REVIEW METHODS: A literature search was conducted over a period from January 1990 to March 2020. The following search words were used either individually or in combination: voice disorders, laryngopharyngeal reflux, and gastroesophageal reflux. The search was conducted over a period of a month: April 2020.
RESULTS: Five clinical research were selected based on our objectives and selection criteria. Four studies were of level III evidence. Altogether, a total of 606 patients were pooled with male predominance of 63%. In all studies, reflux was suggested to have strong relation with dysphonia. Majority of cases used 24-h pH monitoring to confirm reflux which yielded positive results in 69%. The top three most common endoscopic findings include: interarytenoid erythema and edema (32/38), vocal cord erythema and edema (160/231) and postglottic edema (141/337). Vocal cord nodules were found in 28% of our patients. Acoustic analysis and perceptual assessment of voice was performed in only 1 study. No complication from any procedure was mentioned in any of the studies. Outcome of treatment was mentioned in 1 study, whereby after 4.5 months of follow-up, 68% of children showed improvement in symptoms.
CONCLUSION: Current evidence shows that there is strong relation between reflux and dysphonia in children. Most common laryngoscopic findings suggestive of reflux includes interarytenoid erythema and edema, vocal cord erythema and edema and postglottic edema.
CASE PRESENTATION: We described a 45-year-old female who presented with dysphagia, hoarseness and anterior neck swelling. The initial CT scan revealed a right thyroid abscess which was incised and drained with no malignancy found in the biopsy of the thyroid tissue. Patient presented one month later with worsening dysphagia, weight loss and a fungating anterior neck mass. Further investigation revealed a locally advanced hypopharyngeal squamous cell carcinoma extending to the right thyroid, upper oesophagus, prevertebral muscles and bilateral cervical lymph nodes (T4bN2cM0). Unfortunately, the patient passed away prior to initiation of treatment.
CONCLUSION: Clinicians should have raised index of suspicion of a possible underlying hypopharyngeal carcinoma in patients presenting with thyroid abscess and proceed to further investigations in order to ensure early diagnosis and treatment of the malignancy.
