Ophthalmology. Differential diagnosis. Tears arising from lacrimal sac fistula. [1] Nasolacrimal duct obstruction is the obstruction of the nasolacrimal ducts (better known as the tear ducts) and may be either congenital or acquired. Obstruction of the nasolacrimal ducts leads to the excess overflow of tears called epiphora.
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.
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 ...
Upper airway resistance syndrome (UARS) is a sleep disorder characterized by the narrowing of the airway that can cause disruptions to sleep. [1][2] The symptoms include unrefreshing sleep, fatigue, sleepiness, chronic insomnia, and difficulty concentrating. UARS can be diagnosed by polysomnograms capable of detecting Respiratory Effort-related ...
Nasal septum deviation is the most common cause of nasal obstruction. [6] A history of trauma to the nose is often present including trauma from the process of birth or microfractures. [ 6 ] A medical professional, such as an otorhinolaryngologist (ears, nose, and throat doctor), typically makes the diagnosis after taking a thorough history ...
Post-nasal drip. Post-nasal drip (PND), also known as upper airway cough syndrome (UACS), occurs when excessive mucus is produced by the nasal mucosa. The excess mucus accumulates in the back of the nose, and eventually in the throat once it drips down the back of the throat. It can be caused by rhinitis, sinusitis, gastroesophageal reflux ...
An upper respiratory tract infection (URTI) is an illness caused by an acute infection, which involves the upper respiratory tract, including the nose, sinuses, pharynx, larynx or trachea. [3][4] This commonly includes nasal obstruction, sore throat, tonsillitis, pharyngitis, laryngitis, sinusitis, otitis media, and the common cold. [5]: 28 ...
Ophthalmology. 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.
