Surgical correction of whistle deformity

Whistle deformity is one of the most common deformities of the upper lip in bilateral cleft lip patients. Surgical correction is needed when patient cannot seal their lips during resting position. Bilateral lateral vermilion border transposition flap was developed for correction of midline tissue defect in cleft patient. Double pendulum flaps could be transposed to the central area to augment midline tissue defect. In this case report, a 30-year-old bilateral cleft patient presented to correct whistle lip deformity. A modified bilateral lateral vermilion border transposition flap was performed successfully without disrupting orbicularis oris muscle. This method is reliable for correction of whistle lip deformity with ample mucosa in the lateral sides of the upper lip.
