title: Transverse facial cleft: A series of 17 cases.
abstract: BACKGROUND
  Transverse facial cleft (Tessier type 7) or congenital macrostomia is a rare congenital anomaly seldom occurring alone and is frequently associated with deformities of the structures developing from the first and second branchial arches. The reported incidence of No. 7 cleft varies from 1 in 60,000 to 1 in 300,000 live births.
  
  
  METHODS
  Seventeen patients of transeverse facial cleft who presented to us in last 5 years were included in the study. Their history regarding familial and environmental predispositions was recorded. The cases were analysed on basis of sex, laterality, severity, associated anomalies and were graded according to severity. They were operated by z plasty technique and were followed up for 2 years to look for effectiveness of the technique and its complications.
  
  
  RESULTS
  Out of the seventeen patients of transverse cleft, none had familial predilection or any environmental etiology like antenatal radiological exposure or intake of drugs of teratogenic potential. Most of the patients (9/17) were associated with hemifacial microsomia and 1 patient was associated with Treacher Colin's Syndrome. Out of the 6 cases of Grade I clefts, 4 were isolated transverse clefts and of the 10 patients of Grade II clefts, 7 were associated with hemifacial microsomia. We encountered only one case of Grade III Transverse Cleft which was not only associated with hemifacial microsomia but also had cardiac anomaly. Out of the 17 cases, 15 were operated and in most of them the outcome was satisfactory.
