A comparative study of transcervical, endoscope‐assisted transcervical, and endoscope‐assisted transoral resection of retrostyloid space schwannomas

Abstract

BackgroundThe aim of this retrospective study was to compare the efficacy of transcervical (TC), endoscope‐assisted transoral (TO), and endoscope‐assisted TC for resection of retrostyloid space schwannomas.MethodsThe study included patients who underwent complete resection of schwannomas by only one surgical approach. The data we collected included tumor size, estimated blood loss, postoperative complications, and so on. Statistical analysis was performed using one‐way analysis of variance and Fisher's exact test.ResultsThe study collected 85 patients with tumors mostly located at the oropharyngeal level who were followed up 6 months at least. The results showed that endoscope‐assisted TO had certain advantages over others. Additionally, the endoscope‐assisted TO set the lowest incidence of neurological complications.ConclusionOur findings demonstrate that for team with rich experience in the skull base surgery, endoscope‐assisted TO is a superior option compared to the other two groups for resection of retrostyloid space schwannomas, with the better preservation of neurological function.
