[Epidemiology of skin tumors of the face and neck (ORL region) treated surgically from 1981 to 1990].

This paper reviews basic epidemiologic characteristics of 1549 changes located on face, neck and lips and surgically treated at the ORL Department of the General hospital in Subotica during the period 1981-1990. We analyzed the following parameters: frequency of certain diseases, their distribution according to the studied period of time, sex and age distribution, place of living, interaction between malignant and benign tumors as well as eventual influence of some meteorologic factors in regard to the previous 10-year period. It has been established that malignant tumors, precancerous and benign tumors make up 70% of surgically treated patients. There has been no statistically significant difference between sexes or according to the place of living. Most patients are in the eighth decade. It has been established that there is a slight trend of increase in regard to the number of operated patients in some studied years both in malignant and benign tumors, but there seems to be no connection between the number of surgically treated patients and analyzed meteorologic factors.

[Evaluation of the level of hearing loss based on the results of tympanometry in children under 5 years of age with eustachian tube dysfunction].

INTRODUCTION: The paper describes the correlation between pathological tympanogram findings, and the degree and type of hearing loss. We have established a possibility of indirect evaluation of hearing loss based on tympanometric curve, in children aged five or less, with tympanometry established dysfunction of Eustachian tube. Statistical methods provided a degree of certainty based on which conclusions can be made on the degree of hearing loss. MATERIAL AND METHODS: The research was done from 1986 to 1998 in an insulated chamber of the audiological laboratory of the General Hospital in Subotica. 100 children were tested, aged between 5 and 19. RESULTS: We have found that: type B tympanogram shows a statistically significant incidence in the examined group; patients with Eustachian tube dysfunction show a statistically significantly higher incidence of pathologic compared to normal audiogram, conductive hearing loss compared to other types of hearing loss, mild hearing loss compared to other types of hearing loss, horizontal audiogram form; based on performed tests, with a 95% expectancy, it can be concluded that 90% of patients whose Eustachian tube dysfunction is characterized by type B tympanogram simultaneously show (mild or medium) hearing loss, i.e. 70% of patients with type B tympanogram show a mild hearing loss, and 20% have a medium hearing loss. CONCLUSION: It is well known that the degree of hearing loss does not depend on tympanogram, but the above the research and statistical methods used indirectly lead to a conclusion that in mild dysfunction of Eustachian tube characterized by type C tympanogram the conductive hearing reduction does not exceed 25 dB, while in cases with type B tympanogram we can expect a conductive hearing loss between 20 and 40 dB, and in 20% of cases a conductive hearing loss of 40-60 dB. The results of this research show that findings of tympanometric testing can be used as a basis for hearing evaluation in children below 5 years of age with a diagnosed Eustachian tube dysfunction.

[Allergic rhinitis as a possible etiologic cause eustachian tube dysfunction].

INTRODUCTION: Allergic diseases of the upper respiratory tract are becoming one of the leading factors in the etiology of Eustachian tube dysfunctions. Eustachian tube dysfunctions are one of the three most significant etiologic factors of secretory otitis. MATERIAL AND METHODS: The most numerous group, aged 5-9 years, included 80% of subjects. Type B tympanogram was found in 173 (86.50%), and type C in 27 (13.50%) ears. Positive family anamnesis for allergic diseases was found in 26 (26%) subjects. A positive skin test for standard group in inhalatory allergen was present in 21 (21%) subjects. RESULTS AND DISCUSSION: Sex and age distribution of subjects correlate with data of other sources. A significantly higher incidence is found in the age group of 5-9 years. In presented sources the incidence of allergic diseases and Eustachian tube dysfunction is relatively wide and ranges between 20 and 50%. Results obtained by our research correlate with the mentioned values. CONCLUSION: This paper reports results of our own research of the incidence of allergic rhinitis, in cases of tympanometrically proven Eustachian tube dysfunction, in patients 5 to 19 years of age. Allergic rhinitis to inhalatory allergens was diagnosed in 21% of subjects. Based on the above mentioned we can conclude that one out of four patients aged between 5 and 19 with the diagnosed Eustachian tube dysfunction also suffers from allergic rhinitis. The consulted sources confirm that allergic rhinitis can be considered as one of the leading etiological factors of Eustachian tube dysfunction.
