Sinus surgery simulation has proven to be a valuable teaching tool, yet the cost of many simulators limits the incorporation of this technology into training programs. The authors developed an inexpensive endoscopic sinus surgery task trainer and evaluated its value as a means of developing basic endoscopy and sinus surgery skills. For less than 5 US dollars, the training model was constructed using gelatin and embedded with reusable, recyclable, and readily available materials. Ten attending otolaryngologists performed nasal endoscopy and 5 specific tasks using this model, followed by completion of a survey evaluating the value of the model as a teaching tool. The model scored very well in promoting camera skills, instrumentation, and hand-eye coordination. This easily reproducible, highly rated sinus surgery task trainer can serve as an alternative to more expensive simulators. Studies are under way to determine its validity and effectiveness as both a teaching and assessment tool.

This study explores evolved Hyaluronidase, Lipase, and Elastase's identification, characterization, and therapeutic potential to enhance tissue regeneration and drug delivery systems in otolaryngology. Hyaluronidase variant H5 exhibited a turnover number (k_cat) of 1500 min, a 200 % increase over wild-type (500 min), demonstrating superior hyaluronic acid degradation. Similarly, lipase variant L2 reached 1200 min (400 min wild-type), and elastase variant E3 showed a turnover of 2200 min (1000 min wild-type).

Aortic regurgitation is a common valve disease and can be caused by delineated findings such as fenestrations or hardly discernible alterations of the aortic root geometry. Therefore, aortic regurgitation can be a challenging diagnosis during an autopsy. Cardiac surgeons, however, are confronted with comparable problems during surgery and have developed a refined knowledge of the anatomy of the aortic root including its geometry.

Pterygomaxillary separation (PMS) is an important step in Le Fort I osteotomy procedure, without which complete mobilization of the maxilla cannot be achieved. The aim of this study was to evaluate PMS patterns and their relationship with the anatomic measurements in Le Fort I osteotomy. In this prospective observational study cone beam computed tomography (CBCT) was used to measure the anatomic variables of the pterygomaxillary junction (PMJ) region including thickness, width, the distance between the most concave point at the lateral surface of PMJ and the greater palatine foramen (C-GPF), and the angle preoperatively, and the separation patterns postoperatively divided into the clean-cut type, maxillary sinus type, and the pterygoid fracture type.

Background/aim: Eosinophilic granulomatosis with polyangiitis (EGPA) is a multisystemic disease associated with nasal polyposis. Multiple biologics are used for managing EGPA, including some approved for nasal polyps (NP). This study investigated real-world biologic prescription patterns for EGPA and their impact on NP and endoscopic sinus surgery (ESS) use.

Bilateral preseptal cellulitis without accompanying sinusitis or skin trauma is uncommon. In this report, we present a case of bilateral preseptal cellulitis and an upper eyelid abscess in an otherwise healthy child. A nine-year-old girl presented with severe and progressive bilateral swelling of the upper lids that showed an unsatisfactory response to medical treatments (intravenous ceftazidime and vancomycin) and warranted a referral to our facility.
