Résumé
Objective To investigate the clinical application effect of independently designed subcutaneous tunnel in endo‐scopic thyroid operation .Methods A total of 480 cases of endoscopic thyroid operation were completed in our department from February 2005 to December 2014 ,in which 315 cases adopted the independently designed subcutaneous tunnel for separating the subcutaneous tissues in anterior thoracic region and the other 165 cases used the puncture stick for separating and constructing the subcutaneous tunnel .Results Using independently designed subcutaneous tunnel for constructing the subcutaneous tunnel in the anterior thoracic region had statistical difference in the operative time and intraoperative bleeding amount compared with the punc‐ture stick(P<0 .05) ,and the difference of postoperative complications between the two groups was statistically signifficant (P<0 .05) .Conclusion Adopting the independently designed subcutaneous tunnel for constructing subcutaneous tunnel has the advan‐tages of short time consuming ,less bleeding and fewer complications .The level and size of the constructed subcutaneous tunnel are easy to grasp ,so which is more convenient for endoscopic thyroid operation .
