Objective:
To investigate the clinical characteristics and prognosis of herpes zoster laryngitis with vocal fold immobility.
Study Design:
Retrospective study.
Methods:
Clinical characteristics, laryngeal signs on strobolaryngoscopy, imaging examination findings, and outcomes of patients were analyzed retrospectively.
Results:
This study included 17 patients (11 males [64.7%] and six females [35.3%]), with a mean age of 63.3 ± 6.7 years. The primary symptoms were hoarseness (94.1%), dysphagia (76.5%), pharyngalgia on one side (76.5%), and aspiration (70.6%). No patient had skin herpes of the head and neck. The duration of symptoms was 5-30 days (median: 10 days). Twelve patients (70.6%) were in an immunocompromised state before the disease. Strobolaryngoscopy showed congestion and swelling of the mucosa on one side of the larynx, with whitish eruptions on the supraglottic mucosa and ipsilateral vocal fold immobility. Five patients (29.4%) exhibited signs of ipsilateral accessory nerve injury. The imaging examination showed supraglottic inflammatory changes in 12 patients (70.6%). Among the 14 patients whose treatment could be clearly described, only one patient received antiviral treatment, whereas others received neurotrophic and symptomatic treatment. Notably, all patients demonstrated good outcomes because their symptoms eventually returned to normal.
Conclusion:
Herpes zoster laryngitis is caused by varicella-zoster virus infection of the vagus nerve. It is characterized by laryngeal herpetic changes on one side and unilateral vocal fold immobility. The inducement of the disease tends to be associated with the abnormal immune state of patients. It can be easily misdiagnosed because of the absence of skin herpetic changes. Regardless of antiviral therapy, patients generally exhibit a favorable outcome.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...
01:23Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
