This report aims to first present Integra as an adjunct to complex mandibular reconstruction for intraoral lining resurfacing, and to review the literature on the use of dermal matrices for mucosal resurfacing of the floor of the mouth.

Clinical Report:

A 62-year-old female patient with previous ablation surgery for squamous cell carcinoma of the floor of the mouth, presented with extrusion of the mandibular plate through the chin skin and serious tongue tethering. The patient was managed with a chimeric osseocutaneous free fibula flap to restore the mandibular bone and chin skin defect, followed by a second-stage reconstruction of the intraoral defect with bilayer Integra. Complete release of tongue tethering was achieved enabling normal speech and deglutition and allowing for dental rehabilitation.


Integra was safely used as an alternative for intraoral lining, in composite mandibular reconstruction, downgrading reconstructive demands and offering optimal functional results.
