title: Airway Management in Patients with Tracheal Compression Undergoing Thyroidectomy: A Retrospective Analysis.
abstract: BACKGROUND
  Airway management in large and retrosternal goiters with tracheal compression is often fraught with challenges and is a source of apprehension among anesthesiologists globally.
  
  
  OBJECTIVE
  In this study we attempt to delineate the preferred techniques of airway management of such cases in our institution and also to assess whether airway management was unnecessarily complicated.
  
  
  METHODS
  Retrospective analysis.
  
  
  METHODS
  A retrospective review was conducted of thyroidectomies performed in our institution over a three year period from January 2013. Clinical, radiological, pathological, anesthetic and surgical data were obtained from hospital case records.
  
  
  METHODS
  Qualitative data is represented as frequencies and percentages and quantitative data as mean and standard deviation.
  
  
  RESULTS
  Of 1861 thyroidectomies tracheal compression were present in 50 patients with minimum tracheal diameter ranging from 4-12mm (mean 7.84); with majority(95%) having a benign pathology. Critical tracheal compression (≤5 mm) was observed in four patients. Conventional intravenous induction and intubation under muscle relaxant was performed in majority (64%) of these patients. The rest of the cases (n=18) were intubated while preserving spontaneous ventilation after induction. Primary technique of airway management was reported successful in all cases with no instances of difficult ventilation or intubation. Postoperative morbidity in few cases resulted from hematoma (n=1), recurrent laryngeal nerve palsy (n=1), tracheomalacia (n=1) and pulmonary complications (n=2).
  
  
  CONCLUSIONS
  Airway management in patients with tracheal compression due to benign goiter is quite straightforward and can be managed in the conventional manner with little or no complications.
