This is the first case of sinus barotrauma secondary to an inflammatory maxillary sinus polyp, confirmed by histologic diagnosis, reported in the aeromedical literature.The nasal passage and paranasal sinuses (collectively sinonasal) plays host to a number of diseases and conditions, which can be collectively termed sinonasal disease.

The patient was advise tdo return home and rest. Overpressurization in the sphenoid sinus occasionally compresses the optic nerve, causing decreased vision or blindness ( 3, 4 General references Barotrauma is tissue injury caused by a pressure-related change in. Endoscopic sinus surgery was performed completely. A diagnosis of maxillary sinus barotrauma with neurapraxia of the infraorbital nerve and/o its intra-sinu r s branche wass made. Maxillary sinus overpressurization can compress the maxillary branch of the trigeminal nerve, causing hyperesthesia over the cheek. Examination of nasal cavity and computed tomography scan of sinuses suggested left maxillary sinus barotrauma. 1, 2 Barotrauma of the paranasal sinuses is a risk factor for anyone exposed to ambient pressure changes. The patient had complete resolution and clearance to fly after an uneventful 4-wk convalescence and altitude chamber flight. Sinus X-ray views revealed moderate mucosal conges-tion of both maxillary and frontal sinuses. Barosinusitis is characterized by inflammation of one or more of the paranasal sinuses, with inflammation being caused by a pressure gradient, almost always negative, between the sinus cavity and the surrounding ambient environment.

It causes severe pain, requiring strong analgesics during and after decompression. Obstruction can, therefore, lead to problems with sinus pressure equilibration with atmospheric pressure, and can lead to barosinusitis. Download Citation Maxillary Sinus Barotrauma in a Silent Maxillary Sinus Syndrome Scenario: Case Report Barosinusitis is defined as an entity where damage to a paranasal sinus occurs secondary. Multiple etiologies have all led to mucosal inflammation and thickening with potential obstruction of the sinus osteomeatal complex, especially during the barometric changes of flight. Sinus barotrauma, secondary to mucosal disturbances, is a common finding within the aviation community. sinus barotrauma occur in the frontal sinuses with pain localized over the frontal area.
