Endoscopic myringoplasty in pediatric patients: a comparison of cartilage graft push-through and underlay fascia graft techniques.

BACKGROUND

Although myringoplasty is performed in pediatric patients, there is still no consensus on the graft material and surgerical procedure.

OBJECTIVE

To compare the short-and long- term graft take rates of the cartilage push-through and fascia graft techniques employed during pediatric myringoplasty.

MATERIALS AND METHODS

93 pediatric patients with perforation who underwent myringoplasty were randomized into the cartilage push-through and underlay fascia graft group. The outcomes evaluated were hearing gains, and graft success rates at 12 and 24 months.

RESULTS

The graft success rate was similar between two groups (95.7% vs 91.3%,  = .653) at postoperative 12th months, however, the graft success rate was significantly higher 91.5% for the cartilage graft group compared with 73.9% for the fascia group at postoperative 24th months. No significant between-group differences were observed pre- ( = .694) or post- ( = .812) operative ABG values or mean ABG gain ( = .745).The re-perforation rate in fascia group was significantly higher than that in push through group (19.05 vs. 4.44%). No middle ear cholesteatoma formation was found in either group.

CONCLUSION

Endoscopic cartilage push-through and underlay fascia graft myringoplasty afforded comparable hearing results in pediatric patients; however, the push-through technique without the elevation of a tympanomeatal flap exhibited better long-term graft success rate compared to underlay fascia graft.
