Objectives:
To determine the prevalence, aetiology and predisposing factors in patients presenting with hoarseness to Usmanu Danfodiyo University Teaching Hospital, Sokoto.
Methods:
The study was a prospective, hospital-based study involving patients with hoarseness ≥7 years. Demographic characteristics and information on voice abuse, smoking, alcohol ingestion and gastroesophageal reflux disease (GERD) were taken. Participants had laryngeal endoscopy using a flexible nasopharyngolaryngoscopy to determine the cause of hoarseness.
Results:
A prevalence of 2.97% was obtained in the study, and the age range of participants was 7 to 78 years, with a male:female ratio of 1.3:1. The most common cause of hoarseness was laryngeal inflammation 38 (40.0%), followed by benign neoplasm 24 (25.3%) , malignancy 20 (21.1%) and trauma 10 (10.5%). Voice abuse, GERD and smoking were significant predisposing factors for benign neoplasm (χ2 = 8.73; P = 0.0031), inflammation (χ2 = 19.79; P < 0.0001) and malignancy of the larynx (χ2 = 10.66; P = 0.0011), respectively.
Conclusion:
The study showed that acute and chronic laryngeal infection and neoplasms (benign and malignant) of the larynx were the most common causes of hoarseness. Voice abuse, smoking and GERD were the commonest predisposing factors.

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,...
