Prognosis of closure of large sinus membrane perforations using pedicled buccal fat pads and a resorbable collagen membrane: case series study

Abstract

For large membrane perforations that develop during sinus-bone grafting, we performed repairs using a pedicled buccal fat pad and a resorbable collagen membrane simultaneously with the bone graft. This study included eight patients. Postoperative maxillary sinusitis developed in two patients, which we managed with incision and drainage, and antibiotics. Ultimately, six patients received 12 implants, three of which failed (75% success). Implant replacement was performed after the removal of the failed replacement, at which point the prosthetic treatment was considered complete. In all of the six cases that we were able to follow-up with, the sinus-bone graft was healing favorably. We observed that the sinus bone height decreased gradually with time. Based on these case series, we conclude that our procedure of repairing large sinus-membrane perforations with a pedicled buccal fat pad and a collagen membrane is a reliable technique.

“…To close perforations of the Schneiderian mucosa, it has been suggested to apply resorbable membranes between the sinus mucosa and the grafting material (Pikos 1999;Proussaefs et al 2003;Testori et al 2008;Kim et al 2014). These authors suggested that the placement of a collagen membrane may, indeed, lead to a higher bone fill of the sinus cavity, even though no randomized controlled studies have substantiated such claims.…”
