[Middle and inner ear barotrauma caused by scubadiving (author's transl)].

On the basis of our own experiences and the current literature, the following guidelines were established for the evaluation of scubadivers: 1. The ENT physical examination must include otoscopy and the valsalva manoeuver. The scubadiver should be able to promptly and symmetrically inflate his middle ear spaces. A central perforation is a relative contraindication, while a marginal ear drum perforation is an absolute contraindication for scubadiving. 2. Recommendations to the diver: Ear pressure equalibration should be performed continuously with increasing and decreasing water depth. Ear plugs should never be used. 3. Management of diving injuries: Barotitis should be treated in a manner similar to acute otitis media. Transient vertigo while ascending (alternobaric vertigo) without nystagmus or hearing impairment needs no further vestibular examination. A middle ear exploration is indicated when there is suspicion of a perilymphatic fistula.
