[Extended inferior meatal maxillary antrostomy through inferior turbinate reversing approach for maxillary lesions].

Objective: To explore the feasibility of the extended inferior meatal maxillary antrostomy through inferior turbinate reversing approach.

Methods: Eight patients underwent extended inferior meatal maxillary antrostomy through inferior turbinate reversing approach for maxillary sinus lesions. The indications, surgical management and outcomes of the surgery were presented.

Results: There were 2 cases of maxillary dentigerous cyst with oroantral fistula, 2 cases of antrochoanal polyp, 2 cases of maxillary sinus inverted papillomas, 1 case of odontogenic maxillary sinusitis with oroantral fistula, and 1 case of maxillary sinus mucocele. All patients underwent extended inferior meatal maxillary antrostomy through inferior turbinate reversing approach without intraoperative complication, with good access to the lesions. Complete resection could be achieved through this approach, no postoperative complications occurred except one patient had a delayed wound healing of inferior turbinate, all patients were free of recurrence with the average postoperative follow-up of 7.8 months (range 4-12 months).

Conclusion: The extended inferior meatal maxillary antrostomy through inferior turbinate reversing approach is recommended for some maxillary pathology owing to its good access to the lesions and complete resection.
