Delayed development of mucocele in the fractured frontal sinus

Strabismus secondary to frontal sinus mucocele associated with nasal polyposis

Paranasal mucoceles are regarded as slow-growing and benign lesions. They are usually recognized by otorhinolaryngologists, but a clinically relevant mucocele with orbital complications may present to an ophthalmologist. We report a 15-year-old's case with unilateral reduced ocular motility due to bilateral frontal mucocele associated with grade II nasal polyposis.

Osteoplasty flap technique for repair of latent (30-year) post-traumatic frontal sinus mucocele: case report and review of the literature

Mucoceles are benign, slow-growing lesions defined as mucus-filled pseudocystic formations. Paranasal mucoceles predominantly affect the frontal sinus (60% to 65%), followed in frequency by the ethmoidal (20% to 30%), maxillary (10%), and sphenoid (2% to 3%) sinuses. Mucoceles usually arise because of sinus ostium obstruction, preceded by infection, fibrosis, inflammation, trauma, surgery or tumors such as osteomas. Mucoceles arising from the frontal sinus present with a variety of clinical signs, including decreased visual acuity, visual field abnormalities, proptosis, ptosis, periorbital swelling, displacement of the globe, restricted ocular movements, and choroidal folds. We describe a case of orbital involvement from a mucocele of the frontal sinus 30 years after the initial trauma, with a review of the published data concerning the etiology, diagnosis, and treatment planning.

Posttraumatic frontal mucocele

Mucoceles of the frontal sinus are expansive cysts filled of the mucus secreted by goblet cells interspersed in the ciliated mucosa. The aim of this article was to present a case of a frontal mucocele that was developed in a 31-year-old man 19 years after having had a frontal sinus fracture. This is a rare entity. Frontal sinus fractures must be treated by a multidisciplinary team to avoid all possible sequelae. An adequate primary management of frontal sinus fractures is essential to prevent complications. This may include conservative attitude, reduction and fixation with miniplates, obliteration, cranialization, or grafting. Removal of any rest of epithelium is mandatory in this sense.
