The anterior cricoid split: the Children's Hospital of Philadelphia experience.

The anterior cricoid split procedure (ACS) is an alternative to tracheotomy in selected infants with subglottic stenosis. From February 1983 to October 1987, 26 children underwent ACS at the Children's Hospital of Philadelphia. All children had subglottic stenosis. Six children had previously undergone tracheotomy. A successful outcome, allowing extubation or decannulation, correlated only with decreased pre-operative intubation time and was achieved in 73% of these patients. A failed ACS had little adverse affect on the subsequent management of these children.

[Is there a consensus in the division of the vocal folds in thirds?].

INTRODUCTION: In clinical routine we have noticed a disagreement of ENT-specialists and phoniatricians in the division of the vocal folds in thirds. To show if there is consensus in this field by the german phoniatricians this study was done. MATERIAL AND METHODS: In two parts of a study, a pilot study and a follow up study, we sent twelve different images of the larynx to all german phoniatricians. In six of these images the physicians should set the marks of the ventral and dorsal limitation of the second third of the vocal folds. In six different images a mark should be related to the particular third of the vocal folds. The phoniatricians were asked to assess how certain they were in their valuation. They were asked either, how long they have been working as a physician and how long they have been specialized as a phoniatrician and as an ENT-surgeon. In the follow up study the phoniatricians were requested to first divide up the thirds in a way that the dorsal third corresponds to the cartilaginous part of the vocal folds (scheme 1) and second divide up the thirds in a way that all three thirds correspond to the ligamental part of the vocal folds. DISCUSSION AND FINDINGS: In the pilot study, when no instructions for the division of the thirds were given, the data differed much more than in the follow up study, when the physicians were told to use scheme 1 and scheme 2. That was because some phoniatricians divided up just the ligamental part and others the ligamental plus the cartilaginous part of the vocal folds in thirds. The more the physicians could overlook the membraneous part of the vocal folds the more certain they were in their assessment. CONCLUSION: The assessment of the division of the vocal folds in thirds is more homogeneous when the phoniatricians were requested to divide up the thirds in a way that the dorsal third corresponds to the cartilaginous part of the vocal folds (scheme 1). Therefore we suggest that this way of division should be used further on.

Composite hyoid-sternohyoid interposition graft revisited: UCLA experience 1974-1984.

The surgical correction of severe laryngotracheal stenosis remains a challenging problem. We report on a series of 20 patients treated with the composite hyoid-sternohyoid interposition graft (HSIG). They range in age from 1 to 66 years and all had severe subglottic stenosis refractory to dilatation and stenting procedures. The major cause of stenosis was prolonged endotracheal intubation (16/20); the majority of patients (13/20) had severe medical illness complicating their airway management. Postoperative results were judged on the basis of decannulation, voice strength, and quality as well as activity tolerance. Follow-up periods were over 24 months in all cases. Twelve patients were decannulated and three keep their tracheotomy tubes permanently plugged. All have socially acceptable voices and good activity tolerance. Seven patients who were aphonic had voice improvement. There were three complete failures; one secondary to infection, one due to severe scleroderma, and one because of graft displacement. Each patient underwent an average of four postoperative endoscopies for airway evaluation and removal of granulation tissue. CAT scanning was useful in diagnosing postoperative problems, especially graft displacement, which was impossible to diagnose by endoscopic examination. We conclude that the composite hyoid-sternohyoid interposition graft is a useful and reliable tool in the treatment of subglottic stenosis.

Prehospital cricothyrotomy: an investigation of indications, technique, complications, and patient outcome.

The records of all patients who presented to a Level 1 trauma center during a two-year period for whom a prehospital cricothyrotomy was attempted or ordered were reviewed. Twenty patients met the study criteria. The average age was 37 years (range, 11 to 65 years). Indications for prehospital cricothyrotomy were massive facial trauma (eight), failed oral intubation (seven), and suspected cervical-spine injury (one). Cricothyrotomy was attempted in 16 patients (80%), with the remaining four having the procedure ordered but not attempted. A successful airway was achieved in 14 patients (88%). Horizontal incisions were used in all cases and were anatomically correct in 15 of 16 attempts (94%). The overall immediate complication rate was 31%. Two patients (12%) sustained major complications (failure to obtain an airway). No hemorrhagic complications occurred, but 16 of the 20 were in cardiac arrest in the field. Long-term complications were not evaluated. All patients sustained major injuries (mean Injury Severity Score, 53.7), except one patient who suffered airway obstruction from food. Three patients (15%) survived; two of the three suffered permanent, severe brain dysfunction. These preliminary findings demonstrate that prehospital cricothyrotomy is being used chiefly in massively injured patients who are already beyond recovery. It is thus difficult to assess whether the procedure is either safe or effective. There is a need for further investigation to determine whether prehospital cricothyrotomy has any beneficial effect on outcome and, if so, in what setting.(ABSTRACT TRUNCATED AT 250 WORDS)

A personal experience with subtotal and conservation surgery as treatment for laryngeal cancer.

A personal technique for laryngeal cancer reconstructive surgery is presented and discussed. The functional and therapeutic purpose of this surgery is to broaden its indications and to improve functional results. In particular, our surgical technique involves removal of the soft internal part of the cricoid cartilage (mucosa, submucosa and perichondrium), which is otherwise conserved. Satisfactory functional results can be achieved by: modeling of two symmetrical pseudoarytenoids; an anterior epiglottiplasty or the use of a Hiranandani base-of-the-tongue flap to close the anterior gap (if present); muscular flap lateral-plasty avoiding a cricoidhyoidpexy.

Experimental studies for correction of superior laryngeal paralysis by fusion of the thyroid to cricoid cartilages.

Contraction of the cricothyroideus muscles (CTMs), innervated by the superior laryngeal nerves (SLNs), modulates the voice by tilting the thyroid cartilage anteriorly onto the top of the cricoid and tensing the vocal cords. Either unilateral or bilateral paralysis of the SLNs is disabling for individuals with above-average voice demands. Some patients never compensate for this paralysis; there is no surgical procedure recognized to correct it. This study tested the hypothesis that surgical fusion of the thyroid and cricoid cartilages anteriorly can correct the problems of SLN injury by duplicating the mechanical tilt of the thyroid onto the cricoid cartilage normally produced by the CTMs. The SLNs were cut in 12 dogs. In six the cricoid and thyroid cartilages were fused anteriorly. Vocal cord and airway function was assessed preoperatively, immediately postoperatively, and 6 to 10 weeks after surgery. Following surgery there was no airway compromise and there appeared to be a more satisfactory compensation for the SLN paralysis in the fused larynges as compared with the unfused controls as determined by cinelaryngoscopic analysis.

The anterior cricoid split. Clinical experience with extended indications.

A recommended approach to postextubation infant subglottic stenosis secondary to subglottic edema employs the recently described anterior cricoid split (ACS) procedure. This technique provides an expanded subglottic airway with minimal paratracheal dissection and does not require concomitant tracheotomy. We applied this procedure in managing extubation difficulty in pediatric as well as neonatal patients. Five of ten patients in our series did not fulfill the traditional criteria for ACS. Relief of stridor and avoidance of tracheotomy were accomplished in nine of ten patients. One patient in whom mechanical ventilation was reinstituted developed an interesting complication. In properly selected infants with subglottic airway compromise, the ACS appears to be an effective adjunct in facilitating extubation.

Laryngotracheal stenosis in spondyloepiphyseal dysplasia.

Laryngotracheal stenosis has not been reported previously as a manifestation of spondyloepiphyseal dysplasia. Two recent cases are reported detailing the upper airway pathology encountered. The clinical features of spondyloepiphyseal dysplasia are reviewed in an attempt to develop a treatment protocol for such patients with laryngotracheal stenosis. The ultrastructural abnormalities found in these patients' cartilages are emphasized. Caution is advised before attempting laryngotracheoplasty.
