Dynamic Cleft Maxillary Orthopedics and Periosteoplasty

Area of Science:

• Craniofacial Surgery
• Orthodontics
• Pediatric Plastic Surgery

Background:

• Cleft lip and palate repair outcomes have historically varied.
• A longitudinal study was initiated in 1985 to evaluate dynamic maxillary orthopedics and periosteoplasty.
• Previous preliminary data from 1998 indicated normal facial growth patterns in treated patients.

Purpose of the Study:

• To report 25-year follow-up data on patients treated with dynamic maxillary orthopedics and periosteoplasty.
• To assess the long-term impact of these techniques on midfacial growth and skeletal consolidation.
• To evaluate the necessity of secondary alveolar bone grafting and orthognathic surgery.

Main Methods:

• Longitudinal follow-up of 25 patients (20 unilateral, 5 bilateral clefts) from the initial cohort for 25 years.
• Continuous documentation including clinical assessments, orthodontic, radiographic, and cephalometric analyses.
• Evaluation of midfacial growth, alveolar bone consolidation, and need for secondary interventions.

Main Results:

• Continued vertical and horizontal midfacial growth observed over 25 years.
• Successful consolidation of the alveolus with minimal need for secondary alveolar bone grafting.
• Orthognathic surgery was required in only 2 of 5 bilateral cleft cases and none of the unilateral cases.

Conclusions:

• Dynamic maxillary orthopedics and periosteoplasty, despite some controversy, do not negatively affect facial growth.
• These techniques promote early structural normalization, including maxillary consolidation and oronasal fistula closure.
• Benefits include improved lip closure, balanced nasal aesthetics, and enhanced social integration for cleft patients.
