Cleft lip and palate: a review for dentists

Area of Science:

• Plastic Surgery
• Craniofacial Surgery
• Pediatric Surgery

Background:

• Primary closure of cleft lip and palate requires restoring nasolabial muscle insertions and soft tissue positions.
• Conventional surgical approaches often delay correction of postoperative sequelae until growth is complete, leading to disadvantages.
• Orolabial dysfunctions persisting after primary surgery can negatively impact facial growth and cause dentofacial imbalances.

Purpose of the Study:

• To emphasize the importance of accurate, symmetric, and functional reconstruction of nasolabial muscles during primary cleft lip and palate surgery.
• To highlight the detrimental effects of delayed surgical correction on facial development and harmony.
• To advocate for early surgical intervention to prevent secondary deformities.

Main Methods:

• Review of surgical principles for primary cleft lip and palate repair.
• Analysis of the impact of orolabial dysfunctions on craniofacial growth.
• Evaluation of long-term outcomes associated with delayed surgical correction.

Main Results:

• Inaccurate or incomplete reconstruction of nasolabial muscles during primary surgery can exacerbate existing dentoskeletal imbalances.
• Delayed correction of postoperative sequelae can lead to significant long-term deformities, including nasal obstruction, mouth breathing, and maxillary hypoplasia.
• Symmetric and functional reconstruction is crucial for achieving optimal facial harmony and preventing further growth disturbances.

Conclusions:

• Primary surgical correction of cleft lip and palate must prioritize accurate and functional reconstruction of nasolabial muscles.
• Early intervention is essential to mitigate the adverse effects of orolabial dysfunctions on craniofacial development.
• Comprehensive primary repair contributes to improved facial aesthetics and function, preventing secondary complications.
