Does concurrent adenoidectomy or tonsillectomy affect the graft success rate of cartilage myringoplasty in adults?

BACKGROUND

The objective of this study was to evaluate the graft success and hearing outcomes of concurrent adenoidectomy or tonsillectomy and myringoplasty.

METHODS

Medical case notes were reviewed for all adult patients with dry perforations who had undergone myringoplasty, with or without concurrent throat surgery, from December 2015 to February 2018. The study population was divided into concurrent myringoplasty and throat surgery (Group A) and single myringoplasty (Group B) groups. The air-bone gap (ABG) and graft success rate were evaluated in both groups.

RESULTS

A total of 131 ears of 131 patients were included in this study. In total, 33 ears of 33 patients were assigned to Group A and 98 to Group B. Of the 33 patients in Group A, adenoid residue was detected in 3, chronic tonsillitis in 21, and tonsil hypertrophy in 9. The graft success rate was 96.9 % in Group A and 96.9 % in Group B at 6 months postoperatively (p = 0.993). In addition, the graft success rate was 87.9 % in Group A and 92.8 % in Group B at 24 months postoperatively (p = 0.372). Reperforation occurred in three patients in Group A and four in Group B; the difference was not significant. No significant group differences were observed in preoperative (p = 0.654) or postoperative (p = 0.791) ABG values or mean ABG gain (p = 0.439). No patient in either group developed cholesteatoma of the middle ear.

CONCLUSIONS

Simultaneous adenoidectomy or tonsillectomy and myringoplasty is feasible but does not improve the graft success rate or hearing outcome.
