Dynamic navigation systems were introduced to facilitate dental implantology by improving the accuracy of dental implant positioning. Dynamic navigation integrates surgical instrumentation and radiologic images by using an optical positioning device controlled by a dedicated computerized interface. These features could help in reducing the risk of unintentional iatrogenic damage to nearby anatomic structures and perform minimally invasive or flapless surgery, leading to reduced patient postoperative discomfort and improved healing.

The surgical injury of the intracranial portion of the facial nerve (FN) is a severe complication of many skull base procedures, and it represents a relevant issue in terms of patients’ discomfort, social interactions, risk for depression, and social costs. The aim of this study was to investigate the surgical and functional outcomes of the most common facial nerve rehabilitation techniques. The present study is a systematic review of the pertinent literature, according to the PRISMA guidelines.

Background?Bowel flaps are a good and reliable method to restore the continuity of the aerodigestive tract. Radiated fields, contaminated recipient sites, or depleted recipient vessels may increase the risk for ischemic injury after transfer. During ischemic events, we believe that bowel conduits with serosa have a delayed neovascularization process at its new recipient site.

We conducted an ischemia/reperfusion murine model to understand the difference among bowel conduits with and without serosa.

BACKGROUND:

OBJECTIVE:

Background: Homodigital adipofascial flap is a well-established method for treating a distal fingertip defect; nonetheless, its use has some limitations. Reconstruction of fingertip injuries, with
radial or ulnar tissue loss, may lead to some difficulties in providing an adequate bone coverage.
The standard bipedicled technique did not allow the flap to cover the bone exposure without
excessive tension. In our series, the reverse adipofascial flap had a single pedicle. The modified

BACKGROUND:
In a vessel-depleted neck, distant recipient sites may be the only option for secondary free flap reconstruction. While interposition vein grafts and arteriovenous loops can bridge the gap between the recipient and donor pedicle, they are not without risks. In these scenarios, we examinate the reliablity of a radial forearm free flap (RFFF) as an alternative vascular conduit.
