[The therapeutic role and effectiveness of selective neck dissection in the management of N0 neck].
OBJECTIVE
To assess the therapeutic role and the effectiveness of the selective neck dissection in the management of the clinically node negative neck in the head and neck squamous cell carcinomas.


METHODS
The charts of 177 patients with squamous cell carcinoma, who underwent neck dissection between January 2000 and January 2007, were reviewed retrospectively. Seventy neck dissections in 58 patients (51 males, 7 females; mean age 63 years; range 21 to 85 years) in whom the primary site of the lesion was the larynx, oral cavity, oropharynx and hypopharynx, and who were considered to have N0 neck and to comply with the study criteria were included in the study. Details were collected on tumor site and stage, type of surgery, pathologic N stage, number and size of pathologic nodes, extracapsular spread of nodes, postoperative radiotherapy, local recurrence, follow up time and survival status in all patients.


RESULTS
It was found out that selective neck dissection operations were performed on 99 of 102 N0 patients. The follow up time was approximately 23 months in 58 patients who were found to comply with the inclusion criteria. The most frequent site for primary tumor was larynx and most patients were at T2 stage. Nine patients had pathologically positive lymph node with occult metastasis rate of 13%. The overall recurrence rate was 19%. Postoperative radiotherapy was used as adjuvant therapy in 15 patients. Regional control rate was lower in patients with pathologically positive lymph nodes. However, it was not statistically significant.


CONCLUSIONS
Selective neck dissection is an effective and safe method for controlling and staging of the patients with clinically N0 neck.
