Select and explain.

C: Type I thyroplasty
Answer: C: Type I thyroplasty 
Explanation: (c) Type I thyroplasty(Ref. Current Diagnosis & Treatment Otolaryngology, Lalwani, 3rd ed., 478)Stridor means B/L RLN palsy. Glottic gap being 3mm so VC are in paramedian position. So the management is tracheostomy followed by lateralisation of the VC by type II thyroplasty or Cordectomy. Type I thyroplasty means doing medialisation of VC which will aggravate the condition.
