Introduction

Cleft palate is a congenital deformity characterized by an opening or split in the roof of the mouth that occurs when the tissues of the palate do not fuse completely during fetal development. This defect can vary in severity from a small notch in the soft palate to a large gap extending through both the soft and hard palate, affecting the function and appearance of the oral cavity.

The cleft palate may occur alone or in conjunction with a cleft lip, which involves a fissure in the upper lip. Both conditions are among the most common birth defects globally, affecting approximately 1 in every 700 live births, although incidence rates vary by ethnicity and geographic location.

The condition impacts essential functions such as feeding, speech, hearing, and dental development, often resulting in complications like recurrent ear infections and difficulties with speech intelligibility. Fortunately, cleft palate repair surgery, coupled with a multidisciplinary care approach, allows most patients to achieve near-normal oral function and appearance.

This article delves into the causes, symptoms, diagnosis, treatment options, preventive strategies, possible complications, and lifelong management associated with cleft palate and its repair.

The formation of the palate occurs between the 6th and 9th weeks of embryonic development. During this period, two shelves of tissue grow on either side of the developing mouth and normally fuse in the midline. Failure of this fusion results in a cleft palate.

Genetic predisposition plays a significant role in cleft palate formation:

Familial inheritance: Children born to parents or siblings with clefts have a higher risk.

Chromosomal abnormalities: Certain chromosomal syndromes, such as Trisomy 13 or 18, are associated with cleft anomalies.
