Anatomical Study of the Middle Meatus with Emphasis to the Maxillary Ostium and Their Clinical Relevance

Introduction: The anatomical variations of the lateral wall of the nasal cavity may create technical difficulties during endoscopic sinus surgeries. Interventions involving the middle meatus are commonly performed as majority of the paranasal sinuses open into the osteomeatal complex. The present study was therefore designed to provide information on maxillary ostium in relation to the important anatomical landmarks and also about the variations possible in the morphology of the middle meatus
