Trends in Utilization of Vocal Fold Injection Procedures
1Department of Otolaryngology, University of Miami Miller School of Medicine, Miami, Florida, USA drosow@med.miami.edu.
Summary
Vocal fold injections are increasingly popular. However, data shows operative injections, not office-based ones, significantly increased from 2000-2012, contrary to trends.
Area of Science:
- Otolaryngology
- Medical Procedure Analysis
Background:
- Office-based vocal fold injections have gained popularity.
- Previous trends suggested a shift towards minimally invasive, office-based procedures.
Purpose of the Study:
- To examine trends in procedure coding for vocal fold injections in the US from 2000 to 2012.
- To determine if coding reflects the perceived shift towards office-based procedures.
Main Methods:
- Analysis of the US Part B Medicare claims database.
- Querying Current Procedural Terminology (CPT) codes for vocal fold injections and related procedures between 2000 and 2012.
Main Results:
- Nonoperative laryngoscopic injections (CPT 31513, 31570) and operative medialization laryngoplasties (CPT 31588) remained constant.
- Operative vocal fold injection (CPT 31571) showed significant linear growth, increasing over 640% from 744 procedures in 2000 to 4788 in 2012.
Conclusions:
- The rise in CPT code 31571 indicates a growing proportion of vocal fold injections are performed in operating rooms.
- This trend contrasts with the expected increase in awake, office-based injection procedures.

823
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

1.2K
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx...
