REVIEW THE CLINICAL CHARACTERISTICS OF PATIENTS WITH FACIAL ASYMMETRY
Main Article Content
Abstract
Objective: Review the clinical characteristics of patients with facial asymmetry. Subjects: The study was carried out from February 2022 to December 2022, using a cross-sectional descriptive study method of 33 patients aged 16 years old who came to the clinic for facial asymmetry at Hanoi Cental Odonto-Stomatology Hospital, based on the patient questionnaire, clinical examination, analysis of straight face and smiley face images. Results: The average age of male participants in the study was 20.2 ± 4.02 years old and female was 23.1 ± 8.38 years old, 100% of patients with facial asymmetry had chin deviation, in which patients has a high rate of left chin deviation 70.6%, there is no difference between men and women with chin deviation (p>0.05). The proportion of patients participating in the study was 87.9% and 69.7% respectively. In 33 patients participating in the study, 21.2% of patients were evaluated for unilateral crossbite, 48.5% of patients with bilateral crossbite and 30.3% without this symptom. The average chin deviation is 9.84±5.51mm. Mean deviation of soft tissue horizontal asymmetry and deviation of mouth angle are 10.07±7.9mm and 3.28±2.27mm, respectively. The rate of chin deviation of patients with facial asymmetry with class I, II, and III malocclusion is 15.2%, respectively; 9.1% and 75.8%. Class III malocclusion is the most common. The proportion of patients with chin deviation, the mandibular midline will mostly be deviated (84.9%), a statistically significant difference was found between the group of patients with deviated chin and deviated mandibular midline. (p<0.01). Gender factor did not affect the asymmetry on the patient's face (p<0.05). The habit of pushing the tongue is a factor affecting the patient's facial deviation. Conclusion: Patients with facial asymmetry have 100% of the chin deviation. In the majority of 84.9% cases with chin deviation, the mandibular midline is also deviated (p<0.01). Gender factor did not affect the asymmetry on the patient's face (p<0.05). The habit of pushing the tongue is a factor affecting the patient's facial deviation.
