Complications after mandibular third molar extraction.

抄録

下顎第3大臼歯抜歯後の術後合併症と、年齢、性別、手術適応、大臼歯の位置、手術経験、手術手技、術後ケアなどのパラメータとの関係の可能性を分析するために、1,797人の患者の記録をレトロスペクティブに調査した。高齢の患者ほど合併症に悩まされる傾向があった。また、臼歯周囲炎の徴候があるときに手術を行った場合にも、合併症が多くみられた。スタッフによる手術と研修医による手術の平均合併症発生率に統計学的有意差はなかった。再吸収性縫合糸の除去やその他の術後ケアのために、患者が日常的に再来院する理由はないと思われる。

The records of 1,797 patients were retrospectively examined to analyze the possible relationships between postoperative complications following mandibular third molar extraction and parameters such as age, sex, indication for surgery, position of the molar, surgical experience, surgical technique, and postoperative care. Older patients tended to suffer more often from complications. Surgery performed while there were signs of pericoronal inflammation also resulted in more complications. There was no statistically significant difference in the mean complication rate arising from surgery performed by staff members and the rate when surgery was performed by residents. There seems to be no reason for patients to return routinely for removal of resorbable sutures or other postoperative care because this practice does not result in a decrease in postoperative symptoms.
