|Australian Palate Abnormalities (2002-2003)
|Cleft lip with or without cleft palate (9.2 per 10,000 births) ICD-10 Q36.0, Q36.1, Q36.9, Q37.0–Q37.5, Q37.8, Q37.9
|A congenital anomaly characterised by a partial or complete clefting of the upper lip, with or without clefting of the alveolar ridge or the hard palate. Excludes a midline cleft of the upper or lower lip and an oblique facial fissure (going towards the eye).
- 17% of the affected pregnancies were terminated in early pregnancy or resulted in fetal deaths. Most of the fetal deaths or terminations of pregnancy (95%) had multiple abnormalities.
- more commonly seen in males than in females.
- babies born before 25 weeks of gestation, 150 per 10,000 births had this anomaly. Most babies (80.0%) were born at term with a birthweight of 2,500 grams or more.
- Maternal age group was not associated with the anomaly.
- Rates significantly higher among Indigenous women than non Indigenous women.
|Cleft palate without cleft lip (8.1 per 10,000 births) ICD-10 Q35.0–Q35.9
|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.
- 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.
- proportion of females with this anomaly was higher (56.9%) than males.
- 52.7 per 10,000 babies born before 25 weeks of gestation.
- 83.0% were born at term and most of the babies (82.7%) had a birthweight of 2,500 grams or more.
- 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.
- Rates did not differ significantly by Indigenous status or areas of residence.
