Dimitroulis G. A guide for temporomandibular joint surgery using a simple surgical classification - A narrative-style review. J Craniomaxillofac Surg 2024:S1010-5182(24)00195-1. [PMID: 39019746 DOI: 10.1016/j.jcms.2024.06.012] [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: 03/23/2024] [Revised: 04/09/2024] [Accepted: 06/08/2024] [Indexed: 07/19/2024] Open
Abstract
The aim of this narrative style review is to clarify the role of TMJ surgery in the management of specific TMJ disorders by introducing a simple and practical surgical classification. A decade ago, a new surgical classification was published which, like the Wilkes classification, included the five escalating degrees of joint pathology, but with more practical definitions and proposed surgical options for each of the disease categories. The classification begins with Category 1 - painful but otherwise structurally normal joints, which are largely managed nonsurgically. Categories 2 and 3 denote reducing and nonreducing disc displacement of the TMJ, respectively, with the former treated by TMJ arthrocentesis or level 1 arthroscopy and the latter best managed with disc repositioning or discopexy. Category 4 describes degenerative changes to the disc itself, where the disc cannot be salvaged and is thus removed with TMJ discectomy. Lastly, Category 5 refers to end-stage joint disease, where none of the joint components can be salvaged; both the disc and condylar head are sacrificed, and the TMJ is reconstructed with a prosthetic total joint replacement. In the decade since its publication, various studies have served to validate the usefulness of the TMJ surgical classification, and how it can be applied to better understand the role of TMJ surgery in everyday clinical practice.

Abstract
The understanding of the causes of temporomandibular joint pain and dysfunction has evolved over 50 years. Historically, the term internal derangement has been used to describe the abnormal relationship between the articular disc, condyle, and glenoid fossa, which was thought to correlate with patient symptoms. It is now known that the pathophysiology of intra-articular pain and dysfunction (IPD) involves synovitis, capsular impingement, symptomatic disc displacement, or a combination of these. Symptomatic disc displacement should only be considered to be a potential source of IPD after synovitis and capsular impingement have been treated. This philosophy provides the opportunity for most patients with IPD to be initially treated nonsurgically or with minimally invasive procedures such as arthrocentesis or arthroscopy.

[PMID: 38601224 PMCID: PMC11001795 DOI: 10.1007/s12663-022-01815-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Accepted: 10/17/2022] [Indexed: 04/12/2024] Open
Abstract
Aim To identify the optimal depth of penetration required to access the superior joint space (SJS) for arthroscopic procedures of the temporomandibular joint (TMJ) among the study population. Materials and Methods The study included all patients with internal derangement (ID) of the TMJ, managed by TMJ arthroscopy in our institution. The study was conducted with data retrieved from the hospital records over five years (January 2018-April 2022). Demographic factors and depth of penetration (mms) were the variables included in our study. For all the statistical interpretations, p < 0.05 was considered statistically significant. Results The study included 66 patients (males, n = 25; females, n = 41) who underwent arthroscopic procedures of the TMJ (right = 29, left = 37). The mean duration between the development of symptoms and the point of intervention (TMJ arthroscopy) in our study was 3.94 months. The mean depth of penetration of the arthroscope as measured from the skin to the point of entry into the SJS was 20.60 ± 1.85 mms in males and 19.56 ± 1.38 mms in females (p value < 0.05). Variables such as age, duration of symptoms, side involved and stage of ID did not have any influence on the optimal depth of penetration required to access the joint space among our study population. Conclusion The optimal depth of penetration (mean) required to access the SJS was less than 25 mms in our study population.

Abstract
OBJECTIVE Evaluate the efficacy of bilateral temporomandibular joint (TMJ) arthroscopy in patients with different categories of severity based on Dimitroulis classification (categories 2-4) and the role of a second TMJ intervention in primary failure. METHODS A 3-year prospective study was designed, including patients submitted to bilateral TMJ arthroscopy. The primary outcome was TMJ pain (VAS, 0-10) and the secondary outcomes were the maximum mouth opening (MMO) and masticatory myalgia degree (0-3). In cases of symptomatic relapse, a second TMJ intervention was performed (TMJ arthrocentesis or TMJ open surgery). RESULTS Eighty patients (93.4% women) were enrolled, with a mean age of 32.40 ± 11.41 years. With an average follow-up of 523.7 days (34-1606), a statistically significant improvement in TMJ pain, MMO, and myalgia degree was observed (P < 0.0001). The overall successful outcome of one-single bilateral arthroscopy was ~ 69%. Twenty-two patients relapsed: (1) arthralgia (n = 15, 68.18%); (2) arthralgia + myalgia (n = 4, 18.18%); (3) dislocated disc without reduction (DDwoR) (n = 2, 9.09%); (4) DDwoR + osteoarthrosis (OA) (n = 1, 4.55%). Arthralgia was re-managed with TMJ arthrocentesis with local anesthesia (n = 19, 86.36%). New DDwoR with or without OA was re-treated with TMJ open surgery (n = 3, 13.64%). After the second intervention, the success rate increased to 85%. CONCLUSIONS Bilateral TMJ arthroscopy presented overall benefit in all parameters evaluated. CLINICAL RELEVANCE This study highlights the importance of TMJ arthroscopy as the first line of treatment for moderate-severe temporomandibular disorders cases contributing to the reduction of TMJ open surgeries. In cases of arthroscopy unsuccess, TMJ arthrocentesis under local anesthesia was an effective and safe intervention for patients with recurrent TMJ arthralgia.

Abstract
The aim of this study was to evaluate the efficacy of suprafoveal condylar arthroplasty (SFCA) in the management of patients with unilateral temporomandibular joint (TMJ) disc displacement without reduction (DDWoR). A retrospective study comprising patients who underwent unilateral SFCA for clinically and radiologically confirmed unilateral DDWoR from 2008 to 2020 was conducted. Patients older than 18 years at the time of diagnosis with a minimum of 6 months of unsuccessful non-surgical and minimally invasive management (including diet and life style modification, physiotherapy, appliance therapy, pharmacotherapy, arthrocentesis and arthroscopic lysis and lavage) before undergoing surgery with a minimum of 1 year follow-up post-surgery were included in the study. Patients with other articular and extra-articular causes of restricted mouth opening, prior history of mandibular surgery and/or trauma, growth abnormalities, systemic, metabolic, infective, neoplastic conditions affecting TMJ, including gross occlusal disharmony, untreated existing para-functional habits and bilateral DDWoR, were excluded from the study. Patients were assessed in terms pain on a visual analog scale (VAS), interincisal mouth opening (MO) and subjective assessment of mandibular range of movements including deviation of mouth opening, protrusion and ability for contralateral laterotrusion. 23 patients (10 males and 13 female) were included in the study, with a mean age of 35.09 years and mean follow up period of 37.7 months (range = 12-58; SD = 15.3). The mean pain scores on the VAS reduced from 6.35 preoperatively to 1.13 postoperatively and were found to be statistically significant (p < 0.0001). The improvement of the mean pre-operative mouth opening of 21.83 mm to a mean post-operative mouth opening of 42.09 mm was also found to be statistically significant (p < 0.0001). The subjective improvement in protrusive (p = 0.0003), laterotrusive (p = 0.0005) and opening movements (p = 0.0001) after 1 year were also found to be statistically significant. No patient developed any significant changes in occlusion post-operatively. Four of 23 (17.3%) patients developed transient neuromotor deficit of the temporal branch of the facial nerve. Within the limitations of the study, it seems that SFCA (without addressing the disc) might be an alternative to less invasive treatment approaches, if the latter turned out not to be successful.

Current Treatment Strategies for the Management of the Internal Derangements of the Temporomandibular Joint: A Global Perspective. J Maxillofac Oral Surg 2022; 21:1-13. [PMID: 35400919 PMCID: PMC8934796 DOI: 10.1007/s12663-021-01509-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Accepted: 01/04/2021] [Indexed: 10/22/2022] Open
Abstract
Internal joint derangement is a disruption of the internal aspects of the TMJ-disc displacements/adhesions/impingements, causing alterations in the normal dynamic motions of the joint. Clinicians must be diligent in establishing the correct diagnosis and cause of TMJID, which ultimately leads to the appropriate management of such patients. While many patients adapt over time or with non-surgical treatment, surgery may be indicated for those with ongoing problems. The surgical pyramid provides a stepwise progression for TMJ surgical patients. This paper aims to review TMJID and its management with special emphasis on arthroscopic minimally invasive surgery, as practised in other countries around the world, and compare this to current education, understanding and practice in India. Currently, India is lagging behind in providing the full scope of TMJ services as there are very few surgeons trained in the skill of arthroscopic techniques. There needs to be continued expansion of our understanding of TMJID treatment in India to bring it level with the rest of the world.

JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2021; 122:e21-e26. [PMID: 33845189 DOI: 10.1016/j.jormas.2021.03.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/05/2020] [Revised: 02/18/2021] [Accepted: 03/11/2021] [Indexed: 11/18/2022]
Abstract
INTRODUCTION Arthroscopic treatment of the temporomandibular joint (TMJ) has traditionally been evaluated with clinical measurements. Additional recordings of patient reported outcome measures (PROM) is expected to make the evaluation more complete. The aim of the study was to evaluate if PROM correlates with clinical follow-up measures after arthroscopic treatment of internal derangement of the TMJ. MATERIAL AND METHODS Patients with temporomandibular dysfunction (TMD), treated with arthroscopic lysis and lavage of the TMJ, were followed with a PROM questionnaire; Jaw Functional Limitation Scale 20 (JFLS-20) and a review of patient medical records. Out of 239 patients treated, 134 were eligible for inclusion to the study. RESULTS 91 subjects, 21 males and 70 females, with mean age 42.6 years completed the follow-up. The JFLS-20 mean score was 25.43 (range: 0-148). A correlation was found between JFLS and mouth opening. The JFLS-20 score was decreased by 1.48 (p = 0.0001) for ever millimeter larger mouth opening and with 1.16 (p = 0.001) for every gained millimeter of mouth opening after arthroscopic treatment of the TMJ. The mean maximal mouth opening was 38.43 mm preoperatively (15 to 75 mm) compared to 42.19 mm postoperatively (range: 21-75 mm). A total of 80 subjects with TMD associated pain preoperatively was reduced to 25 postoperatively (p = 0.0001). DISCUSSION Advantageous treatment effect with arthroscopic lysis and lavage was presented. The outcome of the JFLS-20 questionnaire indicates a correlation with the clinical findings. Future studies will focus on larger cohorts and using PROM with a case-control setting.

[PMID: 33442809 DOI: 10.1007/s10006-020-00935-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Accepted: 12/14/2020] [Indexed: 10/22/2022]
Abstract
PURPOSE The aim of this study was to determine the efficacy of arthroscopic lysis and lavage on pain in patients with unilateral Wilkes stage III derangement of the temporomandibular joint. Authors retrospectively evaluated whether the arthroscopic lysis and lavage has an impact on pain decrease in patients with moderate osteoarthritis. METHODS Patients with unilateral Wilkes III of temporomandibular joint were included in this study. All patients underwent arthroscopic lysis and lavage (ASC-L), assessed pain before and after the procedure (primary outcome variable), maximal interincisal opening (MIO) was recorded as secondary outcome variable. The patients also subjectively assessed whether they were satisfied with the outcome of the arthroscopy or whether their condition required further interventions. The disc position was evaluated by magnetic resonance imaging (MRI) 24 months after the arthroscopy and compared with the disc position on the MRI prior to the arthroscopy. The R Project for Statistical Computing 3.4.1 and the Gretl Pro programs were used for statistical analysis. In addition to the descriptive statistics methods, the Shapiro-Wilk normality test was used to verify data normality and the two sample t test used to test the hypotheses themselves. RESULTS The sample consisted of 62 patients who underwent arthroscopic lysis and lavage (ASC-L) in 2015 and 2016. It included 6 men and 56 women with an average age of 34.37. Pain and MIO were recorded during regular check-ups 1, 3, 6, 12, and 24 months. A therapeutic effect (MIO over 34 mm, VAS score 0-1) was recorded in 69% of cases 24 months after the ASC-L. Nonetheless, the work demonstrated the importance of subjective assessment, as 87% of patients perceived their condition as satisfactory after 24 months and not requiring further intervention, while 8 patients (13%) perceived it as unsatisfactory. Disc reposition 24 months following the ASC-L was recorded in only 44% of patients who assessed their condition as satisfactory. Patients with persistent disc dislocation 24 months after the arthroscopy were older, had a lower average maximal interincisal opening value before the ASC-L and a longer duration of mandibular movement restriction before the ASC-L (evaluated as a statistically significant difference). CONCLUSION In this study, the authors confirmed that ASC-L is an effective therapeutic method in patients with WIII, from both clinical and subjective perspectives. This work demonstrated that improvement in patients with Wilkes stage III is not related to disc reposition. Postoperative physiotherapy is an integral component of ASC-L and is reflected in the final results.

Abstract
Disorders of the Temporomandibular joint (TMJ) may clinically present with jaw pain and restricted mouth opening that may limit a patient's access to comprehensive dental care. The aim of this article is to provide a general overview of the current treatment strategies available in the management of disorders of the TMJ. Both conservative and surgical treatment options will be discussed as there is no one treatment for temporomandibular disorders (TMD) which encompasses a wide range of diagnoses. A multidisciplinary team approach to management is essential in the fundamental care of all TMD patients so that treatment can be specifically tailored to individual patient needs.

Abstract
Improving the outcomes of surgical treatment of the temporomandibular joint (TMJ) is beneficial from a patient and health-economy perspective. Optimizing conditions for a successful result can be reached using validated, strict diagnostic criteria and by identifying patient-specific factors predicting the outcome. The aim of this study was to investigate possible predictive factors in TMJ arthroscopy. A prospective cohort study including 93 patients undergoing arthroscopy was conducted. The outcome was graded as successful (53%, n=49), good (25%, n=23), intermediate (20%, n=19), or deteriorated (2%, n=2) using a predefined set of objective and subjective outcome measures. The outcome was correlated with preoperative and perioperative variables and the diagnosis. Preoperative bilateral masticatory muscle tenderness on palpation was the only variable significantly correlated with a negative outcome in the adjusted regression analysis (odds ratio (OR) 2.56, P=0.048). Low age (OR 1.03, P=0.05) and bilateral joint surgery/operated side (OR 0.24, P=0.05) were found to correlate with an unsuccessful outcome in the unadjusted analysis. Eighty-nine percent of the patients with osteoarthritis benefited from arthroscopy, while corresponding figures were 80% for disc displacement without reduction and 64% for chronic inflammatory arthritis. Preoperative bilateral masticatory tenderness might be a useful predictive factor suggesting the consideration of revised non-invasive therapy before surgery.

Abstract
PURPOSE This review aimed to examine whether the anchored disc phenomenon (ADP) is truly a distinct entity, independent of the closed-lock condition attributed to nonreducible disc displacement. MATERIALS AND METHODS Clinical and/or diagnostic imaging studies addressing the anchored disc or ADP were considered. Articles eligible for inclusion were written in English; were conducted in humans; showed, in their titles or abstracts, any of the keywords used in the search method; included some type of disc imaging system; and related disc mobility to disc position. Of 18 potentially relevant articles, 10 were included. RESULTS Of the studies, 9 used magnetic resonance imaging and 1 used double-contrast cone-beam computed tomography. In 1,691 joints, 270 discs (16%) were shown to be anchored in a normal (41%) or displaced (59%) position. Of 149 displaced anchored discs, 52 were reducible and 97 were nonreducible. Intra-articular adherences, synovitis, and adhesions were common arthroscopic findings in patients with the ADP. CONCLUSIONS The temporomandibular joint anchored disc shown by disc imaging systems is worthy of inclusion in the existing categories of temporomandibular joint internal derangement. Classification of the ADP as a distinct entity still awaits a consensual definition of the problem, validation of the underlying hypothesis, and clarification of the natural history of the phenomenon.

Does injection of plasma rich in growth factors after temporomandibular joint arthroscopy improve outcomes in patients with Wilkes stage IV internal derangement? A randomized prospective clinical study. Int J Oral Maxillofac Surg 2016; 45:828-35.

Abstract
The aim of this study was to evaluate the efficacy of injection of plasma rich in growth factors (PRGF) after temporomandibular joint (TMJ) arthroscopy in patients with Wilkes stage IV internal derangement. Ninety-two patients were randomized to two experimental groups: group A (42 joints) received injections of PRGF, group B (50 joints) received saline injections. Pain intensity on a visual analogue scale (VAS) and maximum mouth opening (MMO, mm) were measured before and after surgery and compared by analysis of variance (ANOVA). The mean age of patients was 35.8 years (range 17-67 years); 86 were female. Significant reductions in pain were noted in both groups after surgery: VAS 7.9 preoperative and 1.4 at 24 months postoperative. Significantly better clinical results were achieved in group A than in group B only at 6 and 12 months postoperative; no significant difference was noted at 18 or 24 months after the surgical intervention. MMO increased after surgery in both groups: 26.2mm preoperative and 36.8mm at 24 months postoperative. No significant differences in MMO were found when the two groups of patients were compared. In conclusion, the injection of PRGF does not add any significant improvement to clinical outcomes at 2 years after surgery in patients with advanced internal derangement of the TMJ.

Abstract
Several open surgeries have been proposed for the treatment of internal derangement (ID) of the temporomandibular joint (TMJ), although minimally invasive temporomandibular joint surgery (MITMJS) plays a major role in the treatment of ID and has been widely used for the treatment of ID of the TMJ. Arthrocentesis, arthroscopic lysis and lavage, and operative or advanced arthroscopy are the 3 most relevant techniques for MITMJS; clear indications for their application and a detailed description of each technique are presented. Also, clinical outcomes for each technique from the most relevant studies in the literature are reported.

Abstract
INTRODUCTION Internal derangements (ID) of the temporomandibular joint (TMJ) have a multifactorial etiology and are most often treated conservatively by splints, physical therapy and medications. Only in 2-5% of cases are the treatment surgical, either by arthroscopy or arthrotomy. OBJECTIVE To evaluate improvement of mouth opening, pain relief during function, position of the articular disk and complications following Arthroscopic Lyse and Lavage (ALL). METHODS A prospective study of 78 patients (138 TMJs) with TMJ ID, 5 males and 73 females, mean age 29.7 years, treated between January 2010 and April 2013, who were refractory to conservative treatment, had limited mouth opening and pain localized to the TMJ during function, and who were submitted to TMJ ALL and followed for a period of 12 months, with periodic reviews. RESULTS ALL was effective in 93.6% of cases, with 85.3% experiencing improvement in mouth opening and 91.2% in pain reduction during function, 63% improvement in disk position and a rate of complications of 6.2%. CONCLUSION In this study the ALL exhibited a high rate of success with low morbidity in internal derangements of the TMJ.

Abstract
AIM This study aimed to carry out a case-control research study to assess occurrence of clicking of the temporomandibular joint (TMJ) in order to establish the relationship between TMJ clicking and the genotype of "ANKH inorganic pyrophosphate transport regulator" (ANKH) polymorphisms. MATERIALS AND METHOD A sample of 41 first-year dental residents was selected. Each was examined using standard clinical procedures and genotyping techniques. RESULTS The participation rate was 91.8 %. The prevalence of TMJ clicking was 51.2 % (95 % CI: 35.7-66.7 %). Occurrence of TMJ clicking was not related to age, gender and genotypes of ANKH-OR as well as ANKH-TR polymorphisms (p ≥ 0.165). CONCLUSION A similar distribution of ANKH genotypes in TMJ clicking and asymptomatic individuals has been demonstrated by this study. A high percentage of TMJ clicking has been confirmed. Future investigations are indicated.

Abstract
This case report describes the orthodontic treatment performed for open bite caused by internal derangement (ID) and osteoarthritis (OA) of the temporomandibular joint (TMJ). A Japanese woman, aged 31 years and 11 months, referred to our department by an oral surgeon had an open bite with clockwise rotation of the mandible and degeneration of the condyle. The overbite was corrected through intrusion of the maxillary and mandibular molars using mini-screw implants to induce counterclockwise rotation of the mandible. Then, the mandibular second premolars were extracted and comprehensive orthodontic treatment was performed to establish a Class I molar relationship with distalization of the maxillary arch and to eliminate anterior crowding. Following treatment, her facial profile improved and a functional and stable occlusion was achieved without recurrence of the TMJ symptoms. These results suggest that orthodontic intrusion of the molars is one of the safer and less stressful alternatives for the management of open bite due to degeneration of the condyles caused by ID and OA of TMJ.

Abstract
The aim of this retrospective clinical study was to assess the clinical outcomes of temporomandibular joint (TMJ) arthroscopy in patients who presented with category 1 normal joints. The null hypothesis being tested was that patients with normal joints do not respond to TMJ arthroscopy. The clinical records of 116 patients who had undergone TMJ arthroscopy by the author from 2010 to 2013 were retrieved and individually analysed for inclusion in this retrospective, cohort clinical study. The inclusion criteria used to select patients for this study were those who had arthroscopically proven category 1 normal joints, free of intra-articular pathology. Of the 14 patients who were found to have normal joints, only 10 could be contacted for a follow-up survey. Despite the fact that all patients were informed that no joint pathology was found, six out of the 10 patients reported improvement in their temporomandibular disorder (TMD) symptoms that lasted for more than 6 months following TMJ arthroscopy. The results of this investigation indicate that we can reject the null hypothesis, and that patients with normal TMJs do indeed respond to TMJ arthroscopy. What this limited study has highlighted is the pervasive effects of the placebo that all surgeons need to keep in mind when formulating treatment plans for patients with TMD.

Abstract
Temporomandibular joint (TMJ) 'closed lock' (CL) is a clinical condition causing TMJ pain and limited mouth opening (painful locking) that is mostly attributed to disc displacement without reduction (DDwoR), or less commonly to anchored disc phenomenon (ADP). Both conditions are described clinically as CL that can be 'acute' or 'chronic' depending on the duration of locking. There is, however, no consensus about the duration of locking that defines the acute state and its effect on the success of interventions. This review paper, therefore, aims to provide: (i) a narrative review of the pathophysiological need for early intervention in DDwoR and the clinical implications of acute/chronic CL stages on the management pathway; (ii) a systematic review investigating the effects of locking duration on the success of interventions for CL management. Electronic and manual searches until mid-August 2013 were conducted for English-language studies of any design investigating the effects of non-surgical and surgical interventions for acute or chronic CL (DDwoR or ADP). A total of 626 records were identified, and 113 studies were included. Data extraction and quality assessment were completed for all included studies. Included studies were, however, heterogeneous and mostly of poor-quality leading to contradictory and inconsistent evidence on the effect of the duration of locking on treatment outcomes. Future high-quality trials investigating the effect of CL duration on treatment outcome are needed. At present, early intervention by 'unlock' mandibular manipulation seems to be the most practical and realistic approach that can be attempted first in every CL patient as an initial diagnostic/therapeutic approach.

Abstract
PURPOSE Disc perforation (DP) is one of the most important pathologic signs of intracapsular temporomandibular joint (TMJ) disease; however, few clinical studies have focused on the arthroscopic management of this feature. The purpose of the present study was to assess whether operative arthroscopy with abrasion of the perforation borders is effective for the treatment of this alteration of the internal derangement of the TMJ. PATIENTS AND METHODS Thirty-six patients (39 joints) who underwent TMJ arthroscopy under general anesthesia and presented with DP (Wilkes stages IV and V) from 1994 through 2006 were included in this study. The age range at the time of surgery was 14 to 59 years. DPs were classified into 3 groups according to size: small (SMA), medium (MED), or large (LAR). Pain (visual analog scale, scores 0 to 100), maximal interincisal opening, and lateral and protrusive excursions were assessed at 1, 3, 6, 12, 24 and 48 months after surgery. Preoperative and postoperative scores were compared and tested for statistically significant differences by the Student t test for paired data. The level of statistical significance was set at .05. Differences in the global, SMA, MED, and LAR groups were evaluated. RESULTS In the global group, the mean score of preoperative pain according to the visual analog scale was 53.97 mm, which decreased to 14.33 mm at 4-year follow-up. The maximal interincisal opening improved from a mean of 28.56 mm before surgery to 34.88 mm after the final follow-up. SMA perforations were found in 11 cases (28.20%), MED in 19 cases (48.71%), and LAR in 9 cases (23.07%). A significant decrease in pain (P < .01) was observed from the first postoperative month to the end of the follow-up period in the global and SMA groups. A statistically significant increase in mouth opening was observed in the global group from 6 months postoperatively; however, no significant differences were observed in the MED and LAR groups from before surgery to the different times of follow-up. After the final follow-up, 2 patients underwent open TMJ surgery owing to unfavorable results. CONCLUSIONS Operative arthroscopy of the TMJ is a reliable and effective procedure for the articular dysfunction associated with DP because this procedure alleviates pain and improves mouth opening. Patients with SMA perforations are better candidates for this surgical treatment.

Abstract
While India boasts the largest collective experience in the surgical management of TMJ ankylosis, times are changing and Indian Surgeons will need to begin thinking about other TMJ disorders that have previously gone under the radar. A growing Indian middle class with greater access to health facilities will demand treatment for TMJ disorders like myofacial pain and dysfunction, internal derangement and osteoarthrosis which Oral & Maxillofacial Surgeons must be prepared to manage. The aim of this paper is to review the role of TMJ surgery and its place in the treatment armamentarium of temporomandibular disorders. Indications, rationale for surgery, risks vs benefits are discussed and complemented with examples of clinical cases treated by the author. As India moves up the economic ladder of success, TMJ disorders that have largely been confined to Western nations will begin to appear in the rising middle classes of India. Indian Oral & Maxillofacial Surgeons must be prepared to recognize and manage disorders which present with more complex symptomatology where the role of TMJ surgery is less clear cut.

Abstract
Introduction: Internal Derangement of the Temporomandibular Joint is an intra-articular condition in which there is a disruption in the normal relationship of the articular disc to the articular eminence and the condyle when the joint is at rest or in function. Patients may complain of pain and/or limitation of mouth opening. Treatment of internal derangement of temporomandibular joint includes arthrocentesis and arthroscopy. The aims of this retrospective study are to examine the efficacy of arthrocentesis and arthroscopy in the treatment of internal derangement of temporomandibular joint, specifically in relation to joint movement and pain. Methods: Twenty consecutive patients with internal derangement of temporomandibular joint seen in National Dental Centre of Singapore, from 2010 to 2011, were included in this study. Nine patients underwent arthrocentesis and 11 had arthroscopic lysis and lavage. The pre and postoperative pain score, in Visual Analogue Scale (0 to 10) and maximal inter-incisal opening were recorded to evaluate the effectiveness of both treatment modalities. The patients were reviewed one week and one month post-operation. The data obtained were statistically analysed. Results: Significant increase in postoperative mouth opening and reduction in pain were found in both groups of patients. In the arthrocentesis group, the mean increase in maximal inter-incisal opening was 13 ± 5mm and reduction of pain in VAS was 4.56 ± 1.74. For the arthroscopy group, the mean increase in maximal inter-incisal opening was 6.6mm ± 4.8mm and the reduction of pain was 2.5 ± 2.2. Duration of symptoms prior to treatment appeared to have influenced the treatment outcome of both treatments. Conclusion: Arthrocentesis and arthroscopy are effective in the treatment of internal derangement of temporomandibular joint. Factors that may influence treatment outcomes need to be investigated to provide more information on the predictability of arthrocentesis and arthroscopy.

Abstract
A poor appreciation of the role of surgery in the management of temporomandibular disorders (TMD) may result in some patients being denied access to appropriate care. While surgery is often considered as an option of last resort, there are instances where surgery is the definitive and sometimes the only treatment option. The aim of this paper was to review the role of temporomandibular joint (TMJ) surgery and its place in the treatment armamentarium of temporomandibular disorders. Indications, rationale for surgery, risks vs. benefits are discussed and complemented with examples of clinical cases treated by the author. All dental practitioners should be aware of the benefits of TMJ surgery so that patients do not suffer unnecessarily from ongoing non-surgical treatments that ultimately prove to be ineffective in the management of their condition.

Abstract
Objectives This study aimed to carry out a histological examination of the temporomandibular joint (TMJ) in ank mutant mice and to identify polymorphisms of the human ANKH gene in order to establish the relationship between the type of temporomandibular disorders (TMD) and ANKH polymorphisms. Materials and Methods Specimens from the TMJ of ank mutant and wild-type mice were inspected with a haematoxylin and eosin staining method. A sample of 55 TMD patients were selected. Each was examined with standard clinical procedures and genotyping techniques. Results The major histological finding in ank mutant mice was joint space narrowing. Within TMD patients, closed lock was more prevalent among ANKH-OR homozygotes (p = 0.011, OR = 7.7, 95% CI 1.6–36.5) and the elder (p = 0.005, OR = 2.4, 95% CI 1.3–4.3). Conclusions Fibrous ankylosis was identified in the TMJ of ank mutant mice. In the human sample, ANKH-OR polymorphism was found to be a genetic marker associated with TMJ closed lock. Future investigations correlating genetic polymorphism to TMD are indicated.

Abstract
The authors prospectively analysed 50 patients with chronic anterior disc displacement without reduction, who underwent arthroscopic lysis and lavage of the temporomandibular joint (TMJ). Patients with symptoms lasting less than 1 year were assigned to Group A (n=28) and patients with symptoms lasting more than 1 year to Group B (n=22). The most common problems were inflammatory changes of synovial and retrodiscal tissue (Group A, 71%; Group B, 82%). Fibrous adhesions were present in 14% of Group A patients and 45% of Group B patients. Degenerative changes of the disc and articular surface were present in 4% of Group A patients and 32% of Group B patients. Mouth opening increased 123% from baseline in Group A, and 112% in Group B (P<0.05). Pain decreased significantly in both groups (Group A, 2.5 points; Group B, 1.68 points; P<0.05). In conclusion, almost all patients with chronic anterior disc displacement without reduction benefited from arthroscopic lysis and lavage of the TMJ. Patients with a shorter duration of symptoms problems benefited more than those with a longer duration. Arthroscopic lysis and lavage of the TMJ is safe and beneficial in chronic anterior disc displacement without reduction.

Abstract
PURPOSE Among patients with Wilkes stage III and IV disease undergoing arthroscopic lysis and lavage, does the use of an intra-articular injection of sodium hyaluronate (SH), when compared with Ringer lavage, result in better postoperative pain control and temporomandibular joint (TMJ) function? PATIENTS AND METHODS We designed and implemented a randomized, double-blind, pilot controlled clinical trial. The study sample was composed of patients with middle Wilkes stage (late stage III and early stage IV) disease. Subjects were randomized to 1 of 2 treatment limbs. The treatment group received Ringer lactate plus an injection of 1 mL of SH after arthroscopy, whereas the control group was given Ringer lactate during arthroscopy. The primary outcome variables were pain and TMJ function measured by use of visual analog scales. Appropriate descriptive and bivariate statistics were computed. A P value less than .05 was considered statistically significant. RESULTS The study sample was composed of 40 patients with 20 subjects enrolled in both treatment groups. There were no statistically significant differences between the 2 groups in terms of demographics and preoperative variables. Postoperative analgesia was statistically significant in the treatment group with respect to the control group on the visits on days 14 and 84. No statistically significant differences were observed between the 2 groups in the maximum interincisal opening and tolerance. CONCLUSIONS An intra-articular injection of SH after arthroscopic lysis and lavage is effective in reducing pain in patients with TMJ dysfunction, enhancing postsurgical recovery. The analgesic effect of treatment with SH is maintained in the long term.

Abstract
OBJECTIVE The article shows the 1-yr results comparing the efficacy of open-surgery high condylectomy and disc repositioning and the arthroscopic procedure of lysis, lavage and capsular stretch in patients with chronic closed lock of the temporomandibular joint (TMJ). STUDY DESIGN Twenty patients with a clinical and radiologic diagnosis of chronic closed lock were randomly chosen to be treated with either open surgery or arthroscopy. Each patient was evaluated with a visual analog scale (VAS) for pain and a mandibular functional impairment questionnaire (MFIQ). The evaluation also included a clinical examination. Each patient was recorded at baseline before surgery and at 1-yr follow-up. Statistical analysis was made to evaluate whether differences in MFIQ, VAS, maximum opening and protrusion, lateral joint tenderness, muscle tenderness, crepitation, and clicking at 1-yr follow-up from baseline were significant. Results were considered statistically significant when P < .05. RESULTS Both open surgery and arthroscopic surgery reduced pain and improved mandibular function. The severity of pain was significantly reduced in both groups (P = .005). In both the open and arthroscopy groups mandibular function improved significantly (P = .005). The clinical examination showed similar good results for the 2 surgical procedures. At 1-yr follow-up a majority of patients from both the open (80% of the patients) and the arthroscopy (70% of the patients) groups fulfilled the criterion of a cutoff point for maximum interincisal opening of equal or more than 35 mm (P = 0.005); all the patients in both groups fulfilled the criterion of the cutoff point for maximum protrusion of more than 5 mm (P = .007). At 1-yr follow-up, clicking was the same as before surgical procedures; no patient in the open group showed crepitation, but crepitation was found in patients in the arthroscopy group. Joint tenderness and pain on lateral palpation as well as muscle tenderness and pain were reduced in all the cases, disappearing in some of them, but the difference was significant only regarding joint tenderness (open surgery, P = .016; arthroscopy, P = .031). CONCLUSIONS Open-surgery high condylectomy and disc repositioning and the arthroscopic procedure of lysis, lavage and capsular stretch are both effective surgical methods to treat symptomatic patients with a diagnosis of chronic closed lock of the TMJ. Because of the minimally invasive character of the arthroscopic procedure, it should be considered as the first choice in the surgical treatment of the TMJ.

Abstract
Surgery of the temporomandibular joint (TMJ) plays a small, but important, role in the management of patients who have temporomandibular disorders (TMDs). There is a spectrum of surgical procedures for the treatment of TMD that ranges from simple arthrocentesis and lavage to more complex open joint surgical procedures. It is important to recognize that surgical treatment rarely is performed alone; generally, it is supported by nonsurgical treatment before and after surgery. Each surgical procedure should have strict criteria for which cases are most appropriate. Recognizing that scientifically proven criteria are lacking, this article discusses the suggested criteria for each procedure, ranging from arthrocentesis to complex open joint surgery. The discussion includes indications, brief descriptions of techniques, outcomes, and complications for each procedure.

Abstract
The literature is unequivocal in its support for surgery in the management of certain disorders of the Temporomandibular joint (TMJ). Unfortunately, the literature on TMJ surgery is based more on observation than science since randomised clinical trials comparing surgical treatment of the TMJ with medical treatment and no treatment (i.e., placebo) do not exist. Because the application of scientific principles in clinical studies which involve surgical intervention are ethically unfeasible, the true benefit of surgical intervention for Temporomandibular Disorders (TMD) may never be conclusively established. Waiting for properly designed, placebo controlled, random clinical trials will only impede the progress of surgical experience and frustrate the decision making for both clinicians and patients. Therefore, the current recommendations for surgery must rely on the best available evidence. The aim of this, the second of two papers, is to scrutinize the role of TMJ surgery in light of the controversies that have appeared in the literature in recent years.

Abstract
Despite the controversy surrounding the role of surgery in the management of Temporomandibular Disorders (TMD), studies in peer review journals continue to support the role of surgery as a legitimate means of treating pain and dysfunction in the Temporomandibular Joint (TMJ). To better understand the role of surgery in the management of TMJ disorders, a critical review of the literature will be presented in two parts. Part 1 reviews the evolution of TMJ surgery together with the biological evidence for surgical disease. History teaches us that we are destined to repeat the mistakes of the past if we fail to properly reflect on what has already been achieved and where the failures have occurred. With the help of molecular biology, the future of TMD management may comprise more carefully targeted and less radical treatment modalities.

Abstract
PURPOSE The study was designed to evaluate the outcome of standard arthroscopic lysis and lavage for internal derangement with various levels of severity by comparing the preoperative staging with arthroscopic findings and subsequent success rates. PATIENTS AND METHODS Temporomandibular joint disorder in 23 patients (26 joints) who underwent arthroscopic lysis and lavage was preoperatively classified as Wilkes stages II-V based on the clinical and radiologic (magnetic resonance imaging) findings. Recorded arthroscopic findings were scored and compared with the stages. The patients were examined both preoperatively and after a mean follow-up of 22.7 months, using objective and subjective criteria. RESULTS The arthroscopic findings showed a correlation between increasing scores and advancing stage. Postoperatively, the patients could be clearly classified into 2 groups with either satisfactory or poor clinical outcome. Overall success rate was 78.3% (18/23). The success rates were slightly lower for patients with advanced stages than for those of stages II and III. Patients totally unresponsive to the treatment were found in all stages. CONCLUSION Arthroscopic lysis and lavage is a preferred treatment for different stages of internal derangement. Preoperative staging and corresponding characteristics of the arthroscopic findings do not seem to correlate with the prognosis of the treatment outcome.

Abstract
INTRODUCTION The articular disk has a central role in the pathology of internal derangement of the Temporomandibular Joint (TMJ). What is less clear is the role of osteoarthrosis in the development of internal derangement. The aim of this study is to determine the prevalence of osteoarthrosis in cases of advanced and recalcitrant TMJ internal derangement that were treated by diskectomy. MATERIALS AND METHODS This study involved 22 joints in 18 patients who underwent surgery for the treatment of advanced and recalcitrant internal derangement of the TMJ. All patients included in the study failed to respond to at least 6 months of pre-operative conservative treatment and the clinical diagnoses of advanced TMJ internal derangement were confirmed on pre-operative MRI's. Tissue specimens were obtained from all 22 joints for histopathology. The specimens included articular disks that were excised from all 22 joints which were found to have severely displaced and deformed disks that were judged to be irreparable at the time of surgery. Also included were eight tissue samples from the mandibular condyles that were judged to be diseased on pre-operative tomograms and at the time of surgery. All samples were prepared in serial sections in the standard way and examined under light microscopy by two experienced Oral Pathologists. RESULTS There were 22 specimens of articular disk examined together with 8 specimens from the mandibular condyle. All 22 joints (100%) showed histological evidence of disk pathology and eight of the 22 joints (34.4%) were found to have condylar pathology. The most common disk pathology was hyalinization indicative of disk degeneration (12/22). The most common condylar pathology found was articular surface degeneration indicative of osteoarthrosis (8/22). CONCLUSION The clinical and radiological diagnoses of advanced TMJ internal derangement correlated with histological findings of degeneration and inflammation of the articular disk in all 22 specimens. The 8 specimens obtained from the condylar head showed histological features consistent with osteoarthrosis. This study showed that osteoarthrosis and internal derangement were found to co-exist in the same joint in about one-third of cases. The fact that osteoarthrosis was not found in all cases suggests that perhaps the widely held view that subclinical osteoarthrosis may lead to pathologic tissue responses in the form of internal derangement will need to be re-examined.

Abstract
The individual single images obtained to document TMJ arthroscopy are often difficult to interpret. The aim of this paper is to make available a new computer-aided image process system to reformat the panoramic arthroscopic images of the temporomandibular joint (TMJ). Arthroscopic images were input directly into a computer and memorized into a magneto optical disk. Using Photoshop 5.0 (Adobe Systems, Inc., Mountain View, CA) software for Windows 98 (Microsoft Corp., King County, WA) the images were edited and adjusted to compound sagittal and/or coronal panoramic images of normal articular surfaces as well as pathology of TMJ disorders. Normal TMJ sagittal and coronal two-dimensional composite panoramic arthroscopic images were achieved. The panoramic images of some intracapsular disorders (including disk displacement, osteoarthrosis, adhesion, and disk perforation) were also obtained. The computerized arthroscopic panoramic images are a new technique that may aid in the understanding of TMJ anatomy and TMJ disorders.
