Summary
Transcanal tympanoplasty is effective for chronic suppurative or atelectatic otitis. Hearing outcomes were similar between these conditions, but malleus handle destruction impacted results.
Area of Science:
- Otolaryngology
- Surgical Innovation
- Otologic Surgery
Background:
- Chronic suppurative otitis and atelectatic otitis present distinct clinical characteristics.
- Understanding the efficacy and long-term outcomes of surgical interventions for these conditions is crucial.
Purpose of the Study:
- To evaluate the efficacy, safety, and long-term stability of transcanal tympanoplasty.
- To compare surgical outcomes between chronic suppurative otitis and atelectatic otitis.
- To identify factors influencing hearing results and complications.
Main Methods:
- Transcanal tympanoplasty using connective tissue underlay grafts and ossicular bone prostheses.
- Avoidance of mastoid exposure unless irreversible disease is present.
- Analysis of hearing results, long-term stability, and complications over a one-year observation period.
Main Results:
- Transcanal tympanoplasty met contemporary standards for chronic suppurative otitis and atelectatic otitis.
- No significant differences in ossicular destruction, surgical response, hearing outcomes, or complications were found between the two otitis types.
- Poorer hearing results were observed in patients with malleus handle destruction using L-shaped prostheses.
Conclusions:
- Transcanal tympanoplasty is a viable surgical option for chronic suppurative otitis and atelectatic otitis.
- Malleus handle destruction necessitates alternative surgical approaches, potentially involving homograft tympanic membranes.
- A one-year observation period is statistically suitable for assessing surgical outcomes in these patient groups.
