    ABSTRACT: The objective of this study was to evaluate the efficacy of a new surgical procedure for adductor spasmodic dysphonia (AddSD). This surgery involves the bilateral selective division of the adductor branches of the recurrent laryngeal nerves with immediate reinnervation of the distal nerve trunks with branches of the ansa cervicalis (selective denervation-reinnervation). Our first six patients to undergo this procedure were enrolled in the study. All patients suffered from AddSD and had previously received botulinum toxin A (Botox, Allergen, Markham, ON) therapy. Patients were recorded preoperatively and all underwent the same surgical procedure performed by the same lead surgeon. All patients were surveyed postoperatively and then re-recorded. Expert and untrained judges undertook perceptual evaluation of voice quality. Voice samples were also objectively evaluated for aphonic voice breaks. No major surgical complications were noted. Patient satisfaction was excellent, and five of the six patients no longer require botulinum toxin therapy. In five of the six patients, the majority of untrained and expert listeners perceived the postoperative voice to be superior. Objectively, the rate of aphonic voice breaks was also reduced in five of the six patients.

    ABSTRACT: Multiple etiological factors including gastroesophageal reflux, hyperfunctional voice use, and endotracheal intubation have been implicated in the development of posterior laryngeal ulcers and granulomas. The optimal approach to treatment of these lesions remains controversial. The mainstay of treatment at Vancouver General Hospital has been aggressive medical management of gastroesophageal reflux, with complimentary voice therapy offered to patients suspected of having significant hyperfunctional phonation. The authors reserve Botulinum toxin injection or surgical excision for patients who fail initial therapy. They conducted a retrospective analysis of their voice clinic records from 1985-1997 to examine the efficacy of this approach. They identified 76 patients with the diagnosis of contact ulcer or granuloma. Fifty-two patients had follow-up data available for review. Ninety-four percent of patients were treated nonsurgically: 35 patients were treated solely by dietary and medical therapy to control gastroesophageal reflux, 10 patients were treated by a combination of medical gastroesophageal reflux control and voice therapy, 3 patients had Botox injections, 2 patients had surgical excision of granuloma, 1 patient had a Kenalog injection, and 1 patient underwent laparoscopic fundoplication. Overall, 77% of patients had complete resolution, whereas 11% had partial resolution and another 11% had no significant improvement. The data supports control of gastroesophageal reflux as a central component in treatment of posterior laryngeal ulcers and granulomas.

    ABSTRACT: Muscular tension dysphonia, episodic laryngospasm, globus, and cough may be considered to be hyperfunctional laryngeal symptoms. Suggested etiological factors for these symptoms include gastroesophageal reflux, psychological problems, and/or dystonia. We propose a unifying hypothesis that involves neural plastic change to brainstem laryngeal control networks through which each of the above etiologies, plus central nervous system viral illness, can play a role. We suggest that controlling neurons are held in a "spasm-ready" state and that symptoms may be triggered by various stimuli. Inclusion criteria for the irritable larynx syndrome are episodic laryngospasm and/or dysphonia with or without globus or chronic cough; visible or palpable evidence of tension or tenderness in laryngeal muscles; and a definite symptom-triggering stimulus. thirty-nine patients with irritable larynx syndrome were studied. Gastroesophageal reflux was felt or proven to play a major role in a large number of the group (>90%), and about one third were deemed to have psychological causative factors. Viral illness seemed quite prevalent, with one third of patients able to relate the onset of symptoms to a viral illness that we feel might lead to central nervous system changes. Our proposed hypothesis includes a mechanism whereby acquired plastic change to central brainstem nuclei may lead to this form of hyperkinetic laryngeal dysfunction. It gives structure and reason to an array of therapy measures and suggests direction for basic research.
