Introduction. The functional results of surgery in terms of facial mobility are key elements in the treatment of patients. Little is actually known about changes in facial mobility following surgical treatment with maxillomandibular advancement (MMA). Objectives. The three-dimensional (3D) methods study of basic facial movements in typical OSAS patients treated with MMA was the topic of the present research. Materials and Methods. Ten patients affected by severe obstructive sleep apnea syndrome (OSAS) were engaged for the study. Their facial surface data was acquired using a 3D laser scanner one week before (T1) and 12 months after (T2) orthognathic surgery. The facial movements were frowning, grimace, smiling, and lip purse. They were described in terms of surface and landmark displacements (mm). The mean landmark displacement was calculated for right and left sides of the face, at T1 and at T2. Results. One year after surgery, facial movements were similar to presurgical registrat...

The aim of the study was to analyze the incidence, characteristics, and correlations between maxillofacial fractures and dental injuries in patients who were treated at a first-level trauma center in a metropolitan center in northwest Italy in the last 11 years. Between January 1, 2001 and December 31, 2011, 2,110 patients with maxillofacial fractures were admitted. Only dentulous patients with complete clinical records who presented with associated dental injuries were included in this study. Data on the age, gender, mechanism of injury, damaged tooth, type of dental injury, site of facial fractures, and concomitant injuries were recorded. On the whole, 267 patients (13.1%), mainly males aged 20-29 years, presented with 759 dental injuries associated with maxillofacial fractures, especially following motor vehicle accidents. The maxillary teeth, most often the anterior elements with decreasing involvement from the incisors to the molars, were the teeth most frequently damaged overa...

A 31-year-old woman presented with a large oro-nasal communication (ONC), loss of vomer and significant nasal cartilage and nose deformity. Physical examination of the patient revealed a typical midline destructive lesion (MDL) with nasal septum and hard/soft palate perforation with a friable granular surface and a large amount of necrotic tissues. Medical history was unremarkable and the patient denied previous local trauma, including surgical procedures or drug assumption. Pathological examination revealed the presence of necrosis and chronic inflammation. MDLs have numerous etiologies. Signs and symptoms of MDLs can be similar and an accurate diagnosis may be elusive. We hereby present detailed clinicopathological findings.

The aim of this study was to assess the incidence and patterns of work-related maxillofacial injuries, identifying worker categories with a high risk of injury. From a systematic computer-assisted database that has continuously recorded patients hospitalized with maxillofacial fractures, only patients with work-related injuries were considered. Occupation, mechanism of injury, and demographic and clinical data were analyzed. Work-related facial injuries represented the fifth most common cause of injury, with a percentage of 6.3 %. Maxillofacial fractures were most often seen in construction workers (37.9 %). The middle third was involved in 67 % of the cases; the mandible was the most frequently injured site. Work-related maxillofacial trauma is rare, but it is often complex and challenging as Facial Injury Severity Scale values show. In agreement with the few published reports, construction workers, together with farm and forestry workers, are at the highest risk of injuries, mainl...

The aim of this study was to evaluate the surgical outcomes using polyetheretherketone (PEEK) patient-specific prostheses produced by computer-aided design and manufacturing for primary and secondary reconstruction in patients with craniofacial defects. The study included 13 patients who underwent reconstruction for craniofacial defects using PEEK patient-specific implants (PSI). Eight patients underwent single-step primary reconstruction using individual custom-made surgical guides and custom-made prostheses during the same surgery; five patients underwent delayed reconstruction. The material used to manufacture the implants was PEEK in 13 cases. All patients underwent esthetic examination, ophthalmological examination, and radiological evaluation during the preoperative and follow-up periods. The operation duration and short- and long-term complications were recorded. The shape and global position of the implants were satisfactory in each case. Fitting of the implant during surgery required extensive adaptation in 1 case and minor in 11 cases. Of 13 implants, 11 adequately restored a morphological complex area with satisfactory cosmetic results. No complications related to the implants were reported. Reconstruction for cranio-facial defects using PEEK computer-aided designed and manufactured implants is a promising new technique that allows for accurate restoration of the complex 3D anatomy of the craniofacial region.

The aim of this study was to analyze the differences in facial soft tissue changes, despite the same extent of upper jaw forward movement, between patients with unilateral cleft lip and palate (uCLP) and those without, after LeFort I osteotomy and secondary rhinoplasty. Twelve patients with maxillary retrognathic dysplasia and nose deformity were divided in 2 groups, A (uCLP) and B (control), and compared on the basis of the same maxillary advancement. Cephalometry and 3D mean facial model of groups A and B were obtained before and after surgery. Linear and angular measurements were calculated. Upper vermilion and alar base remained unchanged in group A but increased in group B. In both groups, symmetry of the nasal base was improved, and an increase of the sagittal projection of the lips was observed. 3D analysis showed that surgical procedures for uCLP can provide a satisfactory aesthetic outcome, but some differences are evident in comparison with the control group.

This study analyzed the outcomes of nongrowing patients with unilateral mandibular hypoplasia treated according to a specific protocol, which combines distraction osteogenesis, orthodontic treatment, and conventional osteotomies. The patients treated were objectively evaluated. Patient's satisfaction was assessed by questionnaire. Surgical changes were analyzed using cephalometry and three-dimensional facial surface data before surgery (T0) and at long-term (T1) follow-up. Four patients were included in this study. The normalization of facial proportion and a high increase in symmetry were evident. Residual defects were documented in the postoperative symmetry of the chin. In the questionnaire, all patients gave favorable responses to their facial changes; for most of the objective parameters, all patients improved. A multistage treatment protocol for the correction of facial deformities in patients with unilateral mandibular hypoplasia is a valid procedure for skeletal and occl...

In several epidemiological studies of maxillofacial trauma, falls were one of the most frequent causes of facial injury. The aim of this study is to analyse the patterns of fall-related maxillofacial injuries based on the height of the fall. Using a systematic computer-assisted database of patients hospitalised with maxillofacial fractures, only those with fall-related injuries were considered. The falls were divided into four groups: falls from slipping, tripping or stumbling (STSF), loss of consciousness (LOCF), stairs (SAF), and height (HF). Data on the age, gender, fracture site, Facial Injury Severity Scale (FISS), facial lacerations, associated lesions, type of treatment, and length of hospital stay were also analysed. This study included 557 patients (338 males, 219 females; average age 51.5 years [range 4 - 99 years]). In the over 60 age group, females were more prevalent in STSF than males. According to aetiology, STSF was the most frequent cause of maxillofacial fractures ...

Orbital trapdoor fractures are pure orbital floor fractures with herniation and entrapment of the orbital contents, leading to restricted eye movement and diplopia. Trapdoor fractures in children have been discussed widely in published reports; however, the treatment policy and outcome remain controversial, although early treatment has been advocated. Our retrospective study analyzed the long-term results of pediatric patients undergoing surgery for trapdoor fractures to determine the outcome in relation to the type of fracture and the timing and technique of intervention. The present study included 24 patients (age range 6 to 16 years) who underwent surgery for trapdoor fractures from 1998 to 2007. The demographic, etiologic, radiologic, and surgical findings, interval between trauma and surgery, surgical techniques, and complications were recorded. Diplopia, ocular motility, dysesthesia, and scar quality were recorded at follow-up. The follow-up duration averaged 36 months. At follow-up, 1 (8.3%) of 12 patients who underwent surgery within 24 hours (urgent treatment) had residual diplopia. In contrast, 3 (37.5%) of 8 patients who underwent surgery 24 to 96 hours (early treatment) and 4 (100%) of 4 who underwent surgery after 96 hours (late treatment) had diplopia. No sensory deficit of the skin or unesthetic eyelid scar was noted. We found a correlation between the outcome and the timing of surgery for trapdoor fractures in the pediatric population. The success rate was significantly better when the fractures were treated within 24 hours of the injury. The results of the present study have strengthened the assertion that trapdoor orbital fractures pose a true surgical emergency.

The aim of this study was to evaluate surgical outcomes using patient-specific prostheses produced by computer-aided design and manufacturing for primary reconstruction in patients with benign cranio-orbital tumors. Polyetheretherketone was used to manufacture the implants. The present study included 3 patients who underwent fronto-orbito-pterional craniotomy using individual custom-made surgical guides. Patient-specific polyetheretherketone prostheses were used for reconstruction during the same surgery. All patients underwent esthetic examination (facial and orbital symmetry, globe projection and position), ophthalmologic examination (diplopia with the Hess-Lancaster test, visual field and acuity), and radiologic evaluations (computed tomography and magnetic resonance imaging) during the preoperative and follow-up periods. Operating time and short- and long-term complications were recorded. The immediate and long-term morphologic results were satisfactory; in particular, ocular globe position and projection were correct. After 25 to 31 months, none of the patients developed implant-related complications, such as infection, extrusion, or malposition. Two-year postoperative computed tomograms and magnetic resonance images showed no recurrences. Single-step resection and reconstruction with computer-aided designed and manufactured implants is a challenging new technique that decreases operative time and morbidity. The implants adequately restore an anatomically complex area with satisfactory cosmetic results.

There is no consensus about the surgical treatment of odontogenic myxoma. The aim of the current study was to present our experience and discuss the surgical management and outcome in 10 patients diagnosed with odontogenic myxoma. A retrospective review of charts of patients who were surgically treated for odontogenic myxoma was performed. Patients were recalled, and eventual recurrences were investigated. Eight lesions were mandibular, whereas 2 were maxillary. In 3 patients, enucleation and curettage was performed. Instead, in the remaining 7 patients, segmental resection and immediate reconstruction were decided. At follow-up, no patient showed recurrence of the lesion. Our protocol is to perform conservative surgery by enucleation and curettage when lesions were smaller than 3 cm, whereas a segmental resection with immediate reconstruction is preferred in patients affected by bigger tumors. Long-term follow-up is required, in particular when conservative surgery is preferred.

This study was designed to analyze the etiology and patterns of soft-tissue facial lacerations associated with maxillofacial fractures and to identify associations between facial lacerations and underlying fractures. Of 1960 patients who had been admitted for maxillofacial fractures between 2001 and 2010, only patients with complete clinical records presenting with facial lacerations were considered for this study. Facial lacerations were classified according to the MCFONTZL system. Of the 1960 patients admitted with maxillofacial fractures, 637 had 836 associated facial lacerations. Motor vehicle accidents and falls were responsible for most injuries to patients with facial lacerations. According to etiology, fractures resulting from work-related accidents more frequently produced associated lacerations.For all causes of injury, more facial lacerations were observed over the "T" area formed by the upper orbit and forehead, nose, upper and lower lips, and chin. Lacerations and maxillofacial fractures were more frequently localized to the middle third of the face, followed by the inferior third.There was a strong association between lacerations and fractures in the chin region, considering both symphyseal and parasymphyseal fractures (direct trauma) and condylar fractures (indirect trauma). An association between facial lacerations and underlying maxillofacial fractures was observed, particularly in the inferior orbital area and over the zygoma, mandible, and chin.
