It is the salivary gland of greatest volume, located behind and below the external acoustic meatus
, partially covering the mandibular ramus and the masseter muscle, and it is closely related to the facial nerve that runs through it.
It consists of the auricle or pinna and the external acoustic meatus
. The lateral surface of the auricle is irregularly concave, faces slightly forward, and displays numerous eminences and depressions.
The most important causes of asymmetrical sensorineural hearing loss are neoplastic lesions in the internal acoustic meatus
, such as vestibular schwannomas or other cerebellopontine angle tumors, as well as multiple sclerosis, stroke and other non-neoplastic causes.
It has been suggested that the presence of foreign body in the external acoustic meatus
is a marker for SOM in children (6).
One of the main concerns relates to the possibility of an external acoustic meatus
(EAM) collapse when supra-aural headphones are positioned.

," Anatomical Science International, vol.
The Henle's Spine (HS)/spina suprameatica/spina suprameatalis/meatal spine or spina meatus, is a small bony prominence anterior to the supramastoid pit at the posterosuperior margin of the bony external acoustic meatus
Otitic cerumen and inspissated pus were collected from external ear close to external acoustic meatus
with the help of sterile swabs moistened with sterile saline solution, while aural discharges were collected with dry sterile swab to perform cytological examination, bacteriological and mycological culture to identify the etiological agents.
Surgeons, anatomists, and others from the US, Europe, Asia, Canada, and Qatar provide 21 chapters on the neurocranium and facial skeleton, skull base, soft tissues, arteries, veins, nerves, muscles, orbit, eyelid, nasal cavity and paranasal sinuses, external nose, auricle and external acoustic meatus
, oral cavity and pharynx, and neck, with drawings, interoperative photos, and radiologic images.
In all 53 patients, the bleeding sites were mostly localized in the posterior nasal dome of the inferior nasal meatus, with the large branches of the posterolateral nasal arteries distributed around the external lateral wall.10 Intermittent bleeding was observed before surgery or nasal packing, with blood effusion from the anterior naris, pharynx oralis, contralateral nasal cavity, affected eyes and the external acoustic meatus
; these are the typical clinical features of epistaxis in the posterior fornix of the inferior nasal meatus.
Carefully, herpetic vesicles, erythematous ulcerative, and crusted scars were observed around the left external acoustic meatus
. Brain magnetic resonance imaging (MRI), on admission [Figure 1], revealed a high signal intensity lesion involving basis pontis and medulla oblongata on both the T2-weighted image [Figure 1]b and fluid attenuation inversion recovery (FLAIR) [Figure 1]d.
