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.
[10] [7] Visual inspection can reveal mouth breathing, which is suggestive of nasal obstruction, or a horizontal crease across the nose (caused by the "allergic salute"). [ 10 ] In the absence of any specific diagnostic tests, it may be difficult to diagnose PND from history of symptoms alone, as the etiology is broad and the symptoms may be ...
Culturing of purulent discharge is advisable in acute presentations of sialadenitis to allow targeted antibiotic therapy. Full blood count if infection is suspected. Facial radiographs such as dental radiographic views should be taken to exclude an obstructive element due to presence of sialolith or evolving abscess.
Bleeding from the nose, also called epistaxis, may occur when the dried discharge (crusts) are removed. Septal perforation and dermatitis of nasal vestibule can occur. The nose may show a saddle-nose deformity. Atrophic rhinitis is also associated with similar atrophic changes in the pharynx or larynx, producing symptoms pertaining to these ...
Excess tears flow through the nasolacrimal duct which drains into the inferior nasal meatus. This is the reason the nose starts to run when a person is crying or has watery eyes from an allergy, and why one can sometimes taste eye drops. This is for the same reason when applying some eye drops it is often advised to close the nasolacrimal duct ...
Rhinitis is categorized into three types (although infectious rhinitis is typically regarded as a separate clinical entity due to its transient nature): (i) infectious rhinitis includes acute and chronic bacterial infections; (ii) nonallergic rhinitis [14] includes vasomotor, idiopathic, hormonal, atrophic, occupational, and gustatory rhinitis, as well as rhinitis medicamentosa (rebound ...
Blood-laced mucus from the sinus or nose area can sometimes be misidentified as symptomatic of hemoptysis (such secretions can be a sign of nasal or sinus cancer, but also a sinus infection). Extensive non-respiratory injury can also cause one to cough up blood. Cardiac causes like congestive heart failure and mitral stenosis should be ruled ...
Sinusitis, also known as rhinosinusitis, is an inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include production of thick nasal mucus, nasal congestion, facial congestion, facial pain, facial pressure, loss of smell, or fever.
