The treatment of external auditory canal (EAC) stenoses often requires the prolonged use of a stent or splint. Traditional stents often occlude the EAC, resulting in a temporary conductive hearing loss. This case report describes a custom canal earmold with a large bore used as a stent in a patient with EAC stenosis. The customized earmold stent successfully prevented restenosis, while the large bore provided ventilation and improved hearing subjectively during the stenting phase. El tratamiento de la estenosis del conducto auditivo externo (EAC) a menudo requiere del uso prolongado de un stent o una férula. Los stents tradicionales a menudo ocluyen el EAC, provocando una hipoacusia conductiva temporal. Este reporte describe un caso un molde auditivo hecho a la medida con un agujero grande utilizado como stent en un paciente con estenosis del EAC. El stent de molde auditivo a la medida fue exitoso en prevenir la re-estenosis, mientras que el gran agujero aportó ventilación y mejoró subjetivamente la audición durante la fase de mantenimiento del stent.

Cholesteatomas are found almost exclusively in the middle ear and mastoid. Occasionally this disease is seen in the external auditory canal. Cholesteatoma of the external auditory canal is a rare condition. Severe pain and profuse discharge associated with a normal eardrum and normal hearing are essential clinical features. In addition, we found facial paresis and conductive hearing loss in our case. Smaller cholesteatomas can be managed by frequent debridement in the office; larger lesions require surgical intervention. Surgery is successful in resolving otorrhea and relieving pain. In addition, our own experience has shown that surgery is successful in relieving facial paresis.

Air Conduction

Introduction The tone-evoked auditory brainstem responses (tone-ABR) enable the differential diagnosis in the evaluation of children until 12 months of age, including those with external and/or middle ear malformations. The use of auditory stimuli with frequency specificity by air and bone conduction allows characterization of hearing profile. Objective The objective of our study was to compare the results obtained in tone-ABR by air and bone conduction in children until 12 months, with agenesis of the external auditory canal. Method The study was cross-sectional, observational, individual, and contemporary. We conducted the research with tone-ABR by air and bone conduction in the frequencies of 500 Hz and 2000 Hz in 32 children, 23 boys, from one to 12 months old, with agenesis of the external auditory canal. Results The tone-ABR thresholds were significantly elevated for air conduction in the frequencies of 500 Hz and 2000 Hz, while the thresholds of bone conduction had normal values in both ears. We found no statistically significant difference between genders and ears for most of the comparisons. Conclusion The thresholds obtained by bone conduction did not alter the thresholds in children with conductive hearing loss. However, the conductive hearing loss alter all thresholds by air conduction. The tone-ABR by bone conduction is an important tool for assessing cochlear integrity in children with agenesis of the external auditory canal under 12 months.

Keratosis obturans is characterized by the accumulation of desquamated keratinous material in the bony portion of the external auditory canal. Classically, it is reported to present with severe otalgia, conductive hearing loss and global widening of the external auditory canal. Extensive erosion of the bony meatus, with exposure of the facial nerve, has been previously reported, but no case of facial nerve palsy has as yet been published. We report the first published case, to our knowledge, of a unilateral facial nerve palsy secondary to neglected keratosis obturans.

<p class="abstract">Neurofibromas are relatively common tumours of the nervous system, but only few cases involving the external ear have been reported. We are reporting here a case of a 30-year-old male with neurofibroma of the external auditory canal. The primary complaint was cosmetic deformity and mild conductive hearing loss. There was total occlusion of the external auditory canal. The swelling was excised by postauricular approach. Surgery resulted in an superb purposeful and cosmetic outcome. Neurofibromas of the head and neck do not seem to be uncommon, however they seldom have an effect on the external ear and only a few such published reports are available.</p>
