Sentinel Node in Oral Cancer: The Nuclear Medicine Aspects. A Survey from the Sentinel European Node Trial.

Purpose: Nuclear imaging plays a crucial role in lymphatic mapping of oral cancer. This evaluation represents a subanalysis of the original multicenter SENT trial data set, involving 434 patients with T1-T2, N0, and M0 oral squamous cell carcinoma. The impact of acquisition techniques, tracer injection timing relative to surgery, and causes of false-negative rate were assessed.

Sentinel European Node Trial (SENT): 3-year results of sentinel node biopsy in oral cancer.

Purpose: Optimum management of the N0 neck is unresolved in oral cancer. Sentinel node biopsy (SNB) can reliably detect microscopic lymph node metastasis. The object of this study was to establish whether the technique was both reliable in staging the N0 neck and a safe oncological procedure in patients with early-stage oral squamous cell carcinoma.

Implications of a positive sentinel node in oral squamous cell carcinoma.

Background: The role of sentinel node biopsy in head and neck cancer is currently being explored. Patients with positive sentinel nodes were investigated to establish if additional metastases were present in the neck, their distribution, and their impact on outcome.

Methods: In all, 109 patients (n = 109) from 15 European centers, with cT1/2,N0 tumors, and a positive sentinel lymph node were identified.

Mandibular condyle fractures: determinants of treatment and outcome.

Purpose: The objective of this study was to analyze the principal variables that determine the choice of the method of treatment and the outcome in condylar fractures.

Materials And Methods: We conducted a retrospective analysis of 104 mandibular condyle fractures to analyze and determine the relation between the principal clinical variables and the postoperative results. All patients underwent a clinic-radiologic investigation focusing on fracture remodeling, evolution, dental occlusion, and symmetry of the mandible.

Porous polyethylene implants in orbital floor reconstruction.

The purpose of this article is to present the authors' experience with the use of porous polyethylene ultrathin sheets for orbital floor reconstruction. Thirty-two patients with orbital floor fractures were treated with porous polyethylene ultrathin sheets. Sixteen cases corresponded to orbitozygomatic fractures, 11 cases corresponded to pure orbital floor fractures, and five corresponded to panfacial fractures.
