Mucous cysts are very rare complications following rhinoplasty; less than 20 cases have been reported in literature. We present 2 new cases. The first case presented a cyst located beneath the glabella and above the articulation between the spina nasalis and the os nasale. The lesion first appeared 22 months following elective rhinoplasty. The treatment was complete surgical excision using a direct open approach. In the second case, a cyst was indentified between the right inner canthus and the sidewall of the nose. It appeared 6 months following elective rhinoplasty. The treatment was complete surgical excision through a transcartilaginous approach. Both patients had good postoperative results with no evidence of recurrence after a 7- and 8-year follow-up period, respectively. We believe that it is possible to prevent the appearance of mucous cysts after rhinoplasty, with careful dissection and avoidance of dispersion of mucosal material into a subcutaneous plane.
