Atelectasis and Secretory Otitis Media

Abstract

That condition where the tympanic membrane is displaced toward the promontory is termed atelectasis. Thirty-seven patients (61 ears) showing various degrees of atelectasis graded from stage 1 to stage 4 were studied. Atelectatic drums are an inflammatory phenomenon occurring in underventilated ears. This conclusion is reached by considering the reversibility of the atelectasis upon ventilation; while the inflammatory factor can be deduced from the history and histopathology of the atelectatic drum, as well as the histology of the necrosed incus, the latter occurs in over a third of our cases. Also pneumatization of the mastoid is almost never present. Twelve (21%) of the ears treated did indeed develop a perforation at one time or another (two had cholesteatomas). Chronic granulating external otitis with specific features occurred in 15% of cases. The characteristics of these ears and their case histories lead us to view atelectatic ears as part of the otitis media syndrome, where their place is somehow transitional between secretory otitis media on the one hand and chronic otitis media on the other.

A Comparative Study between Pure Tone Audiometry and Impedance Audiometry Findings in Patients with Chronic Retracted Tympanic Membranes

“…Then they underwent otoscopic examination to evaluate their tympanic membranes. The retraction of the tympanic membranes was classified on the basis of Sade's Classification (1) .Patients then underwent a pure tone audiometry and their hearing loss was classified into mild, moderate, moderately severe, severe and profound as per WHO classification (6) . Patients then underwent an impedance audiometry to evaluate the compliance of their tympanic membranes.…”

“…The terms "atelectasis" or sometimes "adhesive otitis media" can be used to describe retraction of a large area of the pars tensa. Attempts have been made to categorise the extent of tympanic membrane retraction (1)(2)(3) though the validity of these classifications is limited (4) . However, the most commonly used classification for these Tympanic membrane retraction is Sade's Classification (1) .…”

The retracted part of the tympanic membrane may become adherent to structures in the middle ear, which hinders spontaneous resolution.…”

Ear Polyps in Posterior Superior Retraction Pockets, Herodion

“…All polyps were localized over a posterior retraction pocket and originated behind the posterior annulus in the posterior superior quadrant of the pars tensa. Because of its localiza tion and peculiar appearance, the polyp was denoted as herodion [5].…”

Transmyringeal ventilation tube treatment in children: Hearing outcome after 10 years

“…Thus, the children were 11-20 years at the time of examination. Registrations were made if any retractions in pars flaccida according to Tos et al were found [15], or in pars tensa according to Sadé et al [16], described in Fig 2 and Table 1, respectively. Furthermore, presence of myringosclerosis and the part of the eardrum affected as well as visible middle ear fluid, VTs or eardrum perforations were also registered.…”
