“…Several anatomical studies described the ADMB and DM fibrous sling variations [4,10]. The ADMB variants occur with an incidence ranging between 2.7% and 69.6% [3,5]. These aberrations are usually asymmetrical (20.7%) [6,11].…”

“…An independent muscle, the mentohyoid (of Macalister) extending between the body of the HB and the mandibular symphysis, may be found along the ADMB medial border and could be considered as the third head of a trigastric muscle. Rarely, the ADMB may be absent or atrophied [3]. In some cases, no IMT exists and the PDMB may insert onto the styloid process, while the ADMB inserts onto the lateral side of the HB.…”

“…These unilateral or bilateral muscle bundles or slips may occur as a result of a phylogenetic DM reduction or an unusual development of the ontogenetic material [2]. The ADMB is not identified in patients with hemifacial macrosomia and associated ipsilateral facial nerve palsy [3]. The accessory ADMBs may arise from the anterior belly itself, the IMT, the HB, the mandible or the digastric fossa and insert to the mylohyoid raphe, the HB, the mandible, the contralateral ADMB, or the MHM [4][5][6][7].…”

The anterior digastric muscle belly (ADMB) may present significant variations of substantial surgical importance. We present an unusual complex bilateral asymmetry of an accessory ADMB found when dissecting the submental area in a 72-year-old Greek male cadaver. A rare variant was recognized in the submental area constituted by a combination of bilateral asymmetry of the ADMB with unilateral absence of the intermediate tendon. The complex variant caused an obvious morphological asymmetry in the submental area. Such muscular variations may alter the surgical approach to the submental region. Clinicians involved in the treatment of this area should be aware of any possible variant, particularly when dealing with neck mass patients.

“…The tongue and the paired sublingual glands are also visualised (Figure 2). The paired digastric muscles lie superficial to the mylohyoid musculature and can demonstrate anatomical variants 13 . The geniohyoid‐genioglossus muscle complex is seen medially to the paired right and left sublingual glands and immediately deep to the mylohyoid muscle.…”

Sonography has long been recognised as the primary imaging modality in the evaluation of thyroid, parathyroid, nodal, and salivary gland pathologies. Since the late 1980‐2019's, the literature has described an evolving role for ultrasound in the assessment of the tongue and the floor of mouth. Ultrasound can be used for tumour staging, vascular malformations, and for the evaluation of tongue movement during phonation and in the sleep cycle. This article aims to introduce the sonographer to the basic technique, sonographic anatomy, and commonly encountered abnormalities of tongue ultrasound. It has been divided into three key sections: Anatomy, Function, and Physiology; ultrasound technique (Transcervical/Intra‐oral); common pathology.

“…2,[30][31][32][33][34][35][36][37][38][39] These variant muscles may travel unilaterally or traverse the midline. 2,[30][31][32][33][34][35][36][37][38][39] Therefore, variations in ABDM anatomy may potentially reveal equally diverse variation in RLAD anatomy. Variations in ABDM musculature may lead to surgical confusion during muscular medialization and suspension, which includes the ABDMs in a "digastric corset."…”

The anterior belly of the digastric muscle (ABDM) is important in numerous esthetic surgeries including rhytidectomy, alteration of the cervicomental angle via partial resection of the ABDM muscle belly, and suprahyoid muscular medialization and suspension. Recently, the connection between the ABDM and the mylohyoid muscle (MH) has been proposed as important for the mechanism of the digastric corset procedure. This report refers to the connection between the ABDM and the MH as a type of retaining ligament of the anterior digastric muscle (RLAD). This report is the first to directly demonstrate the existence of the RLAD, via photograph and video, and document variation in its attachment sites, its composition, and its behavior when traction forces are applied. In addition to the importance of the RLAD in plastic surgery, the RLAD may affect neurovascular structures between the ABDM and MH and serve as a physical barrier separating the submental fascial space from the submandibular fascial space and, therefore, influence the spread of infection.
