The persistent stapedial artery (PSA) is an exceedingly vascular anomaly that can lead to hearing loss or pulsatile tinnitus, yet its preoperative diagnosis is often challenging. We report the case of a 24-year-old woman with bilateral PSA and stapes ankylosis who presented with progressive bilateral mixed hearing loss. The patient was initially diagnosed with bilateral congenital stapes ankylosis and stapes surgery was performed on the left side using transcanal endoscopic ear surgery (TEES).

Large vestibular aqueduct syndrome (LVAS) is a congenital malformation characterized by an abnormally large vestibular aqueduct, diagnosed primarily via CT scans. Patients with LVAS often experience progressive hearing loss and recurrent vertigo, with treatment strategies mirroring those for Meniere's disease. Traditional surgical interventions such as endolymphatic sac decompression (ESD) are common; however, the efficacy of endolymphatic duct blockage (EDB) as an alternative still remains under investigation.

Cogan's syndrome is characterized by ocular symptoms and auditory vestibular dysfunction. Auditory vestibular dysfunction in Cogan's syndrome is believed to be similar to Ménière's disease, but the cause is not known in detail. We present the case of a 10-year-old boy with Cogan's syndrome.

Objective: Adults over the age of 65 years with balance disorders are at about twice the risk of falls, compared with those without balance disorders. Falls contribute to about 74% of the proximal femoral fractures commonly seen in the elderly. Since balance disorders are more prevalent in older adults than in younger adults, it is important to deal with balance disorders in older adults to prevent falls and the resulting deterioration in their ADL (activity of daily living).

Propylthiouracil (PTU)-induced otitis media with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (OMAAV) is an extremely rare adverse event associated with anti-thyroid drugs and is not well recognized. A 42-year-old woman with Graves' disease undergoing PTU therapy for 8 years visited our hospital because of earache and congested feeling in her left ear. Blood tests, a computed tomography scan and pure tone audiometry revealed otitis media and moderate mixed hearing impairment.

Puncture drainage is usually needed to treat peritonsillar abscess. However, inadvertent carotid artery puncture may result in devastating complications. Preoperative transoral carotid ultrasonography (TOCU) is useful to delineate the anatomical relationship between the abscess and carotid artery.
