Which layer is involved in a full-thickness laryngeal burn injury?
Only the mucosal layer
Submucosal tissue without cartilage involvement
Epiglottic fold only
Cartilage of the laryngeal framework
Full-thickness laryngeal burns extend through the mucosa and submucosa into the cartilage, reflecting severe injury requiring rigorous repair.
True or False: Definitive laryngoplasty is ideally performed immediately following the acute laryngeal burn phase.
False
True
Definitive laryngoplasty is typically delayed 3 - 6 months post-injury, after acute inflammation resolves, for optimal outcomes.
Which classification system is most useful for grading the depth of laryngeal burns?
3D: Depth, Degree, Decision
Rule of Nines
Parkland formula
Cincinnati airway protocol
The '3D' mnemonic - Depth, Degree, Decision - guides the evaluation and staging of laryngeal burn severity.
What is the gold standard graft material for structural support in laryngoplasty following laryngeal burns?
Synthetic mesh
Auricular cartilage
Autologous costal cartilage
Porcine-derived scaffolds
Autologous costal cartilage is preferred for its strength, availability, and minimal resorption in reconstruction.
True or False: Stenting is usually avoided in laryngoplasty procedures for laryngeal stenosis.
True
False
Stenting is commonly employed to maintain airway patency and reduce restenosis risk after laryngoplasty.
Which imaging tool assists with endoscopic assessment of laryngeal burn depth?
Electrocardiogram
Non-contrast CT of the brain
Narrow-band imaging (NBI)
Chest X-ray
NBI enables detailed visualization of mucosal changes and helps grade injury severity in laryngeal burns.
Postoperative stenting in laryngoplasty is typically maintained for how long?
24 - 48 hours
1 - 2 weeks
4 - 8 weeks
Over 1 year
Stenting for 4 - 8 weeks supports healing, completes graft integration, and prevents restenosis post-surgery.
True or False: Acoustic voice analysis is part of postoperative evaluation after laryngoplasty.
True
False
Acoustic voice analysis helps assess phonatory function and rehabilitation success after reconstruction.
Which feature is LEAST likely in a patient with acute lye burn of the larynx?
Stridor
Dysphagia
Hoarseness
Chronic otitis media
Chronic otitis media is unrelated to acute laryngeal chemical burns, which primarily cause airway and voice changes.
What is the main goal of initial airway management in a severe laryngeal burn?
Immediate definitive laryngoplasty
Placement of a permanent tracheostomy
Oral antibiotics alone
Stabilize airway via intubation and control edema
Early stabilization using intubation and steroids is vital to manage acute airway compromise before definitive surgery.
True or False: Costal cartilage grafts used in laryngoplasty are prone to rapid resorption.
True
False
Autologous costal cartilage has low resorption rates, making it the preferred graft for airway reconstruction.
Which of the following is a complication of improper stenting post-laryngoplasty?
Renal calculi
Peripheral neuropathy
Granulation tissue formation
Acute hepatitis
Granulation tissue can develop if stenting is not optimally managed, potentially leading to restenosis.
According to the VOICE mnemonic, what does 'V' stand for in postoperative rehabilitation?
Vagus nerve monitoring
Ventilation
Volume measurement
Vocalization exercises
'V' in VOICE highlights the need to assess and monitor ventilation during rehab after laryngoplasty.
True or False: All cases of laryngeal burns require immediate surgical reconstruction.
False
True
Not all burns need immediate surgery. Superficial injuries may heal with conservative management, while severe cases need staged reconstruction.
Which of the following is NOT a recommended step in preparing a cartilage graft (CART mnemonic)?
Cartilage selection
Rehydration and setting correct tension
Antibiotic soaking for 72 hours
Alignment with the airway
Antibiotic soaking for 72 hours is not standard; the CART mnemonic refers to Cartilage, Alignment, Rehydration, and Tension.
Which postoperative tool is routinely used to assess airway patency following laryngeal graft repair?
Spirometry (FEV1/PEF)
Blood glucose monitoring
Bone density scan
Fundoscopy
Spirometry evaluates functional ventilation and is key for assessing airway patency after surgery.
True or False: The most common cause of restenosis after laryngoplasty is recurrent cancer.
True
False
Restenosis typically results from scar tissue or granulation, not recurrent malignancy, post-laryngoplasty.
In laryngeal burn healing, what is a primary benefit of gentle suctioning protocols post-surgery?
Reducing aspiration risk and granulation formation
Accelerating cartilage resorption
Lowering cholesterol levels
Preventing vocal fold paralysis
Gentle suctioning helps keep the airway clear, minimizing granulation tissue and facilitating healing.
Which clinical sign suggests successful functional outcome after laryngoplasty for laryngeal burns?
New onset dysphagia
Constant cough and aspiration
Improved phonatory function and airway clearance
Persistent stridor on exertion
A successful outcome is indicated by restored airway clearance and improved voice function without new complications.
True or False: Oropharyngeal function must be incorporated into rehabilitation after laryngoplasty.
True
False
Oropharyngeal function (swallowing and airway protection) is essential in rehabilitation to ensure comprehensive recovery post-laryngoplasty.

Cheat Sheet

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.
