Abstract 39-year-old male seen at ENT clinic with inverted papilloma polyp of nasal sinus. CT showed multi-sinus mucosal thickening. The surgical options discussed were modified Lothrops endoscopic sinus surgery or an open approach of frontal sinuses with osteoplastic flap and septorhinoplasty. A model 3D skull was created by Axial 3D using stereolithography 3D printing technology with photopolymer resin. The skull was made in 1:1 scale with tolerance of 0.2mm. The tumour was printed in a contrasting colour, which allowed clear visualisation and appreciation of tumour boarders and relations to surrounding structures. The patient underwent FESS with modified Lothrops approach, achieving good clearance of polyp. The operation resulted in relief the patient’s symptoms. Discussion The use of a 3D model allowed for visualisation of tumour size and relation to surrounding anatomy, particularly the absence of dural involvement within the fontal sinus. It assisted in surgical planning. The use of the 3D skull was beneficial for patient as it allowed less invasive surgery and therefore shorter recovery time. It was also beneficial for the hospital organisation as it lowered resource requirements of theatre time, hospital bed days and staff resources. One limitation of the 3D printed skull was that the fine lamellae ethmoid air cells were not shown due to the manufacturing process. Conclusions The use of 3D printing is becoming increasingly popular as a surgical aid. We found the use of the 3D skull to be useful in individualised surgical planning for endoscopic sinus surgery.

AbstractThe endovascular technique has led to a revolution in the care of patients with vascular disease; however, acquiring and maintaining proficiency over a broad spectrum of procedures is challenging. Three-dimensional (3D) printing technology allows the production of models that can be used for endovascular training. This article aims to explain the process and technologies available to produce vascular models for endovascular training, using 3D printing technology. The data are based on the group experience and a review of the literature. Different 3D printing methods are compared, describing their advantages, disadvantages and potential roles in surgical training. The process of 3D printing a vascular model based on an imaging examination consists of the following steps: image acquisition, image post-processing, 3D printing and printed model post-processing. The entire process can take a week. Prospective studies have shown that 3D printing can improve surgical planning, especially in complex endovascular procedures, and allows the production of efficient simulators for endovascular training, improving residents’ surgical performance and self-confidence.

Chevron Osteotomy

Abstract Background Cubitus varus deformity (CVD), a common complication after a supracondylar fracture of the distal humerus, is usually treated with corrective osteotomy. However, due to the complex anatomy of the distal humerus, conventional osteotomy techniques are sometimes unreliable and can result in an inaccurate correction, residual deformity, and lateral condyle prominence. Recently, medial three-dimensional (3D) printing technology has demonstrated potential benefits for the treatment of CVD by improving the accuracy of the osteotomy through the use of an osteotomy guide with or without a patient-mated plate. This study aimed to present an interesting CVD case involving a patient who was treated with corrective biplanar Chevron osteotomy using an innovative customized osteotomy guide and a newly designed patient-matched monoblock crosslink plate created with 3D printing technology. Methods A computer simulation was processed using images from computerized tomography(CT) scans of both upper extremities. The biplanar Chevron osteotomy was designed to create identical anatomy between the mirror image of the contralateral distal humerus and the osteotomized distal humerus. Next, the customized osteotomy guide and patient-matched monoblock crosslink plate were designed and printed. A simulation osteotomy for the real-sized bone model was created. Results The operation was performed using the posterior paratricipital approach and the k-wire position from the customized osteotomy guide as a predrilled hole for screw fixation to achieve immediate control of the reduction after osteotomy. Our method helped successfully treat the CVD in the case study patient and significantly improved her radiographic and clinical outcomes with a satisfactory result. Conclusion This study showed that the treatment of CVD using 3D printing technology to create an innovative customized osteotomy guide and a patient-matched monoblock crosslink plate can help accurately assess and control the CVD correction. To the best of our knowledge, this case report introduces a new insight for the clinical application of 3D printing technology in the treatment of CVD.

We thank Shixiong Wei et al for their interest in our technical paper on Robotic Septal myectomy for HOCM and their letter to the editor. Their technique of using the Computed Tomography Angiography (CTA) along with 3D Printing technology for the better delineation of the anatomy of HOCM has been an evolving way to approach the problem. As they have mentioned in their letter, we used cardiac magnetic resonance imaging (MRI) predominantly for all our patients who undergo septal myectomy. Using 3D printing technology augmenting CTA or MRI can certainly augment the surgical planning in complex patients. In their case report, Wei et al have shaved off most of the subvalvular tissue along with the mitral valve. Removal of the entire mitral valve definitely would have enhanced the exposure to the mid-ventricular cavity and the apex for their thoracoscopic approach. It will be interesting to know whether they tried to repair the valve before replacement. Our technique of Robotic mitral valve repair, septal myectomy, and particularly papillary muscle re-orientation tries to preserve the sub-valvular apparatus even after completely relieving the mid-cavitary obstruction and this may provide better ventricular re-modeling. We congratulate them on providing a successful surgical option to this complex subset of patients using novel evolving technology and meticulous surgical planning.
