It was observed that in hypertension hearing is severely damaged. By analysis of the otological symptomatology in 50 hypertonic patients (42 women, 8 men) a bilateral hearing disorder was revealed in 47 subjects, a unilateral one in three subjects, otoscopy revealed dilatation of the artery supplying the handle of the malleus or even hyperaemia of Schrapnell's membrane. The patients reported low-frequency tinnitus, vertigo, pressure in the ears pain in the ears, headache, weather-dependence of complaints. In the initial stages roof-shaped type of audiometric curve was found, in the group were 45% mixed types of deafness. If during hypertension sodium is retained and the extracellular volume is enlarged, then in the inner ear the volume of perilymph increases in particular and this leads to impaired conduction through the inner ear fluids with affection of high and low frequencies, disorders of the conduction function of the fenestrae with the conduction component on the audiogram. Hypertension is for the organ of hearing an important risk factor in pre-disposed subjects with and affection of the inner ear is equally malignant and has a similar pathological background as glaucoma.

In elderly patients an unilateral sensorineural hearing loss is frequently associated with a relatively more patent eustachian tube on the involved side. A simple method of investigation is observation under the operating microscope during tubal inflation by the patient. In right-handed patients the abnormally patent tube most often lay on the left side. Powerful self inflation in these patients induces acute hearing loss and vertigo. Acute hearing loss is commoner on the left side. The air bone gap is greater at higher frequencies due to mobility of the stapes, loosening of the incudal joints and the tympanic membrane. In contrast the air bone gap is greater at lower frequencies in otosclerosis or malleus head ankylosis. Minor degrees improve after self inflation is prohibited. In most patients with abnormally patent eustachian tubes further therapy is not necessary after the patient has received precise advice. In only about 20% of the cases is the patient disturbed by a feeling of fullness in the ear, autophony and tinnitus. After stabilisation of weight and blood pressure, a septoplasty with correction of the posterior turbinates may reduce the exspiratory resistance. The most drastic treatment is a collagen injection around the tube. Patients with depression should be treated appropriately.

The aim of this study is to evaluate the anatomical details of the inner ear and middle ear, using multidetector row CT. Temporal bone CT scans were obtained using 16-detector row CT scanner (Lightspeed 16, General Electric Medical Systems, Milwaukee, WI) in 30 patients with dizziness, vertigo, or hearing loss. The three-dimensional (3D) images were reconstructed with volume rendering techniques. The 3D images were reviewed by two radiologists and scored by using a three-point quality rating for qualitative assessment of the 23 representative structures of the middle and inner ear. The malleus, incus, and facial nerve canal were identified in all patients. The incudomalleolar joint appeared fused in all patients. The stapes were seen clearly in 27 (90%) of 30 patients except in three patients. Among the three remaining patients, there was one who had effusions in the middle ear cavity. Another patient had left cholesteatoma. The third patient had normal middle ear cavity. The cochlea and the three semicircular canals (anterior, posterior, and lateral) were well demonstrated in 29 (97%) of 30 patients except for one old woman with osteoporosis. Sixteen-detector row CT imaging of temporal bone with advanced 3D reformation yields state-of-the-art anatomical details of the temporal region useful to address anatomical localization issues and ease conceptual structural learning.

Revision stapedectomy with a malleus grip prosthesis is a technically challenging otologic procedure. The prosthesis is usually longer and extends deeper into the vestibule than a conventional stapes prosthesis, creating the potential to affect the vestibular sense organs. The prosthesis also bypasses the ossicular joints, which are thought to play a role in protecting the inner ear from large changes in static pressure within the middle ear. The prosthesis is in close proximity to the tympanic membrane, thus increasing the risk for its extrusion. We reviewed our experience with revision stapedectomy with the Schuknecht Teflon-wire malleus grip prosthesis in 36 ears with a mean follow-up of 23 months. The air-bone gap was closed to within 10 dB in 16 ears (44%) and to within 20 dB in 26 ears (72%). The incidence of postoperative sensorineural hearing loss was 8% (3 ears). There were no dead ears. Extrusion of the prosthesis occurred in 1 case (3%). Nearly 50% of patients reported various degrees of vertigo or disequilibrium during the first 3 weeks after surgery. These vestibular symptoms resolved by 6 weeks in all but 1 case. We did not find evidence of damage to the inner ear due to the length of the prosthesis or due to the potential for direct transmission of changes in static pressures within the middle ear to the labyrinth. Our results are similar to those published in the literature for malleus attachment stapedectomy and conventional revision incus stapedectomy.
