Dermal Regeneration Template: Reconstruction in Oral Cancer Defects

BACKGROUND: Post ablative oral mucosal defect resulting from the removal of tumors can be treated with various techniques. PURPOSE: In this paper, we are showing what, in our experience, are the advantages and disadvantages given using biosynthetic skin substitutes when dealing with this kind of lesions. MATERIALS AND METHODS: Patients included in the sample came to our attention with both neoplastic lesions (11 subjects) and important scar retraction after previous oncologic surgery (1 subject). All patients underwent trans-oral resection surgery following the same surgical protocol and post ablative oral mucosal defect were treated using the dermal regeneration template. The surgical defect location, size, and time of removal of the silicone layer varied from one subject to the other. RESULTS: Most patients showed good healing with reduced scarring and adequate remucosalisation of the defect. The main complications were shown in a palatal lesion treated with concomitant osteal resection, which developed an oroantral fistula at follow up, and tongue lesions which showed some scarring. CONCLUSIONS: Given our experience, we would advise using dermal substitutes when reconstructing oral defects only after a cautious evaluation of the area of the lesion, the gap size, the possible adherence of the membrane to the gap, and the presence of tissue supporting the overlying membrane.
