[Clinical analysis of maxillofacial adipocytic neoplasia in children]

Objective: To explore the clinical manifestations, diagnosis, treatment and prognosis of maxillofacial adipocytic neoplasia in children. Methods: The clinical data of 8 children with maxillofacial adipocytic neoplasia admitted to Shanghai Children's Hospital from August 2014 to July 2019 were retrospectively analyzed, including 6 males and 2 females, aged from 8 months to 8 years 11 months, with an average age of 44 months. The clinical characteristics, imaging findings, treatment methods and effects of 8 patients were analyzed. Results: Among the 8 patients, 5 were lipomas and 3 were lipoblastomas; 4 were in the masseter muscle region of the parotid gland, 2 were in the parapharyngeal space and 1 was in the submandibular and nasal areas separately. The clinical manifestations were mainly painless maxillofacial masses, sleep snoring and pharyngeal foreign body sensation. All of 8 patients underwent surgical treatment without complications such as infection, facial paralysis, and salivary fistula. No recurrence was observed during a follow-up of 6 months to 5 years. Conclusions: Lipoma and lipoblastoma are the main tumors of maxillofacial adipocytic neoplasia in children. The appropriate surgical incision and surgical method can be selected according to the characteristics of the area of the tumor combined with preoperative imaging examination. The prognosis of the disease is good and recrudescence is rare.
