The Problem

Previous papers^1-3have reported on the feasibility of restoring the voice in patients suffering from paralytic dysphonia through injecting innocuous substances into the paralyzed vocal cord by means of the technique originally developed by Brünings.¹²Interpretation, diagnosis, and functional evaluation of laryngeal paralysis have been discussed in order to define which conditions are suitable for this procedure.^4-11 In the meantime, other authors have confirmed our experiences and suggested that further studies should be undertaken.^14-16,18The principle of restoring the voice through narrowing a deficient glottis has been corroborated also by J. G. Waltner,²⁰who implanted a cartilaginous graft lateral to the cicatricial cord with good functional results. It seems to be the consensus of these opinions that intracordal injection is a suitable method for vocal rehabilitation in various conditions when the vocal disability is due to insufficient closure of the vocal cords during1e:T504,Videofluoroscopy has long been viewed as the "gold standard" of swallowing examination for the comprehensive information it provides. However, it is not very efficient and accessible in some practical situations. In this study, we tried to use a modified technique of fiberoptic endoscopic examination of swallowing (FEES) in evaluating dysphagic patients. For each examination, a spoonful of pudding and dyed water were fed in sequence three times. The pharyngeal swallowing events were observed with fiberscope panoramically and videotaped. Twenty-eight chronic dysphagic patients underwent both videofluoroscopy and FEES in 2 weeks. Comparison of the results revealed that disagreements in premature oral leakage to the pharynx, pharyngeal stasis, laryngeal penetration, aspiration, effective cough reflex, and velopharyngeal incompetence were 39.3%, 10.7%, 14.3%, 14.3%, 39.3%, and 32.1%, respectively. FEES was found to be more sensitive in detecting these risky features of swallowing, except with respect to premature leakage. Possible causes of the discrepant results are discussed, and the limitation of videofluoroscopy in practical usage is discussed. FEES is conclusively a safer, more efficient, and sensitive method than videofluoroscopy in evaluating swallowing safety.1f:T43f,Since 1987, the authors have used a new technique for the augmentation and medialization of the paralyzed vocal cord. Eleven patients with paralyzed vocal cords and one patient with a surgical defect of the vocal cord have been treated with intracordal injections of autogenous fat harvested by suction from the abdominal wall. Treatment efficacy was evaluated by both subjective and objective (videostroboscopic) analyses. Patient follow-up has ranged from 5 to 42 months. All patients showed significant improvement in voice characteristics. Marked reduction in air flow and increased vocal intensity were observed. Correction of glottic insufficiency has been lasting, indicating that the implanted fat cells are viable. At this time, there has been no evidence of loss of vocal cord substance. The natural qualities of autogenous fat appear to make it an excellent alternative to Teflon or collagen. The fat is readily available, and easily harvested and injected. A larger patient population and longer follow-up periods will help determine if these initial findings are consistent.20:T57d,
