서종천(Jong Cheon Seo),김종렬(Jong Ryoul Kim),양동규(Dong Kyu Yang) 대한구강악안면외과학회 1996 대한구강악안면외과학회지 Vol.22 No.1
This study was undertaken to investigate the changes of maximum bite force, range of mouth opening, and muscle activity in EMG after orthognathic surgery. The maximum bite force, range of mouth opening, and muscle activity in EMG were measured in 20 dentofacial deformity patients, aged 19-38(mean age 23.95) years, before surgery and at 2, 3 and 6 months after surgery. These patients were divided into three groups according to operation methods, that is 3 in IVRO group, 8 in BSSO group, and 7 in two-jaw surgery group. Thereafter the recovery of maximum bite force and the effect of duration of intermaxillary fixation were assessed. The results, were as follows. 1.The presurgical maximum bite force was 12.13 kg in upper first molar(Lt. Side 12.15kg, Rt. side 12.15kg respectively). being much lower than that of normal occusion, and maximum mouth opening was 48.45mm, falling in the normal range. 2. Maximum bite force and mouth opening were much increased 3 months after surgery in BSSO group and 3 months to 6 months after in IVRO and two-jaw surgery groups. 3. Muscle activity in EMG during maximal bite was lower than that of normal occlusion and approaching to the presurgical value or above at follow up examination 6 months after surgery. 4. It takes approximately 6 months after surgery for the bite force to recover to its presurgical value.

The celvical flap, comprising skin, fascia, and platysma muscle, has significant application in the head and neck region after radical ablative surgery for cancer of the oral cavity. The flap may be used for recon-struction of the cheek, floor of the mouth, and lateral side of the tongue. This flap minimizes donor morbidity by use of cervical operation wound and flap size available is adequate for most oral defects and the procedure is relatively simple and time-saving. However the flap is not applicable in patients where there are large tissue defects and metastasis is suspected. We have used the celvical flap for its rapid, simple, and effective closure of oral defects after cancer ablation and found it is very useful for the reconstruction of relatively small oral defects.

Various cutaneous as well as myocutaneous flaps have been designed for the reconstruction of tissue defects caused by the excision of oral cancer. Among these flaps, cervical island skin flap have been introduced by Farr et al and more have developed by Tashiro et al. This flap has many advantages. The flap minimizes donor size by use of cervical operation wound, flap size available is adequate for most oral defects and the procedure is relatively simple and time saving. However, this flap is not applicable in patients where there are large tissue defects and metastasis is suspected. We used this flap for it's rapid simple, and effective, primary closure of oral defects after cancer ablation and we have found this flap very useful for the reconstruction of relatively small oral defects.
