Abstract
This article reports that mandibular skeletal asymmetry is not evident in a group of adults with posterior unilateral crossbite when compared with an adult control group. Furthermore, the authors claim that posterior crossbite is due to increased width of the mandible and not a result of transverse deficiency of the maxilla. This study makes use of posteroanterior (PA) radiographs, in preference to previously used submental vertex radiographs, as used by Lam et al 1 Lam P.H. Sadowsky C. Omerza F.
