Background:
The purpose of this study is to determine the incidence and risk factors for bilateral tonsillar cancers treated with transoral robotic surgery (TORS) and to determine the morbidity of the procedure.
Methods:
Patients undergoing TORS for known tonsillar cancer were retrospectively reviewed. Perioperative variables and surgical outcomes were analyzed to determine predictive factors for bilateral disease and morbidity rates.
Results:
Seventy-nine consecutive patients with tonsillar cancers underwent primary TORS radical tonsillectomy. Thirty of these patients also underwent contralateral tonsillectomy. Three patients (10%) were found to have contralateral tonsillar cancers on final pathology. These were not identified on preoperative positron emission tomography (PET)-CT or clinical examination. There were no differences in complications, gastrostomy tube (G-tube) rates, or length of stay (P > .05). Blood loss was 11.5 cc more in the contralateral tonsillectomy group (P = .001).
Conclusion:
All patients undergoing primary TORS for tonsillar cancers should also undergo contralateral tonsillectomy to optimize oncologic outcomes with no increase in morbidity.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
