“…In the present study, the nasal airflow area measured with the Glatzel mirror decreased in only one child (patient 6) after applying the nasal cleansing and massage technique. A retrospective study on 36 patients with paradoxically increased airway resistance analyzed in their previous rhinomanometry data a group of patients with vasodilation after taking vasoconstrictors 18 . No studies were found proving the reasons behind this mechanism; however, it may be related to chronic rhinitis 19 .…”

This study aimed at investigating the effects of nasal cleansing and massage maneuvers on upper airway patency in mouth-breathing children. This is a case report on eight children, aged 7 to 10 years, with a speech-language-hearing diagnosis of mouth breathing and otorhinolaryngological assessment and clinical diagnosis of rhinitis. Nasal airflow and patency were respectively assessed with the Glatzel mirror and Peak Nasal Inspiratory Flow (PNIF). Then, they were submitted to nasal cleansing and massage maneuvers with a saline solution, followed by reassessment with the Glatzel mirror and PNIF to compare results. The medians of total nasal airflow quantification were significant. Data on unilateral nasal cavity measurement indicated a sharp increase in nasal airflow in each nostril, with statistically significant differences between before and after nasal cleansing and massage maneuvers. The medians of the total PNIF were significant after the cleansing. It is concluded that the nasal airflow increased in PNIF after the cleansing maneuver.

“…Observou-se, no entanto, no presente estudo que uma única criança (PCT 6) apresentou diminuição na área da aeração nasal do espelho de Altmann, após a aplicação da técnica de limpeza e massagem nasal. Em um estudo retrospectivo, formado por 36 pacientes com resistência das vias aéreas paradoxalmente aumentadas, analisou-se nos dados da rinomanometria anterior um grupo de pacientes que apresentaram vasodilatação após o uso de vasoconstritor 18 . Não foram encontrados estudos que comprovem o porquê deste mecanismo, no entanto pode estar relacionado à presença de rinite crônica 19 .…”

RESUMO Esse estudo objetivou investigar o efeito da manobra de limpeza e massagem nasal na permeabilidade da via aérea superior de crianças com respiração oral. Trata-se de um relato de caso no qual foram selecionadas oito crianças com idade entre 7 a 10 anos apresentando diagnóstico fonoaudiológico de respiração oral, com avaliação otorrinolaringológica e diagnóstico clínico de rinites. Realizou-se as avaliações da aeração nasal e permeabilidade nasal, utilizando o espelho milimetrado de Altmann e o Peak Nasal Inspiratory Flow (PNIF), respectivamente. Em seguida, executou-se as manobras de limpeza e massagem nasal com soro fisiológico. Ao término, utilizou-se novamente o espelho de Altmann e o PNIF para comparar os resultados. Os resultados obtidos pelas medianas na quantificação da aeração nasal total foram significantes. Os dados da mensuração das cavidades nasais unilateralmente indicaram aumento acentuado na aeração nasal em cada narina, tendo diferenças estatisticamente significante quando comparados com os valores antes e depois das manobras de limpeza e massagem nasal. Os valores obtidos pelas medianas no Fluxo Nasal Máximo Inspiratório Total foram significantes após a limpeza. Concluiu-se que houve aumento da aeração nasal no fluxo nasal máximo inspiratório após manobra de limpeza.

“…DR, which is a key biomechanical parameter of the elastic strain model (2), may be calculated using 3D-CT reconstruction techniques. Therefore, using 3D-CT reconstruction techniques to measure the DR of the nasal septum at maximum deviation sites, the present study aimed to determine whether DR is associated with visual analogue scale (VAS) and nasal airway resistance (NAR) (2,6), and to evaluate the application of DR measurements in nasal septoplasty endoscopic surgery.…”

Nasal septum deviation (NSD) typically occurs following otorhinolaryngologic surgery. However, there is a lack of biomechanical parameters able to accurately evaluate the severity of NSD. The present study aimed to determine whether the deformation rate (DR) is associated with visual analogue scale (VAS) and nasal airway resistance (NAR), and to evaluate the application of DR measurements in nasal septoplasty endoscopic surgery. In the present clinical trial, a total of 30 patients with NSD were enrolled, and DRs were calculated prior to surgery by three dimensional computer tomography (3D-CT) reconstruction techniques combined with mechanical analysis. The distribution of stress lines at the nasal septum deviation site was evaluated prior to operation. Following nasal septoplasty endoscopic surgery, pre and postoperation scores for VAS and NAR were compared. The results demonstrated that DR was significantly correlated with preoperational NAR (r=0.534) and VAS scores (r=0.397). According to preoperative CT measurements of NSD, DR and biomechanical properties, selective excision was performed to remove core areas of stress. It was observed that postoperative DR, NAR and VAS scores were significantly lower (all P<0.01) than those measured preoperation. Furthermore, over a follow-up period of 3 months, 23 cases (73.1%) were cured and 7 cases (23.3%) exhibited improvements. These results indicate that preoperative measurement of septum DR by 3D-CT reconstruction techniques may be important in determining the specific surgical approach of nasal septoplasty required.
