目的:
下顎第3大臼歯の外科的除去術における舌神経損傷(LNI)の頻度と関連する危険因子を明らかにすること。
OBJECTIVE: To determine the frequency of lingual nerve injury (LNI) during the surgical removal of mandibular third molar and the associated risk factors.
研究デザイン:
記述的研究。研究場所および期間アユーブ教育病院口腔顎顔面外科、アボタバード、2021年1月~6月。
STUDY DESIGN: Descriptive study. Place and Duration of the Study: Department of Oral and Maxillofacial Surgery, Ayub Teaching Hospital, Abbottabad, from January to June 2021.
方法:
第三大臼歯内反症手術を受けた患者121名を対象とした。データは、問診によりプロフォーマで収集した。1週間後、1ヵ月後、3ヵ月後に追跡調査を行った。LNIの頻度、および様々な外科的処置ステップとの関連性が決定された。
METHODOLOGY: A total of 121 patients were included in this study who had undergone impacted third molar surgery. Data were collected on a proforma via interview. Patients were followed up after 1 week, 1 month, and 3 months of duration. Frequency of LNI and its association with various surgical procedure steps were determined.
結果:
本研究の結果、121例中、LNIの頻度は3.3%(n=4)であった。インパクションの種類(p=0.047)、舌側フラップの後退(p<0.001)、歯の分割(p=0.029)、および手術期間の長さが有意に関連していることが判明した。
RESULTS: This study shows that out of 121 patients, frequency of LNI was found to be 3.3% (n=4). The type of impaction (p=0.047), lingual flap retraction (p<0.001), tooth splitting (p=0.029), and longer duration of surgery were found to be significantly associated with it.
結論:
下顎有顎第三大臼歯手術におけるLNIの頻度は3.3%であり、水平埋伏、舌側フラップ後退、歯牙分割、および30分以上の手術時間と有意に関連していた。
CONCLUSION: The frequency of LNI during mandibular impacted third molar surgery was 3.3% in this study, and significantly associated with horizontal impaction, lingual flap retraction, tooth splitting, and duration of surgery longer than 30 minutes.
