Summary
Vocal fold augmentation using autologous fat injections is generally safe, but over-injection can occur, leading to voice issues. Complications like over-injection and granulomas are manageable with procedures such as lateral cordotomy and fat removal.
Area of Science:
- Otolaryngology
- Regenerative Medicine
- Voice Science
Background:
- Autologous fat (lipoinjection) is a common, biocompatible material for vocal fold augmentation.
- While widely used, the complication rate of lipoinjection for vocal fold augmentation requires further investigation.
Purpose of the Study:
- To evaluate the complication rate of autologous fat injections for vocal fold augmentation.
- To identify specific complications and their management outcomes.
Main Methods:
- Retrospective review of 98 vocal fold injections performed between 1997 and 2008.
- Data collected included patient demographics, diagnosis, procedure details, follow-up duration, and complications.
- Eighty-eight patients met the inclusion criteria for analysis.
Main Results:
- The most common indications were vocal fold paresis, scarring, and presbylaryngeus.
- Four laryngeal complications (4.5%) were observed: three over-injections (3.4%) and one granuloma (1.1%).
- Over-injections resulted in dysphonia but were successfully treated with cordotomy and fat removal, improving voice quality.
Conclusions:
- Autologous fat lipoinjection for vocal fold augmentation is a safe procedure.
- A risk of over-injection exists, potentially causing dysphonia.
- Complications such as over-injection can be effectively managed with lateral cordotomy and fat removal.

01:21Larynx
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

01:30Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
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 interventions are...
01:12Local Anesthetics: Adverse Effects
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

01:24Healing II: Complications
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
