Dermoid cyst of the parotid gland is a lesion composed of benign tissues of ectodermal and mesodermal origin. Although a dermoid cyst can be encountered across nearly all sites of the body, its location in the head and neck area is quite uncommon and even more unusual inside the parotid gland. We present a case of a patient with gradually enlarging tumour in her right parotid gland who underwent surgical removal of the tumour histologically corresponding to a dermoid cyst.

Although condylar dislocation is not uncommon, terminology, diagnostics, and treatment concepts vary considerably worldwide. This study aims to present a consensus recommendation based on systematically reviewed literature and approved by the European Society of TMJ Surgeons (ESTMJS). Based on the template of the evidence-based German guideline (register # 007-063) the ESTMJS members voted on 30 draft recommendations regarding terminology, diagnostics, and treatment initially via a blinded modified Delphi procedure. After unblinding, a discussion and voting followed, using a structured consensus process in 2019. An independent moderator documented and evaluated voting results and alterations from the original draft. Although the results of the preliminary voting were very heterogenous and differed significantly from the German S3 guideline (p < 0.0005), a strong consensus was achieved in the final voting on terminology, diagnostics, and treatment. In this voting, multiple alterations, including adding and discarding recommendations, led to 24 final recommendations on assessment and management of TMJ dislocation. To our knowledge, the ESTMJS condylar dislocation recommendations are the first both evidence and consensus-based international recommendations in the field of TMJ surgery. We recommend they form the basis for clinical practice guidelines for the management of dislocations of the mandibular condyle.

AIM: Mandibular condylar fractures account for 25 to 52 % of all mandibular fractures. Though current literature favors open reduction and internal fixation (ORIF) of condylar‐base and low condylar‐neck fractures, extraoral approaches are usually considered to be complicated by the risk of facial nerve injury and other possible complications. This study was undertaken to demonstrate that the periangular transmasseteric infraparotid surgical approach (TMIP) to condylar‐base and low condylar‐neck fractures provides excellent access to the bony fragments with minimal risk of complications such as facial nerve and parotid gland injury. PATIENTS: In the period from January 2010 to December 2018, 81patients (96 fractures) with condylar‐base and low condylar‐neck fractures underwent ORIF via periangular transmasseteric infraparotid surgical approach. RESULTS: The results of this retrospective study showed minimal postoperative complications. The periangular transmasseteric infraparotid surgical approach allowed precise anatomic repositioning and fixation of the bony fragments in almost all cases except for two juvenile cases with noticeable scars and one case with plate fracture. There were no transient or permanent facial nerve palsies, parotid gland or salivary fistulae complications during a 12‐month follow‐up period. CONCLUSION: The periangular infraparotid transmasseteric approach to ORIF of condylar‐base and low condylar‐neck fractures is an effective and safe approach allowing accurate anatomic reposition and fixation of the fragments with minimum surgical complications (Tab. 1, Fig. 12, Ref. 21).

The authors evaluated effects of physiotherapy in patients experiencing Wilkes III temporomandibular joint (TMJ) derangement with clinically limited joint mobility, but no pain. The group consisted of 31 patients with unilateral temporomandibular joint involvement, 3 men and 28 women (average age was 30.93, ranging from age 12 to 61). None of the patients in the group had experienced any previous TMJ therapy. The patients underwent conservative therapy in the form of home exercise (mobilisation and isometric exercises) as the first step in treatment. The authors evaluated the improvement in jaw movement (maximal interincisal opening - MIO) and the patients' subjective assessments of their condition. Disc position before and after two months of exercise was also evaluated using ultrasound examination. The average MIO value in patients before starting the exercises was 33.5 mm, and after two months of exercises, 42.4 mm. Subjective assessment by patients: 26 patients (83%) described their condition as completely satisfactory, not requiring further therapy. Of these patients, ultrasound examination showed 10 patients with complete disc reduction, 9 patients with a change in disc displacement with reduction, and 7 patients with a continuing (unchanged) state of disc displacement. Results of our study show the effect of conservative therapy in patients with painless TMJ due to disc displacement (WIII). Effect of home exercises which were easy to perform, simple and acceptable to the patient were demonstrated.
AIM: The purpose of this retrospective study was to perform an evaluation of postoperative positional changes of the condyle and mandibular function after bilateral sagittal split osteotomy (BSSO) with manual proximal segment positioning. PATIENTS: 45 patients were divided into the 2 groups ‒ G1 (advancement ‒ 14 patients) and G2 (setback – 31 patients). Rigid internal fixation screws were utilized in all cases. Inclusion criteria were only BSSO, no TMJ symptoms preoperatively and age 18 or older. RESULTS: The differences between pre- and postoperative condyle position were evaluated using measurements taken from preoperative CT scans and compared to CT scans made a minimum of 6 months postoperatively. The positional changes in both the axial and sagittal planes were measured and compared. The recovery of mandibular function was evaluated by measuring maximal interincisal opening (MIO). The results revealed that condylar positional changes after BSSO in both groups were minimal and not significantly different for all three dimensions measured. The recovery of mandibular function was faster in the group G2 than in the group G1. Mandibular function reached almost preoperative level in 6-12 months postoperatively in both groups. CONCLUSION: The results demonstrated that following BSSO, only insignificant condylar displacement and functional changes occurred within 6 to 12 months postoperatively (Tab. 4, Fig. 2, Ref. 47).

Discectomy with replacement of disc is one possibility for treating disc perforation where conservative, mini-invasive therapy and arthroscopy has had no effect. Allogenic or autologous materials are used to replace the disc. The authors assess the use of a free fat flap (FFF) in 19 patients who in 2015-2016 underwent a unilateral discectomy with disc replacement. In the retrospective 24-month follow-up study a total of 16 patients (84%) were free of difficulties. 24 months after the operation mouth opening was on average 39.3 mm, pain (VAS - visual analog scale (0-10) was assessed on average at 0.3). Crepitus was present after 24 months in 37.5% of patients (6 patients). An assessment of changes in joint structures on cone beam computed tomography (CBCT) for these patients 24 months after the operation showed the progression of flattening of the joint head, in one case unevenness of the joint head. In 3 cases (16%) there was a recurrence of the state within 24 months - in all cases with clinical manifestations of pain and limited mobility, for these patients on the CBCT significant unevennesses of the joint head, subchondral cysts were noted. The authors find discectomy with use of FFF to be an effective method of treatment with a minimum of complications. However, one should take into account the relatively short time of monitoring after the operation (2 years) and limited number of patients in the cohort (19 patients).

PURPOSE: Alloplastic total temporomandibular joint replacement (TMJR) is now considered to be a standard procedure for temporomandibular joint (TMJ) reconstruction. TMJR can improve mandibular mobility, restore the dental occlusion and improve facial aesthetics. The purpose was to assess the presence of intraoperative and post-operative complications, including the presence of post-operative chronic pain. METHODS: This retrospective study evaluated the use of 62 stock TMJR devices implanted in 45 patients who underwent surgery between the years 2006 and 2015 by the same surgeon at the Department of Oral and Maxillofacial Surgery, Stomatology Clinic, General Teaching Hospital (VFN) Charles University, Prague, Czech Republic. RESULTS: Intraoperative and post-operative complications recorded were facial nerve dysfunction (14-22%), open bite/malocclusion (2-3.2%), condylar component dislocation (1-1.6%), infection requiring revision surgery (1-1.6%) and (27-43%) reported chronic pain 24 months after surgery. CONCLUSIONS: As with any surgical procedure, TMJR can have complications. The results of this study demonstrate that the most common post-operative complication was continued pain. Chronic pain after TMJR was more common in patients with a preoperative diagnosis of degenerative joint disease. Also, the incidence of post-operative TMJR pain increased with the duration of symptoms prior to TMJR, leading to a question of the best timing for TMJR.
Sub-condylar fractures of the temporomandibular joint can be treated by an extraoral or intraoral approach. Trans-masseteric antero-parotid approach (TMAP) is an extraoral approach utilising a retromandibular incision. The authors evaluated patients' status and any complications of using TMAP from the years 2013-2017. There were 39 patients (44 fractures). When using TMAP, in 43 fractures the fragments were favourably positioned, in one case the position was compromised. Of the complications, postoperative palsy of the facial nerve was reported 6.8% - in all cases this was only temporary. Late occlusion had an equal number of complications (in 2 cases this was as a result of an infectious complication of the wound, and in 2 cases due to resorption of the proximal fragment). Muscular pain and dysfunction of the temporomandibular joint following trauma were observed consistently in 6.8% of patients. Sialocoele, a non-conforming scar, and infectious complications were observed in 4.5% of patients. TMAP allows rapid surgical performance, with a good view for perfect repositioning and fixation of fragments of sub-condylar fractures of the temporomandibular joint. The complications associated with this approach are, for the most part, temporary, the aesthetic handicap of a scar is considered by patients to be acceptable. Overall, it is possible to evaluate retromandibular TMAP as safe, and the authors recommended it for treatment of sub-condylar fractures of the mandible.

PURPOSE: The objective of the study was to compare results of treatment for chronic recurrent temporomandibular joint dislocation (CRTMD) by autologous blood injection (ABI) using two different methods of administration (combination intra- and peri-articular, and peri-articular alone). MATERIALS AND METHODS: Forty patients diagnosed with CRTMD were randomly divided into two groups of 20 each (A and B). Group A were treated by intra- and peri-articular blood injection, group B were treated by peri-articular injection alone. The follow-up was done at 1, 3, 6, and 12 months. The study assessed presence of dislocations, pain (VAS, 0-10), interincisal mouth opening (IMO), and the presence of sound phenomena. The treatment was considered successful in patients without the persistence of CRTMD symptoms, as well as with a VAS of 0-1. RESULT: After 12 months, a beneficial therapeutic effect in group B was seen in 11 patients, while 16 patients from group A had a therapeutic effect. CONCLUSION: Intra- and peri-articular ABI is more effective than peri-articular blood application alone in the treatment of CRTMD, although the difference was not statistically significant.

PURPOSE: The purpose of this preliminary study was to evaluate intraarticular soft tissues of the temporomandibular joint (TMJ) using intraoperative arthroscopy during open reduction and internal fixation (ORIF) of condylar head fractures (CHF). MATERIALS AND METHODS: 26 patients (29 joints) were diagnosed in period of 5 years (2011-2015) with CHF, 5 patients had concomitant mandibular fracture. Fractures were diagnosed on basis of conventional orthopantomogram (OPG) and computed tomography (CT). RESULTS: Intraoperative arthroscopy revealed hyperemia and hypervascularity in all 29 joints, anterior disc dislocation in 26 joints, cartilage erosion in 21 joints and hemorrhagic clots were present in 10 joints. Major hemarthrosis or tear of the posterior band, as often described in MRI, could not be shown in our patients. Data from the study further the understanding of intraarticular pathology of the TMJ after acute trauma in a group with CHF. CONCLUSION: Intraoperative arthroscopy is useful for direct evaluation and accurate diagnosis of the extent of soft tissue damage to TMJ in CHF. Larger and more long-term studies including comparison to MRI findings should be helpful to refine the treatment and postoperative management of patients after CHF.
