We discuss a case of complete hearing recovery after resection of a jugular foramen schwannoma (JFS) in a patient who also had a small intracanalicular vestibular schwannoma (VS).<\/jats:p><jats:p>\n          Case\u2003A 46-year-old woman presented with left ear fullness, tinnitus, and imbalance for 9 months. She had no lower cranial nerve dysfunction. Audiometry demonstrated Class D hearing with 4% word recognition on the left. Vestibular testing showed absent caloric response on the left and subtle central findings. Magnetic resonance imaging demonstrated a left 3.3-cm JFS and separate left 1-cm intracanalicular VS. A retrosigmoid approach was performed for a radical subtotal resection of the JFS, relieving the mass effect on the vestibulocochlear nerve. The small intracanalicular VS was not manipulated. Pathology confirmed schwannoma with neurofibromatosis type 2 (NF2) mutation in the tumor but normal NF2 germline. Postoperative audiometry at 6 weeks showed normal audiometric thresholds with 100% discrimination. Subtle left caloric response was noted on postoperative vestibular testing and central oculomotor findings improved.<\/jats:p><jats:p>\n          Discussion\u2003The presented case describes the management of concurrent ipsilateral VS and JFS in the absence of NF2 and demonstrates a unique complete and rapid recovery of hearing following JFS resection without manipulation of concurrent VS. This case supports the use of a hearing-preservation approach in similar cases and corroborates previous reports of hearing recovery following resection of non-VS CPA tumors with hearing-preservation approaches.<\/jats:p>","DOI":"10.1055\/a-2516-7311","type":"journal-article","created":{"date-parts":[[2025,1,16]],"date-time":"2025-01-16T00:01:06Z","timestamp":1736985666000},"page":"e24-e30","source":"Crossref","is-referenced-by-count":0,"title":["Complete
