Endoscopic tympanoplasty with limited tympanomeatal flap elevation in pediatric cases: comparison of anatomic and audiological results of grafts

The anatomical and functional success rates of tragal cartilage perichondrium and temporal muscle fascia, in pediatric patients who underwent endoscopic type 1 tympanoplasty with limited tympanomeatal flap elevation, were compared.
In total, 35 pediatric patients (21 females, 14 males; mean age 11.0 ± 1.5 years; range 8–14 years) who underwent transcanal endoscopic type 1 tympanoplasty with limited elevation of the tympanomeatal flap were included in this study. Patients in group A received a tragal cartilage perichondrium graft and those in group B received a temporal muscle fascia graft. The groups were compared with respect to the pre- and postoperative air–bone gap (ABG) and tympanic membrane status.
The mean preoperative and postoperative ABG were 27.0 ± 9.2 and 9.0 ± 8.5 dB in group A, and 26.8 ± 8.8 and 11.6 ± 9.2 dB in group B, respectively. The group differences in pre- and postoperative ABG values were not significant (p = 0.882 and p = 0.417, respectively). However, in both groups, the postoperative ABG was significantly lower than the preoperative ABG (both p = 0.0001). The graft retention rate was 100% in group A and 88.2% in group B; the difference was not statistically significant (p = 0.134). There was also no statistically significant difference between the pre- and postoperative bone conduction values of the patients at 0.5, 1, 2, 3 or 4 kHz (all p > 0.05).
Our study demonstrated that in pediatric patients undergoing endoscopic tympanoplasty, both the tragal cartilage perichondrium and the temporal muscle fascia can be used successfully and safely as grafts in endoscopic type 1 tympanoplasty performed by limited tympanomeatal flap elevation.
