**8. Conclusions**

Head and neck cancer requires a multidisciplinary approach to face diagnosis, treatment, and rehabilitation. Oral cancer is one of the most frequent sites in which functional disturbance due to the primary tumor invasion or destruction of normal tissue or its treatment like extensive surgery, chemotherapy, radiation, or the combination of them ends in functional and cosmetic disturbance that impacts quality of life. Especially surgery creates a defect that alter function in terms of deglutition, swallowing, speech, breathing, and esthetics. Immediate reconstruction is necessary and must be intended to restore or improve rehabilitation.

Reconstruction calls to assay factors related to the patient, to the tumor defect, and to the team expertise. The best and simplest reconstructive option must be offered to refurbish as similar as possible to a new normal functional tissue, as well as guaranteeing patient survival with low morbidity, without neglecting the reasonable employment of technical and economic resources. Critical analysis must be done in every case to decide from a primary close to escalate up to a micro vascularized free flap.
