Various devices have been developed to overcome the widespread phenomenon of different degrees of hearing deficits between mild and profound hearing loss. Basically, we differentiate between acoustic stimulation (hearing aids), restricted to cases with a partially functioning cochlear receptor, and electrical stimulation (cochlear implants), stimulating the auditory nerve directly in cases with profound or total hearing loss. For the first time, animal data have been collected that indicate the possibility of nearly interference-free use of both stimulation types simultaneously. In addition, we have gathered the first clinical patient experience, which confirms the encouraging results. Future implications for patients with severe high-frequency hearing loss are discussed.

The purpose of this study was to evaluate whether bacterial biofilms exist on the sinus mucosa surfaces of human subjects with recalcitrant chronic sinusitis. Scanning electron microscopy was used to evaluate patients with continued symptoms of chronic sinusitis despite prior appropriate medical and surgical management. Morphologic structures that confirm the presence of bacterial biofilms were identified on the sinus mucosa of patients infected with <i>Pseudomonas aeruginosa,</i> a known biofilm former. The presence of bacterial biofilms may explain the recalcitrant nature of some forms of chronic sinusitis.

<i>Purpose:</i> To evaluate the outcomes of patients with parapharyngeal space (PPS) tumors treated with a transoral robotic surgery (TORS) approach. <i>Materials and Methods:</i> We prospectively enrolled well-defined benign PPS tumors accessible from the oropharynx with no carotid encasement or bone erosion. We designated outcome measures that included technical feasibility of the approach, local tumor control and complication rates. Descriptive statistics were used to summarize the outcome data. <i>Results:</i> With a mean follow-up of 29.9 months (range 12–40 months), a total of 10 patients have been enrolled. TORS was completed in 9 of 10 patients with acceptable operative time and blood loss and no significant complications including hemorrhage, infection, trismus or tumor spillage. Local control has been 100% for 7 patients with pleomorphic adenomas. <i>Conclusions:</i> We confirm the safety and feasibility of the TORS approach for PPS tumors that achieves a high local control and low surgical complication rate. TORS is a viable approach for removing benign tumors and lesions of the PPS.

We comment on three areas related to tinnitus. The standard of care should include counseling that is collaborative and that addresses the overall emotional well-being of the patient. Utilizing management and coping strategies is desirable. Our new tinnitus activities treatment is an example of such a protocol. We believe that the notions of fearfulness and acceptance have the potential to be integrated into tinnitus treatment. Some patients reject, control or accept their tinnitus. We believe in some instances there may be a common genetic cause of tinnitus and depression. A potential candidate is the serotonin transporter gene <i>SLC6A4</i>.

<i>Objective:</i> We aimed to investigate the efficacy of endoscopic optic nerve decompression in patients with traumatic optic neuropathy. <i>Methods:</i> We performed a retrospective analysis of 46 patients with traumatic optic neuropathy in the Shanghai Eye, Ear, Nose and Throat Hospital between March 2002 and September 2005. All patients were first treated with methylprednisolone for 6 days. Forty-four patients (46 eyes) that did not improve with methylprednisolone treatment were offered endoscopic optic nerve decompression. <i>Results:</i> In 38 eyes with no light perception vision preoperatively, 21 eyes (45.6%) had improvement in visual acuity. These patients had postoperative light perception in 17 eyes, hand movement in 3 eyes and 60/200 in 1 eye. Four of 5 eyes with light perception preoperatively had postoperative vision for hand movement in 2 eyes, finger counting in 1 eye and 20/200 in 1 eye. For 3 eyes with preoperative visual acuity of hand movement, the postoperative visual acuities were 60/200, 60/200 and 120/200. Neither worsening of vision nor major complications was encountered in our series. <i>Conclusions:</i> We conclude that endoscopic optic nerve decompression in experienced surgeons’ hands can improve visual acuity in traumatic optic nerve neuropathy with minimal morbidity. Our results also demonstrate that even patients initially without light perception may benefit from optic nerve decompression.
