A laryngocele is seen as a cyst filled with air or liquid in its normal location in the CT, and appears as a well-circumscribed air-filled enlargement that represents extension and elongation of the laryngeal appendices (saccules) of the laryngeal ventricle (2).
The unilateral dysfunction of the CSH or saccule was equally distributed between the implanted ear and without CI (14:9 and 22:18, respectively), and the differences in proportions were not statistically significant [23].
Laryngocele is an abnormal dilatation or herniation of the laryngeal saccule that extends upward within the false vocal fold in communication with the laryngeal lumen.
Endocytosis dependent pathway is an energy and temperature dependent transport process which involves engulfing of extracellular materials within a segment of the cell membrane to form a saccule or a vesicle (hence also called as corpuscular or vesicular transport) which is then pinched off intracellularly into the matrix/cytoplasm of the cell [101].
Utricle, saccule and cochlear duct in relation to stapedotomy: A histologic temporal bone study.
The utriculo-endolymphatic valve (UEV) opening is assumed to be located in the anteroinferior wall of the utricle, and the utricle is assumed to be separate from the saccule [19-23].
Diagnosis: This species is distinguished by the following combination of character states: body size 481-514 x 348-365; translamellar line present, interrupted medially; lamellar setae thickened; sensilli long, with asymmetrically dilated, barbed head; one pair of muscle sigilla present posterior to each saccule Sa, three pairs of muscle sigilla present posterior to each saccule ST.; prolamella present; coronal setae of ovipositor present; hypostomal setae a thicker than others, setae m very short; tarsi I with 18 setae.
Two sacs, called the utricle and saccule, make up the inner ear's vestibule and three fluid-filled loops, known as the semi-circular canals, detect the rotation and tilting movements of the head.
The vestibular organ is responsible for the balance and consists of the saccule, the utricle, and three semicircular canals (3).
* The vestibular system of each inner ear (semicircular canals, utricle and saccule) controls rotatory movements and orientation in, to and fro, up and down, and angular movements.
The "otolithic organs," as they are known, are a pair of sensors, the utricle and the saccule, nestled in the labyrinthine architecture of the inner ear....
A laryngocele is dilatation of the laryngeal saccule, a small pouch arising from the roof of the ventricle.14 Laryngoceles confined to the larynx are known as internal laryngoceles.
