Insights
Pediatric middle ear cholesteatoma, often causing hearing loss, requires early diagnosis and treatment. Optimal outcomes for children with cholesteatoma are achieved through early intervention and open tympanoplasty.
Area of Science:
- Otolaryngology
- Pediatric Otology
- Medical Research
Background:
- Cholesteatoma of the middle ear in children can lead to hypoacusis (hearing loss).
- Early diagnosis and effective treatment are crucial for achieving favorable functional results.
- This study reviews a cohort of pediatric patients treated for middle ear cholesteatoma.
Purpose of the Study:
- To analyze the clinical characteristics, treatment modalities, and outcomes of middle ear cholesteatoma in children.
- To evaluate the effectiveness of different surgical approaches and identify factors influencing treatment success.
- To highlight the importance of early detection and intervention in managing pediatric cholesteatoma.
Main Methods:
- Retrospective analysis of 57 children (58 ears) diagnosed with middle ear cholesteatoma between 1991 and 2002.
- Data collected included patient age, cholesteatoma type (acquired vs. congenital), location, presenting symptoms, audiological evaluation (air-bone gap), bacteriology, imaging findings, surgical procedures, complications, and recurrence rates.
- Surgical interventions included radical surgery, modified radical mastoidectomy, and tympanoplasty.
Main Results:
- The majority of cases were acquired cholesteatoma (89.6%) in children aged 11-15 years.
- Hearing loss (98.3%) and purulent otorrhea (85.4%) were the most common symptoms.
- Post-treatment, mean air-bone gap improved in acquired cholesteatoma (18.7 dB to 15.7 dB) but showed minimal change in congenital cases (13.6 dB to 14 dB).
- Complications included intracranial (2), intratemporal (2), and extracranial (1).
- Purulent otorrhea was the most frequent failure (36.2%), and reoperation for recurrence was performed in 29.3% of cases.
- Improved or stable hearing was achieved in 60.3% of ears.
Conclusions:
- Middle ear cholesteatoma in children presents diagnostic and therapeutic challenges due to its insidious onset, aggressive growth, and high recurrence rate.
- Early clinical detection and management, particularly with open tympanoplasty procedures, are associated with the best treatment outcomes.
- Aggressive surgical management and close follow-up are essential for minimizing complications and recurrence in pediatric cholesteatoma.
Abstract:
Cholesteatoma of the middle ear in children may cause hypoacusis. Early diagnosis and optimal treatment is neccessary for good functional effect. We present 57 children (58 ears) with cholesteatoma treated in ENT Department of Medical University in Gdańsk in 1991-2002. The age of patients ranged between 3 and 16 years, the most common 11-15 years. In 52 (89.6%) cases acquired cholesteatoma and in 6 (10.4%) congenital cholesteatoma was diagnosed. Epitympanal cholesteatoma was found in 32 children (55.1%) whereas in posterior part of tympanic cavity--in 20 children (34.5%). In 6 cases (10.4%) intact tympanic membrane was found. Mean air-bone gap in acquired cholesteatoma before treatment was 18.7 dB, after treatment 15.7 dB. In congenital cholesteatoma mean air-bone gap before treatment was 13.6 dB, after treatment 14 dB. The most frequent symptom was hearing loss (98.3%) and purulent otorrhea (85.4%). Positive bacteriological culture was obtained in 43.1% of the cases. X-ray revealed sclero-pneumatic mastoid in 26 (34.5%) cases, sclerotic in 25 (43.1%) and pneumatic mastoid in 7 (12.1%) cases. Intracranial complications were found in 2 cases, intratemporal in 2 cases and extracranial complication in 1 case. Radical surgery was performed in 23 cases (39.7%) and in each case, which required reoperation, modified radical mastoidectomy in 20 cases (34.4%), in another 15 children (25.9%) tympanoplasty was done. The most frequent failure was purulent otorrhea in 21 (36.2%) cases. Reoperation in cholesteatoma recurrence was performed in 17 children (29.3%). Improvement or the same as preoperatively hearing level was obtained in 35 (60.3%) ears, hearing loss was revealed in 23 (39.7%) ears. Treatment of temporal bone cholesteatoma in children is difficult due to silent beginning, aggressive growth and frequent recurrence. The best treatment results in children cholesteatoma are obtained in early clinical stage and with open tympanoplasty procedure.
