Comparison of surgical treatment and conservative treatment for mandibular condylar fractures

Abstract

Objective To compare the therapeutic effect and complications of surgical treatment and conservative treatment for mandibular condylar fractures. Methods 100 cases of mandibular condylar fractures were selected as the research subjects.According to the different treatment method, the patients were divided into the observation group and the control group, 50 cases in each group.The observation group was treated by operation, and the control group was treated with conservative treatment.The therapeutic effect, mouth opening of before and after treatment, the change of movement and lateral movement, and complications were observed and compared between the two groups. Results The excellent and good rate of the observation group was 88%, compared with the control group of 86%, the difference was not statistically significant (P>0.05).12 months after treatment, mouth opening, protrusion movement and lateral movement of two groups were significantly improved than treatment after 6 months[(38.23±9.65) vs (35.98±9.65), (37.98±9.65) vs (35.43±8.76), (7.98±1.66) vs (7.21±1.03), (7.87±1.43) vs (6.98±1.06), (8.96±1.32) vs (8.06±1.06), (8.86±1.25) vs (8.86±1.25)], the differences were statistically significant (t=2.87, 3.43, 3.43, 3.43, 4.17, 4.21, all P 0.05). The incidence rate of postoperative complications including limitation of mouth opening, opening deflexion, joint symptoms, injury of facial nerve, parotid salivary fistula and bite axis disorder between two groups had no significant difference (16.0% vs 14.0%, P>0.05). Conclusion Surgical treatment and conservative treatment are the common methods for treatment of mandibular condylar fractures, and the effect of surgical treatment is better than conservative treatment.
