Congenital Nostril Stenosis with a Horseshoe-like Shape.

We report a rare case of congenital nostril stenosis because it is very interesting from the perspective of human embryo development. As we were not able to find a similar congenital case in the literature, we would like to describe it here. The patient is a 36-year-old woman who had bilateral congenital stenotic nostrils with horseshoe-like shape.

Telementoring Demonstration in Craniofacial Surgery With HoloLens, Skype, and Three-Layer Facial Models.

Background: Telementoring is the technology for providing surgical instruction from a remote place via a network. To demonstrate the use of telementoring in craniofacial surgery, Skype and a mixed reality device HoloLens were adopted, and 3-layer facial models had been developed.

Methods: A resident in hospital A used the model surgery under remote guidance by a mentor surgeon in hospital B 4 times on different dates.

Convenient Synthesis and Physiological Activities of Flavonoids in Coreopsis lanceolata L. Petals and Their Related Compounds.

Chalcones, flavanones, and flavonols, including 8-methoxybutin isolated from Coreopsis lanceolata L. petals, were successfully synthesized with total yields of 2⁻59% from O-methylpyrogallols using the Horner⁻Wadsworth⁻Emmons reaction as a key reaction. Aurones, including leptosidin, were also successfully synthesized with 5⁻36% total yields using the Aldol condensation reaction as a key reaction.
