Vocal trauma especially in females and children is a potent risk factor for vocal fold nodules and cysts. The gastroesophageal reflux is a suggested risk factor for Reinke's edema and contact granuloma. Smoking is the risk factor for MAPLs particularly polyp, contact granuloma, and Reinke's edema. Also, alcohol consumption is a possible risk factors for Reinke's edema.

Abstract

OBJECTIVE: To identify the possible risk factors related to etiology of the minimal associated pathological lesions (MAPLs) of the vocal folds and their impacts on the recurrence of lesion.

METHODS: This analytical cross-sectional study included 200 subjects presented with dysphonia to the Phoniatrics/Voice Clinics in two hospitals in Gulf region (KSA and UAE). Same number of matched voluntaires from the same hospitals (hospital staffs, employees and their relatives) and relatives of subjects with typical voice quality were included as well. Both groups underwent a simple questionnaire consists of 15 items related to previously accused risk factors of MAPLs.

RESULTS: The bivariant analysis by Fisher's exact test showed that male gender, presence of kids, misuse of voice, alcohol, gastroesophageal reflux diseases and voice handicapping are associated with significant risk to have MAPLs with P values < 0.001 for all except for alcohol (P = 0.015). Welch's t test revealed higher smoking index in subject than control groups with significant difference (P < 0.001). In contrast, spices, family shouting and nearby industry were not potent risk factors in our study group.

CONCLUSION: Vocal trauma especially in females and children is a potent risk factor for vocal fold nodules and cysts. The gastroesophageal reflux is a suggested risk factor for Reinke's edema and contact granuloma. Smoking is the risk factor for MAPLs particularly polyp, contact granuloma, and Reinke's edema. Also, alcohol consumption is a possible risk factors for Reinke's edema. Identification of risk factors of the MAPLs is an important step in planning therapy. Risk factors which are highly related to a specific type of MAPLs should be involved in any planned program for protection, voice rehabilitation and/or prevention of recurrence of that lesion.
