目的:

外科的フラップなしで抜歯した衝撃下顎第三大臼歯の効果を評価する。

PURPOSE: To evaluate the effect of impacted mandibular third molars extracted without surgical flaps.

方法:

下顎第三大臼歯に衝撃を受けた患者98名を収集した。合計112歯を非外科的フラップ群と外科的フラップ群に分けた。非外科的フラップ群では切除法またはT字切断法で歯を切除し，外科的フラップ群では三角形のフラップを設計した．術後1日後、3日後、1週間後の術後合併症を記録し、SPSS 17.0ソフトウェアパッケージを用いて統計解析を行った。

METHODS: Ninety-eight patients with impacted mandibular third molars were collected. A total of 112 teeth were divided into non-surgical flap group and surgical flap group. In non-surgical flap group, the teeth were removed by transection method or T-shaped truncation method, and triangular flaps were designed in the surgical flap group. Postoperative complications at 1 day, 3 days, and 1 week after operation were recorded, and statistical analysis was performed using SPSS 17.0 software package.

結果:

術後1日目と3日目の出血、腫脹、疼痛、開口制限、日常生活への影響などの合併症は、非手術フラップ群の方が手術フラップ群に比べて有意に低かった(P<0.05)。

RESULTS: Complications such as hemorrhage, swelling, pain, mouth opening limitation and impact on daily life at postoperative 1 day and 3 day in non-surgical flap group were significantly lower than in surgical flap group (P<0.05).There was no significant difference in average operation time between the two groups (P>0.05).

結論:

下顎第三大臼歯衝撃部を外科的フラップなしで除去することができます。術後の合併症を軽減し、患者さんのQOLを向上させることができます。

CONCLUSIONS: Impacted mandibular third molar can be removed without surgical flaps in selected patients. It helps alleviate patients'postoperative complications and improve their quality of life.
