Wanna GB, Sweeney AD, Haynes DS, Carlson ML. Contemporary management of jugular paragangliomas. Otolaryngol Clin North Am . 2015; 48(2):331-341. EBM level 3.........172-182

Summary : This is a well-written, comprehensive review of jugular paragangliomas, discussing epidemiology, clinical presentation, genetics, and management. The extensive experience at the Otology Group of Vanderbilt is discussed. Wise SC, Carlson ML, Tveiten ØV, et al. Surgical salvage of recurrent vestibular schwannoma following prior stereotactic radiosurgery. Laryngoscope . 2016; 126(11):2580-2586. EBM level 3..................................................................................................................................183-189 Summary : This article presents a case-control study of 37 patients who underwent surgical resection of sporadic vestibular schwannoma following failed radiation therapy. Controls were patients who underwent primary microsurgery without having received prior radiation. Complications are reported. At follow up, 73% had satisfactory facial nerve function (HBI-II), which was not different from controls. However, a significantly higher percentage of patients had less-than-complete resection. B.

EBM level 4..................................................................................................................................190-195 Summary : This article examines the long-term facial nerve outcomes after a middle fossa approach for traumatic facial paralysis. Patients with both intact and irreversibly injured facial nerves were included. Using the House-Brackmann facial nerve grading system, facial nerve outcomes are provided at 1 year following surgical intervention, with all patients achieving at least a grade III result. Medina M, Di Lella F, Di Trapani G, et al. Cochlear implantation versus auditory brainstem implantation in bilateral total deafness after head trauma: personal experience and review of the literature. Otol Neurotol . 2014; 35(2):260-270. EBM level 4.........................................196-206 Summary : This article examines hearing outcomes in patients treated with cochlear implants after bilateral temporal bone fractures with hearing loss. Open-set word recognition was obtained in patients undergoing primary cochlear implant placement, and the article identifies the advantage of this technique over auditory brainstem implantation in posttraumatic hearing loss, regardless of fracture location/etiology (with the exception of loss of cochlear nerve continuity).

Schell A, Kitsko D. Audiometric outcomes in pediatric temporal bone trauma. Otolaryngol Head Neck Surg . 2016; 154(1):175-180. EBM level 4.....................................................207-212

Summary : This article reviews the hearing outcomes of pediatric patients who sustained temporal bone fractures during a 13-year period. A distinction between otic capsule–sparing and otic capsule–violating fractures is made, based on CT findings, and this serves as a basis for comparing the observed hearing results. While otic capsule–violating fractures were associated with severe hearing loss, most cases with otic capsule–sparing fractures demonstrated near- normal hearing by 6 weeks post-injury.
