The book "Fisura Labio Alvéolo Palatina: Nueva Metodología de Intervención Fonoaudiológica" by Ana Beatriz Tamashiro addresses cleft lip and palate, a congenital condition. Key points: Cleft lip and palate are facial malformations occurring during embryonic development. It happens when the lip and palate don't fuse properly in the first nine weeks of pregnancy. Genetic and environmental factors can contribute to its development. The condition can affect the lip, nasal base, alveolar ridge, and hard and soft palate. Treatment often involves a multidisciplinary approach, including speech therapy. Surgery is typically required, sometimes in multiple stages. It's the most common craniofacial defect, with varying prevalence across populations. Speech and hearing can be affected, requiring intervention.
