Fetal Alcohol Syndrome (FAS) is a permanent condition that occurs when a woman consumes alcohol during pregnancy. It is the most severe condition within a group of conditions called fetal alcohol spectrum disorders (FASDs). FASDs can cause a wide range of physical, behavioural, cognitive, and functional issues, with the most severe cases resulting in FAS. The facial characteristics of FAS include abnormal facial features, such as a smooth ridge between the nose and upper lip, a thin upper lip, small eyes, and small eye openings. These facial characteristics can be used to diagnose FAS, even in the absence of confirmation of prenatal alcohol exposure.

Small eye openings
Fetal Alcohol Syndrome (FAS) is a permanent condition that occurs when a woman consumes any amount of alcohol during her pregnancy. Alcohol consumption during pregnancy can interfere with the baby's development, causing physical and mental defects.
In addition to small eye openings, FAS can cause a range of other eye abnormalities, including:
- Widely spaced eyes (telecanthus) due to short palpebral fissures.
- Prominent epicanthal folds, which are larger-than-normal skin folds near the inner corner of the eyes.
- Ptosis or drooping eyelids.
- Optic nerve hypoplasia, which is underdevelopment of the optic nerve.
- Increased tortuosity of the retinal vessels, resulting in disturbed retinal function.
The detrimental effects of alcohol on the fetal eye are less recognised compared to other manifestations of FAS. However, they are significant in terms of both diagnosis and management. While the relationship between alcohol and teratogenesis is well-established, the threshold for safe alcohol consumption during pregnancy remains unclear.
FAS is a severe condition within the group of disorders known as Fetal Alcohol Spectrum Disorders (FASDs). These disorders can affect a child's movement, learning, emotional development, and communication skills. Early diagnosis and appropriate support are crucial for managing FAS and FASDs.

Thin upper lip
Fetal Alcohol Syndrome (FAS) is a permanent condition that occurs when a woman consumes any amount of alcohol during her pregnancy. Alcohol consumption during pregnancy can interfere with the baby's development, causing physical and mental defects.
FAS is the most severe condition within a group of conditions called fetal alcohol spectrum disorders (FASDs). FASDs are caused by the effects of maternal alcohol consumption during pregnancy and can result in physical birth defects that affect the heart, eyes, skeletal system, ears, and kidneys.
One of the characteristic facial features of FAS is a thin upper lip. This is often accompanied by a smooth connection between the nose and the upper lip, known as a smooth philtrum, and small eyes. The thin upper lip in individuals with FAS may indicate the degree of brain damage, as studies have shown that prenatal alcohol exposure can lead to both brain and craniofacial abnormalities.
The Centers for Disease Control and Prevention's diagnostic criteria for FAS include the presence of a thin vermilion border of the upper lip, along with a smooth philtrum and short palpebral fissures. The vermilion border is the edge of the lip where it meets the skin of the face, and in individuals with FAS, the Cupid's bow shape of this border may be lost or underdeveloped, resulting in a thinner appearance of the upper lip.
It is important to note that FAS can be difficult to diagnose, and there is no direct test for it. Pediatric providers often rely on the presence of specific physical signs and symptoms, such as the thin upper lip, along with the child's size and history of alcohol exposure during pregnancy, to make a diagnosis.

Flat nose bridge
Fetal Alcohol Syndrome (FAS) is a group of neurological, behavioural, and physical birth defects that arise when a pregnant woman consumes alcohol. It is a permanent and severe condition within the spectrum of fetal alcohol spectrum disorders (FASDs). The severity of FAS depends on the amount of alcohol consumed and the timing of exposure during the pregnancy.
FAS affects the facial features of those affected, including the nose. A flat nose bridge is one of the characteristic facial abnormalities associated with FAS. This feature is often accompanied by other distinctive traits, such as small eye openings, a thin upper lip, and a smooth connection between the nose and upper lip. These facial abnormalities can be subtle and may become less noticeable as the child ages. However, the emotional and behavioural problems associated with FAS may increase over time.
The diagnosis of FAS can be challenging due to the absence of a direct test. Pediatric providers rely on physical signs, symptoms that develop over time, and a history of alcohol consumption by the mother during pregnancy. Early diagnosis is crucial to facilitate intervention programs, such as speech therapy, physical therapy, and special assistance in school.
While there is no cure for FAS, surgical interventions can correct major physical defects. Treatment plans typically involve a combination of medication and behavioural therapy to help individuals manage their symptoms. Additionally, counselling and support groups can assist mothers struggling with alcohol abuse and coping with the challenges of raising a child with FAS.
It is important to note that FAS is entirely preventable by abstaining from alcohol consumption during pregnancy. If alcohol has been consumed during pregnancy, it is crucial to inform healthcare providers and the baby's pediatrician to develop an appropriate plan for the child's future care and management.

Smooth philtrum
The philtrum is the vertical groove between the nose and the upper lip. A flat or smooth philtrum is one of the classic facial characteristics of fetal alcohol syndrome (FAS). The Centers for Disease Control and Prevention diagnostic criteria for FAS require the presence of a smooth philtrum, in addition to a thin vermilion border of the upper lip and short palpebral fissures.
The prominence of the philtrum pillars is lost in individuals with FAS, with the pillars either completely absent or very faint and incompletely visible. This results in a smooth connection between the nose and upper lip. Animal studies have shown that even a single episode of consuming the equivalent of two alcoholic drinks during pregnancy may lead to fetal brain cell loss. This interference in brain development can lead to craniofacial abnormalities, including a smooth philtrum.
A smooth philtrum is one of the facial anomalies that can indicate FAS in newborns. Pediatricians and healthcare providers may be able to diagnose FAS at birth based on specific physical characteristics, including a smooth philtrum. However, the diagnosis of FAS can be challenging, and there is currently no direct test for FAS.
The identification of a smooth philtrum as a facial characteristic of FAS has been facilitated by the use of dense surface modeling and signature analyses of 3-dimensional facial photographs. These techniques help to visualize facial differences and establish predictive links between face shape and neurobehavior. By using these tools, researchers can identify strategies for recognizing facial dysmorphism across the fetal alcohol spectrum, even in individuals without classic facial characteristics.

Microcephaly
Fetal Alcohol Syndrome (FAS) is a permanent condition that occurs when a woman consumes any amount of alcohol during pregnancy. Alcohol use during this period can interfere with the baby's development, causing physical and mental defects.
One of the symptoms of FAS is microcephaly, which is characterised by a head circumference in the bottom 3rd percentile. Microcephaly is more commonly found in children with prenatal alcohol exposure, but it is not a sensitive marker as most exposed children have head circumferences above this clinical cutoff.
The presence of microcephaly in children with prenatal alcohol exposure is linked to reduced brain volume and cognitive function. However, the relationship between head circumference and brain volume weakens outside the normal range in prenatal alcohol exposure cases, indicating a complex interplay between skeletal and neural development.
The odds of microcephaly at birth are higher with higher paternal alcohol consumption before pregnancy, although this association is weaker for maternal alcohol consumption. This may be due to the absence of guidelines on safe drinking levels for men trying to conceive.
While microcephaly is a feature of FAS, it is difficult to diagnose. There is no single physical or cognitive finding that is pathognomonic, and partial expression of symptoms can occur with lesser degrees of alcohol use. Pediatric providers may suspect FAS based on the child's size, specific physical signs, and symptoms that develop through childhood, including abnormal facial features and small size at birth and throughout childhood.

Frequently asked questions
Fetal alcohol syndrome (FAS) is a permanent condition that occurs when a woman consumes any amount of alcohol during pregnancy. It is the most severe condition within a group of conditions called fetal alcohol spectrum disorders (FASDs).
Facial characteristics of FAS include small eye openings, a thin upper lip, a flat nose bridge, and a smooth philtrum (groove between the nose and upper lip). These features are not always present in all cases of FAS, and their severity can vary depending on the level of exposure to alcohol during pregnancy.
Yes, FAS can also cause growth deficits, including low body weight, short height, and microcephaly (a small head size). It can also lead to behavioural issues, cognitive impairments, and learning disabilities.
It is estimated that FAS may affect up to 5% of first graders in the United States, and up to 1% of the overall US population. However, the true prevalence may be underreported due to the associated guilt or stigma surrounding prenatal alcohol exposure.
No, FAS cannot be detected by ultrasound scans during pregnancy. Diagnosis of FAS typically occurs after birth based on the infant's size, specific physical characteristics, and behavioural observations.
