목적: To analyze the frequency and characteristics of facial asymmetry in patients with deviated nose and to identify predictable parameters to detect types and severity of facial asymmetry. 방법:Using frontal photographs, presence of facial asymmetry and types of deviated nose were judged and measured 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. 결과: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 measurement parameters, 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. 결론:Facial asymmetry was more common in the patients with deviated nose comparing to the controls, and mixed type facial asymmetry was often detected. This study suggests that the etiology of deviated nose may be a developmental defect causing growth discrepancy of facial bony skeleton from both sides. Also, suggested objective anthropometric measurements in this study can be used for obtaining appropriate preoperative facial assessment.
