Postoperative sore throat is a frequent complication of general anesthesia, with incidence estimates ranging as high as 60–62% depending on definition, patient population, and airway device used (El-Boghdadly et al., 2016; Mazzotta et al., 2023). Although it is a relatively minor symptom, postoperative sore throat can cause discomfort and affect satisfaction, oral intake, and early mobilization during the recovery period. Understanding the trajectory of recovery, and the interventions that shorten or attenuate it, is therefore relevant to perioperative care beyond the immediate anesthetic encounter.
The natural course of postoperative sore throat is one of gradual resolution over the first 24 to 72 hours, though symptoms may persist for several days in a minority of patients, particularly children (El-Boghdadly et al., 2016). Symptom severity typically peaks in the early postoperative hours and declines progressively thereafter (Thomas & Beevi, 2007). Recovery is not uniform across the underlying pathology encompassed by the term postoperative sore throat, which includes pharyngitis, laryngitis, tracheitis, cough, hoarseness, and dysphagia; each may follow a different course to resolution (Mazzotta et al., 2023).
Pharmacological prophylaxis can significantly accelerate recovery. One study demonstrated that a single preoperative dose of 8 mg intravenous dexamethasone, a corticosteroid, reduced both the incidence (20% versus 56.3% in controls) and the severity of sore throat at every time point measured over 24 hours, both at rest and during effort. Subsequent meta-analyses have refined the dosing threshold, indicating that intravenous doses exceeding 0.1–0.2 mg/kg are required for clinically meaningful benefit, whereas lower doses are ineffective (El-Boghdadly et al., 2016; Mazzotta et al., 2023). The proposed mechanism, inhibition of phospholipase A2 and cyclo-oxygenase-2-mediated inflammatory mediator synthesis, takes several hours to manifest, which is consistent with the corticosteroid’s greater effect on later rather than immediate symptom scores (Thomas & Beevi, 2007).
Beyond steroids, recovery can be hastened by topical and adjunctive measures including benzydamine, lidocaine, magnesium, ketamine, and licorice gargles, each with varying evidence quality and modest absolute effect sizes (El-Boghdadly et al., 2016; Mazzotta et al., 2023). Non-pharmacological factors also influence the recovery trajectory: smaller tracheal tube size, limitation of cuff pressure, avoidance of blood staining on the tube, and gentler intubation technique (including reduced stylet extraction force) are all associated with faster and more complete symptom resolution (Mazzotta et al., 2023; El-Boghdadly et al., 2016).
Clinically, recovery from postoperative sore throat should be regarded as a predictable, largely self-limiting process that can be shortened through a combination of careful airway management and judicious prophylactic pharmacotherapy. Given that most interventions produce only modest reductions in symptom severity, reducing throat irritation through appropriate tube sizing and cuff pressure monitoring offers the most reliable path to a faster, more comfortable postoperative recovery.
