A comprehensive collection of clinical calculators and tools organized by subspecialty to assist Otolaryngologists and healthcare professionals in daily practice and decision-making.
Specialized tools for pediatric airway management and procedural planning
Age-based bronchoscope sizing (2.5-6.0mm) with ETT, LMA, and suction catheter recommendations for pediatric bronchoscopy procedures.
Use ToolCalculate optimal ETT insertion depth (cm at lip) using age-based formula (age/2 + 12) or weight-based method for pediatric intubation.
Use CalculatorRacemic epinephrine dosing (0.05 mL/kg, max 0.5 mL) for croup and airway edema with dilution instructions and administration guidelines.
Use CalculatorCotton-Myer grading (I-IV) calculator for subglottic stenosis based on ETT size reduction with percentage obstruction and surgical planning guidance.
Use CalculatorAge-specific balloon catheter sizing (4-20mm) for laryngotracheal stenosis dilation with pressure recommendations and technique guidelines.
Use CalculatorVisual atlas of normal bronchoscopic anatomy, congenital variations (tracheomalacia, laryngomalacia), and pathological findings with clinical images.
View GuideComprehensive calculators for cochlear implants, hearing aids, and audiometric evaluations
Cochlear implant screening using validated FDA criteria: high-frequency PTA ≥65 dB HL and word recognition score ≤70% in best-aided condition.
Use CalculatorCalculate 3-frequency (500/1000/2000 Hz), 4-frequency (500/1000/2000/4000 Hz), and high-frequency (2000/4000/8000 Hz) pure tone averages with automatic hearing loss classification.
Use CalculatorDetailed comparison of cochlear implant systems from Advanced Bionics, Cochlear, and MED-EL including processor features, electrode arrays, and MRI compatibility.
View ComparisonCompare major hearing aid manufacturers (Phonak, Widex, Oticon, ReSound, Starkey, Signia) with NAL-NL2 vs DSL v5 fitting formula comparison.
View ComparisonAssessment tools for chronic rhinosinusitis and sinonasal quality of life
Sino-Nasal Outcome Test: 22-item validated questionnaire (0-110 scale) for chronic rhinosinusitis symptom assessment and treatment response tracking. Clinically meaningful difference ≥8.9 points.
Use CalculatorVoice and laryngopharyngeal reflux assessment instruments
Validated voice quality-of-life assessment with VHI-10 (0-40 scale) and VHI-30 (0-120 scale) versions covering functional, physical, and emotional voice impact domains.
Use Calculator9-item laryngopharyngeal reflux screening tool (0-45 scale). Score >13 suggests LPR. Includes hoarseness, throat clearing, dysphagia, and heartburn assessment.
Use CalculatorObstructive sleep apnea screening and airway assessment tools
8-item validated questionnaire (0-24 scale) for excessive daytime sleepiness screening. Score >10 indicates abnormal sleepiness; >16 suggests severe sleep disorder.
Use CalculatorMallampati classification (I-IV) for intubation difficulty and Friedman staging (I-IV) for OSA surgical planning based on tonsil size, palate position, and BMI.
Use ToolMedical calculators and dosing tools for general otolaryngology practice
BMI, BSA, ideal body weight, fluid requirements, and other general medical calculations commonly used in ENT practice.
View CalculatorsIncobotulinumtoxinA reconstitution calculator with dilution ratios, concentration tables, and indication-specific dosing for laryngeal dystonia and spasmodic dysphonia.
