The palatal mucosa is a major donor site for connective tissue in the field of periodontal plastic surgery, since it satisfies both the esthetic and functional demands of patients. The purpose of this study was to use histomorphometric analysis to measure the thicknesses of the palatal mucosa and the lamina propria including the epithelium on cadavers.
Thirty-four hemimaxillae of cadavers were examined (13 male and 4 female, mean age 57.2 years). Each maxilla was processed for histological sectioning and subsequently for histomorphometric analysis. The thicknesses of the palatal mucosa and the lamina propria including the epithelium were measured at three points starting from the alveolar crest, at intervals of 4 mm, with the aid of Adobe Photoshop.
The thickness of the palatal mucosa at the alveolar crest and at 4 and 8 mm below the alveolar crest were 2.51 ± 0.83 (mean ± SD), 2.92 ± 0.80, and 3.62 ± 0.99 mm, respectively, and thus increasing from the alveolar crest toward the midpalatal suture. Conversely, the thicknesses of the lamina propria including the epithelium at these same positions were 2.06 ± 0.70, 1.54 ± 0.48, and 1.28 ± 0.46 mm, respectively, thus decreasing toward the midpalatal suture.
The present results indicate that clinicians need to be particularly careful when harvesting palatal mucosa that is destined to be used as autogenous donor material for connective tissue in periodontal plastic surgery.
在牙周整形手术领域，腭黏膜是结缔组织的主要供区，因为它能满足患者的美学和功能需求。本研究的目的是使用组织形态计量分析来测量尸体上腭黏膜和包括上皮的固有层的厚度。
检查了34例尸体的半侧上颌骨（男性13例，女性4例，平均年龄57.2岁）。对每个上颌骨进行组织切片处理，随后进行组织形态计量分析。借助Adobe Photoshop，从牙槽嵴开始，每隔4毫米在三个点测量腭黏膜和包括上皮的固有层的厚度。
牙槽嵴处以及牙槽嵴下方4毫米和8毫米处的腭黏膜厚度分别为2.51±0.83（平均值±标准差）、2.92±0.80和3.62±0.99毫米，因此从牙槽嵴向腭中缝增厚。相反，在这些相同位置包括上皮的固有层厚度分别为2.06±0.70、1.54±0.48和1.28±0.46毫米，因此向腭中缝变薄。
目前的结果表明，临床医生在采集打算用作牙周整形手术中结缔组织自体供体材料的腭黏膜时需要格外小心。
