“…4 The 2 most frequent causes of frontal sinus mucoceles are trauma and inflammatory changes. 1 Obeso et al 5 noted in a retrospective study of 72 patients presenting with paranasal mucoceles that 35% had undergone previous sinus surgery and 14% had had previous facial fractures, suggesting that some mucoceles might be iatrogenic.…”

“…3 The frontal sinus is the most common sinus to be affected by a mucocele, which is generally the result of trauma or inflammatory processes or develops iatrogenically from previous sinus surgery. 1,4,5 Patients with these lesions frequently present with visual complaints secondary to orbital involvement. The visual complaints include diplopia, decreased visual acuity, visual field abnormalities, proptosis, ptosis, periorbital swelling, displacement of the globe and restricted ocular movements.…”

“…The etiology of mucoceles is still a subject of debate in scientific circles and it has not been defined in great detail. It is assumed that the obstruction of the frontal sinus duct and drainage impairment into the middle nasal meatus, as a consequence of a chronic infection, trauma or tumor, represent one of the main causes of their occurrence [2].…”

Introduction/Objective A mucocele is a benign cystic but extremely expansive change in paranasal cavities, first described in literature by Langenbeck in 1820. The etiology of mucoceles is still a subject of debate. It is assumed that the obstruction of the frontal sinus duct and drainage impairment into the middle nasal meatus, as a consequence of a chronic infection, trauma, or tumor, represent one of the main causes of their occurrence. The aim of this study was to describe ophthalmological and clinical properties of frontal sinus mucoceles. Methods Our retrospective study covered a period of 10 years during which seven patients with mucocele in the frontal sinus were operated on. Results Predisposing factors for the appearance of frontal sinus mucoceles were observed in six out of seven patients -the existence of a previous surgical intervention in two patients, the existence of a previous injury in four, and one patient did not exhibit the existence of predisposing factors. Four out of seven mucoceles were located in the rear segments of the frontal sinus. The destruction of the anterior sinus wall was observed in one patient, while the process propagation toward the endocranium and the orbit was present in three out of the seven patients. Postoperative epistaxis was noted in two out of three patients treated with transfacial approaches. Conclusion Transcranial and transfacial approaches are treatment methods for advanced mucoceles with a present intraorbital, intracranial, and endonasal process propagation.

“…Ameloblastoma and odontogenic keratocyst ("keratocystic odontogenic tumor" [KOT]) are two of the more frequent aggressive lesions encountered. 10,11 Diagnosis and Management: After consideration of all the pathologic possibilities, surgical exploration (Figure 3) was undertaken and tissue submitted for histologic examination.…”

“…Treatment is usually surgical, with tumor location, size, and aggressiveness dictating the specific protocol. [8][9][10] Of the odontogenic cysts or tumors that can involve the sinus, the dentigerous cyst is by far the most common. Ameloblastoma and odontogenic keratocyst ("keratocystic odontogenic tumor" [KOT]) are two of the more frequent aggressive lesions encountered.…”
