Involutional stenosis is probably the most common cause of nasolacrimal duct obstruction in older people. It affects women twice as frequently as men. Although the inciting event in this process is unknown, clinicopathologic study suggests that compression of the lumen of the nasolacrimal duct is caused by inflammatory infiltrates and edema.
Persons with dry eye conditions can be fitted with punctal plugs that seal the ducts to limit the amount of fluid drainage and retain moisture. During an ear infection, excess mucus may drain through the nasolacrimal duct in the opposite way tears drain. [citation needed] In humans, the tear ducts in males tend to be larger than the ones in ...
Strictures are the second most common cause of chronic obstructive sialadenitis, after salivary stones. [1] In line with this, strictures may give rise to the "meal time syndrome", [ 1 ] where there is pain and swelling of the involved salivary gland upon salivary stimulation with the sight, smell and taste of food.
The signs of a sinus infection are typically congestion, facial pain, and pressure around the sinuses. “The reason why there’s pain and pressure is because those little rooms (the sinuses) are ...
Dacryocystitis is an infection of the lacrimal sac, secondary to obstruction of the nasolacrimal duct at the junction of the lacrimal sac. [1] The term derives from Greek dákryon 'tear' cysta 'sac' and -itis 'inflammation'. [2] It causes pain, redness, and swelling over the inner aspect of the lower eyelid and epiphora.
A salivary diverticulum (plural diverticuli) is a small pouch or out-pocketing of the duct system of a major salivary gland. [16] Such diverticuli typically cause pooling of saliva and recurrent sialadenitis, [17] especially parotitis. [18] A diverticulum may also cause a sialolith to form. [19] [20] The condition can be diagnosed by ...
Nasal obstruction characterized by insufficient airflow through the nose can be a subjective sensation or the result of objective pathology. [10] It is difficult to quantify by subjective complaints or clinical examinations alone, hence both clinicians and researchers depend both on concurrent subjective assessment and on objective measurement of the nasal airway.
This can be a result of obstruction of salivary ducts by microliths (due to associated intercurrent infections), or a result of immune reaction with the formation of secondary lymph follicles. [10] Chronic sclerosing sialadenitis is characterised by presence of three major criteria of [ 11 ] dense lymphoplasmacytic infiltrate, storiform pattern ...
