About This Presentation

Description : Check out this medical PowerPoint presentation titled "Vertigo” by Dr. Abdulrahman Alsanosi.

This medical PowerPoint presentation is about vertigo, a type of dizziness or a sensation of spinning or movement, even when a person is stationary. It can be caused by problems in the inner ear, such as benign paroxysmal positional vertigo (BPPV), Menieres disease, or vestibular neuritis. Other causes of vertigo may include head injuries, migraines, or certain medications.

The symptoms of vertigo can include feeling lightheaded, unbalanced, or like the room is spinning. Some people may also experience nausea or vomiting, ringing in the ears, or difficulty standing or walking. Treatment for vertigo depends on the underlying cause and may include medication, exercises to improve balance, or surgery in severe cases. It is important to seek medical attention if you experience symptoms of vertigo, as they can interfere with daily activities and may be a sign of a more serious condition.

Slide 1-

Vertigo Dr. Abdulrahman AlsanosiAssociate professor King Saud University Otolaryngology consultant Otologist , Neurotologist &Skull Base Surgeon King Abdulaziz University Hospital / KFMC
Slide 2-

What are the components of balance system ?
Slide 3-

Inner ear (3 semicicular canals and otolith organ ) Cerebellum Vision (VOR) Proprioceptive
Slide 4-

How does balance system work ?
Slide 5-

Physiology Function of vestibular system: Transform of the forces associate with head acceleration and gravity into a biological signals that the brain can use to develop subjective awareness of head position in space (orientation) produce motor reflexes that will maintain posture and ocular stability
Slide 6-

It is not surprisingly that vestibular lesion cause: Imbalance posture and gait imbalance visual distortion (oscillopsia ).
Slide 7-

oscillopsia
Slide 8-

What is vertigo?
Slide 9-

VERTIGO The word "vertigo" comes from the Latin "vertere", to turn + the suffix "-igo", a condition = a condition of turning about). It is an allusion of being moving or the world is moving too.
Slide 10-

What is nystagmus ?
Slide 11-

What are the questions to ask in history ? Onset Frequency Duration Associated auditory symptoms Aggrevating and relieving factors Ear disease or ear surgery Trauma Migraine Ototoxic drug intake
Slide 12-

Differential diagnosis A) peripheral vestibular loss B) central vestibular loss
Slide 13-

What are the causes of peripheral vestibular loss ?
Slide 14-

peripheral vestibular loss Vestibular neuritis Benign paroxysmal positional vertigo ( BPPV) Meneires disease (Endolymphatic hydrop )
Slide 15-

Vestibular neuritis Viral infection of vestibular organ Affect all ages but rare in childern Affected patient presents acutely with spontaneous nystagmous ,vertigo and nausea &vomiting Patient requires only symptomatic treatment It takes 3 weeks to recover from vestibular neuritis
Slide 16-

Vestibualr neuritis
Slide 17-

BPPV( benign paroxysmal positional vertigo )
Slide 18-

BPPV The most common cause of vertigo in patient > 40 years Repeated attacks of vertigo usually of short duration less than a minute . Provoked by certain positions (rolling in beds, looking up ,and head rotations) Not associated with any hearing impairment
Slide 19-

BPPV Diagnosis History Dix-Halpike maneuver

Endolymphatic hydrop (Meneire’s disease) Pathophysiology : Unknown etiology ↑ ↓production of fluid within inner compartment
Slide 24-

vertigo (minutes to hours ) Low frequency fluctuating SNHL Tinnitus and fullness in the ear. In 10 - 20% of cases the disease later involves the opposite ear
Slide 25-

Meneire’s disease Diagnosis -History -PTA
