Importance Sleep-disordered breathing (SDB) represents a spectrum of sleep-related disorders associated with significant medical comorbidities. Nasal airway surgery has been shown to improve SDB but no large-scale studies exist that describe the long-term impact of surgery on patient perception of snoring and nasal obstruction. Objective To characterize longitudinal snoring symptoms and nasal obstruction after functional nasal surgery for patients with SDB, stratified by history of snoring or obstructive sleep apnea (OSA). Design, Setting, and Participants In this prospective cohort study, patients undergoing nasal surgery between 2013 and 2017 at a tertiary academic center were surveyed using Snoring Outcome Survey (SOS) and Nasal Obstruction Symptom Evaluation (NOSE) questionnaires through 24 months postoperatively. Patient demographics, history of snoring, diagnosis of OSA, and prior nasal surgeries were analyzed. A total of 625 patients were recruited with 325 females (52.0%) and mean age of 36.3 years (Selated QOL outcomes after nasal airway surgery. Future studies using objective measures of snoring are needed to quantify the physiologic change in snoring after treatment of nasal obstruction. Level of Evidence 2c.Importance Quantitative assessment of facial function is challenging, and subjective grading scales such as House-Brackmann, Sunnybrook, and eFACE have well-recognized limitations. Machine learning (ML) approaches to facial landmark localization carry great clinical potential as they enable high-throughput automated quantification of relevant facial metrics from photographs and videos. However, the translation from research settings to clinical application still requires important improvements. Objective To develop a novel ML algorithm for fast and accurate localization of facial landmarks in photographs of facial palsy patients and utilize this technology as part of an automated computer-aided diagnosis system. Design, Setting, and Participants Portrait photographs of 8 expressions obtained from 200 facial palsy patients and 10 healthy participants were manually annotated by localizing 68 facial landmarks in each photograph and by 3 trained clinicians using a custom graphical user interface. A novel ML modelions and Relevance Retraining a computer vision facial landmark detection model with fewer than 1600 annotated images of patients significantly improved landmark detection performance in frontal view photographs of this population. The new annotated database and facial landmark localization model represent the first steps toward an automatic system for computer-aided assessment in facial palsy. Level of Evidence 4.Importance There are no surgical techniques described to treat synkinesis and concurrent facial asymmetry. We describe our innovative and effective approach and technique. Objective To improve the spontaneous smile mechanism as well as facial symmetry in patients with synkinesis not only during the smile mechanism but also at rest. Design Surgical pearls-surgical technique description. Setting Private practice. Participants Patients who underwent the operation.Pedicled buccal fat flaps have demonstrated great utility for oral reconstructions. We present a retrospective case description detailing the utility of the buccal fat pad (BFP) as an anterior maxillary flap for midfacial and lower eyelid volumization and reconstruction. A 64-year-old healthy female had undergone bilateral lower blepharoplasty with silicone tear tough implantation, complicated by infection of the right tear trough implant. Delayed implant removal resulted in chronic infection and inflammation producing significant right lower eyelid retraction, and full-thickness scarring to the orbital rim. Reconstruction was performed, featuring the creation of a midfacial subperiosteal pocket and to access the BFP, which was mobilized and secured to the inferior orbital rim. Long-term follow-up confirms ongoing viability of the surgical intervention. Herein, the BFP is shown to be a source of vascularized volume in reconstructive periorbital surgery.Importance This is the first eye-tracking study to use a tasked age estimation paradigm to explore the facial cues of age as seen by casual observers. Objectives Determine where observers gaze on faces when tasked with estimating an individual's age. Design, Setting, and Participants This was a prospective controlled experiment, which took place at an academic tertiary referral center. In total, 220 casual observers (80 untasked, 140 tasked) viewed frontal facial images of women while an infrared eye-tracking monitor recorded their eye movements and fixations in real time. Main Outcomes and Measures Multivariate Hotelling's analysis followed by planned posthypothesis testing was used to compare fixation durations for predefined regions of interest, including the central triangle, upper face, midface, lower face, and neck between tasked and untasked observers. Results A total of 80 observers (mean age 23.6 years, 53% female) successfully completed the first untasked eye-tracking experiment. A total of 140 obsee tracking to investigate facial cues of age. The results showed that when tasked with estimating age, casual observer visual attention was shifted toward the lower face when compared with those who were untasked. These data inform our understanding of facial age perception and potential areas to target for facial rejuvenation. Ralimetinib Level of Evidence NA.Importance Informed consent in rhinoplasty is a challenging process due to the technically demanding surgery with a wide array of potential complications. Objective To underscore the significance of informed consent in rhinoplasty, its complications, and identify gaps in the consent process. Design, Setting, and Participants Dual search and comparison. First a review of the literature for rhinoplasty articles was carried out between January 2000 and November 2017 with at least 100 patients to identify complications and their incidences. Then a comprehensive online search for rhinoplasty consent forms was carried out to identify consent form topics and their incidences. Main Outcomes and Measures Consent form topics and complication rates from the literature review were reported and directly compared. Results A total of 117 articles were included, with 36 different complications reported. Twenty-four consent forms were evaluated, yielding 80 different topics. Common complications within the literature included skin problems such as acne (18.
