Laryngeal cyst after partial laryngectomy / 中国耳鼻咽喉头颈外科

ABSTRACT

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.
