An Endoscopic Study on the Prevalence of Accessory Maxillary Sinus Ostium in Patients with Chronic Rhinosinusitis in Dar es Salaam, Tanzania

Abstract

Aim: We aimed to determine the prevalence of and characterize accessory maxillary sinus ostium (AMO) in patients with chronic rhinosinusitis at a private health facility which serves the largest number of patients seeking treatment under private practice in Tanzania’s largest city. Methods: Fifty adult patients with symptoms of chronic rhinosinusitis attending the ENT clinic on an outpatient basis were selected and then computerized tomography scan of the nose and paranasal sinuses (CT scan PNS) was performed. Nasal endoscopy was done to all patients to determine the presence and location of AMO. Results: Of all the 50 studied patients, CT scan PNS depicted positive signs of rhinosinusitis in 35 patients (70%). Upon nasal endoscopy of the 35 patients, AMO was found in 25 patients (71.4%). Of the 15 patients with no depicted CRS upon CT scan, AMO was found in 4 (26.7%) patients. Conclusion: Nasal endoscopy provides additional evidence of obstruction of natural sinus ostia thus leading to chronic maxillary rhinosinusitis apart from CT PNS. Such observation is of importance to clinicians who are to execute management of these patients. an international, peer-reviewed, open access journal that focuses on all aspects of surgical procedures and interventions. Patient care around the peri-operative period and patient outcomes post-surgery are key topics for the journal. All grades of surgery from minor cosmetic interventions to major surgical procedures are covered. Novel techniques and the utilization of new instruments and materials, including implants and prostheses that optimize outcomes constitute major areas of interest. The manuscript management system is completely online and includes a very quick and fair peer-review system, which is all easy to use.
