Ten-Year Cephalometric Comparison of Patients With Cleft Palate who Received Treatment With Active or Passive Pre-surgical Orthopedic Devices

Abstract

Background

Pre-surgical orthopedic (PSO) devices can be used in the management of patient with cleft lip/palate (CL/P) to narrow the alveolar gap (AG) prior to lip surgery. There are few studies comparing these 2 devices. The objective of this work was to compare the effects of active and passive PSO devices on facial growth in a single surgeon's cohort of patients with CL/P over a 10-year period.

Methods

A retrospective review of all patients with CL/P in a single surgeon's practice from 2002 to 2018 was performed. Preoperative measurements of AG size were done using electronic calipers on patient molds. Patient radiographs were taken at 5 and 10 years of age and cephalometric landmarks were plotted using specialized software. Independent sample t-tests were used to compare means for maxillary, mandibular, vertical, and dento-alveolar growth parameters.

Results

Twenty patients with an active device and 23 patients with a passive device were included. No differences were observed in the basic demographic information between the two groups. At the time of lip repair, patients with a passive device had significantly larger horizontal AGs (P < .01), but by the time of palate repair, there was no difference between the two groups (P = .94). There was no significant difference in any growth measurements between the active and passive device groups at 5 and 10 years.

Conclusions

Despite closing the AG more quickly, patients treated with an active device have no significant difference in facial growth at 10 years compared to patients treated with a passive device.
