“…Seven patients had good visual acuity recovery following surgery [3, 4, 6–9]. Of these patients, the time interval between presentation and surgery ranged from a few days [2] to three weeks [9].…”

“…Its clinical significance relates to the relative position of the Onodi cell to the optic nerve. The pathogenesis is thought to be that of direct mechanical compression from the enlarging mucocele causing a subsequent circulatory disturbance with ischaemia resulting in an optic neuropathy [2, 3]. This paper is of optic neuropathy secondary to an Onodi cell mucocele in a young Chinese patient who had complete recovery of visual function following surgical decompression despite a relatively long time interval between the onset of symptoms and surgery.…”

Purpose. To report on a patient with compressive optic neuropathy secondary to an Onodi cell mucocele, who fully recovered visual function following surgery. Method. Case report. Results. A 28-year-old male was admitted with a right visual acuity of 20/100 following treatment for an initial diagnosis of optic neuritis. Subsequent examination suggested compressive optic neuropathy, and neuroimaging confirmed the presence of an Onodi mucocele compressing the optic nerve. The patient underwent a right endonasal sphenoethmoidectomy with decompression 5 weeks after the initial onset of symptoms. Three weeks following surgery, the visual acuity was 20/20, and there was complete resolution of the visual field defect, which has remained stable at 1 year. Conclusion. Onodi cell mucocele should be included in the differential diagnosis of a young patient with compressive optic neuropathy. Surgical decompression should be considered even when symptoms have been present for over a month.

“…However, these findings are nonspecific. Differentiation from a underlying tumor is aided by the addition of MRI examination preoperatively [5]. While it is likely that initially a mucocele would demonstrate a fluid signal in conventional MRI sequences, over time water is resorbed from the collection and the proteinaceous content increases resulting in shortening of T1 relaxation time and characteristic T1 hyperintensity on precontrast sequences [15].…”

“…The discrepancy may be due in part to the fact that older studies using thick section axial CT without isotropic resolution were less sensitive for detecting small air cells which are often flat in configuration within the plane of axial section [4]. Identification of an Onodi cell is of importance prior to sinonasal surgery due to the close anatomic relationship between this posterior air cell and the optic nerve ( [5]; Fig. 1).…”

Aim: The purpose of this study was to analyze the clinical features of patients with posttraumatic paranasal sinus mucocele (PSM). Subjects and Methods: Between 2009 and 2013, we performed endoscopic sinus surgery (ESS) on 68 patients with PSM at the Department of Otolaryngology - Head and Neck Surgery at Hyogo College of Medicine. Five male patients (age range, 45-76 years) with posttraumatic PSM were analyzed retrospectively. Diagnosis was based on the history of injury and radiological findings. Results: Posttraumatic PSM was found in 7% (5/68) of patients. The mean interval from injury to diagnosis was 28.4 years. All patients had frontal sinus mucocele. Four patients had symptoms of headache, diplopia, visual field defect, and forehead swelling, and 1 patient was asymptomatic. ESS was performed under general anesthesia in all cases, and the symptoms improved postoperatively. Reoperation was required in 1 patient (20%) because headache developed with obstruction of the frontal drainage route 7 months after ESS. Conclusions: Posttraumatic PSM was the least frequent form of PSM and was located predominantly in the frontal sinus, causing symptoms long after the forehead injury. The important lessons to be learned for treating posttraumatic PSM are to obtain a detailed history and to enlarge the route to the cyst to avoid its recurrence.
