Background:
Sinonasal inverted papilloma (SNIP) is a benign tumor that can be surgically managed by an endoscopic approach. However, SNIP has a high recurrence rate, mainly due to incomplete resection.
Aim:
This study aimed to analyze the outcomes of endoscopic modified medial maxillectomy in treating SINP originating from the maxillary sinus.
Methods:
The authors retrospectively analyzed 24 patients treated for SNIP via endoscopic modified medial maxillectomy at our institution between August 2014 and June 2019. During surgery, the mucosa involved in the tumor was stripped, and the bone underlying the tumor base was completely excised. Demographic data, surgical technique, location of SNIP attachment, complications, follow-up duration, and recurrence were recorded.
Results:
Twenty four patients with SNIP were identified (16 males). All patients had Krouse stage-III disease. Eleven patients presented with single attachment and 13 with multiple attachments. None of the patients had any complications during surgery. Four patients had postsurgical facial numbness around the cheek and upper lip. After a mean follow-up of 35.12 ± 14.98 months, no recurrence of SNIP was observed.
Conclusions And Significance:
Endoscopic modified medial maxillectomy is a safe and effective technique for treating SNIP. Recurrence can be reduced by complete excision of the attachment sites.
