Quality of life and survival rate after primary surgical treatment of oral squamous cell carcinoma: A retrospective study with 18 years of follow-up.

The aim of this study is to evaluate the long-term survival rates and assess the long-term quality of life (QoL) of patients treated for oral squamous cell carcinoma (OSCC). Patients, who underwent primary surgical tumor resection for OSCC at a single hospital center in Germany between 1998 and 2016, were eligible for inclusion in this analysis of survival rates and QoL parameters. The University of Washington-QoL version 4 (UW-QoL v4) questionnaire was administered to the patients in the years 2015 and 2016.

Use of ultrasonic scalpel and monopolar electrocautery for skin incisions in neck dissection: a prospective randomized trial.

Purpose: Ultrasonic scalpel (UC) and monopolar electrocautery (ME) are standard equipment for soft tissue surgery. The aim of the present study was to compare intraoperative and postoperative patterns of patients using either UC or ME for skin incisions in neck dissection.

Material And Methods: In a prospective randomized study of 30 patients, the thermal effects of UC (n = 15) and ME (n = 15) were examined using real-time infrared thermographic imaging.
