Nasal Epistaxis Balloons: A Comprehensive MAUDE Database Analysis.

Background: While nasal epistaxis balloons are generally seen as safe and routinely utilized by both surgical and nonsurgical providers, the complication profile related to this type of device has not been well defined.

Objective: The objective of this study was to utilize the FDA MAUDE (Manufacturer and User Facility Device Experience) database to better assess adverse events (AE) related to use of nasal epistaxis balloons. Reports were individually tabulated and events were categorized with special attention to AEs.

Eustachian Tube Balloon Dilation: A Comprehensive Analysis of Adverse Events.

Background: Eustachian tube balloon dilation (ETBD) has been Food and Drug Administration (FDA) approved for refractory Eustachian tube dysfunction since 2016. While ETBD is generally seen as safe, the complication profile has not been well defined.

Objective: The objective of this study was to utilize the FDA manufacturer and user facility device experience (MAUDE) database to better assess adverse events (AE) related to ETBD.

Mesoamerican urbanism revisited: Environmental change, adaptation, resilience, persistence, and collapse.

Urban adaptation to climate change is a global challenge requiring a broad response that can be informed by how urban societies in the past responded to environmental shocks. Yet, interdisciplinary efforts to leverage insights from the urban past have been stymied by disciplinary silos and entrenched misconceptions regarding the nature and diversity of premodern human settlements and institutions, especially in the case of prehispanic Mesoamerica. Long recognized as a distinct cultural region, prehispanic Mesoamerica was the setting for one of the world's original urbanization episodes despite the impediments to communication and resource extraction due to the lack of beasts of burden and wheeled transport, and the limited and relatively late use of metal implements.

Utilizing Virtual Surgical Planning and Patient-Specific Cutting Guides in Microtia Repair with Autologous Costal Cartilage Graft.

Virtual surgical planning (VSP) has been applied to many aspects of head and neck reconstruction. The authors describe the use of VSP to create auricular templates in addition to cartilage cutting and suturing guides for microtia repair in 2 patients with unilateral and bilateral grade 3 microtia. Both patients had satisfactory aesthetic results.
