Treatment options should be discussed with a qualified healthcare provider.
OK-432 Picibanil Sclerotherapy
Injection of OK-432, an immunomodulatory agent, into the cystic components to stimulate inflammatory response and permanent shrinkage. Particularly effective for macrocystic lesions with established safety profile.
Sirolimus Monotherapy
Oral administration of sirolimus to inhibit mTOR signaling and reduce lymphatic malformation proliferation. Evidence supports use in complex or multifocal disease unresponsive to conventional therapies.
Additional treatment options
Elective Excision with Tissue Preservation
Planned surgical removal of symptomatic portions of the malformation while preserving critical adjacent structures. Elective timing allows optimal pre-operative planning and patient preparation.
surgicalPsychosocial Support and Counseling
Professional psychological support addressing body image concerns, social anxiety, and coping strategies for chronic disease management. Particularly important for facial or visible lesions causing distress.
psychologicalAspiration with Adjunct Sclerotherapy
Initial needle aspiration to decompress large cystic components followed immediately by sclerotherapy injection to prevent fluid re-accumulation. Combined approach improves efficacy over aspiration alone.
