What is the next step in managing an elderly patient with a 3-month history of idiopathic Vocal Cord (VC) palsy, who had one episode of aspiration pneumonia, and a scan that did not show any abnormalities?

Management of Idiopathic Vocal Cord Palsy with Aspiration Pneumonia

For an elderly patient with 3-month idiopathic vocal cord palsy who has experienced aspiration pneumonia, the next step is medialisation thyroplasty (option b), as early intervention (within 6 months) improves long-term vocal outcomes and reduces the need for more invasive procedures, while simultaneously addressing the aspiration risk that has already manifested clinically. 1

Rationale for Early Surgical Intervention

Early medialization creates a more favorable vocal fold position for phonation that can be maintained by synkinetic reinnervation, in contrast to the final position of a lateralized vocal fold being determined solely by reinnervation. 1 The evidence demonstrates that:

• Patients who received vocal fold injection or medialization early (<6 months) had decreased need for more invasive long-term therapy compared to those treated late (>6 months) 1
• Patients with unrecovered vocal fold paralysis who had temporary injection medialization were statistically less likely to ultimately require permanent surgical intervention compared to conservative management alone 1
• At 3 months post-onset with documented aspiration pneumonia, this patient has both failed conservative management and demonstrated significant morbidity requiring definitive intervention 1

Why Not the Other Options

EMG (Option e) - Not Appropriate at This Stage

• EMG would have been useful earlier in the course to assess prognosis for spontaneous recovery 1
• At 3 months with aspiration pneumonia already documented, the priority is preventing further pulmonary complications, not prognostication 1
• The patient has already demonstrated clinical failure with aspiration pneumonia, making further observation inappropriate 1

SALT/Speech Therapy (Option c) - Insufficient Alone

• While speech and language therapy has a role in dysphagia management, this patient has already progressed to aspiration pneumonia despite 3 months of presumed conservative management 1
• History of aspiration pneumonia is a significant risk factor (OR 7.00, p<0.001) for developing further pneumonia even with proper swallowing modifications 1
• Performance status and PAS score ≥3 are independent predictors of pneumonia development despite conservative measures 1

Calcium Hydroxyapatite Injection (Option a) - Temporary Measure

• While injection medialization can be effective, medialization thyroplasty provides more definitive and adjustable correction 1, 2
• The patient has already demonstrated severe consequences (aspiration pneumonia) requiring more definitive intervention 3
• Injection may be considered if the patient is too high-risk for thyroplasty, but this is not indicated in the question 4

Selective Reinnervation (Option d) - Not First-Line

• Reinnervation procedures are typically considered for specific indications and are not the standard first approach for aspiration prevention 1
• Medialization thyroplasty has a well-established safety profile with only 10.5% total complications and 4.5% major complications in a systematic review of 2,426 patients 2

Clinical Evidence Supporting Medialization Thyroplasty

Medialization thyroplasty is highly effective for preventing aspiration with a favorable safety profile:

• In patients with severe chronic aspiration, bilateral medialization thyroplasty resulted in complete cessation of aspiration in all treated patients 3
• The procedure maintains good voice quality while addressing aspiration risk 3
• Same-day discharge occurred in 429 patients without associated adverse events, demonstrating excellent safety 2
• Most common complications are minor: nonobstructive hematoma (2.4%) and hemorrhage (1.5%) 2

Critical Clinical Context

The presence of aspiration pneumonia in a patient with vocal cord paralysis represents a significant quality of life and mortality risk that demands intervention:

• Impaired laryngeal sensation (present in many VC palsy patients) is strongly associated with penetration-aspiration (OR 5.01, p<0.001) 1
• History of aspiration pneumonia is the strongest predictor of recurrent pneumonia (adjusted OR 7.00, p<0.001) even with dietary modifications 1
• Vocal cord paralysis predisposes to dangerous aspiration scenarios requiring definitive management 5, 6

Important Caveats

• If the patient has significant medical comorbidities making surgery high-risk, temporary injection medialization with calcium hydroxyapatite could be considered as a bridge procedure 1, 4
• The procedure should be performed by an experienced laryngologist, as proper technique and implant positioning are critical for success 2
• Post-operative speech therapy should still be incorporated as adjunctive treatment to optimize swallowing function 1

The combination of 3-month duration (within the optimal early intervention window), documented aspiration pneumonia (demonstrating clinical failure of conservative management), and negative imaging (ruling out treatable structural causes) makes medialisation thyroplasty the definitive next step for this patient. 1, 2
