ABSTRACT

OBJECTIVE: Temporomandibular joint osteoarthritis (TMJ-OA) is common in clinic. The purpose of this study was to evaluate the efficacy of disc release, fixation and chitosan injection in the treatment of TMJ-OA. METHODS: From March 2021 to March 2022, 32 patients who underwent the unilateral reduction and fixation of temporomandibular joint disc release were retrospectively studied. All patients were diagnosed with TMJ-OA and were treated with chitosan injection. This group of patients was analyzed by the visual analog scale (VAS) for pain and improvement of maximum comfortable mouth opening before treatment and 6 months after treatment. A paired t-test was used to evaluate the treatment effect, and p < 0.05 indicated that the difference was statistically significant. RESULTS: All 32 patients were successfully treated by surgery and chitosan injection in the second week after operation. The duration of disease in this group ranged from 1 to 10 months, with an average of 5.7 months. After 6 months of follow up, 30 patients were satisfied with the treatment and two were unsatisfied. The difference in the treatment effect was found to be statistically significant (p < 0.05). CONCLUSIONS: Temporomandibular joint disc release and fixation combined with chitosan injection is effective in the treatment of TMJ-OA.

ABSTRACT

PURPOSE: The purpose of this article is to study the effect of autologous platelet-rich plasma (PRP) injected into the upper cavity of the temporomandibular joint (TMJ) on the treatment of TMJ osteoarthritis. PATIENTS AND METHODS: We retrospectively analyzed the data of 27 patients with TMJ osteoarthritis treated at the China Medical University Hospital of Stomatology from September 2018 to September 2019. Maximal interincisal opening, pain intensity, and TMJ sounds were recorded and compared before treatment and at the 3rd and 6th months after the treatment. SPSS 24.0 software was used to analyze the data of each group, and the imaging changes in the condylar bone were compared before and 6 months after the treatment. The P-value was set at .05. RESULTS: Better results were observed in the group treated with PRP on maximal interincisal opening and pain intensity than in the group receiving chitosan treatment. Regarding TMJ sounds, relief was observed in both groups, with no significant difference. CONCLUSIONS: The effect of PRP on the improvement of the maximal interincisal opening and pain intensity of patients with TMJ osteoarthritis is better than that of chitosan. However, it should be noted that the incidence of complications associated with the injection of PRP may be higher than that with injection of chitosan.

ABSTRACT

PURPOSE: To evaluate the clinical value of sialendoscopy in the treatment of Stensen's duct injury. PATIENTS AND METHODS: A total of 5 patients with Stensen's duct injuries who had been treated from December 2017 to April 2019 were included in the present study. The operations were performed with the help of a sialendoscope. All patients were followed for 6 months. RESULTS: The distal end of the ductal system was found precisely with the use of the sialendoscope, and the proximal end was identified by the location of the distal end. The end-to-end anastomosis was performed successfully. None of the patients complained of salivary gland fistula at the 6-month follow-up examination. CONCLUSIONS: The stumps of the ductal system could be precisely and effectively located with the help of a sialendoscope.

ABSTRACT

OBJECTIVES: This study sought to compare surgical outcomes after the removal of submandibular gland (SMG) stones via 2 different surgical methods. MATERIALS AND METHODS: From June 2015 to July 2016, a total of 40 patients with SMG stones were selected from the Department of Oral and Maxillofacial Surgery, School of Stomatology, China Medical University (Shenyang, China), and were randomly assigned to 2 groups. Twenty patients underwent sialendoscopy-assisted stone removal via extraoral incision with preservation of the SMG, and 20 patients underwent traditional SMG resection. The outcomes of the 2 surgical procedures were assessed. RESULTS: The operation time and hospital stay were shorter in the SMG preservation group than the SMG resection group. There were no significant differences in stone size or location between the groups. The mean visual analog scale (VAS) score was lower in the SMG preservation group than the SMG resection group. All patients in the SMG resection group exhibited varying degrees of scarring and concave deformity on the face and neck, whereas all patients in the SMG preservation group retained intact facial morphology. CONCLUSIONS: Sialendoscopy-assisted stone removal with preservation of the SMG exhibited many advantages relative to traditional SMG resection.

ABSTRACT

PURPOSE: The aim of the present study was to evaluate the therapeutic efficiency of sialendoscopy-assisted operations in the treatment of submandibular gland stones. MATERIALS AND METHODS: The data from 8 patients with sialolithiasis who underwent sialendoscopy from August 2015 to January 2016 at the Department of Oral and Maxillofacial Surgery, School of Stomatology, China Medical University (Shenyang, China) were retrospectively reviewed. All the patients had undergone preoperative technetium-99m pertechnetate salivary gland scintigraphy. The results revealed that the salivary glands exhibited normal or slightly reduced uptake and excretion dysfunction. Computed tomography examinations revealed stones located in the intraductal area near the glands or in the branches that could not be removed owing to their deep locations within the mouth. Therefore, an endoscope was inserted, the stones were located intraductally using sialendoscopy, and a transcervical incision was made to remove the stones and preserve the submandibular gland. RESULTS: The stones were completely removed, and the submandibular gland was preserved in all cases. The patients recovered well postoperatively, and no complications developed. CONCLUSIONS: Our results suggest that sialendoscopy-assisted sialolithectomy is an effective and safe surgical technique for the removal of proximal and intraglandular submandibular gland stones. The patients' quality of life had obviously improved postoperatively.

ABSTRACT

PURPOSE: The aim of this study was to describe the effect of vancomycin-impregnated calcium sulfate in the treatment of osteomyelitis of the jaw. MATERIALS AND METHODS: Twelve patients who were diagnosed with osteomyelitis of the jaw underwent treatment with vancomycin-impregnated calcium sulfate since July 2014 at the Department of Oral and Maxillofacial Surgery, School of Stomatology, China Medical University (Shenyang, China). All patients underwent debridement of nonviable bone and implantation of vancomycin-impregnated calcium sulfate. The wounds were covered with an acellular dermal matrix and sutured. RESULTS: Ten patients had satisfactory wound healing. However, 2 cases of maxillary central osteomyelitis had delayed wound healing. The wounds healed after the surgical site was resutured under local anesthesia. At 3 months, the panoramic radiograph showed that most implants had been reabsorbed and replaced by new bone formation. All patients in this study had no recurrence of infection at 6 to 18 months (mean, 10.8 months) of follow-up. CONCLUSIONS: The use of vancomycin-impregnated calcium sulfate in the surgical debridement site for chronic osteomyelitis of the jaw has shown encouraging results. In addition, calcium sulfate can promote the formation of new bone to a certain extent.

ABSTRACT

Osteopetrosis represents a heterogeneous group of rare, hereditary bone disorders with variable clinical features, and an increase in bone density. Osteomyelitis of the jaws is a significant complication of osteopetrosis. In this article, a reported patient with osteopetrosis complicated by osteomyelitis of the mandible was examined. The patient was treated with intravenous antibiotic therapy, debridement of necrotic bone and hyperbaric oxygen therapy; in addition, the authors attempted to implant the calcium sulfate and vancomycin to reconstruct the bone defect. The patient demonstrated satisfactory healing, and no recurrence of osteomyelitis was observed during the 6-month follow-up period. The treatment of osteopetrosis complicated by osteomyelitis of the mandible is difficult. The treatment of osteopetrosis complicated by osteomyelitis is controversial. The authors recommend the following sequential treatment of osteopetrosis complicated by osteomyelitis of the mandible: systemic antibiotic therapy and hyperbaric oxygen therapy before and after surgery; debridement of the necrotic bone; sufficient periosteal coverage and adequate soft tissue to cover the wound; implantation with calcium sulfate and vancomycin to reconstruct the bone defect as much as possible, which may be helpful in treating the disease.
