OBJECTIVE To conduct an endoscopic and histologic analysis of the subglottic effects of various carbon dioxide laser-induced injuries in the rabbit model. DESIGN Animals were assigned to either a control (cricothyroidotomy only) group or 4 (cricothyroidotomy and posterior subglottic laser) groups that were injured using varying systematically controlled carbon dioxide laser power exposures (5...

Acquired subglottic stenosis (a SGS) continues to pose great challenge to patients and clinicians due to lack of effective treatment strategies. Our understanding in pathophysiology of a SGS has significantly advanced in the past decades; however, much still remains to be elucidated. The purpose of this review is to describe current state of research in acquired subglottic stenosis, and discuss...

Introduction. Respiratory failure followed by endotracheal intubation can lead to severe post intubation laryngeal lesions in small group of patients. Complikations are classified as acute (early) and chronic on a base the laryngoscopy findings. Aim. To assess the statistical relationship between early post intubation complications and intubation duration, birth weight and gestational age. Mate...

BACKGROUND Recent studies have challenged the historically accepted fact that the larynx is cone-shaped in infants and children. The present study used computed tomography (CT)-based measurements to evaluate airway dimensions. The purpose of this investigation was to determine the dimensional transition between the subglottic area and the cricoid ring in children. METHODS This is a retrospect...

BACKGROUND Although clinical studies of the high-flow nasal cannula (HFNC) and its effect on positive end-expiratory pressure (PEEP) have been done, the washout effect has not been well evaluated. Therefore, we made an experimental respiratory model to evaluate the respiratory physiological effect of HFNC. METHODS An airway model was made by a 3D printer using the craniocervical 3D-CT data of...

We assessed several factors which might be responsible for the recurrence of post-intubation airway stenosis in a large group of patients who underwent resection and reconstruction surgery by one surgical team. Four hundred and ninety-four patients underwent reconstruction of post-intubation airway stenosis during 1995-2006. The case group comprised patients who had developed recurrence, while ...

OBJECTIVES/HYPOTHESIS To investigate and treat the late complications of using nickel-titanium alloy stents in laryngotracheal, bronchial, and esophageal stenosis patients who developed severe laryngotracheal stenosis (SLS). STUDY DESIGN Retrospective clinical study. METHODS Thirteen patients with SLS or tracheoesophageal fistula secondary to insertion of a nickel-titanium alloy stent for t...

Introduction: Idiopathic subglottic tracheal stenosis is a rare inflammatory disease of the trachea; most commonly affects females within the age range of 20-50 years. No etiologic factor has yet been identified for this rare tracheal disease and therefore it should be diagnosed after the exclusion of other inflammatory, traumatic, and autoimmune diseases of the trachea. The familial or g...

OBJECTIVE To show changes in the management of subglottic laryngitis over the last twenty years in Croatia. METHODS We sent questionnaires to paediatricians and otolaryngologists (ENT) in 9 Croatian hospitals in 1993, 2003 and 2013. In the questionnaire we presented a case of a child with moderately difficult subglottic laryngitis, after which they had to answer questions about the management...

Subglottic hemangioma is a rare, histologically benign congenital neoplasm. The natural history is characterized by progressive obstruction of the airways during the proliferative stage, followed by gradual regression of the obstructive symptomatology in the involutional phase. After an asymptomatic neonatal period, the infant presents a characteristic biphasic stridor as the lesion progressive...
