AbstractObjectivesTo determine the accuracy of antenatal ultrasound diagnosis of cleft lip with or without cleft palate (CL ± P) and isolated cleft palate (CP).MethodsThis was a retrospective review of 256 surviving cases referred in 2002–2003 for treatment of CL ± P.ResultsWe had referrals from 36 maternity units, 27 of which were in our local catchment area. There were 154 cases of CL ± P, of which five had microform CL. Of the remaining 149, 88 (59%) were diagnosed on antenatal ultrasound examination. Among these 88 cases there were minor reporting errors in 22 (25%). These errors were in describing the side and type of the lip cleft in 10 cases, predicting if there was a CP in 10 cases, and recognizing the anomaly in two cases. There were 102 cases referred with isolated CP, of which 92 had overt CP and 10 submucous CP. None of these was diagnosed by antenatal ultrasound imaging. There was no significant difference in the accuracy of ultrasound diagnosis between district hospitals and teaching/tertiary units.ConclusionsThere is a good awareness and ability to detect CL ± P by obstetric units from which referrals are received. Inaccuracies in antenatal ultrasound reports occur frequently when attempting to determine the type of CL and when predicting if there is a CP. We recommend that families should continue to be referred to specialist centers for counseling immediately after antenatal diagnosis, and comprehensive advice should always be given about clefts of the lip and palate.
