The course of Wegener granulomatosis has been dramatically improved by daily treatment with cyclophosphamide and glucocorticoids. Nonetheless, disease- and treatment-related morbidity is often profound. Alternative forms of therapy have not yet achieved the high rates of remission induction and successful maintenance that have been reported with daily cyclophosphamide treatment. Despite continued therapeutic success with cyclophosphamide, our long-term follow-up of patients with Wegener granulomatosis has led to increasing concerns about toxicity resulting from prolonged cyclophosphamide therapy and has encouraged investigation of other therapeutic regimens.

Objective. To determine the clinical features and optimal treatment of subglottic stenosis (SGS) in patients with Wegener's granulomatosis (WG). Methods.Review of 43 patients with SGS and treatment of 20 patients with intratracheal dilationglucocorticoid injection therapy.Results. SGS developed in 43 of 189 patients with WG who were followed up at the National Institutes of Health Clinical Center. The diagnosis of SGS occurred in the absence of other features of active WG in 21 of 43 patients (49%). In 21 patients (49%), SGS began while the patient was receiving systemic immunosuppressive therapy for disease activity involving other sites. Tracheostomy was required in 10 of 18 patients (56%) who were treated with systemic immunosuppressive therapy. In 20 patients treated with intratracheal therapy, none required tracheostomy and 6 with previous tracheostomies were decannulated.Conclusion. SGS often occurs independently of other features of active WG and is frequently unresponsive to systemic immunosuppressive therapy. Intratracheal dilation-injection therapy provides a safe and effective treatment for WG-associated SGS and, in the absence of major organ disease activity, should be used

Wegener's granulomatosis (WG) is a multisystem inflammatory disease characterized by vasculitis, granuloma formation, and necrosis. Among 158 patients treated at the National Institutes of Health during the past 24 years, 145 (92%) had an otolaryngologic manifestation of their disease and 25 (16%) had subglottic stenosis (SGS). SGS varied from asymptomatic to life-threatening. Sixteen (80%) of 20 patients with fixed SGS required surgical intervention, including manual dilations, carbon-dioxide laser resections, and laryngotracheoplasty (LTP). LTP was performed with and without microvascular reconstruction. Thirteen of the patients required tracheostomy and all 13 were ultimately decannulated. Five patients who repeatedly failed dilations and/or endoscopic laser surgery underwent LTP. Since 1987, two patients have undergone LTP with microvascular free flaps. Both patients were subsequently decannulated. The authors' experience demonstrates that management of SGS in WG is complex, requiring individualized frequent multimodality interventions to achieve satisfactory results. Microvascular laryngotracheal reconstruction should be considered in the surgical armamentarium for patients with persistent stenoses.

Spray cryotherapy was a safe adjunct modality to accomplish airway patency in patients with benign tracheal stenosis. Although efficacy evidence is limited for SCT, it may be useful for patients who have experienced treatment failure with conventional modalities. Further analysis of this cohort will determine the physiologic durability of the reported short-term changes. Additional trials are warranted for further evaluation of this modality.
