The use of Mitomycin-C to reduce synechia in middle meatus in sinus surgery: preliminary results

Synechia is the most frequent complication after sinus surgery and has been reported in up to 36% of cases. Several types of materials have been used to reduce the incidence of synechia, including Mitomycin C (MMC).ObjectiveThis prospective study aimed to assess the effectiveness of topical MMC in the prevention of synechia after sinus surgery in humans.MethodsAt the end of surgery, MMC solution (1.0 mg/ml) was topically applied randomly to one of the middle meatuses (MMC group) of 14 patients while saline solution was applied to the contralateral meatus (control group). The author remained blind to the medicated side. Synechiae were classified as partial or total.ResultsThree patients had middle meatus synechia in the MMC group (21.43%) versus nine (64.29%) in the control group (p = 0.054). In the MMC group, all three middle meatus synechia were partial, while in the control group there were four partial (28.57%) and five total (35.71%) cases of synechia (p = 0.025).ConclusionsMitomycin C was not effective in preventing middle meatus synechia, but reduced the probability of total synechia formation.     

The importance of preoperative nasal endoscopy in patients with sinonasal disease

Functional endoscopic sinus surgery (FESS) has popularized the use of telescopes in sinus surgery and has emphasized the importance of nasal endoscopy and computed tomography (CT) in the evaluation of patients with diseases of the nose and paranasal sinuses. Variations in intranasal and sinus anatomy have been implicated in the etiology of chronic and recurrent sinusitis, and CT imaging has become an important diagnostic tool. Despite this, some patients present with symptoms and telescopic examination suggestive of sinonasal disease, yet demonstrate little abnormality on CT scan. The authors reviewed videoendoscopic and CT examinations of 100 consecutive patients with symptoms of sinus disease and found 9% of patients with abnormal telescopic examination in the context of negative CT findings. In those patients whose CT examinations were positive, telescopic nasal endoscopy was especially useful in delineating the type of soft tissue which obscured the area of the middle meatus. In those patients whose CT examinations were negative, telescopic examination demonstrated septal deflections, mucosal edema involving the middle meatus, as well as turbinate and adenoid hypertrophy. These findings demonstrate that telescopic nasal examination is an important diagnostic modality which often yields important information when evaluating patients with sinonasal disease.     

Endoscopic surgery with powered instrumentation for isolated sphenoid sinus disease

OBJECTIVE: Isolated sphenoid sinus disease (ISSD) is a relatively uncommon disease. In this study, we investigate the diagnosis and pathology of ISSD and compare endoscopic treatment with powered instrumentation with conventional surgical instruments for ISSD. METHODS: Ninety-six out of 2,263 patients who underwent endoscopic surgery were diagnosed with ISSD by nasal endoscopy and computed tomography scan. Ninety-six cases of confirmed ISSD were treated by endoscopic sphenoidotomy, of which 44 cases were operated using powered instrumentation and 52 using conventional instruments. All patients were followed up for a period ranging from 18 to 54 months (mean 26 months) and the surgical outcomes were retrospectively reviewed. RESULTS: The pathological findings of these patients included sphenoid sinusitis, fungal disease, sphenoid cyst, inverted papilloma, malignant tumor, sphenoid polyp, and foreign body. The most common initial symptom was headache, followed by visual changes and nasal symptoms. After endoscopic surgery, drainage of the sphenoid was accomplished in 87 of the 96 patients (91%). Of all patients, 9.4% (9/96) had recurrent incidence, 22% (21/96) sphenoid ostium synechia, and 51% (49/96) partial middle turbinectomy. Comparing the surgical outcomes between two operative approaches, recurrent incidence, sphenoid ostium synechia, and partial middle turbinectomy were significantly lower in the powered instrumentation group (2, 7, and 14%) than in the conventional instrument group (15, 35, and 83%;p < 0.05). No serious complication occurred in either group. CONCLUSIONS: Powered instrumentation is more effective than conventional instruments in the treatment of ISSD and provides a minimally invasive surgical approach to the sphenoid sinus.

Role of mitomycin-C in prevention of post operative adhesions after endoscopic sinus surgery--a prospective study

To evaluate the role of Mitomycin-C in preventing synaechiae formation and ostial stenosis following endoscopic sinus surgery. This prospective study was conducted in VMMC and Safdarjung hospital from November 2007 to August 2008. 30 subjects aged between 16 and 60 of either sex in two groups were included in the study. All these patients with bilateral nasal polyposis underwent endoscopic sinus surgery with topical application of Mitomycin-C and were subjectively and objectively assessed for improvement of symptoms and post operative synaechiae formation. Patients showed improvement in subjective symptoms mainly nasal obstruction and hyposmia as well as decreased incidence of synaechiae formation and ostial stenosis post surgery following Mitomycin-C application. After doing this study we could conclude that Mitomycin-C applied topically following endoscopic sinus surgery was helpful in improvement of symptoms like nasal obstruction and hyposmia as well as decreased adhesion rate and middle meatal antrostomy closure rate. Topical application of Motomycin-C was safe in a dose of 0.4-0.8?mg/ml applied over 5?min and offered significant improvement both subjectively and objectively.     

Functional endoscopic ethmoid bone revision in inflammatory paranasal sinus diseases in childhood]

A total of 57 children aged between 5 and 15 years underwent endoscopic ethmoid surgery for recurrent acute or chronic rhinogenic sinusitis, chronic sinusitis associated with bronchial asthma or chronic bronchitis, early rhinogenous orbital complications and paranasal sinus disease associated with mucoviscidosis. The indications for surgical intervention are based on symptoms, the findings on nasal endoscopy and a CT scan of the paranasal sinuses in the coronal plane. The preoperative examination shows that in childhood there are endoscopically detectable anatomical variations of the ethmoid bone (pneumatised middle nasal concha, reversed curvature of the middle turbinate and contact between the uncinate process and the turbinate) that create the conditions for the development of inflammatory paranasal sinus diseases. Careful elimination of these obstructions can accomplish complete cure of the inflammation, and early orbital complications can be treated effectively by combination of surgery with infusion of antibiotics. All surgery was performed under endotracheal anaesthesia using the endoscopic technique described by Messerklinger. The follow-up period was between 6 and 18 months. With the exception of children suffering from mucoviscidosis, cure of the paranasal sinus disease and rhinomanometrically demonstrable improvement of the nasal breathing was achieved in all cases. On the basis of our results a conservative endoscopic approach is recommended as an effective surgical method for the treatment of paranasal sinus disease in childhood.     

Endoscopic sinus surgery in chronic rhinosinusitis and nasal polyposis: a comparative study

Nasal polyposis are common presentations in patients of chronic rhinosinusitis and are considered to be associated with more severe forms of disease with poor treatment outcome. The presentation and treatment outcome after endoscopic sinus surgery in patients of chronic rhinosinusitis and nasal polyposis have been analysed in this study. A prospective analysis of 90 patients of chronic rhinosinusitis who were classified into two groups depending on presence and absence of nasal polyps was performed in the study. The two groups were evaluated using subjective (patient complaints) and objective (computed tomography scan and endoscopy scores) criteria. Preoperative data were compared with data obtained 12?months post endoscopic sinus surgery. The study included 38 patients of chronic rhinosinusitis and 52 patients of nasal polyps. The patients of nasal polyp group presented with increased severity of symptoms of nasal blockage, nasal discharge and reduced sense of smell as compared to the chronic rhinosinusitis group who had significantly higher presentation of headache and facial pain. The preoperative CT scan revealed significantly higher bilateral disease with increased involvement of multiple sinuses in nasal polyp group. Post endoscopic sinus surgery both the groups showed significant improvement in their symptoms with the nasal polyp group demonstrating reduction in improvement on 1?year follow up. In our study we have found the patients with chronic rhinosinusitis and nasal polyp have varied severity of symptoms with the nasal polyp group having higher nasal symptoms and increased severity as compared to chronic rhinosinusitis group. Though the universal rationale of management by adequate drainage and ventilation of sinus is similar in both groups, there is a reduction in both objective and subjective scores during 1?year follow up in the nasal polyp group.

Comparative outcomes of endoscopic sinus surgery in patients with chronic sinusitis and nasal polyps

This study was carried out to compare the outcomes of endoscopic sinus surgery in patients with chronic sinusitis without nasal polyps (CRS) and those with nasal polyps (NP). We also sought to determine the correlation between preoperative computed tomography (CT) findings and postoperative endoscopy and symptom score improvement. Data were collected from two groups of patients diagnosed as CRS with and without nasal polyps that underwent functional endoscopic sinus surgery with a 1-year postoperative follow up. Preoperative symptoms, CT scores, and endoscopic scores were recorded. Postoperative symptom and endoscopic scores were recorded at 1, 6, and 12 months. Assessment of symptoms was performed subjectively using visual analogue scoring (VAS). CT scan findings were scored using the Lund–Mackay system. Endoscopic examination findings were scored according to the staging system proposed by Lanza and Kennedy. The correlations between the CT score, endoscopic scores and VAS scores were calculated. There was a statistically significant correlation between the preoperative CT, symptom, and endoscopic scores. Postoperative symptom and endoscopic scores also showed a significant correlation. Total CT scores of the CRS group were significantly lower than the scores of the NP group. Also preoperative endoscopy and symptom scores were statistically lower in CRS group compared to NP group. Endoscopy total scores and symptom total scores of both groups were significantly decreased at postoperative 12th month. Statistically significant difference was observed between the preoperative and postoperative symptom and endoscopy scores. The patients with polyps had higher symptom scores and worse objective findings compared to the patients with CRS. In all patients groups, objective and subjective scores seemed to correlate well preoperatively and postoperatively. These data suggest that endoscopic sinus surgery provides significant symptomatic relief and endoscopic healing in patients with CRS and NP.

Efficacy of controlling rhinosinusitis on the prevention of complications in pituitary surgery with transsphenoidal approach

Objective

The microscopic transcolumellar transseptal transsphenoidal approach (TSA) is the one of the most widely used methods for the surgical treatment of sellar and parasellar lesions. But nasal and paranasal sinus inflammation is the relative contraindications of TSA. This study was performed to investigate the results of pre TSA treatment options according to the degree of nasal and paranasal sinus inflammation on the paranasal sinus computed tomography scan (PNS CT).

Methods

From January 2005 to September 2010, 145 consecutive patients underwent operation of pituitary lesions through the TSA. The preoperative CT images for these patients were reviewed, and 26 patients were identified with sinus opacification on PNS CT. We then analyzed presenting symptoms, physical and endoscopic examination, Lund–Mackay score on PNS CT and preoperative management of the sinus problem retrospectively.

Results

Twenty-six patients had sinus opacification on PNS CT. Eight patients had the symptoms of sinusitis corresponding to PNS CT finding, so they had therapeutic antibiotics, and had TSA after symptomatic improvement. Three patients had the symptoms of sinusitis and sinus opacification with mean Lund–Mackay score of 5.33, so they underwent endoscopic sinus surgery first, and they got TSA a few months after. One patient underwent endoscopic sinus surgery and TSA simultaneously. No patient had a serious complication including intracranial infection.

Conclusion

TSA is a relatively safe technique, but intracranial complication after surgery may be fatal. Therefore rigorous evaluation and management is mandatory. It is especially important to treat rhinosinusitis issues preoperatively. Our preliminary data may be helpful to evaluate and manage the paranasal sinus inflammation before TSA.     

慢性鼻-鼻窦炎手术预后的临床影响因素分析

目的 分析慢性鼻-鼻窦炎(chronic rhinosinusitis, CRS)手术预后影响因素,为CRS的治愈提供有效借鉴。 方法 随机选取90例2014年5月至2015年11月收治的CRS患者,均行鼻窦冠状位CT扫描与鼻内镜检查确诊。行连续糖皮质激素喷鼻(每日200 μg)与抗炎治疗3 d后,实施鼻内镜手术治疗,对影响手术治疗效果的相关因素进行分析。 结果 术前患者头部胀痛、鼻塞以及鼻后滴漏症状非常严重,术后患者以上症状获得有效改善,但全身不适感与嗅觉减退症状改善并不显著。患者术后24周、48周的视觉模拟量表(visual analog scale, VAS)评分相比于术前存在明显差异(P<0.05)。患者并发鼻息肉与否、长期使用鼻减充血剂与否、有鼻窦手术治疗史与否、手术治疗后坚持实施综合治疗与否是对手术预后产生影响的相关因素。 结论 CRS行鼻内镜手术治疗治疗效果较为确切,可有效改善患者临床症状。术前认真询问患者以往病史,强化对患者变应原检测,术后行后续综合治疗,对患者术后治疗效果的提升具有重要意义。

Selective irrigation of the sinuses in the management of chronic rhinosinusitis refractory to medical therapy: a promising start

BACKGROUND: Although endoscopic sinus surgery has been widely used for the treatment of chronic rhinosinusitis, some patients fail to derive clinical benefit from this procedure. We evaluated the efficacy of a treatment regimen consisting of selective irrigation of diseased sinus mucosa with topical antibiotics and steroids in conjunction with oral antibiotics and steroids. METHODS: Twenty patients suffering from chronic rhinosinusitis and resistant to medical treatment (mean duration 3.4 years) underwent intubations of the affected maxillary and/or ethmoid sinuses for irrigation for a duration of 21 to 30 days. A computed tomographic (CT) scan of the paranasal sinus was taken both pre- and post-treatment and staged according to the Lund-MacKay system. Clinical symptoms were scored for rhinorrhea, facial pain, nasal congestion, and smell at least 2 months prior to treatment and approximately 18 months after the follow-up. RESULTS: The clinical experience with the technique of intubation and irrigation was well tolerated by all patients. We found an improvement in all symptom scores, including rhinorrhea, nasal congestion, smell (n = 20; p < .001), and facial pain (n = 20; p < .01). Similar improvements were seen on the CT scans, with reduced staging from 14.6 +/- 1.1 to 5.6 +/- 1.1 (p < .001). Only three patients did not respond to selective irrigation of the sinuses and needed further surgery. CONCLUSION: These results suggest that sinus irrigation could provide a reasonable and effective alternative to ethmoidectomy with drainage procedures and offer promise for the treatment of patients with chronic rhinosinusitis who are resistant to medical treatment.     

Sinonasal outcome under aspirin desensitization following functional endoscopic sinus surgery in patients with aspirin triad

Recalcitrant forms of recurrent nasal polyposis are problematic for patients as for rhinosurgeons. In aspirin-sensitive patients, aspirin desensitization is supposed to prevent recurrence by targeting the metabolism of arachidonic acid. Aspirin-sensitive patients (n = 65) following aspirin desensitization after functional endoscopic sinus surgery (FESS) for recurrent nasal polyposis under daily intake of 500-mg aspirin were compared to a post-FESS group (n = 81) of aspirin-sensitive individuals using exclusively topical mometasone. Quality of life (QoL) scores including sinonasal, pulmonal and general QoL items as well as endoscopic endonasal examination findings were evaluated during the postoperative follow-up period. After a follow-up period of minimum 18 months, a significant improvement in nasal obstruction, rhinorrhea, post nasal drip, sense of smell, facial pain, sleep quality and further general QoL items in desensitized patients was found compared to aspirin-sensitive controls. Improvement in sinonasal symptoms was evident, whereas the severity of asthmatic symptoms showed no significant changes. Although the pathophysiology of aspirin sensitivity is still not fully understood and the therapy is not sufficiently investigated, aspirin desensitization seems to have a positive effect on QoL scores concerning sinonasal symptoms and should be regarded as a possible postoperative treatment modality for recurrent nasal polyposis in aspirin-sensitive individuals.     

Diagnosis of surgical sinusitis using nasal endoscopy and computerized tomography

The ability to identify surgical sinus disease using diagnostic nasal endoscopy and coronal CT scanning of the paranasal sinuses is studied prospectively. Fifty consecutive patients with symptoms of chronic sinusitis lacking surgical indications by traditional work-up comprise the patient population. Sixty percent had endoscopic or CT indications for surgery. There was a 90% correlation between endoscopy and CT examination with the combined work-up being more accurate than either modality alone. Functional endoscopic sinus surgery was performed in 18 cases. There were no major complications. Approximately 89% of the postoperative group report significant improvement, with 55.6% reporting total relief of symptoms. A complete endoscopic sinus work-up can often identify surgically correctable sinusitis despite normal routine rhinoscopic and plain-film examination. It is therefore, warranted in those patients with a suggestive history.
