Objective To analyze the effect of patients′ age, sex, height, and body mass index (BMI) on the impacted mandibular third molar surgery. Methods Patients who needed third molar extractions were selected. The correlation of patients′ age, sex, weight, height, BMI and operation time was determined by Spearman′s rank correlation coefficient analysis. Statistically significant variables were selected for linear regression analysis. Results A total of 370 patients were enrolled. Only patients′ age showed a statistically significant correlation with operation time (P<0.001). Linear regression analysis indicated that patients′ age contribute 30.8% risk of increased operation time (β= 0.308, P<0.001). Conclusion Patients′ age is an important factor for affecting the operative difficulty of the impacted mandibular third molar.
