TCB Tokyo Chuo Biyo Geka (Headquarters: Shinjuku-ku, Tokyo; TCB Group Representative: Takeshi Aoki; Advertising Agency/Dissemination: Medical Frontier Inc.), a cosmetic clinic group operating 108 clinics nationwide (as of November 2023, including planned openings), announced that a research paper by Dr. Hiroo Teranishi, TCB General Director, and other TCB doctors, analyzing changes in patient visits and treatment numbers by menu before and after the COVID-19 pandemic, has been published. The paper, titled "Recent Status of Procedures in a Single Nationwide Cosmetic Surgery Group," which summarizes the analysis results using industry-first nationwide cosmetic surgery data in Japan, was published on October 11, 2023 (Wednesday) in the international medical journal "PRS (PLASTIC & RECONSTRUCTIVE SURGERY) global open.

The paper "Recent Status of Procedures in a Single Nationwide Cosmetic Surgery Group" was authored by Dr. Hiroo Teranishi, TCB General Director, along with Dr. Nobuo Yamamoto, Dr. Yumiko Nakagawa, Dr. Mami Sato, Dr. Kimitaka Okumura, Dr. Yoshiko Hondo, and Dr. Masao Saito, all affiliated with TCB Tokyo Chuo Biyo Geka. The paper presents research comparing the increase/decrease in patient visits and treatment numbers by menu, age, occupation, and region at TCB clinics nationwide before and after the COVID-19 pandemic. Until now, there has been no comprehensive data on the current state of cosmetic surgery in Japan, and this publication of analysis results using nationwide cosmetic surgery data is an industry first in the cosmetic medical field.

This paper was published in "PRS (PLASTIC & RECONSTRUCTIVE SURGERY) Global Open," an open-access international journal focusing on global plastic and reconstructive surgery. We believe that publication in such an academic journal will not only help improve the standard of cosmetic medicine in Japan but also contribute to disseminating knowledge and techniques of Japanese cosmetic medicine to the world. As a leading company driving the cosmetic medical industry, TCB will continue to actively publish papers and dedicate itself to improving the standard of cosmetic medicine in Japan.

We compared the increase/decrease in patient visits and treatment numbers by menu, age, occupation, and region between Period 1 and Period 2, before and after the COVID-19 pandemic.

3. Results Age distribution in Period 1 and Period 2 (White histogram: age distribution of all patients; Blue histogram: distribution of patients who underwent under-eye bag removal) The number of procedures in Period 2 (128,898 cases) was overwhelmingly higher than in Period 1 (23,559 cases), resulting in approximately a 5.5-fold increase.
