Nasal vestibular cysts with infection: Nasal vestibular cysts are cysts located under the skin at the bottom of the nasal vestibule and in the superficial soft tissues of the alveolar process of the maxilla. It grows slowly and is asymptomatic in the early stage, but when the cyst grows up, there is a feeling of local swelling. If secondary infection, it will cause swelling and pain, radiating to the head, face and alveolus, resulting in the above situation.
3. rosacea: this disease is a chronic skin damage of the external nose, often accompanied by acne and skin congestion on the tip and wings of the nose, the age of onset is later than that of common acne. Local examination reveals flushing of the external nasal skin, dilated capillaries, papules, pustules or scabs, sometimes accompanied by swelling and hyperplasia of the soft tissues of the nose. If secondary infection can stimulate the trigeminal nerve endings, producing headaches.
