Destructive Frontonasal Mucocele Following Facial Trauma and Surgery.

Mucoceles are fluid filled cysts with numerous etiologies that can erode bone and if left untreated, can lead to infraorbital and intracranial complications. With limited cases published in the medical literature, our patient with a frontonasal mucocele expanding from the frontal sinus to the nasal dorsum with erosion of the nasal bones and upper lateral cartilages, provides an opportunity for evidence-based diagnosis and treatment. We present a 24-year-old female with a nasal mass destroying numerous nasal structures. Three surgical approaches were considered: open rhinoplasty, bicoronal approach, and Lynch excision; the latter executed with subsequent total nasal reconstruction. Bone, septal cartilage, and temporalis fascia were utilized to provide structural support and a posterior nasal septal flap was incorporated to maintain a blood supply. integrity of nasal structure and cosmesis as well as recurrence of disease were monitored during postoperative visits.
