“…There were no significant differences in the values of relative humidity and temperature between the right and the left nasal cavity in previous studies, indicating that the state of mucosal swelling alone is not responsible for air conditioning [17,18,22]. In addition, AKERLUND and BENDE [23] did not find a correlation between the nasal mucosal temperature and nasal airway resistance due to mucosal swelling.…”

“…The suction probe of the sensor allowed humidity recording at defined intranasal sites in the anterior segment in the centre of the air stream without interruption of nasal breathing. Numerous previous studies showed that the humidity sensor used is suitable for in vivo measurements in the human nasal cavity at defined detection sites [17][18][19]. Nasal resistance was measured using AAR.…”

The nasal cavity volume and the temperature of the nasal mucosa are considered to be the most important predictors of nasal conditioning. The aim of this study was to assess the relationship between the intranasal degree of water vapour saturation of inhaled air and nasal patency.Intranasal humidity values at different locations within the nasal cavity of 15 healthy subjects were compared to nasal airway resistance detected by active anterior rhinomanometry (AAR). Repeated measurements were carried out during one day to obtain varying nasal cavity volumes due to the nasal cycle. The end-inspiratory humidity data were obtained with a miniaturised capacitive humidity sensor at defined detection sites within the anterior nasal segment without interruption of nasal breathing. Measurements were carried out at four different times during one day.The degree of water vapour saturation did not correlate with the values of the AAR at any intranasal detection site and time of detection during one day.The study supports the view that there is no correlation between the degree of water vapour saturation within the anterior nasal segment and the nasal resistance during the nasal cycle over the day. Although nasal patency varies because of the nasal cycle, the changes of nasal cavity volume due to the nasal cycle do not seem to influence the degree of water vapour saturation of the inspiratory air.

“…2 Nasal septal surgery is one of the most common causes of septal perforation. 4 The symptoms such as nasal crusting, epistaxis, nasal obstruction, noisy breathing, or whistling may be associated with nasal septal perforation depending on the location and size of the perforation. 2 Surgical closure of septal perforations is a particularly challenging operation.…”

The ITCG technique provides three-layer repair of the defect under no tension in closure of small perforations located anteriorly, posterior perforations with mucosal atrophy, or previous unsuccessful surgical repair. In graft-depleted revision rhinoplasty cases with small-sized septal perforations, this technique provides a simple solution with autogenous grafts. In cases involving larger perforations, the ITCG technique can easily be combined with bipedicled flap and allows for more options to solve a challenging problem. Current data from this prospective study suggest that this surgical technique may be used in the repair of nasal septal perforation.

Heating and humidification of the respiratory air are the main functions of the nasal airways in addition to cleansing and olfaction. Optimal nasal air conditioning is mandatory for an ideal pulmonary gas exchange in order to avoid dessication and adhesion of the alveolar capillary bed. The complex three-dimensional anatomical structure of the nose makes it impossible to perform detailed in vivo studies on intranasal heating and humidification within the entire nasal airways applying various technical set-ups. The main problem of in vivo temperature and humidity measurements is a poor spatial and time resolution. Therefore, in vivo measurements are feasible to a restricted extent, only providing single temperature values as the complete nose is not entirely accessible. Therefore, data on the overall performance of the nose are only based on one single measurement within each nasal segment. In vivo measurements within the entire nose are not feasible. These serious technical issues concerning in vivo measurements led to a large number of numerical simulation projects in the last few years providing novel information about the complex functions of the nasal airways. In general, numerical simulations only calculate predictions in a computational model, e. g. realistic nose model, depending on the setting of the boundary conditions. Therefore, numerical simulations achieve only approximations of a possible real situation. The aim of this report is the synopsis of the technical expertise on the field of in vivo nasal air conditioning, the novel information of numerical simulations and the current state of knowledge on the influence of nasal and sinus surgery on nasal air conditioning.
