Cleft palate is a congenital deformity characterized by an opening or split in the roof of the mouth that occurs when the tissue doesn’t fuse properly during fetal development. Accurate classification of cleft palate is essential for planning effective treatment, understanding prognosis, and providing appropriate counseling to families. Over the years, various classification systems have been developed to categorize clefts based on their location, extent, and complexity.
One of the most widely used systems is the Veau classification, established by Victor Veau in the early 20th century. It divides cleft palate deformities into four main groups. Veau I involves isolated soft palate clefts, where only the soft tissue of the soft palate is affected. Veau II includes clefts that extend into the hard palate but do not involve the alveolus or the teeth-bearing part of the maxilla, representing incomplete clefts. Veau III describes complete unilateral clefts that extend through the soft and hard palate and involve the alveolus on one side, often affecting the lip as well. Veau IV encompasses bilateral complete clefts that affect both sides, involving the soft palate, hard palate, and alveolar ridges.
Another important classification is the Bardach system, which provides a more detailed understanding by subdividing clefts into more specific categories based on the anatomical structures involved. This system considers the extent of the cleft from the soft palate through the hard palate, alveolar ridge, and lip, helping surgeons plan precise surgical interventions.
The Houston classification offers a different perspective by emphasizing the embryological origin of the cleft and categorizing them based on developmental failure points. It helps in understanding potential associated

anomalies, which are common in syndromic cases.
More recently, the Crawford classification has gained popularity, especially for surgical planning, as it categorizes clefts into incomplete and complete types, as well as by their occurrence on the unilateral or bilateral sides. It also considers the presence of submucous clefts—those covered by mucosa, often missed during initial examination but significant for speech development.
In addition to these systems, clinicians often describe clefts based on their specific location: soft palate only, hard and soft palate, or involving the alveolus and lip. This descriptive approach helps in individual case assessment and tailoring treatment strategies.
Understanding the nuances of cleft palate classification is vital for multidisciplinary teams involving surgeons, speech therapists, orthodontists, and geneticists. Precise classification guides surgical repair techniques, predicts potential complications, and informs long-term rehabilitation plans. As research advances, classification systems continue to evolve, integrating genetic and imaging data to provide a comprehensive understanding of each case.
In summary, the classification of cleft palate is a cornerstone of effective management. From the traditional Veau system to modern, detailed approaches, these classifications help clinicians deliver personalized care, improving outcomes and quality of life for patients.
