The stylohyoid ligament extends from the styloid process of the temporal bone to the lesser horn of the styloid bone. Various forms of ossification of this anatomical structure have been described in the literature. In our case, there was bilateral ossification of the stylohyoid ligament, a very rare occurrence. Ossification was partial on the righ...

... The stylohyoid complex is composed of several structures such as the styloid process of the temporal bone, the lesser horn of the hyoid bone, and the stylohyoid ligament between these structures (Anti c et al., 2016). Stylohyoid ligament is a fibrous remnant of the Reichert's cartilage of the second pharyngeal arch. ...
... Based on radiographic data, the prevalence of an elongated styloid process in different populations ranges from 4 to 84.4% (Gokce et al., 2008;Ekici et al., 2013;Zokaris et al., 2019). Among those, it is thought that only a small percentage (from 4% to 10.3%) has symptoms suggestive of the anomaly (Anti c et al., 2016). ...
This article reports two patients with stylohyoid complex syndrome.
Cone beam computed tomography examination of the 37-year-old Caucasian woman with hemifacial pain, radiating to the left ear which intensified in response to opening the mouth revealed the ossified distal part of the left stylohyoid ligament, 23.85 mm long, which had a contact with the lesser horn of the hyoid.
A 43-year-old man with a 5-month history of pain in the anterolateral surface of the neck and temporomandibular joint on the right side when swallowing and yawning had the styloid process elongation with a “bayonet-like” deformity on the same side.
Ossification of the stylohyoid ligament, elongation and bending of the slyloid process, as a reason of the lateral neck and/or facial pain is not commonly suspected in clinical practice where diagnosis is often first made radiologically.
