“…A wide variation in the incidence of the defects of the mylohyoid muscle has been reported in the literature. In the cadaveric dissection studies, the reported incidence ranged from 10% to 72% ( 13 14 15 16 ). These defects also can be detected on imaging studies.…”

“…Defects tend to be located along the lateral margins of the mylohyoid muscle, closer to the mandible and away from the median raphe, almost always in the anterior half of the mylohyoid-mandible attachment ( 7 12 ). Various anatomic structures pass through the defects, including salivary tissue, fat, and blood vessels ( 6 12 13 14 15 16 ). According to Engel et al ( 15 ), the histologic types of salivary tissue were either a mucous-type suggestive of sublingual gland or a mixed mucous-serous type with serous predominance suggestive of submandibular gland with a nearly equal prevalence.…”

ObjectiveThe purpose of this study was to clarify the pathogenesis of plunging ranulas in regard of the pathway of lesion propagation using CT scans.Materials and MethodsWe retrospectively reviewed CT scans of 41 patients with plunging ranula. We divided plunging ranulas into two types: type 1 was defined as those directly passing through a defect of the mylohyoid muscle with the presence (type 1A) or absence (type 1B) of the tail sign and type 2 as those through the traditional posterior route along the free edge of the mylohyoid muscle. Images were also analyzed for the extent of the lesion in respect to the spaces involved. As for type 1 lesions, we recorded the location of the defect of the mylohyoid muscle and the position of the sublingual gland in relation to the defect.ResultsCT scans demonstrated type 1 lesion in 36 (88%), including type 1A in 14 and type 1B in 22, and type 2 lesion in 5 (12%). Irrespective of the type, the submandibular space was seen to be involved in all cases either alone or in combination with one or more adjacent spaces. Of the 36 patients with type 1 lesions, the anterior one-third was the most common location of the defect of the mylohyoid muscle, seen in 22 patients. The sublingual gland partially herniated in 30 patients.ConclusionOur results suggest that the majority of plunging ranulas take an anterior shortcut through a defect of the mylohyoid muscle.

“…There have been many reports in the literature confirming the presence of asymptomatic herniation of the sublingual gland through mylohyoid defects based on cadaveric studies, CT, magnetic resonance imaging, and sonography. [4][5][6][7][8][9][10][11] Castelli et al 4 reported an occurrence rate of 10%; however, most other authors reported the incidence to be between 39% and 45%. [5][6][7] A retrospective CT study by…”

“…He considered that this explains how the plunging ranula arises from the sublingual gland. Although there has been a stream of publications in English since 1926 that have described these mylohyoid hiatuses with herniated sublingual gland (Malpas, ; Gaughran, ; Castelli et al, ; Schneider et al, ; Rayne, ; Mair et al, ; Braun and Sotereanos, ; McClatchey et al, ; Nathan and Luchansky, ; Coit et al, ; Engel et al, ; Moss‐Salentijn and Hendricks‐Klyvert, ; Bridger et al, ; de Visscher et al, ; Mizuno and Yamaguchi, ; Ichimura et al, ; White et al, ; Hopp et al, ; Windisch et al, ; Keberle et al, ; Kiesler et al, ; Ahmed et al, ; Jain et al, ; Morton et al, ; Samant et al, ; Haktanir, ), this feature is still not well known. Furthermore, the only extensive histological investigation of the mylohyoid hernia (Engel et al, ) purported to find submandibular gland in many of them, thereby supporting an opinion that the submandibular gland is the source of the plunging ranula.…”

Postmortem investigation of mylohyoid hiatus and hernia: Aetiological factors of plunging ranula

et al. 2013

The mylohyoid hiatus and hernia were discovered in the nineteenth century and were considered to explain the origin of the plunging ranula from the sublingual gland. This formed the rationale for sublingual sialadenectomy for the treatment of plunging ranula. However, a more recent, extensive histological investigation reported that hernias contained submandibular gland, which supported an origin of the plunging ranula from the submandibular gland and submandibular sialadenectomy for the treatment of plunging ranula. We therefore decided to investigate the occurrence and location of the hiatus and the histological nature of the hernia. Twenty-three adult cadavers were dissected in the submandibular region. The locations and dimensions of mylohyoid hiatuses were measured before taking biopsies of hernias. Hiatuses with associated hernias were found in ten cadavers: unilateral in six; and bilateral in four, in one of which there were three hiatuses. Sublingual gland was identified in nine hernias and fat without gland in six. This investigation supports clinical and experimental evidence that the plunging ranula originates from the sublingual gland and may enter the neck through the mylohyoid muscle. It confirms the rationale of sublingual sialadenectomy for the treatment of plunging ranula.
