Extended laryngofissure in the management of subglottic stenosis in the young child: a preliminary report.

The child with subglottic stenosis and a tracheotomy is a management problem. To date, a consistent method for successful and expeditious correction of the primary lesion to permit decannulation has eluded clinicians. The child is tracheotomized and thus frequently hospitalized for a lengthy period. Personal development and family relationships are adversely affected and the mortality rate during this period of cannulation is significant. During the past eighteen months in an attempt to achieve earlier decannulation, three children with subglottic stenosis have undergone a surgical procedure in which division of the anterior and posterior aspects of the cricoid ring are the key surgical maneuvers.

[Problems presented by closed laryngeal-tracheal injuries].

The authors consider the problems raised by severe closed laryngotracheal trauma and report 4 cases. -the immediate tisk to life is due to direct involvement of the respiratory tract requiring emergency measures including cardiorespiratory resuscitation in cases of acute asphyxia. -the origin of the initial respiratory distress, if not obvious from the start, may be suspected in view of the difficulties or impossibility of tracheal intubation, which is also liable to aggravate lesions due to trauma. It is one of these rare cases of resuscitation where emergency tracheotomy is essential. It permits also early, precise surgical exploration. -in cases of fracture of the larynx, a wound of the trachea or rupture and separation of the trachea, the reconstruction must be constructiononstruction must be considered within the first 48 hours. Provision of food and resting of the larynx may be conciliated by installing an esophageal catheter or performing a gastrostomy. Benign trauma, such as contusion or laryngeal commotion, requires close supervision association with medical treatment designed to prevent the onset of lesional oedema.

[Aortopexy for tracheomalacia in infants and children].

During the past 12 years (1985-1998), 28 infants and children were operated on here for tracheomalacia. The diagnosis was made in all using rigid bronchoscopy. During the examination the infants breathed spontaneously, but the trachea collapsed on forced expiration. Indications for surgery were repeated cyanotic spells ("dying spells") in 22, recurrent pneumonia, and inability to extubate (in 8). In 11 there were more than 1 indications. Age at surgery was from 7 days to 3 years (average 11.7 months). All 28 children underwent bronchoscopy and guided aortopexy via a left-third intercostal approach. The ascending aorta and aortic arch (and in 6 the proximal innominate artery as well) were lifted anteriorly, using 3-5 non-absorbable sutures (5.0). The sutures were placed through the adventitia of the great vessels and then passed through the sternum. Respiratory distress was significantly improved in 21. Another 2 required external tracheal stenting with autologous rib grafts, and in 1 other an internal Palmaz stent was introduced for tracheal stability. In 4 aortopexy failed, 1 of whom had tracheobronchomalacia throughout, and another 3 had laryngomalacia which required tracheostomy to relieve the respiratory symptoms. Postoperative complications were minor: pericardial effusion in 1 and relaxation of the left diaphragm in another. 1 infant subsequently died, of unknown cause 10 days after operation, after having been extubated on the 1st postoperative day. On long-term follow-up (6 months to 12 years) 25 were found free of residual respiratory symptoms and 3 remained with a tracheostomy. Thus, infants and children with severe tracheomalacia associated with severe respiratory symptoms, can be relieved by bronchoscopic guided suspension of the aortic arch to the sternum.

Scanning electron microscopic study of the muscle fiber ends at the myotendinous junction in the posterior cricoarytenoid and cricothyroid muscles in rats.

The fine structural organization of muscle fiber ends at the myotendinous junction in the posterior cricoarytenoid (PCA) and cricothyroid (CT) muscles in adult rats was studied by scanning electron microscopy, after removal of tendon connective tissues using the HCI-hydrolysis method. The muscle fiber ends in the PCA muscle had a relatively simple conical appearance and contained a great number of longitudinal slits on the surface. In the CT muscle, the muscle fiber ends were classified into two types. One type had a conical appearance similar to the PCA muscle with many slits on the surface, while the other type was characterized by a complex arrangement of cylindrical cytoplasmic processes and deep clefts, as seen in common skeletal muscles. These findings suggest that the PCA muscle is evolutionarily primitive, and that the CT muscles represent a transitional form between primitive and evolved muscles.

[Translaryngeal microsurgical arytenoidectomy].

The authors describe a microsurgical procedure for translaryngeal arytenoidectomy in bilateral vocal cord paralysis and relate their clinical experience. They consider this approach as very valuable in as much as a rather minimal surgical procedure will create a good airway while conserving a satisfactory vocal function.

[The arthritis of the cricoarytenoid joint, a rare postintubation complication and its novel treatment (author's transl)].

A case of aphonia following a long-time endotracheal intubation is presented. The paramedian position of the left and the incomplete adduction of the right vocal cord were caused by a complete, respectively partial ankylosis of the cricoarytenoid joints. The ankylosis was the result of an arthritis during the intubation period. A nearly normal mobility of the vocal cords and a normal voice was achieved by translaryngeal injections of Fludrocortisone and Hyaluronidase into the cricoarytenoid joints and by their passive mobilisation.

[Critical points for success in supracricoid partial laryngectomy with cricohyoidepiglottoepexy].

Cancer of the larynx is a relatively rare neoplasia in Mexico as well as in the rest of the world; however, evolution of treatment in recent years showed important results in terms of survival and local control. Supracricoid partial laryngectomy with cricohyoidoepiglottopexy is a surgical technique that permits similar oncologic results to other conservatives techniques for glottic carcinoma, with excellent functional results. The objective of the present work was to show the critical points of the technique based on the description of Laccourreye, emphasizing the anatomical aspect of resection and reconstruction to avoid complications and achieve best results.
