Relationship between cervical spine and skeletal class II in subjects with and without temporomandibular disorders

AIM. To assess changes of cranio-cervical structure and of hyoid bone position in skeletal Class II subjects with and without Temporomandibular disorders (TMD). MATERIAL AND METHODS. The cephalometric analysis of 59 subjects with skeletal Class II were evaluated and compared. The measurements considerated were: ANB as parameter of Class II and C0-C1 distance, C1-C2 distance, cranio-cervical angle and hyoid bone position for the cervical spine analysis. Patients were divided into two subgroups: patients with TMD (group A) and patients without TMD (group B).

Odontoid screw placement for Anderson type II odontoid fractures. how do duration from injury to surgery and clinical and radiological factors influence the union rate? A multicenter retrospective study

Anderson type II odontoid fractures are severe conditions, mostly affecting elderly people (≥ 70 years old). Surgery can be performed as a primary treatment or in cases of failed conservative management. This study aimed to investigate how duration from injury to surgery, as well as clinical, radiological, and surgical risk factors, may influence the union rate after anterior odontoid screw placement for Anderson type II odontoid fractures.
