Abstract
Background
The presence of a plane between the lingual tonsils and the underlying soft tissue has not been confirmed. The objective of this study is to ascertain the presence and the characteristics about this plane for surgical use.
Methods
Five cadaver heads were obtained for dissection of the lingual tonsils. Six permanent sections of previous tongue base biopsies were reviewed. Robot assisted lingual tonsillectomy was performed using the dissection technique from the cadaver dissection.
Results
In each of the 5 cadavers, an avascular plane was revealed deep to the lingual tonsils. Microscopic review of the tongue base biopsies revealed a clear demarcation between the lingual tonsils and the underlying minor salivary glands and muscle tissue. This area was relatively avascular. Using the technique described above, a lingual tonsillectomy using TORS was performed with similar findings from the cadaver dissections.
Conclusions
A surgical plane for lingual tonsillectomy exists and may prove to have a role with lingual tonsillectomy with TORS.
