“…This underlines the importance of allergy treatment pre-and post-operatively to nasal surgery with a specific focus on nasal mucosa. Pre-operatively, patients with sleep apnea had smaller posterior MCA at the narrow side compared to patients without sleep apnea, which is supported by similar findings in Moxness` study [30]. This should underline the importance of paying attention to possible coinciding factors in patients with nasal obstruction.…”

“…Surprisingly, MCA and NCV in the posterior part of the nose were larger in our patient groups, except for the NCV3-5.2 and NCV0-5.2 in the septoplasty group which still remained smaller after surgery [29,30]. The reason for the post-operative differences may be due to anatomical features.…”

“…The measurement of peak nasal inspiratory flow (PNIF) is a validated technique that has been shown to be valuable as an objective assessment of nasal patency (4) . It has been used to analyse nasal airflow in respiratory diseases as well as to evaluate results of clinical or surgical treatments (5,6) . However, this method has limitations because it is dependent on lung function, body position, and the cooperation of the individual tested (7,8) .…”

Background:The nose is a dynamic organ and is the first point of contact between inhaled air and mucosal surfaces. Within the nasal cavity, there are changes of air flow and pressure occurring during the respiratory cycle, as well as exchanges of heat and humidity, and important immune responses to inhaled antigens and allergens.Methodology: This review is a summary for rhinologists covering what is known about airflow within the nose and sinuses and the impact of pathology and treatments on the physical environment of the nasal cavity. The review will concentrate largely on the significant contribution that computational fluid dynamics has had on this field. Results:The complex anatomical structure of the nasal cavity provides an aerodynamic environment that guides the airflow throughout the nasal cavities. However, anatomical or inflammatory changes can modify the air flow, heat and humidity exchanges, with negative consequences on nasal physiology. Restoration of normal airflow is a key goal to achieve success in the treatment of nasal diseases. Conclusions:Computational fluid dynamics is a method of analysis originating from engineering which has been adapted for rhinology. Although still an expensive and laborious technique, it may become a viable diagnostic tool in the future for studying nasal physiology.

Objectives Nasal peak inspiratory flow (NPIF) is a practical and affordable tool that measures maximum inspiratory flow rate through both nostrils. Although NPIF values for healthy controls and patients appear to differ considerably, a generally expected value for populations with and without nasal obstruction has yet to be established. The aim of this systematic review and meta‐analysis was to determine the mean NPIF value in populations with and without nasal obstruction. Methods Medline (1946–) and Embase (1947–) were searched until July 1, 2017. A search strategy was used to identify studies that reported NPIF values for defined healthy or disease states. All studies providing original data were included. The study population was defined as having either normal nasal breathing or nasal obstruction. A meta‐analysis of the mean data was presented in forest plots, and data were presented as mean (95% confidence interval [CI]). Results The search yielded 1,526 studies, of which 29 were included. The included studies involved 1,634 subjects with normal nasal breathing and 817 subjects with nasal obstruction. The mean NPIF value for populations with normal nasal breathing was 138.4 (95% CI: 127.9‐148.8) L/min. The mean value for populations with nasal obstruction was 97.5 (95% CI: 86.1‐108.8) L/min. Conclusions Current evidence confirms a difference between mean NPIF values of populations with and without nasal obstruction. The mean value of subjects with no nasal obstruction is 138.4 L/min, and the mean value of nasally obstructed populations is 97.5 L/min. Prospective studies adopting a standardized procedure are required to further assess normative NPIF values. Laryngoscope, 131:260–267, 2021

Abstract: OSA patients have a lower minimum cross-sectional area, nasal cavity volume and peak inspiratory flow compared to controls. Our study supports the view that changes in the nasal cavity may contribute to development of OSA.
