Mucoceles of the paranasal sinuses: uncommon location

Abstract

Mucoceles are the most common lesions causing expansion of the paranasal sinuses. The sinuses most commonly involved are, in decreasing order of frequency, frontal sinus, ethmoid sinuses, maxillary sinus and sphenoid sinus. We reviewed 46 cases of surgically proven mucoceles and the purpose of this study was to report five cases of mucoceles in an uncommon location.

Posttravmatik frontoetmoidal mukopiyosel

“…Although paranasal sinus mucoceles are benign, they may expand into the orbits and cranium by pushing the surrounding bone structures with the pressure they generate in time or by leading to damage in the bone structures with the action of prostaglandin E2 and collagenase enzymes released from the surrounding inflammatory cells (1,4). Paranasal sinus mucoceles cause clinical findings by compressing the surrounding adjacent structures, especially the orbits and cranial or facial structures through expansion.…”

“…Mucoceles that occur as a result of infectious causes or that are infected secondarily are named mucopyoceles (1).…”

“…Nicollas et al (3) reported that mucoceles arose most frequently from the ethmoid sinus in their paranasal sinus mucocele case series, which was composed of 10 pediatric patients. Although mucoceles are benign, they may lead to damage in the surrounding bone structures in time (1,4). Clinical findings including exophthalmos, visual disturbance, and diplopia occur as a result of orbital compression by frontoethmoidal mucoceles (5).…”

Mucucoele of the maxillary sinus and the eye

“…The majority occur in the frontal sinus (60%), followed by ethmoidal sinuses (30%), maxillary sinuses (10%), and rarely the sphenoidal sinuses. 5 The most common cause of mucocoele of the maxillary sinus is trauma: accidental or iatrogenic (Caldwell-Luc procedure). 6 It can also occur in nonHodgkin's lymphoma.…”

“…5 Investigations led to the diagnosis of CVID, and the anterior uveitis responded to topical steroids. It is, however, not clear what happened to the optic disc and choroidal abnormalities.…”
