Reflux laryngitis produces -a) Sub- glottic stenosis b) Ca larynxc) Cord fixationd) Acute supra- glottitise) Laryngitis
There are lots of controversies regarding the reflux laryngitis secondary to reflux gastrointestinal disease. But now some studies document that there is a clear relation between the two.
Reflux laryngitis may have the following sequlae:

– Bronchospasm
– Chemical pneumonitis
– Refractory subglottic stenosis 
– Refractory contact ulcer
– Peptic laryngeal granuloma
– Acid laryngitis (Heart burn, burning pharyngeal discomfort, nocturnal chocking due to interarytenoid pachydermia)
– Laryngeal Carcinoma (According to recent reports laryngeal reflux is the cause of laryngeal carcinoma in patients who are life time non-smokers).
Laryngopharyngeal Reflux
Here classical GERD symptoms are absent. Patients have more of daytime/upright reflux without the nocturnal/supine reflux of GERD. In laryngopharyngeal reflux esophageal motility and lower esophageal sphincter is normal, while upper esophageal sphincter is abnormal. The traditional diagnostic tests for GERD are not useful in LPR.
Symptom Chronic or Intermittent dysphonia, vocal strain, foreign body sensation, excessive throat mucus, Postnasal discharge and cough. Laryngeal findings: Interarytenoid bunching, Posterior laryngitis and subglottic edema (Pseudosulcus)
Sequelae of Laryngopharyngeal Reflux 

Subglottic stenosis
Carcinoma larynx
Contact ulcer/granuloma
Cricoarytenoid joint fixity
Vocal nodule/polyp
Sudden infant deaths
Laryngomalacia (Association)

Treatment is in similar lines as GERD, but we need to give proton pump inhibitors at a higher dose and for a longer duration (at least 6–8 months).
