Discovery of pathologies by orthodontists on lateral cephalograms

Abstract

Objective: To determine the frequency of significant pathologies on lateral cephalograms discovered by orthodontists during their careers. Materials and Methods: A five-statement survey was sent to the 417 active and affiliate members of the Edward H. Angle Society of Orthodontists. The survey asked orthodontists to identify any significant radiographic pathology that they had discovered on lateral cephalograms during their careers to date. The data were analyzed statistically. Results: Of the 417 surveys, 201 were returned for a 48% response rate. Ninety-nine respondents or 49.3% of the sample had discovered at least one significant pathology. Of the 1.3 million patients observed by the orthodontists in the sample, 268 patients (0.02%) with significant pathologies had been identified. Younger orthodontists had a statistically greater potential to discover pathologies than older orthodontists. The general types of pathologies discovered were musculoskeletal (38%), glandular (28%), and dental groups (12%). Conclusions: About 50% of orthodontists will likely discover a significant, potentially life-affecting pathology on a lateral cephalogram. (Angle Orthod. 2011;81:58-63.)

Morphometric analysis of the sella turcica in Turkish individuals with different dentofacial skeletal patterns

“…The normal dimensions of sella turcica range from 4 mm to 16 mm for length, depth, and diameter [4,8,14,16,28]. The discrepancies in those studies may be due to different landmarks representing the same dimensions, different degrees of magnification, or different compositions of the study groups (age, gender, ethnicity, etc.)…”

Sella turcica anomalies on lateral cephalometric radiographs of Polish children

“…28% of abnormalities discovered by orthodontists on lateral cephalograms are glandular anomalies, with pituitary adenoma visible as enlarged sella turcica being the most frequent. 5 In the embryological development of the sella turcica, neural crest cells and mesodermal cells are involved. Thus, shape anomalies of the sella turcica may both be Figure 1 Cephalometric landmarks used.…”

“…10 Bu hastalar var olan semptomların şiddetine göre ilaç tedavisi ile cerrahi tedavi ile ya da herhangi bir tedaviye gerek duyulmadan takip edilmektedir. Moffitt 41 , 29 yaşında ortodontik tedavi görmek için başvuran bir hastanın lateral sefalometrik filminin değerlendirilmesi sırasında sella tursikanın genişlemiş olduğunu fark etmiştir. Hasta endokrinoloji kliniğine yönlendirilmiş ve hastaya tiroid hormonu salgılayan hipofizeal makroadenoma tanısı konmuştur.…”
