Noonan syndrome and correction of the webbed neck.

Abstract

We report on a 16-year-old boy with Noonan syndrome who had short stature, hypertelorism, mild hearing loss, webbed neck, pectus deformities, hypertrophic cardiomyopathy, low posterior hairline, redundant skin, café au lait spot, curled hairs, foetal pads, and undescended testes. The father and a sister of the boy were also found with mild webbed neck, being possibly mildly affected individuals. The significant webbed-neck deformity of the boy was completely corrected by subcutaneous resection of the proximal half of the hypertrophic fascia bands, through small incisions hidden within the hairline. The advantage of this procedure is simple, safe and effective, with no visible scar on the surface of the neck.
