Soft, tissue-dense, non-contrast-enhancing material filled the left external auditory meatus
and tympanic cavity.
By the time of diagnosis, all patients had extensive necrosis of the external auditory meatus
in addition to a swollen and erythematous pinna.
The procedure adapted in our study was injecting local anesthetic agent just lateral to the bony cartilaginous junction at 3, 6, 9, and 12 o'clock positions aiming to get a clear field in case our instruments touched the external auditory meatus
. The margins of perforation were freshened, mucosa of middle ear was separated from tympanic membrane by curved needle, an incision made superior to the pinna just above the hairline and the graft was excised.
On examination, there were painful adherent crusts and scabs on the right pinna and external auditory meatus
and lower motor neuron facial palsy on the right side (as shown in the figure 1, 2 and 3).
We report a case of auricular ossification in a man who presented with left aural fullness, conductive hearing loss, and a stenotic left external auditory meatus
The prevalence of exostoses in the external auditory meatus
Examination revealed a firm, nontender lesion behind the left pinna and a large lesion in the conchal bowl that completely occluded the external auditory meatus
(figure 1, A).
The first branchial cleft becomes the external auditory meatus
, and the first branchial pouch gives rise to the middle ear and eustachian tube.
In this article, we share our experience with the use of an angled pediatric rigid endoscope during tympanoplasty to visualize the middle ear structure through the external auditory meatus
without the need for lowering the scutum.
Otoscopy identified what appeared to be a well-defined, skin-covered, 4-mm mass arising from the anteroinferior aspect of the external auditory meatus
. The rest of the ear canal and the tympanic membrane were normal.
Nonspecific inflammations are localized in the auricle, external auditory meatus
, and regional lymph nodes.
The tumor originated in the anterior wall of the tube near the pharyngeal ostium and protruded into the middle ear and external auditory meatus
. A similar lesion was also reported by Eichel and Hallberg.
