A clinical case of perforation of the maxillary sinus membrane during sinus lift surgery and a proposed methodology for the management of subsequent complications

Abstract

INTRODUCTION: Bony projections on the inner surface of the maxillary sinus are divided into two main groups: exostoses, which are rounded bone structures, and septa, defined as having a pointed end. Bony septa are common anatomical structures and can lead to complications during sinus augmentation procedures. MATERIALS AND METHODS: The study reports a clinical case of a vertical partial basal bony septum, where upon elevation of the sinus membrane, its perforation was observed (size >5 mm). RESULTS: The present study proposes a method of treatment of perforated sinus membranes.The post-surgical period was uneventful. The bone grafting material remained compact in the sinus augmentation site. CONCLUSIONS: The proposed method for the management of perforated sinus membranes can be applied in surgical procedures for perforations > 5 mm in size.
