Diagnostic Techniques Used in Facial Asymmetry Associated with Osteochondroma and Unilateral Condylar Hyperplasia

Increased volume of the mandibular condyle is frequently associated with diseases such as condylar hyperplasia (CH) and condylar osteochondroma (OC). HC is defined as an excessive growth of the condyle, non-neoplastic, self-limited and generally unilateral, first described by Humphrey in 1856. OC is an exophytic lesion covered by cartilage, being one of the most common benign tumors of the skeleton, considering that less than 1 % occurs in the maxillomandibular region. with the objective of knowing what is the most used diagnostic method in patients with facial asymmetry associated with condylar hyperplasia and mandibular osteochondroma? The last 10 years. After applying the inclusion and exclusion criteria, a total of 100 articles were obtained. The selected articles comprised a total sample of 1559 patients, 971 women (62.2 %) and 588 men (37.8 %), the ages of the patients ranged from 6 to 83 years. The complementary examinations used for diagnosis were diverse and not exclusive to each article, including panoramic radiography and teleradiography (90 %), computed tomography (CT) (57 %), cone beam computed tomography (CBCT) (35 %), Single-photon emission computed tomography (SPECT) (44 %) and magnetic resonance imaging (7 %). In addition, diagnostic confirmation was performed through histopathological studies in (36 %) of the articles after treatment. This concludes the importance of the com- plete imaging examination in the diagnosis of this type of pathology, without leaving aside histopathological confirmation to evaluate the response to treatment
