A comparison of commissure excursion following gracilis muscle transplantation for facial paralysis using a cross-face nerve graft versus the motor nerve to the masseter nerve.

摘要: Background: The microneurovascular transfer of a free muscle transplant is the procedure choice for facial animation in child with paralysis. One critical factors this selection motor nerve to innervate transplanted muscle. Methods: From 1989 1999, 166 segmental gracilis transfers were performed 121 children animation. cross-face graft was used 70 procedures (cross-face group) by branches seventh normal side. ipsilateral masseteric 94 (50 patients, masseter and accessory two (one patient). To compare operative between first groups, all charts reviewed. extent oral commissure movement determined measurements taken from tragion commissure, both at rest full smile. In group (n = 20), extents measured on side reconstructed side; 16), they left right sides. Results: No significant difference found groups (p < 0.05) mean age time transplantation, total operation length or fraction circumference segment used. Although variables similar excursion differed. Excursion less than that 0.0006) 0.0000) group. Itwas also Also, there no sides within 0.05). Furthermore, 0.35, p 0.61). Conclusion: These results indicate transplantation using very reproducible provides range normal.
