Abstract
Objective:
To investigate the postoperative complication rates of LeFort 1 maxillary advancement surgery in cleft patients when performed by a single surgeon over a 5-year period.
Design:
A retrospective case note review of 79 cleft palate patients.
Setting:
All surgery was performed by a single oral and maxillofacial surgeon in a tertiary care center.
Participants:
All cleft palate patients over 17 years of age who opted for surgical correction of maxillary hypoplasia with a LeFort 1 between 2010 and 2015. Patients required full surgical and clinical records.
Interventions:
Complete surgical advancement of the maxilla ranging from 2.0 to 18.0 mm performed by conventional osteotomies (87%) or distraction osteogenesis (13%).
Main Outcome Measure(s):
Postoperative patient- and clinician-reported complications at set-interval follow-up appointments.
Results:
Twenty-one patients (26.58%) reported no complications; 11 postoperative complications were identified in the remaining cohort. Temporary paresthesia of the infraorbital nerve was the most common complication (53.16%) followed by infection (13.92%). Other complications included relapse (11.39%), maxillary instability (6.33%), velopharyngeal impairment (6.33%), nasal obstruction (5.06%), chronic sinusitis (3.80%), bony dehiscence (1.27%), gingival necrosis (1.27%), partial necrosis of the maxilla (1.27%), and loss of tooth vitality (1.27%).
Conclusions:
LeFort 1 maxillary advancement surgery in cleft palate patients is associated with a wide range of postoperative complications, most commonly temporary paresthesia of the infraorbital nerve. Detailed, informed consent is essential prior to surgery.
