About This Presentation

Description : Check out this medical PowerPoint presentation titled "Non-purulent ear diseases".

This medical PowerPoint presentation is about non-purulent ear diseases, conditions that affect the ear without the presence of pus or discharge. Some common non-purulent ear diseases include:

Otitis media with effusion (OME): This is a condition where fluid builds up in the middle ear without any signs of infection. It can cause hearing loss, ear pain, and balance problems.
Tinnitus: This is a condition where you hear ringing, buzzing, or other sounds in your ears. It can be caused by exposure to loud noise, age-related hearing loss, or other underlying conditions.
Menieres disease: This is a disorder of the inner ear that can cause vertigo, ringing in the ears, and hearing loss. It is believed to be caused by a buildup of fluid in the inner ear.
Otosclerosis: This is a condition where the bones in the middle ear become fixed and cannot vibrate properly, leading to hearing loss.
Eustachian tube dysfunction: This is a condition where the tube that connects the middle ear to the back of the throat becomes blocked, causing pain, pressure, and hearing loss.
Acoustic neuroma: This is a rare type of tumor that can grow on the nerve that connects the ear to the brain. It can cause hearing loss, tinnitus, and balance problems.

It is important to consult a healthcare professional if you experience any symptoms related to non-purulent ear diseases.

Sensorineural hearing loss (SHL) a form of hearing loss in which one of the sections of the sound-receiving Department of the auditory analyzer is affected, starting from the sensory cells of the inner ear and ending with the cortical representation in the temporal lobe of the cerebral cortex.
Slide 4-

Social and medical significance of the problem of sensorineural hearing loss Prevalence: 13 million people worldwide have significant hearing changes. By 2020, the population with socially significant hearing loss will increase by 30%: who forecast A significant percentage of patients are in the age groups of high social and professional activity The problem of childhood. Congenital hearing loss is, on average, 1-2: 1000 newborns The problem of older age groups Early manifestation of presbyacoussis in residents of industrialized areas due to chronic noise injury (sound pressure level in the metro-90-100 dB)

Cochlear implantation A cochlear implant is a medical device that allows partial or complete restoration of hearing in some patients with severe or severe SHL www.myshared.ru/slide/1360262/
Slide 20-

Cochlear implant: how it works The function of the cochlear implant –stimulation by electrical impulses of the auditory nerve fibers in the cochlea The cochlear implant consists ofexternal (wearable) and internal (implantable) parts. The wearable part contains: Microphone Microprocessor to convert the sound into electrical impulses Transmitter The implantable part contains: Receiver Signal decoder A system of electrodes that are implanted in the cochlea and located on the basilar membrane, directly in contact with the auditory nerves
Slide 21-

Tinnitus: classification objective (vibratory) - audible to an outside observer and can be registered using auscultation and other instrumental methods of examination of the patient (5%) Reasons: Pathology of temporomandibular joints Myoclonus of the middle ear muscles, soft palate Dehiscence of the auditory tube
Slide 22-

Tinnitus: classification Subjective (non-vibratory) - occurs in the absence of a real sound source and does not lend itself to evaluation from the outside (95%) Reasons: Metabolic (cerebral atherosclerosis, hepatitis, diabetes mellitus, hypoglycemia, Hypo - and hyperthyroidism) Diseases of the external, middle, inner ear (sulfur plug, exostosis of the external auditory canal, external otitis, otitis media, otosclerosis, nst, acoustic and barotrauma, Meniere's disease, hunt syndrome) "perception of silence" - a manifestation of endogenous somatic sounds, usually masked by environmental sounds, in a healthy person who is in a soundproof room

Meniere's Disease t is characterized by variability of hypotheses and clinical manifestations of peripheral cochleovestibular disorders attacks of dizziness, accompanied by nausea, vomiting, balance disorderprogressive unilateral hearing loss (80-90%) noise in the affected ear As an independent nosological form identified by Prosper Menier (1861)
Slide 27-

Meniere's disease: clinical classification In shape: typical (classical) - a triad of signs described by Meniere: noise in the ear and hearing loss, balance disorders, vegetative disordersatypical -manifestations of individual signs of the triadcochlear vestibular Lermuaye syndrome (hearing loss and painful ear noise, dizziness attacks, during which the cochlear symptoms regress) Adrift: attack (angioedema) acute period Remission status meniericus
Slide 28-

Meniere's disease: etiology proximate cause – endolymphatic hydropspredominance of the tone of the parasympathetic part of the autonomic nervous system, which occurs as a result of vegetative-vascular dystoniapredisposing factor: poor circulation in the system of vascularization of the labyrinth metabolic disorders, in particular water-salt dysfunction of the endocrine system development of perivascular fibrosis
Slide 29-

The mechanism of development of hydrops of the labyrinth hyperproduction of endolymph reduction of endolymph resorption violation of membrane permeability
Slide 30-

Theories of Meniere's disease development Anatomical (hypoplasia or obliteration of the vestibular water supply, sclerotic changes of the temporal bone pyramid in the immediate vicinity of the endolymphatic SAC and the vestibular water supply on the affected side, reduction in the size of the endolymphatic SAC) Genetic (autosomal dominant type of inheritance of this pathology) Immunological (detection of immune complexes in the endolymphatic SAC in patients with MD) Vascular (MD connection with migraine) Allergic (the frequency of allergic reactions in patients with MD is higher than in the General population) Metabolic (potassium retention in the endolymphatic space causes potassium intoxication of hair cells and vestibular neuroepithelium, resulting in hearing loss and dizziness)
Slide 31-

“Obvious” Meniere's disease: definition AAO–HNS (American Academy of Otolaryngology and head and neck Surgery, 1995) ≥2 spontaneous vertigo attacks lasting ≥20 min. hearing loss confirmed by audiological studies in at least one case ear noise and / or feeling of congestion in the causal ear other reasons are excluded
Slide 32-

Stages of Meniere's disease reversible-attacks of cochleo-vestibular-vegetative disorders, hydrops is detected only in the period immediately preceding the attack, on the tonal audiogram-the presence of a conductive componentpronounced clinical manifestations - the presence of symptoms of Meniere's disease, intra-Labirint pressure is constantly increased, hearing fluctuation, on the tonal audiogram-the predominance of the sensorineural componentthe final one is the presence of a symptom complex of Meniere's disease, progressive hearing loss, the bone-air gap disappears on the tonal audiogram, the curves acquire a descending configuration
Slide 33-

Diagnosis of Meniere's disease Computer stabilometry Video oculography Audiometry Vestibular myogenic evoked potentials (MEP) (no peaks P13, N23-graph as a straight line) Electrocochleography. Transtimpanal electrocochleography (violation of the ratio of values of amplitudes SP (summation potential) /PD (action potential): p>0.3) Dehydration tests Duplex scanning of brachiocephalic vessels Variational heart rate monitoring Magnetic resonance imaging of the brain and cervical spine
Slide 34-

Electrocochleography otoacustica.com.br/eletrococleografia.html If there is a hydropse in the inner ear, the following signs are detected The increase in the amplitude of the negative wave summation potential (SP), a preceding action potential (AP), with a corresponding increase in the amplitude of the summation potential and action potential more 0,42.2. Shift of the latent period of the action potential during alternate stimulation with clicks with the initial phase of thickening and dilution by more than 0.2 MS.3. The change in the amplitude of the summation potential in the study of tonal parcels at a frequency of 1000-2000 Hz.Clinical recommendations
