ABSTRACT
BACKGROUND:
In severe cases of maxillary hypoplasia, Le Fort I distraction may be required for treatment. This study describes our experience with internal distraction devices and assesses our outcomes in patients with a negative overjet on average >15âmm.METHODS:
A retrospective review of patients with a history of cleft lip and/or palate who underwent Le Fort I distraction at our institution from 11/2007-11/2017 was performed. Data regarding demographics, procedural details and outcomes were collected and analyzed.RESULTS:
Twenty patients, 13 (65.0%) male and 7 (30.0%) female, were included. All (100%) patients had a history of cleft lip and/or palate and 2 (10.0%) of them had associated syndromes. All 20 patients underwent internal distraction. The average age at surgery was 17.8 years (range 15.2-20.7, SD 1.6 years). The average preoperative negative overjet was 19.27âmm (range 10-30, SD 5.63âmm). The mean total distraction length was 15.3âmm (range 0-30, SD 6.72âmm). There were no intraoperative complications, however, there were a total of 4 (20.0%) postoperative complications, 2 of which required reoperation due to device malfunction or displacement. 14 (70.0%) patients had repeat procedures to complete occlusal correction or correct relapse.CONCLUSIONS:
Maxillary distraction alone was insufficient for correction of maxillary discrepancies averaging >15âmm. Instead, it's utility may be in positioning the maxilla for a more viable final advancement and fixation procedure, rather than being solely responsible for achieving normal occlusion during distraction.
