まとめ
この研究は,子供における状シヌス拡張の新分類を導入し,状骨のプロセスへの拡散を詳細に説明しています. 双面的な拡張は一方的なものに比べてより一般的です.
科学分野:
- アナトミー
- 放射線科
- 小児画像検査
背景:
- スフェノイドシヌスの解剖学は高度に変化し,周囲の骨構造に多様な拡張をもたらします.
- 現存する文献では,これらのスフェノイドシヌス拡張の標準化された分類が欠けている.
- この多様性は,外科的アプローチと鼻腔病理の理解に影響します.
研究 の 目的:
- スフェノイドシナスの拡張をスフェノイド骨のプロセスに新しい分類システムを開発し,提示する.
- 特定の解剖学的な特徴とパターンに基づいて これらの拡張を分類する.
- 子供の肺炎を記述するための標準化された枠組みを提供すること.
主な方法:
- 432人の子供 (出生から18歳まで) の頭部CTスキャンを遡及的に分析した.
- 3つのタイプの分類を提案した (タイプI:小翼,タイプII:大翼,タイプIII:型プロセス).
- 重要な解剖学的構造 (光学管,回転孔,状管) との関係に基づいて,各種の3つのサブタイプが定義されています.
主要な成果:
- 肺化率:小さな翼 (19.44%),大きな翼 (36.11%),ペトリゴイドプロセス (25.00%).
- 3つのタイプ (I,II,III) の双方向性肺炎は,片方性肺炎よりも頻繁であった.
- 稀なサブタイプ (Ia,Ic,IIa,IIc,IIIb) は,より一般的に一方的に観察されました.
結論:
- 著者は,スフェノイドシヌス拡張をスフェノイド骨のプロセスに新しい詳細な分類を提示しています.
- この分類は,小児の肺炎を評価するための標準化された方法を提供します.
- この研究は,子供における異なる状鼻腔拡張型と亜型の有病率とパターンを強調しています.

Cranial Bones: Lateral View
2.6K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Nose and Nasal Cavity
4.5K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Anatomy of Respiratory System I: Upper Respiratory Tract
2.5K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract....

Bone Markings
6.1K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

Anatomy of the Brain: Ventricles
5.1K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

Cranial and Spinal Meninges
1.7K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...
