| Abstract | Carcinoma of the mandibular gingiva is common and can more easily invade the mandibular bone compared with other head and neck cancers. Tumours that approach or involve the mandible usually require marginal resection or segmental resection of the mandible. Marginal mandibulectomy was not associated with worse prognosis than segmental mandibulectomy. However, these two conventional surgical methods lead to significant disability including loss of hard and soft tissues, impaired function of speech, swallowing and mastication. Rehabilitation can be difficult or impossible due to the distorted postsurgical anatomy. There are rare clinical studies on the surgical method for the mandibular gingival carcinoma in situ. In this study we introduce a modified surgical method, buccal partial mandibulectomy, focusing on how to keep the alveolar bone crest and lingual gingiva of the lesion in the largest extent for patients with mandibular gingival carcinoma in situ. Being more appropriate than traditional marginal or segmental mandibulectomy, the modified surgical method can not only ablate the whole tumour with negative margin in soft tissue, but also achieve higher quality of postoperative life without tumour recurrence during the longest follow-up time of more than 40 months. Buccal partial mandibulectomy can maintain the jaw continuity and make it possible to achieve an adequate prosthetic rehabilitation such as implant-fixed prothesis. |
