title: Fat grafting is a feasible technique for the sequelae of head and neck cancer treatment.
abstract: OBJECTIVE
  The fatty tissue regenerative properties have already been used to correct secondary scars (mastectomy, HIV lipodystrophy), resulting in improved elasticity and tissue quality. However there has been limited experience in treating the sequela of head and neck cancer treatment using fat tissue grafting. The objective of this study was to perform a preliminary evaluation of the injection of autologous fat (IAF) technique, for the sequelae treatment in head and neck cancer patients.
  
  
  METHODS
  We performed a prospective preliminary study to confirm the viability of the IAF in 12 patients previously treated with surgery and radiotherapy in our hospital.
  
  
  RESULTS
  Clinically, the fat grafts provided aesthetic and functional improvement in 83% and 92% of patients, respectively, according to the scoring system. No complications were found during surgery and all the patients were discharged the same day.
  
  
  CONCLUSIONS
  We suggest that the IAF could be a viable alternative to more invasive surgical procedures in the head and neck region, in order to obtain both functional and aesthetic improvement.
