title: Oropharyngeal reconstruction: current state of the art.
abstract: Oropharyngeal reconstruction represents one of the greatest challenges in the surgical rehabilitation of patients with head and neck cancer. This article reviews several reconstruction methods, starting with the primary closure and healing by secondary intention all the way to the complex sensate microvascular flap reconstructions. Small defects such as tonsillar, small tongue base, and partial palatal defects may be closed primarily or left to granulate. This is assuming that there is no communication with the neck or bone exposure. Local flaps such as the palatal island, submental, and buccal mucosal flaps are used to close small to moderate-sized defects. Split-thickness skin grafts are also appropriate for small to moderate-sized defects. Larger defects such as total palatal, more than 50% of the tongue base, and composite tongue base/palatal/pharyngeal defects may be closed with regional myocutaneous pedicled flaps such as the pectoralis major, lower trapezius, or latissimus dorsi pedicled flaps. Microvascular tissue transfer is an excellent alternative for closure of moderate to large-sized defects. Free tissue transfer includes the radial forearm and the lateral arm free flaps. Both of these can have a sensory component. Free jejunal flaps are used for total or subtotal hypopharyngeal defects. Free gastro-omental flaps may be used for oropharyngeal and hypopharyngeal reconstruction as well. For defects involving bone, fibular flaps are an excellent option and can provide sensation. The scapular free flap may be used as well and offers the advantage of having two skin paddles (scapular and parascapular) for internal and external lining. Following a reconstructive ladder is extremely important in ensuring good function and, hence, improved quality of life.
