Prevalence, Severity, Exposures, and Treatment Patterns of Tinnitus in the United States

Importance Tinnitus is a common problem for millions of individuals and can cause substantial negative effects on their quality of life. A large epidemiologic study of tinnitus and its management patterns in the US adult population is lacking. Objectives To quantify the epidemiologic features and effect of tinnitus and to analyze the management of tinnitus in the United States relative to the 2014 American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) clinical practice guidelines. Design, Methods, and Participants This cross-sectional analysis of the representative 2007 National Health Interview Survey (raw data, 75 764 respondents) identified a weighted national sample of adults (age, ≥18 years) who reported tinnitus in the preceding 12 months. Data were collected in November 2014 at the University of California, Irvine, and Harvard Medical School. Main Outcomes and Measures In addition to quantifying prevalence, severity, duration, and regularity of tinnitus, specific data regarding noise exposure and tinnitus management patterns during health care visits were analyzed. Results Among an estimated (SE) 222.1 (3.4) million US adults, 21.4 (3.4) million (9.6% [0.3%]) experienced tinnitus in the past 12 months. Among those who reported tinnitus, 27% had symptoms for longer than 15 years, and 36% had nearly constant symptoms. Higher rates of tinnitus were reported in those with consistent exposure to loud noises at work (odds ratio, 3.3; 95% CI, 2.9-3.7) and during recreational time (odds ratio, 2.6; 95% CI, 2.3-2.9). Years of work-related noise exposure correlated with increasing prevalence of tinnitus (r = 0.13; 95% CI, 0.10-0.16). In terms of subjective severity, 7.2% reported their tinnitus as a big or a very big problem compared with 41.6% who reported it as a small problem. Only 49.4% had discussed their tinnitus with a physician, and medications were the most frequently discussed recommendation (45.4%). Other interventions, such as hearing aids (9.2%), wearable (2.6%) and nonwearable (2.3%) masking devices, and cognitive behavioral therapy (0.2%), were less frequently discussed. Conclusions and Relevance The prevalence of tinnitus in the United States is approximately 1 in 10 adults. Durations of occupational and leisure time noise exposures correlated with rates of tinnitus and are likely targetable risk factors. Management options suggested by the recently published AAO-HNSF guidelines were followed infrequently.

Management of mal de debarquement syndrome as vestibular migraines

Mal de debarquement syndrome (MdDS) is a balance disorder that typically starts after an extended exposure to passive motion, such as a boat or plane ride. Management is typically supportive (e.g. physical therapy), and symptoms that persist beyond 6 months have been described as unlikely to remit. This study was conducted to evaluate the response of patients with MdDS to management with migraine prophylaxis, including lifestyle changes and medical therapy.

Selective Stimulation of Facial Muscles With a Penetrating Electrode Array in the Feline Model

Permanent facial nerve injury is a difficult challenge for both patients and physicians given its potential for debilitating functional, cosmetic, and psychological sequelae. Although current surgical interventions have provided considerable advancements in facial nerve rehabilitation, they often fail to fully address all impairments. We aim to introduce an alternative approach to facial nerve rehabilitation.

Transcanal Micro-Osteotome Only Technique for Excision of Exostoses.

Objectives: To evaluate the outcomes and complications of transcanal excision of exostoses using micro-osteotomes, without a postauricular incision or the use of the drill. Study Design: A retrospective chart review of patients undergoing exostoses excision. Setting: Tertiary Care Medical Center. Subjects and Methods: All of the patients underwent surgical removal of the exostoses using only a 1 or 2 mm micro-osteotomes. Patients were followed postoperatively and associated complications were evaluated. Results: One-hundred thirty-eight ears in 106 patients were treated for obstructive exostosis. The average age of patients was 43 ± 16 years. Of these, 99 were man (93%) and 7 were woman (7%). A majority of the patients (84%, n = 89) had 90 to 100% obstruction of the ear canal. Complete ear canal healing was observed in 80% of patients by 3 weeks. All but one patient had healed by 6 weeks postoperatively. There were 9 (6.5%) slit tympanic membrane perforations that healed with intraoperative gelfoam or fascia myringoplasty. One patient had an anterior canal mobilization which required Xeroform packing for 3 weeks for stabilization. There were no postoperative vertigo, facial paresis, conductive/sensorineural hearing loss, soft tissue stenoses, and no skin grafting required. Conclusions: This is the first study to report a series of patients performing solely a transcanal approach using micro-osteotomes for removing exostoses. Results indicate that it is a safe procedure with low complication rate and expeditious healing. Patients with 100% obstruction can have this procedure performed with no significant increase in morbidity.

Microbiological Sampling of the Forgotten Components of a Flexible Fiberoptic Laryngoscope What Lessons Can We Learn

The effectiveness of a Cidex-based decontamination protocol was analyzed for its effectiveness in cleaning various components of a flexible fiberoptic laryngoscope (FFL), including the handle, eyepiece, and detachable light cable. A random microbiological sampling and aerobic bacterial culture analysis of 6 FFL eyepieces, 6 FFL driver handles, and 5 light cables prior to patient use was performed. Of 17 samples collected, 7 (41%) were contaminated with bacterial organisms. Organisms recovered represented both environmental organisms from skin and oral flora origin. This study demonstrates that potential contaminants may be present on FFL eyepieces and light cables, which are commonly overlooked in the cleaning protocols of a standard otolaryngology clinic.

Dosimetric Analysis of Neural and Vascular Structures in Skull Base Tumors Treated with Stereotactic Radiosurgery

Objective To examine the relationship between the prescribed target dose and the dose to healthy neurovascular structures in patients with vestibular schwannomas treated with stereotactic radiosurgery (SRS). Study Design Case series with chart review. Setting SRS center from 2011 to 2013. Subjects Twenty patients with vestibular schwannomas treated at the center from 2011 to 2013. Methods Twenty patients with vestibular schwannomas were included. The average radiation dose delivered to healthy neurovascular structures (eg, carotid artery, basilar artery, facial nerve, trigeminal nerve, and cochlea) was analyzed. Results Twenty patients with vestibular schwannomas who were treated with fused computed tomography/magnetic resonance imaging–guided SRS were included in the study. The prescribed dose ranged from 10.58 to 17.40 Gy over 1 to 3 hypofractions to cover 95% of the target tumor volume. The mean dose to the carotid artery was 5.66 Gy (95% confidence interval [CI], 4.53-6.80 Gy), anterior inferior cerebellar artery was 8.70 Gy (95% CI, 4.54-12.86 Gy), intratemporal facial nerve was 3.76 Gy (95% CI, 3.04-4.08 Gy), trigeminal nerve was 5.21 Gy (95% CI, 3.31-7.11 Gy), and the cochlea was 8.70 Gy (95% CI, 7.81-9.59 Gy). Conclusions SRS for certain vestibular schwannomas can expose the anterior inferior cerebellar artery (AICA) and carotid artery to radiation doses that can potentially initiate atherosclerotic processes. The higher doses to the AICA and carotid artery correlated with increasing tumor volume. The dose delivered to other structures such as the cochlea and intratemporal facial nerve appears to be lower and much less likely to cause immediate complications when shielded.

Otolaryngological manifestations of Measles (Rubeola): A case report and brief review.

Measles is an acute viral respiratory illness caused by a virus of the Paramyxoviridae family. Despite being eliminated from the United States, small outbreaks across the country continue to occur. The United States experienced a record number of cases in 2014, with 668 cases seen across the country, a record since its elimination in 2000. Here, we present a case of an acute presentation of measles illness and discuss the otolaryngologic manifestation of the disease. Laryngoscope, 126:1481–1483, 2016
