まとめ
小児単面性慢性中耳炎 (COME) は空間的聴覚を著しく損なっており,耳鳴りのリスクを高めます. これらの中央聴覚的影響のために,一方的な COME の治療に関する現在のガイドラインは再評価する必要があるかもしれません.
科学分野:
- 小児聴覚科
- 耳鼻喉科
- 神経科学
背景:
- 慢性的な中耳炎 (COME) は子供に多く見られ,聴覚障害を引き起こす可能性があります.
- 現在のガイドラインでは,二国間のCOMEの治療を推奨しているが,一方的なCOMEの治療のみを推奨している.
- 単面的なCOMEは,バイナウラル処理の欠陥と,音声間の値の違いによる耳鳴りを引き起こす可能性があります.
研究 の 目的:
- 中央聴覚機能と耳鳴りに対する一方的な COME の影響を調査する.
- 聴覚処理を正常な聴覚,双面的な COME,および片面的な COMEで比較する.
- 片側 COME の治療勧告の潜在的な改訂を参考にする.
主な方法:
- 3つの小児科コホート:正常聴覚 (N=12),双面的なCOME (N=11) および単面的なCOME (N=7) を比較した前向きな横断的研究.
- マスキング (SRM) テストと耳鳴り音の高さ測定を用いた.
- 5. 4~13. 7歳の参加者は,COME群の劣悪な耳で比較可能な純音の値 (∼30 dB HL) を示した.
主要な成果:
- 単方面 COME コホートでは,対照群と比較してSRMの性能が著しく低下した (p=0. 012).
- マスキング効果による空間的解放の減少と相関するより大きな口腔間の値非対称性 (F=5.1,p=0.033).
- 耳鳴りの発生率は高かった.一方的なCOMEでは71%で,双方向的なCOMEでは55%で,気分や生活の質と関連していた.
結論:
- 小児の片面性 COME は,重要な中央聴覚処理の欠陥と耳鳴りに関連しています.
- 現行の治療ガイドラインは,片面的な COME の治療には不十分である可能性が示唆されています.
- これらの中央聴覚の影響を確認し,臨床実践の変更を導くために,さらなる縦断的な研究が必要である.

Tonsillitis I: Introduction

Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.

Anatomy of the Ear
8.9K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Auditory Pathway
5.8K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

Chronic Pharyngitis
4.8K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

The Auditory Ossicles
2.0K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...
