Abstract Objective To analyze the effect of retromandibular transparotid anterior masseter approach combined with absorbable bone plate in the treatment of middle and low condylar process fractures. Methods A total of 45 patients with middle and low condylar process fractures treated in Xingtai People’s Hospital of Hebei Province from January 2019 to February 2022 were selected as the research objects. According to the random number table method, they were divided into control group (23 cases) and observation group (22 cases). The control group was treated with the traditional incision around the mandibular angle combined with titanium plate nail fixation, and the observation group was treated with the retromandibular transparotid anterior masseter approach combined with absorbable bone plate. The incidence of postoperative complications and efficacy were compared between the two groups, and the oral activity of the two groups before operation and three, six months after operation were compared. Results There was no significant difference in the incidence of facial nerve injury, mouth deviation, and sialosyrinx between the two groups (P＞0.05). The incidence of postoperative incision infection in the observation group was lower than that in the control group (P＜0.05). The amplitude of mouth opening, mandibular forward movement, and mandibular lateral movement in the two groups at three and six months after operation were higher than those before operation, and those at six months after operation were higher than those at three months after operation (P＜0.05). The amplitude of mouth opening, mandibular forward movement, and mandibular lateral movement in the observation group were higher than those in the control group at three and six months after operation (P＜0.05). The clinical efficacy of the observation group was better than that of the control group (P＜0.05). Conclusion The retromandibular transparotid anterior masseter approach combined with absorbable bone plate in the treatment of middle and low condylar process fractures can improve the therapeutic effect, reduce postoperative incision infection, and improve the range of oral activity.
