RESUMO
The oral cavity is a primary site for malignant neoplasms of the head and neck region. Surgery, with or without adjuvant therapy, offers the highest probability of cure by focusing on radical tumour removal and organ function restoration. Reconstructive options are represented by local and free flaps, while small defects can be managed without reconstruction. For medium-sized defects without bone involvement, local flaps can be a good alternative to free flaps in selected patients. The purposes of this article are to analyse the main minimally-invasive reconstructive techniques in oral cancer surgery through a systematic review of the literature and develop a reconstructive algorithm based on the site and size of the defect. We defined minimally-invasive reconstruction as any reconstructive option not involving flap dissection from the neck or other distant areas from the oral cavity. Options considered include: local myo-mucosal or mucosal flaps (based on the facial or buccal arteries, and palatal flap), Bichat's fat pad flap, and nasolabial flap. Use of biological or synthetic materials is also described. In selected patients with small to moderate-sized defects, the possibility of reconstruction with local flaps can be a viable option.
