Whilst hearing loss is a common symptom in many diseases of the ear, for example in otosclerosis (abnormal bone growth in the ear), [3] the white, chalky patches on the tympanic membrane are fairly characteristic of tympanosclerosis. Cholesteatoma is similar in appearance but the whiteness is behind the tympanic membrane, rather than inside.
Infection usually begins in the mouth or nose and enters the central nervous system via the eyes. [5] If the fungal infection begins in the nose or sinus and extends to brain, symptoms and signs may include one-sided eye pain or headache, and may be accompanied by pain in the face, numbness, fever, loss of smell, a blocked nose or runny nose.
If the sinus passage remains blocked, there is a chance that sinusitis may result. [6] If the mucus backs up through the Eustachian tube, it may result in ear pain or an ear infection. Excess mucus accumulating in the throat or back of the nose may cause a post-nasal drip, resulting in a sore throat or coughing. [6]
Although the disease is easily treatable, in severe cases boils may form inside the nostrils, which can cause cellulitis at the tip of the nose. The condition becomes serious because veins at that region of the face lead to the brain, and if bacteria spreads to the brain via these veins, the person may develop a life-threatening condition called cavernous sinus thrombosis, which is an ...
However, some researchers argue that the flow of mucus down the back of the throat from the nasal cavity is a normal physiologic process that occurs in all healthy individuals. [1] Some researchers challenge post-nasal drip as a syndrome and instead view it as a symptom, also taking into account variation across different societies.
Polyps arise from the lining of the sinuses. Nasal mucosa, particularly in the region of middle meatus becomes swollen due to collection of extracellular fluid. This extracellular fluid collection causes polyp formation and protrusion into the nasal cavity or sinuses. Polyps which are sessile in the beginning become pedunculated due to gravity ...
The mucous membrane is thickest, and most vascular, over the nasal conchae. It is also thick over the nasal septum where increased numbers of goblet cells produce a greater amount of nasal mucus. It is very thin in the meatuses on the floor of the nasal cavities, and in the various sinuses. It is one of the most commonly infected tissues in ...
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 structures. Hearing impairment can occur due to Eustachian tube blockage causing middle ear effusion.
