Laryngeal and phonatory status after burn/inhalation injury: a long term follow-up study.
Although persistent hoarseness has been recognized in patients who have sustained burn and/or smoke inhalation injuries, there is little documentation to support this observation. Furthermore, there is no quantification of either the pervasiveness of the problem or the severity of the dysphonia resulting. It was the intent of this study to examine the laryngeal condition and voice production of a group of patients who were long-term survivors of burns and inhalation injuries. Only 10 patients (8 male and 2 female) of a larger cohort were willing to return for this examination. They were ambulatory and did not require respiratory assistance, and it had been 16 to 25 years since their initial traumas. Videostrobolaryngoscopic examinations were performed and analyzed, measures of various acoustic and aerodynamic parameters were made, and severity of dysphonia was judged. Seven of the 10 subjects were rated by experienced listeners as having some degree of dysphonia. All subjects had some abnormality of the laryngeal mucosa. Stroboscopic examination was found to be helpful in identifying laryngeal abnormalities in at least half of the subjects. Early attention to these problems, many of which are treatable surgically or behaviorally or both could lead to an improved voice for the patient and for this reason an improved quality of life.
