Abstract
ObjectiveTo investigate the method in treatment of Eustschian tube atresia caused by radiotherapy.
MethodsTwo cases diagnosed of Eustschian tube atresia following radiotherapy were retrospectively analyzed in Department of Otorhinolaryngology, Divided Hospital of Shanghai University Communication Affiliated First People Hospital in Apr. 2014 and Oct. 2015. Both cases were female, 65 and 64 years old, and accepted radiotherapy six and 20 years ago respectively. The pharyngeal orifices of Eustschian tube were found to be totally closed under endoscope. The closed Eustschian tubes were re-opened by laser and re-shaped by a slim and conical plastic tube for more than six months. They were followed up and evaluated over 12 months.
ResultsAt six and 12 months after treatment, round mouths were formed in the pharyngeal orifice of Eustachian tube, and the patients had no resistance in Valsalva′s test. No shrink or abnormal opening of orifice was found at follow-up of 20 and 12 months.
ConclusionThe method of re-opening by laser and re-shaping by a slim and conical plastic tube is recommended to treat Eustschian tube occlusion caused by radiotherapy.
