Retropharyngeal lymphatic malformations (LMs) are exceedingly rare and have rarely been reported in the literature. This condition can be life threatening, and its management is particularly challenging. Over a two-year period, two patients who presented with symptomatic (dyspnoea, snoring) retropharyngeal LMs were treated in our hospital. Both patients were treated using radiofrequency ablation of LMs through a trans-oral approach and bleomycin sclerotherapy as adjunctive treatment. No major complications occurred following surgery.
During follow-up, no recurrence was noted, and both patients were asymptomatic. Our result suggests that radiofrequency ablation combined with bleomycin sclerotherapy can be a safe and effective treatment.
