Abstract

Unilateral Vocal cord palsy typically presents with dysphonia, shortness of breath and swallowing difficulty. It can be iatrogenic, idiopathic or may occur secondary to damage to recurrent laryngeal nerve following trauma, impinging mass lesions, neurological disorders or neuro-musculoskeletal diseases, or infectious in aetiology. To study and compare the effects of Type I Thyroplasty depending on the time of presentation, that is, early and delayed presentation. Ambispective Study Design. Our study included 32 patients who presented to our Institution with history of dysphonia, diagnosed with unilateral vocal cord palsy. Depending on the duration of symptoms on presentation, patients were categorised into 2 groups, which is early subgroup who presented within 1 year of symptom onset, 21 patients and delayed subgroup who presented after 1 year of symptom onset, 11 patients. Complete preoperative evaluation including perceptual analysis of voice quality, acoustic measures of voice quality, Aerodynamic measures of voice quality, quality of life measure, tele laryngoscopy was done. All patients underwent Type I Thyroplasty and were followed up at 2 weeks, 1 months, 3 months and 6 months, with follow up criteria including perceptual analysis of voice, MPT and VHI-10. Out of 32 patients, Male to female ratio was 26 : 6, with mean age of presentation being 47 years. The laterality of the palsy was R: L → 4: 28. When compared to the Delayed subgroup, early Subgroup had significant improvement in outcomes with respect to GRBAS Scale, VHI-10 and MPT.
