Sinus Barotrauma
what sinus is most commonly affected?
Frontal sinus is most commonly affected
*Just like the ear, sinus barotrauma usually occurs on descent
Sinus Barotrauma
Aeromedical disposition for isolated episode
Isolated episodes of sinus barotrauma are NCD (you can fly once symptoms resolve)
*imaging immediately after an episode is not indicated and may not be required in mild cases. If severe, CT w/o contrast can be obtained 2 weeks after episode
Sinus Barotrauma
Aeromedical disposition for recurrent episodes
Treatment?
Patients with recurrent sinus barotrauma should be placed in a down status and request an ENT consult
Sinus surgery (FESS) is a highly effective treatment for recurrent sinus barotrauma
Conditions leading to reoccurring vertigo carry significan safety-of-flight concerns and are CD

BPPV
S/S:
Dispo
Tx
BPPV
- vertigo in BPPV is positional and caused by pitch-plane movements
- Diagnose with Dix-Halpike maneuver
- remember: there will be a delayed onset of nystagmu
- Tx: Epley or other repositioning maneuvers
- DO NOT PRESCRIBE VESTIBULAR SUPPRESSANTS OR ANY MEDICATIONS FOR BPPV
- DISPO:
- CD with waiver required after successful treatment and patient is asymptomatic for at least 4 weeks (depending on the platform and occupation)
Vestibular neuronitis/labrinthitis
S/S
Usually preceded by URI
Vertigo (severe and lasting hours to days) followed by days toweeks of instability and/or imbalance
Labryhthitis involves vertigo and sensorineural hearing loss (no hearing loss in vestibular neuronitis)
Vestibular neuronitis/labrinthitis
Treatment
Dispo
- Treatment
- treat acutely with oral steroids, vestibular suppressants, and antiemetics
- once recovering, avoid vestibular suppressants to allow for faster central compensation
- Dispo:
- CD and waiver are required if not recovered by 4 weeks
What is the most common cause of vertigo?
Vestibular migraine is (probably) the most common cause of vertigo
What is the aeromedical disposition for vestibular migraines
migraines are CD for all flight classes and service groups
What is meniere’s triad?
Meniere’s triad
recurrent vertigo episodes (lasting minutes to hours)
low-frequency sensorineural hearing loss and tinnitus
fullness
Meniere’s Disease
Management
Dispo
Meniere’s Disease
- management
- URGENT ENT and audiology eval
- exactly the same as labyrinthitis or sudden sensorineural loss
