We hereby present a rare cause of disequilibrium and SSCDS, diagnosed by clinical presentations, audiological tests and imaging. [ FULL TEXT ] [ PDF ]* [amhsjournal.org]

Case presentation A 45-year-old Caucasian patient presented with a 5-year isolated history of noise induced vertigo and a history of head trauma 12 years ago. [jmedicalcasereports.biomedcentral.com]

A woman in her 30s, the daughter of the aforementioned patient, presented with dizziness and headaches in 2011. The daughter’s symptoms started during pregnancy (1 year prior to presentation). [jamanetwork.com]

Battista is an excellent presenter...clear, concise. Highly recommend. by Danielle on June 6, 2017 Dr. Battista is an excellent presenter. [audiologyonline.com]

We present a protocol to establish the diagnosis of a similar condition, especially those presenting atypically. [ejo.eg.net]

• Disability

  Because she was not incapacitating symptoms, our goal of the treatment was to control symptoms, reduce functional disability and improve her quality of life. [ejao.org]

  Disabling symptoms persist in those cases where membranous labyrinth was damaged previously and in cases with bilateral dehiscence [30,31]. [medcraveonline.com]

  Sound or pressure can trigger abnormal activation of the balance canals in the ear, which in turn leads to a wide range of distressing and disabling symptoms. [eurordis.org]

  Abstract Hyperacusis can be a prominent and disabling symptom of superior semicircular canal dehiscence associated with autophony and the Tullio phenomenon. [ncbi.nlm.nih.gov]

  She put her full-time publishing career on hold to raise her children, the youngest of whom was born severely disabled as a result of a rare chromosome disorder, and her own life has been seriously affected by the balance disorder SCDS. [hearinghealthmatters.org]

• Falling

  Patient 2 A 32 year old man presented with visual instability and a tendency to fall forward and to the left provoked by loud sounds such as the telephone ringing in his left ear. [doi.org]

  With the benefit of hindsight, I think the first hole (on the right side) may have been caused by a dramatic headfirst fall from a bicycle in my teenage years. I have recently published my whole experience with SCDS and related symptoms in a memoir. [hearinghealthmatters.org]

  SSCD is not a life-threatening disorder as long as it does not result in a fall, motor vehicle accident or some other trauma from poor balance. Consequently, the decision to do any treatment is elective and not mandatory. [rarediseases.org]

  Typical settings for VEMPS include either low frequency tone bursts or clicks at 5 Hz positive polarity, and tones of 500 Hz positive polarity with rise/fall times of 1ms and 2 msec plateau. [canadianaudiologist.ca]

• Pain

  Head Pain and Tegmen Defects: I have been diagnosed with SCDS, but also experience stabbing pains in my head when I cough, sneeze, or clear my throat, bend over. In general, SCDS should not cause pain. [hopkinsmedicine.org]

  During the descent at the end of a flight coming in to Amsterdam, there was a rapid change of pressure and I felt a brutally sharp pain in my left ear. [hearinghealthmatters.org]

  I came out in a worse state, with terrible vertigo and pain," says Philippa. After 18 exhausting months she went to see Dr. Gerard Gianoli in Louisiana. [eurordis.org]

• Hearing Problem

  Superior Canal Dehiscence Symptoms Most symptoms of SCDS are either vestibular (balance-related) problems or auditory (hearing) problems. [share.upmc.com]

• Vertigo

  Case Report A 51-year old female patient presented with intermittent vertigo and left-side aural fullness for one month after traffic accident, especially left sided head trauma. Loud sound evoked sensation of vertigo and disequilibrium. [ejao.org]

  Historical note and terminology The Tullio phenomenon is sound-induced vertigo, nystagmus, or both. [medlink.com]

  The result was postoperative reduction in vertigo and closure of the air-bone gap on the audiogram (Table 1). The stapedius reflexes were present, with no vertigo. The postoperative CT verified reconstruction of the bone ( Figure 3 b). Figure 3. [em-consulte.com]

  Case presentation A 45-year-old Caucasian patient presented with a 5-year isolated history of noise induced vertigo and a history of head trauma 12 years ago. [jmedicalcasereports.biomedcentral.com]

  However, the most common symptoms are vertigo/dizziness elicited by pressure altering activity, Tullio’s phenomenon (sound-induced vertigo), fullness/pressure in the ear and autophony. [rarediseases.org]

• Headache

  Headache and migraine are also often mentioned by patients showing other symptoms of SCDS due to the body overcompensating for poor hearing in the affected ear by tensing up nearby parts of the face, head, and neck and using them as almost a secondary [en.wikipedia.org]

  […] stationary objects) Autophony (hearing one's voice or self-generated sounds like breathing and blinking louder than normal) Sensitivity to loud sounds Fullness/pressure in the ears Although it may not be directly related, it is not uncommon to also have a headache [my.clevelandclinic.org]

  "The headaches were becoming severe, the nausea persistent, my vision was often blurred, and it was extremely uncomfortable to raise my voice, sing or eat crunchy foods. [eurordis.org]

  Autophony (hearing internal body sounds more loudly, like creaking joints, pulse, and breathing) Low-frequency conductive hearing loss Increased sensitivity to bone-conducted sounds Feeling of fullness in the ear Other symptoms of superior canal dehiscence Headache [share.upmc.com]

• Confusion

  Individuals with SSCD may also have an associated conductive hearing loss, which at times may be confused with otosclerosis or other middle ear hearing disorders. The diagnosis is made with a high resolution CT scan of the temporal bone. [stlouisear.com]

  Several of the symptoms typical to SCDS (e.g. vertigo and Tullio) may also be present singly or as part of Ménière's disease, sometimes causing the one illness to be confused with the other. [en.wikipedia.org]

  Additional reformations in the planes of Stenver and Pöschl do not change the radiologic diagnosis and may be reserved for equivocal or confusing cases. © RSNA, 2006 References 1 Minor LB. Superior canal dehiscence syndrome. [pubs.rsna.org]

  The same sensations gradually extended to other environments and fluctuated wildly, which added further confusion. This continued into my forties. [eurordis.org]

  The unusual presentation of Case 1 with a history of bilateral SNHL with total recovery in one ear and a low frequency conductive hearing loss may be confused with cochlear hydrops, just in the vast majority of cases reported in the literature. [scitechnol.com]

• Episodic Vertigo

  Results and Conclusions Symptoms of superior semicircular canal dehiscence (SSCD) include autophony, inner ear conductive hearing loss, Hennebert sign, and sound-induced episodic vertigo and disequilibrium (Tullio phenomenon), among others. [doi.org]

• Seizure

  Middle fossa craniotomy resurfacing also has a slightly higher risk of seizure than the transmastoid approach because the temporal lobe needs to be retracted. [neurosurgery.ucla.edu]

  Usually plugging is performed for both the anterior and posterior limbs of the canal. 27 The risks of this kind of approach include the small but real risks of intracranial violation, such as a CSF leak, infection and meningitis, and a small risk of seizure [canadianaudiologist.ca]

  […] latter of which developed in one of two patients described by Brantberg et al who underwent transmastoid superior canal occlusion. 2, 24 Middle cranial fossa resurfacing does require retraction of the temporal lobe and carries a slightly higher risk of seizure [ncbi.nlm.nih.gov]

Treatment for SSCD can only be determined after a comprehensive medical examination of an otologist and a full audiological workup. A specialized CT scan of the ear is needed to accurately diagnose the condition. [californiaearinstitute.com]

Preoperative Workup The diagnosis of SCD is made radiographically, therefore all patients should undergo fine cut temporal bone computed tomography (CT) imaging. [csurgeries.com]

Computed tomography-based workup of conductive hearing loss with normal middle ear: don’t forget superior semicircular canal dehiscence Int Tinnitus J 2008 ; 14 : 53-56 [6] Branstetter B.F., Harrigal C., Escott E.J., Hirsch B.E. [em-consulte.com]

It is very important during the workup of SCD to look for other diseases that can cause similar symptoms. The most common one fitting that bill is migraine, which can also co-occur with SCD. [hopkinsmedicine.org]

The minor complications are hematoma, cellulitis, tinnitus. 5, 6) Medical treatment is also considered for treatment, even though no medical treatment has been proven fully effective for SSCD. [ejao.org]

In the cases with bilateral dehiscence, if symptoms continue after surgical treatment, it is proposed the same treatment for the other ear. This is the situation of the fourth case that is pending of surgical treatment in the left ear. [medcraveonline.com]

What Are the Treatment Options for Superior Semicircular Canal Dehiscence? For people with only mild symptoms of SSCD, treatment may be as simple as learning techniques to avoid triggers and manage dizziness. [dariuskohanmd.com]

The nurse reads about acute chest syndrome, including risk factors, signs and symptoms, potential complications, laboratory tests, treatment goals and interventions. [health.ebsco.com]

This article will review our strategy and discuss the advantages and disadvantages of the different surgical treatments used for patients with severe symptoms from superior canal dehiscence. [ncbi.nlm.nih.gov]

Treatment and prognosis Surgical procedures are performed through a middle cranial fossa approach. Plugging or resurfacing the superior semicircular canal has been documented to resolve or improve the symptoms 4. [radiopaedia.org]

Prognosis is generally good, but depends on the treatment employed. Complications from surgery can cause incomplete resolution of hearing loss or balance disturbances and, in some patients, symptoms increase in severity after surgery. [health.ebsco.com]

What is the long-term prognosis if I choose NOT to have MF surgery? Sadly, your story is not uncommon! [hopkinsmedicine.org]

Importance The etiology of superior canal dehiscence (SCD) involving the arcuate eminence is not completely understood, but genetic factors may play a role. [jamanetwork.com]

Recent findings Canal dehiscence involving the superior, lateral, and posterior semicircular canal can have different etiologies, including developmental abnormality, congenital defect, chronic otitis media with cholesteatoma, and high-riding jugular [doi.org]

The etiology is under continuous investigation. [scitechnol.com]

Identifying the etiology is important for purposes of treatment, for if the etiology can be identified, research toward medical management may become feasible. [frontiersin.org]

The etiology of SCD is unknown. Carey et al. [6] suggest that dehiscence arises from a defect in postnatal development. Nadgir et al. [1] study showed that superior SCD is more commonly an acquired rather than congenital or developmental condition. [jscimedcentral.com]

Epidemiology Frequency United States The true incidence of persons with symptomatic SCDS is currently unknown. [emedicine.medscape.com]

[…] canal dehiscence (SSCD) is a defect of the skull base that is gaining increasing recognition among neurosurgeons. 1, 2, 5 It is described as a pathological aperture commonly at the level of the arcuate eminence of the petrous temporal bone. 2 The exact epidemiology [thejns.org]

This video case report demonstrates Hennebert's sign associated with SSCD syndrome and discusses its pathophysiological basis. ISSN: 0023-852X, 1531-4995 PMID: 22252740 [deepblue.lib.umich.edu]

Concerning the pathophysiology of this condition, we hypothesized that the increased volume of inner ear liquid can modify the micromechanical function of the cochlea and the labyrinthine hydrodynamics. [ncbi.nlm.nih.gov]

Overview The author explains the clinical presentation, pathophysiology, diagnostic work-up, and management of superior semicircular canal dehiscence syndrome. [medlink.com]

Pathophysiology The cochleovestibular system has 2 functional windows. The oval window, which houses the footplate of the stapes, allows sound to enter the inner ear (vestibule) and to be carried via hydroacoustic waves through the perilymph. [emedicine.medscape.com]

Pathophysiology: Superior Semicircular Canal Dehiscence Syndrome is characterized by thinning or loss of bone that covers the SSC and which separates it from of the cranial cavity. [medcraveonline.com]

If you are affected by vertigo, dizziness or other balance issues, schedule an appointment with your physician or our office to determine the underlying cause, discuss treatment options, and, in some cases, prevent future problems such as hearing loss [centerforbetterhearing.com]

Resurfacing of the dehiscent canal also prevents chronic stimulation from the pulsating temporal lobe. Transmastoid Approach The surgical technique begins with a post auricular incision, as it usually performed for a mastoidectomy. [ncbi.nlm.nih.gov]
