Carefully blunt incision was then given to separate ear canal attachment with tympanic cavity
Thus, the tympanic cavity
and the ossicular chain can vibrate freely and function normally.
30) However, as is the case with other office-based myringoplastyprocedures, exploration of the tympanic cavity
cannot be performed during platelet-rich plasma placement, and the integrity and mobility of the ossicular chain cannot be tested.
CT scan was rechecked and showed soft tissue in the right mastoid and tympanic cavity
, with an irregular osteolytic area involving tympanic cavity
, zygomatic root, and zygomatico temporal junction [Figure 1]b.
The retrotympanic spaces is a complex structure lying in the posterior aspect of the tympanic cavity
Analysis of the patterns of extension of cholesteatoma, showed that the tympanic cavity
was involved in (91.
Cholesteatoma is a mass formed by the keratinizing squamous epithelium in the tympanic cavity
and/or mastoid and subepithelial connective tissue and by the progressive accumulation of keratin debris with/without a surrounding inflammatory reaction.
Chronic suppurative otitis media has been traditionally described as a chronic inflammation of part or the entire tympanomastoid compartment comprising of Eustachian tube, the tympanic cavity
, the mastoid antrum and all the pneumatized spaces of temporal bone associated with perforation of the tympanic membrane and otorrhoea.
On otoscopy, a whitish retrotympanic mass was seen occupying the posteroinferior portion of the tympanic cavity
in the left ear (figure 1).
Minimal dependent CT low dense collection with mucosal thickenings noted in left tympanic cavity
with intact ossicular chain and scutum.
The most common malignant tumor in the middle ear is squamous cell carcinoma, which typically arises in the external ear canal and then extends from there into the tympanic cavity
, the mastoid, or anteriorly.
Tympanosclerosis usually involve the ossicular joint but it may also involve the other part of tympanic cavity
like ossicle, round window niche, oval window,  stapes footplate and leads to fixation of ossicles causing hearing loss.
The paint mark in the sinus tympani was placed by reversing the orientation of the temporal bone, which allowed for better visualization of the posterior tympanic cavity
The tumor eroded the hypotympanum and tympanic cavity
and extending into the external ear.
The genu lies anterior to and inferior to the cochlea and tympanic cavity
