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.
We believe it is necessary to confirm a ventilation route during surgery if no aeration of the tympanic cavity
is seen on preoperative CT scan and to consider performing additional procedures, such as granulation tissue or curable lesion removal, to maintain the ventilation route.
Normal appearance of mucosa in the tympanic cavity
Soft, tissue-dense, non-contrast-enhancing material filled the left external auditory meatus and tympanic cavity
This combined approach allows complete removal of debris and inflamed epithelium from chronically diseased ear canal tissues and permits exposure of tympanic cavity
thus minimizes occurrence of post infections on surgical wound.
Congenital cholesteatoma originate from embryonic epithelial remains, tend to occur in the anterior tympanic cavity
, proximal to the epitympanum or stapes8.
A computed tomography (CT) examination showed the tympanic cavity
and the bone of the external auditory canal were not involved (Fig.
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.
vellerosus, the relative size of their tympanic cavity
was similar in both species.
Attic cholesteatoma is a result of the retraction of the pars flaccida or Shrapnell membrane, extending to the attic, going through the aditus, and eventually reaching the antrum, mastoid, or tympanic cavity
