Radical resection and reconstruction in patients with adenoid cystic carcinoma in the minor salivary glands of the palate.

Background: This study evaluated the clinical outcomes of the patients with adenoid cystic carcinoma (ACC) of the minor salivary glands of the palate.

Methods: Forty-four patients with stage I-II disease and 14 patients with stage III-IV disease underwent radical excision and reconstruction with a facial-submental artery island flap (FSAIF) and titanium mesh plus a free anterolateral thigh flap (ALTF) and radiotherapy respectively. Patients with stage III-IV disease subsequently received cobalt Co 60 adjuvant radiotherapy.

Reconstruction of Large Acquired Palatal Defects Using Facial-Submental Artery Island Flap.

Objective: To evaluate the feasibility and clinical effect of facial-submental artery island flap (FSAIF) in the repair of palatal defects, and to provide reference for the clinical application of submental artery island flap.

Methods: Nine patients with palatal defects, the range of nasal palatal perforation defects were 3 cm × 4cm to 3 cm × 6 cm (median 3 cm × 5.4 cm), were repaired by FSAIF, and the sizes of FSAIF were 4 cm × 9cm to 4 cm × 12 cm (median 4 cm × 10.

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.

Comprehensive treatment of massive macroglossia due to venous and lymphatic malformations.

This study evaluated the outcomes of comprehensive treatment for massive macroglossia. Eleven patients with massive macroglossia due to venous malformations (VMs) and lymphatic malformations (LMs) underwent incision excision of two-thirds of the central wedge of the tongue; two of these patients underwent resection of lesions in the lower lip or floor of the mouth during initial treatment. In subsequent treatment, three patients underwent orthognathic surgery or resection of lesions in the lower lip and submental region, and four patients underwent one or two sclerotherapies.

Comparison of the reconstruction of through-and-through cheek defects involving the labial commissure following tumor resection using four types of local and pedicle flaps.

Background: The reconstruction of through-and-through cheek defects involving the labial commissure following cancer ablation is a surgical challenge.

Methods: This study evaluated 35 patients with buccal squamous cell carcinoma (SCC) involving the labial commissure who underwent Abbe-Estlander (A-EF), folded extended supraclavicular fasciocutaneous island (SFIF), folded pectoralis major muscle (PMMF), or folded extended vertical lower trapezius island myocutaneous (TIMF) flap reconstruction of through-and-through cheek defects involving the labial commissure following radical resection.

Results: The A-EF and SFIF groups differed significantly (P < 0.

Relationship between the genetic polymorphisms of vicR and vicK Streptococcus mutans genes and early childhood caries in two-year-old children.

Background: The VicRK two-component signalling system regulates virulence and cariogenicity in Streptococcus mutans (S. mutans). The purpose of this study was to explore the genetic polymorphisms of the vicR and vicK genes, which are associated with dental caries in children with S.

Cancer-associated fibroblasts confer cisplatin resistance of tongue cancer via autophagy activation.

Cancer-associated fibroblasts (CAFs) play important roles in carcinogenesis and progression of tongue squamous cell carcinoma (TSCC). However, effect of CAFs on chemotherapy resistance of TSCC remains largely obscure. Here, we cultured the matched primary CAFs and normal fibroblasts (NFs) pairs and detected their roles in cisplatin sensitivity of TSCC, as well as autophagy-related protein LC3 and Beclin1 expressions.

The Effect of Reading Aloud Exercises for Complete Denture Patients during the Functional Rehabilitation Period.

Purpose: The focus of this study was to evaluate the effect of reading aloud on masticatory performance and patient satisfaction of patients rehabilitated with conventional complete dentures for the first time.

Materials And Methods: Sixty-two edentulous patients who received conventional complete denture treatment for the first time were randomly divided into two equal groups. After insertion of the dentures, patients in group I were asked to read a news report three times per day for 4 weeks, while those in group II did not read.

Effect of heating palladium-silver alloys on ceramic bond strength.

Statement Of Problem: The effects of different heat treatments on the internal oxidation and metal-ceramic bond in Pd-Ag alloys with different trace elements require further documentation.

Purpose: The purpose of this in vitro study was to determine whether heat treatment affects the metal-ceramic bond strength of 2 Pd-Ag alloys containing different trace elements.

Material And Methods: Thirteen cast specimens (25×3×0.

Effect of titanium preoxidation on wrought pure titanium to ceramic bond strength.

Statement Of Problem: The creation of high bond strength between machined computer-manufactured pure titanium and porcelain remains a problem. However, machined titanium does not form the thick titanium oxide film found in cast titanium.

Purpose: The purpose of this study was to investigate the effects of different preoxidation treatments on the bond strength of a machined pure titanium ceramic system.

[Effect of different heat treatment on the bonding strength of porcelain and Co-Cr alloy].

Purpose: To investigate and compare the effect of different heat treatment on the metal- ceramic bonding strength and the interfacial microstructure of the Co-Cr alloy.

Methods: Thirty specimens were made according to ISO 9693,and then divided into 3 groups (n=10) through the measurements .Group A(degassed 60s):degassed and then maintained 60s in 980 degrees centigrade Group B(degassed 60s and preoxidation 60s): degassed and maintained 60s in 980 degrees centigrade, then were maintained continuously for 60s in 980 degrees centigrade after re-gassed,Group C(degassed 120s): degassed and maintained 120s in 980 degrees centigrade.
