Sinus obliteration for chronic oro-antral fistula: a case report

This report describes a patient with chronic oro-antral fistula resulting from tooth extraction. Several local flap procedures failed to close the fistula, which was complicated by chronic sinusitis. Ultimately, cure was achieved via antral obliteration using vascularised temporoparietal fascia, sparing remaining maxillary alveolar bone. Total, trans-buccal maxillary sinus obliteration with fascia should be considered for the treatment of oro-antral communications refractory to treatment with intraoral tissues.
