Variants in the unconventional myosin gene, MYO1A, have been reported to cause non-syndromic sensorineural hearing loss with a pattern of autosomal dominant inheritance. Others have challenged this association. We used a genotypic ascertainment study design to test the association of MYO1A variants with hearing loss. We evaluated MYO1A variants from a cohort of 951 individuals with exome sequencing who were not ascertained for hearing loss. Five individuals had one of two variants claimed to be associated with sensorineural hearing loss in a prior study and 33 individuals had one of 13 predicted deleterious variants...

Cone beam computed tomography (CBCT, syn. digital volume tomography = DVT) was introduced into ENT imaging more than 10 years ago. The main focus was on imaging of the paranasal sinuses and traumatology of the mid face. In recent years, it has also been used in imaging of chronic ear diseases (especially in visualizing middle and inner ear implants), but an exact description of the advantages and limitations of visualizing precise anatomy in a relevant number of patients is still missing. The data sets of CBCT imaging of the middle and inner ear of 204 patients were analyzed regarding the visualization of 18 different anatomic structures...

Microtia reconstruction is a challenging endeavor that has seen significant technique evolution. It is important to educate patients and their families to determine the best hearing rehabilitation and ear reconstructive options. Microtia is often associated with aural atresia, hearing loss, and craniofacial syndromes. Optimal care is provided by multiple disciplines, including a reconstructive surgeon, an otologic surgeon, an audiologist, and a craniofacial pediatrician. Microtia management includes observation, prosthetic ear, autologous cartilage reconstruction, or alloplastic implant placement...

Dizziness and vertigo are among the most common symptoms to bring a patient to a neurologist. Because symptoms are often vague and imprecise, a systematic approach is essential. By categorizing vestibular disorders based on timing, triggers, and duration, as well as through focused oculomotor and vestibular examinations, the vast majority of neuro-otologic diagnoses can be made at the bedside. Here the authors discuss historical and examination pearls for the most common neuro-otologic disorders.

Acute otitis externa (AOE) is an infection of the external auditory canal, the auricle, and the outer surface of the tympanic membrane. Although AOE is one of the most common otologic conditions encountered in pediatric population, it is known to primarily affect children older than 2 years. We report a case of AOE caused by Staphylococcus aureus in a 23-day-old neonate. A 23-day-old female infant presented to our neonatology clinic with irritability and discharge from the right ear. There were yellow otorrhea, mild erythema, and edema of right external ear canal...

Treating tinnitus with the resources offered in hospitals can become necessary for patients suffering from complex tinnitus if a high symptom severity, usually accompanied by a corresponding psychosomatic comorbidity, is present. For such costly therapies, for example, the neuro-otologic psychosomatic tinnitus therapy (NPT) examined here, the long-term effect is particularly important; however, reliable catamnesis studies for inpatient treatments are not yet available. Data from 169 (from a total of 327 contacted) inpatients suffering from complex tinnitus were analysed here...

BACKGROUND: The degree to which different sinonasal symptoms contribute to the overall quality of life (QOL) detriment in chronic rhinosinusitis (CRS) patients remains unknown. In this study we sought to characterize the effect of different CRS symptoms on the general health-related QOL in patients. METHODOLOGY: We performed a prospective cross-sectional study of 131 adult patients with CRS. Sinonasal symptoms were evaluated using the 22-item Sinonasal Outcomes Test (SNOT-22) and general health-related QOL was evaluated using the EuroQol 5-Dimensional general health-related QOL survey (EQ5D) and visual analog scale (EQ5D-VAS)...

In the maxillofacial area, osteomyelitis generally involves the mandible more commonly than the maxilla. Osteomyelitis of the mandible more often than not is odontogenic in origin and the dentate part is usually affected. In this context, involvement of the condyle and coronoid processes is very rare. This report describes 2 unique cases of condylar involvement with osteomyelitis. In these cases, the etiologies were unknown and were successfully managed by condylectomy and antibiotics. A comprehensive review of the English-language literature showed only 18 cases of osteomyelitis of the condyle...

BACKGROUND: The clinical polymorphism of syphilis leads to diagnostic issues. We report a case of secondary syphilis revealed by skin and mucosal erosions, and responsible for sensorineural hearing loss and asymptomatic papillitis. PATIENTS AND METHODS: A 55-year-old man presented oral and peri-anal erosions as the initial symptoms of secondary syphilis. He reported hypoacusis and a pure-tone audiogram revealed bilateral sensorineural hearing loss. Ophthalmological investigation revealed isolated right papillitis and superior temporal scotoma with blind-spot enlargement...

This chapter will focus on vertigo/dizziness due to inner-ear malformations, labyrinthine fistula, otosclerosis, infectious processes, and autoimmune inner-ear disorders. Inner-ear malformation due to dehiscence of the superior semicircular canal is the most recently described inner-ear malformation. Vertigo/dizziness is typically induced by sound and pressure stimuli and can be associated with auditory symptoms (conductive or mixed hearing loss). Labyrinthine fistula, except after surgery for otosclerosis, in the context of trauma or chronic otitis media with cholesteatoma, still remains a challenging disorder due to multiple uncertainties regarding diagnostic and management strategies...

In most dizzy patients a limited selection of bedside tests, together with the history, is adequate to establish a differential diagnosis and select the next diagnostic and therapeutic procedures. A set of basic bedside tests that should be applied in every patient with vertigo or imbalance allows identifying: (1) patients who need immediate referral for further assessment and treatment; (2) patients with nonthreatening disorders for which treatment can be started without more detailed testing; (3) patients with benign paroxysmal vertigo, in whom a detailed work-up is not required and who can immediately be treated with an appropriate particle-repositioning maneuver; and (4) patients who need a comprehensive neuro-otologic and neurologic work-up...

HYPOTHESIS: At present there are no serum biomarkers available to monitor cochlear health in those at risk of hearing loss. Outer hair cells (OHCs) play an important role in cochlear function and are one of the cellular elements most vulnerable to damage, such as acoustic trauma. We hypothesized that an OHC-specific protein can serve as a biomarker for OHC damage in circulation. METHODS: After assessing auditory function, rats were exposed to intense octave band noise for 2 to 3 hours...

The mammalian cochlea has historically resisted attempts at high-resolution, non-invasive imaging due to its small size, complex three-dimensional structure, and embedded location within the temporal bone. As a result, little is known about the relationship between an individual's cochlear pathology and hearing function, and otologists must rely on physiological testing and imaging methods that offer limited resolution to obtain information about the inner ear prior to performing surgery. Micro-optical coherence tomography (μOCT) is a non-invasive, low-coherence interferometric imaging technique capable of resolving cellular-level anatomic structures...
