Perioperative management of paediatric microstomia.

Paediatric microstomia may occur congenitally in the whistling face syndrome but is more often acquired after accidental thermal injuries such as biting an electrical extension cord or ingesting household lye. The surgical correction of microstomia includes separation and cosmetic reconstruction of the fused lips and postoperative oral splinting. Microstomia from lye ingestion may be associated not only with limited mouth opening but also with such severe intraoral scarring that common landmarks guiding either rigid or flexible fibreoptic laryngoscopy are obscured, rendering oral and nasotracheal intubation difficult or impossible. We report a case of paediatric microstomia after lye ingestion in which conventional direct laryngoscopy, flexible fibreoptic laryngoscopy, and multiple blind nasal approaches to tracheal intubation were unsuccessful. However, tracheostomy was avoided and successful tracheal intubation was accomplished using a new rigid tubular pharyngolaryngoscope.

Isolated uvulitis secondary to marijuana use.

Isolated uvulitis is a rarely reported disease. Known etiologies include bacterial infection and trauma following the use of instrumentation in the airway. Three cases of isolated uvulitis secondary to heavy marijuana smoke inhalation are reported. Specific recommendations regarding diagnosis and treatment of this disorder are made.

A technique for intubation of the difficult airway.

Intubation of a patient with an obstructive friable tumor mass in the hypopharynx can be difficult. A technique for solving our most difficult cases evolved after all current methods had been tried. This technique combines the use of a tubular laryngoscope and a hollow wand (or guide), through which O2 can be delivered into the trachea as the endotracheal tube is advanced past the obstructing lesion. Existing techniques are also discussed.

Endotracheal tube ignition during laser surgery of the larynx.

The ignition of an endotracheal tube was caused by laser penetration of an unprotected portion of the tube during resection of laryngeal papillomas. We discuss the factors that contributed to the ignition, the hazards that were encountered, and the methods of prevention that were used.

Nasal masses in infants and children.

Nasal or perinasal masses in children may be classified as congenital or developmental masses, inflammatory lesions, or benign or malignant neoplasms. Because of a possible connection with the central nervous system, nasal masses may be difficult to manage. A premature biopsy, or even a noninvasive palpation, may precipitate intracranial infection, meningitis, or severe bleeding. The indolent nature and benign appearance of these lesions shold not lead to deferral of complete evaluation and appropriate treatment.

Laryngotracheal separation.

The popularity of the motorcycle, specifically trail bike riding, in the past several years has produced an increasing incidence of severe "clothesline" injuries to the larynx and trachea. Even at moderately high speed the impact of a horizontal cable with the neck of the rider causes a sudden hyperextension of the neck, and an avulsion of the larynx from the trachea, separating at the relatively rigid fibrous connective tissue between the cricoid cartilage and the first tracheal ring. Interruption of the strap muscles, the recurrent laryngeal nerves, laceration of the esophagus, and compression fracture of the cervical vertebral bodies can occur. The unseated rider requires immediate assistance, airway obstruction being his greatest problem. In the early minutes after the accident he must be transported to an emergency facility where tracheostomy and resuscitation can be provided. Mediastinal infection, tracheoesophageal fistula, subglottic stenosis, and intermittent depression many follow the initial repair. Rehabilitative measures include permanent tracheostomy, the use of neuromuscular pedicle graft, hyoid bone graft, intracordal injection of teflon paste, and carbon dioxide laser excision of webs and cicatricial tissue.

Laryngeal problems in space travel.

A start has been made in enumerating possible problems of the larynx, in short or moderately long space voyages, based on our current knowledge of laryngeal diseases. The gravity-free state does not seem to be a threat to the physiology of the larynx. A relatively nonspecialized medical team must be able to recognize and manage Earth-type diseases. They must also be capable of managing both the special problems associated with various degrees of decompression sickness and the increased possibility of inhaling a foreign body, which are inherent in the gravity-free state. In crew selection, a special attempt should be made to eliminate those members with an increased risk of laryngeal disease development. Simplified methods of examining the larynx, including flexible fiberoptic laryngoscopy, should be available. Airway management, including coaxial endotracheal intubation with a bivalved laryngoscope, would be possible. An audiovisual tape library of simple and moderately complex procedures would be highly valuable.

Intralaryngeal surgery 1977.

A very brief history of laryngoscopy and intralaryngeal surgery up to the present time is outlined. A simple comparison of some of the conventional laryngeal instruments with CO2 laser capability is made, and the common one-handed and two-handed surgical techniques are outlined. Four cases are presented, each of which demonstrates a significant feature of laryngoscopic surgery.

Variables in objective audiometry.

Objective audiometry has a definite application in evaluating problem patients. Three basic tests, electrodermal response audiometry (EDR), evoked cortical response audiometry (ERA), and impedance audiometry, are used to evaluate pediatric and adult patients. Each measurement technic, however, has limitations of which the physician should be aware. Impedance audiometry has the greatest potential as an objective measurement of auditory function.

Laryngoscopy in space travel.

The need for laryngoscopy aboard a spacecraft on a mission of one to three years is anticipated. Therefore, the inexperience of the potential endoscopists and the problems they face in the free-floating environment of space are considered. A simplified coaxial intubation technique employing a split-apart modification of a Jako-type laryngoscope is suggested.
