Condylar Reabsorption after orthognathic surgery is a rare but well-known clinical entity that affects the temporomandibular joint (TMJ). The development of a protocol is recommended because there are few standardized treatments for the approach of this clinical consequence. The objective of this systemic review is to des- cribe the treatments associated with the management of condylar reabsorption after orthognathic surgery. A search was made in the Pubmed, Google Scholar, Science Direct and Crochane databases from1990 to 2022 using the following keywords: orthognathic surgery adding condylar resorption, progressive condylar resorption, idiopathic condylar resorption, condylar atrophy or condylysis. All articles were selected based on the inclusion and exclusion criteria preventatively established. The systematic review began with 15,182 articles, and after applying the inclusion and exclusion criteria this number was reduced to 21 articles. The total number of patients obtained was 3,285 with a predilection for the female gender in 47.5 % (n = 1,561) and 12.75 % (n = 419) for the male. The range of ages goes from 14 to 50 years, with a mean of 23.7 +/ - 6. The patients were diagnosed in 90.7 % (n = 2,979) with class II dentoskeletal deformity and 9.31 % (n = 306) with class III dentoskeletal deformity. 247 were diagnosed with condylar reabsorption after orthognathic surgery. Only three authors clearly des- cribe the treatments indicated in patients diagnosed with condylar resorption after orthognathic surgery; one being joint replacement and orthognathic surgery, another one referring to treating condylar reabsorption with orthognathic surgery retreatment and the last one used a costochondral graft. There are few standardized treatments for the management of condylar resorption in patients that underwent orthognathic surgery. The main problem of the research was represented by the existing diversity in the literature and in the way of reporting the treatments carried out.

Osteomas are benign, slow-growing, continuous benign bone tumors, consisting mainly of cortical or cancellous bone. Although they are relatively rare, they can manifest as single or multiple lesions, affecting various areas of the maxillofacial region. We present the case of a 26-year-old male patient diagnosed with class II dentofacial anomaly and obstructive sleep apnea syndrome (OSAS). During a scheduled orthognathic surgery to correct his malocclusion, the presence of an intrasinusal lesion in the right maxillary sinus was evidenced, which was completely extirpated and sent for histopathological study. The diagnosis of osteoma was confirmed by imaging studies and a postoperative biopsy. Osteomas are the most frequent benign pathology in the paranasal sinuses. They can be asymptomatic or cause symptoms such as nasal obstruction, pain and sinusitis. Treatment depends on the clinical manifestation of the lesion and varies from follow- up to surgical resection, with surgery being necessary when symptoms affect the function of adjacent structures. Early diagnosis and appropriate surgical intervention are essential to manage sinus osteomas. The combination of orthognathic surgery and osteoma removal in a single procedure, as presented in this case, optimizes treatment, improves recovery and reduces the risks of complications. This comprehensive approach underscores the importance of personalized clinical and surgical management in complex cases. KEY WORDS: Osteoma, maxillary sinus, orthognathic surgery.

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
