RESUMEN
BACKGROUND: Cochlear implantation has been used to rehabilitate profoundly deafened adults for more than 25 years. However, surgical labyrinthectomy is often considered a contraindication to cochlear implantation, especially if there is a significant delay between the two procedures. As the role of cochlear implantation continues to expand, this idea requires reconsideration. CASE REPORT: A 59-year-old woman presented to our clinic after undergoing bilateral surgical labyrinthectomies for intractable Ménière's disease 21 years prior. Despite the significant time delay, she underwent cochlear implantation with a good audiological outcome and improved quality of life. CONCLUSION: Changes to the cochlea and vestibule following surgical labyrinthectomy include cochlear ossification and obliteration of the vestibule. These issues have been thought to limit the potential for cochlear implantation, especially when there is a significant delay between the two procedures. However, delayed cochlear implantation, even decades after labyrinthectomy, remains a viable treatment option which can benefit selected patients.

OBJECTIVE: To present a case of extraskeletal Ewing's sarcoma originating in the masseter muscle, and to review the diagnosis and management of these rare tumours. METHODS: Case report and literature review. RESULTS: We report a patient with Ewing's sarcoma of the masseter muscle with mandibular invasion. She was treated with induction chemotherapy, salvage surgery and free flap reconstruction. CONCLUSION: This case highlights the management of these rare tumours. Aggressive multi-modal treatment, including multi-agent chemotherapy, surgical resection and irradiation, appears to offer the best prognosis. Contemporary reconstructive techniques can restore function and form in cases with challenging defects.
