概括
膜脊保护 (ARP) 有效地保持了后部脊高度,并在拔牙后减少了鼻气动化. 这种技术可能会减少对鼻增大手术的需要.
科学领域:
- 口腔和牙面部外科手术
- 牙周病学 牙周病学
- 牙科植入物学 牙科植入物学
背景情况:
- 膜脊维护 (ARP) 是一种手术程序,用于在拔牙后保持膜脊轮和体积.
- 后大抽取可以导致显著的脊柱高度减少和增加鼻气动化,使牙植入物放置复杂化.
- 当骨高度不足以使植入物稳定时,通常需要侧侧鼻腔增大.
研究的目的:
- 为了评估膜脊保护 (ARP) 在维持脊高度方面的有效性.
- 为了评估ARP对鼻肺炎的影响,在部后部进行提取后.
- 为了确定ARP是否减少了需要横侧鼻膜增大手术的需要.
主要方法:
- 一项随机对照试点研究,涉及28名大后部抽取和6-8毫米骨高度的患者.
- 站点被随机分配到无助口愈合 (控制),ARP与去蛋白牛骨矿物质 (DBBM) (试验1) 或原稳定DBBM (试验2).
- 术前和术后CT扫描在4个月后评估了脊的高度,鼻体积和需要鼻地面升高 (SFE).
主要成果:
- 与试验1 (0.9毫米) 和试验2 (1.0毫米) 组相比,对照组显示了显著的平均中山脊高度减少 (-2.7毫米).
- 在ARP组 (试验1和试验2) 中没有观察到有意义的中山脊高度变化.
- 对照组的鼻体积显著增加 (0.7厘米3),而测试1显示下降 (-0.7厘米3). 89%的对照患者需要SFE,而42.8% (试验1) 和40% (试验2).
结论:
- 膜脊保护 (ARP) 有效地减轻了提取后后尾垂直高度变化.
- ARP可能会减少鼻肺炎,从而可能减少对侵入性鼻增大手术的需求.
- DBBM和原稳定DBBM都对ARP显得有效,为传统的鼻提升提供了一个不那么侵入性的替代方案.

Alveoli and Alveolar Ducts
2.2K
The respiratory zone of the human body, which stands in contrast to the conducting zone, comprises the structures that actively participate in the exchange of gases. The initiation of this zone is marked by the terminal bronchioles converging into respiratory bronchioles, the tiniest bronchiole classification. The respiratory bronchioles give way to the alveolar ducts that opens into a congregation of alveoli. Actively involved in gas exchange, alveoli resemble tiny sacs similar to clusters of...

Suctioning the Nasopharyngeal Airway
316
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.
