Electrocautery, Harmonic, and Thunderbeat Instruments in Parotid Surgery: A Retrospective Comparative Study.

The aim of this retrospective study has been to compare the surgical outcomes of patients undergoing superficial parotidectomy with three different instruments: bipolar electrocautery, ultrasound, and mixed energy instruments. The clinical records of 102 patients who had undergone superficial parotidectomy for benign tumors between January 2016 and April 2022 were considered. Based on the tool used during the surgery, the patients were divided into three study groups: classic electrocautery hemostasis group (CH group), ultrasonic instrument group (HA group), and combined energy instrument group (TB group).

Prevalence of Persistent Olfactory Disorders in Patients With COVID-19: A Psychophysical Case-Control Study With 1-Year Follow-up.

The purpose of this multicenter case-control study was to evaluate a group of patients at least 1 year after coronavirus disease 2019 (COVID-19) with Sniffin' Sticks tests and to compare the results with a control population to quantify the potential bias introduced by the underlying prevalence of olfactory dysfunction (OD) in the general population. The study included 170 cases and 170 controls. In the COVID-19 group, 26.

Neck dissection with harmonic instruments and electrocautery: a prospective comparative study.

Background: Harmonic instruments are becoming popular in head and neck surgeries. In this prospective, randomized study, the efficacy of the harmonic instruments and electrosurgical technique is compared.

Materials And Methods: A total of 48 patients undergoing unilateral neck dissection were divided into two groups.

New protocol for in-house management of computer assisted orthognathic surgery.

The aim of this study was to evaluate retrospectively the accuracy of a protocol for completely in-house, computer-assisted, orthognathic surgery, generating resin printed intermediate surgical guides. A retrospective, observational study was made on a cohort of 15 patients treated consecutively from September 2017 to May 2019, who underwent bimaxillary orthognathic surgery planned with the same 3-dimensional program and whose surgical intermediate splints were obtained with the same all-in-house protocol. Virtual planned surgical movements were compared with the real surgical outcome.

Objective evaluation of anosmia and ageusia in COVID-19 patients: Single-center experience on 72 cases.

Background: The first European case series are detecting a very high frequency of chemosensitive disorders in COVID-19 patients, ranging between 19.4% and 88%.

Methods: Olfactory and gustatory function was objectively tested in 72 COVID-19 patients treated at University Hospital of Sassari.
