Objective: Condylectomy was performed to treat condylar osteoma or hyperplasia. Introduced two methods of condylectomy via intraoral approach and evaluated their clinical results.
Methods: Thirty-five patients, aging from 22 to 57.21 years, were treated by condylectomy via intraoral approach, of which 21 were condyle osteoma, 14 hemimandibular hyperplasia and condylar hyperplasia. Intraoral vertical ramus osteotomy (IVRO) were used in 32 patients and intraoral condylectomy via coronoid process resection was used in 3 patients.
Results: The treatment results including oral function and facial symmetry after the operation were good in all patients. The temporomandibular joint (TMJ) dysfunction syndrome alleviated or disappeared. The follow-up period was 6 months to 3 years, and no relapse of condylar osteoma or hyperplasia was found. The patients who had IVRO and TMJ reconstruction had some degree of transplanted bone resorption, and one patients had relapse of facial deformity. But the patients who had intraoral condylectomy via coronoid process resection only had mild condyle remodeling and no obvious bone resorption was noted.
Conclusions: The two methods of intraoral condylectomy introduced in this stugy can successfully correct the facial deformity and TMJ dysfunction caused by condylar osteoma or hyperplasia. But the surgeons need to have excellent surgical skills and careful selection of the indications.

In this study we retrospectively reviewed our clinic's treatment of unilateral condylar hyperactivity (UCH). We used computer-guided proportional condylectomy, which was conducted both through preauricular and intraoral approaches, then analysed the advantages and disadvantages of the two techniques. A computer-guided treatment algorithm is also presented.

Article Synopsis
- An 18-year-old female patient with right condylar hyperplasia experienced significant facial asymmetry and an anterior open bite due to her condition and tongue-spitting habit.
- After considering treatment options, she underwent a right condylectomy followed by orthodontics, which included tooth extractions and the use of miniscrews to align her teeth and jaws.
- The outcome resulted in improved facial symmetry, closure of the open bite, and proper alignment of her dental structures, demonstrating the effectiveness of the combined surgical and orthodontic approach.
Mandibular deviation (MD) is a common reconstruction sequela after segmental mandibulectomy. Although proper postoperative rehabilitation is critical for MD management and minimization, the information available is limited. This report describes postoperative rehabilitation with an occlusal splint fabricated using computer-aided design (CAD) and computer-aided manufacturing (CAM) (CAD/CAM-OS) and the results of a threedimensional occlusal analysis using an intraoral scanner after hemimandibulectomy and plate reconstruction.

This study compares the accuracy and effectiveness of our novel 3D-printed titanium cutting guides with intraoperative surgical navigation for performing intraoral condylectomy in patients with mandibular condylar osteochondroma (OC). A total of 21 patients with mandibular condylar OC underwent intraoral condylectomy with either 3D-printed cutting guides (cutting guide group) or with surgical navigation (navigation group). The condylectomy accuracy in the cutting guide group and navigation group was determined by analyzing the three-dimensional (3D) discrepancies between the postoperative computed tomography (CT) images and the preoperative virtual surgical plan (VSP).
