Canal Dehiscence

AbstractBackground:Underwater endoscopic ear surgery does not require suction and so protects the inner ear from unexpected aeration that may damage its function in the treatment of labyrinthine fistula. A method of underwater endoscopic ear surgery is proposed for the treatment of superior canal dehiscence.Methods:Underwater endoscopic ear surgery was performed for plugging of the superior semicircular canal through the transmastoid approach. Saline solution was infused into the mastoid cavity through an Endo-Scrub Lens Cleaning Sheath. The tip of the inserted endoscope was filled completely with saline water.Results:Using this underwater endoscopic view, the canal was clearly dissected to expose the semicircular canal membranous labyrinth and dehiscence area. No particular complication occurred during the surgical procedure.Conclusion:The underwater endoscopic ear surgery technique for plugging in superior canal dehiscence secures an excellent visual field and protects the inner ear from unexpected aeration.

Horizontal Semicircular Canal

Computerized tomographic (CT) scanning for intracanalicular tumors requires air as a contrast agent within the internal auditory canal and special computer manipulations of the image to visualize small tumors. The same computer manipulations of CT scans provide detail of the middle and inner ear structures not available by non-CT tomographic techniques. The demonstration of horizontal semicircular canal fistula is one area in which CT scanning is clearly superior. Some pitfalls of the technique and interpretation of it will be discussed.

Canal Dehiscence

ABSTRACT The membranous labyrinth is contained within the bony labyrinth and surrounded by perilymph. The only two ‘potentially yielding’ parts of the otherwise solid bony labyrinth are the oval and round windows, which by their relative movements, pressure differentials and resilience are responsible for all the functions attributed to the inner ear. In pathologies, such as trauma, infection or occasionally congenital dehiscence, there may develop a ‘third window’ that may serve as an abnormal communication for the inner ear fluids and manifest with audiovestibular symptoms. Three such distinct entities have been identified, namely ‘superior semicircular canal dehiscence syndrome, perilymphatic fistulae and labyrinthine fistulae’. This overview intends to discuss these above-mentioned entities, as regards their characteristic presentations and principles of management. How to cite this article Hathiram BT, Khattar VS.

Ménière Recognizes That Vertigo Can Originate from the Inner Ear

Benign Course

Prosper Ménière was the first clinician to conclude that vertigo can result from diseases of the inner ear. The symptom of vertigo originally fell under the rubric of apoplectiform cerebral congestion, a disorder thought to result from overfilling of blood vessels in the brain. Ménière noted that patients with vertigo and hearing loss associated with damage to the inner ear often have a benign course, and aggressive treatments such as bleeding can be more dangerous than the underlying disease. The first hint that the semicircular canals may be related to balance rather than hearing was provided by a Frenchman, Marie Jean Pierre Flourens. He systematically cut each semicircular canal in the pigeon and noted that the animal’s head and body tended to move in the plane of the damaged canal. The gyrations of the animals described by Flourens made Ménière think that vertigo in humans might be a similar phenomenon.
