Observe the curative effect of n-Butyl cyanoacrylate injection in treating laryngopharynx hemangioma / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To evaluate the clinical effectiveness of injection n-Butyl cyanoacrylate (NBCA) in treating laryngopharynx hemangioma.@*METHOD@#Thirty cases of laryngopharynx hemangioma who received NBCA injection were obtained from our department 1998-2007. Twenty-five cases had tracheotomy under General anesthesia, and NBCA was injected into hemangioma by direct laryngoscopy. NBCA was mixed with iodide, and the concentration was 25.00% to 33.33%, NBCA dosage was 0.5 ml to 2.0 ml. There were 5 cases whose hemangioma confined to oropharynx didn't have tracheotomy, and they were injected straightly with the speculum oris. We observed the shedding of hemangioma in different time.@*RESULT@#Hemangioma with diameter less than 1 cm, shedded in about 1 month. However, hemangioma with diameter more than 4 cm, shedded in a period more than 3.5 month. No recurrence was observed in the follow up of 3 months to seven years.@*CONCLUSION@#Avoiding dissection of neck and repetitious operation, NBCA injection could be a safe, simple and effective therapy for laryngopharynx hemangioma.
