Objective:
This study examined prospectively the functional outcomes of a cohort of patients who have undergone mandibulectomy and primary fibular free flap reconstruction, with particular emphasis on longitudinal comparison of the preoperative function with that in the postoperative and post-radiation therapy time periods.
Methods:
Speech and swallowing data were gathered at three evaluation times (preoperatively, pre-radiation therapy, and post-radiation therapy) for patients treated for oral cavity cancer with mandibular resection and reconstruction with a fibular free flap. Single words and sentences were recorded and analyzed for speech intelligibility. Modified barium swallows of liquid, pudding, and cookie consistencies were analyzed and graded for problems in the oral preparatory and oral phase according to the University of Chicago Center for Speech and Swallowing Disorders Oropharyngeal Mobility Data Form.
Results:
There was no significant difference across any of the evaluation times for single-word or sentence intelligibility. The swallowing data showed no instances of post-treatment aspiration or laryngeal penetration. There were also no significant differences in any of the swallowing parameters across treatment times.
Conclusions:
Osteocutaneous fibular free flaps are an excellent reconstructive option for mandibular and floor of the mouth defects.
