Abstract

Objectives

To evaluate and compare functional outcomes of tympanoplasty procedures with temporalis fascia and four different types of cartilage grafts in chronic otitis media (COM) cases with normal preoperative hearing levels.

Methods

Records of patients who underwent type 1 tympanoplasty for non-complicated COM in a tertiary medical center between January 2010 and January 2017 were reviewed. Patients with central or marginal and dry perforations of the tympanic membrane, normal middle ear mucosa, intact ossicular chain and patients with a preoperative pure tone average (PTA) level of 25 dB or less and a word recognition score (WRS) of 88% or greater were included in the study. Graft success rates, preoperative and postoperative functional outcomes, and anatomical results were analyzed.

Results

One hundred and forty-four patients who met the inclusion criteria were evaluated in the study. PTA and Air-bone gap (ABG) levels decreased significantly both in TF and CG groups after the surgery (p = 0.001). Similarly, WRS scores increased significantly in both groups (p = 0.001). There was not a significant difference in terms of PTA increase, WRS increase, and ABG closure levels between cartilage and TF groups. Increase in PTA, closure in ABG, and increase in WRS levels were compared among TF, WsCCG, MCG, PCG, and CPIG groups. The increase in PTA levels was also found to be significantly superior in the TF group (p = 0,023). However, the multivariate analysis showed no significant difference for increase in WRS, closure in ABG and increase in PTA levels according to graft type (p = 0.285; p = 0.461; p = 0.106, respectively) and gender (p = 0.487; p = 0.811; p = 0.756, respectively).

Conclusion

In COM cases with normal preoperative hearing, both TF and cartilage lead to superb functional and anatomical outcomes. There was not a significant difference in terms of PTA increase, WRS increase and ABG closure levels between cartilage and TF groups. The graft success rate of cartilage was found to be superior to TF, but there was not a statistically significant difference. Different types of cartilage grafts can be used in cases with normal preoperative hearing without the concern of hearing impairment.
