Objective:
To evaluate ranula development according to anatomic variation of the ductal system of sublingual gland (SLG), especially the presence of Bartholin's duct.
Methods:
The anatomic variation of SLG duct was prospectively investigated and compared between 55 consecutive patients with ranulas treated by SLG excision (group 1) and another 15 consecutive patients undergoing similar surgeries for other conditions (group 2). The ductal structures of SLGs and submandibular glands (SMG) were also compared between the pediatric patients and adult patients with ranulas.
Results:
In 32 of 55 patients with ranulas (58.2%) and 1 of 15 patients without ranulas (6.7%), the SLG showed an anatomic variation of the main duct called Bartholin's duct structure (P<0.01). Seventeen of 22 (77.3%) pediatric patients with ranulas had Bartholin's ducts and 15 of 33 (45.5%) adult patients with ranulas had Bartholin's ducts (0.01
Conclusions:
Congenital anatomic variation of the ductal system of the SLG might be a possible cause of ranulas in the patients with simple ranulas, especially in pediatric patients. Surgical resection of the SLG is a better treatment choice for ranulas than other conservative treatments.

Salivary Glands and Saliva
Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
Exocrine Glands: Types of Secretions
Serous glands produce watery secretions rich in digestive enzymes and proteins. The constituent cells of the serous gland have centrally located nuclei and eosinophilic secretory granules in the cytoplasm. The parotid gland is an example of a serous gland. It secretes saliva, which contains enzymes, such as lipases and...

Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
Renal Tubule and Collecting Duct
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
