Abstract:
The objectives of the study are to evaluate the feasibility, results and complications of the endoscopic transcanal cartilaginous myringoplasty. Thirty patients with a tympanic membrane perforation underwent a transcanal endoscopic cartilaginous myringoplasty, between June 2008 and January 2010. Three patients had a residual perforation at 2 months after surgery. At 1 year, the perforation was closed for 29 patients (96 %). There was no case of blunting, lateralization of the tympanic membrane or ossicular injury. Two patients had an iatrogenic superficial cholesteatoma in the tympanic membrane. There was no significant postoperative worsening of sensorineural hearing loss. The preoperative Air Bone Gap (ABG) was not correlated with the size or site of TMP. The evolution of ABG postoperatively was not significant. The statistical analysis was performed by the Student's t test. The endoscopic transcanal cartilaginous myringoplasty is a minimally invasive, effective and reliable procedure in the management of the tympanic membrane perforations.
Insights
Endoscopic transcanal cartilaginous myringoplasty is a minimally invasive technique for tympanic membrane perforation repair. This study shows it is effective and reliable, with a 96% closure rate at one year.
Area of Science:
- Otolaryngology
- Minimally Invasive Surgery
- Surgical Outcomes
Background:
- Tympanic membrane perforations (TMP) can impair hearing and require surgical intervention.
- Traditional myringoplasty techniques have varying success rates and potential complications.
Purpose of the Study:
- To evaluate the feasibility, outcomes, and complications of endoscopic transcanal cartilaginous myringoplasty.
- To assess the efficacy of this minimally invasive approach for TMP closure.
Main Methods:
- Thirty patients with TMP underwent endoscopic transcanal cartilaginous myringoplasty.
- Surgical success, hearing outcomes (Air Bone Gap), and complications were assessed postoperatively.
- Statistical analysis included Student's t-test.
Main Results:
- A 96% perforation closure rate was achieved at one year (29/30 patients).
- No cases of tympanic membrane blunting, lateralization, or ossicular injury were reported.
- Two patients developed superficial iatrogenic cholesteatoma; no significant worsening of sensorineural hearing loss or Air Bone Gap occurred.
Conclusions:
- Endoscopic transcanal cartilaginous myringoplasty is a feasible, effective, and reliable procedure for managing tympanic membrane perforations.
- The technique offers a minimally invasive option with a high success rate and low complication profile.
