Early Stage of Infective Inflammation

Figure shows an increased vascularity and early inflammation of middle ear mucosa in reactivated otitis media (+).  Mucous level is seen anteroinferiorly (arrow). M- malleus handle.  Tympanic membrane still appears normal.

Chronic Suppurative Otitis Media (CSOM): Active Stage

Mucopus discharge in the presence of non-closure eardrum perforation

with intermittently or chronically-diseased middle ear mucosal linings.

Reactivation of otitis media following upper respiratory tract infection.

[(+) - mucopus]

Large central perforation with yellowish discharge.

Bare handle of malleus with active middle ear infection at the background.  

 

Greenish discharge in Pseudomonas sp. infection.

 Air bubbles within mucopurulent discharge to suggest presence of eardrum perforation. 

 Whitish fibrinous exudates overlying granulation tissue involving the handle

of malleus and corresponding medial wall of the tympanic cavity.

 

Granulations involving handle of the malleus with unhealthy perforation edges.

Hyperplastic middle ear mucosa with on-going infection.

Large posterior pars tensa perforation with mucopus seen along the external auditory meatus (+).  (A - anterior, P - posterior)

An active infection with double perforation of eardrum seen.

Medium-Size Eardrum Perforation in Chronic Suppurative Otitis Media (CSOM)

A medium-sized perforation (estimated 30%) with healthy middle ear mucosa.

A medium-sided perforation (estimated 25%) with thickened edges.  Myringosclerosis plaque seen involving the posterior-inferior quadrant of the TM.

 

 

Medium-size posterior pars tensa perforation in inactive stage. 

Large-Size Eardrum Perforation in Chronic Suppurative Otitis Media (CSOM)

 Large central perforation in inactive stage.  The middle ear

mucosa and hypotympanic air cells can be seen clearly.

 

Large central perforation showing the hypotympanum and Eustachian tube opening anterior-inferiorly.  Posterior pars tensa sclerosis and small fibrous nodule noted at the anterior edge of the perforation.

A very large central perforation with sclerotic plaques seen (+).

Large Eardrum Perforation, Myringosclerosis, and Anterior Bony Hump

Large central perforation in inactive stage with plaques of myringosclerosis superiorly in front and behind the handle of malleus.  Anterior bony hump is prominent which limits full view of the eardrum.

of its fibrocartilaginous annular ring is absent.

CSOM: The Role of Angled Otoendoscopy

 30/45 degree otoendoscopy are useful in the assessment of CSOM.  Its indications include to ascertain ossicular continuity, presence of adhesions, tympanosclerosis, and to look for potential residual focus of infection

prior to myringoplasty.

This image shows the the presence of mucopus from posterosuperior compartment of the middle ear and filling the round window niche.  The discharge is very likely arising from the aditus after it exits mastoid reservoir.

ear cavity focusing at eustachian tube opening (star).  White dots indicates

remnant of tympanic annulus of the eardrum in near-total perforation.

Ear Protection in CSOM

It is important to keep the ear dry to prevent recurring inflammation and subsequent re-infection of the middle ear mucosa in the presence of eardrum perforation.  Water, shampoo, soap, and body bath are amongst the usual agents which need attention.  The methods include wearing shower cap to cover the ear as well, packing the concha with cotton ball smeared with oil-based liquid or cream such as vaseline or olive oil, and using ear plug while taking shower.  Swimming and scuba diving are prohibited, and contact water sports are strongly discouraged until the perforation closed naturally or repaired..
