Abstract
|
|
|
Background and Objectives : Little information about the surgical anatomy and technique for
retropharyngeal node dissection has been published. The purpose of this study was to review our surgical
technique and results of retropharyngeal lymph node dissection.
Materials and Methods : Eleven advanced oropharyngeal and hypopharyngeal squamous cell carcinoma
patients who had been treated with resection of primary tumor and standard neck dissection including
retropharyngeal lymph node dissection from 1994 to 1999 were evaluated retrospectively.
Results : One of 11 patients had positive retropharyngeal lymph node. The surgical technique used for
retropharyngeal lymph node dissection were total laryngopharyngectomy, mandibular splitting or
mandibulectomy approach. There was no specific complication of retropharyngeal lymph node dissection
except one case of Horner’s syndrome.
Conclusion : Retropharyngeal lymph node dissection was a safe procedure, but it required total
laryngopharyngectomy, madibular splitting or mandibulectomy approach. It was possible to remove
retropharyngeal lymph node en-bloc with primary tumor in most cases.
