The Transverse Turbinate Line: A Reliable Landmark for the Maxillary Sinus Natural Ostium.

Objectives: Approximating the maxillary sinus natural ostium's (MSNO) natural position during anterograde surgery is challenging, as only a single visual "landmark," the maxillary line, is routinely offered to guide the identification of the MSNO in three-dimensional space. Despite almost 40 years of endoscopic sinus surgery (ESS) experience in North America, maxillary recirculation and discontinuity between the natural and surgical ostia are commonly encountered during revision ESS. Consequently, we feel an additional visual landmark would assist in localizing the MSNO with or without image guidance.

Does lymphovascular invasion predict survival in oral cancer? A population-based analysis.

Objective: To evaluate lymphovascular invasion as an independent predictor for overall survival in patients with oral cavity squamous cell carcinoma.

Study Design: Retrospective cohort study.

Setting: Multi-center, population-based facilities reporting to the National Cancer Database registry.

Retromolar trigone squamous cell carcinoma: A population-based analysis of survival.

Objectives: To evaluate the difference in overall survival (OS) in patients with retromolar trigone squamous cell carcinoma (RMT SCC) treated with surgery alone versus surgery plus postoperative radiotherapy (PORT) versus surgery plus postoperative chemoradiotherapy (POCRT).

Materials And Methods: Retrospective cohort study of patients from 1,500 US facilities reporting to the National Cancer Database (NCDB) registry. Participants were adult patients treated with surgery as primary treatment modality for RMT SCC (n = 2,877).
