Reverse Pedicle U-Shaped Palatal Flap: An Innovative Technique for Repair of Severe Caudal Palatal Defects in Two Dogs

“…However, it is not always possible to trace the primary cause making a histological examination crucial to rule out pathologic conditions such as immune-mediated disease or neoplasia in which the surgical treatment should be carefully considered or would even be contraindicated in selected cases. 41–43…”

“…However, it is not always possible to trace the primary cause making a histological examination crucial to rule out pathologic conditions such as immune-mediated disease or neoplasia in which the surgical treatment should be carefully considered or would even be contraindicated in selected cases. [41][42][43] This article describes two dogs with chronic acquired palatal defects secondary to foreign bodies trapped between the right and left maxillary teeth.…”

“…53 Many different techniques to repair palatal defects are described including local mucosal flaps, axial pattern flaps, tongue flaps, auricular cartilage-free grafts, and artificial obturators. 18,[30][31][32][34][35][36][37][38][39][40][41]54,55 However, these defects, mostly the acquired ones, could have different shapes, locations, and dimensions making in some cases already existing techniques unfeasible. Even flaps from the vestibular mucosa could have been risky in these two dogs since the palatal defects were transversely wide and they extended minimally rostro-distally requiring long, narrow flaps.…”

Evaluation of the superior and inferior labial musculomucosal flaps in cats: An angiographic study and case series

“…In both congenital and acquired defects, there is typically little surrounding tissue available for reconstruction, poor or damaged vascularity, relatively immobile tissues, localized infection of the tissues due to the chronic communication of the oral and nasal cavities, and constant mechanical stresses on the repair from respiration, mastication, and deglutition 2–4 . These hurdles have prompted the development of numerous techniques for repair of palatal defects, including: direct appositional closure, 5 single‐layer vestibular flaps, 1,5–11 mucoperiosteal rotation or transposition flaps, 1,5,6,9,11 double‐layer flaps, 1,5–8,11,12 overlapping flap technique, 5,11,13 bilateral vestibular mucosal overlapping flaps, 6,11,14 medially repositioned double flap (von Langenbeck technique), 1,5,9,11,13 split palatal U‐flap, 1,6,11,15 palatal island flaps, 16,17 myoperitoneal microvascular free flaps, 18 auricular cartilage grafts, 2,3,19 prosthetic obturators 20,21 and tongue flaps 22 …”
