ARCH. OTOLARYNGOL. HEAD NECK SURG. (1992) 118/Z (149-152) This study was undertaken to evaluate the effect of a new method of autoinflation as an alternative treatment of secretory otitis media. Up to 80% of all children experience one or more episodes of eustachian tube dysfunction and secretory otitis media before school age. Common treatment of this condition is insertion of a ventilation tube in the tympanic membrane. Because of the very high incidence of secretory otitis media in childhood, insertion of ventilation tubes is the most frequently performed operation under general anesthesia in children. In addition to possible anesthetic complications, insertion of ventilation tubes may be associated with purulent suppuration, pathologic findings in the eardrum, and hearing impairment. One hundred children were consecutively randomized to undergo either autoinflation, using a new device, or placed in a control group. The children were between 3 and 10 years of age and were entered into the study after having had secretory otitis media for at least 3 months, as verified by tympanometric findings. Tympanometry was repeated at 2 weeks and at 1, 2, and 3 months after the children were entered into the study. After 2 weeks of autoinflation, the tympanometric conditions were improved in 64% of ears, unchanged in 34%, and deteriorated in the remaining 2%. In the control group, tympanometric findings were improved in 15% of ears, unchanged in 71%. and deteriorated in the remaining 14%.

AUDIOLOGY (1992) 31/Z (112-120) For hearing-impaired children, the main problem in the classroom is the signal-to-noise ratio. To improve the signal-to-noise ratio, several class systems have been developed, three of which have been investigated in this study. The systems are shown to be equivalent in a situation without a channel for pupil response. Application of such pupil response channels will decrease the improvement in signal-to-noise ratio brought about by the class system. It is argued that the choice among several combinations of class system and pupil response channel is governed by the primary goal of education and how this goal is to be achieved.

BR.J. AUDIOL. (1992) 26/2 (109-114) The use of molecular techniques in respect of the rare X-linked non-syndromic form of genetic deafness demonstrates that this is a genetically heterogeneous disorder. With evidence for at least two separate gene loci on the X chromosome. Audiological heterogeneity in this condition is emphasized by the observation of both mixed deafness and sensorineural deafness in pedigrees showing evidence for linkage to Xq13-q21. The importance and shortcomings of the audiogram in assessing females who are known gene carriers is discussed. The effects of bearing loss and age of intervention children Ramkalawan
