Surgical treatment of lesions involving the supplementary motor area: Clinical results of 12 patients

Abstract

Aim: Surgical resection of lesions involving the dominant supplementary motor area (SMA) may result in immediate postoperative motor and speech deficits which in most cases are reversible. We report 12 patients with frontal lesions involving the SMA and aim to analyse the clinical data and the correlation of neurological deficit with the extent of SMA resection.
