Surgical correction of Tessier cleft no. 7: A single center 18-year experience.

Abstract

Tessier cleft 7 are rare craniofacial clefts. Live-birth incidence varies from 1/80,000 to 1/300,000, with the incidence of 1 in 120 craniofacial clefts among Asians. Its clinical presentation varies widely in severity, thus, complicating diagnosis and contributing to the lack of consensus regarding its surgical management. The aim of this study is to describe clinical findings, types of Tessier cleft 7 soft tissue repair, and its outcomes in Kuala Lumpur Hospital. This retrospective study reviewed records of children operated from January 2001 to July 2019. Data regarding concurrent congenital anomalies, complications, type of surgery, etc., were collected from outpatient records, operative notes, and clinical photographs. Twenty-eight children were treated, and 33 clefts (5 bilateral) were repaired. The male-to-female ratio was 1.3:1 (16 males and 12 females). Twenty-three patients had unilateral clefts (82.14%), with 14 right (60.86%) and 8 left (34.78%). Bilateral clefts were less common (17.86%). Twenty-three patients (82.14%) were Malay, 3 (10.71%) Chinese, 1 (3.57%) Indian, and 1 (3.57%) Cambodian. Eleven medical records were untraceable (discontinued due to duration of inactivity). There were 10 straight-line repairs, 5 Z-plasties, and 1 W-plasty performed; 3 cases did not detail the type of repair. One child required scar revision, and 1 had hypertrophic scarring requiring corticosteroid injection-no disturbances in speech or oral incompetency while eating were reported. Duration of follow-up ranged from 3 to 14 years. Our center has a higher rate of Tessier cleft 7 attendance. Straight-line cutaneous repairs combined with inferior vermilion mucosal flap can be used with low rates of complication and revision surgery.
