Temperature-controlled radiofrequency treatment of the nasal valve in nasal airway obstruction patients with septal deviation.

Nasal valve treatment with TCRF results in NAO symptom improvement in the presence of septal deviation. Severe septal deviation does not impact the beneficial effect of TCRF nasal valve treatment. Symptoms improve with TCRF nasal valve treatment even if septal deviations involve the nasal valve.

Twelve-month outcomes following temperature-controlled radiofrequency treatment of the septal swell body for nasal airway obstruction.

Improved nasal airway obstruction (NAO) symptoms were reported at 3 months following temperature-controlled radiofrequency (TCRF) treatment of the septal swell body (SSB). This report provides results from assessments of the long-term safety and efficacy of TCRF treatment of SSB hypertrophy to treat NAO through 12 months posttreatment. This prospective, multicenter, long-term, open-label study was conducted in nine centers within the United States and included patients with severe/extreme NAO attributed to SSB hypertrophy. Outcome measures included assessments of Nasal Obstruction Symptom Evaluation Score (NOSE), Numeric Rating Scale (NRS) ease-of-breathing, patient satisfaction, and adverse events at 6 and 12 months. Of the 70 patients treated, 65 and 62 patients completed the 6- and 12-month follow-up assessments. Compared to baseline, there was a 67.5% decrease in adjusted mean NOSE scores at 6 months (mean change -49.6, 95% confidence interval [CI] -54.8 to -44.4; p<0.001) and a 65.4% decrease at 12 months (mean change -48.1, 95% CI -53.7 to -42.5); p<0.001), which is consistent with previously published 3-month results. A 62.0% and 62.5% improvement compared to baseline was observed in the NRS ease-of-breathing score at 6 and 12 months, respectively (p<0.001). No serious adverse were reported overall and no new device- or procedure-related adverse events were reported in the interval between 3 and 12 months posttreatment. TCRF treatment of SSB hypertrophy has a significant and durable effect on improving the symptoms of NAO and health-related quality of life in patients with symptoms of nasal obstruction and congestion through 12 months postprocedure.

Impact of septal deviation and turbinate hypertrophy on nasal airway obstruction: insights from imaging and the NOSE scale: a retrospective study

BackgroundThe aim of this study was to evaluate the effects of nasal septum deviation and inferior turbinate hypertrophy on nasal obstruction by utilizing the Nose Obstruction Symptom Evaluation (NOSE) values and paranasal sinus computed tomography (PSCT) findings for correct preoperative evaluation.MethodsNinety-six patients (57 males and 39 females) aged between 18 and 54 years (mean age, 30.3 ± 9.7 years) participated in this study. Among them, 56 patients underwent septoplasty combined with inferior turbinate outfracture, while 40 patients underwent septoplasty alone. Preoperative nasal examinations were performed on all patients. The direction, location, nasal septum deviation classification, and inferior turbinate hypertrophy size classification were carefully evaluated and compared with the NOSE survey results. PSCT of 56 patients were evaluated and classified by calculating the coronal location of septum deviation, the axial location of septum deviation, the coronal angle of septum deviation, and the axial angle of septum deviation.ResultsA positive correlation was found between the coronal location of the septal deviation and the preoperative NOSE 2, and the NOSE total, and the difference of postoperative and preoperative NOSE (p = 0.032, p = 0.007, p = 0.021, respectively). There was a statistically significant relationship between the coronal location of the septal deviation classification and the NOSE preoperative total values (p = 0.26). A negative statistically significant correlation was found between inferior turbinate hypertrophy and preoperative NOSE 5 values (p = 0.029).ConclusionWe conclude that the combination of PSCT and the NOSE scale is helpful in determining the severity of nasal obstruction prior to surgery. Specifically, we found that nasal septum deviations located in the anterior and coronal planes have a greater impact on nasal obstruction compared to deviations in the axial plane. Inferior turbinate fracture does not provide more benefit than septoplasty alone in treating patients’ nasal obstruction. These findings emphasize the importance of a comprehensive approach in addressing nasal obstruction for optimal patient outcomes.

Two-year outcomes of radiofrequency device treatment of the nasal valve for nasal airway obstruction.

Temperature-controlled radiofrequency (TCRF) device treatment of nasal valve dysfunction (NVD) was superior to a sham procedure control in reducing the symptoms of nasal airway obstruction (NAO) in this randomised controlled trial (RCT). Two-year outcomes for 108 patients actively treated in a prospective, multicenter, patient-blinded RCT were used to determine treatment effect durability and changes in medication/nasal dilator usage. A responder was defined as ≥ 20 reduction in NOSE score or 1 reduction in severity class. The mean (SD) age of patients was 48.5 (12.3) years; 66 (61.1%) women. Baseline NOSE score was 76.3. The 2-year responder rate was 90.4% and NOSE score treatment effect was -41.7; 54.7% improvement. Of 57 patients using medications/nasal dilators at baseline, 45 (78.9%) either stopped all use (33.3%) or stopped/decreased (45.6%) use in >=1 class at 2 years. Concurrent septal deviation, septal swell body, or turbinate enlargement did not significantly affect the odds of exhibiting a NOSE score of ≤ 25 at 2 years. TCRF device treatment of NVD resulted in significant and sustained improvements in the symptoms of NAO at 2 years, accompanied by a substantial reduction in medication/nasal dilator use.

Correlation between Subjective Nasal Patency and Nasal Capacity in Young Adults: A Pilot Study with a Prototype Device-A Nasoorospirometer.

Background: Nasal airway obstruction (NAO) is characterised by high resistance in the nasal cavity with a collapsible and narrowed upper airway and is an integral part of OSA pathophysiology. The literature demonstrates that the identification of high-risk OSA in the young adult population leads to the prevention of later health consequences. A nasoorospirometer is a prototype device that measures nasal capacity during inspiration. The basis for measurement is a Wheatstone bridge and a thermal anemometer. The parameters are recorded via hot wire anemometry (HTA) with velocity measurements in the airflow field. Therefore, this pilot study aimed to test the feasibility of the device by examining a young adult sample. The secondary aim was to determine whether subjective NAO correlates with nasal capacity and whether NAO corresponds with anthropometric parameters and individual risk of OSA. Methods: A group of 31 participants (mean age 24.9 years) underwent a thorough laryngological examination. The nasoorospirometer was used to measure objective NAO (nasal capacity), the NOSE scale was used to gain subjective NAO evaluation, and the Berlin Questionnaire for the risk of OSA. Results: A correlation analysis confirmed no significant associations between the subjective and objective measures (p > 0.05). Higher BMI and neck circumference are associated with lower NAO and higher nasal patency in the population of young adults (r: 0.32-0.45; p < 0.05). The risk of OSA showed no statistically significant association (p > 0.05). Conclusions: We presented three methods of NAO assessment: subjective participant evaluation, objective nasoosopirometry, and objective laryngological assessment. However, the use of a nasoorospirometer with anthropometric measures in young adults needs to be verified in future studies.

Economic impact analysis of a minimally invasive temperature-controlled radiofrequency device versus nasal surgery for the treatment of nasal airway obstruction in the United States

Objective To determine the economic impact of a minimally invasive temperature-controlled radiofrequency (TCRF) device for treating nasal airway obstruction (NAO). Methods A budget impact model was developed for two scenarios: a reference scenario of functional rhinoplasty surgery with concomitant septoplasty and inferior turbinate reduction (ITR) performed in the hospital outpatient department where TCRF is not an available treatment option and a new scenario consisting of in-office TCRF treatment of the nasal valve and ITR. A payor perspective was adopted with a hypothetical population plan size of one million members. Costs were estimated over a time horizon of 4 years. The eligible population included patients with severe/extreme NAO and nasal valve collapse (NVC) as the primary cause or significant contributor. Data inputs were sourced from targeted literature reviews. Uncertainty within the model structure and input parameters was assessed using one-way sensitivity analysis. Results The introduction of a TCRF device resulted in population-level cost savings of $20,015,123 and per-responder average cost savings of $3531 through a 4-year time horizon due to lower procedure costs and complication rates of the device relative to the surgical comparator. Results were robust when varying parameter values in sensitivity analyses, with cost savings being most sensitive to the prevalence of NAO and estimated response rates to functional rhinoplasty and TCRF. Conclusions In patients with severe/extreme NAO, with NVC as the primary or major contributor, introducing TCRF with ITR as a treatment option demonstrates the potential for significant cost savings over functional rhinoplasty with septoplasty and ITR.

Breathing changes following mini-implant-supported maxillary skeletal expander treatment in late adolescent or adult patients : Assessment of objective and subjective functional breathing changes.

The aim of this study was to assess objective and subjective breathing changes in adult patients who underwent maxillary skeletal expansion with the mini-implant-supported maxillary skeletal expander (MSE). Twenty-nine patients (mean age 18.1 ± 4.3years) who underwent expansion using the MSE were compared pre- and posttreatment and with acontrol group (mean age 19.9 ± 2.6years) to assess objective and subjective functional breathing changes. Objective measurements of the airway including peak nasal inspiratory flow (PNIF) and peak oral inspiratory flow (POIF) were measured utilizing the In-Check medical device (Clement Clarke, Harlow, United Kingdom). Patients reported subjective breathing assessment utilizing the visual analog scale (VAS). Intragroup comparisons were performed with Wilcoxon tests and intergroup comparison with Mann-WhitneyU tests. Spearman correlation coefficients were calculated among the studied variables (P < 0.05). Following MSE treatment, there were significantly higher values for PNIF total (P < 0.0001), PNIF right (P < 0.0001), PNIF left (P < 0.0001), and POIF (P < 0.01) compared to pretreatment and control group results. Also, patients reported asignificant decrease in troubled breathing as measured by the VAS for breathing through the right nostril (P < 0.01), left nostril (P < 0.001), and both nostrils (P < 0.01). Comparing the objective and subjective variables for both the pre-MSE or post-MSE groups, the results indicated no significant correlation between total PNIF and total VAS. However, the values had significant correlations between PNIF and VAS on each side when the patients were asked to block one nostril. Objective functional breathing measurements were increased immediately after treatment with MSE. Subjective functional breathing measurements changes were significantly higher after MSE treatment and compared with the control group. MSE presents anonsurgical alternative to achieving orthopedic expansion in adult patients which may provide abenefit for patients with nasal airway obstruction.

Effects of Mucosal Decongestion on Nasal Aerodynamics: A Pilot Study.

Mucosal decongestion with nasal sprays is a common treatment for nasal airway obstruction. However, the impact of mucosal decongestion on nasal aerodynamics and the physiological mechanism of nasal airflow sensation are incompletely understood. The objective of this study is to compare nasal airflow patterns in nasal airway obstruction (NAO) patients with and without mucosal decongestion and nondecongested healthy subjects. Cross-sectional study of a convenience sample. Academic tertiary medical center. Forty-five subjects were studied (15 nondecongested healthy subjects, 15 nondecongested NAO patients, and 15 decongested NAO patients). Three-dimensional models of the nasal anatomy were created from computed tomography scans. Steady-state simulations of airflow and heat transfer were conducted at 15 L/min inhalation rate using computational fluid dynamics. In the narrow side of the nose, unilateral nasal resistance was similar in decongested NAO patients and nondecongested healthy subjects, but substantially higher in nondecongested NAO patients. The vertical airflow distribution within the nasal cavity (inferior vsmiddle vssuperior) was also similar in decongested NAO patients and nondecongested healthy subjects, but nondecongested NAO patients had substantially less middle airflow. Mucosal cooling, quantified by the surface area where heat flux exceeds 50 W/m2, was significantly higher in decongested NAO patients than in nondecongested NAO patients. This pilot study suggests that mucosal decongestion improves objective measures of nasal airflow, which is consistent with improved subjective sensation of nasal patency after decongestion.

Peak Nasal Inspiratory Flow (PNIF) for Nasal Breathing Evaluation.

Measuring nasal airflow and nasal breathing has been a major goal of rhinology. Many objective methods for measuring nasal airflow or nasal airway resistance or dimensions provide valuable data but are time-consuming and require expensive equipment and trained technicians, thus making these methods less practical for clinical practice. Peak nasal inspiratory flow (PNIF) measurement is fast, unexpensive, noninvasive, and able to provide an objective evaluation of nasal airflow in real-time. Unilateral PNIF measurements allow separated evaluation of each side of the nasal airway and may prove particularly useful when clinical assessment detects significant asymmetry between both nasal cavities.PNIF measurements are most useful for assessing changes in nasal airflow achieved by any form of therapy, including surgical treatment of the nasal airway. These measurements generally correlate with other objective methods for nasal airway evaluation, but not unequivocally with patient-reported evaluation of nasal breathing. Nevertheless, as low PNIF values prevent the sensation of a suitable nasal breathing, PNIF measurement may also prove useful to optimize the decision of how to best address patients with complaints of nasal airway obstruction.

Comparison of nasal valve dysfunction treatment outcomes for temperature-controlled radiofrequency and functional rhinoplasty surgery: a systematic review and meta-analyses.

Nasal valve dysfunction (NVD) is a substantial contributor to nasal airway obstruction. Minimally-invasive temp-erature-controlled radiofrequency (TCRF) treatment of the nasal valve is available and comparison with surgical techniques is warranted. Databases: Medline (PubMed), Embase, Cochrane Library. adults with preprocedural nasal obstruction symptom evaluation (NOSE) score ≥45. Treatment effects were derived from a random effects model and reported as weighted mean difference in NOSE score between baseline; 3, 6, and 12 months postprocedure. Of 2529 initial articles, 5 studies describing TCRF treatment and 63 studies describing functional rhinoplasty were included. Pooled effect sizes for TCRF treatment and functional rhinoplasty were comparable in all analyses. TCRF treatment of the internal nasal valve for NVD was associated with sustained effects comparable to functional rhinoplasty addressing the nasal valve only, rhinoplasty without concomitant turbinate treatment, and all rhinoplasty.

CONCLUSIONS: TCRF device treatment of NVD resulted in significant and sustained improvements in the symptoms of NAO at 2 years, accompanied by a substantial reduction in medication/nasal dilator use.

Peak nasal inspiratory flow in the assessment of nasal airway obstruction

Nasal congestion is one of the most common complaints in otolaryngology practice and can significantly impact the quality of life for patients. Objective and subjective assessments provide different information, but objective assessment of nasal obstruction is crucial for accurate diagnosis and appropriate treatment. This review demonstrates that peak nasal inspiratory flow (PNIF) is a reproducible and reliable measure of objective nasal patency. It is inexpensive, easy to use, suitable for serial measurements, and can be applied to patients of different age groups. PNIF is recommended for use in every outpatient clinic that treats patients with nasal congestion. To summarize the data on the application of PNIF in diagnosing conditions of the nasal airways. Publications (articles and relevant abstracts) available in the PubMed and eLibrary databases were analyzed. PNIF offers an objective and non-invasive assessment of nasal airflow, aiding in diagnosis, therapy monitoring, and preoperative planning. Further research, standardization, and establishment of normative data will enhance the informative value of peak nasal inspiratory flow in assessing nasal obstruction.

Impact of different fracture types in the pyriform buttress area on nasal airway function

IntroductionFractures in the pyriform buttress area adversely affect facial appearance and nasal airway patency. Nasal airway function has received less attention than aesthetic problems in the literature. This retrospective study classified the different fracture types in this area and determined their impact on nasal airway function.MathodsThree-dimensional computed tomography images of patients with fractures in the pyriform buttress area were analyzed to identify the exact fracture pattern. The nasal airway functions were evaluated and compared between patients with different fracture patterns using acoustic rhinometry, rhinomanometry, and the nasal obstruction symptom evaluation scale.Results Overall, 47 patients, including 16 with type I fractures (high fracture line; group I), 16 with type II fractures (intermediate fracture line; group II), and 15 with type III fractures (low fracture line; group III), were included in the study. The mean minimal cross-sectional area (MCA), total nasal inspiratory resistance (Tri) and total nasal expiratory resistance (Tre) of group I were 0.51 ± 0.06 cm2, 1.67 ± 0.11 kPa L−1 s−1, and 1.66 ± 0.12 kPa L−1 s−1, respectively; those of group II were 0.48 ± 0.07 cm2, 1.89 ± 0.15 kPa L−1 s−1, and 1.88 ± 0.14 kPa L−1 s−1, respectively; and those of group III were 0.36 ± 0.04 cm2, 1.94 ± 0.21 kPa L−1 s−1, and 2.01 ± 0.34 kPa L−1 s−1, respectively. The nasal obstruction symptom evaluation (NOSE) scale scores for groups I, II, and III were 7.188, 9.813, and 13.27, respectively.Conclusion Therefore, the severity of the nasal airway obstruction depends on the displacement of the fractured bones in patients with fractures in the pyriform buttress area. The most profound nasal obstruction occurs in patients with the lowest fracture line.

Clinical Management of Choanal Atresia

Choanal atresia (CA) is a rare congenital anomaly of the nasal airway with an incidence of 1/5000 to 1/9000, which may occur unilateral (uCA) or bilateral (bCA). bCA manifests as an acute emergency immediately after birth by airway obstruction and paradoxical cyanosis, whereas uCA may present with a heterogeneous clinical picture in addition to unilateral nasal airway obstruction. Fiber endoscopic examination and cranial computed tomography are the gold standard in the diagnosis of CA. CA often occurs in association with congenital malformation syndromes, among which CHARGE syndrome stands out. Due to cardiopulmonary instability and difficult intubation conditions, syndromic CA patients should be considered as a separate risk group. After securing the airway, bCA must be treated surgically without delay, whereas correction of uCA should not be performed until after six months of age. Endoscopic techniques are the surgical standard in the treatment of CA. Different approaches can be distinguished: transnasal puncture of the atresia plate with subsequent extension medially and laterally, creation of a septal window with subsequent resection of the posterior vomer and atresia plate, and elevation of mucoperiosteal flaps with subsequent opening of the atresia plate. The transpalatal approach should only be employed in anatomically complex cases. The use of conventional choanal stents in the primary treatment of CA is increasingly rejected and should be reserved for high-risk constellations. Similarly, local application of mitomycin C should be avoided.

Prevalence and Identification of Nasal Airway Obstruction in Patients Presenting to Otolaryngology Clinics: Results From a Large Descriptive Practice Survey.

Objective: Determine the prevalence of nasal airway obstruction (NAO) in patients presenting to general otolaryngology clinics using the Nasal Obstruction Symptom Evaluation Scale (NOSE) score as a screening tool. Study Design: The clinic staff at 149 otolaryngology specialty clinics geographically distributed in the United States administered the NOSE Scale assessment to 3533 patients presenting to the clinics over a period of 1 week, regardless of the reason for the visit. All patients completed the NOSE Scale score, and additional data were collected, including the primary reason for the visit. Demographic and patient characteristics were summarized using frequencies and percentages for categorical variables. Results: The overall mean NOSE Scale score for the 3533 patients surveyed was 37.6 (SD 31.5). A total of 37.4% (1320/3533) of surveyed patients, regardless of visit reason, had severe/extreme NAO symptoms. Overall, the most common visit reason category was "Other" (61.2%, 2162/3533), followed by "NAO" (22.6%, 798/3533) and "Sinus" (16.2%, 573/3533). The mean NOSE scores for patients in each of the visit categories were 23.4 (SD 25.9), 64.7 (SD 23.3), and 53.3 (SD 28.1); for "Other," "NAO," and "Sinus," respectively. Among the patients coming in with "NAO" or "Sinus" as a primary complaint, 76.2% (608/798) and 57.2.% (328/573) had severe or extreme NOSE scores. A total of 17.8% (384/2162) of patients coming in for "Other" reasons had NOSE scores indicating severe/extreme NAO symptoms. Conclusions: The findings of this large, descriptive otolaryngology practice survey found a high prevalence of moderate to severe/extreme NAO among patients presenting to otolaryngology practices. Incorporating assessments, such as the NOSE Scale score and other diagnostic practices into the patient intake workflow and assessments, could help identify symptomatic NAO patients that might otherwise be overlooked.

Effect of ambient temperature and respiration rate on nasal dominance: preliminary findings from a nostril-specific wearable

The nasal dominance (ND) determination is crucial for nasal synchronized ventilator, optimum nasal drug delivery, identifying brain hemispheric dominance, nasal airway obstruction surgery, mindfulness breathing, and for possible markers of a conscious state. Given these wider applications of ND, it is interesting to understand the patterns of ND with varying temperature and respiration rates. In this paper, we propose a method which measures peak-to-peak temperature oscillations (difference between end-expiratory and end-inspiratory temperature) for the left and right nostrils during nasal breathing. These nostril-specific temperature oscillations are further used to calculate the nasal dominance index (NDI), nasal laterality ratio (NLR), inter-nostril correlation, and mean of peak-to-peak temperature oscillation for inspiratory and expiratory phase at (1) different ambient temperatures of 18 °C, 28 °C, and 38 °C and (2) at three different respiration rate of 6 bpm, 12 bpm, and 18 bpm. The peak-to-peak temperature (T pp) oscillation range (averaged across participants; n = 8) for the left and right nostril were 3.80 ± 0.57 °C and 2.34 ± 0.61 °C, 2.03 ± 0.20 °C and 1.40 ± 0.26 °C, and 0.20 ± 0.02 °C and 0.29 ± 0.03 °C at the ambient temperature of 18 °C, 28 °C, and 38 °C respectively (averaged across participants and respiration rates). The NDI and NLR averaged across participants and three different respiration rates were 35.67 ± 5.53 and 2.03 ± 1.12; 8.36 ± 10.61 and 2.49 ± 3.69; and −25.04 ± 14.50 and 0.82 ± 0.54 at the ambient temperature of 18 °C, 28 °C, and 38 °C respectively. The Shapiro–Wilk test, and non-parametric Friedman test showed a significant effect of ambient temperature conditions on both NDI and NLR. No significant effect of respiration rate condition was observed on both NDI and NLR. The findings of the proposed study indicate the importance of ambient temperature while determining ND during the diagnosis of breathing disorders such as septum deviation, nasal polyps, nosebleeds, rhinitis, and nasal fractions, and in the intensive care unit for nasal synchronized ventilator.

Transoral Septoplasty before Le Fort I Downfracture: A Novel Functional Rhinoplasty Technique.

Individuals with maxillary dentofacial deformities commonly have preexisting nasal airway obstruction with associated nasal septal deviation. Combination bimaxillary procedures with intraoral septoplasty after maxillary downfracture have been demonstrated to address dentofacial deformities and nasal obstruction simultaneously. Although effective, current transoral septoplasty techniques offer limited visualization of the superior septum and are challenging to perform due to septal mobility after Le Fort I downfracture. Here, we describe a novel approach in which a transoral septoplasty is performed before completion of the Le Fort I maxillary downfracture, improving septal stability during the dissection and affording better visualization of the septal L-strut for precise cartilage resection.

Pediatric Functional Rhinoplasty.

Surgery on the growing pediatric nose poses many questions regarding the indications and proper timing. Historically, surgeries on the pediatric nose led to facial growth alterations so many urged caution and waiting until skeletal maturity at the age of 18. However, animal studies showed some promise that facial growth may not be affected. Investigations into effects of pediatric sinus surgery and septal surgery on facial growth showed no issues. The external nose is somewhat different in that minor variations potentially can grow to a cosmetic deformity. However, numerous studies on facial growth show, to date, that it is not affected, and that surgery is safe. The caveat that one uses is the techniques of cartilage sparing and preservation, which have been studied and shown to be safe. There are ways to measure the effectiveness of surgery in relieving nasal airway obstruction both objectively and, more recently, subjectively. It is essential to treat pediatric nasal airway obstruction to avoid other facial growth problems, such as mouth breathing, snoring, malocclusion, and obstructive sleep apnea.
