A Propeller Flap for Single-Stage Nose Reconstruction in Selected Patients: Supratrochlear Artery Axial Propeller Flap
2014
The paramedian forehead flap is the gold standard technique for nose reconstruction. It requires two different surgical operations which prolonged the postoperative dressing and care. We present our 5-year experience with a propeller flap based on the supratrochlear artery, which allows one-stage transfer of the forehead skin to the nose without the need for pedicle division. This technique is indicated in a selected group of patients who are not suitable for multiple-stage reconstructions because they have concurrent medical conditions, reduced mobility, or live far away from specialized medical centers. We have renamed this procedure as supratrochlear artery axial propeller flap, from the…
Transcranial direct current stimulation improves isometric time to exhaustion of the knee extensors
2016
International audience; Transcranial direct current stimulation (tDCS) can increase cortical excitability of a targeted brain area, which may affect endurance exercise performance. However, optimal electrode placement for tDCS remains unclear. We tested the effect of two different tDCS electrode montages for improving exercise performance. Nine subjects underwent a control (CON), placebo (SHAM) and two different tDCS montage sessions in a randomized design. In one tDCS session, the anodal electrode was placed over the left motor cortex and the cathodal on contralateral forehead (HEAD), while for the other montage the anodal electrode was placed over the left motor cortex and cathodal electr…
Forehead Patch Size Predicts the Outcome of Male–Male Competition in the Pied Flycatcher
2013
Males of many animal species express ornaments that affect their reproduction opportunities through male–male competition or female mate choice. Such ornaments can, for example, inform conspecifics about the fighting ability, condition or territory ownership of the bearer. Pied flycatcher (Ficedula hypoleuca) males have a conspicuous white forehead patch that varies greatly in size. We examined whether the white forehead patch is an intrasexually selected trait in a Finnish population. We artificially manipulated forehead patch size to represent two naturally occurring extremes and competed males against each other in the presence of a female. Males with a large forehead patch were more agg…
Expanded forehead (Fricke) flap for large defect of lateral canthal area
1993
The use of an expanded forehead (Fricke) flap to repair large full thickness defects of the lateral canthus and/or of the upper eyelid is presented. The reconstruction is performed in two stages. In the first stage, a rectangular, 25 ml tissue expander (6 cm in width and 2 cm in length) is inserted under the skin lateral to and above the eyebrow; expansion is completed in about three weeks. At the second stage, the lesion is excised, and the laterally based expanded flap is elevated. Using the expanded Fricke flap, thinner, abundant skin is obtained, and the donor site is directly closed, without grafting and without distorting the eyebrow. If there is a shortage of conjunctiva, this can be…
