Intervention model: PARALLEL
Primary purpose: TREATMENT

Brief summary: Total arytenoidectomy is claimed to increase risk of aspiration and cause more voice loss than other operations performed for bilateral vocal fold paralysis (BVFP). However, objective evidence for such conclusion is lacking. There is no study comparing swallowing and voice after total and partial arytenoidectomy.

Detailed description: Design: Prospective, randomized, double-blind, case-control Setting: Tertiary, referral, university Patients: Twenty patients with BVFP Intervention: Endoscopic total and partial arytenoidectomy

Eligibility criteria: Inclusion Criteria:

* Bilateral vocal fold paralysis

Exclusion Criteria:

* Previously operated patients

Primary outcomes:
measure: Decannulation
timeFrame: From the day of operation until 52 weeks after arytenoidectomy
Secondary outcomes:
measure: Duration of operation
timeFrame: At the day of operation
Other outcomes:
measure: Voice Handicap Index
timeFrame: From the day of operation until 52 weeks after arytenoidectomy
measure: Acoustic analysis

timeFrame: 52 weeks after arytenoidectomy
measure: Subjective comparison of pre- and postoperative voice by a phoniatrician
timeFrame: From the day of operation until 52 weeks after arytenoidectomy
measure: Speech intensity
timeFrame: 52 weeks after arytenoidectomy
measure: Functional outcome swallowing scale
timeFrame: 52 weeks after arytenoidectomy
