Current otolaryngologic applications of the novel self-assembling RADA-16 peptide matrix.

A novel bioresorbable agent on the market is PuraGel® (3-D Matrix, Tokyo, Japan), a RADA-16 product that acts as a synthetic hemostatic and space-filling gel that promotes wound healing and prevents adhesion formation. Given the reported benefits of accelerated wound healing and scar tissue prevention, there are multiple otolaryngologic applications where RADA-16 might improve outcomes. Our study highlights current utilization and associated post-operative complications with this product.

Management of the Nasolacrimal Duct in Expanded Endoscopic Approaches to the Maxillary Sinus: A Systematic Review with Evidence-based Recommendations.

Background: Utilizing expanded endoscopic approaches to the maxillary sinus for the endonasal management of a variety of tumors is increasing in popularity. The nasolacrimal duct (NLD) may be injured inadvertantly or need to be removed during tumor resection or to augment visualization. Management of the NLD can take the form of transection alone, transection with stenting, or performing a formal dacryocystorhinostomy to avoid postoperative sequelae of injury.

Sinonasal Symptom Correlation With the Postoperative Polyp Scale (POPS).

Background: Commonly used endoscopic nasal polyp grading scales have been shown to correlate poorly with symptom scores and quality of life metrics. The recently described Postoperative Polyp Scale (POPS) is a grading system that more accurately characterizes polyp recurrence in postoperative sinus cavities by describing incremental recurrence in relation to the surgically opened sinus cavities.

Objective: The objective of this study was to determine if the POPS correlated with sinonasal symptoms.

Frontal Sinus Anatomy Variations in Race and Sex Using the International Frontal Sinus Anatomy Classification.

To identify frontal sinus anatomical variations grouped by patient sex, race, and presence of chronic rhinosinusitis with frontal sinus involvement (CRFS) using the International Frontal Sinus Anatomy Classification (IFAC) system. A retrospective review from 2015 to 2020 was performed of consecutive adult patients with computed tomography sinus imaging. Prevalence of frontal sinus cells using the IFAC system was recorded.
