SURGICAL OUTCOMES OF RADICAL MAXILIECTOMY IN MAXLLARY CANCER: COMPARED WITH TOTAL MAXILLECTOMY

초록

Objective: When the maxillary sinus cancer incades through the posterior wall into the infratemporal fossa, total maxillectomy, even if successfully carried out, has limitations in complete tumor removal with wide safety margins. We tried to find out the effect of radical maxillectomy for advanced maxillary sinus cancer by analyzing the surgical outcomes of radical maxillectomy in which the surgeon removes the tumor en bloc under direct vision of pterygoid muscle after exposing the root of pterygoid plate via lateral approach in cases of squamous cell carcinoma of maxillary sinus, the most common pathologic type, that has invaded the posterior wall into the infratemporal fossa. Desugn and methods: 28 cases of maxillary sinus squamous cell carcinoma patients, who surgically treated, were studied retrospectively. Results: The mean follow-up period was 78.8 months. We got the 2-year disease free survival rate and survival analysis curve. The 2-year disease free survival rate was 75% for both total and radical maxillectomy groups. All the resurrences occurred by 2 years after surgery. But, the recurrences of radical maxillectomy group occurred later than that of total maxillectomy group. Conclusions: In such cases of advanced maxillary sunus cancer patients as T4a patients especially with posterior wall destruction and infratemporal fossa invasion, radical maxillectomy is thought to be an effective treatment method.
