Secondary Reconstruction of Head and Neck Cancer Defects-Principles in its Practice.

Secondary reconstruction is requested by patients who have completed their head and neck cancer treatment. The reason for the request for reconstruction may be to improve the functional deficits, achieve aesthetic refinements or most commonly both. The article looks at various issues related to reconstruction in the secondary setting and suggesting the ways to approaching patients requesting secondary reconstruction. While considering secondary reconstruction, various factors need to be considered. These include issues related to the disease, the treatment received as well as the patient's comorbid conditions. Aggressive disease and multiple recurrences should deter from undertaking complex reconstructions. Lack of tissue pliability resulting in a woody neck due to radiation makes dissection difficult and wound healing poor. The reconstructive requirements include release of contractures inside the mouth, reconstruction of the missing jaws, replacement of the missing volume of the tongue and correction of the incompetent angle of mouth. Goals of reconstruction should be prioritized by the surgical team. Free soft tissue or bone containing flaps would be provided ideal tissue to meet the reconstructive requirements in secondary reconstruction. However, several impediments could exist for their safe use. Release of contractures and provision of adequate soft tissue should be given priority and must be addressed before bony reconstruction is contemplated. Bony reconstruction of both mandible and maxilla is possible, with the former being more difficult to deliver good results due to the associated soft tissue fibrosis. Virtual surgical planning with the aid of Stereo lithographic models and planning software will improve the quality of bony reconstruction. Detailed counseling sessions involving patient and the family are essential before embarking on secondary reconstruction as the patient expectations and the surgical outcome may not be easy to match. However excellent improvement in function and appearance will be possible in many patients with appropriate reconstructive procedure.
