The muscle parts attaching to the thyroid cartilage
were incised to expose the lamina of the cartilage and TF clearly.
It lies directly below the thyroid cartilage
and it represents the anatomic lower limit of the larynx.
An injection needle (1.1 x 40 mm, 21# Sterican Hypodermic Needle; Braun Melsungen AG, Melsungen, Germany) is used to mark a point [C in [Figure 1] on the thyroid lamina 2 mm at least anterior to the reference point [B in [Figure 1] and 5 mm superior to the inferior margin of the thyroid cartilage
in men and 4 mm in women.
Strauss, "Stable 3d mass-spring models for the segmentation of the thyroid cartilage
," in Proceedings of the DAGM, Otto-von-Guericke-Universitat Magdeburg, Vienna, Austria, August 2005.
Then, we proceeded to the external approach, and thyroid cartilage
window with a Skeeter drill window of 12 mm  was made and the foreign body was retrieved (Figures 2 and 3).
(2006) performed a study on 36 cadavers, and found that the CCA bifurcated at the level of the body of the hyoid bone in 15 (88.9%), at the superior border of thyroid cartilage
in 11 (42.3%), and at the tip of the greater horn of hyoid bone in 8 (15%) cadavers.
During thyroid surgery two possible sites of tracheal injury exist: at the isthmus, when the thyroid is separated from the trachea, and at the area where the recurrent laryngeal nerve enters the thyroid cartilage
during lateral and posterior dissection .
After the sternocleidomastoid muscle and the strap muscle were identified, we cut through the linea alba cervicalis incision with a harmonic scalpel between the strap muscles from the suprasternal notch to thyroid cartilage
. The general principle of surgical procedures for robotic total thyroidectomy was the same as conventional open thyroidectomy.
A post mortem examination by a Home Office pathologist concluded the victim died from injuries consistent with a ligature compression of the neck, including fractures of the thyroid cartilage
Particular findings include horizontal thyroid cartilage
fractures (Figure 1), fractures of the superior thyroid cornua as well as hyoid fractures (Figure 2), malalignment and malposition injuries.
Eventually, each recurrent laryngeal nerve enters the larynx between the inferior cornu of the thyroid cartilage
and the arch of the cricoid, branching after laryngeal penetration in two-thirds of cases.
