“…The difference between average CSA1 values was never beyond 10%, when comparing our data set to that of various authors 18,19,[23][24][25] , which ranged between 0.52cm 2 and 0.59cm 2 , thus validating the results published in this paper. The papers cited above are quite recent, and two used the same equipment employed in our study.…”

“…Normal cross-sectional area values have been reported by many authors [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] , whose findings are summarized on Chart 1. Nonetheless, due to factors such as ethnic, weather, and laboratory-related differences, local reference values must be determined, as stressed by Hilberg and Pedersen 7 and Roithman 26 more recently.…”

A rinometria acústica tem sido utilizada como teste específico da permeabilidade nasal. OBJETIVO: O propósito do presente estudo foi determinar valores de referência de áreas de secção transversa da cavidade nasal de adultos sadios pela técnica rinométrica. DESENHO: Estudo clínico prospectivo. CASUÍSTICA E MÉTODO: Trinta voluntários sem evidências de obstrução nasal com idade entre 18 e 30 anos (14 homens e 16 mulheres) foram avaliados antes e após a aplicação tópica de vasoconstritor nasal. As áreas de secção transversa foram medidas nos três entalhes do rinograma correspondentes à válvula nasal (AST1), região anterior (AST2) e região posterior (AST3) das conchas nasais inferior e média. RESULTADOS: Os valores médios (±DP) das áreas aferidas em 60 cavidades antes da vasoconstrição nasal foram os seguintes: 0,54±0,13cm2 (AST1), 0,98±0,31cm2 (AST2) e 1,42±0,44cm2 (AST3). Após a vasoconstrição, os valores médios dos três segmentos analisados foram significantemente maiores (p<0,05). Não foram constatadas diferenças significantes entre os sexos. CONCLUSÃO: As áreas seccionais nasais de adultos obtidas para adultos podem ser usadas para fins de controle no estudo de pacientes com obstrução nasal, em complementação aos volumes nasais relatados anteriormente por nosso grupo.

“…SR2000 equipment, Rhinometrics, (Denmark) with nasal adaptors were used to analyze the results. 18 For ARM, the minimal cross-sectional area (MCA) 1 (corresponding to nasal valve) and 2 (corresponding to inferior turbinate) were examined for each nostril. In RMM, the resistance during both inspiration and expiration was verified for each nostril.…”

OBJECTIVE: To assess the effects of rapid maxillary expansion on facial morphology and on nasal cavity dimensions of mouth breathing children by acoustic rhinometry and computed rhinomanometry. METHODS: Cohort; 29 mouth breathing children with posterior crossbite were evaluated. Orthodontic and otorhinolaryngologic documentation were performed at three different times, i.e., before expansion, immediately after and 90 days following expansion. RESULTS: The expansion was accompanied by an increase of the maxillary and nasal bone transversal width. However, there were no significant differences in relation to mucosal area of the nose. Acoustic rhinometry showed no difference in the minimal cross-sectional area at the level of the valve and inferior turbinate between the periods analyzed, although rhinomanometry showed a statistically significant reduction in nasal resistance right after expansion, but were similar to pre-treatment values 90 days after expansion. CONCLUSION: The maxillary expansion increased the maxilla and nasal bony area, but was inefficient to increase the nasal mucosal area, and may lessen the nasal resistance, although there was no difference in nasal geometry. Significance: Nasal bony expansion is followed by a mucosal compensation.

“…3 The technique is used to check nasal geometry, to identify altered patency, and to monitor the results of surgical procedures on nasal and nasopharyngeal airways. [1][2][3][4][5][6][7] Hilberg e Pedersen 8 underlined the importance of creating cross-sectional and volume reference values in their recommendations to the European Rhinological Society on the use of acoustic rhinometry to analyze naso-respiratory function. Nasal volume values based on acoustic rhinometry in normal subjects have been published by various authors using different equipment to analyze nasal segments.…”

Acoust ic rhinometry allows an objective and non-invasive assessment of nasal geometry. Aim: The present study aimed at determining the volumes of specific segments of the nasal cavity in healthy adults including the nasopharynx, using acoustic rhinometry. Study design: A clinical prospective analysis. Cases and Method: Thirty volunteers with no evidence of nasal obstruction, aged 18 to 30 years (14 males and 16 females) were analyzed. Volumes were measured at the nasal valve region (V 1 ), the turbinates (V 2 ), and the nasopharynx (V 3 ), before and after application of a topical nasal vasoconstrictor. Results: The mean volumes measured in 60 cavities before nasal decongestion, were: 1.81±0.35cm 3 (V 1 ), 4.02±1.41cm 3 (V 2 ), and 17.52±4.44cm 3 (V 3 ) for males, and 1.58±0.25cm 3 (V 1 ), 3.94±1.03cm 3 (V 2 ), and 17.80±2.73cm 3 (V 3 ) for females. Gender differences were only significant in V 1 (p<0.05). After nasal decongestion, the volumes of all the analyzed segments were significantly larger (p<0.05), and the gender differences were significant for V 1 and V 2 . Conclusion: Volumes of the three segments in adults with no evidence of nasal obstruction may be used as reference values for other studies.
