HYPOTHESIS: SENS-401, an oral clinical-stage drug, may reduce cisplatin-induced hearing loss and cochlear damage in an in vivo model. BACKGROUND: Cisplatin is commonly associated with hearing loss, causing significant learning and behavioral difficulties in the pediatric cancer population, and for which there are currently no clinical solutions. SENS-401 has previously been shown to improve acoustic trauma-induced hearing loss in vivo. METHODS: The effect of SENS-401 (R-azasetron besylate) on cisplatin IC50 values was evaluated in a panel of cisplatin-sensitive cell lines (NIH:OVCAR-3, SK-N-AS, NCI-H460, FaDu)...

OBJECTIVE: The increasing use of primary gamma-knife radiosurgery (GKS) for the treatment of vestibular schwannoma (VS) has led to a concomitant increase in the number of patients requiring salvage surgery for GKS failure. When patients underwent GKS as the primary treatment, it is known that dissecting tumor from adjacent nerves during salvage surgery is more difficult. In this report, we share our clinical experience with such patients and analyze the clinical findings of patients with tumor regrowth/recurrence...

HYPOTHESIS: The suprameatal crest and temporal line provides a reliable landmark to the middle fossa dura. BACKGROUND: Surface anatomy of the temporal bone is used to guide mastoid surgery, but studies investigating these landmarks are limited. The aim of this study was to examine the anatomical relationship of the middle fossa dura to the temporal line. METHODS: Thirty-two fresh hemicephalic temporal bones were prepared by drawing four lines along the mastoid including the suprameatal crest and temporal line (line 2), one line 5 mm superior to line 2 (line 1), and one 5 mm inferior to line 2 (line 3), and at Reid's base line (line 4)...

Kyung Jin Roh, Sera Park, Jin Se Jung, In Seok Moon, Sung Huhn Kim, Mi Young Bang, Jae Young Choi
BACKGROUND AND OBJECTIVES: Patients with SCL26A4 mutations presenting with Mondini deformity and enlarged vestibular aqueduct (EVA) tend to have comparable residual hearing. Although cochlear implantation (CI) produces good results in this group, deterioration of residual hearing can be an adverse event after surgery due to accompanying cochlear malformation and perilymph leakage during cochleostomy. The purpose of this study was to investigate if CI in patients with SCL26A4 mutations via the round window (RW) approach could achieve preservation of residual hearing, and to evaluate their speech reception with electroacoustic stimulation (EAS)...

HYPOTHESIS: To explore the results of a new slim modiolar electrode array (SMA) with respect to intracochlear placement and trauma evaluated by detailed radiologic imaging and histology. BACKGROUND: Hearing and structure preservation is the goal of cochlear implantation for advanced hearing outcomes. Currently, this is most consistently achieved with thin lateral wall electrodes. Modiolar electrodes are located nearer the modiolus and may provide some electrophysiological advantages, but have a greater tendency for causing insertion trauma...

OBJECTIVE: Adenocarcinoma of the middle ear is a rare entity that must be distinguished from other adenomatous tumors of the temporal bone. We present the first patient of an intestinal-type adenocarcinoma originating from the middle ear. PATIENTS: A 58-year-old woman presented with an 8-year history of left otorrhea. Her middle ear effusions were quite thick and gummy. She underwent eight sets of pressure-equalization tubes within 3 years. In 2011, her physical examination identified a middle ear mass, and she underwent mastoidectomy...

OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) is characterized by recurrent episodes of positional vertigo due to dislodged otoconia debris within the semicircular canals. Many studies have proposed a correlation between Vitamin-D deficiency and recurrent BPPV. In the UK, serum Vitamin-D falls during the winter, reaching its lowest level in May and it is highest level in September. We hypothesize that if there is a relationship between BPPV and Vitamin-D levels, one would expect to see a seasonal variation in the incidence of BPPV among UK residents...

OBJECTIVE: CHARGE syndrome is associated with a variety of temporal bone anomalies and deafness. The lack of surgical landmarks and facial nerve irregularities make cochlear implantation in this population a challenging endeavor. This study aims to describe a safe and efficacious transcanal approach for cochlear implantation that obviates the need to perform a mastoidectomy and facial recess. PATIENTS: Three children with profound hearing loss secondary to CHARGE syndrome...

Matthew L Carlson, James Bradley, Jamie J Van Gompel, R Shane Tubbs
BACKGROUND: The first description of the voluntary motor function of the facial nerve and separate sensory-motor contributions of the trigeminal nerve is most commonly attributed to Charles Bell. However, a review of the original scientific accounts and subsequent historical publications question the validity of this credit. The objective of the present historical analysis is to clarify the contributions of Herbert Mayo toward discovering the functions of the fifth and seventh cranial nerves and to raise awareness of this historical controversy within the medical literature...
