Within the lately printed ‘Mixed software of digital surgical procedure and 3D printing expertise in postoperative reconstruction of head and neck cancers,’ scientists from each the US and China collaborated on a examine to combine digital and 3D printing purposes into postoperative therapy of most cancers.
The authors shared 5 circumstances taken on by the top and neck surgical procedure division the place reconstruction was carried out. Reminding us that each the top and neck are ‘exceptionally complicated,’ that is an space the place organs, vessels, and nerves meet. When tumors develop in such an space, complete resection is the one selection, and generally the surgical procedure should be radical to make sure success.
Whereas each surgical procedure is vital, elimination of a tumor from the top or neck should be well-planned:
“So as to obtain full resection and environment friendly and efficient practical reconstruction, it’s notably vital to develop an affordable preoperative surgical plan and execute that plan within the working room,” said the researchers.
The usage of typical 2D strategies as we speak like ultrasound, CT, or MRI might present the connection between a tumor and surrounding tissue, however additional analysis may be restricted. Because of this, surgeons are challenged to plan for surgical procedures comprehensively. Digital surgical procedure and augmented actuality strategies, nevertheless, together with 3D printing and robotics, make it a lot simpler for surgeons to create a customized method as we speak for therapy, together with every step of a medical process, and post-operative measures.
Digital actuality simulates a digital 3D world, and for surgical procedures—particularly that of a extra complicated space like the top and neck—it might probably really be utilized in a capability that ‘nearly’ replaces a human assistant, helps assess the plan of action for the working room, and acts as a surgical information too.
“Making use of VR expertise to the top and neck could make complicated structural relationships vivid and stereoscopic, making an summary idea intuitive and clear, and convey nice flexibility to the operative subject. We acknowledge the significance of the applying of CAD / CAM and VR expertise in head and neck surgical procedure,” said the researchers.
The researchers outlined the circumstances:
Case One – 53-year-old feminine with mass in her left neck, historical past of recurrent breast most cancers, and a number of surgical procedures associated to that. The biopsy confirmed that the mass in her left neck was malignant fibrous histiocytoma. Surgeons used VR to simulate the surgical procedure, with the usage of a 3D reconstructed mannequin together with:

“Following use of the VR with a number of periods, the affected person underwent prolonged excision of left cervical and thoracic junction tumor with partial left clavicle resection, left subclavian vein restore, and pectoralis main myocutaneous flap restore below normal anesthesia,” said the researchers.
Case Two – 35-year-old feminine offered with three × three cm proper neck mass, found throughout examination for a stroke. Surgeons used VR to create 3D printed fashions and simulate resection.
“After optimizing the preoperative planning, the affected person underwent proper carotid physique tumor resection. VR allowed the surgeon to follow the gradual separation of the tumor on the carotid bifurcation,” said the researchers.
Case Three – 50-year-old feminine with adenoid cystic carcinoma, offered with a 5.zero × four.5 cm mass in her left cheek. A 3D mannequin was created, and simulated reconstruction adopted.
“The affected person then underwent excision of the maxillary tumor, nasal septal resection, bilateral neck dissection, fibula myocutaneous flap restore, and stomach free pores and skin grafting. We use a 3D printed osteotomy plate after CAD design to exactly carry out the suitable osteotomies for resection of the tumor,” said the researchers.
Case 4 – a 51 year-old male was found to have a 2.5 × three.5 cm left gingival squamous cell carcinoma. The left mandible was included, together with a number of ipsilateral lymph nodes. A 3D mannequin was created, together with an osteotomy plate.
“A customized pre-bent plate was designed in response to the pc simulation and the 3D mannequin. We fastened the customized titanium plate at a predetermined place in response to the simulation knowledge and 3D mannequin, and the oral defect was concurrently repaired by the tender tissue part of the flap,” said the researchers.
Case 5 – a 34-year-old girl offered with a 5 cm left submucosal oral cavity lesion, additionally affecting a number of lymph nodes.
“A biopsy of the left mandibular mass confirmed fibrous lesions of bone which inclined to cementite fibroma,” said the researchers.
“A three-dimensional strong mannequin, osteotomy template of the lesion, and the iliac bone had been developed by means of a 3D printer. Pre-bent titanium plates had been ready by the reconstructive mannequin of fast prototyping.”
“We conclude that computer-assisted surgical procedure for customized reconstruction of complicated defects of the top and neck has function in clarifying tumor anatomy relationships, reconstructing complicated osseous and tender tissue defects and defining vascular lesions akin to aneurysms and vascular tumors,” said the researchers, finally.
“This data results in exact surgical therapy of head and neck most cancers sufferers. Nonetheless, its software in head and neck surgical procedure remains to be restricted. Extra systematic scientific outcomes are wanted to verify the general and dependable scientific worth. Nonetheless, we imagine that utilizing computer-aided digital surgical expertise to judge, simulate, formulate, and implement operative plans is a vital development in the way forward for head and neck surgical procedure.”
