A voice restoration device are the devices which are used to produce the voice or develop the speech with the help of voice restoration therapy such as esophageal speech and stoma occulasion with thumb. Mostly, the voice restoration devices are used post laryngectomy, where the entire voice box known as larynx is removed permanently, separating the windpipe & food pipe. The most significant used device for voice restoration are trachea-esophageal valves which are implanted and are made up of silicone. The next preferred and only device used for voice restoration is electrolarynx. Elecrolarynx, also referred as throat back is a medical device about a size of electric razor, operated through a battery works by inducing the vibration of oral or pharyngeal mucosa, which in due course of action shapes the supplied vibration noise into understandable speech.
The large number of larynx cancer cases is driving the global voice restoration devices market. For instance, the global incidence of larynx cancer is around 136,000 new cases annually, with a 7:1 male predominance. There is a higher incidence of larynx cancer in western Asia with 6% of all cancers diagnosed in males are of larynx.
The global voice restoration devices market is segmented based on device type, which includes artificial larnyx (Electrolarynx), and tracheoesophageal voice prosthesis. Tracheoesophageal voice prosthesis is further classified into blom-singer valve, provox valve, and groningen valve. By end-user the global voice restoration market is segmented into multi-specialty hospitals, ENT hospitals, and ambulatory surgical centers.
Artificial larnyx (Electrolarynx) is the leading device type in the market, holding major share in 2017. The segment is exhibiting a significant growth owing to good alternatives to postlaryngectomy rehabilitation, and longer life cycles compared other voice restoration devices such as tracheoesophageal voice prosthesis. A significant advantage of the artificial larynx is that its use is often easily and rapidly learned, while major disadvantages include unnatural voice quality and the need to use a hand to speak.
The tracheoesophageal puncture is surgically inserted, either at the time of laryngectomy or as a delayed procedure, and a soft silicone, stenting catheter is advanced through and down the esophagus. After a week interval of healing, the catheter is removed and the tracheoesophageal tract is measured for length and fitted with a voice prosthesis. The most prominent advantage of tracheoesophageal voice is rapid recovery of fluent high-quality voice and speech. However, as with essentially all voice restoration techniques
The global voice restoration devices market was valued at US$ 210 billion in 2017 and is expected to witness a CAGR of 5.2% over the forecast period (2019–2025).
Growing incidences of laryngeal cancer:
The prevalence of throat cancer is increasing around the world. According to the National Cancer Institute (NCI), around 100,000 people in the US has laryngeal cancer in 2014. According to The American Cancer Society, 2017, around 13,150 new cases are added to the existing laryngeal cancer patients, out of 3,710 people are estimated to die from laryngeal cancer. With the rising cases of human papillomavirus (HPV) infection and the high consumption of tobacco and alcohol, the risk of laryngeal cancer is increasing which would further drive the demand for voice restoration devices market.
The U.S. is the major revenue generating region within voice restoration market owing to numerous cases of laryngeal and hypopharyngeal cancers and adoption of voice restoration devices in the region. The American Cancer Society estimated in 2015, there were 3763 death cases of larynx cancer in U.S. In 2016, larynx cancer mortality per incidence ratio in England is 45% in female and 36% in male. In 2017, the Canadian female mortality rate among larynx cancer was 40% and 19% mortality rate in man (per 100,000) population.
High cost of devices:
The high cost of devices and procedures might hamper the market potential. Various types of voice prosthesis and devices are available in the market. Many small-and medium-sized clinics cannot order and prepay for a minimum stock of different brands and sizes of devices due to lack of budget. The price of pneumatic artificial larynx devices ranges from approximately USD75 to USD150, while neck-type electrolarynx devices price varies from USD150 to USD800.
Few of the commercially available intraoral electronic larynx are the Cooper-Rand (Luminaud Inc, Mentor, Ohio), which costs approximately USD375, and the interdental Ultra Voice (Health Concepts, Inc, Malvern, Pennsylvania), with an estimated cost of USD2,000.
The acquisition is the dominant stagey adopted by the market players to enhance their product portfolio in the voice restoration market. For instance, Atos Medical acquired Griffin Laboratories to improve dedication to serving laryngectomee community. The acquisition was a part of backward integration by Atos, which was a long term customer of Griffin Laboratories.
Major players operating in the diagnostic devices market include Griffin Laboratories, Atos Medical, Inhealth Technologies, Nu-Vois, Ultravoice, and Luminaud Inc.
