Mastering Midface Injections.

Injectable filler is one of the most common cosmetic procedures performed annually. An aging face shows a characteristic loss of volume in the deep fat pads of the midface. The goal of midfacial rejuvenation with injectable filler is to restore lost volume, with the suborbicularis fat pad and deep medial cheek fat being the most critical areas. Filler can be instilled here with a cannula or needle with successful outcomes. However, this procedure is not without complications if proper technique and underlying anatomy are not respected.

Anatomical determinants of upper airway collapsibility in obstructive sleep apnea: A systematic review and meta-analysis.

Upper airway (UA) collapsibility is one of the key factors that determine the severity of obstructive sleep apnea (OSA). Interventions for OSA are aimed at reducing UA collapsibility, but selecting the optimal alternative intervention for patients who fail CPAP is challenging because currently no validated method predicts how anatomical changes affect UA collapsibility. The gold standard objective measure of UA collapsibility is the pharyngeal critical pressure (Pcrit). A systematic literature review and meta-analysis were performed to identify the anatomical factors with the strongest correlation with Pcrit. A search using the PRISMA methodology was performed on PubMed for English language scientific papers that correlated Pcrit to anatomic variables and OSA severity as measured by the apnea-hypopnea index (AHI). A total of 29 papers that matched eligibility criteria were included in the quantitative synthesis. The meta-analysis suggested that AHI has only a moderate correlation with Pcrit (estimated Pearson correlation coefficient r = 0.46). The meta-analysis identified four key anatomical variables associated with UA collapsibility, namely hyoid position (r = 0.53), tongue volume (r = 0.51), pharyngeal length (r = 0.50), and waist circumference (r = 0.49). In the future, biomechanical models that quantify the relative importance of these anatomical factors in determining UA collapsibility may help identify the optimal intervention for each patient. Many anatomical and structural factors such as airspace cross-sectional areas, epiglottic collapse, and palatal prolapse have inadequate data and require further research.

The use of race-based terminology in the rhinoplasty literature.

PURPOSE OF REVIEW: To provide an overview of the use of race-based terminology in the rhinoplasty literature. RECENT FINDINGS: The rhinoplasty literature is often indexed by race, with common usage of the terms Ethnic/Non-Caucasian/Nonwhite; African American/of African descent; Hispanic/Latinx; and Asian to refer to certain patient populations. There are wide variations in facial features within these populations, but specific traits may be more prevalent in patients with certain backgrounds. More recently, in particular within the 'Asian rhinoplasty' literature, titles have pivoted to include specific anatomic characteristics of interest, which offers a more objective way of discussing this topic. SUMMARY: The use of race and ethnicity to describe facial and nasal anatomy in the rhinoplasty literature introduces subjectivity and diminishes the validity of the rhinoplasty literature. We advocate the usage of specific physical and anatomic descriptions rather than race and ethnicity within the rhinoplasty literature.

Odontogenic Sinusitis: Current Concepts in Diagnosis and Treatment.

Odontogenic sinusitis is a unique cause of sinus disease that deserves special consideration. An astute clinician can elicit historical findings such as recent dental work, and symptoms such as unilateral facial pain and foul drainage, despite a relatively benign oral cavity examination. Otolaryngologists and dental professionals who care for these patients must be able to interpret imaging studies for dental disorder such as periapical abscesses and periodontal disease. Treatment is frequently some combination of antibiotic therapy, dental procedures, and endoscopic sinus surgery. More prospective studies are needed to determine the best approach to caring for this patient population.
