Abstract
Background: Osteochondromas of the mandibular condyle show facial asymmetry and malocclusion. Because condylar osteochondromas are generally resected in a preauricular approach with risks of facial nerve injury and visible scar, the authors report endoscopically assisted intraoral resection of osteochondroma of the mandibular condyle with a piezoelectric surgical device.Case presentation: A 38-year-old woman presented with malocclusion and facial asymmetry caused by deviation of the chin to the left. Computed tomography showed a hyperdense, well-circumscribed mass arising from the medial aspect of the right mandibular condyle with resorption of the skull base. The patient underwent an endoscopically-assisted intraoral condylectomy with a piezoelectric surgical device. The postoperative course was uneventful without trismus, malocclusion, or facial asymmetry, and there was no recurrence 4 years after surgery.Conclusion:Endoscopically assisted intraoral resection of osteochondroma of the mandibular condyle with a piezoelectric surgical device is a minimally invasive and safe surgery.

Abstract
Surgical approaches in the treatment of TMJ pathologies are a much-debated topic in literature. We propose a new surgical approach performed by intraoral access and completed by endoscopic magnification and long-tip piezosurgery assistance. A piezosurgery (Piezosurgery Plus, Mectron s.p.a. 2014) with a long angled tip (MT5-10 L) was used to perform an endoscopically assisted condylectomy.

Abstract
In this study, 100 consecutive scheduled transoral condylectomies for unilateral condylar hyperplasia were included. The safety and surgical performances were assessed, using the operating time, conversion rate and complication rate. The conversion rate learning curve was evaluated with a learning curve cumulative summation (LC-CUSUM). The total conversion rate was 8.0%. The LC-CUSUM for conversion signaled at the 53th procedure, indicating sufficient evidence had accumulated that the surgeon had achieved competence. For procedures 54-100, the conversion rate was 4.0%. The operating time for the transoral condylectomy was 41.5 ± 15.3 min; when a conversion was necessary, the operating time was 101.4 ± 28.3 min (p < 0.05). The estimated operating time in the post-learning phase was 37 min, this was reached after approximately 47 procedures. There was 1 major complication of a permanent inferior alveolar nerve hypoesthesia. The complication rate was not significantly decreased after the learning curve. Within the limitations of the study, it seems that transoral condylectomy for UCH is a safe procedure with several advantages over the traditional preauricular approach. Surgeons starting this procedure should be aware of the potential complications and of the learning curve of approximately 53 procedures.

Int J Oral Maxillofac Surg 2021; 51:933-941. [PMID: 34972618 DOI: 10.1016/j.ijom.2021.12.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Revised: 12/16/2021] [Accepted: 12/17/2021] [Indexed: 10/19/2022]
Abstract
This study was performed to compare the effects on facial nerve (FN) function of the deep supra-temporalis muscle subfascial approach (DSFA) and traditional fascial approach (TFA) for access to the temporomandibular joint (TMJ), via qualitative and quantitative evaluations. Thirty patients requiring open TMJ surgery were randomly allocated to one of two groups: group A patients underwent the DSFA approach, while group B patients underwent the TFA approach. The TMJ was accessed via modified endaural incision with temporal extension. Clinical examinations, FN conduction tests, and electromyography (EMG) of the frontalis and orbicularis oculi muscles were used to assess FN function. A FN function deficit was noted in 50% of the whole sample population immediately after surgery, with no statistically significant difference between the groups (P = 0.082). Overall, 37.5% of the total study population experienced temporary loss of frontalis muscle activity, while zygomatic nerve injury was seen only in 25% of group A. Within 2-6 months, normal function returned in both groups. Nerve conduction studies showed no statistically significant difference between the groups in terms of nerve amplitude or latency after surgery. However, EMG of orbicularis oculi activity showed a significant difference between the groups after 6 months (P = 0.010). The results suggest that the traditional dissection approach is more protective of the FN, especially the zygomatic branch, than the deeper dissection technique.

Abstract
BACKGROUND Chondroblastomas, which account for approximately 1% of all bone tumors, typically occur in long bones, such as the femur, humerus, and tibia. However, in extremely rare cases, they may also occur in the craniofacial region where the tumor is often found in the squamous portion of the temporomandibular joint (TMJ) and in the temporal bone. CASE PRESENTATION This case report describes a large chondroblastoma (diameter, approximately 37 mm) that occurred in the TMJ. The tumor was sufficiently aggressive to destroy the TMJ, mandibular condyle neck, external auditory canal (EAC), mandibular fossa of the temporal bone, and facial nerve. The tumor was completely excised using a pre-auricular approach. The EAC and surgical defect were successfully reconstructed using a temporoparietal fascia flap (TPFF) and an inguinal free fat graft. There was no local tumor recurrence at the 18-month follow-up visits. However, the patient developed sensory neural hearing loss, and his eyebrow paralysis worsened, eventually requiring plastic surgery. CONCLUSION Large, invasive chondroblastomas of the TMJ can be completely removed through a pre-auricular approach, and the resulting surgical defect can be reconstructed using TPFF and free fat grafts. However, preoperative evaluation of the facial nerve and auditory function is necessary. Therefore, a multidisciplinary approach is essential.

Abstract
Condylar hyperplasia is an alteration in mandibular growth that can cause facial asymmetry and occlusal changes that usually affect the aesthetics and function of patients. To date, condylectomy for its part remains a key part of the treatment. Although there are still controversies regarding the amount of bone to remove and the surgical approach, there are still other concerns, such as finding the benefit in terms of intraoperative safety and postoperative results with different cutting devices, including the use of piezoelectric, which is increasing its use in the maxillofacial field. This is why the main objective of this study is to compare the results found in medical records and databases of condylectomy procedures performed between 2017 and 2019 with different cutting devices.

Abstract
With this research, we aimed to evaluate the effect of condylar osteochondroma (OC) resection through an intraoral approach on the masticatory functions. Resection of condylar OC was carried out via an intraoral approach with the help of three-dimensional (3D) design, endoscope, and navigation system. The T-Scan III computerised occlusal analysis system was used to evaluate the occlusal force distribution, recorded at pre-treatment (T1) and post-treatment (T2) intervals. Records of the clinical examination of the temporomandibular joint (TMJ), including maximal interincisal opening, mandibular lateral and forward movements, were also collected. Ten patients with condylar OC were enrolled in this study. The difference of force distribution between bilateral occlusion was reduced in T2 compared with T1 (11.92% ± 4.41% vs 48.52 % ± 28.37%, p<0.05), indicating better occlusal force distribution obtained after surgery. There was no significant difference in functions of the TMJ, such as maximal interincisal opening, and mandibular lateral and forward movements between T2 and T1 (p>0.05). Accordingly, condylar OC resection through an intraoral approach would obtain a satisfactory occlusal balance with no impairment of the temporomandibular joint functions.

Abstract
: A condylectomy of the mandibular condyle is considered to be the treatment of choice in most cases of condylar head hyperactivity. The aim of the procedure is to remove the growth center of the mandible which is responsible for the mandibular enlargement and asymmetry. This surgical procedure has an impact on the condyle shape and position, but the restoration of mandibular movement and a stable joint position (namely, the proper alignment of the newly shaped condylar head within the condyle fossa) should also be considered important surgical outcomes. In this article, the authors present their own experience in performing condylectomies with an arthroplasty procedure and a special forced suturing technique (FST) in terms of achieving early, accurate mandibular movement and maintaining a stable condyle position in early and late outcomes. MATERIALS AND METHODS A modified high condylectomy with arthroplasty and FST results had been studied in anatomical, radiological, and clinical model. RESULTS Early findings after FST are promising. A slight improvement in lateral jaw movement was noted after condylectomy with arthroplasty (P < 0.05) both in early and late follow-up. Incisal opening, mandibular protrusion, and lateral movement were sustained. A stable condyle position within the fossa was achieved in each case of condylectomy with arthroplasty (P < 0.05). CONCLUSIONS The FST condylectomy and reattachment of the lateral pterygoid muscle in a new, wider position provided an improvement in lateral jaw movement as well as in incisal opening and mandibular protrusion in early follow-up examination compared to the presurgical values. It seems that the FST enabled a better new condylar head position in the glenoid fossa and improved early functional mandibular movement.

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
Among the methods to treat temporomandibular joint (TMJ), preauricular, submandibular, retromandibular, and intraoral approaches have been described. These approaches, however, occasionally offer inadequate access, owing to the oblique course of the facial nerve, and access can be limited, especially to the medial and anterior part of the infratemporal fossa. The use of the transparotid approach can offer direct visualization of the facial nerves to prevent severe damage, and a wide work field can be achieved from the medial-anterior part of the infratemporal fossa to subcondylar region by retracting the mobilized facial nerves in either the superior or inferior direction. The 2 patients reported herein illustrate the addition of a transparotid approach to the standard procedures for the removal of an osteochondroma and condylectomy with displaced bone fragment for ankyloses of TMJ from the infratemporal fossa.

Abstract
INTRODUCTION The Risdon modified approach, for mandibular surgery, is well adapted to treatment of low subcondylar fractures. According to our experience, this approach with a low rate of complications should also be considered for non-traumatic ramus surgery. MATERIAL AND METHODS Twenty Risdon modified approaches were used in 11 patients for non-traumatic indications (seven bilateral osteotomies, four unilateral osteotomies, one biopsy, one bone graft). One patient was operated twice with the same approach. RESULTS In all cases, the planned surgery could be performed using this approach. The only complication was a case of temporary paresis of the facial nerve's mandibular branch. The scar was always considered as quite acceptable. DISCUSSION As for traumatology, the Risdon modified approach is an improvement for ramus non-traumatic surgery. It has a very low rate of complications, especially for the facial nerve. The intraoral approach avoids scarring, but the resulting exposure is insufficient and requires using a transcutaneous device or endoscopy. In orthognathic surgery, the wide exposure of the lateral aspect of the ramus, the corpus, and the basilar edge, facilitates important mandibular advancement.

Abstract
The use of endoscopes in oral and maxillofacial surgery has been well documented. The advantage of no external scar and minimal invasiveness makes endoscopic technique gradually more popular. This article will describe a rare case of an intraosseous inferior alveolar nerve schwannoma and its removal using endoscope. The surgical technique and preservation of the inferior alveolar nerve will be described and illustrated. The advantages and disadvantages of the approach will be discussed.
