[Internal fixation of mandibular comminuted fracture with mini-titanium plate: a retrospective study of 21 cases].

PURPOSE: To investigate the value of internal fixation in management of mandibular comminuted fracture with mini-titanium plate.

METHODS

Twenty-one patients with mandibular comminuted fracture treated in Stomatology Hospital of Shenyang from March 2017 to February 2018 were enrolled, the patients received internal fixation with mini-titanium plate. The lower mandibular margin, upper mandibular margin and middle outer cortex were fixed respectively. The postoperative fracture healing and adverse reactions were recorded and analyzed.

RESULTS

All patients achieved bone healing within 3 months after surgery, with an average duration of (1.53±0.36) months. Among 21 patients, six patients (28.57%) had minimal occlusion, and 1 patient (4.76%) had local infection. No microtitanium plate fracture, persistent pain, limited mouth opening, tooth injury, facial nerve injury or nonunion were found.

CONCLUSIONS

Internal fixation with mini-titanium for comminuted mandibular fracture patients without bone defects has the advantages of good postoperative fracture healing, short healing time and few adverse reactions.
