Homograft sclera in tympanoplasty

Area of Science:

• Otolaryngology
• Ophthalmology
• Biomaterials Science

Background:

• Tympanoplasty often faces challenges with tympanic membrane support and fascia reinforcement.
• Existing techniques may lead to complications like lateral healing and anterior blunting.

Purpose of the Study:

• To evaluate the efficacy of homograft sclera as a scaffold and reinforcement in tympanoplasty.
• To assess the complication rates and graft success using sclera in tympanic membrane reconstruction.

Main Methods:

• Homograft sclera, preserved in 70% alcohol, was utilized as a supporting scaffold.
• A specific interdigitated grafting technique was employed, with fascia placed lateral to the sclera.
• Surgical outcomes were observed in 43 patients, with follow-up periods exceeding 3-6 months for most.

Main Results:

• A high postoperative tympanic membrane closure rate of 90% was achieved across various tympanoplasty types (excluding Type IV).
• No recognizable complications were observed during the follow-up period.
• The technique appears promising in mitigating complications associated with traditional fascia grafting.

Conclusions:

• Homograft sclera is a viable and safe option for tympanic membrane reconstruction and fascia reinforcement.
• This method demonstrates potential for reducing common surgical complications in tympanoplasty.
• Further long-term studies are warranted to fully assess the durability and benefits of scleral grafting.
