Swallowing function outcomes following nonsurgical therapy for advanced-stage laryngeal carcinoma.

The purposes of this study were to (1) evaluate swallowing function using both subjective and objective measures in patients treated nonsurgically for stages III and IV laryngeal squamous cell carcinoma, (2) assess the effect of time from treatment completion on swallowing function, and (3) assess sequelae associated with modality of treatment. To achieve these objectives, a retrospective study of 14 patients was conducted. Fiberoptic endoscopic evaluation of swallowing (FEES) was performed and evaluated by three independent judges for seven functional criteria: standing secretions, valleculae spillage, valleculae residue, postcricoid residue, laryngeal penetration, aspiration, and cough. Patient interviews were performed to establish patient perception of swallowing and his/her current posttreatment diet. Results revealed that each patient exhibited swallowing abnormalities in at least one of the seven objective functional categories studied. Ten patients suffered from variable degrees of dysphagia, ranging from mild to severe, on all measures. No significant differences were noted between those patients with less than or greater than 12 months posttreatment. Common treatment sequelae included PEG tube placement for nutritional supplementation, tracheostomy placement for airway security and/or pulmonary toilet, repeated episodes of aspiration pneumonia requiring hospital admission, and radiation-induced oropharyngeal stricture. Further studies using subjective and objective swallowing function measures for patients treated with alternative chemoradiation regimens versus surgery (with or without adjuvant therapies) for advanced stage laryngeal cancer are needed.

Velopharyngeal dysfunction: speech characteristics, variable etiologies, evaluation techniques, and differential treatments.

This tutorial addresses the complex pathophysiology; various structural and neurologic causes; methods of clinical appraisal; and alternative behavioral prosthetic, and medicosurgical treatments of velopharyngeal dysfunction. To balance the primary focus of this review on hypernasal resonance and articulation disorders, discussions concerning hyponasal speech characteristics and underlying etiologies are also rendered.

Voice and deglutition functions after the supracricoid and total laryngectomy procedures for advanced stage laryngeal carcinoma.

OBJECTIVES: This investigation compared speech and deglutition functions after alternative surgical treatments for advanced stage laryngeal carcinoma: the supracricoid laryngectomy (SCL) versus the total laryngectomy (TL). Study design and setting Cohort investigation at Wayne State University School of Medicine. METHODS: Quantitative studies of laryngeal biomechanics, acoustic and speech aerodynamic features, and deglutition skills of these individuals were coupled to listener and patient self-impressions of speech and voice characteristics for group comparative analyses. RESULTS: Results revealed that patients from each subgroup performed comparably relative to speech intelligibility and voice quality disturbances. Videostroboscopy of the neoglottal mechanisms in these two populations helped to explain these outcomes. Acoustic and speech aerodynamic testing demonstrated variably abnormal features in both surgical subgroups. Whereas the SCL patients eventually achieved full oral diets, they required many sessions of swallowing therapy to obtain this objective and eliminate tube feeding supplementation. The TL patients did not evidence protracted swallowing difficulties or the need for specific exercises in order to remove their feeding tubes postoperatively. References to organ preservation strategies in lieu of surgical management are included for completeness purposes. CONCLUSIONS: The SCL and TL surgical procedures for advanced stage laryngeal carcinoma resulted in equivalent speech and swallowing functional outcomes.

Functional outcomes following nonsurgical treatment for advanced-stage laryngeal carcinoma.

OBJECTIVES: Objectives were 1) to provide comprehensive evaluations of functional outcomes using perceptual and objective measures of patients treated nonsurgically for stages III and IV laryngeal squamous cell carcinoma and 2) to propose a standard battery of tests that can be used for appraising functional outcomes in this patient population. STUDY DESIGN: Retrospective study of 14 patients. METHODS: Perceptual measures of voice were obtained using blinded expert listener impression ratings and a validated quality of life questionnaire (Voice Handicap Index). Objective data included acoustic, speech aerodynamic, and videostroboscopic evaluations. Patients were also assessed relative to stability of the airway, secretion control, and ability to tolerate oral diet without aspiration symptoms. RESULTS: Patients demonstrated functional but abnormal voice, speech, and swallowing abilities after treatment. More specifically, patients were judged to have moderately deviant biomechanical findings on videostroboscopy that did not improve with longer time intervals after treatment. These findings helped to explain the moderately abnormal acoustic and aerodynamic measurements revealing high values for jitter, shimmer, noise, airflow, glottal resistance, and subglottal pressures and substantially lower than normal maximum phonation times. Expert listeners were in agreement with the objective findings. However, patients rated themselves as only mildly impaired with regard to the emotional, physical, and functional handicapping effects of treatment, difficulties that were judged to improve with longer time intervals after treatment. Swallowing function showed a trend toward improvement for patients with time intervals of more than 12 months since completion of therapy. CONCLUSIONS: Patients demonstrated variable degrees of laryngeal dysfunction as evidenced by perceptual and objective measures. Patients rated themselves to be only mildly handicapped with regard to voice quality. A methodology and battery of tests are proposed to help standardize outcome data collection for this patient population.

Laryngeal anesthetization for the treatment of acquired disfluency: a case study.

UNLABELLED: The subject of this case study is an adult who became severely disfluent after a motor vehicle accident in which he did not suffer significant injuries. His disfluency persisted for 4 months notwithstanding a short trial of speech therapy. Hyperfunctional phonation subsystem disturbances were identified on follow-up evaluations. Laryngeal anesthetization was achieved via a transcutaneous lidocaine injection. The patient improved dramatically within 15 min of the procedure. More than 18 months later, he has retained normal speech fluency without any additional post-injection intervention. Theoretical discussions are rendered to help interpret this treatment outcome. EDUCATIONAL OBJECTIVES: The reader will be able to describe (1) the laryngeal movements and adjustments commonly associated with stuttered speech; (2) the speech dysfunctions a patient evidenced following a motor vehicle accident; and (3) the author's treatment rationale for resolving the patient's speech disorder.
