RESUMEN
The diagnostic criteria for silent sinus syndrome (SSS) are still controversial, especially for the post-traumatic/surgery cases that are, nowadays, excluded from the diagnosis of SSS because lacking of spontaneously. We present a systematic review of the last 10 years and our case series of SSS associated to previous trauma/surgery, proposing a new interpretation of SSS. In this work, following the PRISMA guide lines for systematic reviews, we collected 86 articles published on PubMed, Cochrane Library and Medline Plus since 2013 to 2023 about SSS. We divided them in six groups forming the structure of the review: (1) epidemiology, (2) clinical presentation, (3) imaging, (4) etiopathogenesis, (5) sss and craniofacial trauma and (6) treatment. We reported two explicative clinical cases: two men of 34 and 37 years old, involved in motorcycle accident in 2020 and 2014, respectively, and underwent surgery. They came back in 2023 referring diplopia documented by Hess-Lancaster test. CT-scan reported two clear cases of SSS. Basing on what is reported in literature, and basing on our experience, the post-traumatic/surgery SSS are more frequent than the idiopathic ones. Our proposal is to considered them as two individual entities. We propose to adopt the name of Post-traumatic sinus syndrome, or CDR syndrome (Catalfamo-De Rinaldis), for all cases that respect four specific diagnostic criteria reported into the text.
RESUMEN
PURPOSE: The objective of this multicenter study was to examine the differences in maxillo-facial fractures epidemiology across the various phases of the SARS-CoV-2 pandemic. METHODS: This is a retrospective study on patients who underwent surgery for facial bone fractures in 18 maxillo-facial surgery departments in Italy, spanning from June 23, 2019, to February 23, 2022. Based on the admission date, the data were classified into four chronological periods reflecting distinct periods of restrictions in Italy: pre-pandemic, first wave, partial restrictions, and post-pandemic. Epidemiological differences across the groups were analysed. RESULTS: The study included 2938 patients. A statistically significant difference in hospitalization causes was detected between the pre-pandemic and first wave groups (p = 0.005) and between the pre-pandemic and partial restriction groups (p = 0.002). The differences between the pre- and post-pandemic groups were instead not significant (p = 0.106). Compared to the pre-pandemic period, the number of patients of African origin was significantly higher during the first wave and the post-pandemic period. No statistically significant differences were found across the periods concerning gender, age, fracture type, treatment approach, and hospital stay duration CONCLUSIONS: The COVID-19 pandemic brought about significant changes in fracture epidemiology, influenced by the restrictive measures enforced by the government in Italy. Upon the pandemic's conclusion, the fracture epidemiology returned to the patterns observed in the pre-pandemic period.
RESUMEN
Central giant cell reparative granuloma (CGCRG) of the jaw is a neoformation localized in the mandible or in the maxillary bone and characterized by fibrous tissue, osteoclast-like giant cells and reactive bone formation. The CGCRG is a less frequent benign tumor but sometimes it is characterized by an aggressive behavior with a very rapid growth. It affects the young adults mainly and the children occasionally. Nowadays no medication therapy is approved for CGCRG in pediatric cases. We present a case of an aggressive form of a mandibular CGCRG in a 5-year child with Arnold-Chiari syndrome. This case is unique for the use of bisphosphonates (BPs) as neoadjuvant therapy in pediatrics. The therapy were administrated with the purpose of arresting the rapid growth of the tumor in order to avoid a demolitive surgery to the young patient. The child was without symptoms and presented an unusual swelling in the left mandible developed in a few weeks. The lesion was diagnosed by a CT scan and it was confirmed by a biopsy performed for histopathological assessment a few days later. The drug therapy consisted of seven cycles iv of Zoledronate associated to Calcium Gluconate. The child was closely observed through clinical and serological evaluations during the following months. About five months after the last cycle of BPs the child underwent CT scan and a conservative surgical treatment, consisted in a deep curettage, was programmed. Seven months after surgery the aesthetic profile of the patient improved and CT scan reported a significant calcic neoapposition in the area of the previous bone lesion. After more than one year from surgery, no relapse was observed. This case report demonstrates that BPs can be used safely in pediatric patients with CGCRG. Especially BPs could have a role as neoadjuvant therapy: If administrated before surgical treatment BPs avoid the necessity of resective surgery and reduce the risk of recurrence in pediatric CGCRG after conservative curettage.
RESUMEN
Styloid Jugular Nutcracker (SJN, also known as Eagle Jugular Syndrome EJS) derives from a jugular stenosis caused by an abnormal styloid process, compressing the vessel in its superior portion (J3) against the C1 anterior arch. It could be considered a venous vascular variant of Eagle Syndrome (ES). Main clinical features of this ES variant are headache, pulsatile tinnitus and dizziness, possibly related to venous hypertension and impaired cerebral parenchyma drainage. In our opinion, conceptually, it is not the absolute length of the styloid bone that defines its abnormality, but its spatial direction. An elongated bone pointing outward far away from the midline could not compress the vein; vice versa, a short styloid process tightly adherent to the cervical spine could be pathological. To prove this hypothesis, we developed a semi-automatic software that processes CT-Angio images, giving quantitative information about distance and direction of the styloid process in three-dimensional space. We compared eight patients with SJN to a sample of healthy subjects homogeneous for sex and age. Our results suggest that SJN patients have a more vertically directed styloid, and this feature is more important than the absolute distance between the two bony structures. More studies are needed to expand our sample, including patients with the classic and carotid variants of Eagle Syndrome.
RESUMEN
Capsaicin is a chili peppers extract, genus Capsicum, commonly used as a food spice. Since ancient times, Capsaicin has been used as a "homeopathic remedy" for treating a wild range of pathological conditions but without any scientific knowledge about its action. Several studies have demonstrated its potentiality in cardiovascular, nephrological, nutritional, and other medical fields. Capsaicin exerts its actions thanks to the bond with transient receptor potential vanilloid subtype 1 (TRPV1). TRPV1 is a nociceptive receptor, and its activation starts with a neurosensitive impulse, responsible for a burning pain sensation. However, constant local application of Capsaicin desensitized neuronal cells and leads to relief from neuropathic pain. In this review, we analyze the potential adjuvant role of Capsaicin in the treatment of different pathological conditions either in internal medicine or dentistry. Moreover, we present our experience in five patients affected by oro-facial pain consequent to post-traumatic trigeminal neuropathy, not responsive to any remedy, and successfully treated with topical application of Capsaicin. The topical application of Capsaicin is safe, effective, and quite tolerated by patients. For these reasons, in addition to the already-proven beneficial actions in the internal field, it represents a promising method for the treatment of neuropathic oral diseases.

Assessing maximum voluntary bite force is important to characterize the functional state of the masticatory system. Due to several factors affecting the estimation of the maximum bite force, a unique solution combining desirable features such as reliability, accuracy, precision, usability, and comfort is not available. The aim of the present study was to develop a low-cost bite force measurement device allowing for subject-specific customization, comfortable bite force expression, and reliable force estimation over time. The device was realized using an inexpensive load cell, two 3D printed ergonomic forks hosting reusable subject-specific silicone molds, a read-out system based on a low-cost microcontroller, and a wireless link to a personal computer. A simple model was used to estimate bite force taking into account individual morphology and device placement in the mouth. Measurement reliability, accuracy, and precision were assessed on a calibration dataset. A validation procedure on healthy participants was performed to assess the repeatability of the measurements over multiple repetitions and sessions. A 2% precision and 2% accuracy were achieved on measurements of forces in the physiological range of adult bite forces. Multiple recordings on healthy participants demonstrated good repeatability (coefficient of variation 11%) with no significant effect of repetition and session. The novel device provides an affordable and reliable solution for assessing maximum bite force that can be easily used to perform clinical evaluations in single sessions or in longitudinal studies.
RESUMEN
The frontal sinus is one the most complex of the paranasal sinuses, its proximity to the cranial vault and the orbit cause that frontal sinus pathologies can progress to involve these structures and lead to significant morbidity, or even death. Surgical management of the frontal sinus is technically challenging, the most commonly used surgical approaches are coronal, butterfly, gullwing and suprabrow. The purpose of this article is to propose the C-S approach, an interesting alternative to the gullwing approach for the managing of median and paramedian frontal sinus lesions or isolated displaced fractures of the anterior wall. The main advantage of this technique is represented by the fact that it follows the new tension lines described in the literature, a curved vertical line that follows the glabellar frown.
RESUMEN
Transoral endoscopic thyroidectomy by vestibular approach (TOETVA) represents an innovative and scarless technique for thyroid surgery. The procedure is conducted via a three-port technique at the oral vestibule using a 10mm port for the 30° endoscope and two additional 5mm ports for the dissecting and coagulating instruments. Patients meeting the following criteria can be considered as candidates for TOETVA: (a) an ultrasonographically (US) estimated thyroid diameter =10cm; (b) US-estimated gland volume =45mL; (c) nodule size =50mm; (d) presence of a benign tumor, such as a thyroid cyst or a single- or multinodular goiter; (e) Bethesda 3 and/or 4 categories, and (f) papillary microcar-cinoma without the evidence of metastasis. Beyond the classic complications of thyroid surgery, namely cervical hematoma, recurrent laryngeal nerve injury and hypoparathyroidism, novel consequences can occur as mental nerve (MN) injury. In this paper, leading experts in the field report on their current clinical experience with the TOETVA approach for thyroid gland surgery, with emphasis given to tips and tricks to avoid and manage MN injury.

Radiotherapy is essential for achieving and maintaining local control in head and neck rhabdomyosarcoma patients. However, radiotherapy may cause outgrowth disturbances of facial bone and soft tissue, resulting in facial asymmetry.Several studies have shown that the management of irradiated bones still remains challenging. The possibility of obtaining functional and aesthetic results when managing facial deformities due to radiation therapy with distraction osteogenesis combined with free flaps reconstruction is not common and not well documented in recent literature.In this report, we present the long-term results of distraction osteogenesis and soft tissue reconstruction via microvascular free flap to correct the facial hypoplasia of a young patient who underwent radiation therapy for rhabdomyosarcoma.This is the first presentation of 26 years long-term results in a patient who also underwent free flaps reconstruction as ancillary surgery for esthetic good results.

The aim of this study is to analyze the clinical outcome and the change in oral-health-related quality of life (QoL) of osteoporotic patients affected by medication-related osteonecrosis of the jaws (MRONJ). Forty-one patients, consecutively treated for a 10-year period, were retrospectively analyzed. All the patients underwent a marginal osseous resective jaw surgery. A clinical 12 months postoperative evaluation has been performed and the complete mucosal healing, the absence of swelling and suppuration, and no signs of disease recurrence were defined like success parameters. Quality-of-life surveys tests like EORTC QQ-C30 and QLQ-HN35 appendices in conjunction with a perceived oral health visual analog scale (VAS) were administered before (time of diagnosis of MRONJ) and after surgery (at least 6 months) in order to record the different oral health status of the treated patients. The majority of MRONJ-diagnosed patients complained symptoms like pain, eating discomfort, and sense problems, with occasional involvement of the social dimension. There was a prevalence of troubles with social eating and social contact.The complete mucosal healing was achieved in 100% of the patients and the administered survey tests reported a significant improvement in all the investigated spheres. Similarly, an increased mean score of perceived oral health VAS was reported.Marginal-resective surgery of the necrotic jaw bone can be an effective treatment of osteoporotic patients affected by localized MRONJ. Quality-of-life parameters are demonstrated to be useful for recording the patient-centered outcome of MRONJ treatment.

OBJECTIVES: To evaluate non-invasively the morphological features of both lateral pterygoid muscle (LPM) and masseter muscle by using diffusion tensor Imaging on two patients affected by mandibular asymmetry. METHODS: Two female patients with mandibular excess and asymmetry who underwent Le Fort I osteotomy and bilateral sagittal split osteotomy were recruited for this study. Morphological (T1 weighted) and diffusion weighted images were acquired with a 3T scanner 1 week before (T0) and 1 month after the surgery (T1). Probabilistic tensor-based tractography reconstruction of bilateral masseters and LPMs was performed and mean fractional anisotropy (FA) values for both muscles were extracted. RESULTS: Diffusion tensor imaging was able to identify the muscle geometrical morphology and diffusion microstructural changes. Both at T0 and T1, mean FA values had no significant differences between the right and left side of masseter (at T0: p = 0.91; at T1: p = 0.54) and LPM (at T0: p = 0.92; at T1: p = 0.43), respectively. Both patients reported a significant improvement in FA mean values of the left LPM (p = 0.03) between T0 and T1, whereas no diffusion parameters' changes were observed for the bilateral masseter muscles and right LPM. CONCLUSIONS: We found that after the surgery the LPM ipsilateral to the deviation side showed a significant increase of FA compared to the baseline. Although preliminary, our findings suggest that diffusion tensor imaging may represent a promising tool to investigate non-invasively the masticatory muscles in temporomandibular joint disorders.

BACKGROUND: Orbital fractures are classified as diseases usually related to common midface trauma. It represents the most challenging treatment due to the complex anatomy, physiology, and aesthetic role. A midface trauma involves also the zygomatic complex and the nose, however the orbit fracture seems to be a more frequent disease due to its anatomical features. OBJECTIVE: The purpose of this work is to retrospectively evaluate and record the frequency of the midfacial traumas and orbital fractures observed in the North Eastern Sicily. The results of the present data may be useful for the clinicians in order to recognize the kind of fracture just from the first general visit having a quick diagnosis and management. METHODS: In the years between 2001 and 2016, about 1200 patients with midfacial trauma and about 100 patients involving the orbital floor have been evaluated. All those patients underwent the surgical fracture reduction and a CT scan follow up control at one month, three months, six months and one year. RESULTS: Data showed high percentage of orbital floor, nose and mandibular body and ramus fractures; moreover the most frequent causes of fractures seem to be related to motor vehicle accident, followed by assaults, work and fall. CONCLUSION: The results have highlighted the changing trends in the causes of facial injuries, particularly the increasing incidence of assaults and the falling incidence of motor vehicle accidents in developed countries. The quick diagnosis and management proved fundamental for the successful treatment. Clinicians should be able to recognize the first symptoms in order to avoid possible complications.
RESUMEN
Cases of medication-related osteonecrosis of the jaw (MRONJ) have been more commonly associated with aminobiphosphonate therapy than with alkylbiphosphonate treatment. Here, we report a case of MRONJ in a subject who received an alkylbiphosphonate, clodronate, for the treatment of osteoporosis, and discuss the pathogenic mechanisms of alkylbiphosphonates and the possible reasons for the spontaneous and rapid remission of MRONJ occurring in our patient.

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.

Osteonecrosis of the jaw (ONJ) is an adverse effect of bisphosphonate treatment that has become the subject of increasing investigations, in particular due to its poorly understood pathogenesis. Several experimental studies on animal models have been conducted; however, the majority of these replicate human ONJ following tooth extraction, and describe alterations in the bone and gingival epithelium when necrosis is manifested. The aim of the present study was to analyze the rat mandibular bone and gingival epithelium during 45 days of zoledronate treatment (which is a bisphosphonate agent), without tooth extraction. Intraperitoneal injections of zoledronate acid (0.1 mg/kg) were performed three times a week in normal male Wistar rats (n=20), while a control group of rats (n=20) was treated with saline solution for 45 days. After 7, 15, 30 and 45 days of drug treatment, all rats were sacrificed and hematoxilin and eosin staining, immunofluorescence and scanning electron microscopy analyses were performed. The results of the analyses after 7 and 15 days of treatment were similar in the treatment and control group. After 30 and 45 days of treatment, structural alterations were observed in the bone. No structural alterations to the gingival epithelium were observed. Based on these results, it was hypothesized that low doses of zoledronate act directly on the bone tissues to induce morphological alterations from bone to necrotic tissue following surgical procedures, although no cytotoxic effects were detected in the gingival epithelium.
RESUMEN
Plasma cell tumors are lymphoid neoplastic proliferations of B cells. Multiple myeloma is the disseminated type of this disorder, while localized forms of plasma cell neoplasms are solitary plasmacytoma of bone that is observed as centrally localized in bones, and extramedullar plasmacytoma (EMP) that develops in soft tissues. EMP of the head and neck region is a rare malignant tumor comprising approximately 3% of all plasma cell tumors, and approximately 0.4% of all head and neck malignancies; among them, plasmacytoma of the maxilla is extremely rare. The authors present a case of a patient affected by an EMP of the maxilla simulating a maxillary radicular cyst comparing our results with the recent literature. EMP entity requires a meticulous overview of the patient by the specialist and overall the control of any signs or symptoms of systemic diseases, a fact that would mark a dramatic change in the treatment and prognosis for the patient.
