Objectve In order to prvent postoperative complications, evaluation of postoperative ultrasonic inspection on effusion in surgical region after head and neck surgeries was performed.Methods 34 surgical cases with head and neck cancer were divided into effusion group and non- effusion group based on the results of postoperative ultrasonography. Rates of effusion was studied according to the following potential predictors: surgery performed, tumor stage, patients with diabetes mellitus, duration of surgery, neck dissection,muscle flap repairation, duration of postoperative drainage and the time of postoperative ultrasonograhy . In addition, the effusion influences on postoperative hospital stay and pharyngeal fistula are also discussed.Results There was statistically significance in the incidence of postoperative effusion beteeen the surgeries of pharyngeal cavity opening and laryngeal cavity opening(P<0.05). No statistical significancant influecnces on effucion were found concerning the factors of tumor stage, neck dissection , myocutaneous flap repairation, duration of sugery, duration of postoperative drainage and the time of postoperative ultrasonograhy(P>0.05). Diabetes acted as a significant factor in postoperative effusion and pharyngeal fistula (P<0.05). Postoperative effusion significantly increased the rate of pharyngeal fistula and the duration of postoperative hospital stay.Conclusion Patients with a pharyngeal cavity opening surgery showed a higher incidence of postoperative effusion than the others who had surgeries of laryngeal cavity; Patients with diabetes may have a higher opportunity of postoperative effusion and pharyngeal fistula; Patients who were foud effusion in the postoperative region by ultrasonograhy after removing drainage tube will have a longer hospital stay as well as higher risk of pharyngeal fistula. Color ultrasonography used in the postoperative region of head and neck is a safe and effective examination in diagnosis and management of postoperative effusion. |
