Vocalization-associated respiration patterns: thermography-based monitoring and detection of preparation for calling.

Vocal emission requires coordination with the respiratory system. Monitoring the increase in laryngeal pressure, which is needed for vocal production, allows detection of transitions from quiet respiration to vocalization-supporting respiration. Characterization of these transitions could be used to identify preparation for vocal emission and to examine the probability of it manifesting into an actual vocal production event.

The carbon dioxide (CO2) laser is routinely used in glottic microsurgery for the treatment of benign and malignant disease, despite significant collateral thermal damage secondary to photothermal vaporization without thermal confinement. Subsequent tissue response to thermal injury involves excess collagen deposition resulting in scarring and functional impairment. To minimize collateral thermal injury, short-pulse laser systems such as the microsecond pulsed erbium:yttrium-aluminium-garnet (Er:YAG) laser and picosecond infrared laser (PIRL) have been developed.

Despite causing significant thermocoagulative insult, use of the carbon dioxide (CO2) laser is considered gold standard in surgery for early stage larynx carcinoma. Limited attention has been paid to the use of the erbium:yttrium-aluminium-garnet (Er:YAG) laser in laryngeal surgery as a means to reduce thermal tissue injury. The objective of this study is to compare the extent of thermal injury and precision of vocal fold incisions made using microsecond Er:YAG and superpulsed CO2 lasers.

Vestn Otorinolaringol
October 2001
Complex assessment of changes in laryngoscopic picture, direct laryngoscopy under anesthesia, tomography, thermography of the larynx and electrodiagnosis allows prognosis of recovery of motility of one of the vocal cords. The reflex spasm was relieved with corporal reflex therapy and novocain blockade of Zakharyin-Ged zones for the larynx. Out of 26 patients 11 recovered motility of the vocal cord due to the novocain blockades, 4--due to the corporal reflex therapy and 4 patients--spontaneously.
