Application of 3D-Printed Model in the Cervical Spine Osteochondroma Surgery: A Case Report

Abstract

A 73-year-old woman having a throat lump sensation and dysphagia for the past several months presented at our otorhinolaryngology outpatient clinic. A physical examination disclosed a protruding subepithelial mass over the right tonsil fossa. The mass was not tender and had no mucosal lesions or signs of active infection. Therefore, we arranged face and neck computed tomography scans, which reported a solitary osseous lesion over the anterior-right aspect of the C1-2 joint. Considering the rarity and unfamiliar anatomy of this disease, we built a 3D-printed model to assist with the surgical rehearsal of the procedure as well as with a preoperation discussion with the patient and her family. We arranged a combined Otolaryngology-Neurosurgery department approach after discussion with the neurosurgeon and successfully removed the lesion without sacrificing the overlying longus capitis muscle. The pathology examination revealed no evidence of malignancy. The final diagnosis was cervical spine solitary osteochondroma. The patient had a complete recovery of both oral cavity and normal swallowing function. No tumor recurred during the 3-year follow-up. On the basis of this case, in-house 3D-printing technology can offer a rapid, reliable model for an interdisciplinary team to use to enhance personalized presurgical planning, thus providing better patient engagement during hospitalization.

3D-printed Titanium Prosthetic Reconstruction of Unilateral Bone Deficiency After Surgical Resection of Tumor Lesions in the Upper Cervical Spine

“…10 In 2021, Liao at el reported the employment of a 3D-printed model to assist with the surgical rehearsal of the procedure in one patient with a bone tumor over the anterior-right aspect of the atlantoaxial joint. 26 Here, we first presented 3 cases with the employment of 3D-printed prostheses for reconstructing the unilateral bone deficiency in the upper cervical spine. Customed device with a single arm was designed on the base of our previous clinical follow-up outcomes and existing literature.…”

“…At the same time, Samuel et al described the successful use of custom 3D-printed prostheses for the reconstruction of the anterior vertebral column of C2 in 3 consecutive cases 10 . In 2021, Liao at el reported the employment of a 3D-printed model to assist with the surgical rehearsal of the procedure in one patient with a bone tumor over the anterior-right aspect of the atlantoaxial joint 26 . Here, we first presented 3 cases with the employment of 3D-printed prostheses for reconstructing the unilateral bone deficiency in the upper cervical spine.…”

“…The application of 3D printing in upper cervical spine surgery offers several benefits, including improved preoperative planning, reduced surgical complexity, producing a more anatomically fit prosthesis for irregular bone defect, assisting in accurate placement of prosthesis, and enhanced productivity. 10,25,26 Vivid images of nerves, vessels, and bone architecture in the occipital and cervical joint region provided by the 3D-printed model help us comprehend the anatomic relationships in patients suffering atlantoaxial lesions. 10,25 The screw length and angulation can be predetermined during the design of 3D-printed prosthesis, thereby minimizing the risk of neurovascular complication and maximizing screw-bone interface.…”

Virtual Scoliosis Surgery Using a 3D-Printed Model Based on Biplanar Radiographs

“…The global 3D-printing market is growing in the field of orthopedics and spine surgery [ 1 , 2 , 3 ]. Companies and surgeons are increasingly adopting 3D printing for custom or patient-specific implants [ 4 , 5 , 6 , 7 , 8 ]. 3D printing is also becoming ever more popular for surgical planning [ 3 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ] as well as for educational purposes.…”
