This entity is clinically seen as ME infection associated with non healing perforation(TYPES) of TMSlide 3: Etiology 1/socioeconomic group 2/Genetics: Race,mastoid air cell. 3/Previous:AOM,OME. 4/InfectiveSlide 4: 5/URTI viral, sinusitis 6/ Allergy. hay fever. sensitivity to antibiotic ear drops. 7/ Eustachian tube malfunction.Slide 5: Classification of CSOM . 1/ Tubotympanic 2/ AtticoantralSlide 6: Tubotympanic: Disease of anterior part of ME and associated with non healing central perforationSlide 7: Pathology : localised to ME mucosa. Active, quiescent or inactive 1/perforation of TM, central and non healing. 2/Middle ear mucosa: edematous or inactiveSlide 8: 3/Aural polyp 4/ Tympanosclerosis 5/ adhesionsSlide 9: Bacteriology : Aerobes: Ps aeroginosa,Proteus Anaerobes: BacteroidsSlide 10: Clinical Features :1/ Ear discharge 2/ Hearing loss: conductive, Perforation, role of round window, baffle effectSlide 11: 3/Perforation: small,medium,large 4/ Middle ear mucosa and formation of polyp.CSOM( TT): CSOM( TT)Slide 13: Investigation: 1/ Examination under Microscope 2/ swab for C/S 3/Hearing test 4/CT Scan?Slide 14: Treatment: Aural toilet Ear drops. gentisone HC ear drops, lying and prssure on tragus.1.5% acetic acid ear drops( pseudomonas acid ph nasal allergy,infected tonsils, sinusitisSlide 15: Surgical Treatment, aural polyp, Dry perforation MyringoplastySlide 17: Atticoantral: Csom affecting Posterosuperior part of P/T, attic,antrum, and mastoid. Causes bone erosion.. high risk of complications.Slide 18: Pathology:1/ how the retraction pocket forms ,role of OME. 2/Role of keratinized squamous epithelium 3/ bone erosion, proteolytic enzymes,Slide 19: 3/ Osteitis: granulations,leads to bleeding and fleshy polyp. 4/ cholesterol granuloma. cholesterol from blood and giant cell grnulomaSlide 20: Presentation in the clinic: 1/ Ear discharge, scanty and foul smellingSlide 21: 2/ Hearing loss; may be normal erosion of incudostapedial joint conductive deafness sensorineural +conductive (mixed)Slide 22: blood stained discharge ..granulations or polypSlide 23: Signs : otoscope (clean the ear) attic or postero superior. crusting and small wax in attic may be masked.Slide 24: Retraction pocketSlide 25: Choleatetoma white flakes of squamous epithelium in retraction pouchSlide 26: investigation: Examination under microscope for assessment swab for c/s CT scan MastoidSlide 27: Surgery : remove the disease and second to reconstruct the ossicular assemblySlide 28: Mastoidectomy 1/ canal wall down: Radical(all ossicles removed) modified radical(ossicles saved) 2/ canal wall up; combined approach ....Slide 30: Conservative management, if limited disease or very old age . suction clearance under microscope You do not have the permission to view this presentation.
