The larynx is the medical term for the upper windpipe where the voice box and vocal cords are situated. Micro laryngeal surgery, otherwise known as micro laryngoscopy, is a minimally invasive surgical procedure used to operate on the larynx, usually performed on an outpatient basis. It is the most precise means of visualising the vocal cords. This procedure helps to perform a biopsy or remove abnormal growths, or cysts, such as granulomas or benign cysts, in the larynx. Patients who undergo micro laryngeal surgery have a probability of recovering faster than those who undergo traditional laryngeal surgery, and they also have a superior outcome in terms of voice quality. All of the surgery is performed with the help of a laryngoscope, which is an instrument inserted through the mouth. This instrument does not require an incision to be made on the skin.
At CARE Hospitals, our multidisciplinary staff consisting of medical specialists, surgeons, and care providers offer comprehensive diagnosis following international standards and protocols, minimally invasive treatments using state-of-the-art, latest technology, and post-operative care for quicker recovery, shorter hospital stays, and improvement of overall general health.
Causes and diagnosis
Acute trauma or chronic irritation to the larynx may cause changes in the vocal cords that may lead to polyps, nodules, and granulomas. All polyps, modules, and granulomas cause hoarseness of voice and the development of a breathy voice.
Diagnosis of polyps, nodules and granulomas in the larynx is based on direct or indirect visualisation of the larynx with the help of a mirror or laryngoscope. Microlaryngoscopy is used to perform a biopsy of a particular lesion to exclude carcinoma.
What is micro laryngeal surgery used for?
Micro laryngeal surgery is used in the evaluation and removal of various lesions of the vocal cords, including (but not limited to) cysts, polyps, papilloma, cancer, and Reinke's oedema.
When to undergo micro laryngeal surgery?
The goal of performing micro laryngoscopy is to obtain visual exposure of the throat region covering the larynx and pharynx for surgical examination, diagnosis, and treatment. Clinical indications for micro laryngoscopy may inform preoperative assessment and anaesthetic planning.
At CARE Hospitals, state-of-the-art diagnostic services using the latest technology and following the international standard of protocols enable proper diagnosis which provide scope for surgical planning. The diagnostic indications of surgical need are:
The therapeutic indications of surgical need are:
Vocal cord fat injection,
Ablation or excisional biopsy of pharyngeal glottic lesion,
What happens during a microlaryngeal surgery?
Microlaryngeal surgery involves the use of the two most essential tools in laryngeal surgery: the operative microscope, and microlaryngeal dissection instruments, which include the use of a laryngoscope. It is a thin lighted tube with a camera attached at the end to allow a surgeon to visualise the area with great precision. It is performed on patients under general anaesthesia, administered and monitored closely by an anaesthesologist working in close collaboration with a surgeon to avoid the danger of gagging or breathing problems.
The laryngoscope is inserted into the throat via the nose to locate the lesion. The abnormal growth is removed using tiny surgical tools that have been threaded through the laryngoscope into the affected area. This procedure permits greater exercise on the accuracy of surgery, focusing only on the affected area, thus, the surrounding area remains unharmed.
What happens after microlaryngeal surgery?
CARE Hospitals offer postoperative end-to-end care for patients undergoing microlaryngeal surgery to ensure faster recovery and improvement of health. The patient may be monitored closely for taking care of the needs arising after the surgery. Patients may experience some level of discomfort and may be administered some over-the-counter pain relieving medications. If required, postoperative voice therapy may also be recommended.
What are the associated risks?
Although this procedure is extremely safe, complications arising from micro laryngeal surgery are rare but can include a few postoperative side effects including temporary numbness, tingling of the tongue, and damage to the teeth. There may also be a risk of developing breathing problems, especially in patients having pre-existing heart or lung problems. There is also a risk of developing an allergic reaction to general anaesthesia or the medications used. The most problematic and challenging complication is the vocal cord scar.
