Rationale for elective modified neck dissection.

摘要: A retrospective study was conducted to give surgeons direction in deciding which type of modified neck dissection is proper elective treatment for the patient with a clinically negative neck. The medical records 428 previously untreated patients (seen between January 1, 1970, and December 31, 1979) whose necks (i.e., NO) were electively dissected who had primary squamous carcinoma oral cavity, oropharynx, larynx, or hypopharynx included. three major types dissections studied supraomohyoid, anterior, functional. Sixteen percent (70 428) multiple positive nodes 6% (28 evidence extracapsular invasion. unilateral supraomohyoid most often used primaries cavity. Bilateral anterior common cancers larynx hypopharynx, functional equally distributed among sites. None pathologically submental submaxillary triangles. Advanced T-stage generally associated greater incidence subclinically nodes. Thirty received postoperative radiotherapy. total number removed, without invasion, anatomic location correlated dissection, stage site cancer, use radiotherapy, regional (neck) failure, survival.(ABSTRACT TRUNCATED AT 250 WORDS)
