“…fusion of 2D-into 3D-images using computed tomography (CT) slides), and rapid prototyping (building a physical model using computer aided design (CAD) software, e.g. 3D printing) facilitate the effective and accurate construction of patient-specific anatomical models, surgical guides and implants [7][8][9][10], thus opening new avenues for pre-operative rehearsals.…”

Technical difficulty of an operation is associated with patient and disease characteristics, indicating the necessity for surgeons to exercise patient-specific preparation. Such methods have been shown to be effective in the simulation suite, however, application in a real clinical environment has been sporadic. This systematic review attempts to answer if patient-specific preparation in challenging surgical procedures is feasible. A systematic review of OvidMedline, Embase and all Evidence Based Medicine review databases, was conducted in search of studies who described surgical rehearsals in all specialties. Following the application of defined inclusion and exclusion criteria relevant data were extracted and summarised. Descriptive synthesis was performed for all included studies and meta-analysis of data was applied when possible. Of fourty-nine studies included, thirty-seven were case-series, ten were non-randomised comparative trials and two randomised controlled trials. Accuracy of applied methods ranged from 66.7 to 100% and a good outcome was seen in 60-100% of operations. Meta-analysis of studies comparing rehearsals to real procedures (same patients) showed that simulated procedures were significantly faster than real ones (SMD ¼ À1.56 [À2.19, À0.93] p < 0.00001) but were similar in other outcomes (fluoroscopy time: SMD ¼ À0.1 [À0.63, 0.42] p ¼ 0.7, fluoroscopy volume: SMD ¼ À0.43[À0.97, 0.11], p ¼ 0.12). Meta-analysis of studies comparing pre-operative rehearsals to standard treatment (two distinct groups of patients), demonstrated that real procedures were performed quicker if pre-operative rehearsal took place (SMD ¼ À0.47 [À0.79, À0.16], P ¼ 0.003) but the immediate clinical outcome was similar for practiced and not practiced operations (SMD ¼0.03[À0.23, 0.29], p ¼ 0.82). Current evidence suggests that patient-specific pre-operative preparation is feasible and safe and decreases operational time.

“…The screw holes used to hold the cutting guides in place corresponded with the holes on the subsequent prosthesis which provided further confirmation that the joint fitted perfectly. A similar procedure has been reported by Haq et al ,10 which uses cutting guides to perform the planned resection of bone. They used the ‘TMJ medical’ system with good results in a case series of five patients.…”

“…The first procedure removes the ankylotic mass and a spacer is inserted, followed by postoperative CT scanning. This allows a custom-made prosthesis to be constructed from the CT images, which is fitted during the second procedure 10. One-stage procedures either need to use stock prostheses which are not made exactly to the patients anatomy or pose the problem of contouring the glenoid fossa and mandibular ramus so that the custom-made components fit accurately 11.…”

Single-stage temporomandibular joint arthroplasty in a patient with complete bony ankylosis and previous extradural haematoma

SUMMARYWe present a case of a man aged 20 years who was referred with the inability to open his mouth as a consequence of severe ankylosis of his temporomandibular joint. He had previously undergone an attempt to release the ankylosis at the referring institution; however, this was complicated by an extradural haematoma as a result of iatrogenic injury. We describe a one-stage procedure which provided safe excision of the ankylotic mass along with immediate total joint replacement with a custom implant. We advocate the use of preoperative vascular imaging along with the use of custom-made cutting guides to minimise vascular injury. BACKGROUND

“…Digital templates have proved to be accurate and effective tools for many procedures performed internationally, as well as at our center. [16][17][18] However, the application of digital templates in total alloplastic joint replacement surgery has rarely been reported, except for the reports on TMJ ankylosis cases by Chandran et al 20 and Haq et al, 21 in which the fossa was filled with plenty of heterotopic bone, which could support the fossa prosthesis in a stable manner. For the condylar osteoarthritis and osteochondroma patients, however, the fossae were concave; thus it was very difficult to place flat prostheses in these fossae, although bone trimming was performed.…”
