Definitions of sudden sensorineural hearing loss (SSHL) vary widely, depending on severity, time course, audiometric criteria, and frequency spectrum of the loss.
Only about 10 to 15 percent of people with SSHL will ever know what actually caused their loss. Sudden sensorineural hearing loss most often occurs a week or so after a person has experienced a viral or bacterial infection, such as a head cold or the flu. Estimates of the annual incidence of sudden sensorineural hearing loss range from five to 20 cases per 100,000 people. Introducao: O schwanoma vestibular, tumor benigno e com origem na celula de Schwann do VIII nervo craniano, pode apresentar-se clinicamente como surdez subita, cujo extenso diagnostico diferencial pode oferecer dificuldades a investigacao clinica. Relato de caso: Os autores relatam a melhora do quadro audiologico de um paciente com surdez subita submetido a tratamento clinico, sugerindo uma etiologia nao cirurgica ou idiopatica para a disacusia.
Conclusao: A recuperacao auditiva apos tratamento farmacologico num paciente com diagnostico de surdez subita nao exclui o schwanoma vestibular como possivel agente etiologico.
Introduction: The vestibular schwannoma, a benign tumor that originates from the Schwann cells in the eighth cranial nerve, may presents clinically as sudden hearing loss (SHL), whose broad differential diagnosis can make difficult a clinical investigation. Case report: The authors report an unusual case of a patient with SHL whose empiric treatment with systemic corticosteroid and vasodilator caused complete improvement of audiologic state, suggesting a clinical or idiopathic etiology. Conclusion: Auditory recovery after conservative management of SHL does not exclude vestibular schwannoma. INTRODUCAOA surdez subita (SS) usualmente e definida como uma perda auditiva do tipo sensorio-neural de inicio subito ou rapidamente progressivo em minutos, horas ou alguns dias. In order to understand the various treatment options, it is important to understand some of the anatomy and physiology of the ear. The ear is divided into three main parts, the outer ear, the middle ear, and the inner ear.A The outer ear consists of the auricle and ear canal and eardrum.
Tympanic membrane perforation: A large hole in the ear drum, like a hole in a pocket, allows some sound energy to escape and be wasted.
Otosclerosis: Stiffening of the stirrups bone, like arthritis restricts transmission of sound.
Acoustic neuroma: This and other brain tumors can cause pressure on the hearing nerve and thus disrupt transmission of sound. Sudden onset sensorineural hearing loss: This is a type of nerve hearing loss that occurs rapidly over the course of hours to days because of damage to the inner ear hair cells. On the other hand, sensorineural hearing loss is usuallyA irreversibleA -- with only a few exceptions.
Pantothenate deficiency symptoms are thought to be uncommon because of widespread distribution in all foodstuffs. Vitamin E is an antioxidant that protects cell membranes and other fat-soluble compounds from oxidative damage by free radicals. Vitamin E exists in eight chemical forms (alpha-, beta-, gamma-, and delta-tocopherol and alpha-, beta-, gamma-, and delta-tocotrienol) that have varying levels of biological activity. Common conditions associated with vitamin A deficiency - Hormone balance, Immunidex, Insomnia, night blindness. When a person takes prescription drugs or over the counter medication chances are that they can be affecting their nutrient levels. B vitamins, Vitamin K - short term depletion affects are minimal, but failure to re-inoculate the GI tract with beneficial bacteria (probiotics) often results in dysbiosis which causes gas, bloating, decreases digestion & absorption of nutrients, and also may lead to a variety of other health problems.

Research suggests nutrient depletions from commonly prescribed drugs are actually the cause of many side effects - A recently published review details the enzymatic pathways that various drugs interrupt and how certain drugs deplete very specific nutrients. Study sheds light on how oleic acid improves immunity - By affecting compounds released during an immune response, oleic acid quells inflammation and improves overall immunity. A commonly used criterion to qualify for this diagnosis is a sensorineural hearing loss of greater than 30 dB over three contiguous pure-tone frequencies occurring within a three-day period. When they see their family physician, it is often mistakenly confused with a common middle-ear infection and treated thusly. No single treatment has been shown to be unequivocally effective in treating patients with SSHL. Porem, seguindo-se um satisfatorio grau de suspeicao, a otoneurologia e a radiologia, particularmente a ressonancia magnetica, oferecem uma valiosa semiologia complementar para o diagnostico do schwanoma vestibular.
Uma adequada investigacao otoneurologica e de imagem deve sempre seguir-se a suspeita clinica de surdez subita. However,after suspicion, otoneurology and radiology, in particular the magnetic resonance imaging, offer valuable complementary semiology for vestibular schwannoma diagnosis. An otoneurological and radiological investigation should always be performed in patients presenting sudden hearing loss.
Estima-se que representa 1% de todos os casos de perda auditiva sensorio-neural (1).E consequencia de diferentes desordens, locais ou sistemicas, sendo que o tratamento ideal desta condicao encontra-se no manejo da causa subjacente quando se tem uma etiologia definida.
Oftentimes, it is only when we lose this special gift, that we realize its importance.A In the early days, there was not very much to be done about hearing loss. However, human deficiency symptoms may include fatigue, depression, burning feet, dermatitis, burning or pain of arms and legs, anorexia, nausea, indigestion, irritability, mental depression, fainting, hair loss, increased heart rate, and susceptibility to infection.

Below are some of the possible deficiencies that are correlated with each corresponding drug. Specifically, oleic acid, abundant in olive oil, inhibits the production of several pro-inflammatory substances, such as Interleukin 2 (IL-2), natural killer cells (NK), interferon-gamma (INF-I?) and vascular cell adhesion molecules (VCAM). Depressive symptoms were decreased and there was a dose-dependent reduction in damaging chemicals in the brain that are linked with depression. Rauch, “Idiopathic sudden sensorineural hearing loss,” New England Journal of Medicine, vol.
Fortunately, the vast majority of cases of sudden hearing loss are unilateral, and the prognosis for some recovery of hearing is good. Early treatment for SSHL can save your hearing, so it’s important to see a hearing healthcare professional for immediate evaluation.
However, the anti-inflammatory properties of corticosteroids make them a common treatment option. O schwannoma vestibular (SV), tambem conhecido como neurinoma do acustico, que constitui o termo consagrado ao longo dos anos, e um tumor benigno com origem na celula de Schwann do oitavo nervo craniano.Em cerca de 5 a 10% dos casos o SV manifesta-se clinicamente como SS (2).
These three hearing bones are connected in such a way that using mechanical leverage, they are able to amplify sounds and transmit the vibrations to the inner ear.A The inner ear is completely encased in bone and consists of a cochlea and a labyrinth.
Hearing aids consist of tiny microphones and speakers that boosts the volume of incoming sounds. Alpha-tocopherol has direct effect on the control of inflammation, red and white blood cell production, connective tissue growth and genetic control of cell division.
Retinol is the most biologically active form of vitamin A and is synthesized by pro-vitamin A(beta-carotene). Oleic acid also reduces the amount of arachidonic acid (AA) present in cells, which in turn minimizes pro-inflammatory cytokine production.
Although spontaneous recovery does occur, SSHL is a medical emergency and requires immediate medical evaluation.
Evaluation should include a careful history and physical examination, including diagnostic audiometric testing.
Most people do recover at least some of the hearing lost, but about 15 percent have symptoms that continue to worsen. Before the industrial revolution, crude devices shaped like trumpets were developed to collect and funnel sound into the ear.
For instance, if hair cells at the base of the spiral cochlea grow weak and die, a high frequency nerve hearing loss will occur. There are many types and configurations of hearing aids, each of which has its own advantages and disadvantages. For those patients with resultant permanent hearing loss, hearing technologies such as hearing aids and implantable devices can often help. That represented the birth of the hearing aid.A As technology progressed, it was discovered that there were different types of hearing loss that could be treated in a variety of ways. Problems that cause conductive hearing loss usually reside at the external ear or middle ear.

Destes ultimos, quatro pacientes (23%) recuperaram em algum grau a funcao auditiva antes da exerese cirurgica do tumor, sendo tres casos na ausencia de qualquer tratamento farmacologico e um apos corticoterapia. Inside the cochlea, the vibrations transmitted by the hearing bones move little hair cells. The following are some causes for sensorineural hearing loss.A Presbycusis -- a fancy name for age-related hearing loss. Digital hearing aids can give clearer sounds, however they are usually more expensive.A Wearing hearing aids is much like wearing glasses. To review our experience with intratympanic steroids (ITSs) for the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL), emphasizing the ideal time to perform follow-up audiograms. High-pitched sounds stimulate high-pitched hair cells that are located at the base of the spiral.
Noise induced hearing loss: loud noises enter the cochlea near the base of the spiral and damage these cells first.
These specialized hair cells, in turn, fire off nerve impulses that the brain interprets as high-pitched sounds. Retrospective case review of patients diagnosed with ISSNHL treated with intratympanic methylprednisolone. Desta populacao, 42 casos foram submetidos, inicialmente, a tratamento medicamentoso para a disacusia, sendo que 20 (47,6%) pacientes apresentaram melhora clinica documentada por audiometria. The complexity of features and circuitry within the hearing instruments determines the cost of the device. O exame otorrinolaringologico evidenciou uma otoscopia simples e pneumatica sem anormalidades.
A primeira audiometria (Figura 1) mostrou uma perda auditiva do tipo sensorio-neural moderada a severa em frequencias agudas no ouvido esquerdo, sem anormalidade contralateral e com ausencia de recrutamento.


Feita a suspeita diagnostica de surdez subita com etiologia a ser esclarecida, o paciente foi medicado empiricamente com codergocrina e betametasona, alem de orientado sobre medidas gerais.Concomitantemente, foi solicitado um hemograma completo, coagulograma, VHS(velocidade de hemossendimentacao), testes hematologicos para sifilis e perfil metabolico, alem de vecto-eletronistagmografiia (VENG), audiometria de tronco cerebral e ressonancia magnetica (RM) contrastada do oitavo nervo e fossa posterior. O paciente relatou melhora acentuada da hipoacusia e desaparecimento do zumbido apos 48h de tratamento.
Uma nova audiometria (Figura 2) mostrou normalizacao de todos os limiares auditivos no ouvido previamente comprometido.

Isto se deve provavelmente a elevada definicao da imagem por RM para tecidos moles, capaz de evidenciar tumores com diametro inferior a 1,5 cm, um fator limitante para a imagem por tomografia computadorizada dos ossos temporais utilizada como controle nos estudos anteriores a popularizacao da RM (10).Por esta propriedade, a RM contrastada com gadolinio ou em “Fast Spin Echo”, menos invasiva e com menor custo por dispensar contraste, tornou-se o padrao-ouro para o diagnostico do SV (11).
Transtornos do equilibrio e comprometimento de outros nervos cranianos podem estar presentes, sobretudo em estagios mais avancados da doenca. A prevalencia do SV entre pacientes com SS e desconhecida, mas estima-se que varia de 0,8 a 2,5% (4).
Segundo Schukhnecht (13), mudancas degenerativas no interior do SV podem causar flutuacoes na sintomatologia.
Aquele autor descreve que o edema e a hemorragia intratumoral podem levar, isolados ou conjuntamente, a um aumento subito nas dimensoes do tumor.Analogamente, pode-se especular que eventos expansivos semelhantes concorram na genese de um quadro sintomatico agudo como a surdez subita. O tratamento do SV e essencialmente cirurgico, talvez com raras excecoes que poderiam incluir pacientes com estado geral comprometido por morbidades coexistentes ou senilidade, o que tornaria temerosa uma intervencao cirurgica de grande porte (2).O paciente em estudo foi submetido a exerese cirurgica da tumoracao por via retrolabirintica, realizada sem intercorrencias, e encontra- se atualmente no sexto mes pos-operatorio em acompanhamento ambulatorial.
