ABSTRACT

Maxillo-mandibular asymmetry has numerous aetiologies: congenital, traumatic, iatrogenic and post-oncologic. Patients with congenital dentofacial malformations are generally submitted to orthognathic surgery and/or additional procedures (genioplasty, alloplastic implants) with satisfactory results. However, despite achieving skeletal symmetry, noticeable facial asymmetry may persist.This study was performed in 45 patients (29 women and 16 men) operated between December 2012 and June 2014. All patients were affected by maxilla-mandibular asymmetry and underwent orthognatic surgery for hard tissue correction of the deformity. Residual facial alterations were then treated with lipofilling refinement proceure. In all cases good integration of the grafted fat was observed in the recipient sites. Retrospective analysis of photographic documentation showed progressive volumetric decrease for up to approximately 6 months after surgery; after that graft volume remained relatively stable. There were no significant surgical complications, either from the fat harvest site or the reconstructed site. Mild oedema and bruising were frequent during the first post-operative week. No haematomas, infections, vascular or nervous injuries were recorded. Twenty-four patients felt the need to have a second procedure. A second fat transfer was performed in 22 cases, and a third in 2 (total of 69 procedures). Based on the observations of our study, fat grafting is a simple, effective and reproducible technique, with a high satisfaction rate and few disadvantages or complications. We demonstrated that the success of lipofilling is dependent on the treated aesthetic subunits of the face. The malar and lateral cheek regions seem to be highly favourable for fat grafting, unlike the upper and lower lips subunits. Composite procedures using orthognathic surgery and autologous fat provide the surgeon with an additional, more customisable option for patients with maxillo-mandibular malformations.

ABSTRACT

The gold standard in modern surgical treatment of patients with severe maxillo-mandibular atrophy must include the aim to achieve restoration of function and aesthetics with immediate reconstruction of the oro-mandibular defects. The medical records of 14 patients who were treated in a 5-year period (2010-2014) at our department with severe maxillary and mandibular atrophy, and reconstructed by vascularised free fibula flap were reviewed. Among the former, a total of 14 patients underwent maxillary and mandibular reconstruction using the osteoperiosteal fibula free flap. No major complications were reported. The main advantage of this technique is that it allows the formation of keratinised gengiva, which provides the best implantological options. The only disadvantage of the technique is that the wounds have to heal for second intention, and for this reason patients have to undergo strict follow-up for the first months after the operation. The aim of this article is to evaluate the efficiency of the technique in bone reconstruction after jaw resection or severe atrophy.

ABSTRACT

OBJECTIVES: Rehabilitation of maxillary edentulism with implant-supported prostheses has come into common clinical practice. Although autologous bone has osteoinductive, osteoconductive and osteogenetic properties, its use is subject to certain disadvantages such as: Increased morbidity Limited amount of bone harvested from each donor site. AIM: The aim of this study is to analyze clinical, histological and histomorphometric results of homologous bone for implantoprosthetic rehabilitation in severe atrophic jaws. PATIENTS AND METHODS: Twenty consecutive patients, 14 female and 6 males, were treated with homologous bone bank. Treatment protocol consist of: first surgycal step, trasversal and vertical volume restore, second surgycal step: screw remove, specimen biopsy and insert implant fixtures. RESULTS: Data show that Fresh Frozen Bone Allografts (FFBA) could be a valuable substitute for autologous bone, in as much as histological and histomorphometric results are widely overlapping. CONCLUSIONS: Homologous bone is a valuable option for its large availability with a low cost, good versatility, no morbidity at the donor site, shorter surgical time and hospital stay.

ABSTRACT

BACKGROUND: Obstructive sleep apnea syndrome (OSAS) is defined as repeated episodes of obstruction of the upper airway and oxygen desaturation of the arterial hemoglobin. OSAS is associated with loud snoring, excessive daytime sleepiness, cardiovascular and neurocognitive disease, increase risk of road accidents. AIM: The aim of this study is to evaluate non-surgical therapy for OSAS using a mandibular advancement device (MAD) that provides for lower jaw protrusion and for an adequate vertical opening, that allows for greater airflow. MATERIALS AND METHODS: The device was assembled using the working principles of "Herbst-like" appliances and splints of neuromuscular deprogramming of the "Federici" type used for gnathologic treatments. We selected 17 males and 4 females, with an average age of 42 years, and an average BMI of 29. Eighteen patients were treated with our oral appliance, 1 patient was treated with the orthesis proposed by Schmidt-Nowara et al and 2 patients were treated with the oral appliance proposed by Johal and Battagel. All patients used the appliance for at least 6 months. RESULTS: After treatment with the oral appliance, the posterior airway space increased (p = 0.0002); no statistically significant difference for the improvement degree of OSAS severity (p = 0.1085) was shown; an improvement was found in: AHI (p = 0.0028); Nadir O2 (p = 0.0035); TO2 < 90% (p = 0.0140); 2 patients presented with temporomandibular joint (TMJ) discomfort. CONCLUSIONS: Our MAD has proved effective in improving the polysomnographic and radiographic parameters and assures good TMJ compliance.

ABSTRACT

Pyoderma gangrenosum (PG) is an ulcerating noninfectious disease of the skin seen in 1-2% of patients with inflammatory bowel disease (IBD). The pathogenesis of PG has yet to be determined, but may be related to abnormal T cell responses and the production of TNF-α, a pathway also involved in IBD pathogenesis. Infliximab, a chimeric monoclonal antibody to TNF-α, is used to treat moderate to severe IBD and several case reports and studies suggest the efficacy of infliximab in the treatment of PG. The surgical approach to PG is reserved to a few selected cases. We report here the case of a patient with ulcerative colitis (UC) and PG localized on the left breast, treated with a simultaneous combined medical and surgical approach.

ABSTRACT

Oligodontia may compromise the harmonious development of the masticatory system. The quantity and quality of agenesis determines the type of approach and the complexity of rehabilitative therapy. We present a case of a patient affected by oligodontia and maxillo-mandibular skeletal alterations, corrected by orthodontic and orthognatic surgical treatment, assisted by prosthetic-presurgical rehabilitation of the lower arch. After surgery the occlusion was finally restored by a definitive prosthesis modeled on the presurgical one and supported by the same residual dental elements. Photographic and cephalometric analysis have shown the stability of the results at 20 years follow-up. The case presented shows that the final prosthesis on the residual teeth in patients affected by oligodontia may represent a possible alternative to implanto-prosthetic rehabilitation, presenting lower cost and requiring less time for definitive occlusal rehabilitation.

ABSTRACT

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) consists of an exposure of the jaw bone that persists for over 8 weeks in patients with positive history for bisphosphonates. Symptomatology is characterized by dull and ceaseless pain, and in advanced stages, the exposure of necrotic bone is evident, which is frequently associated with purulent secretions and faetor oris. Despite many different studies on BRONJ, there are no general guidelines to treat this disease. In this work, the authors present their experience in BRONJ conservative therapy with spiramycin by comparing the results achieved with amoxicillin and clavulanic acid. From January 1, 2008 to June 30, 2008, our department received 25 patients who were affected by osteonecrosis secondary to bisphosphonates. Thirteen had taken bisphosphonates for osteoporosis and 12 for malignancies. We divided the 25 patients into two groups: those who had not received any treatment and those who had received treatment. The first group of 13 patients had been treated only with spiramycin (S). The results from this group were only evaluated to test the efficacy of spiramycin and were not considered in the study. The second group of 12 patients had not undergone any previous treatment. This group was further divided in two groups of 6 patients each; one group was treated with spiramycin and the other with amoxicillin and clavulanic acid (ACA). The following criteria were used to evaluate the results of the study: pain, sensibility deficits, purulent secretion and bone exposure. All group results were evaluated according to the criteria chosen, and positive results were achieved in both groups S and ACA, such as reduction or disappearance of pain, sensibility deficits and purulent secretion and healing of bone exposition, although spiramycin showed itself to be more effective than the combination of amoxicillin and clavulanic acid. Spiramycin is a macrolide antibiotic with a wide spectrum of activity against Streptococci, Pneumococci, Diplococci, Gonococci and Staphylococci, which are typical in BRONJ. No resistance was indicated. Administration of the antibiotics can be intravenous, intramuscular, rectal or oral, which remains the most frequently used since spiramycin elimination also occurs with saliva and the antibiotic reaches high concentrations in the oral cavity where BRONJ is situated. Good compliance to the spiramycin regimen was observed in all three groups, with a general improvement in all of the parameters considered. In only two cases did patients have to undergo surgical curettage. The results showed that spiramycin can be a first choice drug in the treatment of BRONJ, and it should be strongly considered for patients where previous antibiotic therapy did not prove to be effective.

ABSTRACT

The antiphospholipid syndrome is a pathological condition characterized by recurrent thrombotic manifestations in venous and/or arterial vascular systems and by peculiar laboratory findings as anticardiolipin antibodies and/or positive lupus anticoagulant. We present a case of massive pedicle thrombosis of a free anterolateral thigh perforator flap used for tongue reconstruction following hemiglossectomy in a patient with antiphospholipid syndrome, which compelled us to an immediate second reconstruction choice with a radial forearm free flap. This case is an example of how this syndrome, especially if unknown before surgery, can influence the outcome of microsurgical transfer of flaps.
