![]() ![]() Air Force flyers were grounded for a total of 1,182 days with the primary diagnosis of aerosinusitis. Nosebleed is a common event with diving and can be caused by negative pressure within the mask or from pressure change after ascent. ![]() Thus the essential environmental requirement for the development of sinus barotrauma is frequently present, and cases of aerosinusitis are common. Sinus Barotrauma This most often involves the frontal or maxillary sinuses and the pressure differential usually causes the lining of the sinuses to become swollen and bleeding can ensue. 1 However, in certain military aircraft, particularly high-performance jet fighters, various maneuversĬreate marked and rapid changes in barometric pressure despite cabin pressurization. Severe aerosinusitis rarely occurs during flight in civilian aircraft, because the fluctuation of barometric pressure is usually well controlled by cabin pressurization and gradual ascent and descent. We report a case of a diver who suffered an episode of maxillary sinus barotrauma that presented with decreased sensation over the cutaneous distribution of. This lesion filled the sinus, occluded the nasofrontal duct, and required surgical intervention. However, in the case to be presented here, barotrauma produced a frontal sinus hematoma which subsequently enlarged to form a hemorrhagic cyst. ![]() Ordinarily this disease responds quickly to conservative treatment as outlined in standard otolaryngologic texts. Because visual recovery depends on prompt diagnosis and proper therapy, physicians like otolaryngologists, ophthalmologists and neurologists need to closely collaborate.īarotrauma diving mucocele sphenoid sinus vision loss.Aerosinusitis continues to occur with significant frequency. The damage is due to compressive/ expansive forces and shear, leading to overstretching of tissues. Risk factors for sinus barotrauma when underwater diving or flying include any etiology that would narrow or obstruct the natural sinus ostia. We show that injuries can develop from both negative and positive pressures in the sinuses. Barotrauma is physical tissue damage caused by an unrelieved pressure differential between a surrounding gas or fluid and an unvented body cavity (e.g., sinuses, lungs), or across a tissue plane. Diving and aviation studies show that decompression associated with descent and increased gravity cause sinus barotrauma twice as often as in cases related to ascent, compression, and reverse squeeze. Divers and physicians should have in mind that occasional headache during or after diving sometimes signals serious neurological disorders like vision loss. on anatomical and pathophysiological features. ![]() After searching the literature (Medline) and other sources (Internet), we present some cases of sphenoid sinus barotrauma, because these injuries may be underreported and misdiagnosed due to the lack of awareness and knowledge. This is the conse- quence of a pressure difference between the nasal fos. Thus, barotrauma could lead to serious neurologic disorders, including blindness. Sinus barotrauma is the disorder arising from the pressure variations of the ambient. Vital structures, as internal carotid artery and optic nerve, adjoin the sphenoid sinus. The sphenoid sinuses are rarely involved. About 50% of scuba divers have suffered from barotrauma of the ears and about one-third from barotrauma of paranasal sinuses. ![]()
