Abstract
Background: Otosclerosis is not an uncommon condition in Telangana. Various methods such as perforator and laser are usedin performing stapedotomy during its surgical management. Stapedotomy performed with slow-speed microdrill technique forotosclerosis, and difficulties encountered during surgery, complications, and auditory gain in the post-operative period wereanalyzed in this study.Aim of the Study: The aim of this study was to use low-speed microdrill technique in stapedotomy and to analyze the difficulties,complications, and audiological evaluation in the post-operative period of 18 months.Materials and Methods: A prospective study of 62 patients undergoing stapedotomy for otosclerosis over a period of 2 yearswas reviewed. Stapedotomy with skeeter microdrill was evaluated using audiometric results (air conduction thresholds, boneconduction thresholds, air-bone gap closure, and pure tone average) and the incidence of complications during post-operativeperiod. Teflon prosthesis was used in all the patients.Observations and Results: Among the 62 patients, there were 37 females (59.67%) and 25 males (40.32%) with a male-tofemale ratio of 1:1.48. The patients belonged to the age group of 25–55 years with a mean age of 32.65 ± 4.15 years.Conclusions: Stapedotomy performed with microdrill technique for otosclerosis was a safe surgical technique to perforate thestapes footplate. The microdrill (skeeter) has low noise intensity and low torque. For duration of a few seconds, it seems to bea safe tool in creating a perforation in the footplate of the stapes, without causing acoustic trauma.
