“…In institutions with micro-vascular expertise, vascularized composite free flaps can replace bone and soft tissue with good success. 31 Most commonly used are the fibular free flaps held together by mini-plates. A more straightforward approach of mandibular reconstruction though is through the use of larger prosthetic metal plates.…”

Presented is a case of a 62-year-old female who underwent segmental resection with iliac bone graft reconstruction for recurrent ameloblastoma. Another recurrence was noted 14 years later, this time with involvement of the osseous graft. A search of recurrences on bone grafts showed limited reports in literature. The authors explore possible reasons for this unusual occurrence and present current treatment recommendations in ameloblastoma management. Key words: ameloblastoma, head and neck surgery, oromandibular reconstruction, recurrence

“…The surgical reconstruction of bony defects in the mandible is a routine procedure performed for the rehabilitation of patients who require the reconstruction of the continuity of the mandible, due to impairment from injury or removal of the tumor [1]. The mandible plays an important role in chewing and swallowing; it is also important for vocalization [2,3,4]. It is a part of the stomatognathic system [2], and also provides the contour of the lower face, significantly affecting the aesthetics of the face [5].…”

We have tested titanium (Ti) plates that are used for bone reconstruction in maxillofacial surgery, in combination with five types of novel long-resorbable biomaterials: (i) PCL0—polycaprolactone without additives, (ii) PCLMWCNT—polycaprolactone with the addition of multiwall carbon nanotubes (MWCNT), (iii) PCLOH—polycaprolactone doped with multiwall carbon nanotubes (MWCNT) containing –OH hydroxyl groups, (iv) PCLCOOH—polycaprolactone with the addition of multiwall carbon nanotubes (MWCNT) containing carboxyl groups, and (v) PCLTI—polycaprolactone with the addition of Ti nanoparticles. The structure and properties of the obtained materials have been examined with the use of Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), and/or X-ray powder diffraction (XRD). Titanium BR plates have been covered with: (i) PCL0 fibers (PCL0BR—connection plates), (ii) PCLMWCNT fibers (PCLMWCNTBR—plates), (iii) PCLOH fibers (PCLOHBR—plates), (iv) PCLCOOH (PCLCOOHBR—plates), (v) PCLTI fiber (PCLTIBR—connection plates). Such modified titanium plates were exposed to X-ray doses corresponding to those applied in head and neck tumor treatment. The potential leaching of toxic materials upon the irradiation of such modified titanium plates, and their effect on normal human dermal fibroblasts (NHDF) have been assessed by MTT assay. The presented results show variable biological responses depending on the modifications to titanium plates.

Aims and Objectives 3d-printed models (bio-models) have become a useful tool in the armamentarium of surgeons for improved surgical planning in the recent past. This study directs at reinforcing the incorporation of these bio-models as a handy tool in treatment planning, resident training, patient education and record maintenance. The aim of this empirical study was to compare the outcome in reconstructive maxillofacial surgery when planned using 3d-printed model and without 3d-printed model (conventional). The objectives were to assess and compare the intraoperative time taken during reconstruction, the immediate post-operative experience (pain, mouth opening and incidence of infection) and the quality of life using University of Washington (UW-QOL) questionnaire during follow up. Methods This retrospective comparative study was conducted in Department of Oral & Maxillofacial Surgery, from March 2018 to March 2020. It included 50 cases consisting variety of pathologic and traumatic maxillofacial defects and they were grouped into with 3d-printed model (Group A) and without 3d-printed model (Group B). The groups were further subclassified based on maxillary (MR) and mandibular reconstruction [vascularized flaps (VFFF), non-vascularised grafts (NVG), reconstruction plate alone (RP)]. We compared intra operative time taken along with immediate post-operative parameters (pain, mouth opening and presence of infection) and patient’s quality of life using UW-QOL questionnaire. These values were taken for comparison and statistical analysis was done by unpaired t-test. Result There was 14.75% (35.26 minutes) mean reduction in operative time (* P = .029) and reduction in mean visual analogue score (VAS) (* P = .003) with statistically significant difference. However, increase in immediate post-operative mouth opening was not found to be statistically significant difference ( P =.471). The comparison of the social and functional domain of UW-QOL showed statistically significant P-value in saliva (*0.004) and mood (*0.002) with regard to NVG. In RP group, pain (*0.026), swallowing (*0.041) and taste (*0.008) was found to be statistically significant. In MR group, only pain (*0.037) showed statistically significant difference. Conclusion Use of 3d-printed model to guide and assist in surgical procedures have provided promising results. Based on this study, we found that there is decreased intraoperative time and post-operative pain score when 3d-printed model were used. The patient’s quality of life was also found to be better in terms of reduction in pain, salivary secretion and mood elevation. With increased success rate, the authors are of the strong opinion that it is time to revisit the surgical protocol used for reconstruction and include 3d-printed model as a primary tool or technology across the board for all patients notwithstanding the comparative cost, as the results offset the financial aspect.
