CONCLUSION: This study showed that elective neck dissection (ND) resulted in reduced regional recurrences in a selected group of surgically treated patients with pT1-2 carcinomas but did not show any benefit for disease-specific survival (DSS). Furthermore, the importance of pN classification was also verified for this patient group. OBJECTIVES: The aim of this study was to determine whether the use of elective ND in patients with early head and neck carcinomas and cN0 neck that have undergone a transoral removal of the primary tumor can reduce the incidence of regional recurrence and improve survival. METHODS: Between 1980 and 2010, 224 patients that underwent transoral resection of a pT1-2 carcinoma and had a cN0 neck were included in the study; 101 patients received an elective ND and 123 did not. RESULTS: The group that underwent elective ND showed a tendency toward better regional control (RC) (96.0% vs 90.3%, p = 0.07) but similar DSS (85.7% vs 85.4%, p = 0.984). Cases with pN0 classification had a better overall survival (74.6% vs 46.9%, p = 0.07), DSS (88.4% vs 53.6%, p = 0.44), and RC (98.6% vs 62.5%, p < 0.001) compared with pN+ patients.
