[Management in squamous cell carcinoma of maxillary sinus with orbital invasion].

OBJECTIVE

To explore the orbital management in advanced squamous cell carcinoma of maxillary sinus with orbital invasion.

METHOD: Forty-six postoperative cases of advanced squamous cell carcinoma of maxillary sinus with orbital invasion were followed up. Two,three,five-year survival rates and 2-year recurrence rates were analysed in,orbital bone invaded group, periorbit invaded group and orbital content invaded group.

RESULT: Two, three,five-year survival rates and 2-year recurrence rates were 65.2%, 55.6%, 46.7% and 38.1% in orbital bone invaded group; 57.1%, 50.0%, 45.5% and 53.8% in periorbit invaded group; 44. 4%, 37. 5%, 37. 5% and 62. 5% in orbital content invaded group, respectively. Survival rates of three groups descended and recurrence rates of three groups ascended but without statistical significance( P >0. 05).

CONCLUSION

During the surgery for advanced squamous cell carcinoma of maxillary sinus with orbital invasion without the evidence of optical nerve and eye ball involvement, preservation of orbital contents is considerable even though the orbital bone and periorbit are involved by the tumor.
