ABSTRACT
Aim: This systematic review and meta-analysis of randomized controlled trials (RCTs) compare the impact of platysma muscle layer closure technique among patients undergoing thyroidectomy in terms of postoperative outcomes, specifically pain. Methods: Five electronic databases (PubMed, Scopus, Web of Science, Google Scholar, and Cochrane Central Register of Controlled Trials) were searched from inception until July 22, 2023. The Cochrane risk of bias tool 2 was employed for risk of bias (ROB) assessment. Data were pooled as mean difference (MD), standardized MD (SMD), or risk ratio (RR) based on data type (continuous or dichotomous) using RevMan software. Results: This meta-analysis included four RCTs with a total of 426 patients. Three RCTs had a low risk of bias, while one had some concern regarding bias. The overall MD of the postoperative pain score favored the non-closure group over the closure group (MD = 0.63; 95% CI: [0.09, 1.18]; P = 0.02). However, no significant differences were observed between the two groups in terms of patient scar assessment scale (MD= -0.61; 95% CI: [-3.39, 2.17]; P = 0.67), observer scar assessment scale (SMD = 0.26; 95% CI: [-0.30, 0.81]; P = 0.37), length of the scar (MD = 0.27; 95% CI: [-0.12, 0.67]; P = 0.17), wound infection (RR = 0.63; 95% CI: [0.13, 3.16]; P = 0.57), and seroma or hematoma (RR = 3.00; 95% CI: [0.49, 18.55]; P = 0.24). Conclusion: Our findings suggest that the platysma muscle layer closure during thyroidectomy might lead to increased postoperative pain but does not significantly impact scar outcomes or postoperative complications.

ABSTRACT
INTRODUCTION AND IMPORTANCE: Schwannomas are tumors of the nerve sheath that consist of Schwann cells that are often described as slow-growing. Glossopharyngeal schwannomas are rare tumors present in the region of the posterior fossa, with limited case reports present in literature. While patients may present asymptomatically, some present with vestibulocochlear symptoms or lower cranial nerve dysfunction. CLINICAL PRESENTATION: We report an extremely rare case of a left para-pharyngeal carotid space glossopharyngeal schwannoma in a 26-year-old female. The presentation was a 3-month left sided neck swelling and a hoarse voice. Radiological investigations were completed (neck ultrasound; CT; MRI scans). Investigations revealed a solid lesion measuring about 29 × 10 mm. The final decision was to excise the mass under microsurgery. CLINICAL DISCUSSION: CN 9-11 schwannomas are often called jugular foramen schwannomas. Intraoperatively, these get differentiated as glossopharyngeal schwannomas. Diagnosis involves a physical examination, a detailed history, audiological assessments, and radiological investigations. While MRI scans are known as the most effective pre-operative diagnostic test, cases are in majority discovered intra-operatively. Surgical excision is the recommended approach. Post-operative recurrence is rare. Pre-operative diagnosis is often difficult due to the rarity and similarly presenting differential diagnoses. CONCLUSION: Schwannomas of the glossopharyngeal nerve are extremely rare tumors that may present with lower cranial nerve or vestibulocochlear deficits. Magnetic resonance imaging is a useful tool in diagnosing this unordinary tumor. This case report intends to provide further data regarding the clinical presentation, the patient population, and the diagnostic and surgical approach in dealing with this incredibly rare tumor.
