Submandibular gland is an important
human function organ. With the wide application of sialoendoscope and new
understanding of
IgG4 related
sialadenitis, a lot of
submandibular glands which were previously considered to be removed are preserved. However, some
submandibular glands which might be preserved are still unfortunately sacrificed. Therefore, we advocate the popularization and promotion of new
knowledge and
techniques and should pay more
attention to the
protection of the function organ of
submandibular gland.
