1/6. Da Vinci robot-assisted excision of a vallecular cyst: a case report.

    The da Vinci Surgical System is a new and exciting entrant into the field of robotic technology. This system is undergoing considerable research and is being practically applied in general surgery, cardiothoracic surgery, urology, and gynecology. We have previously described our experience with the da Vinci system in the laboratory setting, and we have reviewed its potential applications in otolaryngology. Here we present a case report of the first da Vinci-assisted excision of a vallecular cyst in a human. Although we initially encountered some difficulties in the setup, we were able to perform the procedure with moderate ease and without complication. The potential of the da Vinci system in otolaryngology is promising. Further research is needed to explore all of its possible uses in our field.

2/6. Dysphagia as a risk factor for sudden unexplained death in infancy.

    The TRIAD of encephalopathy, subdural haemorrhages, and retinal haemorrhages is commonly considered diagnostic of shaken baby syndrome, but the original paper describes a statistically linked QUADRAD of features, the fourth of which is a previous history of feeding difficulties (dysphagia). Recent reviews of giving pacifiers (dummies) to infants during sleeping periods have found a significant reduction in the incidence of sudden infant death Syndrome. Stimulation of swallowing is a possible connection with dysphagia, which is examined here, illustrated by a well documented case. Although amniotic fluid passes freely through the larynx of fetal mammals during fetal breathing, application of pure water to the laryngeal epithelium in infants causes choking and laryngeal closure. "water sensors" in the surface respond to lack of chloride ions and adapt very slowly or not at all. Others have found in puppies that following application of pure water only 32% resume breathing in less than 30-40s. The rest needed at least one saline flush, and some required artificial ventilation in addition. These receptors also respond to high potassium concentrations and acid or alkaline solutions. Normally, airway closure during swallowing or vomiting prevents entry of feed or oesophageal reflux, but in some forms of dysphagia leakage can occur, causing paroxysmal coughing, reflex laryngeal closure, and so prolonged apnoea. Recently, it has been realised that the TRIAD injuries can also result from high intracranial vascular pressures transmitted from intra-thoracic pressure surges during paroxysmal coughing, choking, etc. Triggering of such pressure surges by dysphagic accidents provides a physiological link to injuries commonly considered diagnostic of shaken baby syndrome, completing the statistically identified QUADRAD of features. Further dysphagic research might reveal predictive factors, and preventative measures such as feeds of optimal pH.

3/6. Evaluation of swallowing disorders: the modified barium swallow.

    Swallowing is a complex process. The diagnosis and treatment of swallowing dysfunction are more objective due mostly to recent research. The performance of a barium swallow, modified to study the dynamics of swallowing and its value in the management of patients with swallowing dysfunction, is described. The conventional barium swallow assesses structure and function of the thoracic esophagus, including gastroesophageal reflux and its sequelae. The modified barium swallow is a dynamic technique designed to evaluate swallowing function and dysfunction as it relates to the oral and pharyngeal phases of swallowing.

4/6. Electroglottographic evaluation of the swallow.

    The feasibility of using the electroglottograph (EGG) to record and measure aspects of the swallow was tested in six nonimpaired, two parkinsonian, and two dysphagic subjects. Low-frequency changes in tissue impedance across the neck were recorded with an EGG during deglutition. On six nonimpaired subjects, EGG waveforms were consistently monophasic and appeared to be well timed with laryngeal height changes. The waveforms of the two dysphagic subjects differed markedly from those of the nonimpaired subjects, and their timing and shapes were consistent with videofluoroscopic descriptions of those of the dysphagic subjects. The two parkinsonian patients also showed aberrant waveform patterns. These observations suggest that use of the EGG has strong potential as a quantitative technique for swallowing evaluation, therapy, and research.

5/6. A swallow induction avoidance procedure to establish eating.

    Swallow induction has been used to shape swallowing behavior in dysphagic children and to accelerate swallowing in nondysphagic children with profound mental retardation who display primitive swallows. Swallow induction may be considered a type of prompt. This project coupled swallow induction with a modified delayed prompting paradigm to establish eating in a 3.5-year-old girl. Coupling these procedures produced prompt swallowing and established oral consumption. Follow-ups at 1, 2, 6 and 12 months demonstrated maintenance and further improvement of the newly acquired feeding skills. Implications for treatment and further research are discussed.

6/6. A pilot exploratory study of oral electrical stimulation on swallow function following stroke: an innovative technique.

    This pilot study investigated the effect of oral electrical stimulation on swallow function in stroke patients with chronic dysphagia. The purpose was to determine whether an innovative technique could make an improvement in swallow function that might be developed as a potential treatment for patients with persistent dysphagia. Four stroke patients with chronic dysphagia were recruited on the basis of videofluoroscopic findings of a delayed swallow reflex. A single case design was used. Oral electrical stimulation of swallowing was carried out using a palatal prosthesis starting at an output pulse of 0.5 mA, with a fixed duration of 200 microsec, repeated at 1-sec intervals. barium paste (1 x 5 ml) was introduced at the level of the patient's maximum tolerance of stimulation and any effect on swallow function was recorded by videofluoroscopy. The findings from the pilot study indicated that oral electrical stimulation resulted in an improvement in swallow function in 2 of the 4 patients. The stimulation was well tolerated in all cases with no serious adverse effects. These early results are promising, but further research is needed.
