Functional Jaw Reconstruction after Ablative Surgery: The New Trend

Abstract

 

Keywords: computer-assisted surgery, virtual surgical planning, 3D printing, patient-specific implants, jaw reconstruction, free flap

 

 

Tumors that require mandibular resection will create defects of the mandible. The aim of jaw reconstruction is to restore facial appearance and functions, including chewing, swallowing, speech, airway, etc. With the use of computer-assisted surgery and 3D printing technology, mandibular reconstruction can achieve high accuracy, repeatability, and predictability, which will benefit dental rehabilitation. Our experience shows that computer-assisted mandibular reconstruction leads to satisfactory clinical outcomes in both facial appearance and functional aspects. 

 

The lecture will discuss and compare different approaches in functional jaw reconstruction, including primary vs. secondary reconstruction, primary vs. secondary dental implantation, and the “jaw-in-a-day” approach.  The results proved that virtual surgical planning and patient-specific surgical plates facilitate functional jaw reconstruction. 

Computer-aided Cranioorbital Surgery

Cheng-Hsien WU

 

Management of lesions involving the cranioorbital region is challenging. The operation may cross both the cranial cavity and the orbital cavity. Therefore, surgical treatment on this junctional zone is a topic which lies between different specialties, especially the neurosurgeons and ophthalmologists. The complex nature of the neurovascular structures challenges the surgeon’s knowledge to anatomy, experience, and the perception toward surgical outcome. Meanwhile, it also possesses a high risk for both neural and ophthalmic complications. The goal of these surgeries is not only a maximum resection to relieves the associated symptoms, but the reconstruction should also be aim on the restoration of patient’s function and esthetics. As maxillofacial surgeons, our training background provides better understanding on the craniomaxillofacial structures, which is a new avenue to deal with the cranioorbital diseases. With the rapid development of digital technologies and computational algorithm, modeling/navigation techniques profoundly change the surgical practice in craniomaxillofacial surgeries. Volume rendering from different image sources allows the surgeon to analyze the patient in three-dimensional format and to manipulate deformed or missing facial structures by computational algorism such as mirroring, segmentation, or insertion of unaltered or ideal skeletal constructs. The execution of the virtual planning is then accomplished by using stereolithographic models (SLMs), implants, cutting guides, or through image-guided surgery in the form of intraoperative navigation. Precision and reduced operation time are the main benefits from using computer assisted approaches. When combing endoscope and remote surgical approaches, tumor resection and customized reconstruction could be done with minimal visible scar. In this presentation, I will share the Taipei Veterans General Hospital experience of practicing computer-assisted approach on cranioorbital diseases.

Maxillofacial Surgery in Veterinary Medicine

Traumatic abnormalities and neoplasia are common maxillofacial surgical diseases in dogs and cats. Maxillofacial traumatic abnormalities may result from animal bites, vehicular accidents, blunt force traumas, or falls from height. However, they are infrequently encountered during bone reconstruction in clinical practice in Taiwan because of the life-threatening consequences for companion animals due to their relatively small size, sustaining high-velocity impact injuries. Feline high-rise syndrome may result in maxillofacial and temporomandibular joint injuries, and closed reduction or condylectomy could be performed with satisfactory results. Neoplasia is responsible for the majority of maxillofacial surgeries performed in our hospital. Partial maxillectomy and partial/total mandibulectomy are common surgical procedures applied for treatments. Although postoperative complications may include malocclusion or tongue protrusion, cosmesis and function are usually good for the dogs. Some cats may refuse to eat after the procedure, requiring tube feeding. 

Advancement in maxillofacial surgery in veterinary medicine remains ongoing, and the challenges may differ from those observed in human medicine.

 

Suppression of Osteoclastogenesis by Dermokine via Suppressing RANKL-Induced Signaling Pathways in Periodontitis

Introduction:

In alveolar bone, bone resorption and bone formation are balanced by the regulation of various hormones and cytokines, so that new bone replaces old bone and stabilizes the volume of alveolar bone. This process is called bone remodeling.

Dermokine is a predominantly secreted glycoprotein localized in epithelial tissues and is differentially regulated in inflammatory conditions. The association of dermokine in various organs, such as pancreatic cancer and colorectal cancer, has been reported, ranging from an increase in inflammatory skin disease to inhibition of skin wound healing. However, there are few studies on dermokine in periodontitis.

The purpose of this study was to investigate the relationship between periodontitis and dermokine

Materials and Methods:

The expression of dermokine in the public database is confirmed in periodontitis patients. The expression of dermokine in human gingival fibroblasts was confirmed by treatment with LPS. The expression of dermokine was confirmed by inducing gingivitis in 6-week-old male mice. The cytotoxicity of dermokine was confirmed in Mouse Bone Marrow-Derived Macrophages. After dermokine treatment, check the formation of osteoclasts. After dermokine treatment, the expression of five Transcription Factors (TRAP, cathepsin K, DC-STAMP, NFATc1, c-Fos, ERK, JNK, p38) is confirmed.

Results: 

Dermkine acts as a negative regulator of osteoclast differentiation in the periodontitis environment and mediates the MAPK pathway.
