Purpose: To evaluate endoscopic long-range optical coherence tomography system combined with a pressure sensor to concurrently measure internal nasal valve cross-sectional area and intraluminal pressure.
Methods: A pressure sensor was constructed using an Arduino platform and calibrated using a limiter-controlled vacuum system and industrial absolute pressure gauge. Long-range optical coherence tomography imaging and pressure transduction were performed concurrently in the naris of eight healthy adult subjects during normal respiration and forced inspiration.
Objective: Surgical simulators aimed at mimicking elements of rhinoplasty surgery, specifically those aimed at improving cartilage suturing, are not available. Here, we present a surgical simulator for spreader graft placement that uses cartilage rather than synthetic materials and gauge improvement using objective measures for suture placement accuracy, speed, and efficiency of hand motion.
Methods: Twenty-two otolaryngologists in two groups (residents [10] and experts [12]) were instructed to secure the two spreader graft specimen into position with three mattress sutures on a nose model that used porcine septal cartilage as a proxy for the human counterpart.

Importance: Postoperative packing in nasal surgery often results in nasal obstruction and discomfort. Commercially available silicone intranasal airways (IAs) serve as dual-nasal airway tubes aimed at alleviating this process, but the safety and efficacy of these devices are unknown.
Objective: To evaluate the safety and efficacy of an intraoperatively placed IA device in rhinoplasty and nasal surgery.
Background: Optimal antibiotic prophylaxis duration in head and neck clean-contaminated free-flap cases is unknown.
Methods: A systematic review/meta-analysis was conducted using PubMed/MEDLINE, Cochrane Library, Web-of-Science, and Scopus databases.
Results: Of the 3755 searched articles, 5 articles were included for a total of 861 patients.
Laser treatment for posttraumatic injury offers the clinician the unique opportunity for early intervention in mediating early scar formation, or for reducing the appearance of scars after maturation. In this review, the authors focus on the mechanisms by which lasers exert their therapeutic effects, highlighting several popular lasers and dosimetry used, and underscoring the power of combined surgical scar revision in managing posttraumatic facial scars.

Objective: To assess the most attractive lip dimensions of white women based on attractiveness ranking of surface area, ratio of upper to lower lip, and dimensions of the lip surface area relative to the lower third of the face.
This study examined 50 years of facial images of fashion models to determine a trend toward fuller lips.

While excessive liver granulomatous responses can lead to more severe fibrosis and circulatory impairment in chronically infected host.

To ascertain if changes in the endoplasmic reticulum (ER) stress marker, glucose-regulated-protein-78 (GRP78) can serve as a prognosticator in endometrial cancer, we examined GRP78 expression in patient samples to determine its association with clinical outcome.
Methods: A retrospective cohort study was conducted in endometrial cancer patients.
