A new atmospheric pressure ionization method, plasmaspray ionization, termed as PSI, was developed to be an alternative ambient ion source for mass spectrometry. It comprises a plasma jet device and a sample spray part. While the nonthermal plasma jet strikes the surface of stainless steel tube out of the spray capillary, the sprayed sample will be ionized with the assistant of auxiliary gas.

Article Synopsis
- The study aimed to analyze the blood vessel distribution in expanded skin in the mastoid region to inform the design of flaps for ear reconstruction in cases of congenital microtia.
- The researchers observed blood vessel patterns using a light permeation test and developed different flap designs based on these patterns.
- Results showed that five distinct types of vascular distribution were identified among 403 cases, and all flap designs resulted in complete survival, highlighting the importance of vascular knowledge in flap design.
Objective: To explore surgical procedure for the treatment of acquired ear defect.
Methods: The ear reconstruction was carried out by using soft tissue skin expander and autogenous rib cartilage framework, Medpor framework, auricular prosthesis, and so on.
Results: The long-term follow-ups showed that the flap of reconstructed ear was ruddy, soft, with normal sensory function.
