ABSTRACT:
Background: The most frequent complication encountered while performing sinus floor elevation augmentation is membrane perforation. The incidence of this complication has been reported to span from 10% to 56%. A vast array of techniques have been reported to manage the different types of perforations.
Objective: The objective of the present study is to report on a modification of a previously published procedure that can be used for repair of large, superiorly based Schneiderian membrane perforations.
Methods: 11 patients undergoing sinus floor elevation augmentation via the lateral window approach, were diagnosed with a superiorly based, large (>1cm) membrane perforation. In order to correct the perforation, two small holes were made through the superior aspect of the bony window and the membrane was fixed with resorbable sutures through these holes. Next, a large (30*40mm) resorbable collagen membrane was inserted, following Xenograft filling, with or without dental implants.
A step by step procedure and literature review is presented.
Results: A total of 11 large perforations were treated via the described approach with no reported complications.
Conclusions: when thickness of the membrane and location of the perforations permit, anchoring the perforated membrane is an important tool in the surgical armamentarium. Fixing the membrane to bone, achieves integrity, thus, enabling to minimize secondary complications and maintaining the normal function of the sinus.
