Mucocele of the Nasal Septum

Complicated Fronto-Orbital Mucopyocele Presenting with Proptosis: Case Report

“…Mucoceles are slow-growing cystic lesions developing secondary to obstruction of the sinus ostium [5]. The etiological factors such as mucosal inflammation of the sinus, nasal polyp, anatomical variations of the nasal cavity, tumors or traumas cause mucocele formation by triggering chronic inflammation of the sinus mucosa [4, 5, 6].…”

“…The etiological factors such as mucosal inflammation of the sinus, nasal polyp, anatomical variations of the nasal cavity, tumors or traumas cause mucocele formation by triggering chronic inflammation of the sinus mucosa [4, 5, 6]. Mucoceles occurring due to cystic dilation of the sinus mucosa and retention of secretion are located in the frontal, maxillary, ethmoid and rarely in the sphenoid sinuses with decreasing rates of prevalence [1].…”

“…Mucoceles account for 4-8.5% of the expanding orbital masses [7]. Mucoceles with orbital involvement generally present with a non-infiltrating mass effect resulting in globe displacement, diplopia, proptosis, lid swelling, palpable mass, ptosis and reduced vision [5, 7]. Frontoethmoidal mucoceles often present with swelling in the superonasal and medial canthal regions, ptosis and inferolateral globe displacement.…”

“…Frontoethmoidal mucoceles often present with swelling in the superonasal and medial canthal regions, ptosis and inferolateral globe displacement. When a mucocele is infected, it is called a mucopyocele [5]. In this case presentation, infected mucocele originating from the frontal sinus extending into the orbital cavity by destroying frontal sinus and orbital roof with resultant symptoms of proptosis and eye pain was presented.…”

“…Mucoceles are treated surgically either with external or endoscopic approaches. Endoscopic approach is recommended in uncomplicated mucoceles due to a low risk of recurrence [5]. However, it is suggested that external approaches will be more convenient in complicated infectious cases extending into the surrounding tissues due to bony destruction [5, 6].…”
