Tracheal/Laryngeal Infiltration in Thyroid Cancer: a Single-Centre Experience.

Around 1/3 of patients of locally advanced carcinoma thyroid present with tracheal infiltration either alone or along with infiltration of other adjacent structures. Even though trachea is infiltrated, adequate resection is the main modality of treatment in these patients. We retrospectively analysed carcinoma thyroid patients who were operated at our institute, between January 2011 and December 2018, and underwent thyroidectomy with tracheal or laryngeal resection. Seventeen patients underwent tracheal/laryngeal resection with thyroidectomy. The mean age of patients was 57 years. Six and eleven were male and female, respectively, 0.14 (82%) patients had dyspnoea on presentation, 6 had hoarseness of voice, 6 had haemoptysis, and in 2 patients, neck swelling was the only complain. Two patients in our study presented with acute stridor, underwent emergency intubation and subsequently surgery. Two other patients had bulky pedunculated tumour in preoperative bronchoscopy and required tracheostomy for intubation before proceeding with surgery. In 11 patients, sleeve resection followed by end-to-end anastomosis was done, window resection was done in 3 patients, partial laryngectomy in 1, and total laryngectomy in 2 patients. In 10 patients (59%), the site of infiltration was in the lateral tracheal wall, with relatively small posterior primary (mean size 3.7 cm) in the thyroid lobe. Two patients developed postoperative complication, one patient with sleeve resection had secondary haemorrhage, and one patient who underwent window resection with myochondrial thyroid lamina flap reconstruction developed salivary fistula. These patients underwent re exploration with tracheostomy and were subsequently decannulated. Preoperative diagnosis of tracheal infiltration helps in better planning of surgery and counseling the patients of any possible complication. Clinical workup and pre-emptive diagnosis is therefore of paramount importance.
