Summary

Hyperventilation syndrome (HVS) is prevalent in patients with persistent nasal congestion after surgery. This condition, characterized by rapid breathing and low carbon dioxide levels, may not require further surgery.

Area of Science:

  • Otolaryngology
  • Pulmonology
  • Psychosomatic Medicine

Background:

  • Persistent nasal congestion despite adequate surgical outcomes and medical treatment is a common clinical challenge.
  • Hyperventilation syndrome (HVS) has not been widely recognized as a potential cause of such symptoms.

Purpose of the Study:

  • To evaluate the prevalence of HVS in patients experiencing ongoing nasal congestion post-nasal surgery.
  • To explore HVS as a differential diagnosis for refractory nasal obstruction.

Main Methods:

  • A prospective case series of 14 patients with persistent nasal congestion after surgery was conducted.
  • Patients were assessed for HVS, including respiratory rate, breathing patterns, and the Nijmegen questionnaire.
  • End-tidal P(CO2) levels were measured in three patients, and breathing retraining was administered to five.

Main Results:

  • All patients exhibited an elevated respiratory rate and upper thoracic breathing pattern.
  • Twelve of the 14 patients (85.7%) scored positive for HVS based on the Nijmegen questionnaire.
  • Measured end-tidal P(CO2) levels were low (≤35 mmHg) in the tested patients.

Conclusions:

  • HVS should be considered in the differential diagnosis of patients with persistent nasal congestion, especially after unsuccessful nasal surgery.
  • Low arterial P(CO2) levels and altered neuromuscular activity may contribute to nasal symptoms in HVS patients.
  • Further surgical intervention may not be the optimal solution for nasal congestion in patients with HVS.
