Emergency physicians should strongly consider a diagnosis of sinus barotrauma in patients who present with symptoms of sinusitis and a history of recent flight. [ncbi.nlm.nih.gov]

• Dentist

  Regular checkups with your dentist avoid this unnecessary risk of incapacitation. [pilotfriend.com]

  Should I come in and see you guys or go to the dentist? This is an unusual story but similar cases have been reported in the past. The explanation is probably this. [londondivingchamber.co.uk]

• Nausea

  Inflow of cold water to the middle ear may result in vertigo, nausea, and disorientation while submerged. [merckmanuals.com]

  If a migraine develops, the dive should be terminated because of the potential for nausea, emesis and alteration of consciousness. [aafp.org]

• Vomiting

  Vertigo is characterized by a spinning sensation and is usually accompanied by nausea and vomiting, while dizziness is a sensation of loss of balance. [alertdiver.com]

  Inner ear barotrauma often involves rupture of the round or oval window, which causes tinnitus, sensorineural hearing loss, vertigo, nausea, and vomiting. The resulting labyrinthine fistula and perilymph leakage can permanently damage the inner ear. [merckmanuals.com]

• Hypertension

  HAH often awakened the study participants from sleep or occurred upon wakening and was exacerbated by bending, coughing, or sneezing, suggesting the possibility of intracranial (meaning within the cranium or skull) hypertension as a contributing factor [migrainetrust.org]

• Eye Pain

  If you are having eye pain, this is potentially serious (some of the sinuses are right next to the eyes) and you should NOT push through this to dive. [scubaboard.com]

• Tingling

  Referred pain to the maxillary teeth was due to pressure on the posterior superior alveolar branch and paresthesia with numbness and tingling of the lip and cheek was caused from pressure on the infraorbital nerve prior to its emergence through the infraorbital [ncbi.nlm.nih.gov]

  Severe symptoms can include: Numbness and tingling in your arms and legs. Dizziness. Trouble breathing. Staggering or other trouble walking. Trouble seeing. Confusion. Chest pain. Passing out (losing consciousness). [northshore.org]

  The most severe presentation is partial myelopathy referable to the thoracic spinal cord. 10, 15 Patients complain of paresthesias and sensory loss in the trunk and extremities, a tingling or constricting sensation around the thorax, ascending leg weakness [aafp.org]

• Frontal Headache

  Abstract An amateur scuba (Self Contained Underwater Breathing Apparatus) diver experienced an acute frontal headache following a low-depth dive. [ncbi.nlm.nih.gov]

  A mass lesion in the frontal sinus, consistent with submucosal hematoma secondary to barotrauma, was thought to be the cause of the headache. [ajnr.org]

  Look for: Suspicion of intracranial spread - severe frontal headache, frontal swelling, symptoms or signs of meningitis or focal neurological signs. Suspicion of spread to the orbit - see separate article Orbital and Preseptal Cellulitis. [patient.info]

• Agitation

  Hearing loss (temporary) Bleeding from the ear (rare) Sinus Barotrauma Sinus pressure and/or pain Nasal bleeding Headaches Tooth pain Pulmonary Barotrauma Symptoms from an air embolism to the brain include reactions similar to a stroke: Headache Confusion Agitation [knowyourdisease.com]

With more severe sinus barotrauma, the patient notes the following possibly incapacitating signs and symptoms: Sudden onset of typically severe and sharp pain and pressure - Pain is typically in the forehead, midface, or retro-orbital area Epistaxis Workup [emedicine.medscape.com]

Before treatment, divers who required surgery reported significantly more symptoms than divers who were treated conservatively. Post treatment there were no significant differences between the medical and surgical group. [ncbi.nlm.nih.gov]

Prognosis All but the acute invasive form carry a good prognosis once the diagnosis is made and treatment completed. Fulminant fungal sinusitis is associated with a 50% mortality rate, even with aggressive surgical and medical treatment. [patient.info]

Outlook (Prognosis) Barotrauma is usually noncancerous ( benign ) and responds to self-care. Hearing loss is almost always temporary. When to Contact a Medical Professional Try home care measures first. [mountsinai.org]

Epidemiology Frequency United States Prevalence is approximately 3-4 episodes per 100,000 exposures in a generally healthy population. [emedicine.medscape.com]

Epidemiology Although this is less common than acute sinusitis, it remains a reasonably common entity in itself, accounting for about 25 cases per 10,000 person-years in an average UK GP practice [ 2 ]. [patient.info]
