Mucosal reduction for correction of congenital maxillary double lip.

摘要

Congenital double lip is rare and usually involves the upper lip. A part from a deformity that interferes with speech and mastication, operation may be indicated for cosmetic reasons. We report a case of 12 years old patient with double lip deformities who was operated in our department for cosmetic reasons. We used an elliptical excision of the mucosal excess. Satisfactory aesthetic results were achieved. Introduction Congenital double lip is rare and generally involves the upper lip (1). A double vermilion with a transverse furrow between the two borders appears when the orbicularis oris musclecontracts during a smile. The incidence of this anomaly is not known and it may be either isolated or in association with other congenital abnormalities. (2) Treatment is by excision of the excess mucosa and submucosal tissue. We present a case of congenital double lip with literature review. Case report A 13-year-old boy was evaluated for excess maxillary labial mucosa with the resulting appearance of a maxillary double lip (Fig. 1). The deformities had been present since birth and became more prominent as he grew. No other congenital deformities were noted.The appearance of the lip was due to folding of the mucosa as the lip was retracted when smiling (Fig. 2). The excess labial mucosa was localized to either side of the midline (Fig. 3), forming a sessile, hypertrophied mass that extended mediolaterally the distance between the midpoints of the maxillary lateral incisors.We operated under general anaesthesia. The excess buccal mucosa was excised by two elliptical excisions, one on each half of the lip, and combined with a central Z-plasty to release the constricting band (Fig. 4). Closure was by running 4/0 polyglactin 910 (Vycril) suture (Fig. 5). Postoperative recovery was uneventful apart from swelling that resolved in about 10 days.He was happy with the cosmetic results. After two years there were no signs of relapse or late complications.
