Autologous ossicle and cortical bone in ossicular reconstruction

Area of Science:

• Otolaryngology
• Surgical Innovation
• Biomaterials in Medicine

Background:

• Chronic ear disease affects numerous patients, often requiring surgical intervention.
• Cholesteatoma is a common indication for tympanoplasty, necessitating ossicular reconstruction.
• Previous methods involved artificial prostheses, sometimes leading to complications.

Purpose of the Study:

• To evaluate the efficacy of autologous ossicle or cortical bone in tympanoplasty.
• To compare outcomes between autologous grafts and artificial prostheses.
• To identify factors influencing surgical success in chronic ear cases.

Main Methods:

• A retrospective study of 315 tympanoplasty cases in chronic ears.
• Analysis of surgeries performed for cholesteatoma (62% of cases).
• Mean follow-up duration of 5.4 years, assessing graft success and complications.

Main Results:

• Successful outcomes were achieved using autologous ossicle or cortical bone grafts.
• The presence of the stapes significantly correlated with better surgical results.
• No foreign body reactions were observed with autologous materials.

Conclusions:

• Autologous ossicle or cortical bone is a safe and effective material for ossicular reconstruction.
• This technique offers advantages over artificial prostheses by preventing foreign body reactions.
• Preservation of the stapes is a key factor for optimal tympanoplasty outcomes in chronic ear disease.
