A COMPARATIVE STUDY ON THE TREATMENT OF IBVC IMMOVABILITY BY ENDOSCOPY POSTERIOR TRANSVERSE WITH DIATHERMY

Objectives: The main objective of this research work is to evaluate the effectiveness, abnormalities and safeties rate of PTC (posterior transverse cordotomy) in the management of immobility of IBVC (iatrogenic bilateral vocal cord). Methodology: This research work was conducted on twelve female patients with immobility of IBVC after the operation of thyroid who visited Outpatient Department of otolaryngology in Mayo Hospital Lahore. The duration of this research was from January 2014 to December 2017. PTC endoscopy was performed on every patient. These patients had to follow up for one hundred and eighty days & they were assessed for the frequency of decannulation, the condition of voice after surgery and other related abnormalities. Results: Nine patients got flourishing decannulation on third day after the surgery. Two patients were in need of another operation for other vocal cord. The analysis of after surgery voice displayed that 8 patients had the same voice as before surgery and only one patient has bad voice. After surgery, dyspnoea was not available in six patients, it was mild in five patients and it was severe in only one case. No patient found any difficulty in swallowing the food & breathing. This whole method was from eight to nineteen minutes. The average duration of this method was 10.6 minutes. Conclusions: The treatment of immobility of IBVC with the help of electrocautry has the ability to create proper voice after surgery. This method is full of safety and it is not associated with severe complications. Key Words: IBVC, PTC, decannulation, vocal, swallow, endoscopy, surgery, severe, complication
