The mucosal collar revisited.

Objectives: The mucosal collar was designed to achieve a cosmetically normal-appearing, circumcised phallus during hypospadias surgery. The original technique has been modified and refined since its introduction by Firlit in 1987. Herein, we provide a detailed description of the procedure as it is now performed.
Methods: From 1987 to 1998, more than 500 mucosal collars were created by the senior author as a routine component of the hypospadias repair.
Results: The mucosal collar produced a cosmetically normal-appearing, circumcised phallus in all cases. No associated morbidities attributable to the collar occurred.
Conclusions: The mucosal collar is a simple procedure to master and reproducibly yields a normal-appearing, circumcised phallus. The techniques used for urethroplasty are independent of the creation of the collar and will never preclude its use. We believe that the cosmetic outcome is unequaled by other techniques and that the collar should be used in all hypospadias surgery, regardless of the type of repair.
