- ItemSomente MetadadadosAcoustic rhinometry in nasal provocation tests in children and adolescents(Hindawi Ltd, 2016) Wandalsen, G. F. [UNIFESP]; Mendes, A. L. [UNIFESP]; Matsumoto, F. [UNIFESP]; Sole, D. [UNIFESP]Objectives: To standardize acoustic rhinometry (AR) in nasal provocation tests (NPTs) with histamine in children and adolescents. Patients and Methods: We performed a cross-sectional validation to compare AR with anterior active rhinomanometry (AAR) during histamine NPT in 20 children and adolescents with persistent allergic rhinitis and 20 controls. Changes in total nasal resistance (AAR) were compared with changes in nasal volume in the first 5 cm (V5). Results: Compared with controls, patients with rhinitis had significantly higher mean total nasal resistance (0.34 Pa/cm(3)/s vs 0.21 Pa/cm(3)/s
- ItemSomente MetadadadosAlterações Nasais Funcionais E Queixas De Sono Em Pacientes Referenciados Para Rinoplastia Estética(Universidade Federal de São Paulo (UNIFESP), 2018-06-28) Fonseca, Barbara Ribeiro De Belmont [UNIFESP]; Haddad, Fernanda Louise Martinho [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Introduction: The Number Of Aesthetic Rhinoplasty Has Been Increasing, And Many Patients Undergoing Such Interventions Have Functional Abnormalities And Nasal Symptoms That Are Commonly Underestimated. On The Other Hand, Nasal Changes Are Known To Be Related To Sleep-Disordered Breathing, Which May Lead To Sleep Fragmentation And Impairment Of Sleep Quality. Although Studies Suggest That Rhinoplasty Can Improve Obstructive Sleep Apnea, In Selected Patients, Especially In Mild Cases, There Is A Lack Of Studies That Have Assessed Sleep Quality In Patients Seeking This Procedure With Aesthetic Primary Purpose, As Well As If There Is Interaction Between Sleep Quality And Symptoms And Findings Of Clinical Examination And Acoustic Rhinometry. Objective: To Evaluate The Sleep Quality Of Patients Referred For Aesthetic Rhinoplasty And To Compare The Functional Nasal Findings Between Patients With Good And Poor Sleep Quality. Methods: Observational And Transversal Study, Including 27 Patients Referred For Rhinoplasty
- ItemSomente MetadadadosAvaliação da fossa olfatória e da artéria etmoidal anterior pela tomografia computadorizada no plano coronal(Universidade Federal de São Paulo (UNIFESP), 2007) Souza, Soraia Ale [UNIFESP]; Ajzen, Sergio Aron [UNIFESP]Objetivos: avaliar a profundidade das fossas olfatorias, segundo a classificacao de Keros; determinar a frequencia de assimetria na altura e na inclinacao lateral da lamela lateral da lamina crivosa entre os lados do mesmo individuo; identificar os reparos anatomicos que caracterizam o trajeto da arteria etmoidal anterior (AEA) na parede medial da orbita e na parede lateral da fossa olfatoria; verificar a correlacao entre a presenca de pneumatizacao supra-orbitaria e o trajeto do canal da AEA (canal etmoidal anterior). Metodos: analise retrospectiva de 200 tomografias computadorizadas dos seios da face no plano coronal, realizadas de agosto a dezembro de 2006. Foram feitas medidas da profundidade da fossa olfatoria e determinadas as alteracoes de simetria do teto dos seios etmoidais quanto a altura e a inclinacao lateral das lamelas laterais da lamina crivosa. Verificou-se a frequencia de identificacao dos reparos anatomicos para a localizacao da AEA, na parede medial da orbita (forame etmoidal anterior) e do sulco etmoidal anterior na parede lateral da fossa olfatoria. Foi correlacionada a presenca de pneumatizacao supra-orbitaria com o trajeto do canal da AEA. Resultados: o tipo de Keros mais encontrado foi o tipo 11 (73 por cento), seguido do tipo I (26,3 por cento) e do tipo 111 (0,5 por cento). Em 12 por cento (24 exames) havia assimetria entre os lados quanto a altura do teto do seio etmoidal e em 48,5 por cento (97 exames) observou-se assimetria do contorno do teto, com inclinacao lateral da lamela lateral da lamina crivosa de um dos lados. Pneumatizacao supra-orbitaria foi identificada em 35 por cento (70 exames). O canal da AEA foi caracterizado em 40,5 por cento (81 exames). O sulco etmoidal anterior foi visualizado em 98 por cento (196 dos exames) e o forame etmoidal anterior foi identificado em todos os exames (100 por cento). Houve diferenca estatisticamente significante entre a presenca de pneumatizacao supra-orbitaria e a visualizacao do canal da AEA (p<0,001). Conclusao: Em relacao a profundidade da fossa olfatoria, o tipo 11 de Keros foi o mais frequente. Verificou-se assimetria do teto do seio etmoidal, na maioria dos casos relacionada com a inclinacao lateral da lamela lateral da lamina crivosa. Para estudo do trajeto da AEA, a identificacao do forame etmoidal anterior e o sulco etmoidal anterior foram referencias anatomicas confiaveis, presentes em quase 100 por cento dos exames avaliados. Notou-se que a posicao da AEA foi variavel e que na presenca de pneumatizacao supra-orbitaria, o canal da arteria foi observado abaixo da base do cranio em todos os exames, estando mais vulneravel a lesoes
- ItemSomente MetadadadosAvaliação do espaço aéreo anterior da cavidade nasal e qualidade de vida em crianças respiradores bucais submetidos à expansão rápida da maxila(Universidade Federal de São Paulo (UNIFESP), 2020-05-28) Nagai, Lucia Hatsue Yamamoto [UNIFESP]; Cappellette Junior, Mario [UNIFESP]; Universidade Federal de São PauloIntroduction: The anterior portion of the nasal cavity includes the critical region of maximal resistance to airflow that even small changes in its geometry can have a significant impact on nasal airflow. Objectives: to assess the effects of rapid maxillary expansion (RME) on the anterior skeletal and soft tissue structures of the nasal cavity in mouth-breathing children and correlated these findings with the patient’s quality of life. Methods: 35 mouth-breathing patients (mean age 10.7±2.0 years) submitted to RME were evaluated by means of computed tomography at preRME and 4-5 months thereafter. Subjective symptoms were assessed by using a validated quality of life questionnaire answered by patients and patients’ parents/legal guardians. Results: The total anterior nasal volume increased by 20.47% on average during the overall observation period. The skeletal and soft tissue volumes increased by 26.5% and 17.6% respectively, and a cross-sectional area increased by 19.96% on average. Different combinations of angles were found, however, more significant increases occurred when the angular value of one side was much smaller than opposite side. There was a statistically significant reduction in the mean scores of the quality of life scale, indicating a significant improvement in quality of life between T1 and T2. Conclusions: In the short term, RME promote a significant increase in the anterior nasal volume, with a higher proportion within the skeletal boundaries. This, associated with an increased minimum cross-sectional area, may have contributed to respiratory improvement. In addition, different combinations of nasal valve angles suggest that RME can influence the position of the septum.
- ItemAcesso aberto (Open Access)Eficácia e segurança da implantação de hipotermia cerebral exclusiva por meio do uso de cateter nasofaríngeo em seres humanos para o tratamento de traumatismo cranioencefálico grave - estudo de fase I(Universidade Federal de São Paulo (UNIFESP), 2019-11-28) Ferreira, Raphael Einsfeld Simoes [UNIFESP]; Centeno, Ricardo Silva [UNIFESP]; Paiva, Bernardo Lembo Conde de [UNIFESP]; http://lattes.cnpq.br/2407213200021772; http://lattes.cnpq.br/9709796351055284; http://lattes.cnpq.br/7930858019576181; Universidade Federal de São Paulo (UNIFESP)Objective: The objective was to determine whether a novel nasopharyngeal catheter could be used, as a new strategy, to cool the human brain (reduction of at least 2 °C) after traumatic brain injury, and the secondary objective was to assess the local and systemic effects of this therapeutic strategy. Methods: This was a non-randomized, interventional clinical trial that involved five patients with severe traumatic brain injury. The intervention consisted of inducing and maintaining selective brain cooling for 24h by positioning a catheter in the nasopharynx and circulating cold water inside the catheter in a closed loop arrangement. Core temperature was maintained greater than 35 °C using counter-warming strategies. Results: In all study participants, a brain temperature reduction of ≥ 2 °C was achieved. The mean brain temperature reduction from baseline was 2.5 ± 0.9°C (p = .04, 95% confidence interval). The mean systemic temperature was 37.3 ± 1.1 °C at baseline and 36.0 ± 0.8 °C during the intervention. The mean difference between the brain temperature and the systemic temperature during intervention was -1.2 ± 0.8 °C (p = .04). The intervention was well tolerated with no significant changes observed in the hemodynamic parameters. No relevant variations in intracranial pressure and transcranial Doppler were observed. The laboratory results underwent no major changes, aside from the K+ levels and blood counts. The K+ levels significantly varied (p = .04); however, the variation was within the normal range. Only one patient experienced an event of mild localized and superficial nasal discoloration, which was re-evaluated on the seventh day and indicated complete recovery. Conclusion: The results suggest that our non-invasive method for selective brain cooling, using a novel nasopharyngeal catheter, was effective and safe for use in humans.
