Pterygium colli is a congenital deformity associated with malformation syndromes. Various surgical procedures have been reported, but these procedures have advantages and disadvantages. The modified posterolateral approach has been reported as a new surgical procedure for pterygium colli. However, there has been no confirmatory report. In this study, a case of pterygium colli that was treated with the modified posterolateral approach was reported. An 11-year-old girl with Turner syndrome was referred with chief complaints of web neck deformity and an abnormal hairline. The modified posterolateral approach was selected. Hairy excessive skin was excised at the posterolateral and posterior neck. An inferior skin incision was made parallel to the hairline, and a superior skin incision was made along the desired hairline. Hairless excessive skin was excised along the posterior midline of the neck. Undermining was extended over the sternocleidomastoid muscle, and flaps were rotated upward and inward. Z-plasty was performed at the posterior midline of the neck to prevent hypertrophic scar formation. The web neck deformity disappeared, but the patient expressed concern for excessive skin at the posterior midline. Thus, secondary surgery was performed 12 months later. The operative scar was opened 2 months after secondary surgery owing to suture abscess, and the wound was closed directly. The web neck deformity had not recurred, and the natural hairline was maintained at 65 months after the primary surgery. The modified posterolateral approach is beneficial for pterygium colli, because it allows the correction of the web neck deformity and abnormal hairline without a noticeable scar.
