“STUDY OF VARIOUS OSTIOMEATAL COMPLEX ABNORMALITIES BY ENDOSCOPY AND CT SCAN AND ITS MANAGEMENT”

Abstract

Background: The two cardinal factors in the maintenance of normal physiology of the paranasal sinuses and their mucous membranes are drainage and ventilation. Normal drainage of the paranasal sinuses depends on effective mucociliary clearance; this is dependant, among other things, on the condition of the sinus ostia.1 OBJECTIVES: To study the various sinonasal anatomical variations in the study population. MATERIAL & METHODS: Study Design: Prospective Hospital based observational study. Study area: Department of E.N.T, Narayana Medical College and Hospital, Nellore, Andhra Pradesh. Study Period: August 2016 to July 2017. Study population: All the
patients attending the E.N.T. outpatient department, who had chronic sinusitis for more three months duration not responding to the medical line of treatment and who were willing to undergo Functional Endoscopic Sinus Surgery. Sample size: study consisted a total of 50 cases. Sampling method: Simple random method. Results: The uncinate was typical in 29 (58%), medialized in 22 (44%), anteriorly turned in 1 (2%), hypertrophied in 6 (12%) and pneumatized in 2 (4%). The superior attachment of the uncinate process was as follows: middle turbinate in 21 (42%), lamina papyracea in 18 (36%) and skull base in 11 (22 %). Ethmoidal bulla: The bulla was typical in31 (62 %), large in 11 (22%) and hypoplastic in 8 (16 %). CONCLUSION: In view of the presence of these significant variations, we reemphasize the need for proper preoperative assessment in every patient in order to accomplish a safe and effective endoscopic sinus surgery
