title: [The clinical observation of the repair of pharyngeal mucosa and neck skin defects with acellular dermal matrix].
abstract: OBJECTIVE
  To evaluate the clinical effect of acellular dermal matrix (ADM) on the repair of different tissue defects in pharyngeal and laryngeal cancer.
  
  
  METHODS
  Twenty-three cases of pharyngeal and laryngeal cancer were analyzed retrospectively, including 16 patients with pharyngeal cancer, and 7 patients with laryngeal cancer. After surgery, the patients appeared two types of tissue defects respectively: hypopharynx tissue defect and neck skin tissue defect. These defects were repaired with ADM, and the clinical effects were observed.
  
  
  RESULTS
  Sixteen cases of hypopharynx tissue defect and 7 cases of neck skin tissue defect were repaired with ADM. One case in hypopharynx tissue defect group and 2 cases in neck skin tissue defect group undergone pharyngeal fistula postoperatively.
  
  
  CONCLUSIONS
  The repair of tissue defects in pharyngeal and laryngeal cancer with ADM had some advantages, such as good histocompatibility, low immune rejection, wide material sources and simple method. There were some differences in clinical effects between hypopharynx cavity defect and neck skin tissue defects, so the emphasis of the need to pay attention to is different in the clinical.
