In the last six years, anterior mandibulotomy was used to approach tumours of the oropharynx and oral cavity in 39 cases. Twenty-six of these had primary lesions in the anterior two-thirds of the tongue. Eight cases had lesions in the base tongue, three in the cheek, and two in the tonsil. Twenty-six cases had T3 tumours, nine had T2 lesions, and four had T4 tumours. Twenty-five patients received post-operative radiotherapy. In 16 cases the mandibulotomy was combined with a marginal mandibulectomy. In 23 cases reconstruction was carried out using a pectoralis major myocutaneous flap. Adequate margins on histopathology obtained in all but eight patients. Bone-related complications occurred in only three patients, all of whom were previously irradiated. Thus the anterior mandibulotomy provides excellent exposure for oral and oropharyngeal tumours, with low complication rate, and avoidance of segmental mandibulectomy.
在过去六年中，39例口咽和口腔肿瘤患者采用了下颌前部切开术。其中26例原发灶位于舌前三分之二处。8例病变位于舌根，3例位于颊部，2例位于扁桃体。26例为T3肿瘤，9例为T2病变，4例为T4肿瘤。25例患者接受了术后放疗。16例下颌前部切开术联合了下颌骨边缘切除术。23例采用胸大肌肌皮瓣进行重建。除8例患者外，所有患者的组织病理学切缘均足够。仅3例患者发生了与骨相关的并发症，所有这些患者之前均接受过放疗。因此，下颌前部切开术可为口腔和口咽肿瘤提供良好的暴露，并发症发生率低，并避免了节段性下颌骨切除术。
