Facial and orbital asymmetry in oculofacial surgery patients.

Facial symmetry traditionally has been associated with beauty, and we typically strive for symmetry in surgery. However, the subtle degrees of asymmetry are natural and perhaps even more common than perfect symmetry. We retrospectively reviewed photographs of 100 oculofacial surgery patients without history of unilateral or orbital pathology or diplopia to describe the occurrence of facial asymmetries, including larger hemiface, hemiface with stronger seventh cranial nerve (measured by smile excursion and increased dynamic periocular rhytides during smile), hemiface with more pronounced rhytides at rest, difference in vertical globe height compared to interpupillary distance (IPD), higher earlobe, and higher lip. We found that most patients had static and dynamic facial asymmetry. Our data highlight the importance of counseling patients about preexisting facial asymmetry and establishing normative values for asymmetry.
