The anatomical basis and rational for the transoral approach during the surgical excision of the sublingual salivary gland for the management of plunging ranula.

PURPOSE: The aim of this study was to illustrate and confirm that the complete intraoral excision of the sublingual gland alone, is anatomically the most rational approach, for the management of plunging ranula. MATERIAL AND METHODS: We retrospectively reviewed clinical charts of diagnosed HIV-infected patients presenting with plunging ranula. The intraoral approach was used for the complete excision of the sublingual gland with evacuation of the pseudocystic content only. Neither extra oral approach, nor ranula dissection / drainage was performed. The surgical procedure was performed using local anesthesia. Pre- and postoperative MRI-scan investigations were recorded. Histological reports were documented to confirm the diagnosis of oral mucocele. Patients were clinically monitored. RESULTS: We identified 90 adults presenting with oral mucocele, type ranula. Seventy (77%) of them were diagnosed with HIV infection. Plunging ranula was recorded in 35 (50%) patients from the latter group. The study enrolled 11 operated patients whose files contained useable data, including an acceptable follow-up period. The postoperative follow-up period ranged from three to 15 months. The clinical and postoperative MRI-scans of operated patients demonstrated satisfactory results. There were neither postoperative complications nor recurrence of ranula reported. CONCLUSION: The location of the sublingual gland in the floor of the mouth coupled with the physio-pathogenesis of the plunging ranula, makes the transoral complete excision of the offending gland, with the intraoral evacuation of the pseudocyst, anatomically the most rational approach for plunging ranula management. There is no need for cervical approach, ranula dissection and/or postoperative placement of drainage.

Oral mucocele/ranula: Another human immunodeficiency virus-related salivary gland disease?

OBJECTIVES/HYPOTHESIS: To describe clinical characteristics of oral mucoceles/ranulas, with a focus on human immunodeficiency virus (HIV)-related salivary gland diseases. STUDY DESIGN: A descriptive and clinical study, with review of patient data. MATERIAL AND METHODS: We reviewed 113 referred cases of oral mucocele. The following anatomical sites were identified: lip, tongue, and floor of the mouth (simple ranulas), as well as plunging ranulas. The age and gender data of the patients with oral mucoceles were recorded. The HIV status of the patients and other information were reviewed. RESULTS: There were 30 (26.5%) males and 83 (73.5%) females. Most patients were below 30 years of age, with the peak frequency in the first and second decade. Ranula (simple and plunging) represented 84.1% of the mucocele locations. Mucocele on the lips represented 10.6%. Seventy-two (63.7%) patients were HIV positive; and 97.2% of them had ranulas. Thirty-eight (33.6%) patients presented with plunging ranulas; and 92.1% of them were HIV positive, compared with two patients presenting with plunging ranulas in the HIV-negative group. These results strongly suggest that an HIV-positive patient is statistically (P < 0.001) more at risk of presenting with not only a simple, but also a plunging ranula type. CONCLUSION: This study presents a different clinical picture of oral mucoceles/ranulas, as observed in HIV-positive patients. Additionally, it suggests a possible clinical link between the two pathologies. The authors strongly support the suggestion that oral mucocele/ranula is an HIV-related salivary gland disease. LEVEL OF EVIDENCE: 4.

The potential impact of highly active antiretroviral therapy on the treatment and epidemiology of ranula in human immunodeficiency virus-positive patients.

OBJECTIVE: The study's aim was to assess the potential therapeutic effect of highly active antiretroviral therapy (HAART) on ranulas in human immunodeficiency virus (HIV)-positive patients. STUDY DESIGN: The study includes a retrospective observation of 3 patients who were initially part of a prospective study on the comparative effect of HAART on ranulas in 14 HIV-positive patients. These patients were clinically monitored while pursuing the medical treatment with HAART. Neither a fine needle aspiration nor a surgical procedure was performed. Clinical photographs were used for monitoring of any reduction in the ranula size. The effect of HAART on ranula was assessed at 3, 6 and 12 month. RESULTS: A complete resolution of the ranula lesion was noticed in the 3 HIV-positive selected patients. These results were observed between 6 and 12 months period. CONCLUSION: This study suggests that HAART might present a potential therapeutic effect on ranula in HIV-positive patients.
