Bilateral cleft lip and palate: improved maxillary and dental development

Area of Science:

• Craniofacial surgery
• Pediatric dentistry
• Orthodontics

Background:

• Maxillary growth deficiency is a persistent challenge in children with repaired cleft lip-cleft palate.
• Limited research exists on preventing this deficiency.
• Early diagnosis of maxillary growth issues necessitates evaluating new treatment protocols.

Purpose of the Study:

• To assess the efficacy of a novel surgical protocol for bilateral cleft lip-cleft palate repair.
• To evaluate its impact on dental and maxillary development in early childhood.

Main Methods:

• A new, less invasive hard palate repair technique using nasal septum mucosa was employed.
• Lip repair was performed at 18 months, later than the previous 8-month standard.
• Outcomes were compared between 12 new cases and 12 historical controls using dental occlusion and cephalometric radiography at age 5.

Main Results:

• The new protocol significantly reduced incisor crossbite (33% vs. 83%) and cuspid crossbite (50% vs. 100%).
• Cephalometric analysis revealed improved maxillary length, prominence, and ANB angle in the new treatment group.
• These findings indicate enhanced maxillary development compared to the previous method.

Conclusions:

• The novel surgical approach demonstrates improved dental and maxillary development outcomes at age 5.
• This protocol offers a promising strategy for managing bilateral cleft lip-cleft palate.
• Further research can validate long-term benefits.
