Successful Treatment of Laryngeal Stenosis in Laryngo-Onycho-Cutaneous Syndrome with Topical Mitomycin C

PEDIATRIC DERMATOLOGY, Issue 1 2006
M.R.C.S., P. Seamus Phillips B.M.
It affects the skin, nails, and larynx. Laryngeal involvement may cause lethal airway obstruction, and has in the past proved very difficult to treat. Mitomycin C is an antibiotic that acts as an alkylating agent, inhibiting DNA synthesis. It reduces fibroblast proliferation, and has previously been used to treat choanal atresia and laryngeal stenosis. We report an 18-year-old man with complete transglottic laryngeal stenosis secondary to laryngo-onycho-cutaneous syndrome. An airway was established by dissection with a bougie and sickle knife, and was initially maintained by the upper limb of a Montgomery T-tube. Laryngeal granulation tissue present on removal of the T-tube was treated with topical mitomycin C (2 mg/mL) applied for 4 minutes on two occasions with an interval of 1 month. A year later, the airway remained patent, with no granulation tissue. [source]

Supracricoid laryngectomy with cricohyoidoepiglottopexy for advanced glottic cancer

Abstract Background. Supracricoid laryngectomy with cri-cohyoidoepiglottopexy (CHEP) is a conservative surgical procedure indicated in selected cases of advanced glottic carcinoma. Methods. This study is a review of our experience with 43 patients with T3/T4 glottic squamous cell carcinoma who underwent CHEP in our institution. All but two patients underwent selective neck dissections. All patients were staged on the basis of the 2002 TNM classification. Rates of recurrence and death were estimated by the Kaplan,Meier method. Results. The 5-year disease-specific survival and 5-year relapse-free survival rates were 78% and 83%, respectively. Neck metastases were found in three patients. Cartilage invasion occurred in 11 cases. The average length of hospital stay was 5.7 days. The mean time of enteral feeding tube was 33.8 days, and the mean time for tracheotomy was 29.6 days. Overall, normal swallowing was achieved in 74.4% of patients. Eleven patients had mild and major complications. Laryngeal stenosis emerged as the most frequent major complication. Three patients (6.9%) had local recurrences. Two patients (4.6%) had neck metastases. Conclusions. On the basis of this study, over a 7-year period with 43 patients with advanced glottic cancer, a successful on-cologic outcome is confirmed. © 2006 Wiley Periodicals, Inc.

Pediatric Laryngotracheal Obstruction: Current Perspectives on Stridor

THE LARYNGOSCOPE, Issue 7 2006
John Bent MD
Abstract Objectives/Hypothesis: To assess how medical advances have impacted the diagnosis, management, and outcomes of pediatric laryngotracheal obstruction, and to describe the advantages of audio-video documentation of stridorous children. Study Design and Methods: Retrospective. Methods and Materials: 268 patients were referred for suspected laryngotracheal obstruction during the 30 months between September 1, 1995 and March 1, 1998: 173 had 206 flexible fiberoptic laryngoscopies, and 160 had 273 direct laryngoscopies. One hundred and forty-one children were identified with laryngotracheal obstruction, yielding 40 different diagnoses that could be classified into 9 major categories. Thirty-six children (25.5%) had multiple sites of upper airway obstruction. Results: 138 children had follow-up >1 month. Twelve children died (8.7%), leaving 126 survivors (mean follow-up = 21.1 months). Outcomes were classified as resolved (44.2%), improved (37.0%), stable (9.4%), failed (0.7%), or death (8.7%). Better outcomes were seen in more readily treated diagnostic categories, such as tracheobronchial foreign body, chronic laryngitis, and suprastomal granulation tissue; laryngeal stenosis, tracheomalacia, and recurrent respiratory papillomatosis, had less favorable outcomes (P <.001). The former group also showed superior outcome compared to laryngomalacia (P <.001) and vocal cord mobility disorders (P = .004). Ninety-four patients (68.1%) had comorbidities complicating their management. Comorbid conditions were universal among deceased patients and least common in the resolved outcomes category (56.7%), supporting the premise that patients with poor outcomes are more likely to have comorbidities than patients with resolution of laryngotracheal symptoms (P = .034). Conclusions: Audio-video recording of pediatric laryngotracheal obstruction offers numerous advantages. Children classified into an array of diagnostic categories usually have favorable outcomes, but opportunities for continued advances exist, particularly regarding management of comorbidity and chronic obstruction.
