Otolaryngologic aspects of tetanus

Area of Science:

• Infectious Diseases
• Otolaryngology
• Public Health

Background:

• Tetanus remains a critical health issue in developing countries, causing approximately 1 million cases annually.
• The study focuses on the otolaryngological manifestations and prognostic factors of generalized tetanus.
• High mortality rates associated with tetanus underscore the need for improved diagnostic and management strategies.

Purpose of the Study:

• To evaluate presenting complaints, clinical findings, and otolaryngological symptoms in tetanus patients.
• To determine the correlation between clinical findings and prognosis in tetanus.
• To emphasize the importance of considering tetanus in patients with specific head and neck symptoms.

Main Methods:

• Retrospective analysis of 37 generalized tetanus patients treated between 1991 and 2001.
• Evaluation of presenting symptoms, clinical findings, wound assessment, and treatment interventions.
• Correlation analysis of clinical stage, incubation period, onset period, and mortality rates.

Main Results:

• Trismus, neck pain, and dysphagia were the most common presenting symptoms.
• A significant percentage of patients (27%) had no obvious or trivial wounds.
• Mortality rate was high at 59.4%, with shorter incubation/onset periods and higher disease grade significantly linked to mortality.

Conclusions:

• Clinical presentation, particularly trismus and dysphagia, requires a high index of suspicion for tetanus, irrespective of wound presence.
• Otolaryngologists should consider tetanus in patients presenting with trismus or subacute progressive dysphagia.
• Complete physical examination is essential, as patient complaints may not fully correlate with clinical findings.
