For vertical saccades upward or downward, eyes always move to the right, which is contralateral to the side of the stroke (on the left).
Horner's syndrome (Faught and Oh, 1985), but as the lesion in Wallenberg syndrome is usually below the auditory connections, Horners due to Wallenbergs are not generally associated with abnormal ABR. PICA is the most common site of occlusion from propagating thrombus or embolism caused by injury to the third section of the vertebral artery, and Wallenberg's syndrome is the most common stroke caused by chiropractic manipulation (Caplan, 1986).
If you believe your child has a hearing loss, please come to our office in Chico to meet with one of our Audiologists. OTITIS MEDIA Otitis media (OM) may be defined as inflammation of the middle ear due to any cause. OTITIS MEDIA -- DIAGNOSIS Children with acute otitis media frequently present with sudden onset of fever, ear pain, and fussiness. OTITIS MEDIA -- COMPLICATIONS Complications of acute otitis media were common in the pre- antibiotic era.
HEARING LOSS Conductive hearing loss Cerumen impactions Swelling of the external auditory canal Tympanic membrane perforation Middle ear fluid Ossicular chain abnormalities Sensorineural hearing loss Injury to hair cells in the cochlea or neural elements innervating the hair cells. HEARING LOSS -- AUDIOMETRY Hearing threshold levels are determined between 250 and 8000 Hertz (Hz) for pure tones and measured in decibels (dB).
HEARING LOSS -- AUDIOMETRY A conductive hearing loss in the left ear due to otitis media with effusion. HEARING LOSS -- AUDIOMETRY This audiogram suggests noise exposure that may be encountered occasionally in younger individuals who have been exposed to hazardous or “toxic” noise.
HEARING LOSS -- TYMPANOGRAM Tympanometry is commonly used to evaluate the tympanic membrane (TM) and middle ear status.
Three tympanograms demonstrating change in compliance of the middle ear (vertical axis) with changes in ear canal pressure. OTITIS EXTERNA Otitis externa (OE) is an inflammation or infection of the external auditory canal (EAC), the auricle, or both This condition can be found in all age groups. OTITIS EXTERNA -- CONSIDERATIONS Ramsay Hunt syndrome, more accurately known as herpes zoster oticus, is caused by varicella-zoster virus (VZV) infection. OTITIS EXTERNA -- TREATMENT Commonly used topical eardrops are acetic acid drops (which decrease pH), antibacterial drops, and antifungal preparations. DIZZINESS Patients frequently present with a complaint of “dizziness,” including symptoms such as disequilibrium, syncope, lightheadedness, ataxia, and vertigo.
DIZZINESS – VESTIBULAR TESTING Vestibular testing can be performed to help determine whether the problem exists within the vestibular (balance) portion of the inner ear. DIZZINESS – VESTIBULAR TESTING There are four main parts to ENG testing Calibration test, which measures rapid eye movements Tracking test, which evaluates the ability of the eyes to track a moving target Positional test, which measures responses due to head movements Caloric test, which measures responses to warm and cold water introduced to the ear canal. BENIGN PAROXYSMAL POSITIONAL VERTIGO (BPPV) One of the most common causes of vertigo is benign paroxysmal positional vertigo (BPPV). BENIGN PAROXYSMAL POSITIONAL VERTIGO (BPPV) BPPV can usually be successfully treated with a canolith reposition maneuver (Epley or Semont maneuver) in the office setting. Bedside maneuver for the treatment of a patient with benign paroxysmal positional vertigo (BPPV) affecting the right posterior semicircular canal. LABRYNTHITIS -- TREATMENT Treatment is symptomatic Vestibular suppressant medications (meclizine) Antiemetics Short, tapering course of oral steroids It may take several weeks for symptoms to completely resolve Residual vestibulopathy that persists for months or even years is not uncommon, and is best managed with vestibular rehabilitation.
CT-angiography with 3D reconstruction has gotten good enough in recent years to be helpful too. Dilated petrosquamosal sinus, mastoid emissary vein, and external jugular vein: A rare cause of pulsatile tinnitus, vertigo, and sensorineural hearing loss.
Around 10% of population in the USA has tinnitus and 60% of them have no diagnosis, despite extensive workup done for them. Anatomy of the mastoid emissary vein and venous system of the posterior neck region: Neurosurgical implications. The cranial venous system in man in reference to development, adult configuration, and relation to the arteries. Morphology of the temporal canal and postglenoid foramen with reference to the size of the jugular foramen in man and selected species of animals. The loss can range from mild, one that causes difficulty hearing hushed tones such as a whisper, to moderately severe, where the child can still hear loud speech, to a total loss resulting in deafness.
A conductive loss is the most common and is associated with conditions in the external or middle ear that block the transmission of sound. Timely hearing testing, diagnosis and treatment will provide the best course of action ensuring the highest quality lifetime experiences for your child.
Due to: persistent noise exposure, age-related (presbycusis), genetic factors, and infectious or postinflammatory processes. The 0-dB level is “normalized” to young, healthy adults and doesn’t mean there is absence of detectable sound.

Note that bone conduction thresholds are normal in both ears, but air conduction on the left is 30 dB poorer than that measured on the right. Note that low-tone thresholds are relatively normal, with a drop in thresholds at higher frequencies. This test assesses the mobility of the TM and its response to pressure changes in the external auditory canal. Type A is normal, with the greatest compliance at the point where the pressure in the ear canal is equal to that of atmospheric pressure (peak is at 0).
If the condition does not respond to treatment as expected, an otolaryngologist should evaluate the patient.
It is characterized by facial nerve paralysis and sensorineural hearing loss, with bullous myringitis and a vesicular eruption of the concha of the pinna and the external auditory canal (EAC). True vertigo (an illusion of motion) is primarily associated with the balance organs of the inner ear. BPPV is caused by sediment, such as calcium carbonate crystals, that have become free floating within the inner ear.
Dislodged otoliths repositioned into the vestibule is about 80 percent effective in eliminating symptoms of BPPV.
The presumed position of the debris within the labyrinth during the maneuver is shown in panels A–D. It is thought to be caused by inflammation, secondary to a viral infection, of the vestibular portion of the eighth cranial nerve or of the inner ear balance organs (vestibular labyrinth). We know it is not due to the head being tilted, because in that case, the eyes would not always go the same direction. These conditions can include ear infection, fluid in the ear, impacted ear wax, a perforated ear drum, a foreign object in the canal or birth defects that alter the canal. Most often, this type of loss is caused by congenital infections, the use of ototoxic drugs (antibiotics), premature birth with a very low birth weight and some of the resulting treatments or a number of other medical conditions. There are two common variants: (1) acute otitis media (AOM) and (2) otitis media with effusion (OME). There is decreased movement of the eardrum on pneumatic otoscopy (insufflation of air into the ear canal). Mastoiditis -- Patients with acute mastoiditis present with fever, ear pain, and a protruding auricle. Some patients hear 0 dB, but reaching the threshold of hearing usually requires louder test signals.
This is a consequence of the normal aging process and may vary widely from patient to patient.
Type B demonstrates very poor compliance at any frequency, suggestive of a tympanic membrane (TM) immobilized by fluid in the middle ear or a TM perforation (no peak).
Skull base osteomyelitis occurs most often in patients who are diabetic or immunocompromised. Rotatory chair testing is the “gold standard” for diagnosing bilateral vestibular weakness. Turning the head quickly or into a certain position, causes this free- floating material to move the endolymph in the inner ear, stimulating the vestibular division of the eighth cranial nerve.
Because the eyes can go either way, ipsi or contra, the localizing significance of pulsion is not teriffic.
It can be associated with conditions like drug, allergy, or systemic illness, while objective one can be heard by both patients, and examina, which most of the time is related to a vascular cause.
It  impacts not only the sound experience of a life yet to be lived to the fullest, but also creates a barrier to a child’s number one job, learning.
Although there is no cure for this type of hearing loss, in most cases children can often be helped with hearing aids.
Ears Otitis media Hearing loss Otitis externa Vertigo Nose Sinusitis Allergic rhinitis Epistaxis Throat Strep.
Common bacteria that cause acute OM in children are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Meningitis With increasing antibiotic resistance, especially Streptococcus pneumoniae, these complications may again become more common.
Type C represents a tympanogram in which the compliance of the membrane is greatest at a point where the pressure in the canal is 200 mm of water below that of atmospheric pressure (peak shifted to the left). The patient is slowly spun in a rotating chair and dizzinessis is measured with optokinetic testing and a fixation test. The Dix-Hallpike test is performed with the patient’s head rotated 45? toward the right ear, and the neck slightly extended with the chin pointed slightly upward. The patient will usually awaken with room-spinning vertigo that will gradually become less intense over 24–48 hours.

Fortunately, many causes of hearing loss are treatable, and it is often possible to return the sounds of childhood to a young life. In healthy children older than two years of age who present with less severe symptoms, observation for 48 hours may be considered.
This suggests inefficient eustachian tube function with persistent negative pressure in the middle ear.
The diagnosis is strongly suggested by a history of diabetes mellitus, severe otalgia, cranial neuropathies, and characteristic EAC findings. Moving platform posturography is a method of quantifying balance, but should not be used alone to diagnose vestibular disorders. Medical therapy with vestibular suppressants is ineffective because the episodes of vertigo are so fleeting, and should be discouraged.
During the audiogram, independent thresholds are determined for each ear for both air conduction (conductive hearing) and bone conduction (sensorineural hearing).
It is most useful in quantifying balance improvement (or worsening) following treatment for a particular problem, and can help identify the functional dizzy patient. Once the vertigo and the nystagmus provoked by the Dix-Hallpike test cease, the patient’s head is rotated about the rostral-caudal body axis until the left ear is down (panel B).
ECOG is not really a test of the vestibular system, but is a useful test of hearing in the evaluation of Meniere’s disease. It gets relieved occasionally after he play sports and take shower and then starts again after few hours.Vertiginous attacks for two years (lasting for 20-60 minutes), true vertigo, it was related to head movement when he turned his head to either sides, but more toward the right side, and associated with nausea, vomiting, sweating and imbalance, no change of tinnitus, no aural fullness or hearing loss during the attacks, no cardiac or neurological symptoms, no headache.
The test is a variant of brainstem audio-evoked response and, if possible, should be performed during active Meniere’s attacks. Three attacks of vertigo during the first year and five attacks during the last year have been observed. The last one is the most severe one lasting for seven hours, which was two months ago and has been admitted in the hospital and was associated with hearing loss in the right ear.
With the head kept turned toward the left shoulder, the patient is rought into the seated position (panel D). Once the patient is upright, the head is tilted so that the chin is pointed slightly downward.
Now, since the last vertiginous attack two months ago, no more attacks of vertigo have been observed, but still continues to have tinnitus and mild hearing loss, occasional imbalance mainly on the right side. He avoids looking quickly to right or left, instead he moves the head slowly to each side because when he turns the head quickly, he experiences vertigo.
There are many causes for subjective tinnitus like labrynthitis, otits media, ototoxicity, and otosclerosis. In around 70% of the patients with this type of tinnitus, the diagnosis will be achieved by imaging studies and treatment plan can be started accordingly.
Sometimes, turbulents of blood flow can cause noise (tinnitus) which may be decreased by applying pressure to area of responsible vein.
Mastoid emissary vein connect suboccipital venous plexus to sigmoid sinus through mastoid foramen. Then, continuation of temporal vein to external jugular vein which was also dilated in this patient with no abberant distal obstruction, the diameter of external jugular vein was 11.7 mm [Figure 4]. This explains the reason when applying pressure over the area of deep temporal vein or external jugular vein causes decrease in tinnitus pitch by 50% according to the patient and does not disappear completely due to the presence of mastoid emissary vein dilatation. Petro-squamosalsinus was described before CT scan based on temporal bone disecssions, [4],[11] but now-a-days, CT scan give us an excellent tool to help in the diagnosis of vascular anomaly in temporal bone which is much easier and faster with detailed description of the structure. We can't explain the presence of vertigo in this patient although it was reported before, but tinnitus presentation is first time to be reported in association with petro-squamosalsinus. The combination of presence of petro-squamosalsinus, dilated mastoid vein, dilated external jugular vein, tinnitus, vertigo, and sensorineural hearing loss is first described in our patient which was not described before in the literature.In general, presence of any vascular anomaly in the temporal bone raise the hazard of surgical procedure in such patients as severe bleeding. Also, we asked him to avoid turning his head quickly to any side in order to minimize the attacks of vertigo. With the follow-up of every six months, the patient has informed us that he has been following our instructions well and that he is felling much better now with only one mild attack of vertigo over the last six months, and tinnitus is still there, but it is not annoying him anymore. Patients with petro-squamosalsinus (PSS), dilated mastoid emissay vein, and external jugular vein may be presented with vertigo, tinnitus, and hearing loss.
