総論③ 局在診断に基づいた頬部の腫瘍に対する手術アプローチ法

Surgical Approach to Cheek Tumors Based on Localization

はじめに

　頬腫瘍に対する手術では，腫瘍の局在と顔面神経やステノン管との位置関係を把握することが重要な鍵となる。今回，われわれは頬部に生じた皮下腫瘍の2例を提示し，頬部の解剖学的特徴および腫瘍の局在に基づいた手術アプローチ法の選択について述べる。

　A tumor of the cheek is a relatively common disease encountered in daily clinical practice. In surgeries for buccal tumors, it is essential to identify the location of the tumor and its anatomical relationship to the facial nerve and Stensen’s duct. The presence of an accessory parotid gland should also be considered in subcutaneous tumors arising in the central cheek region. The surgical approaches to the cheek region include a direct incision over the mass, a facelift-based incision, and an S-shaped incision, the uses of which vary from one institution to another.

　In this report, we present two cases of subcutaneous tumors in the cheek region and describe the selection of the surgical approach to cheek tumors based on the localization of the tumor, as well as the precautions that should be taken.
