舌骨下肌皮瓣修复口腔颌面缺损的应用解剖

Applied Anatomy of the Infrahyoid Myocutaneous Flap for Repairing Oral Maxillofacial Defects

目的:为口腔颌面恶性肿瘤切除后采用舌骨下肌皮瓣修复的手术方式提供应用解剖学依据。方法:对40具(80侧)头颈部标本的舌骨下肌群的形态特征,血管神经支配进行观测。结果:舌骨下肌群各肌厚度均较薄,供应动脉为甲状腺上动脉,回流静脉为甲状腺上静脉,舌骨下肌群的神经支配来自颈襻分支。结论:该肌群修复口腔颌面缺损形态学有可行性,以舌癌切除后舌再造修复效果较好,制备肌皮瓣时应在肌外缘切取,可制成神经血管蒂保留转移肌肉功能,减少日后萎缩。

Objective:To provide anatomical data for repairing oral maxillofacial defects with infrahyoid myocutaneous flap resection of malignant tumor.Methods:The morphology,blood vessle,and nerve of infrahyoid muscles(40 cases or 80sides)were studied and measured by cephalocevical sample dissection.Results:There are suitable thickness of infrahoid muscles,blood supply is from the superior thyroid artery.venous return of infrahyoid muscles is the superior thyroid vein.Conclusion:The infrahyoid muscles is suitable for repairing oral maxillofacial defects.effect of lingual reconstruction is better.When preparing the myocutanous flag for repair operation,care must be taken that the muscles should be cut from the outer part of it,to prevent atrophy muscles nerve vascular pedicle was made.
