Hypoglossal nerve palsy following suspension laryngoscopy: Case series

Abstract

Background: Suspension laryngoscopy (SL) is routinely used in operative laryngology. There is currently very little information in the literature about the complications of this procedure. One of the complications is hypoglossal nerve palsy. Objective: The aim of this article is to review four cases of hypoglossal nerve palsy post-SL. Materials and Methods: This is consecutive case series of four patients with hypoglossal nerve injury following SL. We discuss the presentations, management, and predisposing factors of the injury. Results: The majority of patients with hypoglossal nerve palsy were male and smokers or ex-smokers. All underwent SL using Lindholm suspension. Right-side hypoglossal nerve palsy was more common than that on the left side (three of four cases). The length of the operation was unrelated to this complication. Two cases had associated injuries including bruising over the right anterior pillar and uvula and ulceration over the lower lip. All patients were treated with three doses of intravenous dexamethasone, and the average recovery time was 2 weeks. Conclusion: Patients undergoing SL must be informed about the risk of temporary unilateral hypoglossal nerve palsy. Further study is necessary to investigate the predisposing factors.
