Dentofacial self-perception and social perception of adults with unilateral cleft lip and palate

The aim of this study was to investigate the influence of facial asymmetry on how an adult population with unilateral cleft lip and palate (CLP) perceived themselves and were perceived by others.

3D facial data of 30 adult patients with cleft lip and palate (CLP) was scanned and standardized extra- and intraoral photographs were taken. The measured degree of 3D asymmetry was computed for the entire face, midface and lower face. Subjective estimates regarding facial symmetry, attractiveness as well as satisfaction and a desire or indication for further treatment were surveyed by means of a questionnaire filled out by patients and an assessment group (10 orthodontists, 10 oral and maxillofacial (OM) surgeons, 15 laypersons).

The study's results show that the largest degree of asymmetry was found in the midface of CLP patients. The vast majority of the patients were dissatisfied with their facial appearance, and patients, experts and laypersons expressed great interest in and a need of correction. We observed tangible incongruence between how the patients perceived their own faces and how others perceived them.

Asymmetry, especially in the midface, appears to detract from how facial appearance is self-perceived and perceived by others, which explains the primary desire for or need of nose correction. The self-perception of patients affected by CLP does not correlate with objective results or how others perceive them. Clinicians should be open to adult patients' requests for correction, but the patient's self-perception should also be critically explored.
