[Extended inferior meatal approach by reversing inferior turbinate for maxillary sinus and adjacent lesions].

The aim of this study is to explore the feasibility and results of surgical removal of maxillary sinus and adjacent lesions via extended inferior meatal approach by reversing inferior turbinate.Among these 28 cases,there were 9 cases of maxillary cysts(4 of which with oroantral fistula),2 cases of odontogenic maxillary sinusitis(1 of which with oroantral fistula),3 cases of maxillary sinus cysts,2 cases of antrochoanal polyps,5 cases of maxillary sinus inverted papilloma,1 case of maxillary sinus inverted papilloma with infiltrative squamous cell carcinoma(moderately differentiated),4 cases of inferior orbital fracture,1 case of anterior maxillary sinus wall fracture,and 1 case of infratemporal fossa cysts with fungal maxillary sinusitis.All operations were conducted via extended inferior meatal approach.All patients did not have intraoperative complications,and were free of recurrence after the 3 to 36 months postoperative follow-up.The extended inferior meatal approach by reversing inferior turbinate can deal with all aspects of the maxillary sinus and retromaxillary lesions.This procedure has a clear vision and high successful rate.
