The pressure difference causes the mucosal lining of the sinuses to become swollen and submucosal bleeding follows with further difficulties ventilating the sinus, especially if the orifices are involved. Ultimately fluid or blood will fill the space. In most cases of sinus barotrauma, localized pain to the frontal area is the predominant symptom.
Nasal endoscopy and clinical symptoms are also used to make a positive diagnosis. [28] A tissue sample for histology and cultures can also be collected and tested.
