Vinay V Kumar, P C Jacob, Vikram Kekatpure, Naveen Hedne, Felix P Koch, Moni A Kuriakose
AIM: The aim of this clinical paper is to introduce a technique to plan for functional maxillofacial reconstructions. MATERIALS AND METHODS: Preoperative dental casts were made of the patient and mock surgery performed on the casts. A fibula analogue was then placed in an ideal functional reconstruction position. New dentures were fabricated on the fibula analogue and drill holes for the placement of implants were placed through the denture. This denture formed as a guide to position the fibula transplant during surgery...

PURPOSE: Resections in the posterior component of the oral cavity usually lead to severe functional compromise and lower quality of life for patients. Notable advances in reconstruction of the posterior part of the mouth and of the oropharynx have occurred in recent decades. The anatomic and physiologic rehabilitation of the defect to a reasonable outcome with low morbidity and mortality remains the founding basis of any surgical reconstruction, which also holds true for oral oropharyngeal and retromaxillary reconstructions...

Ballistic injuries of oral and maxillofacial region are usually fatal due to close propinquity with the vital structures. The severity of injury depends on the caliber of the weapon used and distance from which the patient is shot. The preliminary care of facial ballistic wounds strictly adheres to the basics of trauma resuscitation. Early and appropriate surgical management has proved to be influential on the final outcome and esthetic result. Treatment of facial gunshot wounds should be planned and carried out carefully to avoid esthetic complications...

For the first time it was demonstrated that an osteoinductive calcium phosphate-based putty is effective in the restoration of complex maxillofacial defects. In these defects, adequate mechanical confinement by multiple bony walls and osteoconduction from multiple surfaces are usually lacking. This study compares the efficacy of a microstructured beta-tricalcium phosphate (β-TCP) putty with autologous bone for the repair of alveolar cleft defects. A total of 10 Dutch milk goats were operated on in a split-mouth study design in which two-wall bony alveolar clefts were created and successively repaired with autologous bone (the gold standard) at one side and β-TCP putty at the other...

BACKGROUND: Mandibular pseudocarcinomatous hyperplasia is a rare and generally benign pathology. We report on one of these rare cases. CASE PRESENTATION: The case history of a 73-year-old white man stated that he had a carcinoma of the oropharynx, which was primarily treated with radiotherapy and chemotherapy 4 years prior. As a result of radiotherapy he developed an osteoradionecrosis of his mandible and a consecutive pathological fracture of his left mandibular angle...

PURPOSE: Relevant reports about oral candidiasis status and prevention measures after free flap surgery for the oral and maxillofacial region are limited. The present study explored oral candidiasis status after free flap surgery and its prevention through a prospective comparative study. PATIENTS AND METHODS: One hundred four patients were randomized to a control group (n = 54) and an experimental group (n = 50). Compared with the control group, the experimental group was provided an additional 3% sodium bicarbonate saline solution for oral care after free flap surgery...

BACKGROUND: Although hyperbaric oxygen therapy (HBOT) is used to treat chronic radiation tissue injury, clinical evidence supporting its use in maxillary bone osteoradionecrosis (ORN) is lacking. Therefore, the purpose of this study was to report our results of collected patient outcomes from a single center's large experience using HBOT to treat maxillary bone ORN. METHODS: From 1999 to 2015, 21 patients received treatment for maxillary bone ORN at our center. The medical records were retrospectively reviewed for the following variables: age, sex, comorbidities, tumor stage and site, previous surgery, previous radiotherapy or chemoradiation therapy, HBOT data, response to treatment and further management...

PURPOSE: The purpose of this study was to describe the authors' experience using the Yu flap, a rarely reported reconstructive technique that is an excellent method for lower lip reconstruction after sustaining large defects. MATERIALS AND METHODS: An observational retrospective study was designed to record all patients from 2010 through 2015 who had any lower lip disease that required wide resection and subsequent lip reconstruction using local flaps. The sample was supplied from the operating room database of the Department of Oral and Maxillofacial Surgery at Rio Hortega University Hospital (Valladolid, Spain)...

THE PROBLEM: Dislocated intra-articular fractures of the distal radius are operatively treated to achieve anatomical reconstruction of the joint. In complex distal radial fractures with multiple joint fragments, fixation with angular stable plates alone may be technically challenging. Smaller fragments, such as the lip of ulnopalmar joint, are often difficult to control. THE SOLUTION: The supplementary application of mini plates, as employed in maxillofacial surgery, is a helpful tool for reduction and fixation...

Maxillofacial reconstruction surgery largely relies on the use of microsurgical free transfer techniques. Head and neck cancer surgery and ballistic injuries may lead to significant losses of multitissular substances. Even when the free transfer is successful and the microvascular critical phase is resolved, some functions or anatomic structures may not have been properly restored or have worsened. Any plastic surgery technique may be used to improve an unfavorable functional or aesthetic result after free flap reconstruction...

INTRODUCTION: In reconstruction of post-traumatic craniofacial defects Palacos R-40 is mostly used by neurosurgeons and by maxillofacial surgeons after tumor removal with consequently noticeable irregularities on the shape of the cranial region and face. We harvested customized adipodermal (AD) graft in low inguinal region and use it as an inlay autologous graft for surface irregularities correction with a 100% survival and without noticeable reduction of the graft volume. MATERIAL AND METHODS: Between 2009 and 2015, an adipodermal gaft was used in 5 cases of craniofacial post-traumatic defects, 3 of which were due to Palacos R-40 cranial reconstruction and 2 connected to maxillofacial tumor removal and post-traumatic reconstruction...

Traumatic dislocation of the mandibular condyle into the middle cranial fossa is an extremely rare complication of maxillofacial injury. The rarity of this injury has led researchers to propose a set of anatomic features that might explain this injury. These features include a small rounded condylar head, hyper-pneumatization of the temporal bone, a thin roof over the glenoid fossa, and missing posterior teeth. The greatest risk factor for this injury is a blow to the chin when the mouth is open without fracture of the condyle (and therefore no dissipation of the forces)...
