The wound infections caused at upper aerodigestive cancer surgeries may give unsatisfactory result, even when prophylactic antiobiotics were used. The conditions of the patients and the progression of the tumor may be the major affecting factors. In different tumor stage, the extent of the wound infectin caused by the affecting factors is different. We have found there are statistical correlations between ”with or without tracheotomy”, ”tumor stage”, ”tumor size”, ”lymph node metastasis”, ”flap reconstruction”, ”complicated surgical procedure”, ”operation time” and ”blood loss”, and postoperative wound infection in the total patient group. But in comparison again under each tumor stage, only ”with or without tracheotomy”, ”operation time” and ”blood loss” have correlation with wound infections. These reveal that the latter 3 factors may have important relationship to wound infections. Prominent statistic relationship is found in comparing the wound infections between the tumors of the oral cavith and laryngeal or pharyngeal area. The queer changes about infection rates of tracheotomy time in different tumor stage will be discussed.
