A webbed neck, or pterygium colli deformity, is a congenital skin fold that runs along the sides of the neck down to the shoulders. There are many variants.

Associated conditions

It is a feature of Turner syndrome^[1] (only found in girls) and Noonan syndrome,^[2] as well as the rarer Klippel-Feil syndrome.^[3]

Presentation

On babies, webbed neck may look like loose folds of skin on the neck. As the child grows, the skin may stretch out to look like there is little or no neck.

M to T rearrangement: an approach to correct webbed neck deformity.

Murthy AS1, McGraw M2.Author information 1Division of Plastic Surgery, Akron Children's Hospital, One Perkins Square, Akron, OH 44308, USA.2The University of Toledo College of Medicine, Toledo, OH 43606, USA.AbstractFor the Noonan syndrome patient, the most concerning physical defect is often congenital webbing of the neck or pterygium colli. We present a patient with pterygium colli and a low and laterally displaced nuchal hairline. Since its description, various surgical approaches have been implemented to correct the deformity. Previously reported posterior and lateral approaches have notable disadvantages with regard to hairline displacement and recurrence. In order to address these disadvantages, a new surgical technique was used on this patient. We have termed this technique an M to T rearrangement. Using a lateral approach, the M and T incisions are made and the trapezial fascial web is directly visualized and able to be completely excised. This prevents the recurrence seen with the use of posterior techniques. Inferolateral displacement of hair-bearing skin can be removed with resection of the superior intervening triangle and improves the appearance of the low nuchal hairline. The excision of excess skin along with the zig-zag closure also prevents postoperative scar contraction and recurrence. An important effect of this technique is the prevention of anterior displacement of hair bearing skin. M to T rearrangement is an effective technique for the correction of webbed neck deformities seen in Noonan and Turner syndromes.

Posso CM1, Wolff GA, Suarez LD.Author information 1Service de chirurgie plastique maxillofaciale et de la main, département de chirurgie, hôpital San Vicente de Paul, faculté de médecine, Universidad de Antioquia, Medellín, Colombia. carolina.posso@gmail.comAbstractCongenital web neck is a deformity hardly ever reported in the English literature. It is usually associated to Ulrrich-Turner syndrome. There are several options to correct this deformity, but in severe cases complete correction of the web and the abnormal back hair is not always possible. We present our experience with a secondary case where previous butterfly method was employed, a combined procedure was used achieving a satisfactory result. We considered that this technique is useful and offers an important improvement of the contour.
