Type 1 tympanoplasty in pediatric patients: Comparison of fascia and perichondrium grafts

Objective: The timing of tympanoplasty in the pediatric age group is an ongoing debate. The purpose of this study was to analyze and compare the success of grafts in type 1 tympanoplasty in pediatric patients, and to evaluate the prognostic factors that may affect its success. Materials and methods: A retrospective study of 42 pediatric patients who were younger than 18 years and underwent a primary type 1 tympanoplasty using tragal cartilage perichondrium and temporalis fascia from January 2013 to December 2018, were evaluated. A total of 42 medical records of children aged between 8 and 18 years (20 female, 22 male) were reviewed. Age, gender, co-morbidities, perforation size and location, type (central, marginal), pre- and post-operative hearing levels, mean air-bone gap (ABG), graft material (fascia, perichondrium), length of follow up and surgical outcomes were collected. Results: The overall graft success rate was 83.3% (out of 35 patients). The graft success rate was significantly higher 95.2% (20/21) for the perichondrium group compared with 71.4% (15/21) for the temporal fascia group (p = 0.023). The functional success rate (postoperative air-bone gap < 20 dB) obtained in the perichondrium group was 90.4% (19/21) and 85.7% (18/21) in the fascia group, respectively. After a mean follow-up of 27.5 +/- 11.55 months, the mean hearing improvement was 11.26 +/- 7.53 dBHL for overall the group. Presence of contralateral otitis media with effusion (OME) was found a risk for reperforation and bilateral perforations were negatively affected graft success rate (p < 0.01). Graft success did not affected by age, gender and type and location of perforation (p > 0.05). Conclusion: Both temporalis fascia and tragal cartilage perichondrium are suitable graft materials for pediatric tympanoplasty with 83.3% of graft success rate. Tragal cartilage perichondrium may be the first choice of graft material due to its high success rates. There were no significant differences between the fascia and perichondrium groups in terms of functional results. Reperforation is more likely to occur in bilateral perforations and contralateral OME, and should be treated with perichondrium or cartilage graft.
