Diode laser assisted excision and low level laser therapy in the management of mucus extravasation cysts: A case series

Introduction: mucus extravasation cyst is a commonly occurring lesion in oral cavity that may result from traumatic severance of a salivary gland duct with subsequent extravasation of mucus into fibrous connective tissue. after a conventional excision or marsupialization,recurrence is not uncommon. diode laser offers an effective modality for management of such lesions. case reports: four patients were referred with painless fluctuant swellings on labial and buccal mucosa. after recording history and clinical examination,provisional diagnosis of mucocele was made. all the lesions were excised with a diode laser and biopsy was performed. surgical wounds were treated with low-level laser therapy (lllt). results: uneventful healing was observed in all 4 cases. significant reduction in postoperative discomfort was recorded after application of lllt. histopathological findings were suggestive of mucus extravasation cysts. conclusion: diode laser appears to be a good alternative to conventional modalities for the management of mucus extravasation cysts.
