まとめ
脊髄下骨解剖は,レ・フォート・I骨解剖 (LFIO) の変形であり,従来のLFIOと比較して,アラーベースの拡大と上唇の延長が少ない. このテクニックは,整形外科手術中に鼻唇の構造をより良く保ちます.
科学分野:
- 口腔・口腔外科
- 整形外科
- 頭蓋骨と顔の解剖学
背景:
- ル・フォート・イ・オステオトミー (Le Fort I osteotomy, LFIO) は,望ましくない鼻唇の変化を引き起こす可能性があります.
- 脊髄下骨切除は,周周構造を保存し,これらの変化を最小限に抑えることを目的とした改造技術です.
研究 の 目的:
- ナソラビアル軟組織の変化に対する従来のLFIOと脊髄下LFIOの効果を比較する.
- 2つの外科的手法の間の耳根の幅,上唇の寸法,鼻唇角の違いを評価する.
主な方法:
- 従来のまたは脊髄下LFIOを受けた96人の患者による遡及コホート研究 (2019-2023年).
- 術前と術後で測定された,インターアラル幅,アラルベース幅,上唇の寸法,ナソラビアル角度が含まれていた.
- 統計的分析には,記述的統計,グループ比較,および相関/回帰分析が含まれていた.
主要な成果:
- 従来のLFIO (1. 85mm) よりも,アラーベースの幅が著しく小さかった.
- 従来のLFIOは,脊髄下LFIO (0. 3mm) に比べて,上唇の伸びが著しく増加しました.
- グループ間では,鼻口間幅や鼻口口角の有意な差異は認められなかった.
結論:
- 従来のLFIOと比較して,下脊椎骨解剖は,アラ基の拡大と上唇の延長を減少させています.
- これは,下脊椎骨解剖が鼻美学をより良く保存することを示唆しています.
- LFIO後に軟組織の変化を最小限に抑えようとする患者にとって貴重な代替手段として,この発見は脊髄下骨解剖を支持する.

Local Anesthetics: Chemistry and Structure-Activity Relationship
7.2K
Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...

Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...

Local Anesthetics: Clinical Application as Spinal Anesthesia
2.0K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
2.0K
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
