Treatment of chronic otitis externa by KTP/532 laser

Abstract

The traditional meatoplasty operations performed for chronic otitis externa, which has entered the ‘fibrotic’ phase, are often unsatisfactory because the results in terms of canal patency, hearing gain and patient satisfaction are variable. Although the use of laser in chronic ear surgery is well recognized, it has not been previously reported as a meatoplasty technique. Ten KTP laser meatoplasty operations were performed on eight patients with chronic otitis externa. This pilot study shows the technique to be effective, fast and with a high patient satisfaction rate in the short-term (mean follow-up period 9.3 months). The average increase in hearing thresholds was 24 dB HL. Significant patient benefit was obtained in at least six out of eight patients using the Belfast rule of thumb. The technique has many advantages over the traditional meatoplasty operations but the long-term results require evaluation.

Combined meatoplasty and canalplasty for intractable chronic otitis externa: Our experience of twenty cases with audiometric and patient‐reported outcomes

“…There are three other publications in the current literature which address both subjective and objective outcomes after either meatoplasty or canalplasty for chronic otitis externa, however, none adopt a similar surgical method or have comparable patient groups to our study.…”

“…Management involves regular aural toilet combined with topical antibiotic‐steroid application, in addition to avoidance of causative factors. When these methods fail, surgical intervention by means of a meatoplasty or canalplasty can be offered . Meatoplasty is widening of the lateral cartilaginous section of the external auditory meatus, as opposed to canalplasty which eradicates soft tissue or bony obstruction from the external auditory canal .…”

KTP-532-Laser-Assisted Tympanoplasty

“…KTP-laser-assisted metoplasty operations performed for chronic otitis externa, which has entered the 'fibrotic phase', has been shown to have a high patient satisfaction rate in the short term. The average increase in hearing threshold was 24 dB HL [13]. In animal experiments, the patency of KTP-laser-assisted myringotomies was significantly enhanced following preapplication of mitomycin C [14].…”
