Orofacial Clefts: A Common Congenital Anomaly

Orofacial clefts, also known as cleft lip and palate, are a type of birth defect that affects the formation of the mouth and lip during prenatal development. This condition occurs when the tissue making up the upper lip and/or the roof of the mouth doesn't join completely before birth, resulting in an opening or split.

Types of Orofacial Clefts

There are three main types of orofacial clefts:

• Cleft Lip: A gap or groove in the upper lip that occurs when the tissue making up the lip doesn't fuse properly during embryonal development.
• Cleft Palate: An opening or split in the roof of the mouth that occurs when the tissue doesn't close fully during development in the womb.
• Cleft Lip and Palate: A combination of both cleft lip and cleft palate.

Causes and Risk Factors

Most orofacial clefts are caused by an interaction between genetic and environmental factors. Some risk factors include:

• Family history: Having a family history of orofacial clefts increases the risk.
• Genetic mutations: Certain genetic mutations can increase the risk of developing an orofacial cleft.
• Environmental factors: Exposure to certain environmental toxins during pregnancy may also contribute to the development of an orofacial cleft.

Prevalence and Treatment

Orofacial clefts are one of the most common congenital anomalies worldwide, affecting approximately 1 in every 700 births. Treatment for orofacial clefts typically involves surgery to close the opening or split, followed by speech therapy and other supportive care to ensure proper healing and development.

Common Signs and Symptoms of Orofacial Cleft

Orofacial cleft, which includes cleft lip and cleft palate, can manifest in various ways, affecting the upper lip and/or the roof of the mouth. Some common signs and symptoms include:

• Visible gap: A noticeable separation or indentation in the upper lip and/or palate, ranging from a small indentation to a large gap that may extend to the nose [1].
• Ear infections and hearing problems: Children with cleft lip or palate are more likely to experience ear infections and hearing loss due to Eustachian tube dysfunction [2].
• Speech and language delays: As they grow older, individuals with cleft lip or palate may face challenges with speech and language development [3].
• Trouble breathing: In some cases, the cleft can cause respiratory issues, particularly if it affects the nasal passages or sinuses.
• Frequent ear infections: The Eustachian tube dysfunction associated with cleft lip or palate can lead to recurring ear infections.
• Hearing loss: Permanent hearing impairment may occur due to chronic ear infections and Eustachian tube problems [2].
• Eye problems: Some individuals with cleft lip or palate may experience eye-related issues, such as dry eyes or vision problems.
• Speech problems: Difficulty articulating words and sounds can be a challenge for those with cleft lip or palate.

It's essential to work with a care team experienced in managing craniofacial conditions like cleft lip and palate to ensure proper treatment and support.

Diagnostic Tests for Orofacial Clefts

Orofacial clefts, including cleft lip and palate, can be diagnosed using various diagnostic tests. Here are some of the common tests used to diagnose these conditions:

• Ultrasound: A routine ultrasound during pregnancy can detect orofacial clefts, especially cleft lip [5]. After birth, an ultrasound or physical examination by a doctor can also diagnose changes in the face and mouth that may indicate a cleft [6].
• Blood tests: Blood tests, such as a complete blood count (CBC), may be ordered to rule out other conditions that could cause similar symptoms [7].
• X-rays: X-rays of the face and jaw may be taken to assess the extent of the cleft and plan for surgical repair.
• Specialized tests: In some cases, additional specialized tests such as chromosomal studies or laboratory tests may be ordered to determine if there are any underlying genetic conditions that contributed to the development of the cleft.

It's essential to note that a diagnosis of an orofacial cleft is usually made by a healthcare provider based on a combination of physical examination, medical history, and diagnostic test results.

Treatment of Orofacial Clefts

While there are no specific "drugs" that can treat orofacial clefts, certain medications may be used to manage related complications or conditions.

• Prenatal exposure: Some studies have investigated the potential link between prenatal exposure to certain medications and an increased risk of orofacial clefts. For example:

  • A study by EH Puhó (2007) [1] confirmed the orofacial cleft inducing effect of phenytoin, carbamazepine, oxytetracycline, and thiethylperazine.
  • However, another study by H Dolk (2016) [9] found that lamotrigine, a medication commonly used for epilepsy and bipolar disorder, has a good teratogenic safety profile relative to other antiepileptic drugs.

• Postnatal treatment: Treatment of orofacial clefts typically involves surgery and may include speech therapy and dental work. According to the American Cleft Palate-Craniofacial Association (ACPA), treating cleft lip and palate can be a long-term process that requires years of specialized care [3].

• Medications for related conditions: In some cases, medications may be used to manage related complications or conditions associated with orofacial clefts. For example:

  • Speech therapy may involve the use of certain medications to help manage speech difficulties.
  • Dental work may require the use of antibiotics or other medications to prevent infection.

It's essential to note that treatment plans for orofacial clefts are highly individualized and depend on the severity of the condition, as well as the child's age and overall health. A multidisciplinary team of healthcare professionals will work together to develop a comprehensive treatment plan tailored to each child's unique needs [10].

Differential Diagnosis of Orofacial Cleft

Orofacial cleft (OFC) is a complex condition that requires accurate diagnosis to determine the underlying cause and develop an effective treatment plan. The differential diagnosis of OFC involves identifying other conditions that may present with similar symptoms or characteristics.

According to various studies, the differential diagnosis of OFC should include:

• Chromosomal disorders: Such as trisomy 13, trisomy 18, and Wolf-Hirschhorn syndrome, which are characterized by orofacial clefts among other features [7].
• Genetic syndromes: Such as Oro-facio-digital syndrome (OFDS), which presents with orofacial features like cleft palate, bifid tongue, hypodontia, and other anomalies [15].
• Popliteal pterigium syndrome: A rare condition characterized by popliteal webs, cleft lip/palate, lower lip pits, and other anomalies of the genitor-uterine tract [15].

It is essential to note that a comprehensive differential diagnosis should also consider the presence of associated malformations, which can help differentiate between isolated OFC and one with other underlying conditions.
