Mucous cyst formation after rhinoplasty.

The development of a deforming nasal-dorsal mass after rhinoplasty is a very rare and, for the most part, an avoidable complication. The list of differential diagnoses for such a postoperative external nasal lesion ranges from simple soft tissue edema or hematoma, which is usually temporary, to more serious lesions, such as lipogranulomas, epidermoid inclusion cysts, tumefactive cartilage proliferation, and mucous cysts, which can cause permanent deformities. Although various nasal tumors, infections, and granulomatous diseases are not specifically related to surgery, they should also be considered.
