Postoperative pain and analgesic consumption after endoscopic and microscopic ear procedures.

Objective: Endoscopic ear surgery (EES) is considered a minimally invasive technique. It is hypothesized that patients after endoscopic procedures experience less pain and require fewer painkillers. Our aim was to compare patients' postoperative pain and need for analgesics in patients undergoing microscopic and endoscopic ear surgeries.

Comparison of lymphatic vessel density and expression of VEGF-C and VEGF-D lymphangiogenic factors in Warthin's tumours and oncocytic adenomas.

Objectives: To compare the density of lymphatic vessels and VEGF-C and VEGF-D expression in Warthin's tumours (WTs) and oncocytic adenomas (OCAs).

Methods: Twenty three WTs and 13 OCAs of the parotid gland were analyzed. Lymphatic vessels were detected using the D2-40 antibody.

Recidivous cholesteatoma: DWI MR after canal wall up and canal wall down mastoidectomy.

Objectives: To investigate the correlation between preoperative non-echo planar diffusion-weighted (non-EPI DWI) MR imaging with surgical findings of recidivous middle ear cholesteatoma after canal wall up (CWU) and canal wall down (CWD) mastoidectomy.

Background: The detection of recidive cholesteatoma after CWU and after CWD procedures, when the trepanation cavity is spontaneously closed by soft tissue, is possible by second-look and revision surgery. However, many cases prove to be negative of the disease.

Color Doppler Ultrasound in the pre-histological determination of the biological character of major salivary gland tumors.

Objectives: The aim of the study was to assess the use of color Doppler ultrasound in the pre-histological determination of the biological features of salivary gland tumors.

Material And Methods: Ninety-six patients with major salivary gland tumors of unknown histology were examined and operated on in our clinics. They were pre-operatively examined using ultrasound imaging with color Doppler.
