Acupuncture treatment of chronic unilateral tinnitus--a double-blind cross-over trial.

In a double-blind controlled trial the effect of traditional Chinese acupuncture versus placebo acupuncture was evaluated among 17 patients (8 females and 9 males, mean age 45.7 years) with chronic (mean disease duration 5.3 years) unilateral tinnitus. None of the patients had any treatable otological disease. All patients suffered from daily tinnitus, the intensity of which was recorded by the patients themselves every day during a period of 15 weeks. Each patient was treated by traditional Chinese acupuncture as well as placebo acupuncture following randomization (Figure 1). Each period of treatment comprised 2 treatments a week for 3 weeks. Throughout the whole investigation a period effect was recorded, insignificant in the acupuncture-placebo group, but significant in the placebo-acupuncture group (Friedman analysis of variance) (Table 4). There was no significant difference between traditional Chinese acupuncture and placebo (Wilcoxon test, P greater than 0.05, one-tailed). There was no relation between the patients' subjective statements and the results of sound balance measurements as an objective standard of tinnitus (Spearman test).

Sensorineural hearing loss and somatic insufficiency.

Studies of clinical, audiometric and histological defects in patients with conductive otosclerosis, demonstrated the occurrence of subclinical manifestations in the hair, nails, joints and teeth. Light-microscopic examination of the skin in these patients has shown metachromasia of the ground substance and degenerative abnormalities in the collagen and elastic fibres. Structural abnormalities, in the organs developing from the ectoderm and mesoderm, led to the conclusion that otosclerosis is a universal disease characterized by ectomesodermal insufficiency, a somatic insufficiency. Optical measurement of the corneal thickness by corneometry has been introduced as an objective method for the diagnosis of somatic insufficiency. This method, now used routinely in our clinic, shows a high frequency of abnormal corneal thickness among patients with otosclerosis. Such a person is termed 'cornea-positive'. Cochlear otosclerosis with pure sensorineural hearing loss has been studied by X-ray in axial and semiaxial tomography. These patients were often X-ray positive and among them there were many cornea-positive individuals. Cases with noise-induced hearing impairment may also be cornea-positive, i.e. they may exhibit, somatic insufficiency indicating that their hearing organs are characterized by a decreased resistance to noise. Corneometry has shown its value in the diagnosis of insufficient somatic constitution typical of individuals at risk.

Hearing loss in children with abnormal corneal thickness.

Corneometry, i.e. measurement of the thickness of the centre of cornea, has been introduced as an objective method for the diagnosis of ecto-mesodermal insufficiency. A group of children, between 4 and 18 years of age with different types of hearing defects has been examined by this method and the results were evaluated separately for conductive and sensorineural hearing loss. Within the two groups, the cornea-positive children (i.e. children with abnormal corneal thickness) were analyzed in relation to the different diagnostic groups.

Psychological aspects of patients with binaural hearing aids.

9 of 10 persons with hearing defects can only overcome this handicap through the use of hearing aids. Only a small group needs body aids, binaural ear-level aids should be the routine for all the rest. In order to prevent deprivation of the acoustic sense, the whole hearing organ should be stimulated from the very beginning of the treatment with an aid in the right and in the left ear. Through routine prescription of binaural aids from the start, the psychological problem based on hearing aid use would be overcome.
