Tracheal Stoma

To investigate the relationship between the electrical activity of the genioglossus (GG-EMG) and associated tongue movement, seven laryngectomized subjects breathing through a tracheal stoma (without pressure or flow change in the upper airway) were studied in the supine position. Tongue movement, with the use of lateral fluoroscopy, and GG-EMG expressed as a percentage of maximum voluntary genioglossal activation were monitored simultaneously during 1) spontaneous inspiration (SI), 2) resistive loaded inspiration (LI), and 3) rapid inspiration (RI). Tongue position during each maneuver was compared with its position during spontaneous expiration. Peak GG-EMG during the three maneuvers was significantly different from each other (SI: 5.4 +/- 1.6, LI: 11.9 +/- 1.8, and RI: 51.6 +/- 9.4 (SE) %, respectively). Associated forward movement of the posterior aspect of the tongue was minimum during SI; however, significant movement was observed during LI, and this was increased during RI. Significant covariance existed between peak GG-EMG and this movement. Genioglossal coactivation with inspiration enlarges the glossopharyngeal airway, particularly in its caudal part. In subjects with intact upper airways, this activation may protect or enhance upper airway patency in an effort-dependent manner.

The physiological mechanisms mediating the detection of mechanical loads are unknown. This is, in part, due to the lack of an animal model of load detection that could be used to investigate specific sensory systems. We used American Foxhounds with tracheal stomata to behaviorally condition the detection of inspiratory occlusion and graded resistive loads. The resistive loads were presented with a loading manifold connected to the inspiratory port of a non-rebreathing valve. The dogs signaled detection of the load by lifting their front paw off a lever. Inspiratory occlusion was used as the initial training stimulus, and the dogs could reliably respond within the first or second inspiratory effort to 100% of the occlusion presentations after 13 trials. Graded resistances that spanned the 50% detection threshold were then presented. The detection threshold resistances (delta R50) were 0.96 and 1.70 cmH2O.l-1.s. Ratios of delta R50 to background resistance were 0.15 and 0.30. The near-threshold resistive loads did not significantly change expired PCO2 or breathing patterns. These results demonstrate that dogs can be conditioned to reliably and specifically signal the detection of graded inspiratory mechanical loads. Inspiration through the tracheal stoma excludes afferents in the upper extrathoracic trachea, larynx, pharynx, nasal passages, and mouth from mediating load detection in these dogs. It is unknown which remaining afferents (vagal or respiratory muscle) are responsible for load detection.

Tracheostomy Tubes

Tracheostomy tubes are chosen primarily based on their internal diameter; however, the length of the tube may also be important. We performed a prospective clinical audit of 30 critically ill patients following tracheostomy to identify the type of tracheostomy tube inserted, the incidence of malpositioning and the factors associated with the need to change the tracheostomy tube subsequently. Anthropometric neck measurements, distance between the skin and tracheal rings and the position of the tracheostomy cuff relative to the tracheal stoma were recorded and analysed. Malpositioning of the tracheostomy tube was noted in 20%, with a high riding cuff being the most common cause of malpositioning, resulting in an audible leak and a need to change the tracheostomy tube subsequently. A high riding cuff was more common when a small tracheostomy tube (e.g. Portex (Smiths Medical Australasia, Macquarie Park, NSW) ≤8.0 mm internal diameter with length <7.5 cm) was used, with risk further increased when the patient’s skin to trachea depth was greater than 0.8 cm. Identifying a high riding cuff relative to the tracheal stoma confirmed by a translaryngeal bronchoscopy strongly predicted the risk of air leak and the need to change the tracheostomy tube subsequently. Our study suggests that when a small (and short) tracheostomy tube is planned for use, intraoperative translaryngeal bronchoscopy is warranted to exclude malpositioning of the tracheostomy tube with a high riding cuff.

AbstractThis is a modified subtotal laryngectomy. On the tumour-free side of the larynx, some posterior structures, with their neurovascular supply are preserved. The endolaryngeal mucosa is tubed in continuity with the trachea below and projects into the pharynx above. Thus a myomucosal shunt is formed. Air is directed into it by finger occlusion of the tracheal stoma.The voice production is highly satisfactory. Aspiration is prevented by constriction of the thyroarytenoid muscle which provides a valved upper end of the tube.The possibility of leaving tumour in the laryngeal remnant is eliminated by careful selection of patients, and re-confirmation of tumour extent intra-operatively and a frozen section.Eleven such operations have been performed since October 1983 for squamous cell carcinoma, some previously irradiated. None of the patients had local recurrence. Only one had an aspiration problem which later resolved. All acquired a satisfactory voice
