- ItemAcesso aberto (Open Access)Avaliações objetiva e subjetiva da obstrução nasal em crianças e adolescentes com rinite alérgica(Sociedade Brasileira de Pediatria, 2012-10-01) Mendes, Aline Inês [UNIFESP]; Wandalsen, Gustavo Falbo [UNIFESP]; Solé, Dirceu [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)OBJECTIVE: To correlate objective assessment of nasal obstruction, as measured by acoustic rhinometry (volume of the first 5 cm of the nasal cavity) and active anterior rhinomanometry (total nasal airway resistance), with its subjective evaluation (obstruction scores). METHOD: Thirty patients, aged 7 to 18 years, with persistent allergic rhinitis and thirty controls were enrolled. The obstruction score was reported for the whole nasal cavity and for each nostril separately. The three variables were measured at baseline and after induction of nasal obstruction. RESULTS: There were significant and negative correlations between resistance and nasal volume in all groups and scenarios, except for the most obstructed nostril, in the control group, post-obstruction. For the whole nasal cavity, there was no significant correlation between objective and subjective variables except between score and total nasal cavity volume in the control group, post-obstruction. Regarding the most obstructed nostril, we found a significant negative correlation between score and resistance and a significant positive correlation between score and volume for the total group at baseline. There were no clear differences in the correlation coefficients found in patients and controls. The correlation coefficients did not change after induction of nasal obstruction. CONCLUSIONS: Objective assessment of nasal obstruction did not correlate significantly with subjective evaluation for the nasal cavity as a whole, but there was a correlation for unilateral assessments. There was correlation between the objective evaluations. Allergic rhinitis and acute induction of nasal obstruction did not affect the correlation between objective and subjective assessments of nasal obstruction. Addition of an objective method for evaluation of nasal obstruction could be useful in the research setting; if no such method can be used, each nostril should be evaluated separately.
- ItemAcesso aberto (Open Access)Correlação entre a resistência nasal e diferentes parâmetros da rinometria acústica em crianças e adolescentes com e sem rinite alérgica(Associação Brasileira de Otorrinolaringologia e Cirurgia Cervicofacial, 2012-12-01) Wandalsen, Gustavo Falbo [UNIFESP]; Mendes, Aline Inês [UNIFESP]; Solé, Dirceu [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Acoustic rhinometry and rhinomanometry are important tests used to assess nasal function. The degree to which the parameters of these tests are correlated is yet to be established. OBJECTIVE: This paper aimed to study the correlations between nasal resistance (NR) and acoustic rhinometry parameters in children and adolescents with allergic rhinitis and controls. METHOD: Twenty patients with allergic rhinitis and 20 controls were enrolled. NR, volumes (V4, V5, V2-5), and minimal cross-sectional areas (MC1, MC2) were measured in three moments: baseline, after induction of nasal obstruction and after topical decongestant administration. RESULTS: Patients with allergic rhinitis had significant correlation between NR and all volumes (V5: r = -0.60) and with MC2. Among controls, MC1 was the parameter with the strongest correlation with NR at baseline (r = -0.53) and after decongestant administration. In the combined analysis, V5 had the highest correlation coefficients at baseline (r = -0.53), after obstruction (r = -0.58) and after decongestant (r = -0.46). CONCLUSIONS: Our data showed that NR and acoustic rhinometry parameters have negative and significant correlations. Nasal volumes are, in general, better correlated than minimal cross-sectional areas. V5 was the parameter with the highest correlation in the rhinitis group and in the combined analysis.
- ItemAcesso aberto (Open Access)Rinolitíase como causa de fístula oronasal(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2005-02-01) Dib, Gabriel Cesar [UNIFESP]; Tangerina, Rodrigo P. [UNIFESP]; Abreu, Carlos E.c. [UNIFESP]; Santos, Rodrigo de Paula [UNIFESP]; Gregório, Luiz Carlos [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Rhinolithiasis is a disease caused by deposition of organic and inorganic compounds in the nasal cavity, leading to unilateral nasal obstruction, fetid rhinorrhea, epistaxis, and it may cause complications. The authors present a case of rhinolithiasis with oronasal fistula and literature review.
