Lateral Semicircular Canal Dehiscence
Otology & Neurotology, 2007genesis of these symptoms has been attributed to the presence of a third window, which provides a different path for the dissipation of acoustic energy (4). A subset of patients, however, are asymptomatic, and these patients’ conditions are diagnosed on imaging or postmortem analyses of temporal bones.

The Dimensions and Sensitivities of Semicircular Canals
Journal of Experimental Biology, 1970ABSTRACT The dimensions of the semicircular canals of pike can be expressed as allometric functions of the body length L. The equal sensitivity of pike of different sizes to rotatory stimulation can be explained as a quadratic bending of the cupula.

Operative Techniques in Otolaryngology-Head and Neck Surgery, 2014
In the evaluation of patients with suspected superior (or posterior or lateral) semicircular canal dehiscence syndrome, imaging plays a crucial corroborative diagnostic role. The variable audiologic and vestibular signs and symptoms may be attributed to a third-window phenomenon, directly visible on computed tomography as a defect in the superior or ...

Multiple dehiscence of semicircular canals
The Journal of Laryngology & Otology, 2006Dehiscence of the semicircular canal is an uncommon condition and has been reported to involve the roof of the superior semicircular canal. We describe a case with dehiscence of four semicircular canals and in areas not involving the roof of the superior semicircular canal.

Prostaglandins in the semicircular canal of the frog
Hearing Research, 1987The synthesis of prostaglandins by ampulla and duct tissue isolated from the frog posterior semicircular canal was investigated in vitro. Ampulla and duct produced PGE2 (9 and 6 pg/structure, respectively) and prostacyclin (26 and 12 pg/structure). In the ampulla, prostaglandins mostly originated from the part containing dark and sensory cells and was ...

Fistula of the lateral semicircular canal
Clinical Otolaryngology, 1978The principles enunciated by Adam Politzer concerning the management of fistula of the lateral semicircular canal are as true today as they were during his time, in spite of the advances made in otologic surgery during the past 25 years or more. If a fistula of the lateral semicircular canal is suspected or proven, the patient's hearing has a greater ...

Cupulolithiasis of the horizontal semicircular canal
European Archives of Oto-Rhino-Laryngology, 2011To clarify whether positional nystagmus of horizontal cupulolithiasis contains vertical and torsional components, and to quantify the asymmetry, we analyzed nystagmus in four positions (healthy-ear-down, affected-ear-down, supine, nose-down), using 3-dimensional video-oculography.

Congenital Aplasia of the Semicircular Canals
Otology & Neurotology, 2003To describe the underrecognized inner ear malformation characterized by complete aplasia of the labyrinthine semicircular canals associated with a relatively well-formed cochlea, to investigate its relationship with known syndromic forms of hearing loss, and to hypothesize regarding the potential embryopathogenesis of this anomaly.A retrospective case ...

The crista of the semicircular canal is a receptor of rotatory movement, which enables its perception in any plane of rotation. Three semicircular canals, horizontal, anterior and posterior, open into the utricle.

Acoustic Stimulation of the Semicircular Canals
Otolaryngologic Clinics of North America, 1995Stimulation of the semicircular canals provides an alternative method of vibratory stimulation of the auditory system. The frequency response characteristics of stimulation of the tympanic membrane, malleus, stapes, round window, and fenestrated semicircular canal are presented in this article.
