In October 2020, a pair of previously unseen macroscopic glands (tubarial glands) were visualized in the posterior nasopharynx of 100 patients. These glands were not found until now because the region is highly inaccessible . Our objective is to study the structure and sex-based differences of the tubarial glands. An understanding of all salivary glands is critical for improving the quality of life of patients with head and neck cancer.
