Hyperbaric oxygen as a method of therapy of sudden sensorineural hearing loss.

Sudden hearing loss is a sensorineural hearing impairment, which develops over a period of few hours to a few days. Several theories have been proposed regarding the development of sudden sensorineural hearing loss. The incidence of sudden sensorineural hearing loss has been reported to range from 5 to 20 per 100,000 persons per year. Hearing loss is treated with drugs that provide better blood supply to the inner ear and decrease inflammation. The aim of this study is to examine the influence of hyperbaric oxygen therapy in treating sudden sensorineural hearing loss. The beneficial effects of HBO2 on sudden sensorineural hearing loss are probably achieved by an increase in the distribution of O2 dissolved per volume unit of blood circulating trough the regions affected by the lack of oxygen. Sessions were performed on 17 patients, with sudden sensorineural hearing loss that began within 10 days prior to the tests. In the hyperbaric chamber, all patients breathed 100% oxygen at 2.8 bars, for 60 minutes twice a day, either until recovered or for a maximum of 30 sessions. Of the total number of study participants, 12 were male and 5 were female, and their average age was 35.3 years (range: 18 to 68). Before the therapy, an average hearing value was obtained out of five basic frequencies. Hearing was found to be in the range of 61-93 dB in 12 patients, while 5 patients had hearing in the range of 41-60 dB. Following therapy with hyperbaric oxygen, the hearing level of 14 patients was within the range of 0-26 dB, two patients' hearing level increased to 27-40 dB, and one patient's hearing level remained in the range of 41-60 dB. The average hearing level for all patients and for all five basic frequencies was 67.8 dB before therapy, in comparison with 21.6 dB after oxygen therapy (p=0.0003). The average number of sessions in the hyperbaric chamber was 11.9 (range: 5 to 20). The therapy was taken well by all patients. The results of this study, as well as the results of similar studies performed by other authors, indicate for the necessity of performing an additional prospective, random, double-blind study of the effects of hyperbaric oxygen therapy on sudden sensorineural hearing loss, on a large number of patients.

Giant rhinophyma--a case report.

Rhinophyma is an uncommon condition that often results in both functional and cosmetic impairment. A 65-year old male with a huge rhinophyma, that had extremely grown in the last three years, is presented. The huge tumor was removed under local anaesthesia with electrosurgical knife preserving the alar cartilage. Both, the immediate and late result were satisfactory. The relevant literature is discussed.

Cardiovascular reflex testing and pupil cycle time in open-angle glaucoma.

The aim of the study is to assess the value of function tests of the autonomic nervous system in open-angle glaucoma by testing the cardiovascular reflexes and pupil cycle time. The experimental group consisted of 19 glaucoma subjects with controlled intraocular pressure. The control group consisted of 20 healthy volunteers. The Valsalva test has proven to be considerably accurate in the assertion of autonomic dysfunction (p < 0.05). Pupil cycle time was significantly prolonged (p < 0.001). These results confirm the role of autonomic dysfunction in open-angle glaucoma.

[Immunologic studies of secretory otitis].

Evaluation of total serum proteins and RIST immunoelectrophoresis of immunoglobulins IgG, IgA and IgM were carried out on a group of 35 children of both sexes suffering from secretory otitis. The transudate aspirated from the middle ear was examined only by immunoelectrophoresis. The values for albumin and gammaglobulins were decreased for all the patients. The values for RIST were significantly lower than those where an allergic cause was present. The values for immunoglobulins in transudate were also significantly lower than normal.

[Effect of radiotherapy on the function of the parotid gland].

The incidence of adverse effects on radiotherapy in head and neck cancer is quite common. Some irradiation doses affecting parotid gland have been investigated. 38 irradiated cases and 12 non-irradiated cases constituting the control group have been included in the study. Histologic examination, sialography, scintigraphy and sialometry have been performed in all cases. The impairment of parotid gland is evident in the early stage and is aggravated with time. Glandular function is not reduced significantly by irradiation doses of 2000-3000 r. A marked functional reduction has been noted with irradiation doses of 5000-6000 r., and is variable in each individual. The reduced glandular function was particularly reduced in the early postirradiation period. The subsequent functional improvement is related to the remainder of less affected parenchyma, reduced inflammatory process and rapid growth of goblet cells in the walls of the outlet system compensating mucus deficit.

[The fascia and perichondrium in reconstructive surgery of the middle ear].

Analysis of 140 patients operated on for chronic otitis media showed that the perichondrium possesses biological qualities similar to those of the fascia, although it is used less often. When using the fascia, perforations occurred in 16% of the operated patients, whereas when using the perichondrium the incidence was 20%. Improved hearing when using the perichondrium was observed in 69%, and when using fascia in 42%. Functional results with the perichondrium were much better than with the fascia.

[Snoring and obstructive sleep apnea].

Snoring and obstructive sleep apnea are similar disorders in etiology, with differences in clinical presentation and treatment. 5-20% of young and 40-50% of older population are affected by either of these disorders. Etiology of snoring should be sought in the anatomic irregularities of commencing portions of the upper respiratory and gastrointestinal tracts, obesity, alcohol abuse, use of some medications as well as in the sleep architecture disturbance. Treatment success depends on correctly established diagnosis and precise localisation of anatomic irregularity implicated in snoring. A wide array of diagnostic tests exist some of which are mandatory while the others are used on a case-by-case basis. Treatment is either conservative or surgical. The success rate is 30-90% depending on the type and the management of disorder. An algorithm for diagnosis and treatment of snoring and obstructive sleep apnea is shown at the end of the paper.
