Abstract: INTRODUCTION: Goitres that extend beyond the thoracic inlet are defined as retro-sternally extending (RSE) goitres. These RSE goitres are a surgical challenge and their characteristics could be different to the goitres confined to the neck. METHOD: A retrospective case-control study. Patients were selected from the thyroid database maintained in our unit (from November 2002 to February 2016). Patients with RSE goitres (confirmed by imaging) were selected as study group (SG). Control group (CG) patients (with goitres confined to the neck) were systematically selected in a 1:2 ratio. The end points were: (i) incidence of RSE goitres, (ii) clinical presentation, (iii) degree of RSE (iv) thyroid status, (v) post operative complications and (vi) histological pattern. RESULTS: 527 consecutive patients (465 female: 62 male; median age 45 years, range 17 years to 71 years) were studied. For the case control study, there were 51 patients in the study group and 102 patients in the control group. Compression symptoms were not significantly high in the SG (27% vs 17%, p value <0.17). Majority had RSE of both lobes (78%). The median depth of extension into the mediastinum was 41.6mm (range 12mm - 95mm). A majority were euthyroid (SG 78% vs CG 82%). Post operative stridor was significantly high in the SG (7% vs 2%; P value = 0.015). Although a majority was colloid goitres, papillary carcinoma was significantly high in the CG (P value < 0.05). CONCLUSIONS: A majority of RSE goitres did not present with compression symptoms, but had significantly high post-operative stridor (p value <0.05). Incidence of cancer is not high in SG.
