Extensive lymphangioma presenting with upper airway obstruction

Area of Science:

• Pediatric Otolaryngology
• Surgical Oncology
• Respiratory Medicine

Background:

• Lymphangiomas are benign congenital tumors that can cause significant morbidity in children.
• Airway compromise due to lymphangioma is a critical concern, particularly when involving the tongue base, parapharyngeal space, or larynx.
• Management of pediatric lymphangioma with airway obstruction presents complex challenges.

Purpose of the Study:

• To evaluate the surgical outcomes of pediatric lymphangioma cases presenting with dyspnea due to airway compression.
• To identify prognostic factors influencing treatment success in these patients.

Main Methods:

• Retrospective review of 18 pediatric cases of lymphangioma with airway encroachment treated between 1983 and 1998.
• Surgical interventions included neck dissection, tracheotomy, V glossoplasty, cervicotomy, endoscopy, CO2 laser photocoagulation, and supraglottic laryngectomy.
• Outcome measures focused on residual disease, tracheotomy status, and persistent respiratory symptoms.

Main Results:

• A 50% rate of tracheotomy was required initially. Of those, 89% were decannulated after an average of 22 months.
• Residual lymphangioma was observed in 94% of patients postoperatively.
• Ten patients experienced persistent respiratory symptoms, while 6 remained asymptomatic.

Conclusions:

• External compression of the airway by cervical lymphangioma responds well to surgical intervention.
• Intrinsic involvement of the upper airway by lymphangioma appears to be a negative prognostic factor, with aggressive surgery offering limited benefit.
• Less aggressive, symptomatic management may be a viable alternative for patients with intrinsic airway involvement to avoid extensive surgical procedures.
