Since impairment of cochlear blood flow is one of the factors implicated in the pathophysiology of sudden deafness, we measured cochlear blood flow in nine patients suspected of having perilymphatic fistulas. All but one patient had sudden sensorineural hearing loss. The exceptional case had experienced rotatory vertigo immediately after nose-blowing. In the eight patients with sudden deafness,...

OBJECTIVE To describe the incidence and main clinical characteristics of barotrauma during open lung ventilation (OLV). DESIGN A retrospective, observational, descriptive study was made of 100 patients with acute respiratory failure and bilateral pulmonary infiltrates. INTERVENTIONS 1) A lung recruitment maneuver (LRM) with fixed ventilation pressure and progressive positive end-expiratory ...

Cecal perforation due to barotrauma is an increasingly recognized complication of colonoscopy when using room air for insufflation. CO2 is increasingly being utilized for insufflation due to more rapid absorption compared to ambient air and results in reduced post-procedural pain and flatulence. Use of CO2 is thought to protect against barotrauma injury, and use of CO2 during endoscopy has not ...

Pneumocephalus is defined as an intracranial gas collection which can be localized in the epidural, subdural, subarachnoid, intraventricular or intraparenchymal spaces. Pneumocephalus has numerous causes, including barotrauma, neoplasms, and spinal anesthesia. However, the majority of pneumocephalus cases are traumatic or iatrogenic in nature. A review of 295 patients with pneumocephalus by Mar...

OBJECTIVE We report three cases of recurrent, unilateral facial palsy associated with air travel. METHOD The three cases are presented, along with a brief literature review concerning barotrauma and its association with air travel and facial palsy. RESULTS All three patients experienced unilateral facial paralysis during air travel, accompanied by additional symptoms which varied between ca...

The Valsalva manoeuvre is commonly used in diving to equalise middle ear pressures during descent. A forceful expiration with the nostrils and mouth held shut results in an increased nasopharyngeal pressure and opening of the Eustachian tubes. The correctly performed manoeuvre is easily taught, effective and usually without complications. When performed incorrectly, prolonged periods of raised ...

Overfished species of rockfish, Sebastes spp., from the Northeast Pacific experience high bycatch mortality because of 'barotrauma', a condition induced from the rapid change in pressure during capture. Field experiments show that it may be possible for rockfish to recover from barotrauma if quickly recompressed; however, no work has followed the physiological recovery of rockfish after recompr...

Changes in ambient pressure, for example, during flying, diving, or hyperbaric oxygen therapy, can lead to barotrauma. Although it may seem that this issue was neglected in dental education and research in recent decades, familiarity with and understanding of these facts may be of importance for dental practitioners. We report the case of a patient who experienced barotrauma involving dislodgem...
