Unlike other forms of ear infections, we observe tenderness in outer ear [6] i.e., the pain of acute external otitis is worsened when the outer ear is touched or pulled gently. Pushing the tragus , the tablike portion of the auricle that projects out just in front of the ear canal opening, also typically causes pain in this condition as to be ...
In a small portion of individuals, the auricular nerve is the afferent limb of the Ear-Cough or Arnold Reflex. [ 3] Physical stimulation of the external acoustic meatus innervated by the auricular nerve elicits a cough, much like the other cough reflexes associated with the vagus nerve. Rarely, on introduction of speculum in the external ear ...
Lateral wall of nasal cavity, showing ethmoid bone in position. (Superior nasal concha is at top of pink region.) The superior nasal concha is a small, curved plate of bone representing a medial bony process of the labyrinth of the ethmoid bone. The superior nasal concha forms the roof of the superior nasal meatus. [1] : 692.
Brown is outer ear. Red is middle ear. Purple is inner ear. The auricula. Lateral surface. The outer ear, external ear, or auris externa is the external part of the ear, which consists of the auricle (also pinna) and the ear canal. [ 1] It gathers sound energy and focuses it on the eardrum ( tympanic membrane ).
Ear pain. Other names. Otalgia, earache. Examination of the ear canal and eardrum. Specialty. ENT surgery. Ear pain, also known as earache or otalgia, is pain in the ear. [ 1][ 2] Primary ear pain is pain that originates from the ear. Secondary ear pain is a type of referred pain, meaning that the source of the pain differs from the location ...
Eustachian tube dysfunction can be caused by a number of factors. Some common causes include the flu, allergies, a cold, and sinus infections. [ 6] In patients with chronic ear disease such as cholesteatoma and chronic discharge, studies showed that they have obstructive pathology at the ear side of the Eustachian tube. [ 7][ 5] Given that ...
Concha bullosa. A concha bullosa is a pneumatized (air-filled) cavity within a nasal concha, also known as a turbinate. [ 1] Bullosa refers to the air-filled cavity within the turbinate. [ 1] It is a normal anatomic variant seen in up to half the population. Occasionally, a large concha bullosa may cause it to bulge sufficiently to obstruct the ...
Nasal concha. Lateral wall of nasal cavity, showing ethmoid bone in position. (Superior and middle in pink, and inferior in blue.) In anatomy, a nasal concha ( / ˈkɒnkə /; pl.: conchae; / ˈkɒnkiː /; Latin for 'shell'), also called a nasal turbinate or turbinal, [ 1][ 2] is a long, narrow, curled shelf of bone that protrudes into the ...
