latham appliance
Pronunciation: LAY-thum
Presurgical orthopedic device used to align cleft lip and palate segments before surgical repair.
Full Definition
The Latham appliance is a presurgical infant orthopedic (PSIO) device designed to gradually reposition cleft lip and palate segments into better anatomical alignment before surgical closure. Named after Dr. Ralph Latham, this appliance uses gentle, continuous pressure to move the maxillary segments and reduce the width of cleft defects. The device is typically placed in the first few weeks of life and adjusted regularly over several months. By improving the position of cleft segments, the Latham appliance can reduce surgical complexity, improve aesthetic outcomes, and potentially reduce the need for secondary procedures.
Usage
