Most cases occur in scuba divers and fliers, and is easily diagnosed when presented to physicians immediately after exposure. On the other hand, the problem may remain undiagnosed when the history fails to relate the symptoms to exposure to environmental pressure changes or if the focus is on other etiologies. Grades Weissman defined three grades of sinus barotraumas according to symptomatology. * Grade I includes cases with mild transient sinus discomfort without changes visible on X-ray. * Grade II is characterized by severe pain for up to 24 h, with some mucosal thickening on X-ray. * Patients with grade III have severe pain lasting for more than 24 h and X-ray shows severe mucosal thickening or opacification of the affected sinus; epistaxis or subsequent sinusitis may be observed.
