Predictive Factors and Audiometric Outcome Comparison Between Titanium Prosthesis and Autologous Incus in Traumatic...

Area of Science:

• Otolaryngology
• Trauma Surgery
• Audiology

Background:

• Traumatic ossicular injury can lead to significant hearing loss.
• Ossiculoplasty is a surgical procedure to reconstruct the middle ear ossicles.

Purpose of the Study:

• To investigate the etiology and pathology of traumatic ossicular injury in Taiwan.
• To compare hearing outcomes and predictive factors of ossiculoplasty using titanium prosthesis versus autologous incus.

Main Methods:

• Retrospective analysis of patients with traumatic ossicular injury from 2011-2020 in Taiwan.
• Patients were categorized into titanium or autologous material groups for ossiculoplasty.
• Audiometric outcomes and predictive factors were analyzed.

Main Results:

• Significant improvements in hearing threshold and air-bone gap were observed post-surgery.
• No significant difference in hearing improvement between titanium and autologous groups.
• Vertigo, benign paroxysmal positional vertigo, and temporal bone fracture were identified as negative predictive factors for hearing gain.

Conclusions:

• Ossiculoplasty with titanium or autologous materials yields favorable hearing recovery in traumatic ossicular injury.
• Certain conditions like vertigo and temporal bone fractures negatively influence surgical hearing benefit.
