[Fitness to dive in the otorhinolaryngological field]

In line with the rising number of recreational divers, the otorhinolaryngologist has to deal with growing numbers of diving-associated disorders of the ear, nose and throat (ENT). Nevertheless, the majority of divers present to their ENT doctor for assessment of their fitness to dive. On the basis of long-term follow-up examinations and increasing experience in diving medicine, even divers with a history of ENT problems can be considered fit to dive. Therefore, diving is possible after tympanoplasty, surgery to improve hearing including stapesplasty, after implantation of middle ear amplifiers or cochlear implants, after sinus or scull base surgery and even after canal wall down mastoidectomy, provided that certain requirements are fulfilled. Assessing fitness to dive after inner ear barotrauma as well as after inner ear decompression illness requires meticulous consideration of residual damage and possible underlying conditions like vascular right-to-left shunts. This article is based on the new recommendations of the German Undersea and Hyperbaric Medical Society for the assessment of fitness to dive in the otorhinolaryngological field.
