- Abstract
Esthesioneuroblastoma (ENB) involving the anterior skull base is a rare malignant tumour derived from the olfactory epithelium. The gold standard of surgical treatment is currently craniofacial resection (CFR), which allows efficient removal of the tumour but entails significant morbidity. To reduce morbidity combined with good visualization of tumour limits removal, endonasal endoscopy resection (EER) has developed. The objective of this work was (1) to describe the EER surgical procedure, the morbidity, and the limitations of this endoscopic approach as compared with CFR, (2) analyse recurrences to define risk factors of recurrences and (3) to discuss a therapeutic decision algorithm. Retrospective series of 18 patients with ENB endoscopically treated in a university tertiary referral centre over 13 years. Fifteen of those underwent radiotherapy. Epidemiological data, clinical and imaging findings, histology, treatment modalities and outcome of patients were studied. Mean follow-up was 31 months. Morbidity was mainly related to radiotherapy. Three recurrences were detected: one bone and one sylvian metastasis, and a local recurrence in a patient not irradiated. One recurrence spread through leptomeningeal propagation. Dural extension and frontal invasion were significantly associated with recurrences ( p = 0.001 and p = 0.019, respectively). Patients with dural extension or frontal invasion should receive aggressive treatment. With a low rate of perioperative morbidity and efficient local control, EER seems to be a promising approach for selected cases of ENB.
