Introduction. Intraosseous vascular malformation could be life-threatening due to uncontrolled hemorrhage after tooth extraction. According to biological behavior of this lesion, adequate diagnostic and treatment strategies are necessary in order to avoid possible complications. We reported cone beam computed tomography (CBCT) planning of an urgent en bloc resection of an intraosseous venous malformation by piezoelectric knife. Case report. A 55-year-old man was submitted to CBCT planning followed by piezoelectric knife resection of an intraosseous focal venous malformation of the mandibular body. Immediate reconstruction of the defect using iliac bone free graft was performed. The surgical treatment was uneventful and a 2-year follow-up revealed no signs of recurrence. Conclusion. Piezoelectric knife could provide precise, safe and bloodless procedure which is especially important in this pathology. Advantages of this technique are: lower risk of damaging soft tissue structures, precise osteotomy and bloodless surgery. Moreover, using piezosurgery bone knife, blood transfusion and blood transmitted diseases could be avoided. This case highlights the importance of CBCT as planning tool for resection of the mandible, using piezoelectric knife as safe method to achieve bloodless surgery. © 2017, Institut za Vojnomedicinske Naucne Informacije/Documentaciju.

Introduction No consensus has been reached yet on the surgical approach for treatment of condylar fractures. Objective The aim of this study was to present modified Risdon approach (without facial nerve identification) in the treatment of subcondylar mandibular fractures. Method This is a retrospective study of a period 2005–2012. During this seven-year period, 25 condylar mandibular fractures in 22 men and three women (19–68 years old) were treated by modified Risdon approach without identifying the facial nerve. The main inclusion criterion was subcondylar fracture according to Lindahl classification. Results No additional morbidity related to postoperative complications, such as infection or salivary fistula, was observed in this series. Only two (8%) patients developed temporary weakness of the marginal branch of the facial nerve, which resolved six weeks postoperatively. Each patient achieved good mouth opening postoperatively. Scar was camouflaged in the first cervical wrinkle. Two patients developed temporomandibular joint dysfunction. No patient had postoperative occlusal disturbance. In all of the patients good aesthetic result was achieved in a two-year follow-up. Conclusion In comparison with techniques described in the literature, the main advantages of the modified Risdon approach are the following: no need for facial vessels identification; direct, fast, and safe approach to mandibular angle and subcondylar region; relatively simple surgical technique and good cosmetic result – due to aesthetically placed incision. This approach could be recommended for subcondylar fracture as a simplified and safe procedure. © 2016, Serbia Medical Society. All rights reserved.

Background/Objectives: Integra Dermal Regeneration Template (IDRT) has emerged as a viable reconstructive option in exposed avascular structures, such as exposed bone devoid of periosteum. This systematic review aimed at examining success rates by comparing different wound types and their characteristics, as well as the surgical methods involved. Methods: A systematic review was conducted to identify studies using IDRT in the reconstruction of defects with exposed bone devoid of periosteum. Primary outcomes of interest were IDRT and skin graft success rates, followed by patient and wound characteristics, and different surgical methods used. The results were accompanied by an illustrative case report of IDRT-based hand reconstruction after a deep burn injury. Results: The review included 40 studies, with a total of 202 individual defects. The primary indication for IDRT-based reconstruction was post-oncologic defects in the elderly population. Although surgeons mostly used burring/fenestration as a bone preparation method prior to IDRT placement, decorticated bones showed faster grafting time (23.8 vs. 27.9 days). The average success rate of IDRT was 87.54% (±25.9), with an excellent IDRT take rate (100%) observed in more than 50% of cases. In the majority of cases (95.5%), the skin graft acceptance rate was deemed to be higher than 95%, with an average graft take of 98.8%. Conclusions: The results of this review support the use of IDRT in managing complex defects involving exposed bone, offering fast coverage with good functional restoration, without any donor site morbidity. Additionally, bone preparation methods also play an important role in IDRT-based reconstruction by shortening the grafting time. © 2025 by the authors.

Introduction The radial forearm free flap has an important role in reconstruction of the oncologic defects in the region of head and neck. Objective The aim was to present and evaluate clinical experience and results in the radial forearm free transfer for intraoral reconstructions after resections due to malignancies. Methods This article illustrates the versatility and reliability of forearm single donor site in 21 patients with a variety of intraoral oncologic defects who underwent immediate (19 patients, 90.5%) or delayed (2 patients, 9.5%) reconstruction using free flaps from the radial forearm. Fascio-cutaneous flaps were used in patients with floor of the mouth (6 cases), buccal mucosa (5 cases), lip (1 case) and a retromolar triangle (2 cases) defects, or after hemiglossectomy (7 cases). In addition, the palmaris longus tendon was included with the flap in 2 patients that required oral sphincter reconstruction. Results An overall success rate was 90.5%. Flap failures were detected in two (9.5%) patients, in one patient due to late ischemic necrosis, which appeared one week after the surgery, and in another patient due to venous congestion, which could not be salvaged after immediate re-exploration. Two patients required re-exploration due to vein thrombosis. The donor site healed uneventfully in all patients, except one, who had partial loss of skin graft. Conclusion The radial forearm free flap is, due to multiple advantages, an acceptable method for reconstructions after resection of intraoral malignancies. © 2015, Serbia Medical Society.
