OBJECTIVE: To investigate the classification of alar base @entity308 , so as to provide the reference for the surgical management of secondary @entity85 of @entity3384 . METHODS: From Jul. 2008 to Feb. 2009, 26 cases with @entity85 of @entity3384 were treated. All the @entity1 underwent 3-dimensional CT for maxillary measurement. The nasal soft tissue measurement was performed pre- and post-operatively. The relationship between the maxillary and soft tissue at alar base was analyzed. The @entity85 was classified. RESULTS: The location of alar base was not related to the form of piriform aperture, but the bony defect at the alar base was correlated to the @entity1 satisfactory. The @entity85 was graded as I when the @entity308 at alar base was less than 4.5 mm in depth, as II when it was 4.5-5.0 mm in depth, and as III when it was more than 5 mm in depth. The deformity could be corrected with only soft tissue plasty for grade I, with soft tissue plasty or artificial implants for grade II, with combined bone autograft or @entity2419 repair for grade III. CONCLUSIONS: The @entity308 at maxillary does not necessarily result in alar base @entity308 . The alar base can be adjust to proper position through operation. The operation should be designed based on the preoperative nasal measurement.
