AIM: The aim of this study was to define the types of endoscopic endonasal resection for sinonasal malignancies according to their origin and extension.
METHODS: Patients who underwent endoscopic endonasal surgery for the removal of malignant tumors of the nasal passages, paranasal sinuses, and the anterior cranial base between 2003 and 2010 were included in the study. Patients' data were collected retrospectively. Patients were grouped according to types of endoscopic tumor resection as follows: type I: en bloc resection, type II: resection of intranasal free part piecemeal and origin of tumor en bloc, type III: resection of intranasal free part and origin of tumor piecemeal with curative intent, and type IV: resection of intranasal free part and origin of tumor piecemeal with palliative intent or removal of tumor with positive margin. The follow-up period varied from 2 to 7 years (mean, 4.35 years).
RESULTS: Twenty patients were included in the study. Five patients underwent type I, 6 patients type II, 4 patients type III, and 5 patients underwent type IV resection. No local tumor recurrence was seen after types I, II, and III resections, whereas 2 patients (10%) with the type IV resection had a local recurrence. Distant metastasis was observed in 4 patients (20%) postoperatively (1 patient in type I, 1 patient in type III, and 2 patients in type IV resection). Disease-specific death was 15% (1 case in type I and 2 cases in type IV).
CONCLUSION: Classification of endoscopic tumor resection used in the present study may help preoperative planning.
