so that an inflammatory change is most easily propagated to the bone. The causes of this propagation lie chiefly in the want of free removal of inflammatory products of the mucous membrane: though the membrana tympani be perforated, the tympanic cavity is at the bottom of a long narrow channel, so that stagnation readily occurs; and once inflammation has spread to the bone, the carious and necr...

The development of polypoidal structures, derived from organization of amniotic squamous debris, in the middle-ear cavity of 3 infants is described. The lesions mimicked the development of amnion nodosum lesions of the placenta and were attached to either the tympanic membrane or the head of the stapes. They were accompained by atypical metaplastic changes in the middle-ear epithelium. While th...

Paragangliomas of the head and neck are rare neoplasms presented as cervical mass, generally bilateral, that arise from chemoreceptors located at the carotid bifurcation (carotid body tumors), along the vagus nerve (vagal paragangliomas), and in the jugular fossa and tympanic cavity (jugulotympanic paragangliomas). They are typically asymptomatic at the beginning, highly vascular, slow-growing ...

Unilateral Conductive or Mixed Hearing Loss Unilateral implantable bone conduction (bone-anchored) hearing aid may be considered medically necessary as an alternative to an air-conduction hearing aid in patients 5 years of age and older with a conductive or mixed hearing loss when ONE of the following medical criteria is met:  Congenital or surgically induced malformations (eg, atresia) of the...

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. ...

Herein, we report an unusual case of large tonsillolith presented with acute otalgia. Since the tonsils and tonsillar fossa are supplied by the glossopharyngeal nerve, any irritation or pain can be referred to the ear along the tympanic branch of the glossopharyngeal (Jacobson's) nerve. Also, it is worth re-emphasizing that normal otoscopy must be followed by inspection of the nasal cavities, o...
