Childhood vertigo

Definition And Clinical Presentation

Specific dizziness type defined as illusion or sensation of motion.
Dizziness refers to generalized sensation of altered spatial orientation.
Represents uncommon spontaneous complaint in pediatric population.
Younger children manifest dysequilibrium through falling, stumbling, or profound clumsiness.
Older children accurately describe room spinning or turning sensations.
Unidirectional, horizontal, or jerk nystagmus frequently accompanies true vestibular vertigo.

Etiologic Category	Specific Condition	Clinical Characteristics And Pathophysiology
Middle Ear	Otitis media with effusion	Represents most common cause of dizziness in young children. Fluid accumulation alters middle-ear pressure dynamics.
Vestibular	Benign paroxysmal vertigo	Most common cause of true vertigo in pediatric patients. Features short periods of vertigo lasting seconds to minutes with imbalance and nystagmus. Lacks hearing loss or tinnitus.
Neurologic	Basilar or vestibular migraine	Common cause of episodic vertigo. Accompanied by headache in half to two-thirds of cases. Features rotary nystagmus, phonophobia, and photophobia.
Structural	Perilymphatic fistula	Results from barotrauma, deep water diving, severe head trauma, or physical exertion. Characterized by sudden sensorineural hearing loss and vertigo.
Structural	Semicircular canal dehiscence	Superior semicircular canal bone defect creates abnormal inner ear fluid movement.

Develops as complication of acute otitis media, chronic otitis media, mastoiditis, or bacterial meningitis.
Organisms enter labyrinth through internal auditory meatus, endolymphatic duct, perilymphatic duct, or vascular channels.
Presents with sudden rotatory vertigo, profound dysequilibrium, and deep-seated ear pain.
Child exhibits postural imbalance, frequently demonstrating furniture walking and falls toward affected side.
Spontaneous horizontal or rotary nystagmus universally present.
Subjective hearing loss remains unusual in isolated vestibular neuritis.
Acute serous labyrinthitis occurs secondary to middle-ear infection without direct bacterial invasion.
Acute suppurative labyrinthitis involves direct bacterial invasion, frequently via dehiscent horizontal semicircular canal secondary to cholesteatoma.

Expansile keratinaceous mass erodes bony labyrinth.
Creates labyrinthine fistula, presenting with vertigo and sensorineural hearing loss.
Demands urgent surgical intervention.

Cogan syndrome features interstitial keratitis, vertigo, and hearing loss.
Vogt-Koyanagi-Harada syndrome presents with uveomeningitis, vitiligo, vertigo, and hearing loss.
Susac syndrome involves microangiopathy, retinopathy, encephalopathy, and deafness.

Less common in young children, increasing in prevalence with advancing age.
Pathophysiology involves canalithiasis (calcium debris accumulation) within semicircular canals, most frequently posterior canal.
Symptoms triggered strictly by head position changes.

Condition	Specific Management Protocol
Otitis media with effusion	Unsteadiness typically resolves immediately upon fluid clearance or tympanostomy tube placement.
Acute infectious labyrinthitis	Administer appropriate systemic antimicrobial agents for bacterial etiologies. Use antiviral agents for herpes zoster oticus.
Inflammatory labyrinthitis	Oral corticosteroids reduce labyrinthine inflammation and prevent permanent sequelae.
Acute severe vertigo	Short course (maximum three days) of vestibular suppressants like dimenhydrinate one to two milligrams per kilogram alleviates severe nausea.
Vestibular neuritis	Prescribe prednisone. Institute specific vestibular rehabilitative exercises.
Perilymphatic fistula	Requires immediate surgical middle-ear exploration and repair to control vertigo and stabilize hearing loss.
Benign paroxysmal positional vertigo	Perform specific canalith repositioning maneuvers to physically shift debris from canals into utricle.
Cholesteatoma	Perform mastoidectomy to surgically eradicate destructive mass and address labyrinthine fistula.
