Thyroglossal duct cysts (TDC) are the most common congenital cervical
abnormality. On the other hand, lingual TDC are rare, comprising
between 0.6% -3% of all TDC. We present the case of a patient with
recurrence of the
TDC, at the base of the tongue.
Five-year-old patient with TDC was admitted on a scheduled basis to excise it.
Exeresis of the cyst was performed using the Sistrunk technique.
Postoperative elapsed without incidents, being discharge on the
day. Three years after surgery, the patient returned for dysphagia
and the appearance of a tumour on the base of the tongue (A).
Cervical ultrasound was performed, showing a suprahyoid cystic structure, adjacent
to the posterior third of the tongue, dependent on the blind foramen,
compatible with lingual TCD (B). The patient underwent an intraoral
complete removal of the cyst. Pathological anatomy confirmed the
suspicion of TCD.
TCD form anywhere from the blind foramen of the tongue to the base of the neck.
Sixty one percent of the cysts are located between the thyroid
gland and the hyoid bone and 1-2% are intralingua. Cases of transoral
using the Sistrunk technique are reported. We performed the first
one, since the patient had already undergone cervical surgery.
The exploration of the
oral cavity in these patients is essential, since, as we have seen
and learned in this case, there may be a recurrence or extension
of the cyst to the
blind foramen of the tongue.
