Any oral potentially malignant disorders (OPMDs) must be regularly monitored through clinical examination to detect any possible malignant transformation. Conventional intraoral exams, however, can be difficult because these conditions may resemble benign lesions. For this reason, several non-invasive diagnostic technologies have been developed to help the clinician in detecting and distinguishing between cancerous and benign lesions. Epithelial dysplasia can be considered the most important predictor of malignant evolution. Therefore, in this study we aim to evaluate the ability of an optical filter for autofluorescence Glasses for Oral Cancer Curing Light Exposed (GOCCLESIn this retrospective study, medical records, photographs and videos of 25 patients with oral lesions were analyzed. Forty-two biopsy samples in 25 patients with OPMDs and at least one suspicious oral mucosa lesion that were evaluated in white light, autofluorescence with optical filter GOCCLESThe sensitivity and specificity for the autofluorescence evaluation with GOCCLESThe optical filter for autofluorescence (GOCCLES

Statement of problem Dentistry has evolved significantly with the introduction of digital technologies and materials; however, clinical evidence for the performance of the complete digital workflow for single implant–supported posterior crowns is lacking. Purpose The purpose of this cross-sectional retrospective clinical study was to compare the clinical outcomes of 2 types of implant-supported crown used to replace a single missing posterior tooth in a completely digital workflow: transocclusal screw-retained monolithic lithium disilicate crowns versus transocclusal screw-retained monolithic zirconia crowns. Material and methods A total of 38 participants who had been provided with dental implants and transocclusal screw-retained monolithic lithium disilicate or zirconia single crowns were evaluated in the study. Clinical and esthetic outcomes were recorded after a 3-year follow-up. Results Both groups had comparable clinical outcomes with a survival rate of 100%. In the lithium disilicate group, 89% of the participants were free of technical complications, and 95%, in the zirconia group. Only 1 patient experienced minor chipping affecting a lithium disilicate crown. All complications were considered minor and were easily resolved, and none of the participants required replacement of a crown. No biological complications were recorded in either group. Conclusions Within the limitations of this cross-sectional retrospective clinical study, monolithic lithium disilicate and zirconia screw-retained single crowns fabricated using computer-aided design and computer-aided manufacturing (CAD-CAM) and a fully digital workflow were found to be reliable and suitable clinical options for restoring a posterior missing tooth on a dental implant.

Facially malformed patients often present a variable degree of facial imbalance even after basal bone correction, and resolution of the residual hard- and soft-tissue deficiencies and asymmetries of the face are of great importance for achieving a satisfactory post-implant procedure result. The use of polyether ether ketone (PEEK) implants for maxillofacial reconstruction has been documented in the literature, but the number of patients who have received them is limited. The aim of this study was to evaluate the overall volumetric results in patients with facial imbalance after onlay custom implant positioning for mandible and fronto-orbital reconstructions. Analysis was performed by confronting volumes with the use of three-dimensional (3D) photogrammetry. Fifteen patients were eligible for PEEK implant placements, eight for mandibular angle reconstruction, and seven for fronto-orbital reconstruction. Pre- and post-surgical 3D images of each patient’s face were acquired. Facial asymmetry was analyzed by comparing each face with its mirrored copy. Three-dimensional analyses have shown that some degree of volume imbalance was still present in the patients with only 1.32 ± 1.02 mm residual discrepancy after treatment. Results of the study were found to fall within clinically acceptable limits since an asymmetry rate of

What is considered attractive may not fall into the "norm," and it can vary from culture to culture and depending on the historical time, for this reason the standard cephalometric and antropometric references may not be sufficient in these cases.Lately some techniques have arose to popularity that are aimed to changing the frontal and lateral aspect of the facial lower third, such as V-line or the Chin-Wing Osteotomy technique, but no reference system exists at the moment to define to which extent a modification of the lower third falls within what is considered beautiful, and everything is left to the patient's will or to the surgeon's sensitivity.The aim of this article is to study which antropometric value is considered attractive by the most for what concerns the frontal shape of the lower third of the face.Twenty-four female models were enrolled in this study and the angle taken into consideration was the one at the intersection between the 2 lines connecting the cutaneous gonial angle of each side of the face and the most external part of the chin on the same side. Measures were made on pictures in frontal view.Two hundred two random examiners were asked to see the pictures and rate them as attractive or nonattractive.Results were then paired with the angles values.Among the models the higher angle measured was 107.5° (found in 1 individual) while the lower angle was 76° (found in 1 individual), the average measure calculated was 88.3° while the median angle was 89.5°.According to the result the subjects considered more attractive were those with an angle between 84.5 and 91.5 (92 for male examiners).This could be an important starting point for studies who can evaluate attractiveness from a numerical point of view.

The use of anaesthetic drugs in the treatment of oral aphthosis is one of the pharmaceutical possibilities that a doctor can use for the most painful forms. Normally, Lidocaine or Diclofenac is used to treat this disease, but they can be used for a very limited time and so they are of little practical use. In this study, the authors have used Ropivacaine whose pharmaceutical kinetics allows the analgesic effect to be active for 60 to 90 minutes. In our research, we compared 8 groups of patients who have been given 3 principal pharmaceutical products: one group was given an anaesthetic drug, one had a topical medication administered which is often used for the treatment of aphthous lesions, and the last group was given a multivitamin. These pharmaceutical products were used alone and in various possible combinations in the 8 groups. The results of this study are very interesting and show that in all the groups that used anaesthetics there was more satisfaction on the patients’ part because their pain level became more manageable right after the first application of the drug and the patients could carry on with their normal lives.

The use of navigated surgery in the treatment of craniofacial malformations can help obtain optimal results. In this article, the authors will discuss a case of anterior plagiocephaly, corrected with frontorbital bandeau remodeling. Navigation was used during the osteotomy and the reposition phase to ensure the correct positioning of the osteotomy instruments. It was also used to ensure that the bandeau was correctly repositioned in accordance with the surgical plan determined during the virtual simulation phase of the surgery.

In some patients, the resolution of severe maxillary atrophies can be hardly achieved without the use of zygomatic implants. Although many scientific studies have already demonstrated the excellent immediate stability in long term, the use of zygomatic implants is not yet widespread. Among the complications of this technique, the most threatening is the risk of damaging the eyeball or the maxillary nerve.The use of the navigator system as a surgical aid for implant placement allows to control, at any time, the position of the drill in the bone, avoiding any injury to ocular and nervous structures. The authors present a clinical report which shows a patient affected by a very severe form of post-traumatic maxillary atrophy that has been solved through the of zygomatic implants placement using the "Implant Bone Navigation" system. This procedure allows both to cut down the risks on ocular and nervous structures of the maxilla and also to reach excellent rehabilitation results in such severely compromised patients.

Background A cooling system based on polyurethane preshaped masks for postoperative cryotherapy, named Hilotherm, has been recently introduced. The purpose of this study was to evaluate the effectiveness of this equipment in controlling postoperative edema and compare the results with those obtained with a group treated with conventional cryotherapy and a group not treated with cryotherapy. Methods Ninety patients were included in this randomized controlled trial. The 90 patients were divided into 3 groups. Group A was treated with Hilotherm. Group B was treated with conventional cryotherapy. Group C was not treated with cryotherapy. Using a tape measure, we measured for both sides of the face the distances in centimeters between point 0 and external canthus ([alpha]), most lateral point on the ala of the nose ([beta]), commissura labialis ([gamma]), and Pos ([delta]). We performed a Kruskal-Wallis test comparing the average variation of edema on the right and left sides of the face for each facial segment of patients of the 3 groups from time 0 to time 24 hours. Results No cryotherapy is the worst treatment for every segment studied. In anatomic regions defined [beta], [gamma], and [delta], Hilotherm was more effective in containing edema than the ice pack 24 hours after the first measurement. Opposite results were seen on district [alpha], the site not completely enclosed in the mask. Conclusions The substantial difference between different treatments probably consisted in the greater reliability of the Hilotherm system, which is characterized by easy handling, constant temperature control, comfort, and practicality of the masks.

Loss of autofluorescence as an early phenomenon as- sociated with tissue degeneration seems to be promising for the diagnosis of oral cancer. The method seems to make visible early structural and biochemical alterations of the oral mucosa not always evident under direct inspection of the oral cavity. For this reason, the margins of the mucosal lesions usually appear wider compared with direct visualization. Actual extension of the potentially malignant lesions must be precisely perceived to avoid any underestimation of the tumor. In this study, 32 patients at risk for oral cancer underwent autofluorescence test. Of these patients, 12 (group A) experienced potentially malignant diseases. The other 20 patients (group B) were previously operated on for oral cancer. In addition, 13 patients showed loss of autofluorescence (8 patients from group A and 5 patients from group B). Among these 13 patients, 12 were affected with lesions of relevance (in group A, 6 had squamocellular carcinoma and 2 had low-grade dysplasia; in group B, 2 patients had high-grade dysplasia, 2 had low-grade dysplasia, and 1 had an epithelial hypertrophy with inflammatory cells). Preliminary results seem to indicate that autofluorescence is a high-performing test for the individuation of oral cancer in populations at risk (sensibility up to 100% and specificity up to 93% in this study).

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.

This study describes the use of a segmental Le Fort I osteotomy for interpositional autogenous iliac bone grafts in 5 patients with severe unilateral atrophy of the maxilla. Unilateral pterygomaxillary disjunction and osteotomy of the lateral and medial walls of the maxillary sinus were performed. The mucosa of the maxillary sinus was preserved and lifted cranially. It was stabilized with autogenous cancellous bone grafts. One side of the maxilla was gently downfractured until it replaced the original morphology of the alveolar crest. The inter-arch space was therefore reduced to the ideal level for placing implants. Lateral widening of the alveolar crest was obtained with on-lay bone grafts. Segmental osteotomy with bone grafting is a modification of Le Fort I swing osteotomy that has several advantages. The in-lay graft was not resorbed because it was rapidly revascularized and implant placement was delayed. This article presents a surgical technique for the reduction of vertical inter-arch space for the correct positioning of osseointegrated implants.

Introduction. This study aims to investigate the reasons that discourage the patients affected by OSAS to undergo orthognathic surgery and compares the postoperative discomfort of phase I (soft tissue surgery) and phase II (orthognathic surgery) procedures for treatment of OSAS.Material and Methods. A pool of 46 patients affected by OSAS was divided into two groups: “surgery patients” who accepted surgical treatments of their condition and “no surgery patients” who refused surgical procedures. The “surgery patients” group was further subdivided into two arms: patients who accepted phase I procedures (IP) and those who accepted phase II (IIP). To better understand the motivations behind the refusal of II phase procedures, we asked the patients belonging to both the IP group and “no surgery” group to indicate the main reason that influenced their decision to avoid II phase procedures. We also monitored and compared five parameters of postoperative discomfort: pain, painkiller assumption, length of hospitalization, foreign body sensation, and diet assumption following IP and IIP procedures.Results. The main reason to avoid IIP procedures was the concern of a more severe postoperative discomfort. Comparison of the postoperative discomfort following IP versus IIP procedures showed that the former scored worse in 4 out of 5 parameters analyzed.Conclusion. IIP procedures produce less postoperative discomfort. IIP procedures, namely, orthognathic surgery, should be the first choice intervention in patients affected by OSAS and dentoskeletal malformation.

Introduction. Inferior alveolar nerve transposition (IANT) is a surgical technique used in implantoprosthetic rehabilitation of the atrophic lower jaw which has not been well embraced because of the high risk of damage to the inferior alveolar nerve (IAN). There are cases in which this method is essential to obtain good morphologic and functional rebalancing of the jaw. In this paper, the authors present their experience with IANT, analyzing the various situations in which IANT is the only surgical preprosthetic option.Methods. Between 2003 and 2011, 35 patients underwent surgical IANT at our center. Thermal and physical sensitivity were evaluated in each patient during follow-up. The follow-up ranged from 14 to 101 months.Results and Conclusion. Based on our experience, absolute indications of IANT are as follows: (1) class IV, V, or VI of Cawood and Howell with extrusion of the antagonist tooth and reduced prosthetic free space; (2) class V or VI of Cawood and Howell with presence of interforaminal teeth; (3) class V or VI of Cawood and Howell if patient desires fast implantoprosthetic rehabilitation with predictable outcomes; (4) class VI of Cawood and Howell when mandibular height increase with inlay grafts is advisable.

The desmoplastic ameloblastoma (DA) is a rare variant of the conventional ameloblastoma. It accounts for only 4% to 13% of all ameloblastomas. In this article, we describe the case of a young child affected by a giant neglected DA of the jaw. Preoperative biopsy demonstrated the extremely rare osteoplastic variant of DA. The patient was submitted to segmental mandibulectomy and immediate reconstruction with a free fibula osseous flap. The postoperative period was uneventful. The patient was very satisfied with the functional and aesthetic results of the procedure. In case of such rare variants of ameloblastoma, it is mandatory to preoperatively recognize them to allow the adequate treatment modality to be provided.

Background Obstructive sleep apnea syndrome (OSAS) is often found in children affected by congenital or acquired craniomaxillomandibular malformations. This disease carries different levels of risk, ranging from attention problems at school to growth problems and serious disorders, such as cor pulmonale or sudden infant death. The examination that is most commonly used to evaluate the severity of OSAS is polysomnography, and the therapeutic course is often determined by the disease state. Considering the discrepancy between clinical history and polysomnographic findings, we felt the need to identify an instrument for evaluating OSA to be used as a support for polysomnography. Materials and Methods This study was carried out on pediatric patients affected by congenital or acquired craniomaxillofacial malformations. We selected 34 pediatric patients, including 15 boys and 19 girls, aged between 1 and 16 years, with a mean age of 7.3 years. The study consisted of individuation of common clinical history data obtained from each patient and associating those data with the level of OSA severity identified by polysomnography. We were able to isolate certain symptoms and signs that can be predictive of OSA from research in the literature and our clinical experience with pediatric patients. In the clinic, we have found that the clinical history, given by the parents, often differs significantly from the instrumental findings obtained with polysomnography. From the previously expressed considerations and comparison of clinical history data and questionnaires, we have extracted the most significant questions for our questionnaire, which are present in the literature but formulated for adults. Results and Conclusions The obstructive airway child test was found to be a very efficient method to evaluate and diagnose OSA. In all patients, it consistently revealed the pathology and never underestimated OSA severity. The examination focuses on clinical signs and symptoms because, in our opinion, clinical history, reported by the parents, can be more accurate than any instrumental examination.

In this article, we describe an alternative procedure to restore the retrobulbar volume in enophthalmic patients. We report the case of a patient with a late enophthalmos we submitted to retrobulbar lipofilling to correct the defect. The preoperative assessment and the surgical technique are described in detail. The volume of fat injected was 3.2 mL, with a satisfying increase in exophthalmometry measurements. The procedure was well tolerated without complications. Retrobulbar lipofilling for enophthalmos appears to be a safe alternative technique for orbital volume enhancement. It avoids the use of alloplastic materials and allows to obtain good cosmetic results with an easy technique and minimal donor-site morbidity.

Nasal deviation plays an important role in plagiocephaly nosography, and it is frequent in plagiocephaly and objectivable both in early treated patients and in those patients who did not undergo any surgical correction.The group analyzed consisted of 12 patients affected by anterior synostotic plagiocephaly. All of them had reached the end of growth. A morphological analysis was made by using anthropometry. All patients were asked to undergo computed tomography, and all the scans were then reconstructed into three-dimensional models using a dedicated software. We made two-dimensional assessments on coronal and axial slices, and three-dimensional reconstruction was used to evaluate the volumetry of ethmoidal cells.From anthropometry, we realized that, in all patients, not only that the tip of the nose is deviated to the not affected side but also that the root itself does not lie on the midline and it is tilted to the synostotic side. Analysis of the computed tomographic scan results shows that the ethmoid bone, as much as the vomer and the upper maxilla, is deeply involved in these nasal abnormalities, presenting a deviated position and an altered development.We concluded that nasal morphology in plagiocephaly is strictly related to basicranium dysmorphism.

The advent of computed tomography (CT) provided a useful instrument for diagnosis and surgical treatment of patients with craniofacial malformations. The development of software for three-dimensional graphic simulation applied to CT scan has made possible the three-dimensional computerized analysis, surgical planning, and simulation. This kind of analysis is particularly useful in case of complex facial malformations, making reliable a surgical treatment in 1 step. The purpose of this report was to present the diagnosis and treatment planning on a patient with hemimandibular hyperplasia by three-dimensional cephalometric analysis.A 20-year-old young woman who presented with hemimandibular hyperplasia was investigated with CT scan and plaster cast mounted on an articulator; a two-dimensional manual and computerized cephalometric analysis was also developed on frontal and lateral cephalograms. Images in DICOM format were processed on a PC by means of commercial software, thus obtaining the three-dimensional reconstruction of the skeletal structures.Three-dimensional CT permits to program skeletal corrections and to foresee surgical outcomes with adequate realism. Surgical planning based on three-dimensional CT makes it easy and reliable to achieve the correction of the malformation in a single surgical intervention.The virtual three-dimensional CT model, a versatile diagnostic aid, has proven to be effective in the exact reproduction of bone and soft tissue anatomy, thus helping in the diagnosis, surgical planning, and simulations. Three-dimensional analysis is particularly indicated in case of complex asymmetric malformations, in which the more accurate reproduction of the individual anatomy can be very useful in implementing surgical results.

The correction of many craniofacial malformations requires the improvement and stabilization of the midface area. In this article, we present a simple surgical technique for improving and correcting the orbitozygomatic area. This technique is called zygomatic sagittal split osteotomy (ZSSO).Between September 2003 and June 2008, we performed ZSSO on 12 patients. The technique is described in the article. We performed a clinical evaluation of the technique using the following criteria: postsurgical complications, loss of stability, and sagittal prominence. In addition, a radiologic evaluation was performed on axial computed tomographic images. We considered a 1-year follow-up.We performed 15 ZSSO procedures. No evidence of postsurgical complications, loss of stability, or sagittal prominence was reported during the 1-year follow-up.Zygomatic sagittal split osteotomy is a simple surgical technique to be used in the correction and stabilization of the midface area. It can be performed without using graft or osteodistraction device.

Extensive resorption of the mandible increases the interarch space and rehabilitation with traditional dentures is often unsatisfactory due to the superficialization of intraoral muscles. A study of 19 patients who underwent augmentation of an atrophic mandible using a bilateral two-step osteotomy and interpositional bone graft technique is presented. Three horizontal bone cuts (one in the intraforamina and two in the molar region) were made and jointed together by two short vertical bone cuts mesialy to the mental nerve. The cranial fragment was lifted and the iliac bone graft was interposed recreating the correct intermaxillary relationship. A broad vascular pedicle was maintained during surgery, ensuring nutrition from the lingual side, essential to reduce resorption of the bone graft and cranial fragment. 141 Biomet 3i Osseotite((R)) implants were placed. Patients were rehabilitated with a full-arch implant-supported fixed prosthesis or an implant-supported overdenture. This clinical study describes the resorption process over a 4 year follow-up. 3 of 19 suffered from persistent neurosensitive disturbances. In conclusion, bilateral two-step osteotomy in association with interpositional bone graft is a reliable surgical means to recreate the anatomical morphology of the mandible.

In mandibular reconstruction with bone grafts, the functional and aesthetic outcomes are clearly influenced by reconstructive techniques. Vascularized free fibular flaps are considered the most suitable choice for mandible reconstruction because of their good aesthetic and functional outcomes. Several techniques have been described in literature. According to various authors, shaping of the fibular graft can be performed by means of computer-aided design/computer-aided modeling procedures for the evaluation of the presurgery anatomy and three-dimensional models of fibula graft. However, these models are expensive, require a strict realization of the programmed intervention, and are not easily adaptable to a surgical treatment different from the planned one. We report our experience on a technique for mandibular reconstruction using a free fibular flap, obtained by modeling a template on the resected mandible. Our operative technique consists of 5 steps: preplating, resection, template modeling, contouring of the fibula, and fixing the flap on the mandible.Template modeling is performed to record the length of the resected bone, the mandibular curvature on the 3 space planes, and the width of the basal bone. On the basis of the template, the fibula flap was modeled while still attached to the pedicle. The plates, positioned at the level of the fibular osteotomies, were preformed to make the fibula precisely fit in the template. Once the fibula was shaped, mandibular reconstruction was completed by positioning the fibula graft on the mandibular stumps. Bone graft modeling by means of template is a rapid, safe, and flexible method to reconstruct the mandible.

Evaluation of the relapse in patients with craniofacial malformation who underwent craniofacial advancement surgery is very difficult, and data are often unreliable. This is because common skeletal landmarks move from their original position, making standard cephalometries completely useless. To solve this problem, some authors proposed evaluations based on 2- and 3-dimensional computed tomographies, but the biologic risk and the economic outcome do not consent to repeat this kind of examination too often. In this paper, the authors propose a new cephalometric model based on the evaluation of facial skeletal landmarks on the BaS axis. This method, named BaS analysis, might be useful in evaluating improvements of the splanchnocranium in patients who underwent craniofacial advancement.

Limitations in oral opening may be due either to intra-articular or extra-articular ankylosis (pseudoankylosis). The principal means of therapy usually consist of 2 steps: surgical removal of the ankylotic block and immediate functional rehabilitation. In the postoperative period, however, immediate and adequate functional rehabilitation is not always possible because of pain and swelling of the temporomandibular joint, resulting in a very high risk of relapse. To prevent this, the authors introduce a third phase between the 2 already mentioned (surgery and functional therapy) in which the oral opening obtained with surgery is held in place while clinical conditions (pain and swelling) are allowed to stabilize before initiating intensive physiotherapy. Through the discussion of 18 clinical cases (8 of which were treated in the traditional way), the authors report on the intermediate treatment phase introduced by them between the surgical stage and the rehabilitation. Immediately after the operation, a handmade wedge, that is, a bite block of suitable size, is placed between the dental arches for a period of about 3 weeks, while appropriate pharmacological therapy was administered. The results showed an improvement of the mandibular movements both in opening and laterally, on the right and left sides, in patients treated with the new protocol. The proposed protocol holds the opening obtained with surgery until the clinical conditions make it possible to initiate intensive physiotherapy. In this way, the authors obtained better results in both recovery and in mandibular movements.

The purpose of this study was to compare a computed tomographic (CT) three-dimensional analysis with a model analysis to use it as diagnostic aid for the evaluation of occlusal plane tilting in facial asymmetry. Ten patients with facial asymmetry underwent CT three-dimensional examination, plaster cast analysis, and two-dimensional cephalometric analysis. The distance between a reference plane to the upper first molar and upper canine was measured on three-dimensional CT, on models, and on cephalograms to assess occlusal plane tilting. Measurements taken on three-dimensional CT were compared with those taken on articulator and cephalograms, and the level of discordance between the different analyses was evaluated. Quantitative data on the occlusal tilting are similar, but three-dimensional CT gives a better representation of anatomy, thus reducing interpretative problems about altered individual anatomy. Three-dimensional CT seems to be so helpful in detecting individual anatomical variations that it can be adopted in the diagnosis for severe craniofacial asymmetry.

A rare case of aneurysmal bone cyst (ABC) located in the mandibular condyle in a 10-year-old boy is presented. The patient came to our attention for a sudden swelling in the right temporomandibular region, the mouth opening was not reduced. A rapid growing mass, depicting soft tissue invasion, in the right condyle of the mandible was found. Clinically and radiographically it resembled to a malignant lesion. The surgical excision of the mandibular condyle allowed a complete removal of the lesion. The histological examination revealed a pseudocystic expanding osteolytic lesion containing blood-filled space separated by connective tissue and many osteoclastic giant cells, which was a conventional vascular ABC. The ABC is an infrequent bone lesion which can only be found very rarely at the craniofacial skeleton. There have been described about 160 cases of ABC originated in the molar region or in upper maxilla and even more rare is the location of this cyst in the mandibular condyle. Only 6 cases were reported in the literature to date. A complete surgical resection of this osteolytic lesion is the treatment of choice considering its high recurrence rate. The condyle was not replaced with any graft. Therefore a functional device was used after surgery to overcome the lack of the condyle and to stimulate the growth of the ramus.

The purpose of this study was to evaluate if Frankfort plane (FH) and plane passing through the lateral semicircular canals (LS) can be used as reference planes in three-dimensional analysis.Ten patients with facial asymmetry underwent a three-dimensional computed tomography. Computed tomographic images were processed by means of a commercial software and a personal computer to obtain a three-dimensional virtual craniofacial model. The average Frankfort plane and the plane passing through the LS were identified. The distance from the above-mentioned planes to the first upper molar and upper canine cusp was measured.It was not possible to detect an FH plane in any of the patients. Right FH, left FH, average FH, and LS plane were traced. The discrepancies among reference planes were significant in cases with severe asymmetry. A minimal discrepancy was noticed in patients with light asymmetry.In patients with severe asymmetry, the LS plane results in steady, reproducible, detectable, and closer to the patient's anatomy, representing a valid reference plane for three-dimensional computed tomography analysis.

Patients submitted to surgical advancement of the upper and middle facial third might have a relapse of the skeletal retraction after the removal of the distractor devices. Clinical signs related to this process are usually represented by exophthalmos, Obstructive sleep apnea syndrome (OSAS) or prognathism; however, the analytic definition of the relapse is very difficult , conventional cephalometric methods being influenced by the spatial movement of “N” (nasion) or “Or” (orbital) points. The authors present a new cephalometric technique that could be used as a more objective mean of follow-up evaluation of patients undergoing craniofacial advancement. The cephalometric analysis proposed is based on angles, lines, areas and distances between BaS (Basion-Sella) axis and other craniofacial landmark points. We have defined this cephalometric technique as “BaS Analysis”. The “BaS analysis” is not influenced by splanchnocranium movements in the space; for this reason, it can be considered a useful method for cephalometric analysis in the follow-up of patients with craniofacial malformations.

The authors of this study propose a new informed consent form for orthognathic surgery. In a previous study from 2004, a careful review of the international literature and clinical practice suggested the feasibility of dividing the informed consent form into 2 parts, one describing diagnostic procedures and therapeutic/surgical times, and another describing possible problems. During these 4 years, we noticed that this model has 2 setbacks. We replaced point 2, "temporomandibular joint disorders," with "postoperative temporomandibular joint derangement," so that the surgeon is now supposed to inform the patient on the possibility of condylar dislocations, condylar sag, and clockwise/anticlockwise rotations of occlusal surface after surgery. We also changed point 5, "tooth and periodontal disease," in "tooth damage, avulsion, and periodontal disease" because we believe patients should be informed better on the risk of injuries to the dental elements such as fractures, luxations, or avulsions, especially to incisors. In the opinion of the authors, this new informed consent form allows the patient to know the risks related to the orthodontic/surgical therapy better, thus preserving the surgeons from the civil risk and penalties of omission.

The aim of the study was to describe a new and effective method for reconstructing small- and medium-sized oronasal communications in cases of deficient blood supply of oronasal mucosa.A male patient, aged 45, was presented with a hard palate defect due to chronic cocaine inhalation. The defect was corrected using bilateral Bichat bulla adipose flap and a Le Fort I osteotomy. The surgical technique was described, together with its advantages. Surgery lasted 2 hours. The reconstructive technique had been easy to execute. Six months after the surgery, the defect has been corrected without complications.Le Fort I osteotomy and the use of a bilateral Bichat bulla adipose flap is an effective technique to correct small- and medium-sized palatal defects not solvable with simple oral mucosa flaps. The technique is easy to execute and it showed a high efficacy with minimal impact on the patient's esthetic appearance.

The metastases to the TMJ from a primary lung tumour is a very rare occurrence. This case is unusual in several aspects, as the non-reducible dislocation of the TMJ was the first clinical manifestation of the tumour. CT staging showed that this secondary tumour in the condyle was the only bone metastasis.

Objective: Surgical therapy to improve the symptoms and the lesions in osteonecrosis (ON) of the jaws in patients in therapy with bisphosphonates. Design: to evaluate the patient's therapeutic protocols, performance status, and factors promoting ON to prevent surgical failure. Materials and Methods: 18 patients affected by osteonecrotic lesions of the jaws associated to BF, were treated by surgery. Results: The results were recorded after 6 months. All the patients showed improvement of symptoms, in particular the pain. In addition, all the patients referred to a sensation of fresh and clean mouth, the disappearance of fetor ex ore, and a healthy mouth. Conclusions: The management and the resolution of BF osteonecrotic lesions is arguable and complex because in most cases, the patients are affected by oncologic disease when the better approach is prevention, but when the ON lesion is clear, surgery can improve the symptoms and in some cases, it can be resolute. To prevent surgical failure, it can be useful to evaluate the patient's therapeutic protocols, performance status, and factors promoting ON.

Aim The authors’ propose to combine the reverse pull headgear with a Delaire type face mask and a maxillary corticotomy to treat a Class III non-growing patient with maxillary retrusion. The aim of this report is to present two cases in which this treatment strategy was successful. Background Several studies suggest the majority of Class III dento-skeletal malocclusions have components of maxillary retrusion. Early treatment of these patients with maxillary protraction devices have shown promising results. Facemask therapy has some important limits. Most important is the optimal timing of treatment between the ages of six to ten years. Closure of the maxillary suture occurs as a child ages which results in an increase of maxillary resistance to protraction. Report A proposed therapy carried out in orthodontic and surgical phases was used in the treatment of two young patients. They were both beyond the optimal age range for the application of the orthopedic device (a girl 15 years old and a boy 16 years old), however, they had not reached the necessary skeletal maturity for orthognathic surgery. Summary The described technique has the advantage of being quick and easy to perform with a low surgical risk yielding satisfactory results after 15-20 days of therapy instead of the six to nine months associated with traditional procedures.

Many assessments of craniofacial malformations are generally undertaken to assist in surgical intervention including physical examination, cephalometric radiographs in anteroposterior and lateral views, stereolithographic models, and anthropometric measurements integrated with three-dimensional computed tomography (3-D CT) reconstructions to quantify skeletal deformities. In the present report, the use of 3-D Malformation Analysis, a three-dimensional methodology for planning craniofacial operative procedures, is presented. In addition to cephalometric and anthropometric databases, the measurements from 3-D surface reconstructions from CT were used intraoperatively to establish the correct position of skeletal segments.

Lack of sufficient bone to place an implant at the functionally and aesthetically most appropriate position is a common problem, especially in the upper anterior jaw. A surgical technique is proposed to augment the alveolar ridge for vertical and horizontal defects through a localized alveolar osteotomy and interpositional bone graft. Three bone cuts (two vertical and one horizontal) are made in the alveolar bone. This portion of bone is carefully down-fractured. The gap between this bone box and the alveolar bone is filled with an interpositional bone graft. An on-lay bone graft is placed in the buccal side of the defect and fixed with titanium osteosynthesis screws. The aim of this surgical technique is to achieve bone graft healing in a short period of time. The broad vascular pedicle on the palatal side is maintained to ensure a nutritional supply for the down-fractured bone and interposed bone graft. The on-lay bone graft augments the palatal-buccal dimension and the interposed graft guarantees vertical augmentation.

In this study, the authors propose an informed consent form for orthognathic surgery. A careful review of the international literature and clinical practice suggested the feasibility of dividing the informed consent form into two parts. In first part, the diagnostic procedures and the therapeutic and surgical times are described. The patient must sign it as soon he or she accepts the orthodontic/surgical therapy proposed. The second part describes the possible problems and difficulties of the procedure, and it must be read by the patient before starting the therapy. In the opinion of the authors, this informed consent form allows the patient to know the risks related to the orthodontic/surgical therapy, thus preserving the surgeons from the civil risk and penalties of omission.

Fanconi Anemia is a rare autosomal recessive disorder characterized by various congenital malformations, progressive bone marrow failure at a very young age and of solid tumors development. The authors present a rare case of a squamous cell carcinoma of the hard palate in a Fanconi Anaemia patient. The atypical clinical manifestation rendered the diagnosis more difficult. This case, for age of appearance, sex and localization, is unique in international literature. We recommend a quarterly follow up of the oral-rhino-pharynx complex in FA patients and to consider as carcinomas, all oral lesions that last more than two weeks.
