Retrospective analysis of a case series.
Referral center, private or institutional practice, hospitalized care.
To analyze the level (site) of ipsilateral neck recurrences after supraomohyoid (SOH) dissection in patients with lip, oral, and oropharyngeal cancer treated in a single institution.
Supraomohyoid neck dissection.
Patients and Methods
From 1979 to 1997, 154 patients with oral and oropharyngeal carcinoma and no palpable lymph nodes at the neck underwent ipsilateral elective SOH dissection.
Tumor sites were the lip, 5 cases (3.3%); oral cavity, 128 cases (83.1%); and oropharynx, 21 cases (13.6%). Tumor stages were T1, 13 cases (8.4%); T2, 77 cases (50.0%); T3, 40 cases (27.0%); and T4, 22 cases (14.3%). There were 7 cases (4.5%) of ipsilateral neck recurrences. Three were beyond the limits of the SOH dissection, and 4 were inside these limits. There was no association of neck recurrences with the pathological status of the lymph nodes. Six of the 7 recurrences were in patients who underwent postoperative radiotherapy.
The incidence of neck recurrence after selective neck dissection was 4.5%, and it occurred either inside (57.1%) or beyond (42.9%) the limits of the selective neck dissection.
