Abstract:
The clinical analysis of the patients after tympanic membrane reconstruction with the temporal muscle fascia has been conducted. The total number of 145 patients, operated at the Otosurgery Department Medical University of Lodz, was divided into 2 Groups. Group 1 (n = 75) patients with chronic otitis media (central perforation and mobile ossicular chain). The preoperative mean conductive hearing deficit of 20 dB was observed in all evaluated patients. After surgery a satisfactory hearing improvement was observed in 90% of the patients. Group 2 (n = 70) patients with the reconstructed postero-superior part of the tympanic membrance and if necessary external auditory canal wall reconstruction. The mean conductive hearing deficit of up to 30 dB was observed before the surgery. Postoperatively in 75% of patients the hearing improvement was observed as well as the satisfactory healing of fascia implant. The postoperative evaluation indicates a better hearing improvement after the myringoplasties with the prefascial lamina than in the myringoplasties performed in the traditional ways.
Insights
Tympanic membrane reconstruction using temporal muscle fascia shows significant hearing improvement in chronic otitis media patients. Myringoplasties with prefascial lamina technique yielded better results than traditional methods.
Area of Science:
- Otolaryngology
- Surgical Innovation
- Regenerative Medicine
Context:
- Chronic otitis media frequently leads to tympanic membrane perforations, impacting hearing.
- Surgical reconstruction of the tympanic membrane is crucial for restoring auditory function.
- Temporal muscle fascia is a viable graft material for tympanic membrane repair.
Purpose:
- To evaluate the clinical outcomes of tympanic membrane reconstruction using temporal muscle fascia.
- To compare the efficacy of myringoplasties with prefascial lamina versus traditional techniques.
- To assess hearing improvement and graft healing in patients undergoing tympanic membrane reconstruction.
Summary:
- A clinical analysis of 145 patients undergoing tympanic membrane reconstruction with temporal muscle fascia was conducted.
- Group 1 (n=75) with chronic otitis media showed 90% hearing improvement after surgery (mean deficit 20 dB).
- Group 2 (n=70) with postero-superior TM reconstruction had 75% hearing improvement (mean deficit 30 dB), with better outcomes using prefascial lamina.
Impact:
- The study highlights the effectiveness of temporal muscle fascia grafts in tympanic membrane reconstruction.
- Prefascial lamina technique demonstrates superior hearing outcomes compared to traditional myringoplasty methods.
- This research contributes to optimizing surgical strategies for hearing restoration in otitis media patients.
