The Use of Water Sac Dilation in Resecting Parapharyngeal Space Benign Tumor via Transoral Approach.

Objectives: To evaluate the effectiveness of employing the water sac dilation (WSD) method during endoscopy-assisted transoral resection of parapharyngeal space benign tumor (PSBT).

Methods: Between February 2017 and January 2022, a total of 32 patients diagnosed with PSBT were included in this prospective study and were randomly allocated into two groups: the WSD group and the control group. Tumors of the WSD group patients were all dissected using the WSD method.

A CT-based integrated model for preoperative prediction of occult lymph node metastasis in early tongue cancer.

Background: Occult lymph node metastasis (OLNM) is an essential prognostic factor for early-stage tongue cancer (cT1-2N0M0) and a determinant of treatment decisions. Therefore, accurate prediction of OLNM can significantly impact the clinical management and outcomes of patients with tongue cancer. The aim of this study was to develop and validate a multiomics-based model to predict OLNM in patients with early-stage tongue cancer.

Endoscope-Assisted Resection of Benign Parotid Tumors via Concealed Post-Auricular Sulcus Incision.

Objectives: To investigate the feasibility, safety, and effectiveness of endoscopic-assisted resection of benign parotid tumors via concealed post-auricular sulcus incision.

Methods: Between October 2019 and March 2021, eligible patients with diagnosed benign parotid tumors were prospectively included and randomly assigned to two groups: the endoscope-assisted post-auricular sulcus incision group (endoscope group) and the conventional Blair "S" incision group (conventional group).

Results: A total of 45 patients were finally included, including 24 subjects in the endoscope group and 21 subjects in the conventional group.

Application of haemoglobin absorption spectral imaging in laryngeal papilloma surgery.

Objective: This study compares the detection rates of haemoglobin absorption spectral imaging and white light imaging in laryngeal papilloma surgery.

Methods: Seventeen patients with laryngeal papilloma who underwent surgery in our department from September 2019 to September 2021 were selected. All patients underwent carbon dioxide laser surgery under a microscope.

Risk Factors to Predict Neurologic Complications After Endovascular Treatment of Unruptured Paraclinoid Aneurysms.

Objective: Unruptured paraclinoid aneurysms are often asymptomatic, and endovascular coiling is the main treatment. However, endovascular treatment of these lesions still leads to neurologic complications. We aimed to identify predictors of neurologic complications in these lesions.

Outcome of children with edge-everted traumatic tympanic membrane perforations following spontaneous healing versus fibroblast growth factor-containing gelfoam patching with or without edge repair.

Objectives: To retrospectively analyze the outcome of children with edge-everted tympanic membrane (TM) perforations following spontaneous healing and fibroblast growth factor-containing gelfoam patching with or without repair of the edge flaps.

Methods: Medical records of children with TM perforations who underwent spontaneous healing (n = 69) or received fibroblast growth factor (FGF)-containing gelfoam patching treatment (n = 67) were retrieved from the Records Department of the Wenzhou Medical College-Affiliated Yiwu Hospital in China. The demographic data and outcome measures were analyzed and compared between these two groups of patients.

Impact of different contraceptive methods on quality of life in rural women of the Jiangsu province in China.

Background: The combined oral contraceptives (COCs) and intrauterine devices (IUDs) are the most common contraceptive methods used by women. Women's choices of contraceptive method are largely affected by the safety and efficacy of contraceptive methods as well as by change in women's quality of life. However, there are still scanty data focusing on the impact of COC or IUD on quality of life in women, especially in China.

[Effects of different land use types on soil nutrients in karst region of Northwest Guangxi].

Selecting the main land use types (shrub land, secondary forest land, orchard, pasture land, and upland) at the peak-cluster depression in karst region of Northwest Guangxi as test objects, this paper studied the effects of different land use types on soil nutrients. The results showed that, the contents of soil organic matter (SOM), total N, and available N were 86%-155%, 62% -119%, and 66%-215% higher in shrub land and secondary forest land than in orchard, pasture land, and upland, respectively, i. e.
