topographical relationship of the Greater Palatine Artery and the palatal spine significance for periodontal surgery
Journal of Clinical Periodontology, 2014Co-Authors: Myounghwa Lee, Byung Sun Park, Yong Hyun Jeon, Yoon Young Chung, Heungjoong KimAbstract:Aim The aims of this study were to (1) identify the branching pattern and course of the Greater Palatine Artery (GPA), (2) carry out a morphological analysis of the palatal bony prominence that divides the medial and lateral grooves and (3) characterize the topographical relationships between these two structures. Methods Thirty-six hemimaxillae were studied with the aid of a surgical microscope to elucidate the GPA. A further 25 dry skulls were examined to establish the morphology of the palatal spine. Results The most common GPA branching pattern was type I (41.7%, 15 sides), which gave off the medial and canine branches after the bony prominence. The distances from the CEJ to the lateral branch of the GPA were 9.04 ± 2.93 mm (canine), 11.12 ± 1.89 mm (first premolar), 13.51 ± 2.08 mm (second premolar), 13.76 ± 2.86 mm (first molar) and 13.91 ± 2.20 mm (second molar). The palatal spine was frequently observed as the bony prominence (66.3%, 57 sides), and was located at 6.49 ± 1.76 mm from the Greater Palatine foramen, with a length of 10.42 ± 2.45 mm. There was no a correlation between the bony prominence shape and the GPA branching pattern. Conclusions These results could provide the reference data regarding the topography of the GPA for periodontal surgery.

histological assessment of the palatal mucosa and Greater Palatine Artery with reference to subepithelial connective tissue grafting
Anatomy & Cell Biology, 2013Co-Authors: Kwanghee Cho, Myounghwa Lee, Dongseol Lee, Heungjoong KimAbstract:This study aimed to measure the thickness of the epithelium and lamina propria of the palatal mucosa and to elucidate the location of the Greater Palatine Artery to provide the anatomical basis for subepithelial connective tissue grafting. Thirty-two maxillary specimens, taken from the canine distal area to the first molar distal area, were embedded in paraffin and stained with hematoxylin-eosin. The thickness of the epithelium and lamina propria of the palatal mucosa was measured at three positions on these specimens, starting from 3 mm below the alveolar crest and in 3-mm intervals. The location of the Greater Palatine Artery was evaluated by using image-processing software. The mean epithelial thickness decreased significantly in the posterior teeth; it was 0.41, 0.36, 0.32, and 0.30 mm in the canine, first premolar, second premolar, and first molar distal areas, respectively. The lamina propria was significantly thicker in the canine distal; it was 1.36, 1.08, 1.09, and 1.05 mm, respectively. The mean length from the alveolar crest to the Greater Palatine Artery increased toward the posterior molar; it was 7.76, 9.21, 10.93, and 11.28 mm, respectively. The mean depth from the surface of the palatal mucosa to the Greater Palatine Artery decreased from the canine distal to the first premolar distal but increased again toward the posterior molar; it was 3.97, 3.09, 3.58, and 5.50 mm, respectively. Detailed histological assessments of the lamina propria of the palatal mucosa and the Greater Palatine Artery are expected to provide useful anatomical guidelines for subepithelial connective tissue grafting.

Endoscopic endonasal Greater Palatine Artery cauterization at the incisive foramen for control of anterior epistaxis.
The Laryngoscope, 2015Co-Authors: Anna Butrymowicz, Adam Weisstuch, Alice Zhao, Jay Agarwal, Carlos D. Pinheiro-netoAbstract:OBJECTIVES/HYPOTHESIS To describe the anatomy of the incisive foramen and the transnasal endoscopic approach to the Greater Palatine Artery at this foramen, and to evaluate the importance of the Greater Palatine Artery as a cause of recurrent anterior epistaxis. STUDY DESIGN Anatomical dissection, radiographic study, and prospective case series. SETTING Academic Medical Center. METHODS Sixty-nine computed tomography scans were reviewed, and measurements were made of the incisive foramina's distance to the anterior nasal spine and subnasale. Twenty-two cadavers had sagittal split craniotomies performed prior to the measurements. The distance from the anterior nasal spine to the incisive foramen was documented. We also present an illustrative case series of patients who underwent endoscopic cautery of the Greater Palatine Artery at the incisive foramen. RESULTS Radiographic review of the incisive foramen revealed a mean anterior nasal spine to incisive foramen distance on the right and left of 7.9 and 8.1 mm, respectively. The mean distance from the subnasale to incisive foramen on the right and left were 24.7 and 24.9 mm, respectively. CONCLUSIONS Endoscopic cauterization of the Greater Palatine Artery at the incisive foramen is a safe and effective method to control recurrent anterior epistaxis. The incisive foramen can be predictively found within 1 cm of the anterior nasal spine. Our case series corroborates the above. LEVEL OF EVIDENCE 4. Laryngoscope, 126:1033-1038, 2016.

connective tissue graft for gingival recession treatment assessment of the maximum graft dimensions at the palatal vault as a donor site
Journal of Periodontology, 2006Co-Authors: Virginie Monnetcorti, Alain Santini, Jeanmarc Glise, Caroline Fouquederuelle, Francoislaurent Dillier, Mariefranccoise Liebart, Alain BorghettiAbstract:Background: The palatal masticatory mucosa is widely used as a connective tissue donor site in gingival recession treatment. However, concern has been raised regarding the potential risk of damaging the Greater Palatine Artery (GPA) due to anatomical variations in the palatal vault. The anatomy of the palatal vault in terms of size and shape may affect the maximum dimensions of the graft that can be safely taken from the palatal vault. In a cohort of patients free of periodontal disease, the purpose of this study was to assess the maximum dimensions of the graft, particularly the height and length, that could be safely taken from the palatal vault.Methods: Plaster impressions were made from 198 patients free of periodontal disease. Because the connective tissue graft is usually taken from an area extending from the mid-palatal aspect of the canine to the mid-palatal aspect of the second molar, this interval was measured and represented the maximum length dimension. The emergence of the GPA was assumed to ...
