ObjectiveTo explore the feasibility of functional laryngeal surgery under selfretaining laryngoscope and rigid telescope with video system.Methods160 cases suffering from benign laryngeal tumors were randomly divided into two groups. 80 patients of the study group received minimally invasive surgery under selfretaining laryngoscope and rigid telescope with video system while those of the control group (n=80) received microsurgery under surgical microscope. The operation time, hospital stay, phonation recovery time, surgical effect and complications were compared between the two groups.ResultsStatistical analysis showed that the operation time of the study group (11.38±4.65 min) was significantly shorter than that of the control group (20.72±3.23 min) (P<0.01). The differences of other parameter between the two groups were all statistically insignificant (all P>0.05).ConclusionWith advantages of short operation time and less surgical difficulty, functional laryngeal surgery is feasible under selfretaining laryngoscope and rigid telescope with video system.
