Currently, the first therapeutic option is sclerotherapy, leaving surgery for the treatment of remaining lesions. objective: To present a case of facial lymphatic malformation (LM) treated with sclerotherapy, surgery and orthodontics in a 15-year follow up. Case report: A one-year-old female patient who consulted health professionals due to a progressive volume increase of the soft parts of her right cheek. The imaging study confirmed the diagnosis of microcystic lymphatic malformation. It was managed with OK-432 sclerotherapy and Bleomycin. At 2 years of age, the patient response was considered adequate; an intralesional submandibular surgical excision was then performed, with partial resection of the lesion. The biopsy confirmed the diagnosis of microcystic LM. Six months after, a re-resection was planned using the same approach and removing the remaining lesion, with favorable development until the age of 9 years when the patient required surgery and orthodontic management due to intraoral recurrence. No major developments until the age of 13 when a new orthodontic surgery and handling are planned to perform right oral commissure suspension. Conclusion: LM management by sclerotherapy, surgery, and orthodontics has shown the advantages of a multidisciplinary long-term treatment in this case.
