The certainty of a clinical diagnosis of rhinosinusitis requiring treatment is enhanced in patients with high symptom severity scores for fatigue, sleep disturbance, nasal discharge, nasal blockage, or decreased sense of smell. Isolated headache and facial pain or pressure are less reliable predictors of CT scan findings supporting the diagnosis rhinosinusitis.

Most patients with bilateral vocal cord paralysis have a fairly satisfactory voice, but their airway is usually compromised. The management of such patients presents a challenge to the otolaryngologist-head and neck surgeon. Numerous surgical procedures have been developed in an attempt to improve the patients's airway insufficiency without leaving him with a breathy, weak voice. Arytenoidectomy is currently the most reliable method of treating patients with bilateral vocal cord paralysis. Although both endoscopic and external approaches have been described for performing an arytenoidectomy, the endoscopic technique is more desirable since it requires no incision and theoretically allows for the immediate assessment of airway size. The addition of the CO2 laser to the surgical armamentarium offers certain refinements to the technique of endoscopic arytenoidectomy. Eleven patients with bilateral vocal cord paralysis of the larynx have been treated by endoscopic laser arytenoidectomy by the authors utilizing a technique developed by the two senior authors and subsequently taught to over 200 participants of the CO2 laser workshops sponsored by the Department of Otolaryngology-Head and Neck Surgery at Northwestern University Medical School; 10 of the 11 patients have been successfully decannulated. The technique and problems of this operation will be discussed.

In an attempt to establish a standardized rating system for CT of the paranasal sinuses, the Committee on Rhinology and Paranasal Sinus Disease of the American Academy of Otolaryngology-Head and Neck Surgery instituted a protocol for the review of sinus CT scans at six international sites. Fifty identical scans were rated by four otolaryngologists at each site according to five established sinus CT staging systems. Twenty of 24 reviewers repeated the rating session at least 1 week later to determine intrarater variability. The number of CT scans that could not be classified by a particular rating system ranged from 1.3% to 5.5%. The range of intrarater agreement (kappa = 0.39 to 0.74) exceeded that of interrater agreement (kappa = 0.18 to 0.49). A skewed distribution of CT scans resulted in a system with high rater agreement but poor ability to differentiate among disease states. The use of a numeric rating system to assign a score to each scan produced a comprehensive and disease-sensitive system, but one with low rater agreement. A precise definition of mucosal thickening in terms of millimeters appeared to enhance the raters' ability to assign stage and improve a system's comprehensiveness and reproducibility. On the basis of these findings, recommendations are made for the use of CT rating systems to study clinical outcomes in patients with chronic sinusitis.
