2017 
: Objective:To investigate the efficacy and safety of treating laryngeal hemangioma by injecting bleomycin with self-made laryngeal microinjector under the suspension laryngoscope and operating microscope.Method:Thirteen patients with hemangioma of larynx(diameters of tumors range from 1.2-3.8 cm) were admitted and treated by injecting bleomycin with a modified laryngeal micro-injector under the suspension laryngoscope and operating microscope from January 2012 to September 2016. According to the tumor size, 4.5-7.5 mg bleomycin was injected and the patients received treatment every four weeks until there were no evident tumor residues. Result:Four of the 13 patients were cured after the first injection, 6 were cured after the second injection, and 3 cured after the third injection. All cases were followed up without recurrence. Conclusion:Bleomycin injection with a modified laryngeal micro injector under the suspension laryngoscope and operating microscope is proved to be a effective measure with the advantage of precise, minimal- invasive, and efficient therapeutic effect in treatment of laryngeal hemangioma.
