This is a novel minimally invasive surgical method for maxillary sinus mucoceles and antrochoanal polyps.

To describe a modified technique of inferior meatal fenestration with a mucosal flap for maxillary sinus diseases and to present a case series of subjects who underwent this procedure. The novel surgical technique and indications for this approach are also discussed.

Material and Methods
The authors analyzed data from 32 cases involving patients who underwent resection of maxillary sinus mucoceles and antrochoanal polyps via modified endoscopic inferior meatal fenestration with a mucosal flap in the period from January, 2011 to January, 2016. The group included 19 men and 13 women, and the patients’ mean age was 36.2 years (range: 11–56 years). Preoperative and postoperative imaging studies were available in all cases and were reviewed.

Thirty-two cases are included in this study. The appearance of nasal and (or) maxillary sinus mucosa was observed in the follow-up at 1 month, 3 months and 6 months using endoscopes. Postoperative computed tomography was performed for only 9 patients in this study. The mean follow-up period was 56 (range: 10–82) months in these cases. All patients had an uneventful post-operative period. Postoperative symptoms were relieved gradually for 1 to 2 weeks after the operation. No patients experienced recurrent symptoms related to the mucocele. Mucocele and polyps recurrence was not observed. No patient showed re-stenosis and obstruction of the nasal cavity, facial pain or numbness during follow-up.

Maxillary sinus mucoceles and antrochoanal polyps are completely excised via modified endoscopic inferior meatal fenestration with a mucosal flap. It could keep the nasal lateral wall intact.
