Lye burn larynx quiz: laryngoplasty repair essentials
Quick, free laryngoplasty repair quiz with case-based questions. Instant results.
This quiz helps you practice decisions for lye burn of the larynx and laryngoplasty repair, from airway assessment to aftercare. For a fast anatomy tune-up, try the larynx labeling quiz, and build scope skills with the bronchoscopy and laryngoscopy quiz. You can also refine plans with the tracheal intubation quiz.

Cheat Sheet
- Classification and Depth Assessment -
The classification of lye burn of the larynx repaired by laryngoplasty follows a depth-based system similar to skin burns: superficial (mucosal), partial-thickness (submucosal), and full-thickness (cartilage involvement). Use the "3D" mnemonic - Depth, Degree, Decision - to quickly recall injury severity and guide timing for reconstruction. Accurate endoscopic grading (e.g., narrow-band imaging) is crucial for preventing long-term stenosis.
- Timing of Reconstruction -
Early airway management with intubation and steroids reduces acute edema, but definitive laryngoplasty is optimally delayed 3 - 6 months post-injury to allow inflammation resolution and stable granulation. This staged approach - initial airway stabilization followed by cartilage grafting - is derived from Joshi et al. (Laryngoscope 2019). Questions on timing frequently appear in laryngeal burn treatment quizzes, distinguishing emergent from elective repair.
- Cartilage Graft Selection and Technique -
Autologous costal cartilage is the gold standard for structural support in laryngoplasty due to its low resorption and high availability. The CART mnemonic - Cartilage, Alignment, Rehydration, Tension - helps recall graft preparation steps before securing it to the thyroid - cricoid framework. Recognizing graft types and fixation methods is essential for laryngoplasty procedure questions in ENT surgery knowledge tests.
- Airway Stenting and Postoperative Management -
Maintaining patency with a stent (e.g., Montgomery T-tube) for 4 - 8 weeks supports graft integration and prevents restenosis. Scheduled endoscopic assessments and gentle suctioning protocols minimize granulation and promote healing. Mastery of stenting principles is a common focus in larynx injury repair quizzes to ensure safe decannulation.
- Functional Outcome and Rehabilitation -
Postoperative evaluation uses videolaryngoscopy, spirometry (FEV/PEF), and acoustic voice analysis to assess airway clearance and phonatory function. The VOICE mnemonic - Ventilation, Oropharyngeal function, Inhalation - Exhalation balance, Communication exercises, Evaluation intervals - aids in structuring rehabilitation. Comprehensive tracking of these metrics is emphasized in ENT surgery knowledge tests for holistic laryngeal burn treatment.
