This study provides a detailed description of the arteries supplying the soft palate via: (i) ascending palatine; (ii) tonsillar; (iii) ascending pharyngeal; and (iv) lesser palatine arteries. Detailed dissections were performed on each side of thirty fetal and twenty adult head and neck specimens (n=100). This investigation documents the arteries terminating at the respective parts (superior, middle and inferior) of the soft palate and demonstrated that the majority of arteries terminated at the superior (83%) and middle (63%) parts, whereas the inferior part (34%) was documented to receive the poorest arterial supply. The present study recognized anastomotic connections in 6% of fetal specimens i.e. (i) between the ascending palatine and lesser palatine arteries which terminated at the superior part of the soft palate in 4% of fetal cases, and (ii) between the ascending pharyngeal and recurrent pharyngeal arteries which terminated at the inferior part in 2% of fetal specimens. The position and relations of the soft palate arteries is of significance to minimize the risk of vascular disruption and myomucosal or mucosal flap failure during cleft palate repair and for the surgical correction of velopharyngeal insufficiency. Este estudio proporciona una descripci車n detallada de las arterias que irrigan el paladar blando a trav谷s de las arterias: (i) palatina ascendente, (ii) tonsilar, (iii) far赤ngea ascendente, y (iv) palatinas menores. Se realizaron disecciones bilateralmente en 30 cabezas y cuellos de fetos y 20 de adultos (n = 100). Esta investigaci車n document車 las arterias que terminaron en diferentes partes (superior, media e inferior) del paladar blando y demostr車 que la mayor赤a terminaba a nivel superior (83%) y medio (63%), mientras que la parte inferior (34 %) recib赤a un escaso suministro arterial. Se reconocieron conexiones anastom車ticas en 6% de las muestras fetales, (i) entre las aa. palatinas ascendentes y las aa. palatinas menores, que terminaron en la parte superior del paladar blando en 4% de los casos fetales, y (ii) entre las aa. far赤ngea ascendente y far赤ngea recurrente, que terminaban en la parte inferior en un 2% de las muestras fetales. La posici車n y las relaciones de las arterias del paladar blando es relevante para minimizar el riesgo de interrupci車n vascular y falla de los colgajos miomucosos o mucosos, durante la reparaci車n de paladar hendido o en la correcci車n quir迆rgica de insuficiencia velofar赤ngea.
