초록
External auditory canal exostosis (EACE) is prone to occur in patients frequently exposed tocold water, which causes earwax impaction, recurrent otitis externa, and conductive hearingloss. The main treatment for symptomatic EACE is surgical excision. External auditory canalcholesteatoma (EACC) is a bone-destructive cystic mass caused by accumulation of plugs ofdesquamated keratin debris in the external auditory canal (EAC), which is also mainly treatedwith surgical removal. The main difficulties in the surgical removal of obstructive EACEs orEACCs are related to the adjacency of EAC skin, tympanic membrane, temporomandibularjoint, and the blockage of the medial EAC landmarks during the operation. The piezoelectricdevice (PZD), which has long been used to cut bony structures in dental surgery, has clinicaladvantages here with regards to accurate exclusive bone cutting ability and minimal heat production. We report a series of cases that managed EAC lesions using PZD.
