    Abstract Background: Ameloblastoma is a locally aggressive, benign tumor presenting in the maxilla and mandible prone to recurrence. Resection greatly limits recurrence; however, reconstruction becomes critical to preserve patients' functionality and esthetics.
    Purpose: The aim of this study was to describe surgical resection and reconstructive approaches in the treatment of ameloblastoma and compare clinical outcomes to conservative methods of treatment.
    Study design, setting, sample: A retrospective case series was completed through analysis of patient records. The study population was composed of patients treated for ameloblastoma at the Royal Brisbane Hospital (Queensland, Australia) in the Oral and Maxillofacial Surgery Unit from January 1, 2008, to December 31, 2020. Patients without histological confirmation of intraosseous ameloblastoma were excluded from the study sample.
    Predictor variable: Not applicable. Main Outcome Variable(s): The primary outcome variable was time to recurrence. Secondary outcome variables included any surgical complications incurred.
    Covariates: The covariate variables collected included age at diagnosis/treatment, gender, ethnicity, location of lesion and site(s) of involvement, tumor extent, alveolar expansion, histopathological growth pattern, and soft tissue involvement.
    Analyses: Descriptive statistics were computed for each study variable.
    Results: A total of 48 cases of histologically confirmed ameloblastoma were identified (41 mandibular, 7 maxillary) involving 50 excisional operations (44 resections, 6 enucleations). Of these cases, 44 were followed up > 12 months, with a mean length of follow-up time of 65.6 months. No recurrence was detected for resected lesions. One enucleated lesion recurred at 25 months. Thirty-seven reconstructive procedures were undertaken, including 32 immediate free flaps. All reconstructive flaps and grafts survived, and no major complications were recorded.
    Conclusion and relevance: Resection of ameloblastoma limits recurrence and should be considered curative. Immediate microvascular free flap reconstruction of maxillary and mandibular defects from resection of ameloblastoma is safe and predictable.

    Abstract Composite free flaps represent the cornerstone for the repair of osseous defects in the head and neck. For many patients, there are often multiple defect-suitable donor sites that may be utilised as part of the reconstructive process. Therefore, to optimise patient outcomes, an evidence-based approach to donor site selection is required to maximise quality of life and long-term functionality. A systematic review of the literature was conducted in accordance with PRISMA guidelines to evaluate the evidence for donor site selection based on minimising the associated donor site morbidity and optimising patient functionality postoperative. The fibula is associated with the greatest potential risk for wound healing complications. Fibula and scapula harvest has the potential to have a significant impact on physical performance. The iliac crest is most favourable in terms of aesthetic scar healing outcomes. Overall, however, the quality and quantity of evidence for all donor sites is limited. Each site is associated with specific complications and morbidity, of which the surgeon and patient must both be aware. Whilst a cross-sectional informed opinion of the likely advantages/disadvantages of one donor site over another can thus be made, there are few head-to-head studies available that directly compare donor sites.

    Abstract Quality of life (QOL) has become a primary determinant of the treatment outcome. There is a poor evidence base regarding the QOL implications of free flap harvest from the various different osseous composite donor sites. This prospective study assessed the impact of free flap harvest on QOL and compared QOL morbidity between fibula, scapula, and iliac crest (deep circumflex iliac artery; DCIA) donor sites in head and neck reconstructive surgery. This was a single-site prospective cohort clinical research study. Fifty-nine patients were recruited between 2017 and 2021; 30 underwent fibula flap reconstructive surgery, 17 scapula flap, and 12 DCIA flap. The patients were assessed using the University of Washington Quality of Life Questionnaire version 4 (UW-QOL v4) preoperatively and again at >12 months postoperatively. The results showed no significant change in the mean global QOL score postoperatively when compared to the preoperative baseline in any of the donor site groups. However, the mean postoperative scores for the appearance domain were significantly lower than the preoperative scores in all of the donor site groups. In addition, fibula flap patients had significantly reduced physical activity and recreation QOL domain scores postoperatively when compared to the preoperative scores.

    Abstract Prosthetic replacements in the 19th and early 20th century were superseded by pedicled flaps and obturators. These have subsequently been superseded by free tissue transfer which currently is the mainstay of reconstructive jaw surgery. Although malignant and benign processes of the jaws are the predominant cause of segmental defects, a significant proportion still occurs due to trauma, or even iatrogenic causes such as radiotherapy. The varied aetiologies demand a nuanced approach to reconstruction and although the techniques remain similar the timing can be quite different. The maxilla and the mandible are both amenable to composite reconstruction with bone. The fibula, iliac crest, scapula, distal radius and medial femoral condyle are the most commonly utilised donor sites for vascularised reconstruction. Each has strengths and weaknesses and the requirements of the defect, and patient preference should outweigh surgeon preference. Osseointegrated implants allow reliable rehabilitation of the dentition by anchoring facial prostheses. Their integration into composite flaps is highly reliable although soft tissue management can be challenging. Virtual surgical planning and 3D printing have already impacted on the surgical workflow and improved the reliability and accuracy of results. If this technology can be applied to tissue typing and human tissue (instead of just plastic and metal) a fully prefabricated and vascularised jaw without donor site morbidity would be the ultimate aim.

    Abstract Resorption of alveolar bone following tooth extraction is a physiological process that can often prevent the placement of dental implants due to the limited bone remaining. In severe cases, vertical bone augmentation, which aims to restore bone in an extraskeletal dimension (outside of the skeletal envelope), is required prior to implant placement. While current treatment strategies rely on autologous grafts, or "Guided Bone Regeneration" involving the placement of particulate bone grafting biomaterials under a protective membrane, the field is shifting to patient-matched solutions. Herein, we describe the various steps required for modeling the patient data, creating the patient-matched scaffold geometry and 3D-printing using the biodegradable polymer polycaprolactone for application in the oro-dental and craniofacial areas.

    Abstract Odontogenic infections can become life-threatening if not managed in a timely manner, and they increase the physical cost of treatment to the patient and the financial cost to the public health system. We investigated the number of admissions to a Queensland tertiary hospital within a decade, and differences in the patients' characteristics, severity at presentation, and clinical outcomes. We compared patients with odontogenic infections who were taken to theatre at the Royal Brisbane & Women's Hospital (RBWH) between January 2003 and December 2004 with those treated between January 2013 and December 2014, a total of 292. Data on demographics, presentation, previous history, antimicrobial treatment, and admissions, were collated and analysed. There were no significant differences in demographics. In the 2013/2014 group there was a two-fold increase in infections related to lower third molars (p=0.001), a 50% increase in trismus (p=0.001), and a 20% increase in submandibular swelling (p=0.010). The percentage of patients admitted to the intensive care unit (ICU) was three and a half times higher in the 2013/2014 group (p=0.001). The presentation of odontogenic infections has increased in the decade from 2003/2004 to 2013/2014. Measures of the severity of disease have increased, while the basic characteristics of the patients have remained constant. Improved primary preventative measures and early interventions are therefore needed to alleviate the burden that these infections place on the public health system.

    Abstract The bleeding risk in individuals with inherited bleeding disorders (IBDs) during exodontia is traditionally managed with perioperative coagulation factors and/or desmopressin, in conjunction with systemic and topical perioperative tranexamic acid and meticulous primary closure. Factor replacement is costly, requires specialist input, and carries a risk of developing factor VIII (FVIII) inhibitors. This prospective study was performed to determine whether the use of a standardized Floseal and anti-fibrinolytic protocol could reduce postoperative bleeding in patients with IBDs undergoing dental extraction, as compared to factor replacement. All patients >18 years old attending Queensland Haemophilia Centre between November 2014 and July 2019 who required dental extractions were referred to the Oral and Maxillofacial Unit. Patients were consented for intraoperative Floseal administration instead of factor replacement. All other operative measures remained the same. The bleed rate was assessed against a historical control cohort. There were 34 extraction events in 32 patients. Four of the patients reported postoperative bleeding requiring factor supplementation or desmopressin; the bleeding rate was 11.8%. While not statistically significant, this was a reduction in the bleed rate compared to the traditional protocol (P = 0.35). Third molar extractions were 10.33 times more likely to cause postoperative bleeding (P = 0.018). The Floseal protocol was equipotent to the traditional perioperative factor replacement protocol. Floseal use is more economical, eliminates the risk of peri-procedural FVIII inhibitor development, and provides a haemostatic option for patients with very rare factor deficiencies, pre-existing clotting factor inhibitors, and those with anaphylaxis to clotting concentrates.
