Background: The webbed neck is a very distinct and easily recognizable   deformity due to the widened triangular base of the neck. The cause of the splayed neck appearance is due to a combination of excessive lateral and vertically short skin, a widened trapezius muscle and low set ears. The typical low hairline displacement that is seen is a sequelae of this neck anatomy aberrations not the cause of them.

Improving the neck webs has a long surgical history which has been understandably focused on directly treating the webs. Through excision and a tissue rearrangement strategy (e.g., z-plasties) the laterally displaced longitudinal bands are transposed medially. While an effective surgical technique the tradeoff of the scars gives pause as the scars present their own aesthetic liability. Many patients would not consider the scars as an aesthetic improvement.

As a result an alternative approach is to change the location of the excision and tissue rearrangement to a less visible location away from the side of the neck. This is an unconventional approach in that where the surgery is performed is not where the result is trying to be achieved. Meaning the webs are going to be relocated by unraveling them and moving the lateral tissues (skin and muscle) into the defect created on the back of the neck.       

Case Study: This female had large congenital neck webs that had some muscle to them but were largely skin folds. The neck was vertically short and the hairline was very low and out onto the neck webs. By palpation (pinch test) the posterior neck tissues had good mobility. 

Under general anesthesia and in the prone position a diamond excision pattern was marked on the back using a horizontally marked line at the point between the two webs where maximal inward movement was desired. The posterior neck skin and a very thick layer of fat underneath it was removed exposing the muscle fascia.

The skin flaps were then raised off of the fascia out to the lateral extent of the skin webs. Midline fascial plication was done pulling the neck webs closer. The outer edge of the trapezius muscle was identified and a strip of muscle was elevated from its superior location below the ears down to the outermost webbing. With their bases intact the strips of muscle were oriented horizontally across each other and seen together…further pulling in the webs. This allowed the skin edges to move more medially for a midline closure.

In closing the thick skin flaps down the midline it was necessary to extend the excision inferiorly to work out bunched up tissues forming  below the closure line. Even then it was not possible to work out all the bunching but much of this will even itself out as its heals.

When seen the next day the change in the neck webbing could be appreciated. To no surprise this will definitely cause some neck stiffness for awhile after the procedure.

By laying over the excised neck tissues on the midline closure it is now easier to understand the posterior approach to the webbed neck….lateral neck web translocation into the open excised area at the back of the neck. This puts the scar line in a hidden location particularly in females with their hair density. This procedure may be less advantageous in a male with very short hair even though the scar is not on both sides of the neck.

While the posterior approach is conceptually appealing the true final result will not be fully appreciated until 6 to 8 weeks after the surgery. At the end of surgery this is the ideal or most neck webbing correction that will be achieved. But there is always going to some amount of relapse as to how much medialization of the webs persist given that the webs are relocated not excised (cut out) It is impossible to predict exactly how much the relapse will be but it is never 0% nor is it 100% either. I would say it is more in the 20% to 30% range in most patients.

Key Points:

1) The webbed neck has a variety of presentations that can affect a webbed neck correction. 

2) The posterior approach to webbed neck correction involves central tissue excision and skin web and trapezius muscle translocation. 

3) Some relapse of webbed neck correction through tissue translocation does occur and is maximized bye 6 weeks after the surgery.
