RESUMO
OBJECTIVES: Thyroglossal duct cysts (TGDCs) are a common congenital mass in the cervical region. As the traditional surgical approach for TGDC removal, the Sistrunk procedure, often leaves a visible neck scar, the demand for improved cosmetic outcomes has increased. Emerging endoscopy-assisted approaches offer promise for addressing cosmetic concerns. We conducted a scoping review to evaluate the feasibility and safety of endoscopy-assisted TGDC surgery. DATA SOURCES: PubMed, Embase, and Cochrane databases. METHODS: Electronic databases were searched from their respective inception dates to January 2023. Data on surgical approach, patient demographics, surgical procedure, and postoperative outcomes were extracted and analyzed. The quality of the studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist. RESULTS: The literature search yielded nine articles published between 2011 and 2022. Overall, 85 patients in these studies successfully underwent endoscopy-assisted TGDC surgery using various approaches, including areolar, axillo-breast, transoral-vestibular, and transoral-sublingual. The operative time varied across the studies, ranging from 50 to 480 min. TGDC sizes ranged from 1 to 3 cm in diameter. Complications, including infection, skin bruising, and dysarthria, were reported in seven patients (8%). No cases of conversion to open surgery or postoperative recurrences were reported. CONCLUSION: Endoscopy-assisted surgery is a potential alternative for patients seeking TGDC resection with satisfactory aesthetic results while ensuring safety. However, existing evidence is insufficient to support the superior effectiveness of endoscopy-assisted TGDC surgery over the traditional Sistrunk procedure. Laryngoscope, 2024.
RESUMO
Subjective tinnitus is the perception of sound in the absence of external stimulation. Neuromodulation is a novel method with promising properties for application in tinnitus management. This study sought to review the types of non-invasive electrical stimulation in tinnitus to provide the foothold for further research. PubMed, EMBASE, and Cochrane databases were searched for studies on the modulation of tinnitus by non-invasive electrical stimulation. Among the four forms of non-invasive electrical modulation, transcranial direct current stimulation, transcranial random noise stimulation, and transauricular vagus nerve stimulation yielded promising results, whereas the effect of transcranial alternating current stimulation in the treatment of tinnitus has not been confirmed. Non-invasive electrical stimulation can effectively suppress tinnitus perception in some patients. However, the heterogeneity in parameter settings leads to scattered and poorly replicated findings. Further high-quality studies are needed to identify optimal parameters to develop more acceptable protocols for tinnitus modulation.
