目的:
本研究の目的は、神経感覚障害(NSD)と作成された両側矢状骨分割骨切り術(BSSO)の異なるタイプの舌骨骨折との関係を評価することであった。
OBJECTIVE: The aim of this study was to evaluate the relationship between neurosensory disturbance (NSD) and the different types of bilateral sagittal split osteotomy (BSSO) lingual fracture created.
研究デザイン:
研究グループは下顎変形症患者45名(90側、男性14名、女性31名)で構成された。CTスキャンは術前と術後1週間に実施した。すべての患者は術後のスキャン結果に基づいて舌側骨折ライン群に分類された。NSDは、術前と術後1、3、12ヶ月間に、感覚触覚Semmes-Weinstein(SW)テストと2点識別(TPD)テストを用いて検査した。
STUDY DESIGN: The study group consisted of 45 patients with mandibular deformities (90 sides; 14 males and 31 females). Computed tomography (CT) scans were obtained preoperatively and 1 week postoperatively. All patients were divided into lingual fracture line groups on the basis of their postoperative scans. NSD was tested preoperatively and 1, 3, and 12 months postoperatively by using a sensory touch Semmes-Weinstein (SW) test and the 2-point discrimination (TPD) test.
結果:
下顎BSSO後の舌側骨折線を基準に2群に分け、45名のうち39側(43.3%)が短裂、51側(56.7%)が長裂であった。短裂群はすべての試験で影響が少なく、術後1ヶ月のTPD試験では2群間の差は有意であったが、それ以外の期間では両試験では有意ではなかった。
RESULTS: Patients were divided into 2 groups on the basis of their lingual fracture lines after mandibular BSSO; among the 45 patients, 39 sides (43.3%) had short-splits, and 51 sides (56.7%) had long-splits. The short-split group was less affected at all tested times, and the difference between the 2 groups was significant 1 month postoperatively on TPD test but not at other times on the both tests.
結論:
分割型は術後3ヶ月および12ヶ月時のNSD発症率に影響を与えなかった。
CONCLUSIONS: The split type did not affect the NSD incidence at 3 and 12 months postoperatively.
