Mandibular widening in hemifacial microsomia: A roentgen stereometric study of 11 patients with the aid of metallic implants
(2012) In American Journal of Orthodontics and Dentofacial Orthopedics 141(4). p.88-91- Abstract
- Introduction: Our objective was to study mandibular widening in untreated subjects with hemifacial microsomia. Methods: From the 3-dimensional files at the Department of Plastic and Reconstructive Surgery, Skane University Hospital in Malmo, Sweden, data of 11 subjects (3 girls, 8 boys) with hemifacial microsomia were retrieved. Their age range was 9 years 2 months to 13 years 2 months at the first examination. The mean observation period was 5 years 2 months. Each subject was studied by roentgen stereophotogrammetry with the aid of metallic implants. Results: A significant widening of the mandible was found, with a mean total change of 0.31 mm (range, 0.08-0.79 mm) and a mean annual change of 0.07 mm (range, 0.03-0.12 mm). In 2 subjects,...

In 2 subjects, narrowing of the mandible was found: -0.16 and -0.23 mm. Conclusions: The mandible got wider during adolescence in 9 of our subjects with hemifacial microsomia but to a lesser extent than has been reported in subjects without hemifacial microsomia and from ordinary orthodontic clinics. Sex difference was not addressed. It was suggested that chewing (forces and patterns) was responsible for the mandibular widening in our subjects; this is in line with previous research.
