AI Article Synopsis
- A 7-year-old male cat had some serious health problems, including trouble swallowing, coughing, and changes in his eye and voice.
- Doctors used a special medicine that quickly helped some of his symptoms, which indicated that the issue was with a specific part of his nervous system.
- After tests and surgery, they found out the cat had a type of cancer called middle ear adenocarcinoma, leading to problems with important nerves that control his throat and face.
Article Abstract
A 7-year-old castrated male American Shorthair cat presented with left-side Horner's syndrome and voice change. The overall clinical presentation included dysphagia, intermittent coughing, unilateral miosis, and third eyelid protrusion of the left eye. A topical 1% phenylephrine was applied, and miosis and protrusion of the third eyelid disappeared within 20 min which suggested a post-ganglionic lesion. Laryngoscopy showed left-sided laryngeal paralysis. Computed tomography (CT) identified a mass lesion invading outside of the left tympanic bulla with osteolysis. Endoscopically assisted ventral bulla osteotomy was performed for tumor resection and definitive diagnosis. Middle ear adenocarcinoma was diagnosed based on histopathology. It appears that these neurological signs occurred due to adenocarcinoma in the tympanic bulla, penetrating the jugular foramen and the hypoglossal canal and damaging the cranial nerve IX (glossopharyngeal nerve), X (vagus nerve), XI (accessory nerve), and XII (hypoglossal nerve) and the sympathetic nerve. To the best of our knowledge, this is the first case report of Villaret's syndrome associated with middle ear adenocarcinoma affecting the nerves passing through the jugular foramen and hypoglossal canal in cats.

Deep learning multi-classification of middle ear diseases using synthetic tympanic images.
Acta Otolaryngol
January 2025
Department of Otorhinolaryngology, Institute of Science Tokyo, Tokyo, Japan.
Background: Recent advances in artificial intelligence have facilitated the automatic diagnosis of middle ear diseases using endoscopic tympanic membrane imaging.
Aim: We aimed to develop an automated diagnostic system for middle ear diseases by applying deep learning techniques to tympanic membrane images obtained during routine clinical practice.
Material And Methods: To augment the training dataset, we explored the use of generative adversarial networks (GANs) to produce high-quality synthetic tympanic images that were subsequently added to the training data.
Prevalence of High Frequency Noise-Induced Hearing Loss Among Medical Students Using Personalized Listening Devices.

Department of Otorhinolaryngology, Head and Neck Surgery, Bhaarath Medical College, Chennai 600073, Tamil Nadu, India.
The misuse of personalized listening devices (PLDs) resulting in noise-induced hearing loss (NIHL) has become a public health concern, especially among youths, including medical students. The occupational use of PLDs that produce high-intensity sounds amplifies the danger of cochlear deterioration and high-frequency NIHL especially when used in noisy environments. This study aims to evaluate the incidence and trends of NIHL among medical students using PLDs.

Edwin L. Steele Laboratories, Department of Radiation Oncology, Massachusetts General Hospital and Harvard Medical School, Boston, Massachusetts.
Background Introduction: Vestibular schwannoma (VS) tumors typically present with sensorineural hearing loss (SNHL). Losartan has recently demonstrated prevention of tumor-associated SNHL in a mouse model of VS through suppression of inflammatory and pro-fibrotic factors, and the current study investigates this association in humans.
Methods: This is a retrospective study of patients with unilateral VS and hypertension followed with sequential audiometry at a tertiary referral hospital from January 1994 to June 2023.

Department of Otolaryngology, Head and Neck Surgery, General Hospital of Athens "Georgios Gennimatas", Athens, GRC.
Objective: This study aims to present a case of temporal bone (TBP) paraganglioma with an insidious clinical presentation, deviating significantly from the typical hearing loss and pulsatile tinnitus pattern.
Methods: A 70-year-old lady presented to the emergency department with a five-day history of right progressive later cervical swelling extending to the mastoid region and chronic worsening purulent otorrhea. The clinical and radiological findings confirmed the presence of a chronic middle ear process complicated by a Bezold abscess.
