RESUMEN
Agenesis of the temporomandibular condyle is a congenital/developmental disorder that can present with the absence of the condyle and an incomplete development of the articular fossa and eminence, resulting in facial asymmetry as well as masticatory dysfunction. The purpose of this report is to present the case of a three-year-old girl with absence of the left temporomandibular condyle. The patient presented with pain and dysfunction in the left masseter muscle, pre-auricular area and ear as well as mild chin deviation to the left. The most common treatment modality is to wait and treat this condition with surgical intervention once the patient is grown. However, oral orthopedic appliances can be considered to promote bone formation prior to surgery. Prompt recognition and early treatment is advisable to take advantage of the child's growth and avoid further facial asymmetry, pain and dysfunction.

For pediatric patients with refractory temporomandibular joint (TMJ) ankylosis, reconstruction with autologous techniques such as costochondral grafts or distraction osteogenesis has long been considered the gold standard. Many surgeons believed the use of alloplastic joint replacement to be contraindicated in pediatric patients due to concerns for growth restriction and the limited lifespan of the implants. However, recent data has supported TMJ prostheses in skeletally immature patients. This study aims to present a case series of pediatric patients undergoing bilateral TMJ reconstruction with custom-made implants and evaluate their postoperative results. A retrospective chart review was performed of all consecutive pediatric patients undergoing bilateral alloplastic TMJ reconstruction for refractory ankylosis. All patients underwent bilateral TMJ release and total joint replacement with custom-made implants. Preoperative and postoperative cephalometric and volumetric airway data was obtained using cone-beam computed tomography. Three patients, aged 8 to 17, underwent bilateral TMJ replacement with custom-made implants. There were no postoperative complications, and no implants required explantation or replacement. Postoperatively, all patients had increases in maximal interincisal opening, which was stable over months/years of follow-up. The patients also subjectively reported improved speech and mastication; 1 patient had significant improvements in sleep apnea symptoms. Volumetric airway analysis revealed an average airway size increase of 25.6%. Alloplastic TMJ reconstruction is a safe, effective solution for refractory ankylosis in pediatric patients and represents a promising new frontier in craniofacial surgery. Continued long-term evaluation will provide further evidence of the utility of this procedure.

Temporomandibular joint ankylosis (TMJA) secondary to congenital infiltrating lipomatosis of the face (CILF) is an exceptionally uncommon condition which is characterized by the involvement of unilateral facial soft tissues and bones. In some cases, the extensive exophytic bony growth in the temporomandibular joint region often extends toward the skull base and lies near adjacent vital structures. Only very few cases of TMJA associated with CILF have been reported in the literature. The authors report a case of a 36-year-old female with right TMJA secondary to CILF. The bony overgrowth in the right temporomandibular joint region was arising from a deformed right mandibular condyle, extending towards the ipsilateral temporal bone, greater wing of the sphenoid, skull base, and approaching the lateral limit of foramen ovale, and foramen spinosum. To prevent any damage to the skull base and adjacent vital structures and to achieve adequate mouth opening, the authors have performed a unique technique of subankylotic osteotomy for the release of TMJA, instead of conventional gap arthroplasty.

OBJECTIVE: To determine the clinical applicability of the modified concentric cannula technique (CCT), focusing on the duration of the arthrocentesis, the number of reposition of cannula, and the occurrence of complications. STUDY DESIGN: Descriptive study. Place and Duration of the Study: Department of Oral and Maxillofacial Surgery, Ankara Yildirim Beyazit University, Ankara, Turkiye, between September 2021 and May 2022. METHODOLOGY: Forty patients with Wilkes III temporomandibular joints (TMJ) internal derangement were identified and 13 patients who met the inclusion criteria were reviewed. The main outcomes regarding the clinical applicability of modified CCT included the duration of arthrocentesis, the number of reposition of cannula, and the occurrence of complications. RESULTS: The values of maximum mouth opening (MMO) without pain and MMO without assistance measured in the immediate postoperative period and at the 4th and 8th postoperative weeks were found to be significantly higher than the pre-arthrocentesis values. The values of MMO with assistance measured in the immediate postoperative period and at the 8th postoperative week were also significantly higher than the baseline values. Compared with preoperative values, notable decreases in pain scores were observed at the 4th (p = 0.003) and 8th (p = 0.002) postoperative weeks. The assessment of the jaw dysfunction also revealed significantly lower scores at the 4th (p = 0.024) and 8th (p <0.001) postoperative weeks. CONCLUSION: Modified CCT of arthrocentesis substantially decreased pain and improved mandibular functions in patients with internal derangement of TMJ. Additionally, this technique could be performed with a reduced number of cannula relocations and required a shorter operative time even with the use of a higher irrigation volume during the lavage procedure. KEY WORDS: Arthrocentesis, Temporomandibular joint disorder, Temporomandibular joint.

The purpose of the study was to determine whether the duration of preoperative pain affects outcomes of temporomandibular joint replacement (TMJR). Twenty-seven patients who underwent primary TMJR between 1 July 2020 and 31 October 2022 were retrospectively assessed for duration of preoperative pain, level of preoperative and postoperative pain on a visual analogue scale (VAS; 0, none; 10, severe), preoperative and postoperative range of motion (ROM), and net change in quality of life (much better, better, same, worse, much worse), reporting the longest available follow up for each patient. Surgical success was defined as postoperative pain of ≤4 and postoperative ROM of ≥30 mm, or net change (Δ) in ROM of ≥10 mm. Regression analyses evaluated associations between independent variables and postoperative pain and ROM. At a mean follow-up of 17.8 (SD: 6.8, range 3-32) months , pain (5.1, SD: 2.2, p < 0.001) and ROM (9.3 mm, SD: 8.0, p<0.001) significantly improved. Quality of life was much better in 16 patients, better in eight, the same in one, and worse in two. Longer duration of preoperative pain tended to be negatively associated with postoperative ROM (ß = -0.27; 95% CI -0.6 to 0.0; p = 0.078) but was not associated with severity of postoperative pain. Surgical success was achieved in 23/27 patients. The successful group tended to have lower pain on VAS preoperatively (5.9, SD: 1.9) vs 7.5, SD: 1.3) and postoperatively (0.4, SD: 0.8 vs 4.8, SD: 2.6), and greater improvement in quality of life (much better: 14/23 vs 2/4). In conclusion, longer duration of preoperative pain tended to be associated with worse postoperative ROM following TMJR. Higher preoperative pain may be a predictor for unsuccessful surgery.

Temporomandibular disorders (TMDs) are the second most common form of orofacial pain after an odontogenic source. Despite their complex aetiopathology they are considered a musculoskeletal disorder. They can have a significant impact on the quality of life of those suffering from TMDs, but can be treated and managed through a mixture of conservative and surgical approaches. Physiotherapists specialising in musculoskeletal therapy and pain management can offer a variety of techniques to help in the treatment and management of TMDs. In this narrative review the evolution of physiotherapy practice in the United Kingdom will be outlined, along with a discussion about physiotherapeutic theoretical frameworks in the management of musculoskeletal disorders and idiopathic TMDs. Finally, a narrative review will be presented, outlining the literature exploring the use of physiotherapy post TMJ surgery, underpinned by a systematic literature search on the topic. After screening for inclusion in the narrative review, eight articles were included for narrative synthesis. The main findings were that there is a relative paucity of studies looking at the value of physiotherapy post TMJ surgery compared with the treatment of idiopathic TMDs, and there is heterogeneity in the physiotherapy programmes described in the literature, but the addition of physiotherapy post TMJ surgery seems to augment the patient's response to surgery. The article concludes by describing the domestic challenges and opportunities of integrating physiotherapy into TMD management pathways.

Multiple techniques for disc fixation through temporomandibular joint arthroscopy have been described. They can be classified as non-rigid, semi-rigid, and rigid. They all offer different advantages and disadvantages, and some have greater difficulties than others. Currently, multiple modifications to the basic techniques have been described in order to facilitate the technique since disc fixation corresponds to one of the procedures that most require skill. However, each technique requires extensive evaluation and monitoring in order to avoid complications and find the benefits of each technique. For this reason, the objective of this letter to the editor is to discuss two situations observed in the previously described fixation technique with osteosynthesis screws. The first issue is the fixation mechanism, and the second is the fixation time. This is in order to continue searching for the truth among all to achieve the best results and the benefit of patients.

This study aimed to assess and compare the efficacy of two distinct single-puncture techniques in temporomandibular joint (TMJ) arthrocentesis for managing disk displacement without reduction (DDwoR). Sixty patients with DDwoR were randomly and blindly assigned to two treatment groups (n = 30 each): group 1 - TMJ arthrocentesis with the classic concentric needle; and group 2 - TMJ arthrocentesis with the concentric needle-cannula system. The following variables were recorded and compared across the groups: patient's pain perception (visual analog scale - VAS, 0-10); maximal interincisal distance (MID, mm); facial edema (FE, presence or absence); and operation duration (OP, minutes). Patients in group 2 presented significantly lower values of VAS score and presence of FE (p < 0.05) when examining the data at 24 and 48 h after the arthrocentesis. They also showed an increase in MID values (p = 0.024) after 6 months. With regard to OP, no significant difference was observed between the groups. Performing a single-puncture TMJ arthrocentesis using a concentric needle-cannula system significantly reduced the patients' pain perception, and mitigated the presence of facial edema during the immediate postoperative period (at 24 and 48 h). Furthermore, it resulted in a notable increase in the MID after 6 months.

The initial treatment of symptomatic disorders of the temporomandibular joint typically consists of a conservative approach, in which medication (painkillers and muscle relaxants), orofacial physiotherapy and splints are most important. In most cases, minimally invasive treatment options, such as arthrocentesis, arthroscopy or joint injections, are only considered when conservative methods provide insufficient symptom reduction. There is, however, an ongoing debate about the optimal treatment strategy due to an increasing body of evidence concerning the superior effectiveness in symptom reduction of minimally invasive treatment options with regard to conservative treatments. If these minimally invasive treatment options are also ineffective, open joint surgery may be considered as a last option for a select group of patients.

Temporomandibular joint (TMJ) arthrocentesis is one of the most commonly used non-invasive surgical interventions in the treatment of refractory pain and dysfunction associated with internal derangement. Several adjunctive therapies have been used in combination with arthrocentesis in an attempt to increase its efficacy and long-term maintenance. Duloxetine is a selective serotonin and norepinephrine reuptake inhibitor which is used in different chronic pain conditions. This study aimed to assess the efficacy of duloxetine in combination with arthrocentesis compared with arthrocentesis alone. Twenty-eight patients with chronic TMJ pain were included and randomly allocated into 2 groups (control and study groups). The control group included patients who underwent TMJ arthrocentesis only, and the study group included patients who underwent arthrocentesis followed by giving duloxetine (30 mg) orally twice daily for 3 months. Pain, maximum mouth opening, and level of anxiety and depression were assessed preoperatively and followed at regular intervals of 1 week, 1 month, 3 months, and 6 months postoperatively. Pain was significantly reduced in both groups at all postoperative intervals and was significantly lower in the study group than the control group at 6 months. Maximum mouth opening increased significantly in both groups, but the difference between them was not significant. Level of anxiety and depression was significantly decreased in both groups, with no statistically significant difference between them. The results of this study indicate that duloxetine in combination with arthrocentesis may provide effective and long-term pain control; however, its use is associated with a higher risk of adverse events.

OBJECTIVES: To evaluate the effects of costochondral grafting (CCG) used for temporomandibular joint ankylosis (TMJA) in growing patients. MATERIALS AND METHODS: Pediatric patients with TMJA treated by CCG from 2010.5 to 2021.7 were included in the study. CT scans were performed before and after operations with at least 1 year follow-up. The height of the mandibular ramus, menton deviation or retraction, osteotomy gap, etc. were measured by ProPlan CMF1.4 software. CCG growth, resorption, and relapse were evaluated and analyzed with influencing factors such as age, ostectomy gap, etc. by generalized estimating equation. RESULTS: There were 24 patients (29 joints) with an average age of 6.30 ± 3.13 years in the study. After operation, the mandibular ramus was elongated by 5.97 ± 3.53 mm. Mandibular deviation or retrusion was corrected by 4.82 ± 2.84 mm and 3.76 ± 2.97 mm respectively. After a mean follow-up of 38.91 ± 29.20 months, 58.62% CCG grew (4.18 ± 7.70 mm), 20.69% absorbed (2.23 ± 1.16 mm), and 20.69% re-ankylosed. The re-ankylosis was negatively correlated with the osteotomy gap (OR:0.348,0.172-0.702 95%CI, critical value = 6.10 mm). CCG resorption was positively correlated with the distance of CCG ramus elongation (OR:3.353,1.173-9.586 95%CI, critical value = 7.40 mm). CONCLUSIONS: An adequate osteotomy gap and CCG ramus elongation distance are the key factors for successful treatment of TMJA with jaw deformities in growing patients. CLINICAL RELEVANCE: TMJA affects mouth opening and jaw development in pediatric patients. The most common autogenous bone graft for pediatric patients is CCG due to its growth potential, convenient access and easy contouring. Also, it can simultaneously reconstruct the TMJ and improve jaw deformity by lengthening the mandibular ramus. But the growth of CCG is unpredictable. In this study, we explored several factors that may affect the absorption and re-ankylosis of CCG, expecting to provide several suggestions to improve future CCG treatment.

OBJECTIVE: Temporomandibular joint (TMJ) pathologies are prevalent, affecting approximately 40% of the worldwide population, with nearly 80% involving intracapsular disorders. Despite this, standardized treatment protocols are lacking. This study aimed to compare the efficacy of conservative and surgical approaches in managing intracapsular TMJ disorders. METHODS: Eighty-six patients diagnosed with intracapsular TMJ disorders were included in the study, with 40 males and 46 females, averaging 52.4 ± 4.7 years. Patients were recruited from polyclinics in Beijing, China (n = 36), and Kyiv, Ukraine (n = 50). A comprehensive examination protocol was conducted, including assessment of patient complaints, medical history, jaw mobility measurements, TMJ palpation, and magnetic resonance imaging (MRI) screening. RESULTS: The main outcomes of our study revealed significant improvements in patients undergoing surgical intervention for intracapsular TMJ disorders, particularly in cases of disc displacement. Conservative mouth guard/occlusal splint treatment showed limited effectiveness, primarily improving joint effusion and disc displacement. Surgical intervention led to notable enhancements in various TMJ parameters, with significant improvements observed in joint function and pain reduction. Based on these findings, orthodontic rehabilitation was recommended to ensure long-term efficacy, focusing on optimizing occlusion and restoring TMJ function. These results highlight the importance of tailored treatment approaches for managing intracapsular TMJ disorders, emphasizing the role of surgical intervention coupled with comprehensive rehabilitation strategies. CONCLUSIONS: Future research should consider demographic factors and explore innovative examination methods, such as optical systems, to enhance understanding and management of intracapsular TMJ disorders.

BACKGROUND: Current clinical approaches to regenerate temporomandibular joint (TMJ) articulating cartilage defects only treat the symptoms (i.e. pain and dysfunction) and do not seek to restore joint integrity for long-term relief. Therefore, we investigated a novel self-assembling tissue-engineered cartilage to overcome this significant clinical issue for TMJ regenerative purposes. OBJECTIVES: Examine the maturation of dynamic self-regenerating cartilage (dSRC) using auricular chondrocytes and evaluate a novel combinatorial approach with fractional laser treatment and dSRC implantation for TMJ cartilage repair. MATERIALS AND METHODS: A suspension of 107 freshly harvested rabbit ear chondrocytes was cultured under a continuous reciprocating motion to form the dSRC. After 2, 4 and 8 weeks of culture, dSRC samples were stained with H&E, Safranin-O and Toluidine Blue. Immunohistochemistry (IHC) was performed for collagens type I and II. Channels (300-500 µm diameter and 1.2-1.5 mm depth) were created in six freshly harvested condyles using a fractional Erbium laser. Two groups were tested: dSRC in a laser-ablated lesion (experimental) and an empty laser-ablated channel (control). TMJ condyles were cultured for up to 8 weeks and analysed as described above. RESULTS: H&E staining showed a high cell density in dSRC compared to native cartilage. All dSRC groups demonstrated intense Safranin-O staining, indicating high glycosaminoglycan (GAG) production and intense Toluidine Blue staining showed high proteoglycan content. IHC confirmed that dSRC consisted predominantly of collagen type II. The experimental group showed improved cartilage repair at both time points compared to the empty channels. CONCLUSION: dSRC viability and successful matrix formation were demonstrated in vitro. The combination of fractional laser ablation and dSRC implantation enhanced cartilage repair.

OBJECTIVE: To survey oral and maxillofacial surgeons (OMS) who perform temporomandibular joint replacement (TMJR) to determine whether length of surgery, specific TMJR protocols, or the incidence of complications are related to experience and case volume. STUDY DESIGN: An anonymous electronic survey was emailed to 407 surgeon members of the American Association of Oral and Maxillofacial Surgeons, American Society of Temporomandibular Joint Surgeons, and European Society of Temporomandibular Joint Surgeons known to have TMJR experience via publications or reputation. The descriptive survey contained multiple choice and open-ended questions. Descriptive statistics were computed for each variable for data analysis. RESULTS: Forty-nine surgeons completed the survey. The average stock TMJR cases included 54.6% unilateral and 50.5% bilateral cases. The average custom TMJR cases included 50.5% unilateral and 49.5% bilateral cases. Average procedure time for stock TMJR was 2.86 hours for unilateral, and 5.30 hours for bilateral cases. The average procedure time for a custom TMJR was 2.75 hours for unilateral, and 4.87 hours for bilateral cases. Average duration of hospital stay for stock and custom TMJR cases was 1.49 and 1.41 days (unilateral), and 1.98 and 1.95 days (bilateral). CONCLUSIONS: This study provides some pilot data that demonstrates that the length of surgery, specific TMJR surgical protocols, and the incidence of complications may be related to surgeon TMJR experience and case volume.

Tenosynovial giant cell tumor is a benign neoplasm arising from the synovium of joints, including the temporomandibular joint (TMJ). Despite its benign nature, these tumors may exhibit aggressive behavior. A 57-year-old woman with a swollen, hardened area in the left TMJ was referred to the university´s clinic. The diagnosis of tenosynovial giant cell tumor was made based on the presence of hyperplastic synovial lining containing mononuclear and giant cells, hemorrhagic areas, hemosiderin deposits, and calcification foci in the biopsy. A low condylectomy was performed, and histopathologic analysis of the surgical piece upheld the diagnosis. Due to histopathologic resemblance with other giant cell-rich lesions (giant cell granuloma of the jaws, brown tumor of hyperparathyroidism, and non-ossifying fibroma) for which signature mutations are known, mutational analysis of KRAS, FGFR1, and TRPV4 genes was conducted. The results revealed wild-type sequences for all the mutations tested, thereby supporting the diagnosis of tenosynovial giant cell tumor.

The purpose of this study was to assess the effects of protecting the facial nerve with a modified endaural approach with a peripheral dissection of the superficial musculoaponeurotic system to access the temporomandibular joint which allows an excellent operative field of visualization, multiple surgical procedures of the temporomandibular joint, and general care which improves the immediate postoperative period, making this a less morbid surgery. This study included 33 patients (39 sides) who underwent surgical treatment for disorders of the temporomandibular joint from the years 2021 to 2023 at the maxillofacial department of the clinic "Colsanitas" located in Bogota, Colombia. Therapeutic results were evaluated by postoperative facial nerve injury, with the House-Brackman scale; every patient was examined for adequate facial musculature function immediately after surgery. Notably, zero patients presented facial nerve injury. These results imply that the modified endaural approach with a peripheral dissection of the superficial musculoaponeurotic system to access the temporomandibular joint reduces the incidence of facial nerve injuries, improves operative site exposure, and lowers the frequency of complications.

Temporomandibular disorders include a wide spectrum of extra-articular and intra-articular conditions affecting the temporomandibular joint (TMJ). In salvage cases involving intra-articular end-stage disease, alloplastic temporomandibular joint replacement (TMJR) is a management option which can be utilised to rehabilitate a disabled joint's function and form. Whilst post-TMJR infection is rare, it is one of the most serious complications. The principles governing TMJR surgery antibiotic prophylaxis have been based on those established in orthopaedic surgery literature. Antibiotic resistance due to antibiotic over-use is a significant concern, therefore antibiotic stewardship has been developed to deal with this world-wide public health concern. The TMJ's anatomical proximity to the external auditory canal and oral cavity creates the potential for bacterial contamination. The aim of this study was to explore the views of 39 sub-specialist TMJ surgeons across nine nations usual approach to antibiotic prophylaxis and their management of TMJR infection. To accomplish this, an international survey was developed and conducted using Google Forms. The results demonstrated that 97.4% of the respondents employ prophylactic antibiotics at TMJR surgery, 83.8% on discharge. Variability in antibiotic choice with additional antimicrobial perioperative practices were also reported. Opinions on the management of a TMJR infection also varied. This survey establishes there is an agreement on the use of antibiotic prophylaxis, However the variability in choice, timing, course, duration of antibiotic use as well as the management of a postoperative TMJR infection demonstrates the need for further study leading to development of standardised antibiotic prophylaxis and infection management protocols for TMJR surgery.

The calcified chondroid mesenchymal neoplasm (CCMN) represents a recently recognized tumor type with only 50 well-documented cases in the English-language literature. Herein we report an additional case of CCMN presenting as a large mass in the temporomandibular joint region of a 41-year-old female. A review of previously reported cases and the current case of CCMN shows the following features: 1) average age 52 years (range 14-87 years) and an approximately even sex distribution; 2) most frequently involved sites: distal extremities (including foot, hand, wrist, forearm) (n=41) and temporomandibular joint/temporal/parotid region (n=9); 3) multilobular soft tissue tumor with chondroid to cartilaginous matrix, often grungy or lace-like calcifications, and variable cytologic atypia; 4) frequently detected FN1 rearrangement (n=15), including FN1 fusion with FGFR2 (n=7) or other receptor tyrosine kinases; 5) 2 reported local recurrences (after incomplete excision); 6) no reports of malignant biologic behavior.

This study assessed the current evidence for the use of TMJR reconstruction in skeletally immature patients. A systematic review was conducted according to PRISMA guidelines. An electronic search in PubMed and Embase was performed. Meta-analysis randomized controlled trials (RCTs), cohort studies, observational studies, case series, and case reports were eligible for inclusion. Case reports were also included due to the limited number of publications identified with the predefined terms. Exclusion criteria were: (1) studies written in a language other than English; (2) full-text unavailability (i.e., posters and conference abstracts). The selected studies were assessed for risk of bias. A meta-analysis was not performed as it necessitates a substantial between-study design homogeneity; hence, a descriptive synthesis of data was performed. There were 9 TMJR device reconstruction studies involving 14 subjects 13 years of age or younger. Follow-up ranged from 7 months to 120 months. All papers reported significant decrease in pain and improvement of diet. All prostheses were functional. No material failures of the prosthesis components were observed. The mandible continued to show limited growth following TMJR and most of the cases required no secondary or revision surgery even when the patient reached skeletal maturity. This systematic review had some limitations. The studies included had a low level of evidence and a high risk of bias. Most of the studies had a small patient sample, and no study had a control group. The literature reviewed supports the use of TMJR devices in the restoration of mandibular function and form in skeletally immature patients.
