INTRODUCTION: Individuals with idiopathic subglottic stenosis (SGS) are at risk for voice disorders prior to and following surgical management. This study examined the nature and severity of voice disorders in patients with SGS before and after a revised cricotracheal resection (CTR) procedure designed to minimize adverse effects on voice function. METHOD: Eleven women with idiopathic SGS provided presurgical and postsurgical audio recordings. Voice Handicap Index (VHI) scores were also collected...

Idiopathic subglottic stenosis is a disease characterized by slow, progressive scarring and constriction of the subglottic airway. It almost always occurs in females between the 3rd and 5th decade of life. Symptoms are frequently misinterpreted as asthma and patients are referred for endoscopic evaluation only when asthma medications fail to alleviate their symptoms. Treatment options can be divided into endoscopic and open surgical techniques. Microlaryngoscopic scar reduction by laser followed by balloon dilation usually delivers good short-term results...

Herein, we described a novel method as the use of AcuBlade robotic microsurgery system to manage idiopathic subglottic stenosis in a 73 years old lady. Compared to traditional CO2 lasers, AcuBlade facilitated the scar resection by the generation of different shape of beams (straight, curved, or disk). The same setting used for phonomicrosurgery (1-mm beam length, power of 10 W and pulse duration of 0.05-s) allowed to obtain fast, long, and uniform cuts. In addition, the reduction of the number of laser passes over the same area prevented injury of adjacent tissue and thus reduced the risk of recurrence...

OBJECTIVES/HYPOTHESIS: Idiopathic subglottic stenosis (iSGS) is a rare and devastating extrathoracic obstruction involving the lower laryngeal and upper tracheal airway. It arises without known antecedent injury or associated disease process. Persistent mucosal inflammation and a localized fibrotic response are hallmarks of the disease. Despite the initial clinical description of iSGS more than 40 year ago, there have been no substantive investigations into the pathogenesis of this enigmatic and progressive airway obstruction...

OBJECTIVES/HYPOTHESIS: Idiopathic subglottic stenosis (iSGS) is an unexplained obstruction involving the lower laryngeal and upper tracheal airway. Persistent mucosal inflammation is a hallmark of the disease. Epithelial microbiota dysbiosis is found in other chronic inflammatory mucosal diseases; however, the relationship between tracheal microbiota composition and iSGS is unknown. Given the critical role for host defense at mucosal barriers, we analyzed tissue specimens from iSGS patients for the presence of microbial pathogens...

A 72-year-old female with a history of idiopathic subglottic tracheal stenosis suffered tracheal rupture during endoscopic balloon dilation. The defect measured 7.5 cm in length, through which the mediastinum was visualized. An 80 × 20-mm silicone-covered tracheobronchial stent was deployed over the defect. The patient was extubated subsequent to intraoperative computed tomography demonstrating minimal air escape. Postoperatively, the patient saw no further complications and was discharged 3 days later. The stent was removed 80 days postoperatively revealing healed trachea...

OBJECTIVES/HYPOTHESIS: Idiopathic subglottic stenosis (iSGS) is a rare and potentially life-threatening disease marked by recurrent and progressive airway obstruction frequently requiring repeated surgery to stabilize the airway. Unknown etiology and low disease prevalence have limited the ability to characterize the natural history of iSGS and resulted in variability in surgical management. It is uncertain how this variation relates to clinical outcomes. STUDY DESIGN: Medical record abstraction...

Laryngotracheal stenosis (LTS) is a rare condition that occurs most commonly as a result of instrumentation of the airway but may also occur as a result of inflammatory conditions or idiopathically. Here, we present the case of a patient who developed LTS as a complication of granulomatosis with polyangiitis (GPA), which was misdiagnosed as asthma for 6 years. After an admission with respiratory symptoms that worsened to the extent that she required intubation, a previously well 14-year-old girl was diagnosed with GPA...

REVIEW
C Sittel
Idiopathic subglottic stenosis is causing a narrowing of the central airway at the laryngotracheal junction. Etiology is remaining unclear at large. There is a marked preponderance for women in the fertile age, an association to estrogene or progesterone metabolism remains doubtful. Suggested treatment varies from repeated endoscopic interventions to primary open resection. Therapy selection in this heterogeneous condition should be based on the individual patient situation as well as surgeon's expertise. This complex entity is prone to complications and should preferably be managed in a referral center...
