A Study of Clinical Classification for Maxillectomy

Objective To evaluate the significance of clinical classification for maxillectomy.Methods 274 cases with several kinds of tumors involving the maxilla region were treated and their treatment,histo pathological diagnosis were reviewed retrospectively.According to the primary sites and regions of the tumors,maxillectomy were grouped into Ⅰ,Ⅱ,Ⅲ, and Ⅳ classes clinically for separate treatment and effective results′ evaluation.Results Among the 274 cases,Class Ⅰ maxillectomy was performed in 161 Ccases,Class Ⅱ in 58 cases,Class Ⅲ in 34 cases and Class Ⅳ in 21 cases.18 cases with Class Ⅲ or Class Ⅳ maxillectomy performed were followed with a radical neck dissection (15 cases) or orbital exenteration (3 cases) simultaneously.Conclusion Clinical classification of maxillectomy into Ⅰ,Ⅱ,Ⅲ, and Ⅳ classes is useful and easy, which is clear to demonstrate the removed maxilla region.It is also effective for evaluation of the treatment results.
