The tympanic membrane has an elliptical shape and completely isolates the middle ear from the outer ear canal.
Has a dual function:
-barrier, protecting l ’ middle ear infections
-amplify sounds and pass them on to the auditory ossicles.
And’ consisting of three layers: skin on the external side, connective tissue and mucous layer on the internal side.
The membrane can go in against such a perforation or infection or a trauma ’. Continue reading
Many cancers of the head and neck are characterized by an early spread to lymphatic structures. Some malignant cells can move through the lymphatic vessels and accumulate all ’ in a lymph node, where they can grow and give an inflammatory reaction that will increase the size of the lymph node/infectious and we speak then of Lymphadenopathy.

The turbinates are bone covered with mucous membrane that define the lateral wall of the nasal cavity. In each nasal passage there are 3 the turbinates are always present (bottom, medium, top) and one accessory (Supreme).
The turbinates are able to increase or decrease their thickness checking blood flow of the submucosa: they can adjust the air flow ’. The inferior turbinates are mainly responsible for this phenomenon since the passage of the higher air ’ in the lower part of the nasal cavity. Continue reading
Nasal Ilsetto has two important properties: the first is to split the two nasal cavities by optimizing the passage of air ’, the second is to support the tip of the nose.
Nasal septum can punch for several reasons causing a variety of symptoms that can be of different severity based on the size, the shape and position of drilling. This condition can cause nasal respiratory obstruction, frequent nosebleeds, formation of abundant crusts, It can promote the formation of rhinosinusitis, You may have hissing during nasal breathing, perception of odors (cacosmia) and, rarely, the fall of the tip of the nose.
The term ’ means sinusitis inflammation of one or more paranasal sinuses, which are the cavities face covered with mucosa, full d ’ air and communicating with the nasal cavities. You recognize the maxillary sinuses, ethmoidal cells, the sphenoid and frontal sinuses.
Healthy mucous membranes produce small quantities of serum and mucus that protect the sinuses from infection, These secretions are normally drained through small Ostia to the nasal cavities.
A stagnation of secretions all ’ inside paranasal sinuses cause inflammation and encourages the development of bacterial colonies.
Most sinus infections are associated with rhinitis (rhinosinusitis), a more limited number of infections are associated with dental disease (Odontogenic sinusitis).
Most infections are caused by bacteria, less frequently sinusitis can be caused by fungus (fungal sinusitis).
