Cleft palate without cleft lip Description: A congenital anomaly characterised by a closure defect of the hard and/or soft palate behind the foramen incisivum without a cleft lip. This anomaly includes sub-mucous cleft palate, but excludes cleft palate with a cleft lip, a functional short palate and high narrow palate. ICD-9-BPA codes: 749.00–749.09 ICD-10-AM codes: Q35.0–Q35.9 Cleft palate without cleft lip was reported in 8.1 per 10,000 births. This overall rate has increased to 9.1 when the rate was estimated using data from the four states that include TOP data. The reported number of fetal deaths or early terminations of pregnancy with this anomaly was small and these deaths or terminations could be due to other associated anomalies. However there was an increase in the number of notified pregnancies with cleft palate without cleft lip in 2003 (Figure 15). The data from four states providing information on TOP show that the estimated rate increased from 7.7 per 10,000 pregnancies in 2002 to 10.4 per 10,000 pregnancies in 2003 (Table 2.15.2). The proportion of females with this anomaly was higher (56.9%) than males. This anomaly was seen in 52.7 per 10,000 babies born before 25 weeks of gestation. Of the babies who had this anomaly 83.0% were born at term and most of the babies (82.7%) had a birthweight of 2,500 grams or more (Table 2.15.3). Women aged 40 years or older and women born in South Central America or the Caribbean region had the highest rates of affected births. Multiple births had a significantly higher rate of affected babies than singleton births (PR=1.9, CI 1.1–3.3). The rates did not differ significantly by Indigenous status or areas of residence (Table 2.15.6).
