Liu, X. Li, J. Guo, D. Wang, Y. Zhou, X. Gao] MRT der oberen Atemwege bei nichtschnarchenden männlichen Probanden Vergleichende Studie an Kindern und Erwachsenen Objective: The aims of the study were to clarify the characteristics of the upper airway in children and to assess the effects of age on the upper airway. Materials and methods: The study was part of a long-term observational research project on non-snoring males. The cohort of children comprised 28volunteers with an age range of 8-12years. The children group was compared to three different groups of adults: a youth group (n = 30, age range 22-29years), a middle-aged group (n = 53, age range 36-57years) and a senior group (n = 31, age range 70-78years). All children were demonstrated to be non-snorers by polysomnography (PSG). MRI scans were performed on all subjects in a state of wakefulness using a custom-made instrument. Results: In addition to the total airway volume (p = 0.000), the volume of each airway region was significantly smaller in children than in adults. Although the minimum cross-sectional area of the airway in children was usually measured in the velopharynx, it located to the nasopharynx in 7.14 % of cases. However, the nasopharynx continued to increase in size with increasing age. Conclusion: Like many other physical parameters, the upper airway is significantly smaller in children than adults. The upper airway of children might be affected by the pharyngeal lymphatic ring. An increase in size of the nasopharynx was not only an age-related change, but probably also represents an anatomic advancement in non-snoring subjects.
