Gál Břetislav, MD, Ph.D. Pekařská 53, Brno , 656 91 Disorder of the ear congenital anomalies inflammations tumors injuries Microotia III. St. Microotia Treacher-Collins syndrome Most affected individuals have underdeveloped facial bones, particularly the cheek bones, and a very small jaw and chin (micrognathia). Conductive Hearing loss in about half of all affected individuals; - defects or by underdevelopment of the external meatus. People with Treacher Collins syndrome usually have normal intelligence. Apendices praeauriculares Apostasis auriculae Blunt attachment angle Herpes zoster oticus (part of Ramsey-Hunt syndrome) acute finding – after 3 days – after 10 days Perichondritis Chronic polychondritis – alergy- cauliflower ear Spinocellular cancer of auricle Othematoma (fresh injury; after 14 days; after some months) Earwax (Cerumen) Foreign body in external meatus - insect Insect, ventilation tube Foreign body in external meatus bead, piece of wood, blood Exostosis in ext. meatus right Erysipelas bullosa auricullae Inflammation of external meatus Furunculus of external meatus Middle ear cavity inflammations According to course, extension, localization Acute – Catarrhus tubotympanalis acutus – Otitis media acuta Chronic – Non suppurative – otitis media chronica secretorica (OMA, celistvý bubínek) – suppurative (permanent perforation) § Otitis media chronica simplex – mostly mesotympanal § Otitis media chronica with polyps, granulations § Otitis media chronica cum ostitide § Otitis media chronica cum cholesteatomate Catarrhus tubotympanalis acutus Symptoms – feeling of fulness in the ear, pressure, hearing disorder. Retracted ear drum, without perforation, tympanometry curve type C. Th: treatment of upper airway inflammations, aeration od middle ear cavity. retracted ear drum Otitis media acuta Infection - way: epipharyngeal, hematogenic, injury. Pneumococcus, haemophilus infl., Moraxella catarrhalis 1. Stage of tubal occlusion – Blood vessel injection, without reflex, mild pressure, hearing disorder 2. Stage of exudation – Gradual bulging of ear drum, pain, fever, nausea, vomiting 3. Stage of suppuration – ear drum without contours, spontaneous perforation 4.

Otoscopy: pars tensa - central perforation, changed middle ear epithelium, polyps, granulations. Central perforation in antero-inferior quadrant Otitis media chronica suppurativa mesotympanalis Treatment § Treatment of upper airway inflammation, improvement of nasal patency tube function. § Local antibiotics , combination with s corticosteroids . § Polyps and granulations removed surgically , ev. in 3-6 months myringoplasty, ev. Reconstruction of ossicle chain. Prognosis Favorite Complications rare Otitis media chronica epitympanalis § Localization in epitympanal cavity; § Frequently connected with cholesteatoma and osteitides § Possible destruction of ossicular chain, bone of middle ear cavity, Theory of genesis 1. Tube Dysfunction – pocket in Schrapnellově membrane – perforation –cholesteatoma 2. Direct growth of epithelium through defect of ear drum into middle ear 3. Embryogenetic theory – congenital cholesteatoma Symptoms: smelly discharge, hearing disorder, occasionally ear pain, ev. paresis n.VII Otoscopy – perforation in pars flaccida Therapy – surgery with removal of cholesteatoma Polyp in otitis med. chronica, Defect of epitympanl space after removal of cholesteatoma Subtotal perforation of ear drum Complications of middle ear inflammation In antibiotic era rare § Otologic – mastoiditis, petrositis, paresis , n. VII labyrinthitis § Intracranial – abscessus epiduralis, subduralis, meningitis, brain and cerebellar abscess Mastoiditis Inflamation of processus mastoideus temporal bone. Osseal septums are melted (radiologic diagnosis). § Usually complication of middle earcavity inflam. § Rarely hematologic spread or injury Mastoiditis - forms § acute (in 2–4 weeks after mediootitis, 50 % of all mastoiditis); § subacute § latents Mastoiditis - symptoms § Acute mastoiditis: fever, palpating pain, retroauricular infiltration, apostasis auriculae or antalgic head position, purulent discharge from ear chanal , worsening of hypacusis, tinnitus, worsening of general condition § Subacute and latent mastoiditis (mild symptoms): some pain – feeling of pressure, hypacusis Bezolds absces in child Mastoiditis Diagnosis: § History of disease § Otoscopy – posterior wall drop, signs of inflam.

The externally worn audio processor detects sounds and sends them to the internal implant, which is placed just under the skin behind the ear. The sound is encoded in processor, electric signal is sended into internal implant and through flexible electrode, which is introduced into the cochlea stimulates directly neurons of auditory nerve. Electric signals are led into the brain, where they are interpreted as sound. Vibrant soundbridge – middle ear implant hearing system. Vibroplasty The externally worn audio processor receive and detects sounds and convert them into electrical signals, which are sent to the internal implant. Electrical signals are led into FMT, which change it into mechanical vibration and directly stimulate ossicles or round window niche or different vibratory structures.
