[PMID: 34873102 DOI: 10.1097/scs.0000000000008394] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2021] [Accepted: 11/08/2021] [Indexed: 02/05/2023] Open
Abstract
PURPOSE To investigate current Computer-Aided Design and Computer-Aided Manufacturing (CAD/CAM) technologies applied in the treatment of dentofacial deformities secondary to condylar osteochondroma and introduce a modified method with additional pre-bent titanium miniplates to improve the accuracy of operation. METHODS Literature review about the application of CAD/CAM in the treatment of condylar osteochondroma and secondary dentofacial deformities was conducted. And 8 patients with condylar osteochondroma and secondary dentofacial deformities were treated by the CAD/CAM cutting and drilling surgical guides as well as pre-bent titanium miniplates. Pre- and post-operative 3D-cephalometric measurement were recorded and the difference between virtual simulation and postoperative modeling images was measured. Follow-up and radiographic examinations were performed. RESULTS A total of 17 studies (including 216 patients) about the application of CAD/CAM in the treatment of dentofacial deformities secondary to condylar osteochondroma have been reported since 2010, including the 8 present patients. In our study, all patients were satisfied with the surgical outcome, without obvious relapse or evidence of temporomandibular joint disorder or other complications during follow-up; all patients avoided condylar reconstruction and sagittal split of ramus osteotomy on the ipsilateral mandible side. Comparison between simulated plans and actual postoperative outcomes showed surgical simulation plan was accurately transferred to the actual surgery. CONCLUSIONS The application of CAD/CAM cutting and drilling guides as well as pre-bent titanium plates could achieve more accurate and favorable outcomes, improving the clinical planning and surgical execution for patients with condylar osteochondroma and secondary dentofacial deformities.

[PMID: 33994297 DOI: 10.1016/j.jcms.2021.04.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 03/15/2021] [Accepted: 04/11/2021] [Indexed: 10/21/2022] Open
Abstract
The aim of this study was to evaluate and discuss the long-term outcomes of patients with condylar osteochondroma managed through 3 different surgical techniques. Seven patients with condylar osteochondroma treated in the author's department from May 2012 to January 2019 were included in this retrospective study. Clinical evaluations (visual analogue scale for TMJ pain, jaw function, symmetry, and quality of life), maximum interincisal opening (MIO) and radiological findings were collected pre- and postoperatively. Other parameters assessed included tumour size and location; complications and follow-up. Radical condylectomy with immediate total joint alloplastic reconstruction was performed in 4 patients, local excision in 2 patients and low condylectomy with concomitant orthognathic surgery in 1 patient. During an average follow-up period of 40,8 months no clinical or radiographic signs of recurrence were found. Average MIO increased from 25,5mm to 39,5mm at the longest follow up, and all clinical evaluations were greatly improved. In conclusion, the described surgical techniques appear valuable in the treatment of condylar osteochondroma. Local excision is indicated in tumor involving less than half the surface of the condylar head; radical condylectomy with immediate alloplastic total joint reconstruction is indicated in gigantic lesion compromising the anatomical components and function of the joint. Orthognathic surgery procedures should be combined with tumor resection when correction of associated dentofacial deformities is indicated.

Abstract
Maxillofacial osteochondromas are considered benign neoplasms, and compared with their extracranial variant are relatively rare. When they involve the mandibular condyle they can induce significant facial deformity, malocclusion and various temporomandibular joint symptoms. Complete excision is considered the standard of care, but can lead to a reduction in the height of the ipsilateral mandible with resultant complications. In such cases, reconstruction is usually warranted and may be approached in various ways. This case report demonstrates a straightforward, accurate and reproducible approach to reconstructing the TMJ, facial profile and occlusion following resection of a large TMJ osteochondroma, without the need for concomitant orthodontics.

Abstract
Background Mandibular condylar osteochondroma (OC) could lead to facial morphologic and functional disturbances, such as facial asymmetry, malocclusion, and temporomandibular joint dysfunction. However, after condylar OC resection, the inaccurate reposition of the neocondyle still needs to be solved. The purpose of this study was to explore the feasibility of the condylar osteotomy and repositioning guide to reposition the neocondyle in the treatment of patients with severe deformity secondary to condylar OC. Results Three patients with severe deformity secondary to OC of the mandibular condyle were enrolled in this study. With the aid of condylar osteotomy and repositioning guide, condylar OC resection and repositioning were carried out, and the accuracy and stability of these guides were evaluated. All patients healed uneventfully, and no facial nerve injury and condylar ankylosis occurred. Compared with the computerized tomography scans in centric relation before surgery and 3 days after surgery, the results showed that the facial symmetry was greatly improved in all the patients. Also, after the superimposition of the condylar segments before surgery and 3 days after surgery, the postoperative reconstructed condyles had a high degree of similarity to the reconstruction of the virtual surgical planning. Observed from the sagittal and coronal directions, the measurements of condylar positions were very close to those of virtual surgical planning. Moreover, it also showed stable results after a 1-year follow-up. Conclusions For patients with severe deformity secondary to condylar OC, condylar osteotomy, and repositioning guide was expected to provide a new option for the improvement of facial symmetry and occlusal relationship.

Abstract
Osteochondroma is a common benign tumor of bones, but it is rare in the mandibular condyle. With its outgrowth it manifests clinically as deviation of the mandible limitation of mouth opening, and facial asymmetry. After the tumor is diagnosed on the basis of clinical symptoms and radiographic examination including cone-beam computed tomography (CBCT) analysis, an appropriate surgery and treatment plan should be formulated. Herein, we present the case of a 44-year-old female patient who visited our dental hospital because her chin point had been deviating to the left side slowly but progressively over the last 3 years and she had difficulty masticating. Based on CBCT, she was diagnosed with skeletal Class III malocclusion accompanied by osteochondroma of the right mandibular condyle. Maxillary occlusal cant with the right side down was observed, but it was confirmed to be an extrusion of the molars associated with dental compensation. Therefore, after intrusion of the right molars with the use of temporary anchorage devices, sagittal split ramus osteotomy was used to remove the tumor and perform orthognathic surgery simultaneously. During 6 months after the surgery, continuous bone resorption and remodeling were observed in the condyle of the affected side, which led to a change in occlusion. During the postoperative orthodontic treatment, intrusive force and buccal torque were applied to the molars on the affected side, and a proper buccal overjet was created. After 18 months, CBCT revealed that the rate of bone absorption was continuously reduced, bone corticalization appeared, and good occlusion and a satisfying facial profile were achieved.

Abstract
PURPOSE We evaluated the stability of orthognathic surgery in the treatment of unilateral condylar osteochondroma combined with jaw deformity. PATIENTS AND METHODS Patients with unilateral condylar osteochondroma and jaw deviation deformity who had undergone surgery at the Ninth People's Hospital of Shanghai Jiaotong University School of Medicine from July 2014 to March 2017 were enrolled. The operation included a low condylectomy and both Le Fort I osteotomy and bilateral mandibular sagittal split osteotomies. ProPlan CMF, version 1.4, software (Materialise, Leuven, Belgium) was used to reconstruct and measure the preoperative, immediately postoperative, and follow-up (>6 months) maxillofacial computed tomography images. The position of the jaw and contralateral condyle and remodeling of the affected side were compared during follow-up. RESULTS Eight patients were included in the present study. The canting of the maxilla was significantly decreased postoperatively, and the contralateral condyle had rotated inward. The position of the maxillary and contralateral condyles was stable during follow-up, and the posterior aspect of the affected condyle demonstrated significant resorption. CONCLUSIONS The results of single-stage surgery combined with orthognathic surgery and condylar osteochondroma resection were stable, and the affected condyle stump had adaptively reconstructed.

Abstract
Osteochondroma manifests as a benign tumor that occurs as an abnormal bony development. This tumor is commonly asymptomatic and presents an exophytic outgrowth on bone surfaces, near synovial joints, a condition that invariably induces evident facial deformities. Treatment for this type of tumor usually involves a surgical approach promoting a total or partial resection of the affected anatomical area associated to prosthetic reconstruction of the bone area extracted. We present a case report about a giant mandibular condyle osteochondroma in a 37-year-old female patient. Her treatment involved a total condylectomy without immediate condylar reconstruction, which would be performed in a posterior surgical approach. During the patient's follow-up (every 6 months of post operation), a spontaneous and rudimentary condyle-like formation was observed. Because the stomatognathic function and facial harmony were satisfactory, we observed the condyle-like development for 5 years of follow-up. Also, because both the aesthetic aspect and functional evolution of the maxillary bone were considered satisfactory, no complementary reconstruction surgical treatment was required for the giant osteochondroma of the mandibular condyle.

Abstract
Background Both mandibular condylar hyperplasia and condylar osteochondroma can lead to maxillofacial skeletal asymmetry and malocclusion, although they exhibit different biological behavior. This study attempted to compare the histological features of mandibular condylar hyperplasia and condylar osteochondroma using hematoxylin-and-eosin (H&E) staining, and immunohistochemistry staining of PCNA and EXT1 with quantitative analysis method. Results The H&E staining showed that condylar hyperplasia and condylar osteochondroma could be divided into four histological types and exhibited features of different endochondral ossification stages. There was evidence of a thicker cartilage cap in condylar osteochondroma as compared condylar hyperplasia (P = 0.018). The percentage of bone formation in condylar osteochondroma was larger than was found in condylar hyperplasia (P = 0.04). Immunohistochemical staining showed that PCNA was mainly located in the undifferentiated mesenchymal layer and the hypertrophic cartilage layer, and there were more PCNA positive cells in the condylar osteochondroma (P = 0.007). EXT1 was mainly expressed in the cartilage layer, and there was also a higher positive rate of EXT1 in condylar osteochondroma (P = 0.0366). The thicker cartilage cap, higher bone formation rate and higher PCNA positive rate indicated a higher rate of proliferative activity in condylar osteochondroma. The more significant positive rate of EXT1 in condylar osteochondroma implied differential biological characteristic as compared to condylar hyperplasia. Conclusions These features might be useful in histopathologically distinguishing condylar hyperplasia and osteochondroma.

Abstract
We have introduced an effective treatment for mandibular condylar osteochondroma with a digital cutting guide and endoscopically-assisted vertical ramus osteotomy (VRO). Eleven patients with unilateral condylar osteochondroma, who did not require orthognathic surgery or had less than 3mm deviation of the chin and a stable occlusion, were treated during the period April 2013-January 2017 with a digital cutting guide and endoscopically-assisted VRO. Clinical data collected included the occlusion, facial contour, and maximum mouth opening (MMO). Computed tomographic (CT) scans were taken before and after operation. Two patients also had additional shaping of the mandibular contour. The pathological diagnosis was confirmed to be osteochondroma in all cases. A mean (range) 19 (12-40) months of follow-up for all 11 cases showed stable postoperative occlusion and facial aesthetics. There were no functional disturbances, recurrence, or condylar absorption. VRO is an alternative to orthognathic surgery for patients with osteochondroma who do not have severe malocclusions. The digital cutting guide and endoscopically-assisted VRO make it possible to achieve precise resection of the tumour and maintain the occlusion with minimal invasion.

Abstract
An osteochondroma, when reported in the maxillofacial region, is a benign neoplasm that involves the skull base, maxillary sinus, zygomatic arch, or mandible. Most commonly, the osteochondroma occurs in the coronoid process and the condyle. One rare subtype of osteochondroma reported in the literature, termed Jacob disease, arises from the coronoid process and interferes with the zygomatic arch. This report describes a unique case of an isolated osteochondroma arising from the zygomatic arch and interfering with the coronoid process, which was treated through surgical excision by an intraoral approach. The literature search indicated that this is 1 among only 9 other reported cases since 1964 in which an osteochondroma arose primarily from the zygomatic arch.

Abstract
This original case report describes the morphologic changes caused by a mandibular condylar osteochondroma (OC) on a female patient and its treatment. The changes were identified by comparing her final records from a previous orthodontic treatment, without the presence of OC, to records taken before a second treatment, with a developed OC. The diagnostics and treatment for the OC and its consequences were described and discussed in this paper. Treatment included orthodontics with a lingual appliance, low condylectomy on the affected side, high condylectomy on the contralateral side, bilateral disc repositioning and orthognathic surgery. It was concluded that the OC caused a Class III subdivision malocclusion, midline deviation and an edge-to-edge bite on the left side, a cant of the occlusal plane on the Z-axis and a deviation of the pogonion to the left. Treatment was successful and stable long term (36 months) with good occlusal, aesthetical and functional results.

Abstract
OBJECTIVE Surgical treatment of condylar osteochondroma combined with secondary dentofacial deformities is a significant clinical challenge. The authors present this review article to provide some guidelines for the surgical treatment for this severely complex condition. MATERIALS AND METHODS Diagnosis and treatment protocol of condylar osteochondroma patients combined with secondary dentofacial deformities are discussed at the basis of published literatures and the authors' own clinical experiences. Proper treatment protocol was designed according to features of tumor and dentofacial deformities. Follow-up and radiographic examination was performed to evaluate recurrence of tumor, occlusion, joint function, and facial appearance after surgery. RESULTS The patients received 1 or several methods of resection of tumor, condylar reconstruction, correction of skeletal deformities, and treatment of malocclusion. The condylar ostechondroma and secondary dentofacial deformities were treated satisfactorily. Temporomandibular joint function, occlusion, and facial appearance were improved obviously after operation evidenced by radiographic examination and follow-up. CONCLUSION Surgical management of condylar osteochondroma with secondary dentofacial deformities requires careful patient selection, treatment planning, and precise execution. This article has reviewed the current status of surgical treatment options and provided practical guidelines for oral and maxillofacial surgeons to consider their clinical practice.

Abstract
A 21-year-old woman presented with facial asymmetry. Crepitus and clicking of the temporomandibular joint were noted. The midline deviated 5.5 mm to the left, and secondary malocclusion was observed. Panoramic and cone-beam computed tomographic images showed an irregular and exophytic bony mass on the anteromedial surface of the right mandibular condyle. A 3-phase bone scan revealed increased tracer uptake on the affected side. The lesion was treated with excision and reshaping under the diagnosis of osteochondroma confirmed by a histopathological examination. The lesion recurred after 3 years, and the patient underwent condylectomy. Mandibular condylar osteochondroma is often resected because it causes functional and aesthetic problems, but it rarely recurs. To the best of our knowledge, only 2 cases of recurrent osteochondromas of the mandibular condyle have been reported previously. Surgical treatment of the osteochondroma should be performed considering the possibility of recurrence, and long-term follow-up is recommended.

Abstract
Osteochondroma (OC) is a common slow growing tumour of bone. This lesion is frequently seen in the axial skeleton and is relatively uncommon in oral and maxillofacial region. In facial bones, it usually affects the mandibular condyle followed by coronoid process. Very few cases of condylar osteocondroma have been reported in the literature. The aim of this article was to present an atypical case of osteochondroma of bilateral mandibular condyle in an asymptomatic patient and facilitate making an exact diagnosis of it. To the best of our knowledge this is the 2(nd) case of this type reported in literature.

Abstract
Introduction: Osteochondroma (OC) is the most common benign tumor of the skeleton. However, patellar OC is very rare. Only five case reports have been published yet and only 1 after the year 1972. OCs grow during childhood through adolescence, but usually growing ends when the epiphyseal plates close. In an adult, the growth of an OC suggests the diagnosis of malignant transformation to a chondrosarcoma. However, enlargement of a patellar OC reported as benign after skeletal maturity is present in literature. Case Report: We report the clinical and radiologic findings of a patellar OC in a 50-year-old female, with a 3-year progression of swelling, not painful, well-defined margins, normal skin, and no neurovascular deficits or functional impairment. The tumor was surgically resected, and histopathological examination did not show malignancy. After 2 years of follow-up, the patient has no complaints and no signs of recurrence. Conclusion: Patellar OCsare extremely rare with only a few reports published. It should be kept in mind that benign OCs can show symptomatic growth in skeletally mature patients without malignant transformation.

Abstract
A significant proportion of facial asymmetry cases are caused by abnormal growth of the mandibular condyles. Surgical management is generally based on a condylectomy performed through a pre-auricular transcutaneous access. However, this approach entails potential neurovascular, salivary, and aesthetic complications. In this study, a proof-of-concept evaluation was performed of a novel minimally invasive technique for condylectomy performed through an intraoral approach. Based on precise three-dimensional virtual planning to define intraoperative references, this technique provides an excellent access for total or partial condylectomy through a limited intraoral incision. Piezoelectric surgery with customized attachments enables the safe, accurate execution of the condylectomy. In addition, experience gained in seven consecutive cases suggests that the need for coronoidectomy can be obviated, surgical time is reduced to an average of 16.9min, and postoperative morbidity is minimal. This alternative intraoral approach could become the treatment of choice for most condylar hyperplastic conditions.

Abstract
We describe our experience with conservative condylectomy for the correction of facial asymmetry in five patients with osteochondroma of the mandibular condyle. All five patients presented with malocclusion and facial asymmetry, which are common clinical findings of osteochondroma involving the mandibular condyle. We performed conservative condylectomy without additional orthognathic surgery for all five patients, preserving the vertical height of the condylar process as much as possible. Following surgery, intermaxillary traction using a skeletal anchorage system with rubber elastics was performed on all patients to improve occlusion, and, when necessary, additional minimal orthodontic treatment was performed. The mean follow-up period was 42 months. At the last follow-up visit, all patients exhibited satisfactory facial symmetry and remodeling of the remaining condyle, with stable health and no signs of recurrence. In conclusion, conservative condylectomy alone, without subsequent orthognathic surgery, is adequate for the restoration of facial symmetry and the preservation of vertical condylar height in select patients with condylar osteochondroma.

Abstract
OBJECTIVE The objectives of this study were to introduce the classification of osteochondroma of the mandibular condyle based on computed tomographic images and to present our treatment experiences. MATERIALS AND METHODS From January 2002 and December 2012, a total of 61 patients with condylar osteochondroma were treated in our division. Both clinical and radiologic aspects were reviewed. The average follow-up period was 24.3 months with a range of 6 to 120 months. RESULTS Two types of condylar osteochondroma were presented: type 1 (protruding expansion) in 50 patients (82.0%) and type 2 (globular expansion) in 11 patients (18.0%). Type 1 condylar osteochondroma presented 5 forms: anterior/anteromedial (58%), posterior/posteromedial (6%), medial (16%), lateral (6%), and gigantic (14%). Local resection was performed on patients with type 1 condylar osteochondroma. Subtotal condylectomy/total condylectomy using costochondral graft reconstruction with/without orthognathic surgeries was performed on patients with type 2 condylar osteochondroma. During the follow-up period, tumor reformation, condyle absorption, and new deformity were not detected. The patients almost reattained facial symmetry. CONCLUSIONS Preoperative classification based on computed tomographic images will help surgeons to choose the suitable surgical procedure to treat the condylar osteochondroma.

Abstract
Osteochondroma (OC) is one of the most common benign condylar tumours having both chondroma and osteoma. However, this tumour is most frequently found on the metaphyses of long bones and is unusual on the skull. When it affects the mandibular condyle, the cause could be due to trauma to the tempero mandibular joint (TMJ). Here, in this report we present a rare case of osteochondroma of left condyle region in a 36-year-old man. The patient had noticed pain in the left TMJ for six months. The lesion is surgically removed and histologically evaluated which composed of chondrocytes dispersed in hyaline matrix along with a rim of calcified bone at one end.

Abstract
Osteochondroma is a rare tumor of the mandibular condyle. Much confusion seems to exist in the literature in differentiating these tumors from chondromas as well as condylar hyperplasias. Due to considerable overlapping features between chondromas and condylar hyperplasia, it is likely to get misdiagnosed, thereby resulting in inadvertent errors in the treatment. A case report of a 35 year old male patient with mandibular deviation and malocclusion is presented here. He initially went unnoticed for features of an osteochondroma of the mandibular condyle but was subsequently treated for the same.

Abstract
Osteochondroma is frequently found in the general skeleton but is rare in the condylar region of the mandible. We report a case of an osteochondroma of large size and rapid growth in the mandibular condyle, which was treated with total condylectomy and condylar replacement with a costochondral graft and preservation of the articular disc. In cases with a healthy and well-positioned articular disc, it may be preserved with no need of disc repositioning.

Abstract
A 40-year-old Indian male patient was referred to the Department of Oral and Maxillofacial Surgery with a slowly enlarging intra-oral, right-sided palatal swelling of one-year duration, with a previous diagnosis of osteochondroma. Extraorally, patient presented with a mild right-sided facial swelling. On intraoral examination, the palatal swelling was extending from the distal aspect of canine to the distal aspect of second molar with involvement of the maxillary tuberosity. The swelling was non-tender, bony-hard in consistency and covered by normal mucosa. The medical history was non-contributory with no relevant family history of any skeletal disease. Despite the attempt for complete removal of the tumor previously, it recurred within six months. The present article reports an extremely rare clinical case of endosteal (central) osteochondroma, manifesting itself as a radiopaque mass in the right posterior aspect of the palate.

Abstract
Osteochondroma is one of the most common benign tumors of the skeleton. This tumor is rare in the craniofacial region, with the most common sites of occurrence being the coronoid process of the mandible and the mandibular condyle. Traditionally, the treatments of these lesions include total condylectomy or local resection of the lesion. Conservative condylectomy procedure with reshaping of the remaining condylar neck and repositioning of the articular disk has been suggested. This article aimed to describe a 35-year-old woman with osteochondroma in the left mandibular condyle who was treated by conservative condylectomy. The patient has been free of recurrence for 2 years, showing good aesthetic and functional stability.

Abstract
PURPOSE This study summarizes the literature concerning osteochondroma of the mandibular coronoid process and presents a case of 1-stage treatment for this condition and concomitant facial asymmetry. MATERIALS AND METHODS A 20-year-old man presented with osteochondroma of the mandibular coronoid process. Radiologic images showed a mushroom-shaped coronoid growth inside the zygomatic arch with outward expansion. Coronoidectomy and reduction malarplasty were performed in 1 stage. The literature on osteochondroma of the mandibular coronoid process since 1943 was reviewed concerning etiology, pathogenesis, clinical characteristics, diagnosis, and treatment. RESULTS At 20-month follow-up, the patient achieved markedly improved joint function and a symmetric facial appearance after excision of the osteochondroma. CONCLUSION Coronoidectomy combined with simultaneous reduction malarplasty could be an alternative and promising method to treat osteochondroma of the coronoid process with secondary facial asymmetry.

Abstract
BACKGROUND Osteochondromas (OCs) are rare in the craneofacial area (0.6%). We present 2 cases of OC of the mandibular condyle, emphasizing the surgical decision of each case. CASE 1: In a 48-year-old woman with facial asymmetry, left cross-bite, and mandible deviation to the left, a computerized tomographic (CT) scan confirmed the presence of a bony expansion of the right condyle. The clinical diagnosis was osteochondroma. The patient underwent condylectomy with costochondral reconstruction. CASE 2: In a 76-year-old woman with a 1-month history of right preauricular pain, CT showed a deformed right condyle with a bony mass at the base of the temporal bone and the articular fossa. OC of the skull base was diagnosed, with possibly a concurrent lesion of the condyle. The patient underwent condylectomy with the removal of the skull base mass and an inmediate TMJ reconstruction by means of an appropriately sized stock total TMJ prosthesis. CONCLUSIONS It is necessary to personalize the temporomandibular joint reconstructive options.

Abstract
BACKGROUND Osteochondroma is a common bone tumor and rarely affects the central nervous system. Although intraspinal osteochondromas are known to cause neurological deficits, intracranial osteochondromas with neurological compromise are very rare. CASE DESCRIPTION The authors report an exceptional case of a quadriparetic 73-year-old patient with a basioccipital bone osteochondroma growing into the foramen magnum. The embryology, differential diagnoses, and optimal management strategies are discussed. CONCLUSION Although extremely rare, osteochondromas should be included in the differential diagnoses of tumors within the foramen magnum. For the tumors originating from the basioccipital bone, a simple medial suboccipital approach might suffice, while for ventral tumors, a far lateral transcondylar approach is necessary to avoid any neurovascular complications. Despite potentially catastrophic presenting symptoms, these tumors are pathologically benign and complete excision often results in long-term cure. To the best of our knowledge, this is the first report of an osteochondroma arising from the basiocciput.

Abstract
Osteochondroma of the mandibular condyle has been found in the oral and maxillofacial region rarely. This paper describes a case of osteochondroma of the mandibular condyle in a 20-year-old woman, who was referred to our service with facial asymmetry, prognathic deviation of chin, cross-bite to the contralateral side, changes in condylar morphology, limited mouth opening, and malocclusion. Computed tomography (CT) was performed for better evaluation to the pathological conditions on the temporomandibular joint. Based on the clinical examination, patient history, and complementary exams, the hypothesis of osteochondroma was established. Condylectomy was performed using a preauricular approach with total removal of the lesion. After 3 years of postoperative follow up and orthodontic therapy, the patient is symptom-free, and has normal mouth opening with no deviation in the opening pattern.

Abstract
BACKGROUND Osteochondromas are one of the most common benign tumours of bone, but they are rare in the craniofacial region. These condylar tumours have been variably treated, including resection through local excision or condylectomy with or without reconstruction. METHODS A case of osteochondroma of the mandibular condyle and cranial base arising concurrently in the 76 years old patient was presented. The surgical excision of the skull base lesion and condylectomy with immediate reconstruction of temporomandibular joint was applied. RESULTS Based on the history, clinical examination and radiographic findings, osteochondroma of the skull base was diagnosed, with a concurrent lesion of the condylar process. Treatment methods for this patient included excision of the skull base tumour and condylectomy with immediate temporomandibular joint reconstruction using appropriately sized stock total temporomandibular joint prosthesis. At the 24 month follow-up, patient was free of pain and her maximal incisal opening was maintained, with no radiographic evidence of tumour recurrence or failure of the device. CONCLUSIONS Temporomandibular joint stock total replacement prosthesis became a good option to reconstruct both the fossa and the condyle in a one-stage surgery, due to the fact that both the condylar/mandibular and the fossa implants were stable in situ from the moment of fixation, with a good outcome at 24 month follow-up, with no loosening of the screws nor failure of the device.

Abstract
OBJECTIVES Osteochondromas are frequently found in the general skeleton, but are rare in the mandibular condyle. Radiographically, most reports describe osteochondromas as a mushroom-shaped bony enlargement capped with cartilage on the condylar surface. However, the radiographic appearance of this lesion on the panoramic radiograph has rarely been studied. The purpose of this article is to increase the radiographic knowledge of mandibular condylar osteochondroma and facilitate making an exact diagnosis through observing the lesional appearance on panoramic radiograph. METHODS The panoramic radiographs of 12 cases of mandibular condylar osteochondromas were reviewed. All cases were obtained from the Department of Oral Radiology, West China College of Stomatology, Sichuan University, between 1988 and 2006. The final diagnoses of all cases were based on pathology. RESULTS Osteochondromas may arise on different areas around the mandibular condyle and present diverse appearances on panoramic radiograph. CONCLUSIONS The mandibular condylar osteochondromas may show different growth positions encircling the condyle and exhibit varying shapes on panoramic radiograph. These features will help us to increase cognition of the lesion and make an exact diagnosis.

Abstract
Osteochondroma is rarely found in oral and maxillofacial regions. The majority of reported osteochondromas occurred in mandibular areas; their occurrence in bones developed by intramembranous ossification is extremely rare. In this report, a case of osteochondroma arising from the pterygoid process of the sphenoid is described. Radiological investigations showed a large bony mass under the left great wing of the sphenoid and involving the left parapharyngeal space. The tumour was compressive to the mandibular ramus and pharyngeal cavity, causing marked disturbance of mouth opening and secretory otitis media. Histopathological examination confirmed the lesion to be osteochondroma.
