Surgical Treatment of Retrosternal Goitre

Abstract

This study aims to evaluate surgical approaches to the management of retrosternal goitre. Between 2004 and 2014, 35 patients (eight males; mean age 67.4 ± 10.9 years) with retrosternal goitre (mainly right-sided in 9, left-sided in 14 and bilateral in 12) underwent surgery. A palpable neck mass was found in 11 (31.4%), stridor in 10 (28.6%) and thyrotoxicosis in 4 (11.4%) cases. 4 (11.4%) patients were asymptomatic. Tracheal compression was detected radiologically in 27 (77.2%) patients with deviation in 18 (51.4%). A collar incision was performed in 34 patients, 6 (17.1%) of whom required additional sternotomy, 1 (2.9%) was assisted by an anterior mediastinotomy. 1 (2.9%) had a right lateral thoracotomy. There was no operative mortality. Transient vocal changes occurred in 3 (8.6%) patients, recurrent laryngeal nerve palsy in 3, atrial fibrillation in 2, and wound complications in 2 (5.7%). Hospital stay ranged from 2 to 12 days (5.5 ± 2.0). Multinodular goitre was found in 33 patients, diffuse goitre in 1 and ectopic thyroid in 1. The average vertical length of goitres in the collar incision group was 7.6 cm compared to 10.6 cm in the sternotomy group. The average weight of specimens was 156.3 g in patients with collar incisions and 307.5 g in the sternotomy group. Removal of retrosternal goitre is more commonly performed via a cervical collar incision with mandatory availability of sternotomy. Radiological measurement of craniocaudal length may predict the risk of sternotomy. Surgical outcomes are not affected by surgical approach.
