Scale for the assessment of mucosal wave dynamics of the free edges during stroboscopic examination: clinical validation study and analysis of results.

Introduction: Identifying the mucosal wave (MW) is essential when studying the voice; however, its characterization and perceived measurement during laryngeal stroboscopy (LS) are not well defined or standardized because of the subjectivity of its interpretation. This article proposed and validated a scale that characterized and approximated MW measurement during LS, applied it to participants divided into a healthy group and groups with free edge conditions, and identified differences between them.

Methods: This is a descriptive and clinical validation study of the "VASQ (Vertical axis, Anteroposterior axis, Symmetry and Quantity) mucosal wave score" scale based on stroboscopy images of 137 adult men and women divided into a control group and functional and organic pathology groups.

Centripetal endoscopic sinus surgery in chronic rhinosinusitis: a 6-year experience.

Background: Despite technical advances in the tools designed to facilitate endoscopic nasosinusal surgery, the approach used, functional endoscopic sinus surgery, has not undergone major modifications since it was first described in the late 1980s. Centripetal endoscopic sinus surgery (CESS) is a new approach based on taking the medial wall of the orbit and the anterior cranial base as constant dissection landmarks. The aim of this study was to evaluate the long-term outcome of CESS in chronic rhinosinusitis (CRS) by measuring clinical and objective improvement, the need for revision surgery, and the complication rate.
