Abstract

Aims: To study the incidence of anatomical variations of osteo meatal complex common in chronic sinusitis patients. Materials and methods: This is a Prospective Study in patients attending to ENT op, who had symptoms of Chronic rhinosinusitis, who are not responding to medical management . A total number of 50 patients who had clinical symptoms suggestive of Chronic rhinosinusitis, sent for evaluation following a standard proforma and the patients are examined with standard diagnostic procedures systematically and when needed. Details of patients regarding were recorded. Results: All patients have at least one variation from normal anatomy.88%patients had more than one anatomical variation and the remaining 12% had one anatomical variation. About 68%of patients had bilateral involvement.Nasal septal deviation is the commonest anatomic variation and onodi cell, pneumatised septum are the least variants. Also there were a strong correlation between the unilateral concha bullosa and contra lateral septal deviation, which was evident based on studies. Concha bullosa, bulla ethmoidalis and septal deviation account for more than 90% of all the anatomical variations. Conclusions: By evaluating anatomical variations prior to surgery, we may both assure that the condition is completely cleared up and avoid unintended problems during surgery.
