Progressive hearing loss in a rare case of ceruminous pleomorphic adenoma of the external auditory canal

We report the case of a patient who came to us for evaluation of a progressive unilateral hearing loss and who was found to have a sebaceous nevus in an unusual location: the external auditory canal. A sebaceous nevus is a congenital organoid mass that occurs primarily on the face, scalp, and periauricular regions. Despite the predilection of sebaceous nevi for the head and neck, reports of this lesion rarely appear in the otolaryngology literature. Left untreated, the lesion can progress through three stages of gross and histopathologic development; a sebaceous nevus begins as a small benign papule, grows into an enlarging mass with different characteristics, and ultimately becomes a secondary neoplasm. The lesion's potential for malignant transformation and its association with syndromes underscores the importance of prompt recognition and appropriate management. This case report adds the sebaceous nevus to the differential diagnosis of external auditory canal lesions and provides essential information about this rare mass.

Progressive Hearing Loss

AbstractAlthough exostoses of the external auditory canal are not uncommon, those of the internal canal are extremely rare. One of these is described occurring in a 53-year-old man whose rapidly progressive hearing loss was without any associated abnormality.

Herniation of the tympanic membrane is a rare benign malformation of the tympanic membrane into the external auditory canal. It may be asymptomatic or associated with symptoms such as aural fullness, tinnitus, otalgia or hearing loss. We present a case of a symptomatic herniation of the tympanic membrane and its surgical therapy with hernia excision and tympanoplasty. An internal review board exemption was obtained.

Hearing Outcome

Objective: The aim of this study was to evaluate hearing outcome after stapedotomy in patients with Otosclerosis. Methods: This cross sectional study was carried out from July 2017 to January 2019 in National Institute of ENT, Unit V. About 22 patients with Otosclerosis were included in this study. Diagnosis of Otosclerosis was based on the history, medical status with Otoscopy, Tuning fork tests and Audiometric tests. We compiled data on the pre and post operative air-bone gap (ABG) at 0.5, 1, 2 KHZ. The ABG was Calculated using AC and BC thresholds on the same audiogram. Post operative hearing gain was then Calculated from the ABG before the operation minus the ABG of the last follow up examination Results: In this study most of the cases were age group 14-30 years (72.7%), female (54.5%). Most common symptoms was progressive hearing loss, tinnitus (77.8%).The average preoperative hearing loss in this study was (AC) was 48.31±7.68. The average post opt. hearing (AC) at follow up was 28.95±10.30 with an average hearing gain of 15.40±8.53 dB which was significant. The average pre-operative ABG was 28.99 dB ± 8.10. The average post opt. ABG was analyzed at 1 follow up showed ABG 13.18±8.09 dB which was found to be significant. Conclusion: Stapedotomy is an effective surgical procedure for the treatment of otosclerosis which leads to improvement in patient’s quality of life. A favorable hearing outcome can be obtained by the combination of experienced hands with minimal surgical trauma and appropriate surgical technique.
