    Abstract:
    INTRODUCTION: This is a novel minimally invasive surgical method for maxillary sinus mucoceles and antrochoanal polyps. AIM: 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. RESULTS: 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. CONCLUSIONS: 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.
