This paper mainly explored the application of medical games in doctor-patient communication in pediatric otorhinolaryngology. Taking the "Little Warrior Break Through" medical game service of Shenzhen Longgang District Otolaryngology Hospital as an example, doctors, nurses and social workers formed a multidisciplinary and interdisciplinary team. Focusing on the three major problems in pediatric otorhinolaryngology, namely, the tense doctor-patient relationship, the insufficient doctor-patient communication, and the difficulty of children to cooperate with treatment, the team carried out a series of themed medical games covering the three stages of admission preparation, preoperative counseling, and postoperative rehabilitation for pediatric otolaryngology patients and their families. This paper showed that medical games can effectively help children and their families to ease tension, promote doctor-patient communication, increase the symmetry of doctor-patient information, improve children’s adaptation and acceptance of diseases, and ease the tense doctor-patient relationship. It is hoped that the exploration of the medical game service of "Little Warrior Break Through" will inspire medical social work, and then build micro-operation methods in clinical practice to help construct a harmonious doctor-patient relationship.
