Current trends in pediatric tracheotomy

A retrospective analysis was performed on 103 pediatric patients, less than 5 years of age, undergoing tracheotomy at New York Hospital between 1980 and 1990. Charts were reviewed with respect to primary diagnosis, indication for tracheotomy, duration of the tracheotomy, complication rate and mortality rate. Approximately 62% of the tracheotomies were performed in patients less than 12 months of age, with the most common indication being an acquired or congenital airway abnormality. The number of patients receiving tracheotomies for neurological disorders, however, increased more than threefold over the course of this review. Approximately one-third of the patients experienced immediate, early or delayed complications. There was a significant correlation between the complication rate and weight at the time of the tracheotomy as well as the degree of prematurity of the child. Over one half of the infants under 2000 g suffered complications. A mortality rate of 2.9% was noted in our study with mucous plugging of the tracheotomy being the most common etiology of death.

Effects of Scalpel, Electrocautery, and CO2 and KTP Lasers on Wound Healing in Rat Tongues

Objective: Evaluate wound healing of incisions created by the scalpel, electrocautery, CO2 laser, and potassium titanyl phosphate (KTP) laser in the upper aerodigestive tract in an animal model.

Surgical Management of Congenital Saccular Cysts of the Larynx

Congenital saccular cysts of the larynx are unusual lesions that commonly present with respiratory obstruction in infants and children. The saccular cyst may result from an atresia of the laryngeal saccule orifice or may represent the retention of mucus in the collecting ducts of submucosal glands located around the ventricle. Traditionally, the treatment of the lesions has been endoscopic unroofing or marsupialization. Frequently, this modality requires multiple procedures as well as concomitant tracheotomy. There also have been reports of acquired subglottic stenosis. We have found that removal of the recurrent saccular cyst can be achieved relatively safely and effectively via a lateral cervical approach to the thyrohyoid membrane. We review our experience with four patients with congenital saccular cysts and detail the evaluation and surgical management of these lesions.

Airway growth after cricotracheal resection in a rabbit model and clinical application to the treatment of subglottic stenosis in children.

Objective To evaluate the effects of a partial resection of the anterior cricoid arch on the growth of the laryngotracheal complex in an animal model and to study the lumen caliber and cross sectional surface area following resection as the animals are allowed to grow. Laryngeal, subglottic, and tracheal measurements in the infant and pediatric larynges in autopsy specimens are also investigated.

Congenital nasal pyriform aperture stenosis: non-surgical management and long-term analysis.

Congenital nasal pyriform aperture stenosis is a rare cause of airway obstruction in the newborn. Immediate recognition and therapy are essential for this potentially life-threatening condition. After initial management, which includes establishment of an oral airway, surgical repair of the stenotic bony inlet has been traditionally considered. We present a long-term follow-up of two patients with congenital pyriform aperture stenosis, who were managed expectantly. Pertinent embryology, clinical presentation, and general treatment strategies for these patients are also discussed.

Minimally invasive techniques in laryngotracheal reconstruction.

The treatment of laryngotracheal stenosis has evolved over the past several decades. Advances in technology, equipment and medication have increased our ability to treat some airway stenosis in a minimally invasive manner, and at times by an endoscopic method. With improved precision, our results with postoperative voice and swallowing should improve.

Computed Tomography and the Thyroglossal Duct Cyst

Thyroglossal duct cysts (TDC) classically present as midline neck masses in close relation to the hyoid bone; yet—not uncommonly—their locations may be varied from the midline and from the hyoid. By means of the diagnostic modality of computed tomography (CT), high-resolution images of several cases of alternate presentations and locations of the TDC are examined. Included are examples of TDC in the suprahyoid, transhyoid, infrahyoid, and lateral positions. The potential value of CT in the diagnosis of the unusual cyst will be demonstrated and discussed.

A pilot study of balloon dilation in an animal model resulting in cricoid cartilage fracture: Implications for the stenotic pediatric airway†‡

Endoscopic balloon dilation is increasingly popular as primary therapy for infants with subglottic stenosis. We aim to determine the maximum balloon diameter and pressure where no fracture of the cricoid would occur, minimum balloon size and pressures where a gross fracture of the cricoid occurs, and location of these fractures. We tested these objectives by performing balloon dilation in laryngotracheal complexes of eight euthanized adult male New Zealand white rabbits, with airway characteristics similar to a 3‐ to 9‐month‐old infant.

Age-related tonsillar regrowth in children undergoing powered intracapsular tonsillectomy

OBJECTIVES To review our experience with intracapsular tonsillectomy using powered instrumentation (PIT) in the management of tonsillar hypertrophy. DESIGN Retrospective database review of pediatric patients undergoing PIT. METHODS The medical records of 636 patients under 11 years of age who underwent PIT performed by the senior author (RFW), predominantly for obstructive sleep disturbance, were reviewed. Data were subsequently analyzed from 559 of these patients for clinical evidence of tonsillar regrowth, post-operative tonsillar hemorrhage, and post-operative dehydration due to pain. Specific information for possible correlation of age at the time of surgery and any increased rate of regrowth was primarily examined. RESULTS There were a total of 33 patients who had clinical evidence of regrowth. Children less than 5 years of age had 5 times the incidence of regrowth (p<0.001). Out of the group that exhibited regrowth, 5 patients exhibited evidence of recurrent upper airway obstruction and underwent a complete tonsillectomy. The age of this complete tonsillectomy group ranged from 1.1 to 2.7 years. Out of all patients undergoing PIT, there was 1 incident of delayed post-operative dehydration due to emesis but not due to pain. There were 2 incidents of delayed post-operative tonsillar bleeds. All three complications were self-limited and did not require re-hospitalization. CONCLUSIONS PIT is a safe procedure with a small risk of tonsillar regrowth being age related. The incidence of postoperative complications following PIT is relatively low (0.54%).

Endoscopically placed nitinol stents for pediatric tracheal obstruction

OBJECTIVE To provide preliminary clinical data regarding endoscopically placed nitinol stents for children with tracheal obstruction as a temporizing measure to allow for trach tube decannulation while awaiting growth to allow for tracheal resection. METHODS This case series describes the experiences of two children (ages 5 and 15) who were dependent upon tracheotomy because of acquired tracheal obstruction. Both patients had combined tracheomalacia and tracheal stenosis. After failing tracheoplasty with rib graft augmentation both patients suffered from extensive tracheal disease, which was too long to allow for immediate tracheal resection. INTERVENTION Endoscopic placement of nitinol stents in the obstructed tracheal segment using fluoroscopic guidance. All tracheotomy tubes were removed immediately after successful stent deployment with the patient still under general anesthesia. RESULTS Four stents were placed in total. The first patients initial stent was too narrow and was, therefore, removed and replaced at a later date with a larger diameter stent. The second patient experienced distal migration of his initial stent requiring stent removal and replacement at a later date. Both patients remain successfully decannulated (follow-up, 25 and 26 months) and are currently living more normal lives as they grow and await tracheal resection. CONCLUSION Preliminary use of nitinol stents for pediatric tracheal obstruction has enabled successful decannulation in two children with complicated airways. Our results with this series of patients suggest that nitinol stents can be safely used in children as a temporizing measure until tracheal resection can be safely performed. With this approach children can live free from the hassles of trach care, social isolation and peer ridicule. Limited pediatric experience exists in the literature about nitinol stents. Thus, our experience with stent selection and placement will help others avoid problems encountered in this initial series.
