Transoral lateral oropharyngectomy for squamous cell carcinoma of the tonsillar region: I. Technique, complications, and functional results.
OBJECTIVE
To describe the surgical technique for transoral lateral oropharyngectomy (TLO) and its safety, postoperative management, complications, and functional outcomes.


METHODS
A 20-year retrospective case series review. Mean follow-up was 10 years. All but 10 patients were followed up until the fifth postoperative year or death.


METHODS
Academic, tertiary referral center.


METHODS
A total of 191 patients who underwent TLO for selected invasive squamous cell carcinoma of the tonsil and/or tonsillar fossa.


METHODS
Ten patients had received preoperative radiation therapy. Induction chemotherapy was used in 153 patients (80.3%). An associated neck dissection was performed in 148 patients (77.5%). Postoperative radiation therapy was administered to 52 patients (28.7%).


METHODS
Overall survival rate, intraoperative mortality, and perioperative mortality were determined. The need for and length of nasogastric tube feeding and tracheotomy were calculated. The incidence of significant postoperative surgical and medical complications was recorded.


RESULTS
No intraoperative mortality occurred, but 5 patients (2.6%) died in the immediate postoperative period, 3 from medical complications and 2 from unknown causes. In this series, the internal carotid artery was never injured, and no cutaneous-oropharyngeal fistulas were apparent. The incidence of significant surgical complications from the oropharynx was 6.3%. Nasopharyngeal reflux and severe rhinolalia were the most common complications, occurring in 9 patients. Increasing tobacco use was statistically correlated with an increase in postoperative pneumonia from aspiration (P = .05) but no surgical complications. Seven patients (3.7%) had a temporary tracheotomy for a mean of 5 days. One hundred twelve patients (58.6%) had a nasogastric tube inserted for a mean of 6 days. No patients had a permanent gastrostomy or tracheotomy tube. The mean duration of hospitalization was 9 days. The duration of hospitalization was statistically correlated with the need for nasogastric tube placement and its duration (P<.001) or tracheotomy (P<.001).


CONCLUSIONS
From a functional standpoint, the TLO is a safe surgical approach for treating selected carcinoma of the tonsillar fossa. It is a reliable technique that should be considered for treatment of appropriate squamous cell carcinoma of the tonsil.
