Summary
Open rhinoplasty impacts voice quality, altering acoustic parameters like frequency, amplitude, and bandwidth for both vowels and consonants. These voice changes were observed up to 10 months post-surgery.
Area of Science:
- Otolaryngology
- Acoustic analysis
- Speech science
Background:
- Voice changes can occur following interventions in the upper airway.
- Open rhinoplasty is a surgical procedure that involves manipulation of the upper airway.
Purpose of the Study:
- To evaluate the effects of open rhinoplasty on voice quality.
- To investigate changes in acoustic parameters after open rhinoplasty.
Main Methods:
- Cross-sectional study involving 25 patients undergoing open rhinoplasty.
- Acoustic parameters (frequency, bandwidth, amplitude) measured before and 3, 7, 10 months after surgery.
- Analysis of sounds produced during pronunciation of vowels (A) and consonants (M, N).
Main Results:
- Vowel (A) pronunciation showed decreased amplitude and bandwidth, with increased frequency post-rhinoplasty.
- Consonant (M, N) pronunciation exhibited decreased amplitude, but increased bandwidth and frequency after surgery.
- Significant alterations in acoustic parameters were noted during the 10-month follow-up period.
Conclusions:
- Open rhinoplasty appears to influence voice quality.
- The surgical procedure leads to measurable changes in vocal frequency, amplitude, and bandwidth.
- These voice modifications persist for up to 10 months following open rhinoplasty.

01:30Alterations in Respiration II
1.8K
There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...

Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.

Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...

In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
