Insights
Tympanostomy tube insertion in children is generally safe, with low rates of otorrhea and no cholesteatoma cases. Hearing improved in most patients, though tympanosclerosis was common.
Area of Science:
- Otolaryngology
- Pediatric Surgery
Background:
- Tympanostomy tube insertion is a common otolaryngologic procedure.
- Potential complications include otorrhea, tympanosclerosis, and cholesteatoma.
Purpose of the Study:
- To report complications and hearing outcomes following tympanostomy tube insertion in children.
- To analyze the incidence of various complications and long-term results.
Main Methods:
- A retrospective study of 239 children (439 ears) undergoing tympanostomy tube insertion.
- Follow-up ranged from 7 to 73 months (median 29 months).
- Complications, hearing results, and middle ear pressures were assessed in 366 ears.
Main Results:
- Otorrhea occurred in 0.8% of cases; tympanosclerosis in 20.2%.
- Other complications included tympanic membrane perforation (4.6%), retraction pockets (5.2%), granulation tissue (1.1%), and atelectasis (6%).
- No cholesteatoma developed. Hearing improved in 93.4% of patients. Extrusion times varied for grommet and T-tubes.
Conclusions:
- Tympanostomy tube insertion yields good hearing outcomes with manageable complication rates.
- Otorrhea may be linked to multifactorial etiologies including underlying pathology or environmental factors like atopy.
Objective:
Tympanostomy tube insertion is one of the most frequently performed procedures in otolaryngology. Complications, such as otorrhea, tympanosclerosis, and cholesteatoma, have been reported in the literature after its application.
Study Design:
This study reports the complications encountered with 239 children (439 ears) with a follow-up of 7 to 73 months (median, 29 months) after tympanostomy tube insertion. Hearing results and middle ear pressures were compared and complications were noted in 366 ears that were available for the study.
Results:
Otorrhea developed in 3 (0.8%) cases. Tympanosclerosis was seen in 74 (20.2%) cases. Tympanic membrane perforation, retraction pocket, granulation tissue, and atelectasis were seen in 4.6%, 5.2%, 1.1%, and 6%, respectively. No patients developed cholesteatoma after tube insertion. Hearing results were improved postoperatively in 93.4% of patients (median, 14.2 dB) and worse in 6.6% of patients (median, 8.3 dB). The average extrusion time was 7.3 months for grommet and 16.3 months for T-tubes.
Conclusion:
Multifactor etiologies show some unsolved or misunderstood underlying pathology, or unmentioned environmental factor such as atopy due to rich flora and humidity might exist to consider in the pathophysiology of the otorrhea.
