Nine patients had previously undergone prior resection at outside institutions, and four had prior radiotherapy in addition to a prior excision. Transglabellar\/subcranial surgical approach to the anterior skull base was performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>Tumor histology included three World Health Organization (WHO) grade III lesions, one WHO grade II lesion, and 15 WHO grade I lesions. Fourteen patients had evidence of extension into the paranasal sinuses, with the ethmoid sinus being most commonly involved. Kaplan\u2010Meier estimates of mean overall and disease\u2010free survival were 121.45 months and 93.03 months, respectively. The mean follow\u2010up interval was 41.0 months, and at the time of data analysis three patients had recurrent tumors. Seven (36.8%) patients experienced a major complication in the perioperative period; there were no perioperative mortalities. Orbit invasion was observed in four patients, with optic nerve impingement in 11 patients. Of these, three patients had long\u2010term diplopia. No patients experienced worsening of preoperative visual acuity.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p>Olfactory groove meningiomas demonstrate a propensity to spread into the paranasal sinuses, particularly in recurrent cases. Given a tendency for infiltrative recurrence along the skull base, this disease represents an important area of collaboration between neurosurgery and otolaryngology. The subcranial approach offers excellent surgical access for excision, particularly for recurrences that involve the paranasal sinuses and optic apparatus.<\/jats:p><\/jats:sec>","DOI":"10.1002\/lary.22174","type":"journal-article","created":{"date-parts":[[2011,7,20]],"date-time":"2011-07-20T16:14:13Z","timestamp":1311178453000},"page":"2282-2289","source":"Crossref","is-referenced-by-count":25,"title":["Olfactory
