Day surgery is still a new practice in China, accounting for only 5% of EENT operations, compared 70% in Europe and the US. TreeENT looks to fill the market gap with cutting-edge medical device and by offering personalised treatment plans with medical experts. The development of day surgery is supported by the Chinese government.

TreeENT opened its first day surgery centre in Hangzhou, Zhejiang Province in July 2017. As of the end of 2018, TreeENT had already served nearly 100,000 patients.
