Davis WL, Smoker WR, Hamsberger HR The normal and diseased infrahyoid
retropharyngeal, danger, and prevertebral spaces.
group: Approximately 2 cm lateral to the thyroid cartilage on the left side of the neck.
Apart from the description of only thirty-two cases of double ectopic thyroid, no case of an ectopic lingual thyroid combined with infrahyoid
region ectopic gland has been reported in literature.
Specific areas addressed include, cerebral hemispheres, the sella/suprasellar region, the pineal region, orbit, nose, and sinuses, the suprahyoid and infrahyoid
neck, and extradural space, among many others.
The location of the thyroglossal duct cysts was infrahyoid
position in 11 (44%) followed by suprahyoid position in 9 (36%) as shown in table 2.
Ultrasound anatomy of the neck: The infrahyoid
It is commonly associated with the poor development of the articular fossa, laxity of the temporomandibular ligament or joint capsule, and excessive activity of the lateral pterygoid and infrahyoid
muscles due to drug use or disease.
With the animal in the supine position after a vertical midline cervicotomy, the infrahyoid
muscles were separated from the tracheal axis.
Proposal for staging of lymphatic malformations of the head and neck (adapted from de Serres ) Stage Location of lesion I Unilateral infrahyoid

and suprahyoid IV Bilateral suprahyoid V Bilateral infrahyoid
There are another three suprahyoid muscles: the geniohyoid, stylohyoid and mylohyoid, which are also inserted in the hyoid bone and, together with the digastric muscle, anchor this bone against the traction of the infrahyoid
muscles (Lockhart et al.
muscles, represented by esternohyoideous, pull the hyoid bone inferiorly and subsequently providing their return to resting position characterizing the end of swallowing [31,32].
