The aim of this study was to determine the level of motor development of children with visual impairment and comparison with peers of typical development. The research sample consisted of a total of 135 children with visual impairment and children with typical development, 7-10 years old, of both sexes. The Bruininks-Oseretsky Test of Motor Proficiency, 2nd edition was used to estimate motor development. The methods of descriptive statistics, as well as the T-test of independent samples, and the Hi square test were used in statistical processing of the obtained data. The results of the study had shown that the level of motor development of the subjects with visual impairment was below and well below the average for their age. Typical development subjects are mostly within the average norms

Speech detection threshold (SDT) depends on audibility alone, whereas speech recognition threshold (SRT) requires the stimuli to be heard and identified. The aim of the study was to determine the difference between SDT and SRT, and to analyze the correlation between pure tone thresholds and speech thresholds. Difference between SDT and SRT was ≤ 12 dB in majority of cases (p = .018). SDT was strongly correlated with the best pure tone threshold. Pearson correlation coefficient was the highest in "Inverted U" shape (r = .99). There was strong correlation between SRT and PTA (500-2000), PTA (500-4000), and PTA (500-1000), especially in Rising configuration (r = .997, r = .992 r = .989, respectively), as well as, between SRT and frequency of 1000 Hz (r = .989). SRT is in the highest correlation with PTA (500, 1000, 2000 Hz) and with the hearing threshold at frequency of 1000 Hz.

The aim of the study was to compare pre-treatment and post-treatment pure tone thresholds and tympanometric findings in preschool children with adenoid hypertrophy and hearing loss. This retrospective study included 63 children, 40 males (63.5%) and 23 females (36.5%), aged 4 to 6 years (mean age of 5.5±0.6 years). A total of 21 children (33.3%) had tympanostomy tube placement in addition to adenoidectomy or adenotonsillectomy. All children had mild conductive hearing loss. Pure tone average (PTA) was lower after adenoidectomy and adenotonsillectomy (p<0.0001). Type B tympanogram was predominant before treatment (62.7%), and type A tympanogram after treatment (81%). Preoperative mean PTA in children with adenoidectomy was 28 dB HL and in children with adenotonsillectomy was 27 dB HL. In both subgroups postoperative mean PTA was 16 dB HL. In children with adenoid hypertrophy and conductive hearing loss, hearing thresholds after adenoidectomy or adenotonsillectomy are significantly lower than preoperative hearing thresholds.
