Functional outcomes after supracricoid laryngectomy.

OBJECTIVES: Local control and 5-year survival rates are similar for patients undergoing total laryngectomy and supracricoid laryngectomy for the treatment of advanced-stage laryngeal carcinoma. However, comprehensive studies of functional outcomes after supracricoid laryngectomy are lacking. STUDY DESIGN: Cohort study. METHODS: This investigation provides objective voice laboratory data, skilled listener impressions of voice samples, swallowing evaluations, and patient self-perceptions of speech ability obtained from 10 supracricoid laryngectomees. RESULTS: Results demonstrated variable acoustic and speech aerodynamic disturbances, hoarse-breathy vocal quality, and speech dysfluency. Patients' self-perceptions of voice revealed severe dysphonia that induced certain emotional, physical, and functional setbacks. However, blinded judges rated these individuals as possessing intelligible speech and communication skills. All patients demonstrated premature spillage of the bolus and varying degrees of laryngeal penetration, aspiration, and retention during swallowing studies. However, each patient used a compensatory strategy to protect the airway. Voice and swallowing abilities appeared to depend on the mobility of the arytenoid cartilages, base of tongue action, and residual supraglottic tissue for the creation of a competent neoglottal sphincter complex that vibrated during phonation efforts and protected the airway during deglutition. CONCLUSIONS: Supracricoid laryngectomy avoids the potential complications, limitations, and emotional problems associated with a permanent tracheostoma. All patients demonstrated intelligible voice and effective swallowing function postoperatively, supporting supracricoid laryngectomy as a suitable alternative surgical approach to the total laryngectomy in select patients.

Craniocervical necrotizing fasciitis: an 11-year experience.

OBJECTIVE: We review our experience and present our approach to treating craniocervical necrotizing fasciitis (CCNF). STUDY DESIGN: All cases of CCNF treated at Wayne State University/Detroit Receiving Hospital from January 1989 to April 2000 were reviewed. Patients were analyzed for source and extent of infection, microbiology, co-morbidities, antimicrobial therapy, hospital days, surgical interventions, complications, and outcomes. RESULTS: A review of 250 charts identified 10 cases that met the study criteria. Five cases (50%) had spread of infection into the thorax, with only 1 (10%) fatality. An average of 24 hospital days (7 to 45), 14 ICU days (6 to 21), and 3 surgical procedures (1 to 6) per patient was required. CONCLUSION: Aggressive wound care, broad-spectrum antibiotics, and multiple surgical interventions resulted in a 90% (9/10) overall survival and 80% (4/5) survival for those with thoracic extension. SIGNIFICANCE: This is the largest single institution report of CCNF with thoracic extension identified to date.

Scintigraphic quantification of aspiration reduction with the Passy-Muir valve.

The Passy-Muir "speaking" tracheostomy valve has been noted to aid in swallowing, based on videofluoroscopy to assess aspiration. In this study scintigraphy was used to quantify the amount of material aspirated. Eleven patients were studied who currently had a tracheostomy in place and were either known to aspirate or were suspected of aspirating. Most were post-treatment head and neck cancer patients who were tumor free at the time of testing. Swallowing was evaluated using videofluoroscopy and scintigraphy. Videofluoroscopy was performed to assess anatomy and determine whether aspiration had occurred. Scintigraphic testing was then performed when the patient had the one-way valve on, and again with it off and tracheostomy open. Following a swallow, the amount (%) of aspirate with the valve in place was found to be significantly less than with the tracheostomy open. A one-way valve can be helpful in reducing aspiration in patients who are at risk for aspiration and who require that their tracheostomy be open.

Scintigraphic assessment of swallow efficiency postlaryngectomy.

There have been reports of a high incidence of hypopharyngeal stenosis in total laryngectomy patients when the surgery requires a partial pharyngectomy for pyriform sinus involvement. In this study, three groups were compared: total laryngectomy patients without partial pharyngectomy, total laryngectomy patients with partial pharyngectomy, and normal controls. All patients had received radiation therapy following surgery. All were maintaining oral nutrition, and none complained of dysphagia. Patients were tested between 1 and 7 months postradiation therapy, with a mean of 3 months. Measures of swallowing efficiency were based on scintigraphic data for a liquid swallow. Patients with partial pharyngectomy had abnormally long oropharyngeal transit times and low efficiency scores. For a subgroup of patients with partial pharyngectomy, swallowing data were available postsurgery and postradiation therapy. Postsurgery this patient group did not differ significantly from normal patients in swallowing efficiency, and swallowing efficiency deteriorated in postradiation therapy. This scintigraphic methodology is shown to be a sensitive method of assessing swallowing function in this patient population.

Swallowing of bolus types by postsurgical head and neck cancer patients.

BACKGROUND: Clinically, head and neck cancer patients with anterior resections have better postoperative outcomes than do patients with posterior resections. METHODS: Videofluoroscopy was used to study the swallowing characteristics in postsurgery head and neck cancer patients and normal controls. Most patients received post-operative radiotherapy and chemotherapy, and no cancer recurrence was noted at the time of study, 4-8 months posttreatment. Bolus types included: 3 mL and 10 mL liquid barium, barium paste, and barium-coated cookie. Temporal measurements and a count of the number of swallows required to ingest each material were made from the videotaped data. Statistical analysis using an unbalanced univariate repeated measures ANOVA was performed. RESULTS: The major differences were found between bolus types, with few differences noted between surgical groups (anterior vs posterior resections) and normal controls. Patients took longer to ingest viscous material, accomplishing this by multiple piecemeal and clearing swallows. Coordination of mastication and swallowing of the cookie was different between normal and patient groups. CONCLUSIONS: Patients who are able to swallow reasonably well postoperatively maintain normal coordination and timing of swallowing activity and do not vary these parameters to compensate for structural inadequacy. Instead, repeated swallows are used.

Clinical accuracy of capillary blood glucose monitoring in hospitalized patients with diabetes.

This study evaluated the clinical accuracy of capillary blood glucose monitoring (CBGM) performed by nursing personnel on hospitalized patients with diabetes. We compared the results of 80 serum glucose samples obtained in a blinded fashion within 5 minutes of routine capillary glucose measurements performed during the course of clinical care. The CBGM results obtained by a diabetes nurse specialist during endocrine testing procedures were correlated with the serum results. Correlation of CBGM to serum glucose ranged from .74 to .99 depending on the method used. Visual and manual interpretation yielded the lowest correlation and variable accuracy results, per error grid analysis, with 1 in 4 patients having errors of sufficient magnitude that could lead to inappropriate therapy. Monitoring with the AccuChek II blood glucose meter produced the highest correlation and most accurate clinical readings. Bedside blood glucose monitoring of inpatients has a wide range of reliability depending on the method used.
