9 R L Tympanic membrane

10 Otoscopy (normal findings) Hairs Wax Hump Keratin Blood vessels Collapsed external canal in old age

11 Removal of ear wax

12 Foreign Bodies Bead Bee

13 Chronic External Otitis (skin maceration & keratosis) Acute External Otitis (hyperemia & edema)

14 TRAUMATRAUMA External canal clot Hemotympanum Perforation Self-inflicted perforation

15 Otomycosis Otomycosis fungal ball wet-newspaper like appearance

16 Diabetic Ear necrosis & granulations on the floor of the external auditory canal

17 Neoplasms of the external auditory canal & auricle Exostosis Osteoma Cancer Rodent ulcer

18 Acute Otitis Media (hyperemia, bulging, perforation & finally drainage)

19 OMEOME Otitis media with effusion (OME) retracted tympanic membrane, fluid level, some air bubbles, no perforation)

20 TubesTubesGrommetGrommet Grommet T-tube

21 Sequelae of non- resolved otitis media Retraction pocket Tympanosclerosis Atelectasis Attic erosion

22 Bullous Myringitis bullae on outer surface of tympanic membrane

23 Perforation of the tympanic membrane (picture on the right)

24 Tubotympanic otitis media (central perforation)

25 Atticoantral otitis media (cholesteatoma)(marginal perforation)

26 Cholesteatoma scanty offensive purulent aural discharge from an attic or posterosuperior marginal perforation with possible cranial or intracranial complications

27 Mastoid abscess & fistula

28 Aural polyp pedunculated middle ear mucosa or granulation tissue

29 Glomus Pulsating tinnitus & a red mass behind an intact tympanic membrane

30 Otoscopic examination in Otosclerosis: Schwartze’s sign (flamingo red) Usual finding is a normal tympanic membrane
