Although implant production has often been outsourced to external companies, in-house planning and manufacturing has developed in many centres. This note introduces a conceptualized modular mould system to perform any desired craniofacial reconstruction, named 'Cubik', inspired by the famous Rubik's cube. A sophisticated virtual process is described that simulates realistic cranio-orbital resections, and the workflow to create multi-component moulds in order to achieve intraoperatively moulded implants is presented. The description focuses on the appropriate definition of interfaces between the subdivision surfaces of the planned implant, which is the key element to successful design and function of the moulds during surgery and is the peculiarity of the Cubik system. The use of Cubik does not prolong the overall duration of surgery, and it appears to be a very versatile tool, allowing personalized implants with different morphology to be created, which are suitable to cover every potential defect of the skull and the orbital region. This study extends the potential of in-house production, allowing highly accurate implantable craniofacial implants to be fabricated, and in the future this might represent a solution to achieve in-house replacement of other segments of the facial skeleton.

[1]. Even if the authors are to be appreciated for their research on the field of computer-assisted surgery, we would like to bring some topics into debate. First of all, we are grateful for citing our previous paper on the same issue, but more attention should be paid to its contents. The authors cannot state that they did not find reports in the literature validating TMJ replacement accuracy with absolute numbers because our work provided an equally reliable method to quantitatively measure the entity of deviation between planned prostheses position and postoperative results providing an overall accuracy estimation [2]. In our opinion, a criticism can be addressed to the method implemented by the authors because they did not specify how they performed the fusion between the preoperative planning model and postoperative result. This plays a crucial role in determining the precision of measurement and this is especially true in those cases where occlusal changes are planned by repositioning the maxilla and the mandible. For this reason, in our work, we decided to separately align the skull base for the fossa component and the mandible for the ramus component. Neglecting this particular for cases in which the mandible position has changed will introduce a systematic bias on the linear measure of screws inserted for the condylar component. The second topic that we would like to emphasize is the use of intraoperative navigation whose implementation in craniomaxillofacial surgery should be encouraged but in TMJ replacement shows several limitations. This technique bears intrinsically an imprecision of about 1 mm furthermore magnified by the fact that the mandible is not a fixed bone. Even a minimal mistake during prostheses positioning might result in undesirable malocclusion. Therefore, we suggest the use of surgical cutting/ positioning guides to provide extreme precision when performing osteotomies and to facilitate the inset of the prostheses. Although the purpose of the article is to validate a system to measure accuracy, results achieved by the authors have to be taken into account, as they do not appear to be completely satisfactory. In fact, there is substantial difference between the virtual planning and the final outcome. Therefore, we can state that in the analyzed cases TMJ replacement was not accurate and the authors should enquiry the underlying reason. On the contrary, our group showed very good results in terms of accuracy of TMJ replacement [2]. Our belief is that accuracy is the result of a cascade of events planned and realized with maximum attention: (1) Ct scan with appropriate protocol for 3D reconstruction; (2) virtual planning; (3) design of cutting/positioning guides useful during surgery; (4) appropriate design of implants; (5) quality control of 3D printed manufacts; (6) precision surgery. In this regard, we have developed a cutting/positioning guide made of titanium to ensure a precise fitting with the underlying bone which allows for precise bone cutting and univocal prostheses insetting using predrilled holes and an * Massimo Robiony massimo.robiony@uniud.it

In many cases, endstage TMJ disease and dentofacial skeletal deformities coexist. The optimal treatment for such conditions is total alloplastic joint replacement and orthognathic surgery. Such procedures have historically been conducted in two separate stages. Furthermore, while technological improvements resulting from the widespread adoption of virtual reality initially led to significant improvements in the field of orthognathic planning, the adoption of virtual design techniques to optimize TMJ reconstruction was a later achievement. Therefore, planning for TMJ replacement and orthognathic surgery did not develop in parallel, leading to various combinations of planning for orthognathic surgery and TMJ replacement with the aim of performing both procedures simultaneously in one stage. Nowadays, improvements in virtual planning and threedimensional printing have allowed these procedures to be conducted in the same surgical step based on fully digital planning and entirely customized surgery. This paper introduces a fully digital protocol for the treatment of end-stage TMJ disease and associated acquired dentofacial deformities, in which all surgical steps are customized and the whole surgery is performed in succession using automated procedures, thanks to the combined use of virtual surgical planning, surgical guides, custom-designed TMJ prostheses, and patient-fitted osteosynthesis devices.

Oncocytic tumors rarely affect the major salivary glands, accounting less than 1% of all salivary gland tumours. Multifocal adenomatous oncocytic hyperplasia in the salivary glands is an extremely rare condition. The differential diagnosis of the clear cell variant includes many malignant salivary gland tumors. We report a new case of multifocal adenomatous oncocytic hyperplasia of the parotid gland in a 64-year-old man. The differential histopathogenesis, diagnosis, and treatment of this rare entity are discussed.

This article assesses the feasibility of reducing isolated zygomatic arch fractures using the intraoral lateral coronoid approach. The procedure is cost-effective and timesaving, as it can be performed under local anesthesia in an emergency department or similar clinical setting and does not need postoperative hospitalization if no other comorbidities are present.

Nevertheless, few studies have investigated the maxillary and mandibular effects after SARPE on the sagittal and vertical planes, with dissimilar results and small samples of patients.The aim of the current study was to evaluate the sagittal and vertical effects after SARPE. Twenty-one consecutive adult patients (7 males, 14 females; mean age, 25.6 ± 6.3 years) who required SARPE were included in this study. All patients were subjected to subtotal LeFort I osteotomy with pterygomaxillary disjunction. Lateral cephalometric radiographs were taken during the preoperative assessment (T0) and 6 months after the end of the expansion (T1). Cephalometric measurements were realized at T0 and T1 for all the patients. Independent-sample t test and analysis of variance were used. Statistically significant changes were observed only in upper incisor^NA (P = 0.04). No skeletal sagittal or vertical variation was found after SARPE. Class II, anterior open bite and/or a steep mandibular plane angle cannot be considered an outright contraindication to its use. Upper incisor palatal inclination could result after SARPE.

The device used is unique in that the cutting action occurs when the tool is used on mineralized tissues and stops on soft tissues. This work describes the use of piezosurgery for hyoid bone resection in thyroglossal duct cyst surgery, briefly reviews the literature on the surgical technique, and reports our experience with 12 cases.

Nineteen patients were studied and underwent surgery using the presented workflow, in both open and endoscopic procedures. Three main scenarios were standardized for the application of computer-guided surgery: single masses of the superior-lateral compartment, single masses of the inferior-medial compartment, and multifocal masses. An operative protocol was devised, and the accuracy of the osteotomies was analysed. All patients were managed successfully by applying the same protocol. No intraoperative complications were reported. The accuracy of the osteotomies was evaluated as a surrogate endpoint for the overall precision of surgery, showing average discrepancies of <1 mm for lateral marginotomies and <0.5 mm for endoscopic osteotomies. This study outlines an operative workflow for the implementation of virtual models to excise orbital masses, enhancing in-depth preoperative understanding of the anatomical relationships within the orbital space and increasing precision in both open and endoscopic approaches.

The authors review 11 TMJ custom-made prostheses made of both mandibular and fossa components. Surgeries were virtually planned and patient-specific devices were designed together with surgical cutting and positional guides. Threedimensional models for both preoperative planning and postoperative computed tomography scans were generated and overlapped in order to evaluate differences in measurements. Correlation between virtual preoperative and real postoperative prosthesis positioning was described by Lin's coefficient. Results of statistical analysis showed an almost perfect concordance. Wilcoxon's matched-pairs test showed no statistically significant deviation between preoperative virtual surgical planning and postoperative results. Colour map analysis confirmed the correspondence between virtually planned positioning of the devices and postoperative results. All the prostheses were placed with great accuracy. In conclusion, virtual surgical planning, surgical guides and patient-specific devices provide accuracy and precision in surgery for custom-made TMJ replacement.

Eighty implant sites were prepared in custom-made solid rigid polyurethane blocks with two different low cancellous bone densities (5 or 15 pounds per cubic foot [PCF]), equally distributed between piezoelectric (Surgysonic Moto, Esacrom, Italy) and conventional drilling techniques. Two short implant systems (Prama and Syra, Sweden & Martina) were tested by inserting 40 fixtures of each system (both 6.0 mm length and 5.0 mm diameter), divided in the four subgroups (drills/5 PCF density; drills/15 PCF density; piezo/5 PCF density; piezo/15 PCF density). Insertion torque (Ncm), implant stability quotient values, removal torque (Ncm), and surgical time were recorded. Data were analyzed by 3-way ANOVA and...

Lifting of the sinus membrane can be difficult due to the presence of bleeding, requiring the alternate use of curved elevators and the aspirator. This technical note presents a new surgical device, a suction dissector specifically designed for sinus membrane elevation. The suction dissector has a curvature similar to that of the curved dissector commonly used for lifting of the sinus membrane and contains an internal channel that allows the aspiration of liquid.
