Acoustic rhinometry in pre-school children.
Acoustic rhinometry was performed in 35 normal nose-breathing children between 3 and 6 years. The average cross-sectional areas at the nasal valve, at the anterior end of the turbinates, and in the nasopharynx were 0.34 +/- 0.06 cm2, 0.35 +/- 0.08 cm2 and 1.37 +/- 0.48 cm2 respectively. The average minimal cross-sectional area was 0.29 +/- 0.06 cm2. The minimal cross-sectional area was located at the nasal valve in 14 and at the anterior end of nasal turbinates in 21 of the 35 children. As would be expected, the cross-sectional areas at different sites of the nasal cavity increased with increasing age of the children. But, whereas the minimal cross-sectional area increased by 0.024 cm2 per …
The role of acoustic rhinometry in the diagnosis of adenoidal hypertrophy in pre-school children.
Adenoidal hypertrophy is a common problem in pre-school children and diagnosis depends mostly on evaluation of clinical symptoms and signs. Investigative techniques to assess adenoidal size often do not add to this information. Recent reports have suggested a role for acoustic rhinometry in this situation. A total of 49 children consecutively referred to the Department of Otorhinolaryngology, University of Mainz, with evidence of adenoidal enlargement underwent acoustic rhinometry pre- and post-operatively and were compared to an age-matched control group from a local kindergarten school. Adenoidal size was visually estimated at surgery and questionnaires were completed by parents of sympto…
