Efficacy of octyl-2-cyanoacrylate in type I tympanoplasty

To evaluate the safety and efficacy of octyl-2-cyanoacrylate for type I tympanoplasty. This study involved 23 patients (14 females and 9 males) with chronic otitis media who underwent type I tympanoplasty. During surgery, the temporal fascia is placed underlying the eardrum remnant, and octyl-2-cyanoacrylate was dropped over the temporal fascia. The mean air-bone gap (ABG) at the 4 frequencies (500, 1000, 2000, and 4000) was calculated for each patient before and after surgery. These data were compared by Student t test. The mean follow-up was 10 months (range, 6-12 mo). Successful tympanic membrane grafting occurred in 21 patients (91.3%). Graft failure was seen in 2 patients. The mean preoperative ABG of the 23 patients was 19.3 (SD, 5.7) dB, and the postoperative ABG improved to a mean value of 8.2 (SD, 5.9) dB (P ≤ 0.0001). Octyl-2-cyanoacrylate is effective and safe in using as a compound on temporalis muscle fascia in type I tympanoplasty and can be used more widely in tympanoplasty.
