    ABSTRACT: Since the 1980s, bone free flaps have been used to reconstruct the maxilla and the mandible. The vascular pedicle, through the supply of nutritional substances and drugs from the bloodstream, ensures the vitality of the flap, rapid bone integration, and reduced risk of infection.However, due to many surgeons' concerns about orocervical and orosinusal fistulas and infections, bone flaps are usually buried and protected by mucosal flaps or a second skin flap whenever it is not possible to harvest a skin paddle together with the bone flap.The authors, convinced that naked bone free flaps, if well vascularized, are capable of healing and repairing the osteomucosal deficit on their own, with no risk of infection or fistulas, began to harvest, for oral reconstructions, naked bone flaps, that is, bone flaps covered only by a muscle layer 5 to 20 mm thick.In this study, the authors present a review of their experience in oral cavity reconstructions by harvesting naked and covered bone free flaps, retrospectively evaluating the occurrence of major and minor, early and late complications, associated with the different reconstructive technique.

    ABSTRACT: The aim of this study was to test our approach based on the use of calvarial graft and extraoral approach, in treatment of severe mandibular atrophies with implant surgery and prosthetic rehabilitation. We selected 6 patients, 4 females and 2 males, completely edentulous with a severe mandibular atrophy (class VI Cawood and Howell classification). Mean age of patients was 63 years, ranging from 60 to 67 years. Mandibles were reconstructed with a submental incision with calvarial bone graft harvested from parietal area. After a mean of 4.2 months, each patient received 4 implants, and after a mean of 4.67 months, implants were loaded. No complications occurred in donor site or on the mandible, and all patients recovered well. No extraoral scar occurred. A total of 25 implants were inserted, and, with exception of an early failure and successive replacement, all implants were osseointegrated at successive visits. After 1-year follow-up, our analysis showed 100% implants survival and correct fit and success of prosthetic rehabilitation. Results of this study showed an uneventful recovery for all patients with our approach and reduced healing time of bone graft. So extraoral approach with submental incision and calvarial graft is a reliable method in reconstruction of atrophic mandibles, and staged implant surgery is suggested.

    ABSTRACT: Treatment of orbital floor fracture is a subject of great interest in maxillofacial surgery. Many materials have been described for its reconstruction.In this article, the authors report a case of a patient who, 7 years from a previous orbital floor fracture and treatment with silastic sheet, presented herself to their clinic for the failure of the material used for its reconstruction and a skin fistula.Orbital floor repair with silastic sheet is an old method that no one uses anymore, but we still observe cases of late complications with this material. So a fine knowledge of silastic sheet complications is needed for young surgeons.The authors report the case and perform a literature review about the use of more modern biomaterials for orbital floor reconstruction.

    ABSTRACT: Background: Frontal bossing is a malformation characterized by peculiar prominent forehead, and commonly it can be associated with cranial synostosis and endocrine disorder; however, nonsyndromic conditions are described as well.Literature controversies on proper frontal bossing surgical treatment showed evidence of 2 main surgical procedures: frontal bone reshaping and bone en bloc mobilization.A decision-making criterion between these 2 techniques has never been described in literature. Methods: In this paper, the authors introduce their brand-new analytic method for decision-making between bur shaping and en bloc mobilization in frontal bossing treatment, and describe a successful case of a nonsyndromic frontal bossing patient, treated with their unconventional surgical technique. Results: Our analytic method indicated that bur shaping was not indicated in this particular case: aggressive remodeling of excessive thin wall could lead to sinus perforation, which could turn into unsatisfied aesthetic and functional outcome.So we planned for a bilateral orbitofrontal en bloc reposition, followed by internal rigid fixation. No postoperative complications occurred. Postoperative CT scan revealed good bone repositioning and recovery. Conclusions: The authors explained their analytic method based on careful presurgical CT-scan measurements for decision-making between bur shaping and en bloc mobilization.

    ABSTRACT: Nasal defects resulting from tumor excision can be classified according to tissues involved, such as skin, cartilage, and bone. Although in the case of "simple" defects, reconstruction with loco-regional flap eventually associated with cartilage grafts can lead to satisfactory results; in the case of total or partial rhinectomy, a minimum of 3 and a maximum of 7 operations have to be performed in the current series to achieve an acceptable end result. We present the case of a total rhinectomy reconstruction in a single-step procedure with an osteocutaneous forearm free flap (RFOFF). A 50-year-old man underwent total rhinectomy to excise a pathologically proven T4aN0 moderately differentiated squamous cell carcinoma of the nose; contemporary single-step reconstruction with an RFOFF was performed. Adjuvant radiotherapy was performed. At 18 months of follow-up, the patient is free of disease and no postirradiation flap damage has been experienced; the flap notably did not appear to be bulky. We believe that the RFOFF is morphologically and functionally better than other flaps owing to its capability to adapt to the new environments of the nasal cavity, and to avoid, when possible, a three-dimensional reconstruction of the same.

    ABSTRACT: The objective of this study was to describe the orthognathic surgery techniques for the treatment of occlusal anomalies in those patients who underwent complex maxillomandibular reconstruction with bony free flap. The authors describe their personal technique developed over years of experience with reconstruction of mandibular defects with bony free flaps. The outcomes in these patients who were treated according to our surgical planning were completely satisfying, with a 100% stability of the treated bones. Orthognathic procedure on bony free flaps for the reconstruction of mandibular defects is nowadays accepted. Patients who underwent major mandibular destruction due to oncologic disease or trauma outcomes can now benefit from this technique.

    ABSTRACT: Starting from the 1980s, with the advent of microsurgery, microvascular flaps are used for the reconstruction of wide and complex bone defects of the maxillomandibular district. Compared with conventional and implant-supported prostheses, the free flaps allow aesthetic-functional rehabilitations more adapt to answer to problems that these wide disablements involve. The anatomic characteristics of the crest flap make it one of the best available flap in the maxillomandibular bone reconstruction. The authors introduce a retrospective analysis of their own experience in the reconstruction of wide and complex bone defects of the maxillomandibular district. Specifically, the attention is focused on the use of the iliac crest flap. The surgical technique of flap preparation is discussed. Moreover, a review of results from international studies about the morbidity of the donor site is presented and compared with own experience. As reported in the literature, the iliac crest flap donor site may encounter several complications. Among these, chronic pain, loss of regional sensibility or paresthesias, hematoma, seroma, walking troubles, unaesthetic scars, abdominal hernia, and loss of the normal bone profile of the hip. At present, the use of the iliac crest free flap in the microvascular reconstruction of the complex deficits of the maxillomandibular district represents a well-established method in the experience of the maxillofacial surgeon. Several information about results obtained in the maxillomandibular rehabilitation are available from the literature; however, little attention has been addressed to complications and morbidity of the donor site. Such aspect will be discussed in this work.

    ABSTRACT: Composite tissue defects of the mandible and maxilla, after resection of head and neck malignancies, osteoradionecrosis, malformations, or traumas, cause functional and aesthetic problems. Nowadays, microvascular free flaps represent the main choice for the reconstruction of these defects. Among the various flaps proposed, the scapula flap has favorable characteristics that make it suitable for bone, soft tissue, or combined defects. We report 7 cases of reconstruction of complex maxillofacial defects with subscapular system flaps. The patients treated had Romberg syndrome (1 case), malignant tumors (5 cases), and result of previous trauma (1 case).Location of deficit was the maxilla (3 cases), the mandible (2 case), the ethmoidal-maxillary region (1 case) and the upper and middle thirds of the face in the last case. In 2 cases, a parascapular system flap was used; in 5 cases, a composite flap with latissimus dorsi muscle and scapular bone. Neither failure of the harvested flaps nor complications in the donor site were evidenced. A good aesthetic and functional outcome was obtained in all cases. : Many free flaps have been proposed for the reconstruction of defects in the maxillofacial region such as fibula, deep circumflex iliac artery, scapula, among the bone flaps; and forearm, rectus abdominis, and anterolateral thigh, among the soft tissue flaps. The choice of the flap to use depends on the length of the bone defect and the amount of soft tissues required. The subscapular system has the advantage of providing different flaps based on the same pedicle. The osteofasciocutaneous scapular free flap, in particular, allows wide mobility of soft tissues (parascapular flap) with respect to its bone component (scapular bone), resulting suitable for defects of large size involving both the soft tissues and the bone. Although the fibula flap and the deep circumflex iliac artery flap remain the first choice for bone reconstructions of the mandible and maxilla, the scapula flap has some features that make its use extremely advantageous in some circumstances. In particular, we advocate the use of the osteomuscular latissimus dorsi-scapula flap for reconstruction of large-volume defects involving the bone and soft tissues, whereas fasciocutaneous parascapular flaps represent a valid alternative to forearm flap and anterolateral thigh flap in the reconstruction of soft tissue defects.

    ABSTRACT: Intraosseous hemangiomas are classified as benign tumors of vascular nature. Some authors describe them as hamartomas. They originate and expand inside bone structures. They are usually congenital, rarely of posttraumatic origin. In the Maxillo-Facial Surgery departments of the Universities of Rome "La Sapienza" and "Tor Vergata," from 1990 to 2004, 11 cases of intraosseous hemangioma have been diagnosed. In 6 cases, the neoplasm localized in the zygomatic region; in 3 cases, at the mandible level; in 1 patient, in the maxillary site; and in 1 patient, in the frontal bone. Literature review and the case of a male patient affected by left orbitozygomatic hemangioma are described.

    ABSTRACT: This work focuses on the use of revascularized free flaps for the reconstruction of the major defects of the mandible after the removal of advanced-stage tumors in irradiated patients. It uses three representative cases to study the problems of complex patients and the possible reconstructive options. The cases, all three young patients (two females and one male), had undergone a mandibulectomy and adjuvant radiotherapy for malignant neoplasms. In each case, secondary reconstruction of the mandible and soft tissue was necessary and was performed using microvascular free flaps. An osteomyocutaneous iliac crest free flap was used in two cases, whereas a double flap (fibula free flap + rectus abdominis free flap) was used in the other case. In all three cases, after the microvascular reconstruction, an orthognathic procedure was performed to obtain the correct maxillomandibular relationship. The advantages and disadvantages of the various techniques used are discussed.
