Diagnosis Kerja
Otomycosis canalis auditorius externus dextra disertai otitis media supuratif kronis inaktif
Management
Aural toilet – menghilangkan debris dan kering
Krim miconazole di aplikasikan dengan cotton bud 3 kali sehari
Edukasi:Liang telinga di jaga tetap keringJangan sering korek2 dengan cotton budControl dalam seminggu
Prognosis
Bonam = 90% response bagus terhadap krim miconazole (Alnaweish S et al, 2011)
Bisa kemungkinan untuk rekuren Bisa menyebabkan komplikasi bila tidak
di tangani: perforasi membran tympani, trombosis mikotik dan membran tympani menjadi avaskuler

Pembahasan
Definisi otomycosis:“Otomycosis is a fungal infection of the skin of the external canal. Although fungi may be the primary pathogens, they are usually superimposed on chronic bacterial infection of the external canal or middle ear” – Bailey, 2006
Pembahasan
Tiga komponen yang membantu pertumbuhan fungus yaitu: moisture, warmth and darkness
Penyebab paling sering ada lah oleh Aspergillus sp. dan Candida Albicans (dermatophytes – keratinase)
Bersifat non pathogen selama terdapat keseimbangan antara sistem pertahanan tubuh dengan berbagai organisme tersebut
4 macam pathogenesis: OCTA (Obstruksi, Cerumen, Trauma, Asam)
Faktor predisposisi
- -Daerah tropis: CAE jadi lembab- - Diabetes Mellitus
- Pemakaian antibiotik/steriod jangka panjang- Gangguan imun berat- Wanita hamil : Kenaikan Estrogen dan Progesterone- Stress- Pemakaian tetesan kuping- Renang
Kenapa tempat tropis?
Fungi are abundant in soil or sand that contains decomposing vegetable matter. This material is desiccated rapidly in tropical sun and blown in the wind as small dust particles. The airborne fungal spores are carried by water vapours, a fact that correlates the higher rates of infection with the monsoon, during which the relative humidity rises to 80%.
Then the environmental temperature exceeds 100° F and relative humidity exceeds 70%, the skin tends to become macerated predisposing this structure to infection (Satish H.S et al, 2013)
DONT APPLY OIL
Unless indicated for example to soften cerumen in action of aural toilet. Disturb the lipid acid environment of CAE
Apopilosebaceous unit
Apocrine Hair follicle Sebaceaous gland
Cerumen
In health, the external auditory canal is well protected and self cleansing structure but several factors, either singly or in combination, predispose the ear canal to otitis externa. Absence of cerumen may lead to infection for two reasons.
1. Act of cerumen removal may be traumatic and lead to breaks in the fragile external auditory skin.
2. Cerumen serves as antimicrobial role through physically protecting the extemal auditory canal skin, establishing a low ph, inhospitable enviroment for pathogens, and producing antimicrobial compounds such as lyzosyme so that its absence leaves the canal vulnerable to infection. Cerumen maybe removed physically by cleaning or through syringing but water in the canal both macerates the underlying skin and raise the pH of the canal.
Anatomy CAE
Superior adalah fossa cranialis media Posterior adalah tympanic bone, yang
memisahkan CAE dengan mastoid Anterior fossa glenoidalis of TMJ dan
parotid gland Inferior, Infratemporal fossa
Pathophysiology
Obstruction of the drainage of glands into the follicular canal and subsequently into the external canal is the primary factor in the pathogenesis of external otitis.
This obstruction intracellular oedema Inflammatory response to increased
environmental temperature and humidity Uncomfortable sense of fullness which leads to
sense of itching . Scratch and this act disrupts surface epithehum
allowing contamination by surface microbes
Pathophysiology
That sets the stage Usually sets for bacteria, so superimposed otitis
externa. Fungi sometimes set the stage Pre-inflammatory: the set stage Inflammatory: Lumen narrowing, serous secretion Chronic: Hyperkeratosis and acanthosis Many cases of otomycosis are actually mixed
bacterial and fungal infections , the most common bacterial isolates being Staphylococcus aureus , Psuedomonas species and Proteus species.
Differensiasi antara OE
OED Otomycosis• Otalgia + fullness• Nyeri• Oedema (+)• CAE menyempit dan hyperemis
• TM Hyperemis
• Gatal• Debris (+)• Rasa penuh pada telinga•Otorrhea•Titik-titik Putih/Hitam/abu-abu
• TM Normal
Otitis externa
Diffuse Furunculosis Chronic Maligna (necrotizing) Otomycosis Eczematous
Pemeriksaan KOH?
Antimycotic
Specific: Myconazole, clotrimazole, nystatin dll. Non-specific: solusi acidifying and dehydrating:
Asam boric 2%Aluminium sulfat-kalsium asetatGentian violet (di toleransi dengan baik oleh pasien dengan cavitas mastoid)Metacresyl acetate (pakai microscope)
Antibiotik dan steroid tidak dapat membantu menyembuhkan otomikosis tetapi akan meningkatkan pertumbuhan jamur khususnya Candida.
Bagaimana dengan OMSK?
Tanpa tanda-tanda inflamasi (nyeri, discharge, bengkak mukosa)
Bila ada discharge wet/draining form acute
Prognosis: baik bila kering, bisa biasanya tanpa keluhan
Apakah perlu tympanoplasty? (Paper patch)Monitor untuk infeksi rekuren dan cholesteatoma Bahan dari fascia temporalis/perichondrium auricle/irisan tipis cartilago fibrin glue
Otitis media
Acute/Recurrent Otitis media with effusion (OME)
acute(3w)/subacute(3m)/chronic ~ HL(Adults: SAS, Tumors)
Chronic Suppurative otitis media (CSOM/OMSK)
Chronic otitis media with cholesteatoma (primary acquired cholesteatoma/Secondary acquired)
