What procedure is scheduled for a congenital defect where the hard palate fails to fuse during fetal development?

The procedure indicated for a congenital defect where the hard palate fails to fuse during fetal development is palatoplasty. This surgical intervention specifically addresses issues associated with a cleft palate, which can significantly affect feeding, speech, and overall facial aesthetics.

During the procedure, the surgeon repairs the split or opening in the hard palate to restore normal anatomy and function. This is aimed at improving both the structural integrity of the mouth and the patient's ability to speak and eat effectively.

Cheiloplasty refers to the repair of a cleft lip, which is a separate condition, and while it involves a related anatomical area, it does not address the issues associated with a cleft palate. Repair of cleft lip might be performed in conjunction with palatoplasty, but it is not the appropriate procedure for addressing a defect in the hard palate itself. A lingual frenectomy involves the removal of the frenulum under the tongue, which is unrelated to the fusion of the hard palate. In summary, palatoplasty is the directly applicable procedure for correcting a cleft palate, making it the correct choice for the scenario presented.
