Early palatal changes in complete and incomplete cleft lip and/or palate

Area of Science:

• Craniofacial development
• Pediatric dentistry
• Plastic surgery

Background:

• Cleft lip and/or palate (CLP) is a common congenital condition affecting facial structure.
• Understanding early palatal development is crucial for effective treatment strategies.

Purpose of the Study:

• To analyze palatal morphology and dimensions in infants with various forms of CLP from birth to 3 months.
• To compare palatal growth in CLP infants with a control group of normal infants.
• To evaluate the impact of preoperative orthopedics on palatal growth.

Main Methods:

• Dental casts were used to assess palatal shape and dimensions in 128 CLP infants and 68 controls.
• Reproducible reference points were utilized for accurate measurements.
• Analysis included different types of complete and incomplete clefts.

Main Results:

• Normal palates exhibited significant growth, changing from round to oval arch forms, primarily in the sagittal direction.
• CLP infants' palates differed significantly based on cleft type: elongated arches in cleft lip and alveolus/bilateral CLP, wider arches in unilateral CLP/cleft palate.
• Incomplete clefts showed less distinct deviations from normal compared to complete clefts.
• Preoperative orthopedics appeared to restrict rather than stimulate palatal growth.

Conclusions:

• Palatal growth and morphology in early infancy are significantly influenced by the type and extent of cleft lip and/or palate.
• Preoperative orthopedic interventions may negatively impact natural palatal development.
• Further research is needed to optimize interventions for CLP patients.
