“…In all chronic rhinosinusitis patients, nasal obstruction was examined (prior to FESS) by active anterior rhinomanometry with a nasal nozzle at air pressure 100 Pa (MPR-3100; Nihon Kohden, Tokyo, Japan), according to the manufacturer's instructions 15 …”

“…Inspiratory nasal airway resistance at 100 Pa was determined. 7 When the nasal airway resistance was unmeasurable due to complete nasal obstruction, it was defined as 5 Pa/cm 3 /s. Similarly, preoperative and 3-month postoperative olfactory tests (T&T olfactory test) were performed in 47 patients with subjective moderate-to-severe hyposmia or anosmia.…”

Objective:In 2013, the Japanese Rhinologic Society proposed a simple classification for endoscopic sinus surgery (ESS). This classification consists of five procedures (type I, fenestration of the ostiomeatal complex, with uncinectomy and widening of the natural ostium; type II, single-sinus procedure, with manipulating the inside of the sinus; type III, polysinus procedure; type IV, pansinus procedure; type V, extended procedure beyond the sinus wall). The clinical relevance of this classification in chronic rhinosinusitis (CRS) and paranasal sinus cyst was evaluated.Study Design:A retrospective validation study.Methods:A total of 122 patients (195 sinuses) who underwent ESS in Okayama University Hospital in 2012 were enrolled. The relationships between the ESS classification and the clinical course, including the operation time, bleeding amounts during surgery and postoperative changes of olfaction, the computed tomography (CT) score, and nasal airway resistance were analyzed.Results:A total of 195 ESS procedures were classified into type I (n = 3), type II (n = 17), type III (n = 91), type IV (n = 82), and type V (n = 2). The major phenotypes of type II, III, and IV ESS were paranasal sinus cyst (68%), CRS without nasal polyps (77%), and CRS with nasal polyps (55%), respectively, and the difference was significant. The degree of ESS based on this classification was positively and significantly correlated with the operation time and bleeding amounts. As a whole, olfaction, CT score, and nasal airway resistance were significantly improved after surgery. The degree of improvement was similar between type III and type IV ESS.Conclusion:This simple classification for ESS reflected the perioperative burden of the disease.

“…Briefly, left and right unilateral measurements were performed, and all nasal resistance measurements were calculated according to Ohm’s law. Total inspiratory nasal resistance at negative 100 Pa was calculated [8]. These procedures were repeated three times, and mean value of those was adopted as nasal resistance.…”

The effects of heated humidification to nasopharynx on nasal resistance and breathing pattern

et al. 2019

BackgroundMouth breathing could induce not only dry throat and eventually upper respiratory tract infection, but also snoring and obstructive sleep apnea, while nasal breathing is protective against those problems. Thus, one may want to explore an approach to modify habitual mouth breathing as preferable to nasal breathing. The aim of this study was to investigate the physiological effects of our newly developed mask on facilitation of nasal breathing.MethodsThirty seven healthy male volunteers were enrolled in a double blind, randomized, placebo-controlled crossover trial. Participants wore a newly developed heated humidification mask or non-heated-humidification mask (placebo) for 10-min each. Subjective feelings including dry nose, dry throat, nasal obstruction, ease to breathe, relaxation, calmness, and good feeling were asked before and after wearing each mask. In addition, the effects of masks on nasal resistance, breathing pattern, and heart rate variability were assessed.ResultsCompared with the placebo mask, the heated humidification mask improved all components of subjective feelings except for ease to breathe; moreover, decreased nasal resistance and respiratory frequency accompanied a simultaneous increase in a surrogate maker for tidal volume. However, use of the heated humidification mask did not affect heart rate variabilityConclusionAdding heated humidification to the nasopharynx could modulate breathing patterns with improvement of subjective experience and objective nasal resistance.
