The association of cryptorchidism, functional Sertoli cell tumors, and spermatic cord torsion has been rarely reported in the literature. Two dogs were admitted for bilateral skin alopecia and weight loss. Both animals were cryptorchid and displayed a pendulous preputial sheath, prostate hypertrophy, and increased levels of circulating oestrogen. Transabdominal palpation and ultrasonography revealed the presence of neoplastic retained gonads. During surgery, spermatic cord torsion was also detected in the enlarged neoplastic testes of both dogs. Histologic examination confirmed the presence of Sertoli cell tumors that were primarily responsible for the feminizing syndrome. Complete remission of all symptoms occurred within 3 months after orchiectomy.

PURPOSEMaxillofacial injuries are frequently associated with multiple trauma and can determine functional and aesthetic bad outcomes. The severity of maxillofacial injuries may be considerable and can divert clinicians' attention from other concomitant injuries which is less evident but potentially life-threatening. The aim of this study was to find out the concomitant injuries in patients referred to the Emergency Department (ED) of the University Hospital of Messina (North-East Sicily, Italy) for maxillofacial traumas.

METHODSWe retrospectively evaluated data of 240,833 patients admitted at the ED of the University Hospital of Messina from January 2008 to December 2015 because of maxillofacial injuries leading to hospitalization and surgical treatment. Patients who primarily received treatment care at different institutions, pediatric trauma patients and adult patients who were transferred in accordance with pre-existing agreements in case of paucity of beds were excluded. Finally we included 447 (0.2%) patients over the 8 years. Data were evaluated with emphasis on epidemiology (age, gender, mechanism of trauma), primary survey and abnormalities and pattern of trauma.

RESULTSThe most frequent cause of maxillofacial trauma was road accidents (319 patients, 71.4%), among which motorcycle ones were prevalent. The maxillofacial injured who presented major lesions were 98 patients and minor lesions occurred in 349 patients; 443 (99.1%) patients underwent maxillofacial surgery, immediate or delayed depending on the severity of concomitant injuries (χ = 557.2, p < 0.0001). Five concomitant neglected lesions were found to be associated with severe maxillofacial traumas (χ = 17.13, p < 0.0001 vs minor lesions). All of the neglected lesions occurred in paucisymptomatic patients who showed painless abdomen, no hemodynamic instability, no signs of hematoma of anterior and posterior abdominal wall or other suspicious clinical signs and symptoms.

CONCLUSIONAmong the patients admitted firstly in other surgical wards different from the Maxillofacial Surgery Unit, diagnosis was more difficult, especially for blunt abdominal traumas, in which patients showed only vague and nonspecific symptoms concealing serious and life-threatening injuries. We recommend the routine use of whole body CT scan, when the maxillofacial injuries appear prevalent, mainly in patients affected by maxillofacial major lesions.

Objective: To identify the available evidence on the effects of rapid maxillary expansion (RME) with three-dimensional imaging and provide meta-analytic data from studies assessing the outcomes using computed tomography. Methods: Eleven electronic databases were searched, and prospective case series were selected. Two authors screened all titles and abstracts and assessed full texts of the remaining articles. Seventeen case series were included in the quantitative synthesis. Seven outcomes were investigated: nasal cavity width, maxillary basal bone width, alveolar buccal crest width, alveolar palatal crest width, inter-molar crown width, inter-molar root apex width, and buccopalatal molar inclination. The outcomes were investigated at two-time points: postexpansion (2–6 weeks) and post-retention (4–8 months). Mean differences and 95% confidence intervals were used to summarize and combine the data. Results: All the investigated outcomes showed significant differences postexpansion (maxillary basal bone width, +2.46 mm; nasal cavity width, +1.95 mm; alveolar buccal crest width, +3.90 mm; alveolar palatal crest width, +3.09 mm; intermolar crown width, +5.69 mm; inter-molar root apex width, +2.85 mm; and dental tipping, +3.75°) and post-retention (maxillary basal bone width, +2.21 mm; nasal cavity width, +1.55 mm; alveolar buccal crest width, +3.57 mm; alveolar palatal crest width, +3.32 mm; inter-molar crown width, +5.43 mm; inter-molar root apex width, +4.75 mm; and dental tipping, 2.22°) compared to pre-expansion. Conclusions After RME, skeletal expansion of the nasomaxillary complex was greater in most caudal structures. Maxillary basal bone showed 10% post-retention relapse. During retention period, uprighting of maxillary molars occurred.

A variety of techniques and materials for the rehabilitation and reconstruction of traumatized maxillary ridges prior to dental implants placement have been described in literature. Autogenous bone grafting is considered ideal by many researchers and it still remains the most predictable and documented method. The aim of this report is to underline the effectiveness of using allogeneic bone graft for managing maxillofacial trauma. A case of a 30-year-old male with severely atrophic maxillary ridge as a consequence of complex craniofacial injury is presented here. Augmentation procedure in two stages was performed using allogeneic and autogenous bone grafts in different areas of the osseous defect. Four months after grafting, during the implants placement surgery, samples of both sectors were withdrawn and submitted to histological evaluation. On the examination of the specimens, treated by hematoxylin and eosin staining, the morphology of integrated allogeneic bone grafts was revealed to be similar to the autologous bone. Our clinical experience shows how the allogeneic bone graft presented normal bone tissue architecture and is highly vascularized, and it can be used for reconstruction of severe trauma of the maxilla.

Virtual surgical planning (VSP) has recently been introduced in craniomaxillofacial surgery with the goal of improving efficiency and precision for complex surgical operations. Among many indications, VSP can also be applied for the treatment of congenital and acquired craniofacial defects, including orbital fractures. VSP permits the surgeon to visualize the complex anatomy of craniofacial region, showing the relationship between bone and neurovascular structures. It can be used to design and print using three-dimensional (3D) printing technology and customized surgical models. Additionally, intraoperative navigation may be useful as an aid in performing the surgery. Navigation is useful for both the surgical dissection as well as to confirm the placement of the implant. Navigation has been found to be especially useful for orbit and sinus surgery. The present paper reports a case describing the use of VSP and computerized navigation for the reconstruction of a large orbital floor defect with a custom implant.
