Tumor resection will be star first this accomplish with 1- 2 cm safety margin, Simultaneous neck dissection will be performed in all patient.

Flap dissection begins from the opposite side of the pedicle in the subplatysmal plane. Then the level 1a is dissected, the distal facial artery and facial vein to the branching point of the submental pedicle are ligated. The anterior belly of the digastric muscle on ipsilateral to the pedicle and strip of mylohyoid muscle will dissected off the mandible and the hyoid bone and included with the flap. This results in complete mobilization of the flap.A tunnel will be created between the defect and the donor site and the skin paddle of the flap will be transported through it intraorally and the flap is insetted.

Under general anesthesia the tumor will be resected with Preserving floor of mouth mucosa as much as possible to avoid restriction of tongue mobility. After Obtaining meticulous hemostasis, the tongue defect will be closed in layers.

primary closure for tongue cancer defect

The purpose of this study is to compare the oncological and functional results of the contralateral submental flap with primary closure for reconstruction of tongue squamous cell carcinoma.

Resection of tongue malignancies remains one of most surgical challenges because of its adverse effects on speech articulation, swallowing, and eventual quality of life.

A variety of local flaps such as infrahyoid flap and the Platysma flap, and free flaps like the radial forearm and anterolateral thigh (ALT) flap have been available for reconstruction of tongue. However, all these options have their shortcomings.

When reconstructing particular oral cavity defect the tissue used should be reliable; functional and cosmetically acceptable with minimum donor site morbidity and match the recipient site in terms of color, texture and thickness. The submental island flap (SMI-flap) which has been first introduced by Martin et al in 1990, meets all these requirements and due to its optimal location, ease of harvest, and favorable arc of rotation, the SMI-flap has gained acceptance as a simple, reliable and convenient to repair defects of tongue and oral cavity cancer.

The oncological safety of submental flap in oral cancer patient still debate, this is due to its proximity to the main nodal basins of levels 1A and 1B and the possibility of transfer of occult metastatic lymph node to the recipient site during reconstruction.

in addition some authors has not been recommended submental flap for cases with clinically or radiologically established nodal disease as it might compromise the oncological resection and continuity of neck dissection and so alternative options should be considered. The contralateral submental island flap (CSMI-flap) is believed to offer such alternate option for patient with contralateral negative node.

our a priori-hypothesis is that utilization of the CSMI-flap is not related to an altered prognosis in tongue squamous cell carcinoma patients. In order to test this hypothesis, we will compare the oncological outcome of group of patients receive CSMI-flap with the results of another group of patients not receive CSMI-flap and close tongue defect by primary closure, which is another well-established concept of management tongue cancer defect.

Because the two interventions used in this trial are clearly different and easly recognized by the participants and investigators, neither investigators nor Participants can be blinded.

The statistician will be blinded.
