Understanding Cleft Lip and Cleft Palate: Causes, Symptoms, and Treatment Options

Key Takeaways

  • These birth defects occur in 1 in 700 babies when facial tissues fail to fuse during weeks 6-10 of pregnancy, with cleft lip being more common in males and cleft palate more frequent in females.
  • Maternal folic acid supplementation of 400 micrograms daily before conception reduces risk by up to 25%, while smoking during pregnancy doubles the likelihood of occurrence.
  • Infants often require specialized feeding bottles and techniques since they cannot create proper suction for breastfeeding or standard bottle feeding due to the opening connecting mouth and nasal cavity.
  • Initial surgical repair typically occurs at 3-6 months for lip closure and 9-18 months for palate repair, with most children requiring 2-5 additional procedures through adolescence for optimal function.
  • Speech development is commonly delayed, with 75% of children needing speech therapy to address nasal-sounding speech patterns and articulation difficulties that persist even after surgical repair.

Cleft lip and cleft palate are facial differences that occur during fetal development. These conditions happen when the tissues in the mouth or lip area don't join together properly, resulting in a split or separation. While the exact causes are often unknown, a combination of genetic and environmental factors may play a role.

What Are Cleft Lip and Cleft Palate?

A cleft lip is a physical split in the upper lip, which can extend to the nose and upper jaw. A cleft palate is an opening in the roof of the mouth, involving the hard or soft palate. These conditions can occur together or separately and may affect one or both sides of the mouth.

Causes and Risk Factors

While the exact causes of cleft lip and palate are unknown, several factors may increase the risk:

  • Family history of cleft lip or palate

  • Exposure to certain medications or chemicals during pregnancy

  • Maternal smoking or alcohol consumption

  • Insufficient folic acid intake before and during pregnancy

Symptoms and Diagnosis

Cleft lip and palate can cause various symptoms, including:

  • Difficulty feeding

  • Delayed speech development

  • Ear infections and hearing loss

  • Dental and jaw misalignment

Diagnosis may occur during a prenatal ultrasound or through a physical exam after the baby is born.

Treatment Options

Treatment for cleft lip and palate typically involves surgery to close the openings and improve function. The timing and number of surgeries depend on the severity of the condition. Additional treatments may include:

  • Speech therapy

  • Dental and orthodontic care

  • Ear tubes to prevent infections and hearing loss

  • Feeding support and specialized bottles

Outlook and Support

With proper treatment and support, most children with cleft lip and palate can lead normal, healthy lives. A multidisciplinary team of healthcare professionals, including plastic surgeons, speech therapists, and orthodontists, work together to provide comprehensive care. Organizations like the American Cleft Palate-Craniofacial Association offer resources and support for affected families.

The Bottom Line

Early surgical intervention combined with coordinated care from plastic surgeons, speech therapists, and orthodontists typically achieves excellent long-term outcomes for both appearance and function. Most children with these conditions go on to live completely normal lives with proper treatment sequencing.
