Spots Global Cancer Trial Database for Oncological Outcome of Contralateral Submental Artery Island Flap Versus Primary Closure in Tongue Squamous Cell Carcinoma

Study Description

Brief Summary: 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.

Detailed Description: 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.
