Summary
Injection laryngoplasty for hoarseness shows similar voice outcomes whether performed in the office or operating room. This systematic review assists otolaryngologists in patient counseling regarding the optimal setting for this vocal fold immobility treatment.
Area of Science:
- Otolaryngology
- Speech Science
- Medical Procedure Outcomes
Background:
- Hoarseness is a common complaint impacting quality of life.
- Injection laryngoplasty is a treatment for vocal fold immobility.
- The optimal setting (office vs. operating room) for this procedure requires clarification.
Purpose of the Study:
- To compare voice outcomes of in-office versus in-operating room injection laryngoplasty.
- To aid otolaryngologists in counseling patients on procedure setting selection.
Main Methods:
- Systematic review adhering to PRISMA standards.
- Searched Cochrane, CINAHL, PubMed, and EMBASE for comparative studies.
- Assessed 4 observational studies using MINORS criteria; meta-analysis of 3 studies.
Main Results:
- All included studies reported voice improvement post-injection laryngoplasty.
- No significant difference in voice outcomes between office and operating room settings (P = .42 to .88).
- Meta-analysis confirmed no statistically significant difference in Voice Handicap Index-10 scores (SMD -0.11, P = .441).
Conclusions:
- Postprocedure voice outcomes for injection laryngoplasty are comparable regardless of setting.
- Meaningful clinical differences in voice outcomes between office and operating room procedures are unlikely.
- Findings support informed patient-physician decision-making regarding procedure location.

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
1.5K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
760
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
1.4K
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

2.1K
Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...

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...
