摘要:

An instance of Bell's palsy with complete flaccid peripheral facial paralysis at one year with surgical confirmation by total facial nerve decompression and incision of the intratemporal facial nerve sheath confirmation is presented. This individual, with a most unusual duration of total facial paralysis in an instance of Bell's palsy, nevertheless developed eventual recovery typical of the delayed recovery from Bell's palsy, with considerable improvement in facial symmetry at rest, eyelid closure, and facial motion.

摘要:

The vascularity of the facial canal in the rat was studied with the microcorrosive technique and scanning electron microscopy. The vascular casts thus created demonstrated the larger feeding vessels and the extrinsic vascular supply, but gave above all a good three-dimensional comprehension of the fine blood vessels within the nerve proper, the intrinsic vascular supply.The facial nerve is supplied by a rich anastomosing network of these fine blood vessels. Vascular loops and arteriovenous anastomoses are common, thus avoiding the creation of end-arterial systems. The blood vessels of the facial nerve also communicate widely with the rest of the temporal bone through small bony canals present in the lining of the facial canal. The architecture and distribution of the fine blood vessels are of great clinical interest, especially with regard to the etiology of idiopathic peripheral facial palsy, since it is at this level that the exchange of fluids, elecrolytes, and metabolites takes place.

摘要:

This study investigated whether (1) health care providers (nursing home and hospital staff personnel) and elderly peer observers formed negative initial impressions of elderly persons shown in three conditions of hearing aid use; (2) whether the groups differed in their ratings; and (3) whether size of the aid affected their ratings. Stimuli were 36 photographic slides, three each of six male and six female elderly persons shown wearing a body hearing aid, a postauricular aid, and no aid. Observers rated the 12 stimulus subjects on a 16-item semantic differential. Factor analysis of the ratings resulted in three factors: achievement, personality, and appearance. Analysis of variance revealed that no “hearing aid effect” was present, since none of the observer groups rated the stimulus subjects lower on any of the three factors when they were shown wearing hearing aids. Further, the groups did not differ in their observations, and size of the hearing aid did not affect their ratings. The findings differ somewhat from earlier studies and have implications for counseling potential hearing aid users.

摘要:

A wide variety of benign and malignant middle ear masses have been reported in the literature. We present here an example of a previously unreported type of lesion, a case of hypertrophy of striated muscle, probably the tensor tympani muscle, presenting as a middle ear mass in a 17-year-old male. Clinical evaluation revealed a marked conductive hearing loss and eustachian tube obstruction.

摘要:

Fibrous dysplasia of the temporal bone is uncommon. When it does occur, surgery may be necessary because of cholesteatoma or chronic infection behind bony obstruction of the external auditory canal. Cosmetic surgery may also be performed because of bony deformity. When a surgical procedure is undertaken for hearing improvement, special problems may be encountered. The case presented illustrates middle ear pathologic changes found with fibrous dysplasia and specific surgical difficulties.

摘要:

Congenital bony abnormalities of the inner ear may result in a communication between the middle ear and the subarachnoid space. Patients with this anomaly often present with recurrent meningitis associated with acute otitis media or with middle ear fluid. This article presents three cases of recurrent meningitis with open middle ear-subarachnoid space connections. The first two cases involve a cerebrospinal fluid leak into the middle ear via the oval window, both patients having a Mondini-type of inner ear deformity. The pathway in the third case opened into the middle ear along the horizontal portion of the facial nerve.Computed tomoography (CT) scanning with metrizamide and differential density calculations helped to identify the abnormal pathway and to confirm that the leak has been closed postoperatively. Use of the CT scanner in these cases can be helpful in planning the surgical closure and in postoperative follow-up.

摘要:

Chondrodermatitis helicis is a benign, painful lesion of the auricle affecting the elderly population, particularly men. These lesions usually affect the helix of the ear, although the antihelix and, less commonly, the antitragus may be involved. The lesions are most frequently unilateral, although bilateral involvement has been reported. An unusual case of bilateral involvement of the antitragus is presented. The etiologic and pathologic manifestations are reviewed and current treatment modalities outlined.
