Lateral cervical advancement flaps for the correction of webbed-neck deformity.

In the webbed-neck deformity, a horizontal excess of cervical skin creates bilateral and often asymmetrical skin webs from the mastoid to the acromion. Hair extends laterally to the free edge on the posterior web surface, creating a wide nuchal hairline. A technique of correction is presented. Through an incision along or within the hairline, the glabrous anterior web surface is undermined with the platysma muscle into the anterior cervical triangle until posterosuperior traction will obliterate the web. The posterior hair-bearing web surface is also elevated, and an excess of scalp is excised anterior to the new hairline position determined by the surgeon. The anterior glabrous flap is advanced posteriorly to resurface the scalp defect and recreate a normal neck contour and symmetrical hairline. A Szymanowski triangle of scalp is excised to equalize wound margins creating two "lazy" Y incisions that join in the scalp midline on completion of the opposite neck web. All scars lie within or along the hairline or extend onto the posterolateral shoulder. The method allows precise control of bilateral neck contour and hairline position without intraoperative repositioning and avoids scars on the exposed anterolateral cervical surface. There has been no recurrence of the neck deformity after 2 years.
