Changes in bone remodeling after palatal surgery.

T Shinbashi, N O'Hata, Y Hayashi

Annals of Plastic Surgery

|March 1, 1985

Summary

Cleft palate surgery in infants can cause abnormal facial bone remodeling and growth inhibition. This study reveals significant internal bone changes and prolonged effects, especially after mucoperiosteum removal.

Area of Science:

Oral and Maxillofacial Surgery
Craniofacial Biology
Bone Remodeling

Background:

Infants with cleft palate often experience facial underdevelopment post-surgery.
Postoperative abnormal internal facial bone remodeling is a suspected consequence.

Purpose of the Study:

To investigate palatal bone remodeling changes after surgical repair.
To assess external bone growth inhibition following palatal surgery.

Main Methods:

Utilized microradiography and hard tissue labeling.
Examined large undecalcified ground sections of the entire palatal bone.
Employed four experimental groups for comprehensive analysis.

Main Results:

Surgery led to external bone growth inhibition.

Related Experiment Videos

Significant abnormal remodeling occurred within the interior of the palatal bone.

Mucoperiosteum removal resulted in prolonged, persistent changes.

Conclusions:

Palatal surgery induces both external growth restriction and internal bone remodeling abnormalities.
The extent and duration of bone changes are influenced by surgical procedures, particularly mucoperiosteum removal.
