Summary
Ossiculoplasty using various graft materials achieved an 80% success rate in reconstructing the ossicular chain for chronic otitis media. Specific graft choices like autograft incus and partial ossicular replacement prosthesis (PORP) showed better outcomes with the malleus handle present.
Area of Science:
- Otolaryngology
- Surgical Innovation
- Hearing Reconstruction
Background:
- Ossicular graft materials enhance hearing outcomes in tympanoplasty and tympanomastoid surgery for chronic otitis media.
- Choosing the optimal middle ear implant for ossicular chain reconstruction can be challenging for otologists.
Purpose of the Study:
- To evaluate the effectiveness of different ossicular graft materials in ossiculoplasty.
- To determine factors influencing successful hearing reconstruction in chronic otitis media.
Main Methods:
- A prospective study of 80 patients with chronic suppurative otitis media and significant air-bone gap (>25 dB) was conducted.
- Total ossicular replacement prosthesis (TORP), partial ossicular replacement prosthesis (PORP), and refashioned incus were utilized.
- Success was defined as achieving an air-bone gap <25 dB 90 days post-surgery.
Main Results:
- The study included middle-aged patients with moderate conductive hearing loss.
- An overall success rate of 80.0% was achieved, with an average air-bone gap improvement of 15.76 dB.
- The incus was identified as the most frequently affected ossicle.
Conclusions:
- Ossiculoplasty results are improving with advancements in understanding middle ear mechanics.
- Preoperative ear discharge severity, mastoid cellularity, disease presence, and surgical technique are significant prognostic factors.
- Autograft incus and PORP performed better with an intact malleus handle, while TORP was more effective when the malleus handle was eroded.
