[en] Background: Leukocyte and platelet rich fibrin (L-PRF) is considered a biomaterial that can play an important role in wound healing and tissue repair / regeneration. Objective: This study focused on confirming the effectiveness of (L-PRF) compared to standard cures with nitrofurazone ointment on post-surgical bleeding, intensity of post-surgical pain, inflammation, infection, analgesic intake and healing period of the postoperative wound, in patients with bilateral onicocriptosis treated with chemical matricectomies with 88% phenol. Method: Twenty healthy patients between 18 and 65 years of age who presented bilateral onicocriptosis (n = 40) were selected and received both cures bilaterally, one in each Hallux of the patient. The interventions were performed in a clinic specialized in foot and ankle surgery. The two types of cures were randomized to each Hallux of the patient and thus 20 Hallux were established with cures with (L-PRF) (experimental group) and 20 Hallux with cures with nitrofurazone ointment (control group), so that each patient had received the Two types of cure. The patients were blinded, so they did not know that Hallux had received the different cure. Results: Statistically significant differences (p <0.001) were found between both groups in the postsurgical hemorrhage and in the wound healing period, showing a reduction in bleeding and days respectively with the priests with (L-PRF) compared with the nitrofurazone ointment cure. The rest of the variables did not show statistically significant differences (p> 0.05). Conclusions: (L-PRF) compared to standard cures with nitrofurazone poamada in chemical matricectomies with 88% phenol reduced the period of wound healing and bleeding after nail surgery. Therefore, FRPL can be considered a first-line adjuvant treatment for patients with nail problems that require surgical procedures.

[gl] Fondo: A fibrina de leucocitos rica en plaquetas (FRPL) é considerada un biomaterial que pode desempeñar un papel importante na curación de feridas e na reparación / rexeneración de tecidos. Obxectivo: Deste estudo centrouse en confirmar a eficacia da FRPL en comparación con curas estándar con pomada de nitrofurazono sobre hemorraxia postquirúrxica, intensidade de dor postquirúrxico, inflamación, infección, inxestión analxésica e período de curación de a ferida postoperatoria, en pacientes con onicocriptose bilateral tratados con matricectomías químicas cun 88% de fenol. Metodoloxía: Unha vintena de pacientes sans entre 18 e 65 anos foron seleccionados con onicocriptose bilateral (n = 40) e recibiron ambas as curas bilateralmente, unha en cada Hallux do paciente. As intervencións realizáronse nunha clínica especializada en cirurxía do pé e nocello. Os dous tipos de curas foron aleatorizados a cada Hallux do paciente e así se estableceron 20 Hallux con curas con FRPL (grupo experimental) e 20 Hallux con curas con pomada nitrofurazona (grupo control), de xeito que cada paciente recibira o Dous tipos de cura. Os pacientes estaban cegados, polo que non sabían que Hallux recibira a cura diferente. Resultados: atopáronse diferenzas estatísticamente significativas (p <0,001) entre ambos grupos no período de curación da hemorraxia e cirúrxica da ferida postguirúrxica, mostrando unha redución da hemorraxia e dos días respectivamente cos curas con FRPL en comparación coa cura de pomada. de nitrofurazono. O resto das variables non mostraron diferenzas estatisticamente significativas (p> 0,05). Conclusións: o FRPL reduciu o período de curación de feridas e hemorraxias despois da cirurxía das uñas en comparación coa cura estándar. Polo tanto, FRPL pode considerarse un tratamento adxuvante de primeira liña para pacientes con problemas de uñas que precisan procedementos cirúrxicos.
