Otitis media of the left ear was diagnosed by video otoscopic examination in a 7-year-old, intact male Shih-tzu dog (weight, 5.1 kg), that also had three complex ceruminous adenomas and a Pseudomonas aeruginosa infection in the left ear canal. In such cases, total ear canal ablation is usually required. However, a complete cure was achieved in the present case without total ear canal ablation. The complex ceruminous adenomas were excised using a diode laser, and repeated cleansing of the tympanic cavity and ear canal was implemented using a video otoscope. As a result, the ear canal was closed in a U-form, and the otitis media was cured.

: Objective: To discuss therapeutic outcomes in patients with symptomatic near-narrow internal auditory canal (NNIAC). : We retrospectively analyzed the records of 26 symptomatic patients diagnosed with NNIAC, who had been treated with anti-epileptic drugs. In addition to clinical and radiological data, we recorded I-III latencies of auditory brainstem responses prior to and after medical therapy.

Novel therapeutic delivery systems and delivery methods to the inner ear are necessary to treat hearing loss and inner ear disorders. However, numerous barriers exist to therapeutic delivery into the bone-encased and immune-privileged environment of the inner ear and cochlea, which makes treating inner ear disorders challenging. Nanoparticles (NPs) are a type of therapeutic delivery system that can be engineered for multiple purposes, and posterior semicircular canal (PSCC) infusion is a method to directly deposit them into the cochlea.

Objective: To report ocular examination findings before and after total ear canal ablation and lateral bulla osteotomy (TECALBO) and ventral bulla osteotomy (VBO) in cats and dogs.
Methods: At The Ohio State University and MedVet Columbus, ophthalmic examinations were performed on client-owned animals for which a TECALBO or VBO was indicated. Examination findings and postoperative complications relating to ophthalmic and/or neuro-ophthalmic diseases were recorded prior to surgery (T0) and at 1 day (T1), 2 to 3 weeks (T14), and ± 2 months (T60) postoperatively.

Hearing loss is highly related to acoustic injuries and mechanical damage of ear tissues. The mechanical responses of ear tissues are difficult to measure experimentally, especially cochlear hair cells within the organ of Corti (OC) at microscale. Finite element (FE) modeling has become an important tool for simulating acoustic wave transmission and studying cochlear mechanics.

Objective: Acute unilateral peripheral vestibulopathy or vestibular neuritis (AUPV/VN) manifests as acute onset vertigo, often accompanied by nausea, vomiting, and moderate gait instability. It is suspected when vestibular hypofunction is documented on video-head impulse (video-HITs) and caloric tests in the presence of contralesionally beating horizontal-torsional nystagmus. Herein, we report patients presenting with acute vestibular syndrome (AVS) showing selective otolithic dysfunction in the presence of normal caloric and video-HITs and abnormal enhancement of the peripheral vestibular structures on MRI.
