OBJECTIVE
The presence of endolymphatic hydrops in the inner ear, which can be detected with gadolinium-enhanced magnetic resonance imaging (Gd-MRI), is widely recognized as the main pathological cause of Ménière's disease (MD). However, the precise mechanisms underlying the development of
After operation three consecutive phases can be observed: 1. thickening of epithelial cell layer with development of edema in the submucosa, 2. metaplasia of epithelium with formation of ciliated and goblet cells, concomitantly round cells are found in the submucous tissue, 3. regression of
BACKGROUND
Otitis media may predispose for retraction pathologic abnormality later in life. A weakening of the collagen fiber bundles in the lamina propria of the tympanic membrane (TM) is a prerequisite for the formation of a retraction pocket. Various collagen types have different tensile
OBJECTIVE
To investigate the clinical symptoms, diagnosis and treatment of congenital petrous apex cholesteatoma.
METHODS
A retrospective review of clinical symptoms, image findings and effect of operation in nine patients with congenital petrous apex cholesteatoma were
OBJECTIVE
The current study aimed to analyze changes of the acoustic stiffness properties and coincident morphologic changes of the tympanic membrane (TM) in early stages of cholesteatoma. The results were compared with those obtained in previous studies of otitis media with effusion and purulent
Objective:To summarize the clinical characteristics, the surgical methods and the recovery of facial nerve function outcomes in patients with the middle ear cholesteatoma complicated with peripheral facial paralysis.Method:Retrospective analysis method was used on patients treated for middle ear
OBJECTIVE
To assess the effectiveness of glass ionomer bone cement (GIBC) in lateral attic wall reconstruction after primary acquired attic cholesteatoma surgery.
METHODS
This prospective study was conducted on twenty children collected from the ENT outpatient clinics of a secondary and tertiary
OBJECTIVE
To investigate the ultrastructure of the chorda tympani nerve and analyze the taste and facial nerve functions in patients with cholesteatoma.
METHODS
1. The tympanic segments of chorda tympani nerves were collected for ultrastructural investigations in 19 cholesteatoma cases who underwent
Lymphatic vessels were few in the edematous portion of the cholesteatoma perimatrix of the human middle ear. But the lymphatic vessels contained mucus and consisted of degenerated endothelial cells. Edema of the perimatrix was considered to be caused by the degeneration of lymphatic vessels. Normal
Imaging of middle-ear cholesteatoma with diffusion-weighted imaging (DWI) magnetic resonance imaging (MRI), and inner-ear endolymphatic hydrops (in Ménière's disease) with post-gadolinium high-resolution MRI, are reviewed. DWI MRI provides for a more specific diagnosis of tympano-mastoid
CONCLUSIONS
The clinical and surgical findings of this study indicated advanced cholesteatoma in many patients with facial paralysis. The outcome of facial paralysis was good. Poor outcomes were observed in cases with petrosal cholesteatoma and in those who underwent surgery > or = 2 months after
Sensorineural hearing loss is generally felt to be an untreatable medical condition. However, in some cases, prompt diagnosis and treatment of the underlying condition may reverse the deafness. This article summarizes various treatable forms of sensorineural hearing loss and provides illustrative
An animal model for pneumococcal otitis media was studied histologically at varying intervals postinoculation. Histologic changes generally associated with acute inflammation (edema, diffuse infiltration with polymorphonuclear leukocytes, and hemorrhage) occurred early in the disease while the ears
OBJECTIVE
We hypothesized that there would be significant anatomic differences of the tensor tympani muscle (TTM), tympanic diaphragm, epitympanum, and protympanum in patients with versus without Menière's disease.
BACKGROUND
The effects of tenotomy on Menière's disease suggested it relieves the
