Introduction Many patients undergoing functional endoscopic sinus surgery still have an uncontrolled clinical disease in the late post-operative period. Up to 11.4% of the patients will require a revision surgery. Findings such as the residual uncinated process and the lateralization of the middle turbinate were considered by some studies as being responsible for failure in the primary surgery. Objectives To describe the tomographical findings in adult patients undergoing revision endoscopic sinus surgery, the profile of those patients, and verify the mucosal thickening level of the paranasal sinus. Methods Data were collected from medical records and computed tomography reports of 28 patients undergoing revision sinus surgery on a private service in the city of Blumenau between 2007 and 2014. The score of Lund-Mackay was used to verify the mucosal thickening level. Results Among the 28 patients, 23 were reoperated once, 3 were reoperated twice, and 2 were reoperated 3 times. The most relevant findings were mucosal thickening of the maxillary sinus (89.28%), deviated septum (75%), thickening of the ethmoid (50%) and sphenoidal sinuses (39.28%), and pneumatization of the middle turbinate (39.28%). The average obtained in the Lund-Mackay score was 5.71, with most patients classified in the lower range of punctuation. Conclusion The analysis of the computed tomography scans showed persistent structures that may be responsible for the failure of the primary surgery. Computed tomography is a useful tool to plan the surgery and quantify the post-operative success.

Objectives: To examine the frequency in which angled endoscopes are necessary to visualize the true maxillary ostium (TMO) following uncinectomy and prior to maxillary antrostomy. Additionally, to identify preoperative computed tomography (CT) measures that predict need for an angled endoscope to visualize the TMO. Study Design: Retrospective study. Setting: Tertiary academic hospital. Patients and Methods: Patients who underwent endoscopic sinus surgery (ESS) between December of 2017 and August of 2018 were retrospectively identified. Cases were reviewed if they were primary ESS cases for chronic rhinosinusitis without polyposis and if they were at least 18 years of age. Results: Sixty-three maxillary antrostomies were reviewed (82.5% were from bilateral cases). Thirty-five cases (55.6%) required an angled endoscope in order to visualize the TMO. Of the preoperative CT measures examined, a smaller sphenoid keel-caudal septum-nasolacrimal duct (SK-CS-NL) angle was significantly associated with need for an angled endoscope intraoperatively to visualize the TMO (17.1° SD ± 3.2 vs 15.0° SD ± 2.9; P = .010). Conclusion: Angled endoscopes are likely required in the majority of maxillary antrostomies to visualize the TMO. This is important to recognize in order to prevent iatrogenic recirculation. The SK-CS-NL angle may help to identify cases preoperatively which require an angled endoscope to identify the TMO during surgery.

ABSTRACT Background Chronic rhinosinusitis (CRS) is diagnosed on the basis of symptoms, nasal endoscopic findings and computed tomography of the paranasal sinuses (CT PNS). Where indicated, functional endoscopic sinus surgery (FESS) is the surgical treatment. Objective To determine correlations between subjective symptom severity and objective endoscopic and radiologic findings in CRS and to compare these before and after FESS. Materials and methods Analysis of prospectively collected data of 20 patients undergoing FESS at a tertiary care medical center followed up for a minimum period of 6 months after surgery. RSI questionnaire-based symptom score, Lund-Mackay system-based endoscopic and CT finding scores were recorded preoperatively and at 8 weeks and 6 months postoperatively. Results Significant positive correlation was noted between the three parameters before surgery, especially endoscopic and radiological scores (r = 0.94 in the latter, p < 0.01 in all three). Postoperative improvement was statistically significant for all three parameters, even at the 6 months stage (p < 0.001). Postoperative correlations reduced significantly, especially between endoscopic and radiological scores. Conclusion This study showed the relevance of objective evaluation of routine parameters of CRS, preoperatively. It also confirmed the usefulness of FESS in indicated cases, in terms of statistical improvement of these parameters. However, repeat CT scans and the methods of scoring used by us may not be equally applicable in the long-term postoperative scenario. How to cite this article Deepthi NV, Menon UK, Menon IR.

AbstractIntroduction:Sphenoid sinus mucoceles represent only 1–2 per cent of all paranasal sinus mucoceles. Patients may present with a myriad of symptoms. Pre-operative investigations include nasoendoscopy, computed tomography and/or magnetic resonance imaging. Treatment is by endoscopic sinus surgery.Methodology:A retrospective review of the archives of the Singapore General Hospital otolaryngology department (1999–2006) identified 10 cases of sphenoid sinus mucocele. Patient demographics, presenting symptoms, investigations and treatment were evaluated.Results:The 10 patients identified (three women and seven men) had a mean age of 54.5 years (range 24–70 years). Thirty per cent of patients had a history of nasopharyngeal carcinoma treated with radiotherapy. Presenting symptoms, in order of decreasing frequency, were: ocular symptoms (50 per cent), headaches (30 per cent), nasal discharge (30 per cent) and facial pain (10 per cent). All patients underwent pre-operative computed tomography or magnetic resonance imaging. Twenty per cent of patients had evidence of intracranial involvement on imaging. All patients underwent uncomplicated transnasal sphenoidotomy and drainage of the mucocele. There was no clinical or radiological evidence of recurrence at a mean follow up of 29 months (range 4–90 months).Conclusion:Sphenoid sinus mucocele is a rare condition. In this study, radiation to the head and neck appeared to be a predisposing factor, and eye symptoms were the commonest presentation. Endoscopic sinus surgery is a safe and effective treatment modality.

Background Endoscopic sinus surgery is performed for many reasons, most commonly for chronic rhinosinusitis refractory to medical treatment. A paradoxical middle turbinate is an anatomic variant that can hinder endoscopic access to the sinuses. No publication has addressed how to surgically treat a paradoxical middle turbinate. Method We present a basic endoscopic surgical approach to conservatively resect a paradoxical middle turbinate in order to improve access to the middle meatus and the sinuses while preserving support and function. Conclusion Conservative remodeling of the paradoxical middle turbinate can provide access to the sinuses while maintaining a significant portion of the middle turbinate.
