The terms atelectasis or sometimes adhesive otitis media can be used to describe retraction of a large area of the pars tensa. Tympanic membrane retraction is fairly common and has been observed in one quarter of a population of British school children. [1] Retraction of both eardrums is less common than having a retraction in just one ear.
Atelectasis is the partial collapse or closure of a lung resulting in reduced or absence in gas exchange. It is usually unilateral, affecting part or all of one lung. [2] It is a condition where the alveoli are deflated down to little or no volume, as distinct from pulmonary consolidation, in which they are filled with liquid.
The other main type is otitis media with effusion (OME), typically not associated with symptoms, [1] although occasionally a feeling of fullness is described; [4] it is defined as the presence of non-infectious fluid in the middle ear which may persist for weeks or months often after an episode of acute otitis media. [4]
Otitis interna, or labyrinthitis, involves the inner ear. The inner ear includes sensory organs for balance and hearing. When the inner ear is inflamed, vertigo is a common symptom. Other symptoms in adults include pain and drainage from ear or problems with hearing. [8]
Middle ear barotrauma (MEBT), also known to underwater divers as ear squeeze and reverse ear squeeze, is an injury caused by a difference in pressure between the external ear canal and the middle ear. It is common in underwater divers and usually occurs when the diver does not equalise sufficiently during descent or, less commonly, on ascent.
Image shows early occurrence of tracheal deviation. Tracheal deviation is a clinical sign that results from unequal intrathoracic pressure within the chest cavity.It is most commonly associated with traumatic pneumothorax, but can be caused by a number of both acute and chronic health issues, such as pneumonectomy, atelectasis, pleural effusion, fibrothorax (pleural fibrosis), or some cancers ...
Main symptoms of swimmer’s ear are a feeling of fullness in the ear, itchiness, redness, and swelling in or around the ear canal, muffled hearing, pain in the external ear and ear canal and especially a smelly discharge from the ear. [9] Constriction of the ear canal from bone growth (Surfer's ear) can trap debris leading to infection. [10]
Atelectasis occurs when distending pressure of the alveolus is overcome by surface tension of fluid within the alveolus. Repeated atelectasis and re-inflation leads to atelectotrauma . Atelectotrauma , atelectrauma , cyclic atelectasis or repeated alveolar collapse and expansion ( RACE ) are medical terms for the damage caused to the lung by ...
