RESUMEN
Synovial chondromatosis is a benign condition characterised by the presence of small cartilaginous nodules in the joint; its aetiology is unknown. Only a few cases of temporomandibular chondromatosis are described in the literature. In some cases, the synovial chondromatosis can erode the adjacent bone structures, such as the glenoid fossa, middle cranial fossa, and internal carotid canal. In these cases, besides MRI, the gold standard to verify the erosion of the glenoid fossa is a computed tomography scan. The aim of this study is to report the use of MRI with PETRA (pointwise encoding time reduction with radial acquisition) sequences for the diagnosis and follow-up of temporomandibular joint chondromatosis with suspected erosion of the glenoid fossa.
RESUMEN
OBJECTIVES: To assess the skeletal and dental maxillary transverse compensation (yaw) on the cone beam computed tomography (CBCT) three-dimensional reconstructed image of the skull in two groups of patients, both clinically affected by a class III malocclusion with deviation of the lower midline. MATERIALS AND METHODS: An observational retrospective study was designed to analyse differences in two groups of patients, the first one was composed by patients affected by horizontal condylar hyperplasia, the second one by patients affected by dento-skeletal asymmetric class III malocclusion. Each group was composed by 15 patients. Transverse analysis was performed by measuring five landmarks (three bilateral and two uneven) with respect to a mid-sagittal plane; sagittal analysis was performed by measuring the sagittal distance on the mid-sagittal plane between bilateral points. Means were compared through inferential analysis. RESULTS: In the condylar hyperplasia group, all differences between the two sides were not statistically significant, nor for canines' difference (P = .0817), for molars (P = .1105) or for jugular points (.05871). In the class III group, the differences between the two sides were statistically significant for molars (P = .0019) and jugular points (P = .0031) but not for canines (P = .1158). Comparing the two groups, significant differences were found only for incisors' midline deviation (P = .0343) and canine (P = .0177). CONCLUSION: The study of the yaw on CBCT should be integrated into three-dimensional cephalometry and could help in differentiating the various malocclusion patterns.

The aim of this systematic review was to investigate whether the presence of third molars (3Ms) during sagittal split osteotomy of the mandible increases the risk of complications. Searches were conducted using MEDLINE via PubMed, LILACS, Cochrane Central, Scopus, DOSS, and SIGLE via OpenGrey up to December 2020. Fifteen articles were included for evaluation and 14 in the meta-analysis, with a total of 3909 patients and 7651 sagittal split osteotomies (670 complications). Inferior alveolar nerve (IAN) exposure in the proximal segment was the most frequent complication (n = 409), followed by bad splits (n = 151). Meta-analysis revealed no significant increase in the incidence of 3M-related IAN exposure (P = 0.45), post-surgical infections (P = 0.15), osteosynthesis material removal (P = 0.37), or bad splits (P = 0.23). The presence of 3Ms was associated with a reduced risk of nerve disorder (P = 0.05) and favoured bad splits in the lingual plate (P = 0.005). The quality of evidence was very low, mainly due to non-randomized study designs, high risk of bias, inconsistency, and imprecision. This systematic review suggests that the removal of 3Ms before sagittal mandibular osteotomy does not reduce the incidence of complications. Thus, we recommend future better-designed studies with rigorous methodologies and adjustments for confounding factors.

The outbreak of coronavirus disease 2019 (COVID-19) is rapidly changing our habits. To date, April 12, 2020, the virus has reached 209 nations, affecting 1.8 million people and causing more than 110,000 deaths. Maxillofacial surgery represents an example of a specialty that has had to adapt to this outbreak, because of the subspecialties of oncology and traumatology. The aim of this study was to examine the effect of this outbreak on the specialty of maxillofacial surgery and how the current situation is being managed on a worldwide scale. To achieve this goal, the authors developed an anonymous questionnaire which was posted on the internet and also sent to maxillofacial surgeons around the globe using membership lists from various subspecialty associations. The questionnaire asked for information about the COVID-19 situation in the respondent's country and in their workplace, and what changes they were facing in their practices in light of the outbreak. The objective was not only to collect and analyse data, but also to highlight what the specialty is facing and how it is handling the situation, in the hope that this information will be useful as a reference in the future, not only for this specialty, but also for others, should COVID-19 or a similar global threat arise again.

OBJECTIVES: The primary aim of this study was to compare the diagnostic accuracy of transvaginal sonography (TVS) with vs without bowel preparation (BP) in detecting the presence of rectosigmoid endometriosis. Secondary objectives were to compare the diagnostic accuracy of the two techniques in estimating infiltration of the submucosa, length of the largest rectosigmoid nodules, distance of the nodules from the anal verge and presence of multifocal disease. METHODS: This was a prospective study of patients with symptoms of pelvic pain for more than 6 months and/or suspicion of endometriosis referred to our institution between October 2016 and April 2018. Participants underwent a first TVS without BP followed by TVS with BP within a time interval of 1 week to 3 months. The examinations were performed independently and blindly by two sonographers. Only patients who underwent laparoscopy within the 6 months following the second ultrasound examination were included. Ultrasound results using the two techniques were compared with surgical and histological findings. RESULTS: Of the 262 patients included in the study, 118 had rectosigmoid endometriosis confirmed at surgery. There was no significant difference in accuracy between TVS with and that without BP in diagnosing the presence of rectosigmoid endometriosis (93.5% vs 92.3%; P = 0.453). No significant difference was observed in accuracy between TVS with and that without BP in diagnosing submucosal infiltration (88.8% vs 84.6%; P = 0.238) and multifocal disease (97.2% vs 95.2%; P = 0.727) in patients diagnosed sonographically with rectosigmoid endometriosis. The accuracy of TVS with BP was similar to that of TVS without BP in estimating the maximum diameter of the largest nodule (P = 0.644) and the distance between the more caudal rectosigmoid nodule and the anal verge (P = 0.162). CONCLUSION: BP does not improve the diagnostic performance of TVS in detecting rectosigmoid endometriosis and in assessing characteristics of endometriotic nodules. Copyright © 2018 ISUOG.

OBJECTIVES: Several studies have investigated the correlation between endometriosis and adverse pregnancy and perinatal outcomes. However, the role of adenomyosis as a risk factor for adverse perinatal outcome in women with endometriosis has yet to be established. The aim of this study was to explore if fetal and maternal outcomes, in particular the incidence of a small-for-gestational-age (SGA) infant, are different in pregnant women with endometriosis only from in those with the concomitant presence of diffuse or focal adenomyosis. METHODS: This was a retrospective analysis of data collected prospectively during a 3-year period. We included 206 pregnant women with endometriosis: 148 (71.8%) with endometriosis only, 38 (18.4%) with focal adenomyosis and 20 (9.7%) with diffuse adenomyosis. Adenomyosis was diagnosed using ultrasonography and was classified as focal or diffuse. The study included patients who conceived spontaneously or by an assisted reproductive technique. Demographics, ultrasound variables and outcome were compared between women with endometriosis only and those with diffuse and those with focal adenomyosis. Logistic regression analysis was performed to assess the association of variables with SGA at birth in women with diffuse and those with focal adenomyosis. RESULTS: The three groups were similar in demographic characteristics (age, body mass index, mode of conception). Patients with diffuse adenomyosis compared with those with endometriosis only had significantly lower pregnancy-associated plasma protein A (0.61 vs 0.88 multiple of the median, P < 0.001), higher mean uterine artery pulsatility index in the first (2.23 vs 1.67, P < 0.001) and second (1.30 vs 0.94, P < 0.001) trimesters of pregnancy, and higher incidence of SGA (40% vs 10.8%, P < 0.001). No statistically significant differences were found in patients with focal adenomyosis compared with those with endometriosis only. Logistic regression analysis demonstrated that diffuse adenomyosis (odds ratio = 3.744; 95% CI, 1.158-12.099; P = 0.027) was the only independent risk factor for SGA. CONCLUSIONS: The presence of diffuse adenomyosis in pregnant women with endometriosis is strongly associated with delivery of a SGA infant. Women with diffuse adenomyosis should be treated as being at high risk of placental dysfunction, and these pregnancies might therefore need closer monitoring. Copyright © 2017 ISUOG.

In 2008, we presented our security "high-tech" individual extra-light device mask (SHIELD), a protective shield based on the face cast of an injured soccer player that can be customised. It allows a shortened convalescent period, is comfortable, fits well, and allows the patient to continue to play at a professional level in their chosen sport or activity in the shortest time possible. It has been used often in both amateur and professional categories of many sports, and we now present an update.

OBJECTIVE: To compare the accuracy of magnetic resonance enema (MR-e) and rectal water-contrast transvaginal sonography (RWC-TVS) in the diagnosis of rectosigmoid endometriosis. METHODS: This prospective study included 286 patients of reproductive age with clinical suspicion of rectosigmoid endometriosis. Patients underwent MR-e and RWC-TVS before laparoscopic excision of endometriotic lesions. The findings of MR-e and RWC-TVS were compared with surgical and histological results. RESULTS: Of the 286 patients included in the study, 151 (52.8%) had rectosigmoid endometriosis. MR-e and RWC-TVS had similar accuracy in the diagnosis of rectosigmoid endometriosis (P = 0.063). In the diagnosis of rectosigmoid endometriosis with MR-e, the sensitivity was 95.4% (95% CI, 90.7-99.1%), specificity was 97.8% (95% CI, 93.6-99.5%), positive predictive value (PPV) was 98.0% (95% CI, 94.1-99.6%), negative predictive value (NPV) was 95.0% (95% CI, 89.9-97.9%), positive likelihood ratio (LR+) was 42.91 (95% CI, 14.01-131.46) and negative likelihood ratio (LR-) was 0.05 (95% CI, 0.02-0.10). For diagnosis with RWC-TVS, sensitivity was 92.7% (95% CI, 87.3-96.3%), specificity was 97.0% (95% CI, 92.6-99.2%), PPV was 97.2% (95% CI, 93.0-99.2%), NPV was 92.3% (95% CI, 86.6-96.1%), LR+ was 31.29 (95% CI, 11.90-82.25) and LR- was 0.08 (95% CI, 0.04-0.13). MR-e and RWC-TVS underestimated the size of the endometriotic nodules; for both imaging techniques the underestimation was greater for nodules with a diameter ≥ 30 mm. There was no significant difference in the mean intensity of pain experienced by the patients during the two examinations. CONCLUSIONS: RWC-TVS should be the first-line investigation in patients with clinical suspicion of rectosigmoid endometriosis and physicians should be trained in performing this examination. Considering that MR-e is more expensive than RWC-TVS, it should be used only when the findings of RWC-TVS are unclear. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

OBJECTIVES: To compare the performance of computed tomographic colonography (CTC) and rectal water-contrast transvaginal sonography (RWC-TVS) in the diagnosis of rectosigmoid endometriosis, and compare precision in estimating the length of the rectosigmoid nodules and the distance between the nodules and the anal verge. METHODS: This prospective study included 70 patients of reproductive age with clinical suspicion of rectosigmoid endometriosis. Patients underwent RWC-TVS and CTC before laparoscopic excision of endometriotic nodules. The findings of RWC-TVS and CTC were compared with surgical and histological results. RESULTS: Of the 70 patients included in the study, 40 (57.1%) had rectosigmoid endometriosis. CTC and RWC-TVS had similar accuracy in the diagnosis of rectosigmoid endometriosis (P = 0.508) and similar precision in estimating the length of the endometriotic nodules (P = 0.077). CTC was more precise than RWC-TVS in estimating the distance between the rectosigmoid nodule and the anal verge (P < 0.001). The intensity of pain experienced during CTC was higher than that perceived during RWC-TVS (P < 0.001); however, intestinal distension for CTC was well-tolerated in all patients without significant adverse effects. CONCLUSIONS: RWC-TVS and CTC have similar accuracy in the diagnosis of rectosigmoid endometriosis and similar precision in estimating the size of the nodules; however, CTC is more precise than RWC-TVS in estimating the distance between the nodules and the anal verge, yet patients tolerate RWC-TVS better than CTC.

Purpose ofInvestigation: Solid ovarian tumors represent a clinical challenge, in particular in case of young patients who require a fertility sparing treatment. The authors report a case of hypercellular mitotically active ovarian fibrothecoma in a very young woman, successfully treated with a fertility sparing surgery. MATERIALS AND METHODS: A 21-year-old nulliparous woman presented at the present hospital with a 14-cm right ovarian mass, consisting of solid and pseudo-cystic components. There was neither an elevation of tumor markers nor evidence of metastatic disease. A laparotomic right salpingo-oophorectomy was performed. Uterus and left adnexa were preserved. RESULTS: The neoplasm consisted of a prevalent population of spindle-shaped elements and of a minor component of cells with wider cytoplasms, attributable to a thecomatous differentiation. The mitotic activity was focally elevated. Cytological atypia was mild to focally moderate. Clear areas of coagulative necrosis were not observed. At present 48 months after surgery, the patient is alive with no evidence of recurrence. CONCLUSIONS: The authors reported the lesion as a hypercellular and mitotically active fibrothecoma. The uneventful follow-up confirms the low malignant potential of the lesion. Caution is required reporting hypercellular stromal ovarian tu- mors, in order to avoid overdiagnosis and overtreatment, particularly in young patients.

Chemo-radiation represents an effective therapy for carcinoma of the uterine cervix. The endometrium may however receive a consistent dose of mutagenic radiations and patients may have an increased risk of secondary malignancies. Endometrial mixed malignant mullerian tumor (MMMT) is a rare, highly aggressive disease, and neuroendocrine features are even rarer. A 68 years old woman underwent radio-chemotherapy for a squamous cell carcinoma of the cervix. Follow up was uneventful until, eight years after radio-chemotherapy, imaging exams detected a diffuse enlargement of the uterine body. Radical hysterectomy revealed a multiphasic lesion with both sarcomatous and mixed carcinomatous components. The carcinomatous, component presented neuroendocrine histologic and ultrastuctural features and an intense expression of neuroendocrine immunohistochemistry markers. No residual cervical carcinoma was documented (pR0). The patient died of disease after 9 months. Reported cases further demonstrate how the irradiation of the uterus for cervical cancer carries a not negligible risk of developing a second endometrial cancer. The second cancer may develop years after initial therapy and may have aggressive histologic and clinical features. This case underlines the importance for a long follow-up in women having received radio-chemotherapy alone.

PURPOSE OF INVESTIGATION: To propose a multidisciplinary protocol for postmortem disclosure of complex fetal malformations, comparing ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and autopsy in a case of conjoined ischiopagus twins. MATERIALS AND METHODS: A screening second-trimester ultrasound diagnosed ischiopagus twins at 20 gestational weeks in a 31-year-old woman without any previous ultrasound examination. The couple decided for pregnancy termination. The formalin-fixed fetuses underwent full-body CT, MRI, and autopsy. RESULTS: ultrasound accurately diagnosed ischiopagus twins. CT was very accurate in the description of bone components. MRI allowed better visualization of the visceral organs than CT. Only autopsy could disclose the aspect of the two gastrointestinal tracts and the external genitalia. CONCLUSIONS: Prenatal ultrasound represents the standard diagnostic exam for conjoined twins. CT-MRI virtual autopsy (virtopsy) may be an option if the couple refuses to authorize necropsy or may be useful to plan a minimally invasive autopsy preserving the external phenotype.

BACKGROUND: Human papillomavirus 16 infection has been proven to be associated with oropharyngeal squamous cell carcinomas (SCCs) and is probably the main reason of the reported increase in the incidence. The role of high-risk (HR) HPV for carcinogenesis of other sites in the head and neck awaits confirmation. With the aim to evaluate the prevalence of HPV infection and the reliability of different diagnostic tools in SCCs of different sites, 109 consecutive untreated head and neck SCCs were enrolled, and fresh tumour samples collected. METHODS: Human papillomavirus DNA was detected by Digene Hybrid Capture 2 (HC2). Human papillomavirus E6 and E7 mRNA were detected by NucliSENS EasyQ HPVv1. P16 expression was evaluated by immunohistochemistry. RESULTS: In all, 12.84% of cases were infected by HR genotypes and 1.84% by low-risk genotypes. Human papillomavirus 16 accounted for 87% of HR infections. The overall agreement between DNA and RNA detection is 99.1%. Although p16 expression clearly correlates with HPV infection (P=0.0051), the inter-rater agreement is poor (k=0.27). The oropharynx showed the highest HR HPV infection rate (47.6%) and was also the only site in which p16 immunohistochemistry revealed to be a fair, but not excellent, diagnostic assay (κ=0.61). CONCLUSION: The prognostic role of HR HPV infection in oropharyngeal oncology, with its potential clinical applications, underscores the need for a consensus on the most appropriate detection methods. The present results suggest that viral mRNA detection could be the standard for fresh samples, whereas DNA detection could be routinely used in formalin-fixed, paraffin-embedded samples.

INTRODUCTION: Congenital auricular anomalies can be categorized either as malformational or deformational. The first are characterized by a partial absence of the skin or cartilage resulting in a constricted or underdeveloped pinna and require surgical correction. Deformations are characterized by a misshaped but fully developed pinna and are best treated by auricular molding. AIM: Authors want to present their case load in treatment of infants affected by deformational auricolar anomalies and describe their techniques using early splinting for congenital auricular deformities, like prominent ear, lop ear, constricted ear, Stahl's ear. PATIENTS AND METHODS: Between 2009 to 2011, in Maxillo and Oral Surgery Unit, a nonsurgical technique was used to treat 22 ears affected by deformational anomalies in 12 patients soon after birth. Four patients were female. This kind of nonsurgical correction of the deformed auricle was performed on lop ears (n=6), constricted ears (n=8), prominent ears (n= 4), Stahl's ear (n=4). Children more than two months old were also excluded. The mean of treatment time was 5.5 weeks. RESULTS: according to the Authors and the parents 100% of treated auricles improved. Improving at the end of the molding treatment was observed in 18% of the auricles, but recurrence to one year of stopping treatment. There were not complications caused by this procedure. CONCLUSIONS: The nonsurgical molding has the advantage to correct at a very early age a cosmetic abnormality, giving a natural and in the most of the time a satisfactory results, with a prevalence rate of complications of much less than surgical corrections.

BACKGROUND: Indications for treatment of patients with maxillo-mandibular malformations have to be researched both in the severity of anatomical alteration affecting the face and psychological outcomes. Indeed, it has been underlined that patients decide to undergo orthodontic and orthognathic procedure mainly for aesthetical issues. Moreover the early combined functional and surgical treatment improves relationship skills in young adults. Dealing with these "aesthetic" features pre surgical planning presents some additional challenges. Even if orthognatic surgery aims to the correct repositioning of skeletal bases but we must achieve complete patient satisfaction. AIM: The Authors present a new parameter to be considered in the planning of patients who undergo orthognatic procedure being the restitution of the face the patient would have had without any pathologic mechanism with respect of the aesthetic features of the family. MATERIALS AND METHODS: Authors identified a series of parameters discussed by Arnett et al and performed a clinical and photographic evaluation of these parameters, in latero-lateral view, directly on the relatives of the patients. A cephalometric analysis, was performed and a series of parameters has been taken into account. CONCLUSIONS: It is very difficult to standardize universal parameters acceptable and applicable for every single case, considering that patient's awareness of the anatomical defect and post-surgical satisfaction don't relate to the correct cephalometric evaluation and the real aesthetic outcomes.
