Laryngeal Hypermobility with Clicking After Head Turning
You need direct laryngeal visualization with laryngoscopy to establish the diagnosis, as this presentation of clicking and hypermobile sensation in the larynx after trauma requires anatomical assessment to rule out structural injury and identify the specific cause. 1
Immediate Evaluation Approach
Perform or refer for laryngoscopy now rather than waiting 4 weeks, because this represents an acute traumatic event with persistent mechanical symptoms. 1 The 2018 AAO-HNS guidelines explicitly state that laryngoscopy should be performed "irrespective of duration if a serious underlying cause is suspected," and acute trauma with mechanical symptoms qualifies. 1
Key History Elements to Document:
- Exact mechanism of head turning (speed, direction, force)
- Presence of respiratory distress or stridor (requires immediate evaluation) 1
- Voice quality changes (hoarseness, pitch alterations, vocal effort changes)
- Pain location and radiation patterns
- Swallowing difficulties or clicking with deglutition
- Professional voice use status
Physical Examination Specifics:
- Palpate the laryngeal framework during swallowing to localize clicking source 2
- Assess for tenderness over hyoid bone and thyroid cartilage
- Check distance between hyoid and thyroid cartilage superior cornua
- Evaluate for neck masses or asymmetry
- Test for hypermobility of laryngeal structures with gentle lateral pressure
Diagnostic Workup
Do NOT obtain CT or MRI before laryngoscopy 1 - this is an explicit recommendation against imaging prior to laryngeal visualization, as it delays diagnosis and increases costs without improving outcomes.
After Laryngoscopy:
If clicking persists and laryngoscopy shows normal vocal fold function but mechanical symptoms continue, then consider swallowing CT with 3D reconstruction or virtual reality imaging 3. This advanced imaging has proven diagnostic value for clicking larynx syndrome by visualizing dynamic collision between:
- Thyroid cartilage superior cornua and hyoid bone 3, 2
- Hyoid greater cornua and cervical spine 4
- Abnormally positioned or elongated laryngeal structures 5
Most Likely Diagnoses
Based on your acute presentation after head turning:
- Clicking Larynx Syndrome - collision between thyroid cartilage superior cornua and hyoid bone during movement 2, 4
- Hyoid Bone Syndrome - elongated or displaced greater horn of hyoid 5
- Laryngeal cartilage subluxation - traumatic displacement from sudden head rotation 6
Treatment Algorithm
Conservative Management (First-Line):
- Observation for 4-6 weeks if no voice changes, breathing difficulty, or severe pain
- Avoid repetitive neck movements that trigger clicking
- NSAIDs for inflammation if painful
- Do NOT use antibiotics, corticosteroids, or antireflux medications empirically 1 - these are explicitly contraindicated without laryngoscopic diagnosis
Surgical Intervention Indications:
If symptoms persist beyond conservative management and imaging confirms structural abnormality:
- Thyroplasty with resection of superior thyroid cornua (most common procedure) 2
- Hyoid bone greater cornu resection if hyoid pathology identified 5
- Surgery provides immediate and complete symptom relief in reported cases 2, 4
Critical Pitfalls to Avoid
Do not dismiss this as psychogenic - clicking larynx is a real anatomical condition that health professionals often misattribute to psychological causes 2. The mechanical nature of your symptoms (clicking, grinding, hypermobility after specific trauma) strongly suggests structural pathology.
Do not delay if you develop:
- Progressive hoarseness
- Breathing difficulty or stridor
- Inability to swallow
- Severe or worsening pain
These require immediate ENT evaluation. 1
Special Consideration
If you have joint hypermobility elsewhere in your body, consider evaluation for hypermobile Ehlers-Danlos syndrome or hypermobility spectrum disorders, as these patients have significantly increased prevalence of laryngeal dysfunction symptoms (27% vs 14.9% in controls) 7.
Bottom line: Get laryngoscopy within days to weeks, not months. If normal vocal folds but persistent clicking, proceed to swallowing CT with 3D reconstruction. Surgery is definitive if conservative management fails and anatomical cause is identified.
