Functional Septorhinoplasty in Unilateral and Bilateral Nasal Obstruction: A Comparison of Patient-Reported Outcomes.

Purpose: Functional septorhinoplasty is an effective treatment for nasal airway obstruction. Little distinction exists between bilaterally and unilaterally obstructed patients in literature. Our study evaluates outcomes in patients with unilateral nasal airway obstruction compared to those with bilateral nasal airway obstruction as measured by nasal obstruction symptom evaluation scores following functional septorhinoplasty.

Comparing Patient-Reported Outcomes with Computational Fluid Dynamics-Derived Nasal Airflow After Nasal Airway Surgery: Prioritizing the Patient's Perception of Nasal Obstruction.

Some patients report persistent nasal obstruction after surgical treatment despite objective improvement. To compare patients' perceptions of nasal obstruction after surgery with objective nasal airflow as determined by computational fluid dynamics (CFD) modeling: (1) Is perception driven by a more symptomatic side? (2) Can symptom improvement be predicted with CFD modeling? Pre/postoperative Nasal Obstruction Symptom Evaluation (NOSE) and visual analog scale (VAS) score were collected for patients undergoing nasal obstruction surgery. Pre/postoperative computed tomography was used to generate patient-specific airway models for CFD simulation at 15 L/min resting inspiration.

Parameter characteristics in intranasal drug delivery: A key to targeting medications to the olfactory airspace.

Background: The nose is a viable pathway for topical drug delivery to the olfactory cleft for treatment of obstructive smell loss and nose-to-brain drug delivery. This study investigates how variations in nasal vestibule morphology influence intranasal spray drug transport to the olfactory cleft and olfactory roof/bulb regions.

Methods: The unilateral nasal vestibule morphology in three healthy subjects with healthy normal nasal anatomy was classified as Elongated (Subject DN001), Notched (Subject DN002), and Standard (Subject DN003).

Nasal airway obstruction in patients with cleft lip nasal deformity: A systematic review.

Background: Cleft lip nasal deformity (CLND)-associated nasal airway obstruction (CL-NAO) may be inadequately characterized, with its functional implications subsequently underappreciated and neglected. The purpose of this systematic review is to (1) summarize the available assessment results in CL-NAO, (2) evaluate the reliability of current assessment tools, and (3) identify ongoing gaps and inconsistencies for future study.

Methods: A systematic search of the MEDLINE, EMBASE, and Scopus databases was performed for articles studying CL-NAO.
