Retrospective audit of sinonasal inverted papilloma at a tertiary care centre

Somu L., Prasanna Kumar S., Urvashi Singh

Abstract


Background: Inverted Papilloma of the sinonasal tract is a benign neoplasm with unique locally destructive capacity, tendency to recur and a propensity for malignant change. Despite varied studies, there seems to be a lack in consensus with regards to its etiology, predictors of recurrence and malignant transformation. The aim of our study is to analyse the clinical profile, management and outcome of histopathologically proven Inverted Papilloma of the nose and paranasal sinus at our institute.

Methods: Retrospective chart review of 17 patients of histologically proven Sinonasal Inverted Papilloma over a period of 2 years from May 2013 to May 2015.

Results: The majority were in their 5th and 6th decade of life (47%) with a male to female ratio of 15:2. All had been managed surgically with 10 patients undergoing endoscopic assisted polypectomy, 6 requiring partial maxillectomy & 1 requiring total maxillectomy for complete surgical clearance. All patients had been followed up for a minimum duration of 1 year and recurrence was found in 41%. 2 patients had been diagnosed with malignant transformation during follow-up, out of which 1 underwent right partial maxillectomy along with concurrent chemotherapy and other patient underwent left total maxillectomy with concurrent chemotherapy and intensity modulated radiation therapy.

Conclusions: Inverted Papilloma of the sinonasal tract is a locally aggressive disease requiring careful endoscopic and radiological assessment. Adequate surgical management can ensure complete clearance of disease. A strict long term follow-up protocol will facilitate identifying recurrence and malignant transformation.
