Background/Aim: Mylohyoid boutonnière is a common anatomical variant with extremely rare clinical manifestations. We report two cases of symptomatic unilateral mylohyoid boutonnière with sublingual gland herniation. Case report: The first was a 34-year-old female with a two months history of a left submandibular swelling, intermittent pulsations, and otalgia. The second 67-year-old female presented with a left submandibular pain six months after total thyroidectomy due to papillary carcinoma. After detailed clinical and radiological evaluation by ultrasonography (US) and computed tomography (CT), the mylohyoid gap with sublingual gland herniation was diagnosed in both patients. The dynamic US with a tongue pressed down on the mouth floor revealed blood vessel compression by a herniated sublingual gland in the first patient. Conclusions: This is the first case of a mylohyoid boutonnière related intermittent vascular compression. Dynamic US and CT may help to differentiate intermittent and persistent sublingual gland herniation through the mylohyoid boutonnière from other pathological lesions in the submandibular region.

Background: The mortality of oral squamous cell cancer (OSCC) in Serbia increased in the last decade. Recent studies on the Serbian population focused mainly on the epidemiological aspect of OSCC. This study aimed to investigate the demographic and imaging features of OSCC in the Serbian population at the time of diagnosis. Methods: We retrospectively analyzed computed tomography (CT) images of 276 patients with OSCC diagnosed between 2017 and 2022. Age, gender, tumor site, tumor volume (CT-TV, in cm
3 ), depth of invasion (CT-DOI, in mm), and bone invasion (CT-BI, in %) were evaluated. TNM status and tumor stage were also analyzed. All parameters were analyzed with appropriate statistical tests. Results: The mean age was 62.32 ± 11.39 and 63.25 ± 11.71 for males and females, respectively. Male to female ratio was 1.63:1. The tongue (36.2%), mouth floor (21.0%), and alveolar ridge (19.9%) were the most frequent sites of OSCC. There was a significant gender-related difference in OSCC distribution between oral cavity subsites (Z=-4.225; p < 0.001). Mean values of CT-TV in males (13.8 ± 21.5) and females (5.4 ± 6.8) were significantly different (t = 4.620; p < 0.001). CT-DOI also differed significantly (t = 4.621; p < 0.001) between males (14.4 ± 7.4) and females (10.7 ± 4.4). CT-BI was detected in 30.1%, the most common in the alveolar ridge OSCC. T2 tumor status (31.4%) and stage IVA (28.3%) were the most dominant at the time of diagnosis. Metastatic lymph nodes were detected in 41.1%. Conclusion: Our findings revealed significant gender-related differences in OSCC imaging features. The predominance of moderate and advanced tumor stages indicates a long time interval to the OSCC diagnosis. [ABSTRACT FROM AUTHOR]- Published

Hyperostosis frontalis interna (HFI) is the overgrowth of bony tissue on the inner plate of the frontal bone. Females manifest significantly higher prevalence of HFI compared to males, with the peak incidence in postmenopausal women. Etiopathogenesis of HFI is still ambigous. Different hormonal imbalances i.e. prolonged estrogen stimulation during reproductive period, or abnormal progesterone effect on the ovaries, or inadequate androgen stimulation are pointed out in the literature as the most probable causes of HFI, due to its high prevalence and severity in the females, as well as the fact that in males only those with hypogonadism manifest advanced stages of HFI. Several models have tried to provide an adequate explanation of HFI developement. The most recent is the „global model“ which states that neovascularization originating from dura, might be one of the key processes in its formation. Some studies suggested that women with HFI tend to develop more robust skull characteristics. However, there are no studies that investigated whether HFI is accompanied by changes in bone thickness or density in postcranial skeleton. Present macroscopical classification of HFI is based on morphological characteristics and extension of frontal bone involvement and includes four different types of HFI. Relatively low percentage of radiological recordings of HFI may ocure due to the fact that present macroscopical method of identification and classification encompasses multiplanar reconstruction of head CT scans, which makes it complicated for routine radiological practice. Additionally, it remains unclear whether different macroscopic stages of HFI can be regarded as successive phases in the process of HFI development... Hyperostosis frontalis interna (HFI tj. ХФИ), представља нагомилавање коштаног ткива локализовано на унутрашњој површини фронталне кости. Чешће се јавља код особа женског пола са највишом инциденцом забележеном код жена у постменопаузи. Етипатогенеза ХФИ и даље није разјашњена. Различити хормонски дисбалaнси као што је пролонгирана естрогена стимулација током репродуктивног периода, поремећена продукција прогестерона од стране оваријума или неадекватна андоргена стимулација су у литератури наведени као највероватнији узрочници настанка ХФИ, имајући у виду високу преваленцу и израженију манифестацију ХФИ код жена, као и чињеницу да се само код мушкараца са хипогонадизмом јављају изражене форме ХФИ. Неколико модела је понуђено као могуће објашњење процеса настанка ХФИ. Најновији је “глобални модел“, по коме неоваскуларизација, пореклом из дуре, може бити један од кључних процеса у настанку ХФИ. У појединим студијама примећено је да жене са ХФИ могу развити робусније морфолошке карактеристике лобање у односу на оне без ХФИ. Међутим, не постоје студије које су испитивале да ли је ХФИ праћена променама у коштаној густини и спољашњој морфологији и у посткранијалном делу скелета. Постојећа макроскопска класификација ХФИ је базирана на морфолошким карактеристикама и обиму захваћености фронталне кости и обухвата четири различита типа ХФИ (А, Б, Ц и Д). Релативно низак проценат бележења ХФИ од стране радиолога, може се објаснити чињеницом да постојећи макроскопски метод класификације и идентификације ХФИ обухвата тродимензионалну реконструкцију прегледа главе начинјених методом компјутеризоване томографије (CT), и да је као такав, сувише компликован за рутинску радиолошку праксу. Такође, и даље није познато да ли различити макроскопски типови ХФИ могу бити посматрани као сукцесивне фазе у процесу настанка ХФИ...
