Multi-Center in-Depth Screening of Neonatal Deafness Genes: Zhejiang, China.

Purpose: The conventional genetic screening for deafness involves 9-20 variants from four genes. This study expands screening to analyze the mutation types and frequency of hereditary deafness genes in Zhejiang, China, and explore the significance of in-depth deafness genetic screening in newborns.

Methods: This was a multi-centre study conducted in 5,120 newborns from 12 major hospitals in the East-West (including mountains and islands) of Zhejiang Province.

[Application of Doppler combined with flap island on monitoring the post-operative blood supply of buried free flap].

Objective: To explore the feasible monitoring techniques for the buried free flap.

Method: Buried free flaps in reconstruction were monitored using combined monitoring techniques in five cases of advanced hypopharyngeal cancer The monitoring effects were analyzed retrospectively.

Result: The operations were carried out successfully and all the five patients got primary healing of incision without vascular crisis.
