“…Nasal wall collapse is determined by the interaction of the 3 main factors: atmospheric pressure outside the nostril, static pressure in the nasal cavity, and elasticity (rigidity) of the nasal wall. 7 According to the Bernoulli equation, 8 the static pressure tends to decrease in the nasal valve area, where the velocity increases due to the reduced cross-sectional area. The lateral wall may collapse inward in the presence of a large pressure drop occurring in the nasal valve area.…”

Objectives: In clinical practice, lateral nasal wall collapse during forced inspiration is widely regarded as a sign of nasal obstruction or criterion indicating nasal valve surgery. This study aims to evaluate the relationship between the degree of lateral nasal wall collapse and subjective nasal obstruction. In addition, factors related to lateral nasal wall collapse were also investigated. Methods: In this study, lateral nasal wall collapse is determined by the degree of lateral nasal wall triangle (LNWT) area reduction on frontal view during forced inspiration compared to quiet inspiration. LNWT area ratio of the patient and control groups was compared. The relationship between the lateral nasal wall collapse and clinical factors including symptom scores, nasal valve angles, skin thickness were evaluated. Results: The average LNWT area ratio of the patient (n = 24) and control groups (n = 27) was 0.96 and 0.83 respectively ( P = .001). Symptom score (NOSE and VAS) is not related to the degree of lateral nasal wall collapse. Moreover, nasal valve angle and skin thickness were also not related to the degree of lateral nasal wall collapse. In 14 of the 19 patients, the more obstructed side corresponded to the side of narrower nasal valve angle, and 5 were not. Conclusion: Lateral nasal wall collapse is not related to a patients’ nasal obstruction.

“…The primary result of this study suggests that the control group exhibited a larger degree of lateral nasal wall collapse compared with the case group. Nasal wall collapse is determined by the interaction of the three main factors: atmospheric pressure outside the nostril, static pressure in the nasal cavity, and elasticity (rigidity) of the nasal wall (7). According to the Bernoulli equation( 8), the static pressure tends to decrease in the nasal valve area, where the velocity increases due to the reduced cross-sectional area.…”

Objectives In clinical practice, lateral nasal wall collapse during forced inspiration is widely regarded as a sign of nasal obstruction or criterion indicating nasal valve surgery. This study aims to evaluate the relationship between the degree of lateral nasal wall collapse and subjective nasal obstruction. Design Case-Control study Setting Tertiary centre hospital Participants Case group consisted of 24 patients who had been diagnosed with a deviated nasal septum or nasal valve stenosis. Control group consisted of 27 volunteers with no nasal obstruction symptoms and no septal deviation on nasal endoscopy. Main outcome measures Lateral nasal wall collapse is determined by the degree of lateral nasal wall triangle (LNWT) area reduction on frontal view during forced inspiration compared to quiet inspiration. LNWT area ratio of the patient and control groups was compared. The relationship between the lateral nasal wall collapse and clinical factors including symptom scores, nasal valve angles, skin thickness were evaluated. Results The average LNWT area ratio of the patient (n=24) and control groups (n=27) was 0.96 and 0.83 respectively (p=0.001). Symptom score (NOSE and VAS) is not related to the degree of lateral nasal wall collapse. Moreover, nasal valve angle and skin thickness were also not related to the degree of lateral nasal wall collapse. In 14 of the 19 patients, the more obstructed side corresponded to the side of narrower nasal valve angle, and 5 were not. Conclusion Lateral nasal wall collapse is not related to a patients’ nasal obstruction.

“…Only recently, diagnostic recording of alar collapse was achieved by computer-assisted rhinomanometry 8 and inspiratory and fixed nasal valve collapse was differentiated by acoustic rhinometry. 9 Standard techniques of septoplasty often fail to create the desired results.…”
