Otosclerosis is a condition of the middle ear where portions of the dense enchondral layer of the bony labyrinth remodel into one or more lesions of irregularly-laid spongy bone. As the lesions reach the stapes the bone is resorbed , then hardened ( sclerotized ), which limits its movement and results in hearing loss , tinnitus , vertigo or a ...
It results from disease of one lung, one major bronchus, or chronic congestive heart failure that affects only a side of breathing. Patients with trepopnea in most lung diseases prefer to lie and sleep on the opposite side of the diseased lung, as the gravitation increases perfusion of the lower lung.
Mixed hearing loss is a combination of conductive and sensorineural hearing loss. Chronic ear infection (a fairly common diagnosis) can cause a defective ear drum or middle-ear ossicle damages, or both. In addition to the conductive loss, a sensory component may be present. Central auditory processing disorder
The differential for diffuse shadowing is very broad and can defeat even the most experienced radiologist. It is seldom possible to reach a diagnosis on the basis of the chest radiograph alone: high-resolution CT of the chest is usually required and sometimes a lung biopsy. The following features should be noted:
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.
Chest x-ray of infant showing CPAM in the left lung causing a mediastinal shift towards the right. The cysts appear as bubbles in the left lung. Congenital pulmonary airway malformation (CPAM) is a rare disease in which the lung airways develop abnormally in the fetus. This leads to infants having pockets of air and cystic masses in their lungs.
The Rinne test (/ ˈ r ɪ n ə / RIN-ə) is used primarily to evaluate loss of hearing in one ear. [1] It compares perception of sounds transmitted by air conduction to those transmitted by bone conduction through the mastoid.
Either one side of the lung fails completely, leading to pulmonary aplasia, or one side of the lung is underdeveloped, leading to dysplasia or hypoplasia. [11] These defects occur during the early stage of lung development, although not as early as bilateral pulmonary agenesis, when respiratory primordium bifurcates into right and left ...
