The presence of a vocal ligament in fetuses: a histochemical and ultrastructural study.

Although it is currently believed that the vocal ligament of humans undergoes considerable development postnatally, there is no consensus as to the age at which it first emerges. In the newborn infant, the lamina propria has been described as containing a sparse collection of relatively unorganized fibres. In this study we obtained larynges from autopsy of human fetuses aged 7-9 months and used light and electron microscopy to study the collagenous and elastic system fibres in the lamina propria of the vocal fold.

Morphometric study on the anatomy of the fetal cricoid cartilage and comparison between its inner diameter and endotracheal tube sizes.

Objectives: The high incidence of respiratory disorders is one of the main problems in perinatal medical care. With the increased use of intubation, the incidence of laryngeal injury causing stenosis has also increased. The principal constriction point in the infant's larynx is the midcricoid area.

T-shaped microsuture: a new suture technique for laryngeal microsurgery.

Unlabelled: To describe a new suture technique for laryngeal microsurgery and to test its applicability in human cadaver larynges. The new technique was experimentally tested in freshly excised human larynges fixed to a larynx holder appropriate for the simulation of laryngeal microsurgery. A mucosal flap was created in the vocal fold for the fabrication of a pocket for subepithelial fat implantation, and the wound edges were then brought together and sutured using the proposed technique.

Structural brain abnormalities in early-onset schizophrenia.

Background: Few studies investigated brain abnormalities in early onset schizophrenia.

Objective: To assess computed tomography (CT) abnormalities in patients with childhood or adolescence onset schizophrenia.

Method: CT scans of patients with childhood (6 to 11 years old) (N=6) or adolescence (12-17 years old) (N=9) schizophrenia were compared to normal controls.
