Surgical planning assistance in keyhole and percutaneous surgery: A systematic review

Study Design: Retrospective case series; systematic review. Objective: It is unknown whether the use of virtual surgical planning (VSP) to facilitate same-admission microsurgical reconstruction of the mandible following acute maxillofacial ballistic trauma (MBT) is sufficient to achieve definitive reconstruction and functional occlusion. Methods: A single-center retrospective analysis was conducted for patients who underwent microsurgical reconstruction of the mandible using VSP after acute MBT. The PubMed/MEDLINE, Embase, ScienceDirect, and Scopus databases were systematically reviewed using blinded screening. Studies were evaluated via thematic analysis. Results: Five patients were treated by same-admission and microsurgical reconstruction of the mandible using VSP. We observed an average of 16.4 ± 9.1 days between initial presentation and reconstruction, an average length of stay of 51.6 ± 17.9 days, 6.2 ± 2.8 operations, and 1.6 ± 0.9 free flaps per patient. Four types and 8 total flaps were employed, most commonly the anterior lateral thigh flap (37.5%). Care yielded complete flap survival. Each patient experienced at least 1 minor complication. All patients achieved centric occlusion, oral nutrition, and an approximation of their baseline facial aesthetic. Follow up was 191.0 ± 183.9 weeks. Systematic review produced 8 articles that adhered to inclusion criteria. Consensus themes in the literature were found for clinical goal and function of VSP when practicing MBT reconstruction, yet disagreement was found surrounding optimal treatment timeline. Conclusions: Same-admission microsurgical reconstruction after MBT is safe and effective to re-establish mandibular form and function. VSP did not delay reconstruction, given the need for preparation prior to definitive reconstruction.

Dimensional Printing

Background: In cases with solid tumors, preoperative radiological investigations provide valuable information on the anatomy of the tumor and the adjoining structures, thus helping in operative planning. However, due to a two-dimensional view in these investigations, a detailed spatial relationship is difficult to decipher. In contrast, three-dimensional (3D) printing technology provides a precise topographic view to perform safe surgical resections of these tumors. This systematic review aimed to summarize and analyze current evidence on the utility of 3D printing in pediatric extra-cranial solid tumors. Methods: The present study was registered on PROSPERO—international prospective register of systematic reviews (registration number: CRD42020206022). PubMed, Embase, SCOPUS, and Google Scholar databases were explored with appropriate search criteria to select the relevant studies. Data were extracted to study the bibliographic information of each article, the number of patients in each study, age of the patient(s), type of tumor, organ of involvement, application of 3D printing (surgical planning, training, and/or parental education). The details of 3D printing, such as type of imaging used, software details, printing technique, printing material, and cost were also synthesized. Results: Eight studies were finally included in the systematic review. Three-dimensional printing technology was used in thirty children with Wilms tumor (n = 13), neuroblastoma (n = 7), hepatic tumors (n = 8), retroperitoneal tumor (n = 1), and synovial sarcoma (n = 1). Among the included studies, the technology was utilized for preoperative surgical planning (five studies), improved understanding of the surgical anatomy of solid organs (two studies), and improving the parental understanding of the tumor and its management (one study). Computed tomography and magnetic resonance imaging were either performed alone or in combination for radiological evaluation in these children. Different types of printers and printing materials were used in the included studies. The cost of the 3D printed models and time involved (range 10 h to 4–5 days) were reported by two studies each. Conclusions: 3D printed models can be of great assistance to pediatric surgeons in understanding the spatial relationships of tumors with the adjacent anatomic structures. They also facilitate the understanding of families, improving doctor–patient communication.

Blood Samples

Despite therapeutic advances, colorectal cancer (CRC) is still one of the deadliest cancers, partly due to local recurrence and metastatic disease. Tumour cells that spread by gaining access to peripheral blood are called circulating tumour cells (CTCs). These may be present before there are any clinical signs, but can be detected within blood samples. CTCs from patients with CRC may be isolated in a laboratory for characterization and multiple analyses. In this review, we focus on the prognostic potential of CTCs detection, by evaluating the reported progress and applications of such analyses. Our search found 77 relevant studies that reported CTC detection in CRC. Both cell count and features were reported as promising prognosis biomarkers. Since CTCs are rare and can lose their differentiation, new tools are being developed to improve detection. CTCs may have potential as prognostic biomarkers for CRC in terms of survival prediction, anticipating chemotherapy resistance, and surgical planning. CTCs are not yet used in clinical practice, and further investigations are required in order to better frame their practical value.

Crown Lengthening

The surgical procedure for the clinical crown lengthening, aims for an aesthetic or functional form to compensate for the reabsorption of the alveolar bone tissue caused by the invasion of the biological space. The conditions that must be taken into account during surgical planning are related to an excessive gingival exposure, altered passive eruption and lack of height of the dental element for restorative purposes. The objective of this systematic review was to evaluate in the scientific literature the minimally invasive surgical techniques used to clinical crown lengthening. A systematic review of the literature was performed using the databases, Science Direct, Embase, Cochrane Collaboration Library, and PubMed/MEDLINE. The search strategy provided a total of 157 studies. After selection, five articles met all the inclusion criteria and were included in this systematic review. Studies have shown that conventional surgical techniques for clinical crown lengthening are presented as an effective approach that promotes good aesthetic and functional results. However, they have some limitations. After evaluating the minimally invasive surgical techniques included in this systematic review, it was possible to infer that they presented satisfactory results in the soft and hard tissue contouring, with no complications and dissatisfaction being observed by the patients.

Background. The wedge opened during high tibial osteotomy defines the alignment correction in different body planes and alters soft tissue insertions. Although multiple complications of the surgery can be correlated to this, there is still a lack of consensus on the occurrence of those complications and their cause. The current study is aimed at clarifying this problem using a combined medical and biomechanical perspective. Methods. We conducted a systematic review of the literature on selective complications of the surgery correlated with the angles of the opened wedge. Search topics covered tibial slope alteration, patellar height alteration, medial collateral ligament release, and model-based biomechanical simulations related to surgical planning or complications. Findings. The selection process with the defined inclusion/exclusion criteria led to the collection of qualitative and quantitative data from 38 articles. Medial collateral ligament tightness can be a valid complication of this surgery; however, further information about its preoperative condition seems required for better interpreting the results. The posterior tibial slope significantly increases, and the patellar height (using the Blackburne-Peel ratio) significantly decreases in the majority of the selected studies. Model-based biomechanical studies targeting surgical planning are mostly focused on the lower-limb alignment principles and tibiofemoral contact balancing rather than surgical complications. Interpretation. Increased posterior tibial slope, patellar height decrease, and medial collateral ligament tightness can occur due to alterations in different body planes and in soft tissue insertions after wedge opening. This study clarified that information about preoperative alignment in all body planes and soft-tissue conditions should be considered in order to avoid and anticipate these complications and to improve per surgery wedge adaptation. The findings and perspective of this review can contribute to improving the design of future clinical and biomechanical studies.
