In cases of head trauma, the ear should be evaluated in all of its components. A good understanding of otologic and skull base anatomy enables a thorough trauma assessment of this complex anatomic region. Auricular laceration, abrasion, avulsion, hematoma, frostbite, otitis externa, exostosis, tympanic membrane perforation, ossicular discontinuity, perilymphatic fistula, labyrinthine concussion, temporal bone fracture, facial nerve paresis, and sensorineural hearing loss are a few of the more common otologic injuries seen in active patients...

Nasopharynx (NP) is anatomically difficult to explore adequately. The pharyngeal bursa (PB) is a recess lined with respiratory epithelium along the posterior wall of the nasopharynx between the longus capitis muscles. If the opening through which the bursa drains into the nasopharynx becomes obstructed, a Thornwaldt's cyst (TC) might develop. Small-sized cysts are mostly asymptomatic, whereas large-sized cysts may lead to various nasal and otologic symptoms depending on their localization. In this report, we present a 71-year-old case with a huge TC who presented to our clinic with the complaints of snoring, nasal obstruction, periodic halitosis, postnasal drip, headache, and hearing loss in the left ear and underwent total excision of the cyst through transnasal endoscopy...

The most commonly observed clinical findings in otological practice is discharging ear in which perforation of the tympanic membrane is the commonest, yet the patients hardly ever seek advice for deafness as the presenting symptom. In patients with the symptoms of ear ache or ear discharge when relieved seldom present for follow up and are not very much concerned about the hearing loss present there. There is a different correlation between surface area of tympanic membrane and amplification of sound. Conductive hearing loss is seen in lower tones than higher tones...

Noise-induced hearing loss (NIHL) is a global health problem affecting over 5% of the population worldwide. We have shown previously that acute noise-induced cochlear injury can be ameliorated by administration of drugs acting on adenosine receptors in the inner ear, and a selective A1 adenosine receptor agonist adenosine amine congener (ADAC) has emerged as a potentially effective treatment for cochlear injury and resulting hearing loss. This study investigated pharmacokinetic properties of ADAC in rat perilymph after systemic (intravenous) administration using a newly developed liquid chromatography-tandem mass spectrometry detection method...
