Summary
Smartphone endoscope adapters enhance flexible nasolaryngoscopy by offering high diagnostic accuracy and improving resident education. These portable devices facilitate video recording and sharing, overcoming limitations of traditional endoscopy equipment.
Area of Science:
- Otolaryngology
- Medical Education
- Health Technology Assessment
Background:
- Flexible nasolaryngoscopy is crucial for otolaryngological exams.
- Traditional endoscopy towers limit video recording and sharing capabilities.
- Smartphone endoscope adapters offer improved mobility and recording flexibility.
Purpose of the Study:
- To review the literature on smartphone endoscope adapters' impact on patient care, satisfaction, and resident learning.
- To assess the diagnostic accuracy and video quality of smartphone-assisted nasolaryngoscopy.
- To evaluate the educational benefits of these adapters for residents.
Main Methods:
- Systematic literature review adhering to PRISMA guidelines.
- Searched Ovid MEDLINE, PubMed, and EMBASE for English language studies (1946-2017).
- Registered study protocol with PROSPERO database (CRD42018086714).
Main Results:
- Three studies were selected from 91 abstracts for full-text review.
- Smartphone adapter videos demonstrated high diagnostic accuracy and quality.
- Significant benefits were observed for resident education.
Conclusions:
- Smartphone endoscope adapters show high diagnostic accuracy and video quality for nasolaryngoscopy.
- These devices enhance resident education in otolaryngology.
- Despite limited data, adapters offer a promising, portable solution for endoscopic procedures.

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

15.2K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

13.4K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.

The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...

In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...
