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.
Obstruction of the nasolacrimal duct may occur. [4] [5] [6] This leads to the excess overflow of tears called epiphora (chronic low-grade nasolacrimal duct occlusion). [7] A congenital obstruction can cause cystic expansion of the duct and is called a dacryocystocele or Timo cyst.
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.
Commonly reported are feelings of nasal obstruction, nasal dryness and crusting, and a sensation of being unable to breathe. [3] The overall incidence of ENS is unknown due to the small body of epidemiological study and the lack of a dedicated International Classification of Diseases (ICD-10) code, which would allow incidence reporting of the ...
The frontonasal duct is a duct through which either frontal sinus drains into the nasal cavity. [ 2 ] [ 3 ] Each frontal sinus opens into the frontonasal duct by an opening (the opening of frontal sinus or frontal sinus aperture [ 4 ] ) on the inferomedial part [ 3 ] of the floor of the sinus.

A rhinolith usually forms around the nucleus of a small exogenous foreign body, blood clot or secretion by slow deposition of calcium and magnesium carbonate and phosphate salts. Over time, they grow into large irregular masses that fill the nasal cavity. They may cause pressure necrosis of the nasal septum or lateral wall of nose.
Dacryocystocele (Dacryocystitis) or timo cyst is a benign, bluish-gray mass in the inferomedial canthus that develops within a few days or weeks after birth. The uncommon condition forms as a result as a consequence of narrowing or obstruction of the nasolacrimal duct, usually during prenatal development.
Cause, the open and closed approaches to rhinoplastic correction resolve: (i) nasal pathologies (diseases intrinsic and diseases extrinsic to the nose); (ii) an unsatisfactory aesthetic appearance (disproportion); (iii) a failed primary rhinoplasty; (iv) an obstructed airway; and (v) congenital nose defects and deformities.
