Laser imaging detection and ranging (LiDAR) is a modern three-dimensional (3D) technology that uses a time-of-flight method based on the round-trip time of an infrared laser beam to detect the presence and features of objects. The iPhone 12 Pro is the first smart mobile device with built-in LiDAR sensors. The authors' team developed a software application based on iOS devices with built-in LiDAR sensors for 3D breast scanning and automatically analyzing the breast's geometric measurement.

Background: Emerging radiation technologies are expected to provide a positive impact on the reduction in postoperative complications in patients receiving prosthetic breast reconstruction. This study aimed to determine whether hypofractionated radiation therapy(RT) with volumetric modulated arc therapy(VMAT) is superior to conventional RT in the setting of prosthetic reconstruction.

Methods: From retrospective data collections, postoperative complications were compared for all patients with mastectomy and staged prosthetic reconstruction without RT, with hypofractionation using 40 Gy in 15 fractions with VMAT (Hypo-VMAT) or conventional RT (50 Gy over 5 weeks).

Progressive fibrosis of the dermal tissues is a challenging complication of radiotherapy whose underlying mechanism is not fully understood, and there are few available treatments. The canonical Wnt/β-catenin signaling pathway plays an important role in fibrosis as well as in the epithelial-to-mesenchymal transition (EMT). We investigated whether inhibition of Wnt/β-catenin signaling with sLRP6E1E2, a molecule that binds to extracellular Wnt ligands, ameliorated radiation-induced fibrosis both in vitro and in vivo.

Background/objective: Volume replacement with the latissimus dorsi (LD) is an option for patients after partial mastectomy. Although potential benefits of using the endoscopic technique have been previously described, previous studies have not assessed long term volume and aesthetic outcomes compared to traditional methods. In this study, we aim to compare the endoscopic, latissimus only harvest to the traditional latissimus with skin paddle method.

Background: Although previous studies have focused on determining prognostic and causative variables associated with fistula-related complications after head and neck reconstructive surgery, only a few studies have addressed preventive measures. Noting that pooled saliva complicates wound healing and precipitates fistula-related complications, we devised a continuous suction system to remove saliva during early postoperative recovery.

Methods: A continuous suction system was implemented in 20 patients after head and neck reconstructive surgery between January 2012 and October 2017.

Background: Radiation-induced skin injury is a dose-limiting complication of radiotherapy. To investigate this problem and to develop a framework for making decisions on treatment and dose prescription, a murine model of radiation-induced skin injury was developed.

Methods: The dorsal skin of the mice was isolated, and irradiation was applied at single doses of 15, 30, and 50 Gy.
