Surgical treatment of Ranula with carbon dioxide laser radiation
Lasers in Medical Science, 2004Co-Authors: W. Niccoli-filho, A. R. C. MorosolliAbstract:Ranula is a mucous extravasation cyst which appears as a swelling in the submental and submandibular regions. Several surgical techniques to manage Ranula have been described in the literature, these techniques include the CO_2 laser radiation excision. Four patients were treated for intraoral Ranula in the floor of the mouth by marsupialization with carbon dioxide laser radiation with defocused beam, continuous mode and 4 watts of power. There were no complications and no recurrences have occurred to date. The results showed that carbon dioxide laser radiation gives optimal results with no need for suture and good wound healing.

submandibular gland mucocele presenting as a lateral neck swelling
Journal of Surgical Case Reports, 2012Co-Authors: A M Felstead, P M Patel, P J RevingtonAbstract:Mucus extravasation cysts or mucoceles are an extremely rare occurrence in the major salivary glands. We report upon an unusual case of a submandibular gland mucocele presenting as a neck lump. It should therefore be considered in the differential diagnosis of swellings in the lateral neck. Diagnosis and management are complicated by their similarity to the plunging or cervical Ranula and differentiation may be potentially difficult. Detailed imaging often reveals the plunging Ranula as being characterised by a so –called ‘tail’ sign. In our case this sign was absent and subsequent excision confirmed origin from the submandibular gland. We discuss potential treatment modalities and propose a rationale for definitive management.

postmortem investigation of mylohyoid hiatus and hernia aetiological factors of plunging Ranula
Clinical Anatomy, 2013Co-Authors: John Harrison, Ann Kim, Saad Alali, Randall P MortonAbstract: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. Clin. Anat. 26:693–699, 2013. © 2013 Wiley Periodicals, Inc.

modern management and pathophysiology of Ranula literature review
Head and Neck-journal for The Sciences and Specialties of The Head and Neck, 2010Co-Authors: John HarrisonAbstract:Background There is a lack of consensus about the appropriate treatment of Ranula. The objective of the present investigation was to produce a scientific basis for treatment. Methods A review of the relevant literature is interpreted in the light of improved knowledge about the local anatomy and the pathophysiology of the salivary glands. Results The oral and plunging Ranulas are cystic extravasation mucoceles that arise from the sublingual gland and usually from a torn duct of Rivinus. The sublingual gland is a spontaneous secretor and the salivary flow is resistant to obstruction, which is caused by fibrosis induced by the extravasation. The submandibular gland is not a spontaneous secretor, is less resistant, and does not give rise to Ranulas. Conclusions Effective treatment is removal of the involved unit of the sublingual gland or inducing sufficient fibrosis to seal the leak through which the mucus extravasates. © 2010 Wiley Periodicals, Inc.

conservative treatment of oral Ranula by excision with minimal excision of the sublingual gland histological support for a traumatic etiology
Journal of Oral and Maxillofacial Surgery, 2008Co-Authors: Mark Mcgurk, Josiah Eyeson, Bethan Thomas, John HarrisonAbstract:Purpose: This study investigates, clinically and histologically, a new conservative technique for the treatment of oral Ranula based on the premise that a discrete unit of the sublingual gland feeds the Ranula, which can therefore be treated by local removal with the attached part of the sublingual gland. Patients and Methods: The study group consisted of 8 patients with Ranula treated by decompression of the Ranula followed by local surgical removal together with the attached part of the sublingual gland. Detailed histologic examination of the entire specimen was undertaken in every case. Results: The treatment was successful in all the patients and there have been no recurrences after reviews of from 13 to 29 months (median, 26 months). Histologic examination of the entire specimen showed communication between the removed part of the sublingual gland and the Ranula by way of a torn duct in every case. Conclusions: The premise that the Ranula is fed by an attached, discrete unit of the sublingual gland has been vindicated and is the basis for the successful conservative treatment of Ranula by decompression and local surgical removal together with the attached part of the sublingual gland. The finding of communication between the attached sublingual gland and Ranula in every case indicates a traumatic etiology for these Ranulas. © 2008 American Association of Oral and Maxillofacial Surgeons J Oral Maxillofac Surg 66:2050-2057, 2008 Most Ranulas are large extravasation mucoceles that arise from the sublingual gland and are sufficiently extensive to form a swelling that resembles the belly or vocal air sac of frog. They are cystic and are frequently blue owing to the Tyndall effect, whereby blue light is reflected more than red light at the interface of soft tissue and cyst. Most extravasation mucoceles occur in the lower lip 1 and are treated successfully by removal of the mucocele with the feeding minor salivary gland. Although the floor of the mouth is the second most common site for extravasation mucoceles, 1 the treatment of the Ranula is varied and not always successful. 2-6 Treatment by incision, simple marsupialization, and ex
