OBJECTIVES: 3D virtual surgical planning (VSP) and guided surgery has been proven to be an effective tool for resection and reconstruction of the mandible. Currently, most widely used 3D VSP approaches to mandibular resection do not include detailed tumour information in the VSP. This manuscript presents a strategy where the aim was to incorporate tumour visualisation into the 3D virtual plan. Three-dimensional VSP of the mandibular resections was based on the fusion of CT and MRI data which was subsequently applied in clinical practice...

PURPOSE: Ablative oncological surgery to treat head-and-neck cancer often triggers a requirement for jaw reconstruction. Modern surgical procedures using free microvascular flaps afford acceptable outcomes in terms of restoration of bony and soft tissue defects. A fibula free flap is often the preferred flap, as the bone length is considerable and a two-surgeon approach is possible. Dental implants play important roles in functional rehabilitation. Our aim was to evaluate the survival of dental implants placed in reconstructed areas after transfer of fibula tissue to the jaw...

BACKGROUND: Defects following resection of tumors in the head and neck region are complex; more detailed and defect-specific reconstruction would likely result in better functional and cosmetic outcomes. The objectives of our study were: 1) to improve the understanding of the two- and three-dimensional nature of oral cavity and oropharyngeal defects following oncological resection and 2) to assess the geometric dimensions and the shapes of fasciocutaneous free flaps and locoregional tissue flaps required for reconstruction of these defects...

BACKGROUND: Traditional free flap reconstruction of complex intraoral defects often uses large lip-splitting incisions. To reduce morbidity and preserve aesthetics, we have adopted a more technically demanding visor technique obviating an incision through the lower lip through which the resection and reconstruction are performed. METHODS: A retrospective review was performed of patients who underwent free flap reconstruction of intraoral defects over 7 years by a single plastic surgeon (C...

Microvascular reconstruction of ablative defects has become a mainstay of contemporary management of head and neck cancer patients. These techniques offer myriad tissue options that vary in character, volume, and components and have vastly improved the esthetic and functional outcomes achieved in this patient population. Although consensus exists regarding the reliability and functional and esthetic benefits of free tissue transfer, the same cannot be said for oncologic outcomes. The increase in resources required for the routine use of free tissue transfer has led to asking this question-Do vascularized free flaps allow for increased surgical margins and improvements in oncologic outcomes?...

In the oral cavity, the tongue is the anatomic subsite most commonly involved by invasive squamous cell carcinoma. Current treatment protocols often require significant tissue resection to achieve adequate negative margins and optimal local tumor control. Reconstruction of the tongue while preserving and/or restoring its critical vocal, chewing, and swallowing functions remains one of the major challenges in head and neck oncologic surgery. We investigated the in vitro feasibility of fabricating a novel combinatorial construct using porcine small intestinal submucosa extracellular matrix (SIS-ECM) and human gingiva-derived mesenchymal stem cells (GMSCs) as a GMSC/SIS-ECM tissue graft for the tongue reconstruction...

BACKGROUND: Reconstruction of defects after extirpation of head and neck cancer is a highly challenging and complex surgical undertaking. Commonly used techniques, e.g., the radial forearm flap, the anterior lateral thigh flap, or flaps harvested from the chest-deltopectoral or pectoralis major-share numerous disadvantages, such as donor-site morbidity, poor color matching for cutaneous reconstruction, and excessive tissue bulk. The use of a supraclavicular artery island flap is a long-forgotten but increasingly popular option for reconstruction in the head and neck area...

BACKGROUND: Surgical management of head and neck cancer is resource intensive and physiologically demanding. In patients with incurable disease, although the indications for surgery are not well defined, palliative benefit can be significant. The goal of this investigation was to compare outcomes of patients who underwent resection and reconstruction of head and neck cancer with curative intent with those who underwent similar procedures with palliative intent. METHODS: A retrospective review of patients who underwent reconstruction for head and neck cancer between 2008 and 2014 was conducted...

Oral cavity carcinoma (OCC) remains a major cause of morbidity and mortality in patients with head and neck cancer. Although the incidence has decreased over the last decade, outcomes remain stagnant with only a 5% improvement in overall survival in the last 20 years. Although surgical resection remains the primary treatment modality, several areas of controversy exist with regard to work-up, management of the primary and neck tumors, and adjuvant therapy. As surgical techniques evolve, so has the delivery of radiotherapy and systemic treatment, which have helped to improve the outcomes for patients with advanced disease...

BACKGROUND: Buccinator myomucosal flaps are routinely used for oral cavity reconstruction and are indicated mainly in patients classified as having stage N0 cancer. This purpose of this study was to investigate whether preservation of the vascular pedicle of the flap (facial artery and vein) during stadiative neck dissection alters the oncologic safety in these patients. METHODS: Fifty patients underwent resection of T1 to 3, N0 squamous cell carcinoma of the tongue or floor of the mouth, stadiative neck dissection, and reconstruction with a facial artery musculomucosal (FAMM) flap were retrospectively analyzed concerning rate of occult neck metastasis and recurrences...

The restoration of function after oncologic surgery of the oral cavity constitutes one of the major challenges facing head and neck oncology. Within the general objective of securing esthetic as well as functional reconstructions, dental rehabilitation is crucial for achieving a good outcome. Adequate dental rehabilitation allows the patient to chew food and considerably improves speech and swallowing. These reconstructions will be driven biologically or prosthetically following surgical design and outcome.
