Classification specific lymphatic malformations management on head and neck in children

Area of Science:

• Pediatric Surgery
• Vascular Anomalies
• Head and Neck Surgery

Background:

• Lymphatic malformations (LMs) are congenital vascular anomalies affecting the head and neck in children.
• Treatment outcomes for pediatric head and neck LMs vary significantly based on malformation type and treatment modality.
• A comprehensive analysis of surgical versus nonsurgical approaches is crucial for optimizing patient care.

Purpose of the Study:

• To retrospectively analyze and compare the outcomes of surgical and nonsurgical treatments for pediatric head and neck lymphatic malformations.
• To evaluate the effectiveness of different treatment strategies based on LM characteristics.

Main Methods:

• Retrospective analysis of 58 pediatric patients with head and neck LMs.
• Patients were categorized into a surgical group (n=22) and a nonsurgical group (n=36).
• Treatments included surgery, sclerotherapy, and microwave ablation (MWA), with interventions tailored to LM type (microcystic, macrocystic, mixed) and location.

Main Results:

• In the surgical group (mean follow-up 44 months), 68.2% achieved complete LM control.
• In the nonsurgical group (median follow-up 23.5 months), 77.8% showed >50% volume reduction, with 16.7% experiencing complications.
• Sclerotherapy and MWA demonstrated high efficacy for macrocystic and mixed LMs.

Conclusions:

• Surgery is indicated for early-stage, well-defined microcystic LMs.
• Sclerotherapy is effective for macrocystic and mixed LMs.
• Combination therapy with sclerotherapy and MWA shows promise for complex, large cystic LMs.
