The triangle is formed by joining the cephalometric points retrognathion (the most inferior, posterior point on the mandibular symphysis), hyoidale (the most superior, anterior point on the body of the hyoid bone
) and C3 (the most anteroinferior point on the third cervical vertebra).
The flap was elevated up to the hyoid bone on the fascia of the thyroid gland and the laryngeal perichondrium, infrahyoid muscles were cut from the body of the hyoid bone
and dissection was advanced laterally to expose the pedicle.
Our results were different from the other studies in the literature, because we did not measure the distance of CB to the greater horn of the hyoid bone, but to the midline of the body of the hyoid bone. We accepted this point as the reference point because the body of the hyoid bone may be more clearly identified on physical examination of neck, and structural alterations of the greater horn of hyoid bone on the right and left sides might cause different measurements.
(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.
CT of the neck demonstrated enlargement of the body of the hyoid bone
with massive osteolysis and cortical destruction (Figure 2a, 2c).
Usually the Thyroglossal duct cyst is removed by Sistrunk's procedure, wherein excision of the Thyroglossal duct cyst, the central portion of the body of the hyoid bone
, and a core of tissue around the Thyroglossal tract to open into the oral cavity at the foramen cecum.
(11) In males the greater and lesser cornua fuse to the body of the hyoid bone
unilaterally at 38.25 and bilaterally at 53.16 years of age respectively while females achieve boney fusion unilaterally and bilaterally at 38.00 and 48.50 years of age respectively.
The arch itself gives rise to the handle of the malleus, the long process of the incus, and the stapes superstructure, as well as the styloid process, stylohyoid ligament, lesser cornu, and upper body of the hyoid bone
About 92% of LGT were found attached to the body of the hyoid bone
These are joined together by an intermediate tendon that passes through a fibrous sling that is attached to the body of the hyoid bone
(Lockhart et al., 1983).
The cyst and the duct were excised along with the body of the hyoid bone
(figure 3, B).
