Background
The thyroid disease can appear in 0.16–3.3% of cases as mediastinal goiter. The treatment is difficult and requires a mediastinal
approach.
Materials and methods
We have analyzed our experience from September 1995 to September 2007 among 2,439 thyroidectomies conducted for thyroid disease;
16 cases required a sternotomy, in seven patients conducted as hemiclamshell approach (median sternotomy associated to a fourth
intercostals space incision). Preoperative evaluation included otorhinolaryngology evaluation and computed tomography. All
the cases were followed up to 12 months.
Results
For seven cases treated trough hemiclamshell, the mean age was 57.8 years; hospital stay is 5.2 days. All the patients were
discharged after respiratory evaluation; two patients required a pneumological admittance to physio-kinesi-respiratory. There
were no cases of hemorrhage, nerve injury, permanent hypocalcemia, and chylothorax. There was no mortality at 30 days.
Conclusions
The hemiclamshell is a safe procedure to treat mediastinal goiter and permit a good exposure of subclavian vessels and mediastinal
nodes.
