“…Reports of congenital cholesteatoma have been given by a series of authors, following the first description (House, 1953;Tytus and Pennybacker, 1956;Cawthorne and Griffiths, 1961;Cawthorne, 1963;Derlacki and Clemis, 1965;Derlacki et al, 1968;Derlacki, 1973Derlacki, , 1977House and Sheeny, 1980;Wehrs, 1983;McDonald etai, 1984). A review of the literature shows that cholesteatoma of the petrous pyramid usually presents with sensorineural deafness, facial palsy or spasm, and vertigo.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…Many otologists believe that attic cholesteatomas originate in the external canal skin, invading (or invaginating) the attic through a pre-existing perforation, or that they are extensions of the atelectatic retraction pockets mentioned earlier (Nager 1925, Ojala & Saxen 1952, Fernandez & Lindsay 1960, McGuckin 1961, Buckingham 1968, Lim & Saunders 1972. This is a simple, uncomplicated and, seemingly, logical explanation; however, others look upon it as an oversimplified one (Virchow 1855, Wingrave 1910, Cushing 1922, Holmes 1938, McKenzie 1931, Tumarkin 1938, Diamant 1948, 1952, Cawthorne 1963.…”

“…Virchow (1855), Cushing (1922), Holmes (1938), McKenzie (1931), Diamant (1948Diamant ( , 1952) and Cawthorne (1963) have also looked for the origin of cholesteatoma in the attic. Some of them postulated an 'awakening of ectodermal embryonic rests' in the attic; this is the so-called 'congenital theory' (Cawthorne 1963, Derlacki & Clemis 1965 which postulates that some, or all, attic cholesteatomas are epidermoid cysts arising from embryonic rests. From this it would also follow that these cysts are primarily formed in the attic and eventually will or may burst out into the external canal.…”

“…From this it would also follow that these cysts are primarily formed in the attic and eventually will or may burst out into the external canal. While attic cholesteatomas unconnected to the external ear have periodically been described (Cawthorne 1963, Derlacki & Clemis 1965 and termed congenital cholesteatomas, the embryonic rests which are supposed to be their forerunners (Peron & Schuknecht 1975) have so far not been demonstrated. The basic reason for this 'embryonic rest' theory is the need to explain the presence in an endodermal environment (i.e.…”

“…It may be a chance finding by skull radiography, showing a defect in the petrous pyramid, mastoid, or middle ear regions. Cawthorne and Griffith (1961) and Cawthorne (1963) reported facial paralysis as an important presenting symptom of congenital cholesteatoma. Derlacki (1973) has a third report of congenital cholesteatoma of the middle ear and mastoid (previous reports, 1965 1968).…”
