Classification and Treatment of Complications Related to Titanium and Biodegradable Miniplates Using the Lip-Split Transmandibular Approach for Oral and Oropharyngeal Oncological Surgery.

Background: There is a lack of classified definitions and corresponding treatment principles for complications related to titanium miniplate (TMP) and biodegradable miniplate (BMP).

Aims: This study proposes a classification system for complications related to TMP and BMP osteosynthesis and evaluates the effectiveness of the classification system in the treatment of the complications.

Methods: One hundred forty-two patients with advanced-stage oral cavity and oropharynx squamous cell carcinoma (SCC) underwent oncological surgery via lip-split transmandibular (LTM) approach including midline, paramedian, stair-step, and triangle.

Detecting recurrent disease and surgical outcomes in patients with locally advanced tongue cancer after multimodal treatment using ¹⁸F-FDG-PET/CT.

The purpose of this study was to evaluate the utility of ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (FPCT) parameters for detecting recurrent disease and the outcomes of salvage surgery in patients with locally advanced oral tongue squamous cell carcinoma (TSCC) after multimodal treatment. In total, 69 patients with locally advanced TSCC were treated with multimodal therapy. All patients underwent whole-body FPCT scans 4-10 months after the initial surgery.

Various Types of Facial-Angular Artery-Based Flaps for Reconstructing Oral and Maxillofacial Defects Following Cancer Ablation.

Background: The flap based on the facial-angular vessels (FAVs) has several names and cannot capture the hemodynamics.

Aims: This study was performed to assess the reliability of various types of flaps based on the FAVs for reconstructing oral and maxillofacial defects following cancer ablation.

Patients And Methods: Forty-three oral and maxillofacial defects were reconstructed with facial-angular artery island flaps (FAAIF, n =14), including V-Y advancement-type and rotation-type flaps based on FAVs and reverse-flow FAAIFs (R-FAAIF, n =29), including ipsilateral, contralateral rotation, full-thickness, and folded types, based on distal FAVs following cancer ablation.

Maxillectomy and Flap Reconstruction of Maxillary Defects After Cancer Ablation Through the Lip-Split Parasymphyseal Mandibulotomy Approach in Patients With Advanced-Stage Maxillary Malignant Tumors.

Background: The conventional approach for maxillectomy has some common and serious complications.

Aims: The present study evaluated the outcomes of maxillectomy and flap reconstruction after cancer ablation using the lip-split parasymphyseal mandibulotomy (LPM) approach.

Methods: Twenty-eight patients with malignant tumors, including squamous cell carcinoma, adenoid cystic carcinoma, and mucoepidermoid carcinoma, underwent maxillectomy through the LPM approach.

Facial-submental island flap for reconstruction of hemitongue defects in young, middle-aged and elderly patients with early and middle stage oral tongue squamous cell carcinoma.

Background: This study evaluated the outcomes of facial-submental artery island flap (FSAIF) for reconstruction of the hemitongue following cancer ablation in patients with early and middle-stage oral tongue squamous cell carcinoma (OTSCC).

Methods: In total, 122 patients with early and middle-stage OTSCC were divided into young, middle-aged, and elderly groups. The Adult Comorbidity Evaluation-27 (ACE-27) index was used to determine the presence of comorbidities.

Outcomes of patients with mucoepidermoid carcinoma of minor salivary gland in palate undergoing radical resection followed by submental flap reconstruction.

Objective: To investigate the outcomes of patients with mucoepidermoid carcinoma of the palate undergoing pedicled facial-submental artery island flap (FSIF) reconstruction following resection.

Patients And Methods: 41 patients with early stage disease and 9 patients with advanced-stage disease underwent radical excision and neck dissection. 37 IIb, 4 class IIa and 9 IIIb maxillary defects were reconstructed with FSIF, folded FSIF or folded FSIF with titanium mesh respectively.

Bilateral, buccinator myomucosal advancement flaps to reconstruct central upper labial myomucosal defects after ablation of early-stage cancer in minor salivary glands.

Background: Reconstruction of upper labial myomucosal defects is surgically challenging.

Aims: We evaluated whether central defects could be repaired using bilateral, buccinator myomucosal advancement flaps (b-BMAFs).

Methods: We evaluated five patients with early-stage, minor salivary gland mucoepidermoid carcinomas (low-grade [n = 2], intermediate-grade [n = 2], and high-grade [n = 1]) who underwent central, upper labial myomucosal reconstruction using b-BMAFs after cancer ablation.

Endoscope-assisted Surgery in the Treatment of Dentigerous Cyst Involving the Maxillary Sinus - Report of Two Cases.

Endoscopic techniques have been applied to oral and maxillofacial surgeries. Previous studies have proved their practicability in the treatment of osteomyelitis of the mandible and displaced residual roots in the maxillary sinus. In this report, two patients with dentigerous cysts in the maxillary sinus underwent endoscope-assisted curettage.

Computer-assisted resection and reconstruction of bilateral osteoradionecrosis of the mandible using 2 separate flaps prepared from a single fibula.

Objectives: Osteoradionecrosis of the mandible is a late radiation-induced complication, which is a major concern in survivors of head and neck cancer.

Study Design: In this study, we present a case of a patient with nasopharyngeal carcinoma who developed extensive bilateral osteoradionecrosis of the ascending ramus of the mandible. After preoperative virtual surgical planning, the obtained data were used to fabricate patient-specific cutting templates.

Colistin resistance gene mcr-1 in gut flora of children.

The aim of this study was to determine the prevalence and transmission mechanism(s) of mcr-1 in the gut flora of children. Faecal samples (n = 173) were obtained from non-diarrhoea patients at the Children's Hospital of Zhejiang University (Hangzhou, China). PCR-based analysis indicated that 17 isolates from 9.

Occurrence of Plasmid- and Chromosome-Carried in Waterborne Enterobacteriaceae in China.

The aim of this study was to investigate the prevalence of the polymyxin resistance gene in from environmental water sources in Hangzhou, China. Colistin-resistant bacteria were isolated from environmental water samples using an enrichment broth culture method, were screened for , and then were analyzed for the location and transferability of Isolates positive for were further examined to determine their susceptibility profiles and were screened for the presence of additional resistance genes. Twenty-three -positive isolates (16 , two , two , two , and one ) were isolated from 7/9 sampling locations; of those, eight -positive isolates also contained β-lactamase-resistance genes, eight contained , and 10 contained No -positive isolates were identified.
