喉部分切除术后喉囊肿

Laryngeal cyst after partial laryngectomy

目的探讨喉部分切除术后喉囊肿的发病率、病因、临床特点、诊断及治疗方法。方法回顾性分析2003年1月～2009年6月北京同仁医院收治的228例颈外入路喉部分切除术患者的诊疗及随访情况,并对喉部分切除术后喉囊肿进行分析报道。结果随访中发现2例喉囊肿,均为喉部分切除会厌成形术后。1例于术后20个月发现囊肿位于会厌舌面,行支撑喉镜下CO2激光切除囊肿。另1例术后19个月发现囊肿位于声门下区,经颈外入路切除。结论喉部分切除术后喉囊肿并不常见,可能与会厌前间隙分离过程中黏膜上皮种植有关。CT或MRI有助于诊断。囊肿可于支撑喉镜下或经颈外入路行手术切除。

OBJECTIVE To study the incidence,pathogenesis,diagnosis and treatment of laryngeal cyst after partial laryngectomy.METHODS The clinical data of 228 cases of partial laryngectomy from January 2003 to June 2009 were retrospectively analyzed,and related literature was reviewed.RESULTS Two cases were found to have laryngeal cysts after partial laryngectomy during the post-operative follow-up.One occurred after 20 months,and the other occurred after 19 months.The cyst located on the tongue surface of the epiglottic was removed by CO2 laser under suspended laryngoscope,while the one located at the subglottic area was removed via cervical approach.So far,a total of 9 cases were reported.CONCLUSION Laryngeal cyst after partial laryngectomy is uncommon.That may be the mucosa planted during the operation.It could be misdiagnosed as recurrent laryngeal carcinoma.CT or MRI is helpful for diagnosis.Operation with CO2 laser under suspended laryngoscope or via cervical approach may be chosen.
