External auditory canal exostosis (EACE) is prone to occur in patients frequently exposed to cold water, which causes earwax impaction, recurrent otitis externa, and conductive hearing loss. The main treatment for symptomatic EACE is surgical excision. External auditory canal cholesteatoma (EACC) is a bone-destructive cystic mass caused by accumulation of plugs of desquamated keratin debris in the external auditory canal (EAC), which is also mainly treated with surgical removal. The main difficulties in the surgical removal of obstructive EACEs or EACCs are related to the adjacency of EAC skin, tympanic membrane, temporomandibular joint, and the blockage of the medial EAC landmarks during the operation. The piezoelectric device (PZD), which has long been used to cut bony structures in dental surgery, has clinical advantages 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.

Three patients with extensive keratosis obturans were treated during a 12-month period. One presented with an idiopathic sensorineural hearing loss and was found to have keratosis obturans in the contralateral, asymptomatic ear. The disease process had resulted in a horizontal semicircular canal fistula in what was now, effectively, the only hearing ear. The second patient had an extensive dehiscence of the tegmen tympani. The third presented with a facial palsy. An automastoidectomy cavity was present, with circumferential skeletonization of the descending facial nerve over a length of 1.5 cm and dehiscence of the temporomandibular joint and jugular bulb. All three patients were successfully treated by surgical formalization of their automastoidectomy cavities. They appeared to represent cases of keratosis obturans rather than external auditory canal cholesteatoma, on the basis of previously published reports.These complications and patterns of bone erosion have not previously been described in keratosis obturans. The third patient is believed to have the most extensive case of keratosis obturans yet described.

Objectives: Foreign bodies (FBs) in external auditory canal (EAC) can occur at any age but are especially common in children and adolescents. The aims of the study were to evaluate the clinical characteristics of EAC FBs in children and adolescents and to discuss their proper management. Methods: A retrospective medical chart review was performed on patients who were treated for EAC FBs in a tertiary referral center from January 2007 to December 2017. We investigated the parameters of age, sex, type of FB, sedation method, complications, and removal strategy. Results: Of 284 patients, 176 (62.0%) were male. Peak incidences were noted at the ages of 3 to 6 years and 17 to 18 years. The frequently observed FBs were insects, followed by air-gun pellets, cotton balls, marbles, and earrings. Forty-one (14.4%) EAC FBs were removed with the naked eye, while 243 (85.6%) were removed under microscope in the otolaryngology department. Of these patients, 23 (9.5%) were administered sedatives and 1 (4.1%) needed general anesthesia. During or after the removal procedure, 4 (15.5%) patients had complications of EAC abrasion or laceration (42, 14.8%), and tympanic membrane perforation (2, 0.7%). Conclusions: External auditory canal FB showed a distinct characteristic of incidence regarding age, related to removal strategies. Characteristics of FB must be considered for safe removal.
