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.
ABSTRACT
The diagnosis and treatment of the lacrimal passage obstruction with lacrimal endoscope was investigated and its subsidiary surgical procedures were evaluated. Ninety-three patients (109 eyes) with lacrimal passage obstruction, including presaccal canalicular obstruction (PSCO) and na-solacrimal duct obstruction (NLDO), were examined under a lacrimal endoscope, and the obstruc-tions were treated with laser or micro-drill. All patients were followed up after the operation for 3-6 months. The difference between the laser and the micro-drill treatment was observed. During the pe-riod of follow-up, the curative rate was 82.57%. The healing rate in PSCO group and NLDO was 80.36% and 84.91% respectively (P>0.05). After treatment with the laser, the healing rate was 93.33% in the PSCO group and 66.67% in the NLDO group respectively (P<0.05). After treatment with the micro-drill, the healing rate in PSCO and NLDO groups was 65.39% and 94.28% respec-tively (P<0.01). The lacrimal passage obstruction can be observed and treated directly through the lacrimal endoscope. Choosing different surgical procedures in operation according to the locations of the obstruction is helpful to improve the effectiveness.
