阻塞性睡眠呼吸暂停综合征患者的颌下腺研究

To Research Submandibular Gland of the Obstructive Sleep Apnea Syndrom.

目的探讨阻塞性睡眠呼吸暂停综合征(obstructive sleep apnea syndrome,OSAS)患者的颌下腺。方法回顾46例摘除颌下腺治疗OSAS的颌下腺资料,包括患者颌下腺病史综合与体检,以及颌下腺影像学研究,术中观察到的颌下腺形态和走向、体积测量,病理学检查,并与正常颌下腺进行对照,研究探讨OSAS患者的颌下腺。结果症状:46例患者均有咽喉部紧缩梗阻感,常有呼吸不畅,睡眠时打鼾,憋气;口底颌下区两侧触及颌下腺肿大,质地均匀较软;影像学:CT和MRI均显示颌下腺在下颌骨下缘以下;颌下腺最小者长度为3.5cm,宽3cm。体积:24～40cm3;病理检查:排除肿瘤,腺泡细胞测量直径均值为:58.56μm。结论OSAS患者均有颌下腺向下移位并肿大,即颌下腺下垂,是一种病变。

Objective To investigate the submaxillary gland with Obstrutive Sleep Apnea Syndrome （OSAS）. Methods To re- member46 data of the submaxillary gland of OSAS wicth it Extirpated the submaxillary gland to charm off OSAS,include symptoms and body, s syptoms, as well as imageologe, study , the pattern of the submaxillary gland , volumes of tfe submaxillary gland and pathologic di- agnosis. Results Symptoms： On 46 patients of OSAS ,to have sensation of narrow - contract and block on the throat,ofen to have less unblocked on breathe,to snoring and OSA on sleep; body, s syptoms ：the Submandibular Gland is displacement to down and swollen, natuye piece is softer, imageologe： this case all to examined the pharynx by spirad CT or MRI. All case displaied the submaxillary gland below inferior edge of the mandible, smallest submandibular gland ： length - 3.5 cm, breadth - 3.0cm ; volumes of tfe submaxillary gland ： 24 -40cm3 ; pathologic diagnosis： this case alle were liminated tomour,the mean of the acinar path is 58.56μm. Conclusion 46 patients of OSAS all are that is the submaxillary gland wich displacement down and swollen, be near the Submandibular glan droop, it is patient, s condition.
