Mandibular reconstruction has attained adequate morphological outcomes. However, some patients encounter difficulties in oral function and limited mandibular movements. An objective: evaluation has seldom featured actual kinetic measurements after mandibular reconstruction.
Thirty patients who underwent mandibular reconstruction using bony free flap were enrolled in the study. Twenty-two patients were recruited after surgery and compared to a control group of 8 healthy subjects; 8 patients underwent both pre and postoperative evaluations. For each patient, a kinesiographic scan was obtained, recording maximum mouth opening, maximal laterality, and maximal protrusion.
All postoperative kinesiographic evaluations were performed at least 6 months after surgery to ensure complete healing. In the first group of 22 patients, all measured movements were less than those of healthy controls, in particular maximum mouth opening. In the second study group (pre and postoperative evaluation), the postsurgical values did not achieve the control ones, but were no less than the preoperative values, granting adequate functional outcomes.
The kinesiograph appears useful for objectively recording the functional outcomes in patients who have undergone mandibular reconstruction. The postoperative jaw movements were acceptable, ensuring a sufficient functional recovery.
