Moreover, the anterior part of the left temporal mastoid bone was also destroyed, while soft-tissue density shadow appeared at the left tympanic cavity
, mastoid, and external auditory canal.
In the middle of the 16th century, the anatomists Andreas Vesalius (1514-1564) and Giovanni Filippo Ingrassia (1510-1580) discovered the auditory ossicles in the tympanic cavity
of the human petrous portion.
Pus and granulations were also detected in the tympanic cavity
on that side.
Carefully blunt incision was then given to separate ear canal attachment with tympanic cavity
Postnatal development of the tympanic cavity
: a computer-aided reconstruction and measurement study.
Intraoperatively, a multilobulated greyish mass was filling the tympanic cavity
and extending posteriorly to the antrum.
A computed tomography (CT) examination showed the tympanic cavity
and the bone of the external auditory canal were not involved (Fig.1).
The Eustachian tube connects the tympanic cavity
to the nasal part of the pharynx, and its orifice lies on its respective lateral nasal pharyn-geal wall.
They most commonly arise from characteristic locations including the carotid bifurcation, the jugular fossa, tympanic cavity
, and the vagus nerve, but may rarely arise from other locations such as the larynx.
The middle ear is a hollow space in the temporal bone consisting of the tympanic cavity
, air cells of the mastoid process, and section of the auditory tube closer to the tympanic cavity
with bony walls.
* T = Tympanic cavity
(Mesotympanic spaces), o T1 = mesotympanum involvement without hidden recess involvement (Hypotympanum, retrotympanum, protympanum), o T2 =mesotympanic cholesteatoma with one hidden recess involvement (Hypotympanum, retrotympanum, protympanum) and o T3 = 2 or more hidden recess involvements
Patients for whom treatment was not effective or led to recurrence were given middle ear tympanoplasty and TT placement, followed by dexamethasone rinsing of the tympanic cavity
via the TT.
The aim of surgical treatment for chronic otitis media is to eradicate infection from the middle ear and mastoid bone, to aerate the tympanic cavity
, to reconstruct the sound-conduction mechanism, and to improve hearing acuity.
Microotoscopic examination showed a normal eardrum and tympanic cavity
, and audiometry revealed a conductive hearing loss on both sides; on the right, the average air-bone gap (ABG) was a mean of 34 dB on 0.5-1-2-3 kHz, while on the left side the mean ABG was 32 dB.
Analysis of the patterns of extension of cholesteatoma, showed that the tympanic cavity
was involved in (91.6%), mastoid cavity in (74%) and Eustachian orifice in (42%) of our patients.
