The Sliding Technique: A Method to Treat the Overprojected Nasal Tip

BACKGROUND: This report aims to demonstrate the advantages of the sliding technique for reducing an overprojected tip. METHODS: In this study 271 patients (201 females, 70 males) were treated using this technique. It was used for isolated tip hypertrophy (N = 93) and combined deformities (N = 147). RESULTS: A medial sliding was performed in 109 patients, a lateral in 125 patients, and a combined lateral and medial sliding was used in 9 patients. Twenty patients needed additional skin resection at the columella. Follow-up of our first 80 patients showed an average reduction of around 11%. Only one patient of 80 in this study had to be revised. CONCLUSION: The sliding technique is safe and reliable as well as a logical and effective technique to deproject the nasal tip.     

BAX: A Toolbox for the Dynamic Analysis of Functional MRI Datasets

We developed a toolbox called BAX (brain activation explorer) for the dynamic analysis of functional magnetic resonance imaging (fMRI) datasets using the general linear model. The toolbox provides a graphical user interface where several routines can be accessed to extract different sets of information from a given series of functional images. The dynamic analysis can be implemented using either an incremental approach or a sliding window approach. In particular, BAX can be used to construct dynamic activation maps that can be used to assess the contribution of newly added volumes in the final activation map, detect problematic segments in the dataset, or localize in time dynamic changes in brain activity. Consistency maps, which graphically represent the number of times voxels are consecutively detected as active in a given analysis, can also be constructed using either incremental or sliding window analysis. BAX runs under Matlab (MathWorks, Inc.) and requires some routines from SPM2 (Wellcome Department of Cognitive Neurology, London, UK) for its operation. It can be freely downloaded at website.
