<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>

Conductive Hearing

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.

AbstractA case of bilateral progressive stenosis of both external auditory canals with resultant conductive hearing loss is presented. The stenosis revealed multifocal erosive and synechiant lichen planus. To our knowledge, this is the first reported case of lichen planus involvement of the external ear.

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.

ABSTRACT Introduction Radiotherapy either primary or adjuvant, is a commonly used modality of treatment in head and neck malignancies. The audiovestibular apparatus is often within the fields of radiation treatment, and hearing loss is a possible complication. This study was undertaken to assess the audiovestibular functions in patients undergoing radiation therapy for head and neck malignancies to determine the type and severity of hearing loss and vestibular dysfunction following radiation therapy. Materials and methods Fifty patients with head and neck malignancies reported to the malignant disease treatment center of INHS Asvini and received radiotherapy as a primary modality of treatment or in combination with surgery during the period May 2003 to Sep 2004 were included in this study. None of these patients had prior treatment by chemotherapy. Conclusion A significant number of patients who were subjected to radiation therapy for head and neck malignancies develop conductive hearing loss is predominant in the immediate postradiation period. Conductive hearing loss is reversible and improves with the conservative line of treatment. Sensorineural hearing loss more commonly affects the higher frequencies and is more common in older patients. Sensorineural hearing loss is more common when radiation doses exceed 60 Gy. There is no conclusive evidence of vestibular dysfunction in patients undergoing radiotherapy for head and neck cancers.

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.
