Also, with mobile apps, updates and events can be announced with push notications, or in­app messages instead of repetitive emails, which often are automatically ltered into “Junk Mail” and are thus never seen or read by the user. As mobile apps can track and observe user engage­ment, they can provide the user with custom rec-

The original procedure can be performed with all the aforementioned recording equipment, without concerns of affecting patient­centered outcomes of surgery. Furthermore, the procedure can be performed at the usual pace of the surgeon without any need for time constraints. Intraoperative adverse events can also be man­aged, recorded, and subsequently used as an edu­cational tool for members of the audience. Additionally, the high-quality recording and the multiple intraoperative vantage points allow the surgeon to pause, zoom in, and focus on specic parts of the procedure of particular interest to the audience, while being able to switch between the various views in the operating room (Fig.46.10). This technique also allows the surgeon to narrate various specics to the audience, without the concern of loss of intraoperative focus or atten­tion during otherwise critical steps of the proce­dure (the time when questions tend to most commonly be asked during non-deferred live sur-
