Stapes gusher is a rare and usually unexpected complication of stapes surgery. This complication will inevitably be encountered during stapes surgery in all affected males with the X-linked, progressive mixed deafness syndrome. The opportunity of studying eight affected males in a large Dutch family with audiometry, vestibulometry, and polytomography was used to identify specific features. Awareness of these features will assist the otologist in recognizing new cases preoperatively.
