Surgical excision of the submandibular salivary gland in patients with chronic sclerosing sialadenitis can be complicated because of hyalinosis of the surrounding soft tissues. Patients with autoimmune diseases suspected of having salivary gland neoplasms or granulomatous disease should be carefully investigated for chronic sclerosing sialadenitis to prevent potential harm.

Background The aim of this study was to perform a retrospective analysis of the prevalence, etiologies, types of maxillofacial injuries (MFIs), sites of maxillofacial fractures (MFFs) and their management in Yerevan, Armenia. Methods A retrospective cross-sectional study was conducted. The extracted data included age, sex, date of referral, mode of injury, etiology, radiology records and treatment methods. Study outcomes were measured using percentages, means, standard deviations and tests of proportions. P < .05 was considered significant. Results A total of 204 patients had a mean age of 36.26 ± 1.08 years (156 males and 48 females), and a total of 259 MFIs were recorded between 2017 and 2020. Interpersonal violence was found to be the most common etiology of MFFs in this study (42.1%), followed by road traffic accidents (RTAs) (27.9%) and falls (18.6%). The nasal bone was the most common injury site (47.5%), followed by the mandible (31.4%) and zygomatic complex (11.7%). The most common fracture site was the mandibular angle (37.9%), followed by the symphysis/parasymphysis (28.1%) and body (12.6%). Isolated soft tissue injuries were reported in 5.9% of the cases. The majority of MFFs were treated by open reduction and internal fixation. Conclusion Interpersonal violence, followed by RTAs and falls, was the most common cause of MFIs. Males in the 21–30 years age group had the highest MFI incidence rate. The nasal bone was the most common injury site, followed by the mandible and zygomatic complex. Social education with the objective of reducing aggression and interpersonal conflict should be improved, and appropriate RTA prevention strategies should be strengthened and implemented.

Objective: The aim of this study was to perform a retrospective analysis of the prevalence, etiologies, and types of maxillofacial injuries (MFI) and sites of maxillofacial fractures (MFF) and their management in the Department of ENT and Maxillofacial Surgery of "Heratsi" No. 1 University Hospital in Yerevan, Armenia. Material and methods: A retrospective cross-sectional study was conducted. Data including age, sex, date of referral, mode of injury, etiology, radiology records and treatment methods were extracted. Study outcomes were measured using percentages, means, standard deviations and tests of proportions. P <.05 was considered significant. Results: A total of 204 patients had a mean age of 36.26 years (156 males and 48 females), and a total of 259 MFIs were recorded between 2017 and 2020. Interpersonal violence (IV) was found to be the most common etiology of MFFs in this study (42.1%), followed by road traffic accidents (RTAs) (27.9%) and falls (18.6%). The nasal bone was the most common injury site (47.5%), followed by the mandible (31.4%) and zygomatic complex (11.7%). The most common fracture site was the mandibular angle (37.9%), followed by the symphysis/parasymphysis (28.1%) and body (12.6%). The majority of MFFs were treated by open reduction and internal fixation. Conclusion: Interpersonal violence, followed by RTAs and falls, was the most common cause of MFIs. The nasal bone was the most common injury site, followed by the mandible and zygomatic complex. Social education with the objective of reducing aggression and interpersonal conflict should be improved, and appropriate RTA prevention strategies should be strengthened and implemented.

The purpose of this clinical report is to evaluate the clinical performance of customized titanium implants (PSI) using virtual 3D planning and computer-assisted implant fabrication (CAD/CAM process) and based on preoperative CT data, the placement accuracy and the risk of postoperative complications. This work has shown that 3D printed titanium base implants can significantly improve the outcomes of patients requiring skull reconstruction surgery. By choosing the appropriate design method, manufacturing process, and implant material, you can get a more accurate procedure, reduce surgery time, prevent various complications that can occur with the traditional method, and get predictable results compared to the traditional method.

Nodular fasciitis (NF) is a benign reactive or inflammatory condition of mesenchymal fibroblasts. Rapid growth and histological features make nodular fasciitis a mimicker of malignancies such as sarcomas, however, nodular fasciitis is a benign lesion and does not metastasize. Although the etiology of nodular fasciitis is uncertain, histopathologically, it bears a close resemblance to organizing granulation tissue, and myofibroblastic proliferation may be initiated by a local injury or local inflammatory process, which supports a reactive proliferation theory triggered by trauma. Surgical excision is recommended for diagnosis and treatment to exclude malignancy. We are hereby reporting a case of nodular fasciitis on the front surface of the neck, 86 years old patient. Tumor grew rapidly and reached 9-10 cm., and which was clinically suspected as a malignancy located. An ultrasound examination was performed. Based on the clinical and ultrasound data, it was decided to perform an extended biopsy to establish the final diagnosis it. Tumor has been removed as a solid mass. The material was sent for histopathological examination. Based on the history, clinical picture, and histopathological examination, the lesion was diagnosed as nodular fasciitis. After surgery patient expressed satisfaction with the result of treatment. In cases of nodular fasciitis, proactive efforts are needed to perform histopathologic evaluation and treatment because nodular fasciitis tends to grow rapidly.
