Prognostic factors in type I tympanoplasty

Area of Science:

• Otolaryngology
• Surgical Outcomes
• Middle Ear Surgery

Background:

• Type I tympanoplasty aims to restore the tympanic membrane and hearing.
• Identifying preoperative factors influencing success is crucial for patient selection and surgical planning.

Purpose of the Study:

• To identify preoperative factors affecting type I tympanoplasty success.
• To compare the efficacy of different graft materials based on these factors.

Main Methods:

• Analysis of 247 type I tympanoplasty procedures.
• Evaluation of preoperative variables: age, prior surgery, contralateral ear status, perforation size, septal/adenoid pathology, smoking.
• Stratification by graft material: temporalis fascia (TF) vs. perichondrium-cartilage island flap (PCIF).

Main Results:

• PCIF grafts had higher graft take rates (87.8%) than TF grafts (72.3%).
• TF graft success was lower in young patients, those with adenoid hypertrophy, or contralateral ear disease.
• PCIF graft success was not significantly affected by tested preoperative variables.
• Hearing improvement was comparable between TF and PCIF grafts.

Conclusions:

• Tympanoplasty with cartilage grafts offers superior graft take compared to TF grafts.
• Cartilage grafts are recommended for patients with risk factors like young age, adenoid disease, or contralateral ear issues.
• Hearing outcomes are similar regardless of graft type, but graft success is enhanced with cartilage.
