“…8,9 Use of controlled low pressure, large volume, nontraumatic endotracheal and tracheostomy cuffs and deflating cuff every two hourly for 5 to 10 minutes has decreased the incidence of intubation injuries. 6 Microlaryngoscopy and dilatation with local steroid, mitomycin-c give a good result in subglottic stenosis due to Wegener's granulomatosis. postprocedure, patient was tolerating tracheostomy full block well.…”

Our aim is to highlight the possibility of subglottic stenosis caused by Wegener's granulomatosis. The incidence of subglottic stenosis in Wegener's granulomatosis is seen five times more often in children.We report a case of a 12-year-old female diagnosed as Wegener's granulomatosis who was on medical treatment since six months. She presented to us with stridor. As rigid laryngoscopy revealed a pinhole opening in the subglottic region, an emergency tracheostomy was performed. This was followed by a planned microlaryngoscopy using cold steel instruments. A triradiate incision with dilatation, local steroid injection and topical application of mitomycin-c was performed. In Wegener's granulomatosis, subglottic stenosis is caused due to vasculitis therefore, the use of laser and stent is contraindicated, as this may lead to a further worsening of the stenosis.Among various causes of subglottic stenosis, the most common cause is use of cuffed tracheostomy tube and endotracheal tube. It is essential to diagnose the etiology of subglottic stenosis to decide on the appropriate modality of treatment.

Objectives Supraglottic stenosis is a rare type of laryngeal stenosis that is caused by congenital laryngotracheal anomalies, iatrogenic instrumentation injuries, autoimmune disorders, infection, irradiation, chemical or thermal burns, and external blunt or penetrating trauma. The author presents his experience on nine patients using this new endoscopic surgical technique for treatment of supraglottic stenosis. Study Design Individual retrospective cohort study, tertiary referral center, university hospital. Methods All cases of supraglottic laryngeal stenosis treated during a 10‐year period at a tertiary academic medical center were reviewed. Nine patients with supraglottic stenosis treated with endoscopic uni‐ or bilateral z‐plasty technique were determined and presented. The etiology of stenosis was iatrogenic surgical trauma in seven patients, laryngeal fracture in one patient, and systemic lupus erythematosus in the other patient. Main outcome measures were respiratory function test results, absence of dyspnea on exertion, and decannulation if tracheotomy was present preoperatively. Results Seven patients with tracheotomy were decannulated 1 month after surgery. All nine patients had adequate airway and were dyspnea‐free. Their preop respiratory function test results improved significantly postoperatively (P < .05). Conclusion For supraglottic stenosis endoscopic surgery using mucosal flaps in the form of z‐plasty should be considered within the available surgical techniques. Although this type of surgery is highly successful, it is technically difficult to apply. Level of Evidence 4 Laryngoscope, 131:E534–E539, 2021

Morphometric Study of the Growth of the Subglottis after Interruption of the Circular Structure of the Cricoid

In young rabbits the growth of the subglottis was studied over a period of 20 weeks after interruption of the circularity of the cricoid on the ventral side. In all cases the cricoid developed into a U-like structure which did not cause an airway narrowing. However, a cricoid lesion combined with an injury to the soft tissue lining led up to a subglottic stenosis. It was concluded that when the soft tissue layer is undamaged, an intact circular structure of the cricoid is not compulsory for the normal development of the subglottis.
