Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The basic principle of a lobed or finger-like transposition flap is that, after covering the defect with the transposed tissue, the donor site is closed primarily. With large defects, a second lobe may be added to the flap if primary closure of the area left by the first lobe is not possible. The flap can often be made to adapt to the defect, but this maneuver, in combination with primary closure of the adjacent tissue, can sometimes produce excessive tension and compromise the blood supply. We present a series of 4 patients with epithelial tumors of the lateral wall of the nose. The defects left by surgical excision were covered by finger-like transposition flaps. Subcutaneous sutures called guitar-string sutures were used to reduce the size of the defect and facilitate tension-free closure. We propose use of the guitar-string subcutaneous suture in those cases in which the defect is larger than the area that can be covered by the flap. This will make it easier to adapt the flap to the defect and will reduce the risk of excessive tension causing necrosis of the transposed tissue. El principio básico de un colgajo lobulado o digitiforme de trasposición es que una vez que el tejido desplazado cubra el defecto, la zona dadora cierre directamente. Cuando los defectos son grandes puede ser necesaria la realización de un segundo lóbulo, debido a que el área que deja el primer lóbulo con su movimiento no cumple el criterio anterior. Con frecuencia se puede forzar el colgajo y adaptarlo al nuevo lecho, aunque a veces esta maniobra, sumada al cierre directo del tejido adyacente, puede traccionar en exceso y comprometer la vascularización. Se presenta una serie de 4 pacientes con tumores epiteliales en el lateral nasal. Tras la extirpación quirúrgica, los defectos resultantes se cubrieron mediante colgajos digitiformes de trasposición. En el diseño del cierre de los defectos se utilizaron unos puntos de sutura subcutáneos denominados en «cuerda de guitarra» para disminuir el tamaño del área cruenta y facilitar el ensamblaje del colgajo sin tensión. Proponemos la realización de la sutura subcutánea en «cuerda de guitarra» para aquellos casos en los que el defecto cutáneo es mayor que la cobertura que aporta el colgajo local, con el objetivo de facilitar su ensamblaje y disminuir el riesgo de necrosis del tejido desplazado por una excesiva tensión.
