Summary
A rare bilateral congenital external auditory canal anomaly led to lifelong cholesteatoma in a patient. Despite decades of disease, crucial structures remained intact, but hearing loss was profound.
Area of Science:
- Otorhinolaryngology
- Medical Diagnostics
- Surgical Pathology
Background:
- A patient presented with a 24-year history of recurrent infra-auricular fistulation, initially treated for suspected parotitis or lymphadenitis.
- Previous diagnostic workup lacked detailed sonographical or radiological assessments.
- No severe complications such as meningitis or labyrinthitis were reported during the initial treatment phases.
Observation:
- Bilateral genuine cholesteatoma was identified, associated with anomalies of the external auditory canal.
- The external ears (auriculae) appeared normally formed.
- Radical corrective surgery was performed sequentially on both sides.
Findings:
- Remarkably, a cholesteatoma present for over two decades did not erode the bony boundaries of the middle ear, labyrinth, cochlea, or facial canal.
- The patient exhibited a severe degree of hearing loss.
- Intraoperative acoustic potentials were unobtainable, indicating deafness, with the etiology (congenital vs. acquired) undetermined.
Implications:
- This case highlights the potential for extensive cholesteatoma development without adjacent bony erosion.
- The findings underscore the importance of advanced imaging in diagnosing external auditory canal anomalies and associated cholesteatoma.
- Further investigation is needed to understand the long-term effects of such anomalies on hearing and to determine the precise cause of deafness.
