사비환자에서 관찰되는 안면비대칭의 빈도와 특징 : Frequency and Characters of Facial Asymmetry in Deviated Nose Patients

다국어 초록 (Multilingual Abstract)

Objectives/Hypothesis: Facial asymmetry is often detected in patients with deviated nose seeking rhinoplasty, leading to failure of successful correction. In this study, we aimed to analyze the frequency and characteristics of facial asymmetry in patients with deviated nose.
Methods: The retrospective review of preoperative photographs of 152 patients who underwent rhinoplasty for deviated nose was conducted. The incidence of facial asymmetry was compared with 60 control subjects undergoing septoplasty without external deviation of the nose.
Using frontal photographs, presence of facial asymmetry and types of deviated nose were judged by two observers. Types of facial asymmetry were categorized into four types by affected subunits of the face and the shapes of deviated nose were also classified into five different types. Whether the direction of bony deviation is corresponding to the side of smaller looking face is also examined. Anthropometric measurements were performed.
Results: Facial asymmetry was more commonly found in patients with deviated nose (n=84 (55%)) than the control subjects (n=19 (32%)) (P=0.042). Mixed type facial asymmetry was the most common in the patient group. Among the anthropometric measurements, the distance between the midpoint of interpupil line to the most prominent malar point, lateral canthal angle, lateral alar angle, lip margin angle, and tilted chin angle of the patient group was significantly different from those of the control group (p<0.05). There was no difference in the incidence of asymmetry in each type of deviation. However, bony dorsum tended to deviate towards the smaller side of face.
Conclusions: Facial asymmetry was more common in the patients with deviated nose comparing to the controls, and mixed type facial asymmetry was often detected. The results of our study suggest that the etiology of deviated nose may be a developmental defect in facial bony skeleton.
