Pediatric Head and Neck Surgery and Reconstruction
Congenital neck masses and their logic
In children, neck masses are usually congenital or inflammatory, unlike adults where malignancy is a greater concern. Midline masses: thyroglossal duct cyst (moves with tongue protrusion, Sistrunk procedure), dermoid. Lateral masses: branchial cleft anomalies (second most common; sinus tract along anterior border of SCM), cystic hygroma/lymphatic malformation (transilluminates, posterior triangle), and vascular malformations. Know that a lateral neck mass in an infant may be torticollis/fibromatosis colli, and that a rapidly enlarging inflammatory mass may be an abscess requiring drainage.
Concepts to master
Vascular anomalies classification (infantile hemangioma vs vascular malformation) and treatment: propranolol for problematic infantile hemangioma; sirolimus or sclerotherapy for lymphatic malformations. Understand indications for excision of branchial cleft anomalies and thyroglossal duct cysts (infection, cosmesis, malignancy risk). Pediatric head and neck oncology basics: neuroblastoma, rhabdomyosarcoma, lymphoma, and the importance of tissue diagnosis. Reconstruction principles: local flaps, skin grafts, and the role of growth in timing of reconstruction; cleft lip/palate timing (lip ~3 months, palate ~9–12 months) and speech outcomes.
Traps
Do not biopsy a suspected vascular malformation without imaging - bleeding risk. Do not assume a midline neck mass is a thyroglossal duct cyst without checking for ectopic thyroid. Avoid incomplete Sistrunk (recurrence). For cleft palate, remember that repair timing is driven by speech development and that velopharyngeal insufficiency may require secondary surgery.
Rule of thumb
Midline neck mass = thyroglossal duct cyst until proven otherwise; lateral = branchial cleft or lymphatic malformation. Image before you cut a vascular lesion.
Worked example
A 3-year-old with a painless, transilluminating posterior triangle mass since birth, now enlarging with a URI: lymphatic malformation. Management may include observation, sclerotherapy, or sirolimus; excision reserved for refractory cases.
