摘要

Background

Tragal cartilage is increasingly preferred for tympanic membrane reconstruction due to its durability. However, the optimal graft thickness remains controversial.

Objective

To compare hearing outcomes and graft uptake success in patients undergoing Type I cartilage tympanoplasty using varied thicknesses of tragal cartilage graft.

Methods

Sixty patients with chronic otitis media (COM), aged 12–50 years, underwent Type I cartilage tympanoplasty with tragal cartilage grafts divided into three groups: Group A (0.2–0.4 mm), Group B (0.5–0.7 mm), and Group C (0.8–1 mm). Pre- and postoperative hearing was assessed via pure tone audiometry (PTA) and air-bone gap (ABG). Graft uptake was evaluated in 1st & 6th week and 3rd month.

Results

Group A showed the greatest postoperative hearing improvement, with 35% achieving normal hearing and a mean PTA of 27.58 dB. Graft uptake was highest in Group C (90%), followed by Group A (85%) and Group B (85%). Differences in graft uptake were not statistically significant (p = 0.7395), but audiological improvements were significant across all groups (p < 0.001).

Conclusion

Partial-thickness tragal cartilage (0.2–0.4 mm) provides superior hearing outcomes without compromising graft uptake. Moderate-thickness cartilage (0.5–0.7 mm) offers a good balance between anatomical integrity and functional gain.
