          Abstract

          To (1) quantify mucosal cooling (ie, heat loss) spatially in the nasal passages of nasal airway obstruction (NAO) patients before and after surgery using computational fluid dynamics (CFD) and (2) correlate mucosal cooling with patient-reported symptoms, as measured by the Nasal Obstruction Symptom Evaluation (NOSE) and a visual analog scale (VAS) for sensation of nasal airflow.

          Outcomes after nasal septoplasty: results from the Nasal Obstruction Septoplasty Effectiveness (NOSE) study.

          D L Witsell, Jonas T Johnson, Michael K G Stewart … (2004)
          Our goal was to assess disease-specific quality of life outcomes after nasal septoplasty in adults with nasal obstruction. We conducted a prospective observational outcomes multicenter study with 14 sites and 16 investigators, including private practice and academic settings. Patients had had septal deviation and symptomatic nasal obstruction for at least 3 months, and medical management had failed. Patients with septal deviation completed a validated outcomes instrument (the Nasal Obstruction Septoplasty Effectiveness [NOSE] scale) before and 3 and 6 months after septoplasty, with or without partial turbinectomy. Fifty-nine patients underwent surgery; there was a significant improvement in mean NOSE score at 3 months after septoplasty (67.5 versus 23.1, P < 0.0001), and this improvement was unchanged at 6 months. Patient satisfaction was very high, and patients used significantly fewer nasal medications. In patients with septal deformity, nasal septoplasty results in significant improvement in disease-specific quality of life, high patient satisfaction, and decreased medication use.

            Correlation between subjective and objective evaluation of the nasal airway. A systematic review of the highest level of evidence.

            R. Andre, H D Vuyk, A. Ahmed … (2009)
            There is no consensus about the value of objective measurements of nasal patency. To assess the correlation between the subjective sense of nasal patency and the outcomes found with rhinomanometry and acoustic rhinometry. Structured literature search. SEARCH STRATEGY AND EVALUATION METHOD: Review of English-language articles in which correlations were sought between subjective nasal patency symptoms and objective scores as found with rhinomanometry [nasal airway resistance (NAR)] and acoustic rhinometry [minimal cross-sectional area (MCA)]. Correlations were related to unilateral or combined assessment of nasal passages and to symptomatic nasal obstruction or unobstructed nasal breathing. Sixteen studies with a level of evidence II-a or II-b fit the inclusion criteria and were further analysed. Almost every possible combination of correlations or lack thereof in relation to the variables included was found. However, when obstructive symptoms were present, a correlation between the patency symptoms with nasal airway resistance and minimal cross-sectional area was found more often than in the absence of symptoms. In cases of bilateral assessment a correlation was found almost as often as it was not between patency symptoms and total nasal airway resistance or combined minimal cross-sectional areas, while in the limited amount of studies in which unilateral assessment was done a correlation was found each time between patency symptoms and nasal airway resistance. The correlation between the outcomes found with rhinomanometry and acoustic rhinometry and an individual's subjective sensation of nasal patency remains uncertain. Based on this review, it seems that the chance of a correlation is greater when each nasal passage is assessed individually and when obstructive symptoms are present. There still seems to be only a limited argument for the use of rhinomanometry or acoustic rhinometry in routine rhinologic practice or for quantifying surgical results.

              Nasal mucosal temperature during respiration.

              R Leiacker, G Rettinger, Matthew Lindemann … (2002)
              One of the most important functions of the nose is heating the inspiratory air. The aim of the present study was to measure nasal mucosal temperature at defined intranasal sites during respiration, without interruption of nasal breathing. A total of 15 healthy volunteers was included in the study. A miniaturized thermocouple was used for continuous detection of the septal mucosal temperature in the nasal vestibule, the nasal valve area, the anterior turbinate area and the nasopharynx during respiration. The highest temperature values were measured at the end of expiration, the lowest values at the end of inspiration with a statistically significant difference (P < 0.005). Mean mucosal temperature ranged from 30.2 +/- 1.7 degrees C to 34.4 +/- 1.1 degrees C. Statistically there were significant differences between the detection sites during inspiration and expiration (P < 0.05). In our study, the temperature values of the nasal mucosa depend on the intranasal detection site and the respiratory cycle. We therefore conclude that whenever data of nasal mucosal temperature are published, it is absolutely essential to describe the precise site of detection and to give information about the time of detection in the respiratory cycle.
