Background: Nasal obstruction due to deviated septum is commonly treated with conventional septoplasty. This surgery however is inadequate in cases of compromised nasal valves and leads to persistent symptoms. Hence, we stressed the evaluation of nasal valves before septal surgery & studied the outcome of  the patients with valve area correction. Aim: To prove the significance of inner nasal valve in nasal surgery. Objective : To analyse the outcome of  Open septoplasty. Methodology:A  retrospective review of  our patients undergoing Open septoplasty was analysed from April 2016 to January 2021. The preoperative and post operative evaluations were calculated & statistically analysed. Results : A total of 400 patients underwent Open septoplasty. Out of which 392(98%) showed symptomatic improvement in breathing difficulty &   380(95%) were happy with the asthetic improvement.  Conclusion: Open septoplasty and Spreader grafts is best solution to improve Internal Nasal valve angle. Rim graft to improve external valve collapse. Spreader graft also gives asthetic & functional improvement

AbstractObjective:This paper presents a novel method for spreader graft placement without dorsum resection in patients who have a deviated septum with a narrow internal nasal valve angle.Methods:A Killian incision was used for the endonasal septoplasty, and all spreader grafts were harvested from excised deviated septal cartilages. Procedures were conducted under general anaesthesia at the same centre by the same surgical team that performed the endonasal procedure. Successful placement of spreader grafts was achieved endonasally.Conclusion:Although the endonasal placement of spreader grafts seems to be more difficult than placement conducted by an open approach technique, an endonasal procedure has many advantages. Our technique provides surgeons with the opportunity to shorten operation time, obtain autologous septal graft material and secure the columellar architecture. Surgeons familiar with the classical (endonasal) septoplasty procedure can easily apply this technique to widen a narrow internal nasal valve angle, without corrupting nasal integrity.

Objectives: The relative importance of the nasal valve relative to the remainder of the nasal airway remains unknown. The goal of this article was to objectively measure the shape of the nasal inlet and its effect on downstream airflow and nasal cavity volume using a physical model and a physiologic flow model. Methods: A patient who had isolated nasal valve surgery and had pre- and postoperative computed tomography scans available for analysis was studied. Nasal inlet shape measurements, computational fluid dynamics, and nasal volume analysis were performed using the computed tomography data. In addition, a physical model was used to determine the effect of nasal obstruction on downstream soft tissue. Results: The postoperative shape of the nasal inlet was improved in terms of length and degree of tortuosity. Whereas the operated-on region at the nasal inlet showed an only 25% increase in cross-sectional area postoperatively, downstream nonoperated sites in the nasal cavity revealed increases in area ranging from 33% to 51%. Computational fluid dynamics analysis showed that airway resistance decreased by 42%, and pressure drop was reduced by 43%. Intraluminal mucosal expansion was found with nasal obstruction in the physical model. Conclusion: By decreasing the degree of bending and length at the nasal valve, inspiratory downstream nonoperated sites of the nasal cavity showed improvement in volume and airflow, suggesting that the nasal valve could play an oversized role in modulating the aerodynamics of the airway. This was confirmed with the physical model of nasal obstruction on downstream mucosa.

Abstract Background Insufficient support of the nasal mid-vault during rhinoplasty can cause significant complications. Accordingly, surgeons recently pay much more attention to the preservation of nasal patency. The spreader graft is the gold standard technique for the reconstruction of nasal mid-vault. Objectives The objective of this study was to compare the spreader graft and spreader flap in terms of aesthetic and functional outcomes. Methods An inclusive search was performed using PubMed/Medline, Google Scholar, Cochrane Library databases up to April 2021. Multiple aesthetic and functional factors including dorsal aesthetic lines restoration, satisfaction rate, internal nasal valve angle improvement, nasal obstruction symptom evaluation (NOSE) scale, and active anterior rhinomanometry (AAR) were evaluated. Also, a meta-analysis was performed on included articles that provided adequate data for mentioned factors. Results After excluding papers that did not conform with the selection criteria, 10 articles with a total sample size of 567 cases with a mean age of 27.7 (range: 18- 65) were finally included. Analysis of the data revealed no statistically significant difference between the spreader graft and spreader flap techniques in terms of dorsal aesthetic lines restoration, internal nasal valve angle improvement, NOSE scale, and AAR. Conclusions However, in terms of satisfaction rate, the analyzes indicated that spreader graft has significantly superior aesthetic outcomes. Generally, in case of appropriately selected patients, there is no statistically significant difference between spreader graft and spreader flap techniques in terms of aesthetic and functional outcomes.

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.
