The orbital bridge of the nose is the root of the mountain, and a nodule at the root of the mountain may be due to dacryoadenitis, acne, or orbital tumors and other causes. 1. Dacryoadenitis: the lacrimal gland is located in the inner canthus, i.e., the junction of the orbital bridge of the nose. Inflammation of the lacrimal gland, due to the obstruction of the tear duct, may result in enlargement of the lacrimal gland, which is manifested as a nodule in the area of the orbital bridge of the nose. 2. Acne: mainly due to the exuberant secretion of facial sebaceous glands, causing chronic inflammatory disease of facial sebaceous glands, patients will have facial acne, pimples, pustules, seborrhea and other symptoms, and if acne is at the root of the hill, it may look like a nodule when touched. 3. Orbital tumor: a mass formed by over proliferation of organism variant cells located in the orbital region. Orbital tumors are not a common disease and can be asymptomatic in the early stages of tumor development. When the tumor grows to a certain size, it may manifest as a nodule in the orbital nose area. In conclusion, it is recommended that patients go to the hospital for ophthalmologic examination and pathological examination to further clarify the cause of the disease. Treatment should be carried out under the guidance of specialists.
