1.5 cm anterior incision A 12 mm trocar is placed. Gas insufflation is used to
help developing the space. The trocar is then removed and the rest of the
procedure is performed with the space maintained using external retractors.
A 5mm endoscope is placed through the incision Laparoscopic and conventional instruments are used
for the dissection. MiccoliMiccoli et al et al

ConclusionsConclusions Mini-thyroidectomy is feasible and Mini-thyroidectomy is feasible and
safesafe It has excellent cosmetic resultsIt has excellent cosmetic results It can be applied to all patients It can be applied to all patients
regardless of thyroid pathology or regardless of thyroid pathology or sizesize
ConclusionsConclusions Mini-thyroidectomy (along with Mini-thyroidectomy (along with
video assisted thyroidectomy) video assisted thyroidectomy) compared to totally endoscopic compared to totally endoscopic thyroid surgery, have shorter thyroid surgery, have shorter operative times, shorter hospital operative times, shorter hospital stays, comparable cosmetic results stays, comparable cosmetic results without complications related to without complications related to neck insufflationneck insufflation
ConclusionsConclusions The greatest advantage to mini-The greatest advantage to mini-
thyroidectomy is that it requires no thyroidectomy is that it requires no additional technical expertise, and additional technical expertise, and is therefore easier to teach and is therefore easier to teach and reproducereproduce
