To review the surgical approaches, techniques, outcomes, and recurrence rates in a series of 6 olfactory groove meningioma (OGM) patients operated from January 2010 to April 2011.Methods: Six patients underwent craniotomy and micro-neurosurgical removal of olfactory groove meningioma maximum. Tumor diameter varied from 5 to 8.5 cm among six cases, 2 cases underwent glabellar mini craniotomy another 2 by bifrontal approach and rest of them were by frontolateral approach. Result: Total removal was possible in all cases. Histopathology revealed typical meningioma (WHO grade 1). there was no operative mortality and no permanent focal neurological deficit except anosmia. One patient developed leak and two cases meningitis which was resolved by lumber drain and antibiotic therapy. No tumor recurrence within six months of followup. For the removal of large olfactory groove meningiomas we used three different surgical approaches: frontolateral approaches, bifrontal approach and glabellar mini craniotomy. We consider the frontolateral approach is an alternative, if not superior, to standard bifrontal approaches. DOI: http://dx.doi.org/10.3329/medtoday.v24i1.13942 Medicine TODAY Vol.24(1) 2012 pp.5-7

Introduction: To review the surgical approaches, techniques, outcomes and recurrence rates in a series of 11 olfactory groove meningioma (OGM) patients operated from January 2010 to April 2019. Methods: Eleven patients underwent craniotomy and micro-neurosurgical removal of olfactory groove meningioma. Tumor diameter varied from 5 to 8.5 cm among 11 cases, 2 cases underwent Transglabellar/ Subcranial approach, 3 cases by bifrontal approach, 1 case unifrontal approach, 2 extended endonasal and 3 cases fronto-lateral approach. Result: Total removal was possible in all cases except 2 cases. Histopathology revealed typical meningioma (WHO grade 1). There was 1 operative mortality and no permanent focal neurological deficit except anosmia. 3 patients developed CSF leak and two cases meningitis which were resolved by lumber drain and antibiotic therapy. Conclusion: Extended endonasal approach or transglabellar/ subcranial approach were sufficient for gross total removal of OGM which is associated with bony hyperostosis, paranasal extension and optic canal.

Abstract OBJECTIVE: To review the surgical approaches, techniques, outcomes, and recurrence rates in a series of 80 olfactory groove meningioma (OGM) patients operated on between 1990 and 2003. METHODS: Eighty patients underwent 81 OGM surgeries. Tumor diameter varied from 2 to 9 cm (average, 4.6 cm). In 35 surgeries (43.2%), the tumor was removed through bifrontal craniotomy; nine operations (11.1%) were performed through a unilateral subfrontal approach; 18 surgeries (22.2%) were performed through a pterional approach; seven surgeries (8.6%) were carried out using a fronto-orbital craniotomy; and 12 procedures (14.8%) were accomplished via a subcranial approach. Nine patients (11.3%) had undergone surgery previously and had recurrent tumor. RESULTS: Total removal was obtained in 72 patients (90.0%); subtotal removal was achieved in 8 patients (10.0%). Two patients, one with total and one with subtotal removal, had atypical (World Health Organization Grade II) meningiomas, whereas 78 patients had World Health Organization Grade I tumors. There was no operative mortality and no new permanent focal neurological deficit besides anosmia. Twenty-five patients (31.3%) experienced surgery-related complications. There were no recurrences in 75 patients (93.8%) 6 to 164 months (mean, 70.8 mo) after surgery. Three patients (3.8%) were lost to follow-up. In two patients (2.5%) with subtotal removal, the residual evidenced growth on computed tomography and/or magnetic resonance imaging 1 year after surgery. One of them had an atypical meningioma. The second, a multiple meningiomata patient, was operated on twice in this series. CONCLUSION: A variety of surgical approaches are used for OGM resection. An approach tailored to the tumor's size, location, and extension, combined with modern microsurgical cranial base techniques, allows full OGM removal with minimal permanent morbidity, excellent neurological outcome, and very low recurrence rates.

Abstract OBJECTIVE Olfactory groove meningiomas account for 8 to 13% of all intracranial meningiomas. Surgical removal is often performed through the bifrontal, unilateral subfrontal (frontolateral), or pterional approach. We report on the clinical outcome and recurrence rate after surgical treatment of olfactory groove meningiomas in our neurosurgical department. METHODS A retrospective study was conducted by analyzing the charts of the patients, including surgical records, discharge letters, histological records, follow-up records, and imaging studies. RESULTS A total of 1800 meningiomas were operated on between 1978 and 2002 in our department. There were 82 patients with olfactory groove meningiomas, including 63 women and 19 men with a mean age of 57.8 years (age range, 33–91 yr). Most patients presented with mental disturbance. Tumors were operated through the bifrontal (n = 46), frontolateral (n = 34), and pterional (n = 2) approaches. Total tumor removal (Simpson Grade 1 or 2) was achieved in most cases (91.2% frontolateral, 93.5% bifrontal). Perioperative mortality was 4.9% (four out of 82 patients, all operated through the bifrontal approach). The overall recurrence rate was 4.9%, with four patients requiring surgery. The mean follow-up period was 63.4 months (range, 4–270 mo). CONCLUSION Olfactory groove meningiomas were removed mainly through two different surgical approaches. Even in large tumors, high rates of total tumor resection could also be achieved with low recurrence rates using the simple and minimally invasive frontolateral approach. In recent years, we have preferred to use the frontolateral approach, which provides quick access to the tumor with less brain exposure while still enabling total tumor removal with a low morbidity rate and no mortality.

Abstract Background Meningiomas are usually benign tumors and account for 15% of the overall intracranial tumors. Less than 3% of them extend up to the sinonasal region. Case Report A 61-year-old woman, operated on for a huge olfactory meningioma 8 years before, came for progressive nasal obstruction. On physical examination, a mass that completely obliterated the right nasal passage was detected. A c.e. cranial MRI confirmed the presence of an enhancing mass completely occupying the right nostril, without intracranial extension. A biopsy of the mass revealed a meningioma (WHO grade I) and the patient was admitted to our department for the surgical removal of the endonasal recurrent tumor. Results The meningioma was approached and excised by endonasal endoscopic approach using a microdebrider and electrocautery. A linear residual of tumor was left attached to the previous anterior skull base’ vascularized galeal flap, in order to avoid a communication with the intracranial compartment and a possible cerebrospinal fluid (CSF) leak. The postoperative course was uneventful, and the patient immediately referred an improvement in breathing. A c.e. postoperative MRI confirmed the nearly total removal of tumor. Conclusions We present a video with the most relevant steps of transnasal endoscopic surgical removal of a quite rare case of a recurrent olfactory groove meningioma, completely obliterating the right nostril.

We present a 69-year-old transgender woman who underwent gender-affirming surgery in 1998 and gender-affirming hormone therapy (cyproterone acetate (CPA) and estradiol) since this time. Following an MRI scan to investigate tremor in 2013, an incidental left anterior clinoid and right petrous meningioma were identified. Subtotal surgical resection was achieved for the anterior clinoid meningioma (WHO grade 1, meningothelial subtype). At follow-up in 2016, an olfactory groove meningioma and left greater wing of sphenoid meningioma were identified. By 2017, both tumours, along with the petrous meningioma, demonstrated significant growth. In 2018, clinical decline was evident and MRI demonstrated further tumour growth. Surgery was scheduled and the olfactory groove meningioma was completely resected (WHO grade 2, chordoid subtype). Hormones were stopped, after which regression of the petrous meningioma was observed. This case demonstrates an association between high-dose CPA and estradiol and the development, growth and regression of meningiomas in a transgender woman.

Memory Disturbance

Introduction: Meningiomas are the third most common intracranial tumors in adults after glial tumors and metastases. Olfactory groove meningiomas often grow without symptoms due to their slow growth rates and location in the frontal lobe. Optic nerve sheath meningiomas are benign neoplasms of the meninges surrounding the optic nerve. The coexistence of olfactory groove and optic nerve sheath meningiomas without any history of neurofibromatosis or radiotherapy has never been reported in the literature. Case Report: A 36-year-old female patient presenting with anosmia, headache, memory disturbance, and visual impairment and operated with the diagnosis of olfactory groove meningioma was reported. In the postoperative period, optic nerve sheath meningioma was detected in the imaging performed due to the persistence of visual impairment. Conclusion: Olfactory groove and optic nerve sheath meningiomas are rare tumors and can be diagnosed late because they progress slowly. Early diagnosis and treatment may affect the prognosis and morbidity of these patients favorably.
