Crouzon Syndrome
Patients with Crouzon syndrome sometimes exhibit malformations of the external ear and/or the middle ear, such as malalignment of the pinna (Peterson-Falzone et al., 2001). Literature has suggested that persons with Crouzon syndrome typically have conductive hearing loss caused by middle ear effusion (or fluid in the middle ear) and perforation to ossicular fixation (ossicles), intratympanic bony masses (tympanic membrane), ossicular anomalies, and closure of the oval window. Patients with a sensorineural hearing loss have also been reported, but are less likely to occur.

Famous quotes containing the word syndrome:
“Women are taught that their main goal in life is to serve others—first men, and later, children. This prescription leads to enormous problems, for it is supposed to be carried out as if women did not have needs of their own, as if one could serve others without simultaneously attending to one’s own interests and desires. Carried to its “perfection,” it produces the martyr syndrome or the smothering wife and mother.”
—Jean Baker Miller (20th century)
