Reports from Kaiser Permanente Advance Knowledge in Exostoses (Complication Rates In Osteotome and Drill Techniques In External Auditory Canal Exostoses: a Systematic Review and Meta-analysis).

A systematic review and meta-analysis conducted by researchers at Kaiser Permanente in Oakland, California, compared complication rates in external auditory canal exostoses treated with drill versus osteotome canalplasty. The study included 15 studies with a total of 1399 patients and found that the osteotome technique was associated with a lower rate of sensorineural hearing loss and stenosis, but a higher rate of tympanic membrane perforation compared to the drill technique. The research concluded that additional randomized studies are needed to assess clinical efficacy in treating EAC exostectomy complications. [Extracted from the article]
