“…Color doppler ultrasound results of single TDC cases typically reveal single round or circular-like lesions with clear borders and few or no point-like echogenic areas. 18 Here, color doppler ultrasound assessments of 11 double TDC cases revealed double-cystic masses or masses containing suspected internally separate multiple cysts or gourd-shaped structures. Importantly, Importantly, CT and MRI scans can indicate mass sizes and their relationships with surrounding tissues and thus are highly valued for use in cyst characterization and localization.…”

“…Imaging is an important TDC diagnostic tool, with color doppler ultrasound serving as the preferred imaging method used for diagnosing TDC, followed by CT and magnetic resonance imaging (MRI). Color doppler ultrasound results of single TDC cases typically reveal single round or circular-like lesions with clear borders and few or no point-like echogenic areas 18 . Here, color doppler ultrasound assessments of 11 double TDC cases revealed double-cystic masses or masses containing suspected internally separate multiple cysts or gourd-shaped structures.…”

This retrospective study aimed to investigate clinical diagnostic and management characteristics of double thyroglossal duct cyst (TDC) cases. Seventy-eight patients diagnosed with TDCs who were admitted to the inpatient ward of the Department of Otolaryngology, Dalian Central Municipal Hospital from June 2008 to October 2021 were included in the study. Ultimately, 67 of these patients were diagnosed with single TDCs and 11 patients with double TDCs. Each patient underwent computed tomography and color doppler ultrasound imaging of their neck masses, thyroid color doppler ultrasound imaging, and surgical cyst removal through the classic Sistrunk procedure. All surgically excised specimens were sent to the pathology lab for examination and were confirmed to contain TDCs. Two of the 67 patients with single TDCs experienced postoperative complications related to infections within the operative area, whereas no patients with double TDCs experienced postoperative infection, excessive bleeding, or other surgical complications. All cases were followed up for 1 to 3 years after surgery with no cyst recurrence observed. Double TDCs may present on physical examination as unilateral neck masses that interfere with tongue extension and movement and swallowing that can be identified using imaging methods. Correct clinical diagnosis and complete surgical removal of cysts are key measures for ensuring successful treatment outcomes for patients with TDCs.

“…Finding out the features of morphogenesis and topographic changes of suprahyoid region (SHR) of the neck and its structures in the dynamics of human intrauterine development (IUD) remains a relevant area of morphological research [1][2][3][4][5]. Refined, comprehensive data on gender, age and constitutional features of the structure and topography of organs and structures of the SHR of the neck during the prenatal period of human ontogenesis will make it possible to develop new criteria for the interpretation of medical diagnostic imaging data, the degree of fetal viability, improve existing and develop new methods of surgical correction of congenital neck defects [6][7][8][9].…”

The aim: To determine the peculiarities of the morphometric parameters of suprahyoid region of the human prefetuses. Materials and methods: Thirty specimens of human prefetuses of 14.0-80.0 mm parietococcygeal length (PCL) (7-12 weeks of IUD) were studied using a complex of modern methods of morphological research. Results: On the basis of obtained digital indicators of the main morphometric parameters of human SHR in the dynamics of the prenatal period of IUD the critical periods of development of the region were clarified and mathematical functions that describe the normal course of organogenesis of SHR were created, which can be useful for creating diagnostic algorithms for the norm when carrying out prenatal diagnostics and monitoring the state of the fetus. It has been established that the 9-10th week of IUD is a critical period in the development of SHR, since during this time, intensive growth processes occur, which are manifested by a sharp change in the size of the organ, and this can lead to the appearance of variants of the structure and possible congenital defects of the SHR and the dental-maxillary apparatus in general. Conclusions: 1.Age-depended dynamics of changes in the anterior angle of the SHR shows an almost linear decrease in the angle by the end of the 9th week of IUD almost to 76°, after which it increases to almost 90° by the end of the 10th week. From the 11th week of the IUD, the anterior angle decreases again to 77 °, but begins to increase at the 12th week and by the end of the prefeal period. 2.The lateral length of SHR increases almost uniformly until the 9th week of IUD, during which its growth rate slows down. Starting from the end of the 10th week of IUD, this morphometric parameter begins to grow rapidly until the end of the prenatal period of ontogenesis. The growth rate of the lateral length of the SHR is described by the function: L lat = 1.1025 + 0.0015 x + 0.001 x2. 3.The width of the SHR from the 10th week of IUD begins to grow rapidly until the end of the prenatal period of development. The growth rate of the width of SHR is described by the function: W = 1.1025 + 0.0015 x + 0.001 x2. 4.Analysis of the age dynamics of the area of SHR demonstrates the exponential dependence on the age of the prefetuses, which is described by a mathematical function: A = 1,2452exp(0,0424x). Meanwhile, there is a slight slowdown in its growth rate at the 10th week of IUD with subsequent recovery of growth by the end of the prenatal period of ontogenesis. 5.The 9-10th week of IUD is a critical period in the development of SHR, since during this time, intensive growth processes occur, which are manifested by a sharp change in the size of the mandible.
