The use of vascularized bone grafts, which has recently been enabled, has improved bone graft survival rates, and its combination with dental implants has enabled both morphological and functional reconstruction, leading to a higher quality of life.
We experienced two patients with tumors of the jaw that were treated by resecting and reconstructing it using a vascularized bone graft with the cooperation of the Department of Plastic Surgery in the School of Medicine. We subsequently inserted dental implants, and the superstructure was created by the Department of Prosthetics. We report the course of these patients, who achieved sufficient jaw morphology as well as masticatory function and who are presently satisfied overall three years to three years and nine months postoperatively.No potential conflict of interest relevant to this article was reported.岡山医学会Acta Medica Okayama0030-155812032008頭頸部癌における頭頸部外科，形成外科，口腔外科３科合同手術における口腔外科の役割：下顎再建症例における３Ｄ石膏造形モデルを利用した術前プレート屈曲法299305ENNobuyoshiMizukawaSusumuTominagaYoshihiroKimataTomooOnodaNarushiSugiyamaEikiYamachikaYousukeYamadaTakujiKimuraTetsuoTakeuchiTakaakiUenoShinTakagiThe collaboration of various medical teams is crucial for the appropriate treatment of cancer patients. However, in Japan, it is very difficult for oral surgeons to cooperate with head and neck surgeons due to conflicts in the treatment of those patients. There have been few studies on this subject. In the current work, we report on the collaboration of head and neck surgeons, plastic surgeons and oral surgeons in operations on two patients with gingival carcinomas in the mandible. We first prepared plaster 3D models of the patients'mouths by means of ink-jet from CT data. We pre-bent the reconstruction plates using the preoperative 3D models. Therefore, we could save the time required to bend the plate. Plaster models are cheaper than resin models. It is also easy to model the surgery using the plate. During the operation, head and neck surgeons resected the tumors, plastic surgeons performed reconstruction with vascularized bone or skin graft, and oral surgeons (dentists) did plate fixation and took charge of the patients'occlusion. This method resulted in patients having good occlusion after the operation.No potential conflict of interest relevant to this article was reported.岡山医学会Acta Medica Okayama0030155811932008頭頸部癌における耳鼻咽喉科, 形成外科, 口腔外科3科合同手術の意義 : 2症例における口腔外科の役割を中心に267272ENNobuyoshiMizukawaSusumuTominagaYoshihiroKimataTomooOnodaShigenobuNomiyaNarushiSugiyamaTomoakiKawamotoEikiYamachikaTakaakiUenoShinTakagiThere is a medical team approach used in many hospitals for oral cancer patients. The members are head & neck surgeons and plastic surgeons, or oral surgeons and plastic surgeons. However, in Japan, it is very difficult for oral surgeons to cooperate with head & neck surgeons, except in the case of extractions and oral health care, because both surgeons treat oral carcinomas and there is therefore a conflict in their scope of practice. We believe it desirable for head & neck surgeons to treat oral cancer patients with tumors extending to other regions, and oral surgeons should be in charge of occlusion in head and neck carcinomas. We treated two patients with oral carcinomas in collaboration with head and neck surgeons and plastic surgeons, with head & neck surgeons resecting the tumors, plastic surgeons reconstructing, and oral surgeons (dentists) taking charge of the occlusion for patients in the operating room. This collaboration resulted in patients having good position of the temporomandibular joint and occlusions after the operation. We therefore conclude that this collaborative team approach may be of benefit to the patients.No potential conflict of interest relevant to this article was reported.Acta Medica Okayama1982家兎脛骨骨膜遊離移植に関する実験的研究ENNo potential conflict of interest relevant to this article was reported.
