口干症是头颈部肿瘤放疗后常见的后遗症。如何预防口干症的发生,有人设想在放疗前把涎腺组织移植到放射野外的“安全区”,如口腔前庭粘膜下,以保留其分泌唾液的功能。作者进行了动物实验研究,以了解涎腺移植后是否能够成活,是否具有分泌功能,会不会并发粘液囊肿等。 材料和方法 24只Syrian仓鼠分成两组,一组12只为颌下腺移植组,另一组12只为腮腺移植组。动物全麻下局部脱毛,体位固定,常规消毒后作颈部
Dry mouth is a common sequelae of head and neck cancer after radiotherapy. How to prevent the occurrence of xerostomia, it was envisaged in the radiotherapy salivary gland tissue transplanted to the radiation field outside the “safe area”, such as the oral vestibular mucosa to retain the function of saliva secretion. The authors conducted animal experimental studies to understand whether salivary gland transplantation can survive, whether it has a secretory function, will not be complicated by mucous cysts. MATERIALS AND METHODS Twenty-four Syrian hamsters were divided into two groups, one 12 for the submandibular gland graft group and the other 12 for the parotid gland graft group. Local anesthesia under local hair removal, fixed position, routine disinfection for the neck
