Static and dynamic changes of natural head position improve vertical eye canting of patients with non-syndromic asymmetric facial deformities after orthognathic surgery.

ABSTRACT:

Objective

By combining static and dynamic methods of obtaining natural head position, this study examined whether compensatory head tilt in patients with non-syndromic asymmetric facial deformities contributes to of pseudo-"vertical eye canting".

Methodology

Patients with non-syndromic asymmetric facial deformities patients and symmetric dento-maxillofacial deformity who met the inclusion and exclusion criteria were divided into observation and control groups. Static photographs were measured to analyze the static head position of the subjects in each follow-up period; dynamic natural head positions of the subjects in different states in each period were recorded by posture sensors for dynamic analysis. Intergroup and intragroup changes were analyzed with Mann-Whitney U-test
