“…NO-VAS is commonly used in the assessment of nasal obstruction and has been shown to correlate strongly with rhinomanometry nasal airflow resistance in patients with allergic rhinitis (26) . A recent study shows moderate negative correlation between unilateral NO-VAS and same side unilateral PNIF in patients undergoing septorhinoplasty (27) . Meanwhile, the extensively used and region with the largest non-western immigrant population (28) .…”

Background: Nasal septoplasty is a common surgical procedure, but a significant number of patients report equal, or some even worsened, symptom load postoperatively. Rhinologists struggle to find objective tests that adequately reflects disease burden. This study aimed to evaluate the correlation between the PNIF measurement of the most obstructed side with patient reported outcomes. Methods: Bilateral and unilateral PNIF measurements were performed before and after topical decongestion in 528 patients scheduled for surgery due to nasal obstruction. Subjective outcomes were measured using Nasal Obstruction VAS and SNOT-22 with subdomains. Correlations between subjective and objective measurements were calculated and further explored using multivariate regression analyses. Results: Significant negative correlations between PNIF and patient reported outcomes were found. Both bilateral and minimal unilateral PNIF correlations with NO-VAS were equal and stronger than correlations with SNOT-22 including subdomains concerning problems with nasal obstruction. Minimal unilateral PNIF did not show statistically significant gender difference. Topical decongestion decreased statistical correlations. Conclusions: The minimal unilateral PNIF shows a statistically significant but weak negative correlation with preoperative patient reported nasal obstruction, and values do not differ between genders. Clinical evaluation of patients presenting complaints of nasal obstruction could be supported by minimal unilateral PNIF.

“…The INV has been reported to be the point of highest resistance in the nasal airway (14). The INV is a cross-sectional area bounded medially by the dorsal septum, laterally by the caudal portion of the upper lateral cartilage, and inferiorly by the head of the inferior turbinate (15,16). This cross-sectional area was calculated by the same author and measurement was repeated to ensure precision.…”

Background/Aim: We hypothesized that improved functional outcome after preservation rhinoplasty can be validated by radiological analyses. Patients and Methods: In this retrospective study, five patients were included. Radiological assessment was evaluated by cone-beam computed tomography. Patient satisfaction regarding nasal function was evaluated by a Likert scale from 0 to 10 (0=poor result; 10=very satisfied). Results: After a mean follow-up of 5±1 months (range=4-6 months), significantly improved function was noted by all patients, with a mean Likert scale of 9.2±0.45 (preoperative score=2.8±0.8, p=0.0079). These results are in line with the radiological results, showing an improved internal nasal valve angle (preoperative=26.2˚±1.8v s. postoperative=32.3˚±1.2˚, p=0.02). Conclusion: Our study showed that besides nasal appearance, nasal function can also be dramatically improved after preservation rhinoplasty.

“…Patients were recruited if they had at least one of AR, CRS or DNS or any combination of these. Patients with internal valve or external valve deficiency were excluded 33 . A pragmatic approach was taken regarding patients taking oral and intranasal medications for their nasal obstruction, and these were not excluded.…”

Objectives: There is a need to develop a medical device which can accurately measure normal and abnormal nasal breathing which the patient can better understand in addition to being able to diagnose the cause for their nasal obstruction. The aim is to evaluate the accuracy of the nasal acoustic device (NAD) in diagnosing the common causes for nasal obstruction and diagnosing normal and abnormal (nasal obstruction) nasal breathing. Methods: This pilot study recruited 27 patients with allergic rhinitis (AR), chronic rhinosinusitis (CRS), and a deviated nasal septum (DNS) which represents the common causes for NO and 26 controls (with normal nasal breathing). Nasal breathing sounds were recorded by the NAD akin to two small stethoscopes placed over the left and right nasal ala. The novel outcome metrics for the NAD include inspiratory nasal acoustic score (INA) score, expiratory nasal acoustic (ENA) score and the inspiratory nasal obstruction balance index (NOBI). The change in acoustic score following decongestant is key in this diagnostic process. Results: Pre-decongestant ENA score was used to detect the presence of nasal obstruction in patients compared to controls, with a sensitivity of 0.81 (95% CI: 0.66-0.96) and a specificity of 0.77 (0.54-1.00). Post-decongestant percentage change in INA score was used to identify the presence of AR or CRS, with a sensitivity of 0.87 (0.69-1.00) and specificity of 0.72 (0.55-0.89) for AR; and a sensitivity of 0.92 (0.75-1.00) and specificity of 0.69 (0.52-0.86) for CRS. Post-decongestant inspiratory NOBI was used to identify DNS, with a sensitivity of 0.77 (0.59-0.95) and specificity of 0.94 (0.82-1.00).
