Revascularization of the tongue by radial forearm flow-through flap
The concept of a flow-through flap refers to a free flap in which both the proximal and distal ends of the vascular pedicle are anastomosed to provide blood flow to the distal tissues. The purpose of this paper is to highlight the use of this technique, which may be useful in selected cases of head and neck reconstruction. In certain situations, like bilateral resection of the base of the tongue involving both lingual arteries, the application of a flow-through forearm free flap can provide an anatomical and functional restoration of the defect while revascularizing the anterior two-thirds of the tongue.

The effect of residual bone height and membrane thickness on sinus membrane perforation in crestal sinus grafting: A prospective clinical study
This study sought to determine the rate of sinus membrane perforation in patients undergoing crestal sinus grafting, as well as the effect of Schneiderian membrane thickness and residual bone height (RBH) on membrane perforation, using cone beam computed tomography. The study included 25 patients undergoing 44 crestal sinus grafting procedures. The sites for crestal sinus grafting were divided into a control group (RBH ≥5mm) and a test group (RBH (Source: International Journal of Oral and Maxillofacial Surgery)

Quantitative evaluation of symmetry after navigation-guided surgical recontouring of zygomatic fibrous dysplasia: a comparative study
Zygomatic fibrous dysplasia is a slowly progressive disorder of bone, which commonly causes facial asymmetry. Precise surgical recontouring can effectively improve facial aesthetics. The aim of this study was to quantitatively evaluate the effectiveness of surgical navigation guidance in correcting zygomatic asymmetry. The study included 26 patients with unilateral zygomatic fibrous dysplasia who underwent bony recontouring. They were divided into two groups according to the use of intraoperative surgical navigation (navigation group and conventional group; n=13 in each group).

Digital surface scanning in flap perfusion
Monitoring vascular perfusion of transferred tissue is essential in reconstructive surgery to recognize early flap failure. The aim of this study was to evaluate the ability of a digital surface scanner to detect vascular perfusion disorders through the monitoring of skin colour changes. A total of 160 surface scans of the forearm skin were performed with a TRIOS 3D scanner. Vascular compromise was simulated at different time-points by intermittent occlusion of the blood supply to the forearm skin (first the arterial blood supply and then the venous blood supply).

Will they fit? Determinants of the adaptability of stock TMJ prostheses where custom TMJ prostheses were utilized
Currently only two alloplastic temporomandibular joint (TMJ) total joint replacement (TJR) systems are available in the United States. The aim of this study was to define variables that determine whether a Biomet stock prosthesis could have been used to reconstruct a TMJ previously reconstructed with a TMJ Concepts patient-fitted prosthesis. All of the TMJ Concepts prostheses placed between 2010 and 2018 at the University of Texas – Health at San Antonio were analyzed retrospectively. There were 128 cases (241 joints) with intact stereolithographic models analyzed for successful adaptation of the Biomet stock TMJ pro...

Three-dimensional CAD/CAM reconstruction of the iliac bone following DCIA composite flap harvest
This article reports a new technique to restore iliac bone integrity with a customized titanium device designed by CAD/CAM, in patients undergoing deep circumflex iliac artery (DCIA) composite flap harvest. Eight consecutive patients who underwent the repair of major head and neck defects with DCIA flaps were enrolled retrospectively. Computed tomography scans of the pelvis were obtained preoperatively. Starting from DICOM data, each personalized device was designed using modelling software and was finally made by additive manufacturing using a laser sintering machine.

Combined reconstruction plate fixation and submandibular gland translocation for the management of medication-related osteonecrosis of the mandible
The aim of this study was to summarize the clinical outcomes of patients with stage 3 mandibular medication-related osteonecrosis of the jaw (MRONJ) treated using reconstruction plate fixation and ipsilateral submandibular gland translocation after mandibulectomy. The medical records of patients with stage 3 mandibular MRONJ treated using the above surgical method between September 2014 and July 2019 were reviewed. Of a total of 27 patients included in this study, 23 (85.2%) experienced primary wound healing. (Source: International Journal of Oral and Maxillofacial Surgery)

Malignant transformation of oral proliferative verrucous leukoplakia: a series of 48 patients with suggestions for management
Proliferative verrucous leukoplakia (PVL) is a rare and refractory form of oral mucosal leukoplakia of unknown origin, characterized by high rates of malignant transformation. Different diagnostic criteria, terminologies, and therapeutic approaches have been proposed since the first report in 1985. There remains no general agreement regarding the clinical and histological diagnosis, prevention, and correct management of this disease. This retrospective study investigated 48 patients affected by PVL showing at least one malignant transformation and followed up at 2-month intervals. (Source: International Journal of Oral and...

Derek M. Steinbacher, Aesthetic Orthognathic Surgery and Rhinoplasty, Wiley Blackwell 2019
Given the plethora of books devoted to orthognathic surgery and rhinoplasty over the past four decades, it is intriguing to see a text that covers both domains of surgery. As the title begins with the adjective, “aesthetic”, it begs the question as to what additional information would be offered that has not already been covered in detail, given that facial balance has been a central aim of jaw surgery since its evolution and obviously, cosmesis in rhinoplasty has been paramount.
