Veau classification of cleft lip and palate

The Veau classification system is a widely used system for classifying cleft lips and palates based on the anatomical features of the cleft. It is important for understanding the presentation of these conditions and planning surgical management. The classification consists of four main types: ### Veau Classification System 1. **Veau Class I**: - **Description**: A cleft lip only, which can be unilateral or bilateral, but does not extend into the palate. 2. **Veau Class II**: - **Description**: A unilateral cleft lip and an incomplete cleft palate that does not extend through the hard palate. The cleft may involve the soft palate but does not connect to the other side of the mouth. 3. **Veau Class III**: - **Description**: A unilateral cleft lip with a complete cleft palate extending through the hard and soft palates. This means there is a full separation between the oral cavity and nasal cavity on one side. 4. **Veau Class IV**: - **Description**: A bilateral cleft lip with a complete cleft palate. This condition involves both sides of the lip and extends through both the hard and soft palates. This classification helps clinicians communicate about the severity and specifics of cleft conditions and guides treatment planning, including surgical interventions. Each type may have different implications for feeding, speech development, and overall management. Update (2024-09-06): The Veau classification system is used to categorize cleft lip and palate based on the anatomical presentation of these conditions. This classification helps in planning surgical intervention and understanding the severity of the clefts. The classification is divided into four types: 1. **Veau Type I**: This type refers to a simple unilateral or bilateral cleft of the lip, with no involvement of the alveolus or palate. The cleft is typically confined to the lips. 2. **Veau Type II**: This type involves a cleft of the primary palate (lip and anterior alveolus) but does not extend into the hard or soft palate. It can be unilateral or bilateral. 3. **Veau Type III**: This type features a cleft that includes both the primary palate and the hard palate but spares the soft palate. This may also be unilateral or bilateral. 4. **Veau Type IV**: This is the most severe form, characterized by a complete cleft that extends through both the primary and secondary palate, involving the hard palate, soft palate, and often resulting in a bilateral cleft lip. The Veau classification aids in the diagnosis and treatment planning for patients with cleft lip and palate, ensuring that healthcare providers are on the same page regarding the extent of the cleft and the necessary surgical interventions.
