まとめ
重度のトラウマの後,の解剖を復元することは,伝統的な参考文献なしで困難です. 統計形状モデル (MAGIC-SSM) は,複雑な下の再建における診断と計画のための新しい解決策を提供します.
科学分野:
- 口腔および面外科手術
- バイオメディカルエンジニアリング
- メディカルイマージング (医学イメージング)
背景:
- 複雑なトラウマ後の下の解剖を復元することは,歯の閉塞や下の連続性などの従来の参照の喪失のために困難です.
- 重度の外傷後の変形は,しばしば,正確な外科計画と再建のための十分なランドマークがない.
- 解剖学的および閉塞的参照が損なわれる場合,既存の方法は困難になり,代替アプローチが必要になります.
研究 の 目的:
- マンディブラー統計形状モデル (MAGIC-SSM) の臨床応用を,代替解剖学的参照として記述する.
- MAGIC-SSMの診断,仮想計画,および重度の外傷後の下の変形に対する術後の評価における有用性を評価する.
- 従来のランドマークがない場合,下の再構築を導くために人口ベースの幾何学を使用する可能性を実証する.
主な方法:
- 標準的な人口データセットから派生したオープンソースの3D統計形状モデルであるMAGIC-SSMを使用しました.
- MAGIC-SSMを重度の外傷後の下の変形を伴う3つの臨床症例の基準調整に適用しました.
- 指示された場合,手術後の結果の定量的な評価のための雇用された距離マッピング.
主要な成果:
- MAGIC-SSMは,外科的な意思決定のための貴重な追加の解剖学的参照を提供しました.
- このモデルは,二次矯正,患者特有のインプラントによるハイブリッド再構築,および手術後の定量評価をサポートしました.
- モデルからの集団ベースの幾何学は,下の形状と対称性を回復するのに役立ちました.
結論:
- MAGIC-SSMは,従来のガイドが失われたときに,複雑な下のトラウマの再建のための実現可能な解剖学的枠組みを提供します.
- この統計形状モデルは,失われた空間的参照を人口ベースの幾何学に置き換えることで,下の形状と対称性を回復するのに役立ちます.
- 臨床医による MAGIC-SSM アプリケーションの再現性と信頼性を確立するために,さらなる検証が必要である.

Restorative Care

Restorative care is provided once a patient has been discharged from a healthcare facility and requires additional services. The additional services include home care, rehabilitation programs, and extended care. Restorative care centers help the patient regain their previous level of functioning or acquire a new level of functioning due to the incapacitating effects of a disease or a disability. It aims to assist patients in enhancing their quality of life by encouraging independence,...

Statistical Significance
22.3K
Once data is collected from both the experimental and the control groups, a statistical analysis is conducted to find out if there are meaningful differences between the two groups. A statistical analysis determines how likely any difference found is due to chance (and thus not meaningful). In psychology, group differences are considered meaningful, or significant, if the odds that these differences occurred by chance alone are 5 percent or less. Stated another way, if we repeated this...

Clinical Applications of Epidermal Stem Cells
3.3K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Local Anesthetics: Clinical Application as Spinal Anesthesia
1.5K
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
785
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...
