Chapter 4 Physiology and Pathophysiology of Nasal Breathing

The study analyzed the functional parameters of nasal breathing, linear parameters of the nasal aperture, nasal cavity and nasopharynx, volumetric parameters of the upper airways in patients with II and III skeletal class of jaw anomalies before and after orthognathic surgery. The respiratory function of the nose was assessed using a rhinomanometric complex. According to rhinoresistometry data, nasal resistance and hydraulic diameter were assessed. According to the data of acoustic rhinometry, the minimum cross-sectional area along the internal valve, the minimum cross-sectional area on the head of the inferior turbinate and nasal septum and related parameters were estimated. According to the CBCT data, the state of the nasal septum, the inferior turbinates, the nasal aperture, the state of the nasal cavity, and the linear values of the upper respiratory tract (nasopharynx) were analyzed. The patients were divided into 4 groups according to the classification of the patency of the nasal passages by

Topicality: The result of surgical treatment depends largely on the chosen method of management of the postoperative period, the main purpose of which is to reduce the effects of surgical trauma. Despite the wide variety of drugs for local and systemic use, the question of pharmacotherapy of the operated sinus remains open to this day. The main properties that a modern drug should possess are safety and high clinical efficacy. Aim: to study the clinical efficacy of topical application of a complex preparation based on a saline solution containing sodium hyaluronate and dexpanthenol in patients with chronic sinusitis after functional endoscopic sinus surgery (FESS). Materials and Methods: Clinical and laboratory studies were conducted on 47 patients with chronic rhinosinusitis who underwent surgery using the FESS technique. Patients were divided into 2 groups according to the principle of the postoperative period. Patients of research group (n=21), except for traditional therapy, was used locally NASOMER (a preparation based on a water-salt solution containing sodium hyaluronate and dexpanthenol); to the control group (n=26) patients entered, in the postoperative period received traditional therapy. Traditional therapy included a toilet of the nasal cavity, the use of short-course topical decongestants, irrigation of the nasal cavity with water-salt solutions. Criteria of clinical effectiveness: data of endoscopy of the nasal cavity, rhinomanometry, activity of the mucociliary transport system. The effectiveness of functional research methods in the postoperative period was determined on the 7th and 14th day of treatment. Results: On the 3rd day of the study, an increase in the swelling of the nasal cavity was observed in patients of both clinical groups, correlated with difficulty in nasal breathing. On the 7th day, a decrease in edema was observed in patients of both groups, but in the experimental group, the index of nasal breathing, according to rhinomanometry, was significantly (p<0.05) different from the control group, and was respectively 1.54±0.14 and 2.04±0.19 kPa/l*s. On the 14th day of the study, no significant difference was observed between these indicators. When studying the activity of the ciliated epithelium of the mucous membrane of the nasal cavity, it was proved that patients of the experimental group on day 7 after surgery showed a statistically significant difference in this indicator compared to the control group (17.8±1.0 and 22.7±2.1 min. respectively). Conclusions: The use of NASOMER after surgical intervention in patients with chronic rhinosinusitis contributes to more effective treatment compared with traditional therapy, as evidenced by the rapid recovery of the main functional parameters according to active posterior rhinomanometry and mucociliary clearance. Based on the results of the studies performed, the use of NASOMER for pharmacotherapy in the postoperative period is recommended for patients who have undergone rhinosurgical interventions with the aim of reducing the period of postoperative rehabilitation as an effective anti-inflammatory and wound-healing agent.

Minimal Invasiveness

Relevance: Modern endonasal surgery allows to remove polyps from all affected paranasal sinuses, following the principles of minimal invasiveness. Minimal traumatic of surgical intervention gives the best results, accompanied by less progression of the disease. Minimal invasiveness of surgical intervention and its obligatory combination with postoperative medical treatment are common practice in many countries. One of the drugs that actively effect the restoration of the mucous membrane of the nasal cavity and paranasal sinuses in the early postoperative period is Nazomer, which includes sodium hyaluronate and dexpanthenol in saline solution. The purpose of the study is to investigate the effectiveness of the drug Nazomer in patients with polyposis rhinosinusitis after endoscopic polyposynosotomy. Results and discussion: The main group consisted of 30 patients with polyposis rhinosinusitis, who were prescribed Nasomer in addition to standard treatment in the postoperative period. The control group included 30 patients who underwent standard treatment in the postoperative period. As criteria for clinical efficacy, data from endoscopic examination of the nasal cavity and indicators of anterior rhinomatometry, measured by the «Optimus» device, were selected. In the main group, the index of nasal breathing according to rhinomatometry was better than the results of patients in the control group on the 3rd and 5th day of the postoperative period by 26% and 24%, respectively. Conclusion: The use of the drug Nazomer in the postoperative period in patients with polyposis rhinosinusitis contributes to more active restoration of respiratory function of the nasal cavity compared with the control group, according to rhinomatometry, up to 26%. Based on the results obtained, the drug Nazomer is an effective anti-inflammatory and regenerative agent in the postoperative period in patients with polyposis rhinosinusitis.

Abstract Purpose Humans have a preference for nasal breathing during sleep. This 10-year prospective study aimed to determine if nasal symptoms can predict snoring and also if snoring can predict development of nasal symptoms. The hypothesis proposed is that nasal symptoms affect the risk of snoring 10 years later, whereas snoring does not increase the risk of developing nasal symptoms. Methods In the cohort study, Respiratory Health in Northern Europe (RHINE), a random population from Denmark, Estonia, Iceland, Norway, and Sweden, born between 1945 and 1973, was investigated by postal questionnaires in 1999–2001 (RHINE II, baseline) and in 2010–2012 (RHINE III, follow-up). The study population consisted of the participants who had answered questions on nasal symptoms such as nasal obstruction, discharge, and sneezing, and also snoring both at baseline and at follow-up (n = 10,112). Results Nasal symptoms were frequent, reported by 48% of the entire population at baseline, with snoring reported by 24%. Nasal symptoms at baseline increased the risk of snoring at follow-up (adj. OR 1.38; 95% CI 1.22–1.58) after adjusting for age, sex, BMI change between baseline and follow-up, and smoking status. Snoring at baseline was associated with an increased risk of developing nasal symptoms at follow-up (adj. OR 1.22; 95% CI 1.02–1.47). Conclusion Nasal symptoms are independent risk factors for development of snoring 10 years later, and surprisingly, snoring is a risk factor for the development of nasal symptoms.

The Impact

Objectives: This study was conducted to examine the impact of sexual activity on nasal breathing and compare such effect to that of a nasal decongestant. Methods: We evaluated nasal breathing at 5 different times: (1) before sexual activity (baseline), (2) immediately after sexual activity, (3) 30 minutes, (4) 1 hour (5), and 3 hours after sexual climax. Same measurements were taken on the second day following application of nasal decongestant spray. For evaluation of nasal breathing, we used a visual analogue scale (VAS). Additionally, we used a portable rhinometric device to measure resistance and nasal flow. Results: Nasal breathing improved significantly after sexual intercourse with climax to the same degree as after application of nasal decongestant for up to 60 minutes, as measured subjectively with the VAS (sex −3.6, P < .001; spray −3.2, P < .001). This was confirmed in the objective rhinometric data as mean nasal flow (mL/s) increased while resistance decreased immediately (flow sex +214, P < .001; flow spray +235, P < .001), 30 (flow sex +249, P < .001; flow spray +287, P < .001), and 60 minutes (flow sex +180, P < .001; flow spray +287, P < .001) post-intervention. Nasal breathing was back to the baseline level after 3 hours following sexual intercourse, while it continued to be improved for longer after application of nasal decongestant. Only participants having nasal obstruction (Nasal Obstruction Symptom Evaluation score >30) showed nasal function improvement after sex. Conclusions: Sexual intercourse with climax can improve nasal breathing to the same degree as application of nasal decongestant for up to 60 minutes in patients having nasal obstruction.

Peak Nasal Inspiratory Flow

Purpose: To investigate the influence of breathing mode and nasal patency in the dimensions of the hard palate by comparing mouth breathing (MB) and nasal breathing (NB) adults. Methods: Seventy-seven individuals, distributed into the MB group (n=38) and the NB group (n=39), of both genders and aged between 18 and 30 years old, took part in the study. The respiratory mode diagnosis was based on anamnesis, physical characteristics, and otorhinolaryngological examination. The volunteers were evaluated in terms of nasal patency, with a peak nasal inspiratory flow (PNIF) meter, and obstruction symptoms, by a Nasal Obstruction Symptom Evaluation (NOSE) scale, and had their transversal and vertical hard palate dimensions measured with a digital caliper in plaster models. Results: Comparing both groups, the MB group presented significantly higher values in the NOSE scale, lower values in the PNIF, lower values in the transversal distance of the palate in the intercanine region, and significantly higher values in the vertical distance in the regions of the first and second premolars and molars. There was a negative correlation between PNIF and NOSE, and a positive correlation between PNIF and transversal distance of the palate in the region of the first premolars. Conclusion: MB adults presented reduced nasal patency and a higher degree of nasal obstruction symptoms. The hard palate was morphologically narrower and deeper in adults with the MB mode compared to the NB mode. Moreover, it was concluded that the smaller the nasal patency, the greater the obstruction symptoms and the narrower the hard palate.
