Background: Many locations for the nasal valve have been suggested, and more recently the concept of the flow-limiting segment was introduced. Rather than being controlled by an internal and external valve, flow through the nose is regulated by the cartilaginous side wall, septum, and inferior turbinate.
Objectives: The aim of this study was to assess the balanced cantilever graft (BCLG) as a technique to support the lateral nasal wall.
Methods: Patients undergoing primary open septorhinoplasty over a 2-year period were studied. Follow-up period was a minimum of 6 months to a maximum of 24 months. Subjective improvement of function was measured with a visual analog scale (VAS) and aesthetic outcomes by FACE-Q score. Objective assessment of the airway was performed with a nasal peak inspiratory flow (NPIF) meter. Strips of septal cartilage of sufficient dimensions were placed in submucosal pockets created under the area of the lateral wall to be supported.
Results: Sixty patients received BCLGs. The VAS score for nasal obstruction increased from 2.6 preoperatively to 8.1 postoperatively. FACE-Q increased from 16.7 preoperatively to 36.6 postoperatively. NPIF was 74.9 L/minute preoperatively, improving to 95 L/minute postoperatively. Statistically significant improvements were seen in these functional and aesthetic scores.
Conclusions: BCLGs support the weakened part of lateral nasal wall by their elastance. Minimal cartilage is required and the graft can be altered to support various parts of the lateral nasal wall. This graft does not cause an aesthetic deficiency whilst providing adequate support.

Hummingbirds use compensatory eye movements to stabilize both rotational and translational visual motion.

To maintain stable vision, behaving animals make compensatory eye movements in response to image slip, a reflex known as the optokinetic response (OKR). Although OKR has been studied in several avian species, eye movements during flight are expected to be minimal. This is because vertebrates with laterally placed eyes typically show weak OKR to nasal-to-temporal motion (NT), which simulates typical forward locomotion, compared with temporal-to-nasal motion (TN), which simulates atypical backward locomotion.

Background: The UK's National Health Service Test and Trace (NHSTT) program aimed to provide the most effective and accessible SARS-CoV-2 testing approach possible. Early user feedback indicated that there were accessibility issues associated with throat swabbing. We report the results of service evaluations performed by NHSTT to assess the effectiveness and user acceptance of swabbing approaches, as well as qualitative findings of user experiences from research reports, surveys, and incident reports.

The objective of this study was to analyze the sensory changes reported by patients after lateral nasal wall surgery and to assess the prevalence and severity of sensory disturbances, the factors that influence their occurrence, and their impact on patients' quality of life. The methodology adopted in this study was PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis), as well as the PICO (Population, Intervention, Comparison, Outcomes) strategy, which assisted in the development of the study's objectives. Based on the inclusion and exclusion criteria, among all the articles retrieved in the searched databases (PubMed and Google Scholar), we selected 15 articles, considered to be pertinent and relevant to the present investigation.

Introduction: The objective of this study was to evaluate the effects of the miniplate application sites in the maxilla and the applied force vector changes during skeletally supported facemask application in adolescent patients with unilateral cleft lip and palate (UCLP) using finite element model (FEM) analysis.
Methods: A FEM was obtained from a cone-beam computed tomography image of a 12-year-old female patient with UCLP. Miniplates were placed on 3 different sites of the maxilla; 500 g of advancement force was applied bilaterally, parallel (0°), and downward (-30°) to the occlusal plane.
Endoscopic endonasal approach for pituitary neuroendocrine tumor with septal mucosa incision tailored to tumor extension intending unilateral septal mucosa preservation.

Currently, the direct endonasal approach is widely used in endoscopic endonasal surgery (EES) for pituitary neuroendocrine tumor. However, a large posterior septal perforation is inevitable. We routinely utilize a modified para/transseptal approach using the combination of a Killian and a contralateral rescue flap incision (PTSA with K-R incision).
