“…Recent studies have shown that tonsillotomy has the same beneficial long-term effect on other obstructive symptoms such as sleep apnoea and snoring as tonsillectomy, while causing lower primary morbidity and less pain (21,22). In a previous publication the present authors have shown that oral-motor function is equally improved after both tonsillectomy and tonsillotomy (23). The aim of the present study is to perceptually and acoustically evaluate vocal function in preschool children with hypertrophic adenotonsillar tissue in comparison to healthy children.…”

“…The frequency of the third formant has been shown to be influenced by the tip of the tongue (25) In a previous study, oral motor function was investigated in the same children as in the present (23) . A protruding positioning of the tip of the tongue was found more often in the children with tonsillar hypertrophy than in corresponding control group.…”

Objective: To evaluate outcome of two types of tonsil surgery (tonsillectomy+adenoidectomy or tonsillotomy +adenoidectomy) on vocal function perceptually and acoustically.Study Design: Sixty-seven children, aged 50-65 months, on waiting list for tonsil surgery were randomized to tonsillectomy (n=33) or tonsillotomy (n=34). Fifty-seven age and gender matched healthy pre-school children were controls. Twenty-eight of them, aged 48-59 months, served as control group before surgery, and 29, aged 60-71 months, after surgery Methods: Before surgery and six months postoperatively, the children were recorded producing three sustained vowels (/, , ) and 14 words. The control groups were recorded only once.Three trained speech and language pathologists performed the perceptual analysis using Visual Analogue Scales (VAS) for eight voice quality parameters. Acoustic analysis from sustained vowels included average fundamental frequency, jitter percent, shimmer percent, noise-to-harmonic ratio and the centre frequencies of formants 1-3Results: Before surgery the children were rated to have more hyponasality and compressed/throaty voice (p<0,05) and lower mean pitch (p<0,01) in comparison to the control group. They also had higher perturbation measures and lower frequencies of the second and third formant. After surgery there were no differences perceptually. Perturbation measures decreased but were still higher compared to the control group's, p<0, 05.Differences in formant frequencies for // and / remained. No differences were found between the two surgical methods.Conclusion: Voice quality is affected perceptually and acoustically by adenotonsillar hypertrophy. After surgery the voice is perceptually normalized but acoustic differences remain. Outcome was equal for both surgical methods.

“…This difference is also reflected in the results of the perceptual analysis made by the experienced listeners who judged the /s/-sounds of the children in the study groups to be significantly less distinct than those of the controls. These results can be explained by the oral motor problems that children with tonsillar hypertrophy experience (Lundeborg, McAllister, Graf et al, 2009). The production of the /s/-sound, with its demands on precise placements of the articulators, especially the tongue seems to be vulnerable to the structural alteration of the oral cavity that hypertropic tonsils cause.…”

“…In a previous investigation on the same material we found that oral motor function regarding non speech activities was hampered in children with tonsillar hypertrophy and normalized after surgery (Lundeborg, McAllister, Graf, Ericsson, and Hultcrantz, 2009). The study also revealed some minor sex differences with the boys having somewhat larger problems before surgery than girls.…”

Tonsillar hypertrophy is common in young children and affects several aspects of the speech such as distortions of the dento-alveolar consonants. The study objective was to assess sarticulation, perceptually and acoustically in children with tonsillar hypertrophy and compare effects of two types of surgery, total tonsillectomy and tonsillotomy. Sixty-seven children, 50-65 months, on waiting list for surgery, were randomized to tonsillectomy or tonsillotomy. The speech material was collected pre-operatively and six months post-operatively. Two groups of age-matched children were controls. /S/-articulation was affected acoustically with lower spectral peak locations and perceptually with less distinct /s/-production before surgery, in comparison to controls. After surgery /s/-articulation was normalized perceptually, but acoustic differences still remained. No significant differences between surgical methods were found..

Objectives: To study the development of craniofacial and dental-arch morphology in children with sleep disordered breathing in relation to adeno-tonsillar surgery. Subjects and method:From a community based cohort of 644 children, 393 answered questionnaires at age 4, 6 and 12 years. Out of this group, twenty-five children who were snoring regularly at age 4 could be followed up to age 12 together with 24 controls not snoring at age 4, 6 and 12 years. Study casts were obtained from cases and controls and lateral cephalograms from the cases. Analysis regarding facial features and dento-alveolar development was performed.Results: Children snoring regularly at age 4 showed reduced transversal width of the maxilla and more frequently had anterior open bite and lateral cross-bite than the controls. These conditions persisted for most cases at age six, by which time 18/25 had been operated for snoring. In most of the cases, surgery cured the snoring temporarily, but their width of the maxilla was still smaller by age 12-even when nasal breathing was attained. At age 12, the frequency of lateral cross-bite was much reduced and anterior open bite was resolved, both in cases and controls. The children who snored regularly at age 12 showed a long face anatomy and were oral breathers; this applied even to those who were operated. The seven cases who were not operated and the five who were still snoring in spite of surgery at age 12, did not have reduced maxillary width as compared to the controls. Conclusion:Dento-facial development in snoring children is not changed by adenotonsillar surgery regardless of symptom relief.
