Myringoplasty Using Human Birth Tissue Allografts to Repair Large Tympanic Membrane Perforations

Objective: Examine outcomes among a series of pediatric patients who underwent myringoplasty using human birth tissue (BT) for repair of large tympanic membrane (TM) perforations.

Study design: Case series.

Setting: Single-institution pediatric hospital.

Methods: Retrospective chart review of patients treated with BT during a 4-year study period. Subjects who underwent myringoplasty for large (size 40% or greater) TM perforations were included for this study. Patients with a stable perforation of at least 1 month's duration preoperatively who then followed up for at least 3 months postoperatively met inclusion criteria.

Results: Six subjects were included in this study. One subject underwent bilateral repair; thus, this series includes a total of 7 perforations. TM perforations ranged from 40% to 70% of the TM. At initial follow-up (median of 2 months), 5 of the 7 perforations had healed. One of these 5 had evidence of a 10% recurrent perforation at 5 months, which subsequently healed. Of the 2 patients not healed at initial follow-up, 1 had only a residual pinpoint perforation that subsequently healed; the other had a persistent 30% perforation that was possibly related to their postoperative recovery period, which was complicated by a respiratory viral illness.

Conclusion: For large TM perforations, myringoplasty with BT grafts may be a viable alternative to longer, more invasive procedures like tympanoplasty. Larger, randomized, prospective studies are needed.
