ABSTRACT
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 percent and middle (63 percent) parts, whereas the inferior part (34 percent) was documented to receive the poorest arterial supply. The present study recognized anastomotic connections in 6 percent 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 percent of fetal cases, and (ii) between the ascending pharyngeal and recurrent pharyngeal arteries which terminated at the inferior part in 2 percent 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...
RESUMEN
Este estudio proporciona una descripción detallada de las arterias que irrigan el paladar blando a través de las arterias (i) palatina ascendente, (ii) tonsilar, (iii) faríngea ascendente, y (iv) palatinas menores. Se realizaron disecciones bilateralmente en 30 cabezas y cuellos de fetos y 20 de adultos (n = 100). Esta investigación documentó las arterias que terminaron en diferentes partes (superior, media e inferior) del paladar blando y demostró que la mayoría terminaba a nivel superior (83 por ciento) y medio (63 por ciento), mientras que la parte inferior (34 por ciento recibía un escaso suministro arterial. Se reconocieron conexiones anastomóticas en 6 por ciento 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 por ciento de los casos fetales, y (ii) entre las aa. faríngea ascendente y faríngea recurrente, que terminaban en la parte inferior en un 2 por ciento de las muestras fetales. La posición y las relaciones de las arterias del paladar blando es relevante para minimizar el riesgo de interrupción vascular y falla de los colgajos miomucosos o mucosos, durante la reparación de paladar hendido o en la corrección quirúrgica de insuficiencia velofaríngea...
