practice has, however, been conspicuous by an absence of good scientific evidence that it is superior to previous techniques. This postal questionnaire survey aimed to identify the diversity in the practice of FESS at a national level and, as a result, highlights areas of patient management requiring standardization. All full members of the British Association of Otolaryngologists—Head and Neck Surgeons (BAO-HNS) were contacted, 64% responded: 14% of surgeons do not always perform preoperative computerized tomography (CT) scanning; only 25% use grading systems for symptoms and/or CT assessment; a wide variety of topical agents are used both before and after operation; nearly half (47%) no longer operate principally under endoscopic vision but via TV monitors; and the majority of surgeons review patients more than 1 week after surgery with a minority advocating earlier postoperative assessment.     

Quality of life after endoscopic sinus surgery in refractory pediatric chronic rhinosinusitis

ObjectiveThe present study aims to evaluate the role of Endoscopic Sinus Surgery (ESS) in refractory pediatric Chronic Rhinosinusitis (CRS) and to assess the change in quality of life after ESS.Materials and MethodsThis prospective interventional study included 35 children (aged between 6 and 12 years) of refractory CRS, not responding to 4 weeks of maximal medical therapy attending the pediatric ENT clinic of a tertiary referral centre. Study period was from November 2013 to March 2016. This patient pool underwent Non Contrast Computed Tomography scan (NCCT) paranasal sinuses and diagnostic nasal endoscopy and those fulfilling the requisite inclusion criteria underwent Endoscopic sinus surgery. Global assessment of Rhinosinusitis Symptom severity score and SN-5 quality of life score of the patients was assessed preoperatively and 1 year after the surgery.Results91.4% children showed an improvement in the total symptom score with a statistically significant (p value < 0.001) reduction in the mean total score postoperatively. Similarly 91.4% of the children showed an improvement in their quality of life with a statistically significant (p value < 0.001) difference seen in the average SN-5 scores after ESS. No major complications were encountered in any of the cases.ConclusionESS is a safe and effective surgical management for children with CRS refractory to maximal medical therapy leading to an improvement in their quality of life.
