Background and Objectives : This study evaluated the efficacy of combination therapy of proton pump inhibitor (PPI) and steroid inhaler (SI), with or without botulinum toxin injection (BTX) for contact granuloma. Subjects and Methods : Fourteen contact granuloma patients were enrolled in this study. Combination therapy of PPI and SI were used for the first line treatment. When combination therapy was not effective, BTX was performed as the second method. Treatment results were recorded as responsible or non-responsible. Farwell grade, size, history of voice abuse, gender, and reflux finding score (RFS) were compared between responsible group and non-responsible group. Results : Initial response rate was 28.6% after treatment of PPI and SI. BTX was performed on three un-responsible patients. After BTX injection, three patients had complete remission of granuloma. Final response rate was 50.0%. Un-responsible group had significantly higher RFS than responsible group. Conclusion : The efficacy of PPI and SI was limited for contact granuloma in this study. Botulium toxin injection was recommended in early phase when PPI and SI did not effective for contact granuloma. Prospective studies evaluating the effects of PPI and SI are warranted.

Background and Objectives Proton pump inhibitors (PPIs), mucolytics, and steroids were commonly recommended after phonomicrosurgery to prevent worsening of vocal fold (VF) scar formation and subglottal swelling. However, there is no consensus about whether laryngeal reflux and thick discharge are associated with the voice outcomes following phonomicrosurgery in benign VF lesions. The purpose of this study is to examine voice outcomes of use of PPIs, mucolytics,and steroids after phonomicrosurgery. Materials and Method This randomized controlled study is performed with patients undergoing laryngomicroscopic surgery for VF polyp and cyst. Participants were randomly assigned to 1) no medication, 2) PPIs, 3) PPIs+mucolytics, and 4) PPIs+mucolytics+steroids for 2 months postoperatively. Grade, roughness, breathiness, asthenia, and strain (GRBAS) scale, stroboscopic examination, aerodynamic assessment, acoustic analysis, and Voice Handicap Index-10 (VHI-10) were performed pre- and post-operatively at 2 months. Parameters were compared among four groups. Results Among 85 patients, a total of 50 patients were included. The VHI-10, perceptual and acoustic parameters improved in all groups after surgery. However, there was no significant difference in those parameters among all groups. Conclusion PPIs, mucolytics, and steroids did not significantly influence voice outcomes after phonomicrosurgery in patients with benign VF lesions.

Background and Objectives Globus pharyngeus is one of the most common symptoms of patients visiting otorhinolaryngology out-patient clinic, and usually long-lasting, difficult to treat, and frequently recurrent. Mucomyst^®, N-acetyl cysteine is an inhalation agent mainly used for mucolysis and reducing inflammation in airway via antioxidative effect. The purpose of this study was to evaluate the efficacy of inhaled Mucomyst^® treatment in patients with globus pharyngeus refractory to proton pump inhibitor (PPI). Materials and Method We prospectively evaluated the efficacy of Mucomyst^® in relieving symptoms of globus pharyngeus refractory to PPI in nine medical centers. Three hundred and three patients enrolled and finally 229 patients finished the inhaled Mucomyst^® therapy for 8 weeks. We analyzed the change of Reflux Symptom Index (RSI), Reflux Finding Score (RFS), Visual Analogue Scale (VAS) for globus, and Globus Pharyngeus Symptom Scale (GPS) after use of Mucomyst^® for 4 and 8 weeks. Results The GPS, RSI, RFS, and VAS score significantly decreased serially in patients who finished 8 week-inhalation treatment. The GPS improvement gap was significantly correlated with initial GPS (p<0.001) in multiple regression analysis. Conclusion Inhaled Mucomyst^® therapy was effective for the reduction of both subjective and objective findings in refractory globus patients. This study might suggest new treatment option for patients with globus. However, further thorough studies would be needed to assess the real effect of inhaled Mucomyst^® treatment as a standard treatment for globus.

Background and Objectives Vocal process granulomas (VPGs) are benign lesions of the larynx, typically contact granulomas (CG) and intubation granulomas (IG). The two diseases are known to have different clinical manifestations despite having the same pathological features. The purpose of this study was to analyze the treatment results for CG and IG and to obtain clinical information. Materials and Method We retrospectively reviewed the medical records of patients diagnosed with VPG between January 2015 and December 2018. The patient's age, sex, medical history, lesion size, lesion type, reflux finding score, response to treatment, duration of treatment, and follow-up period were compared. Results In total, 32 patients were included in the study, of which 18 were CG and 14 were IG. In the CG group, males were dominant (n=15, 83.3%), whereas in the IG group, females were dominant (n=11, 78.6%) (p=0.0009). The response to medical treatment using proton pump inhibitor and steroid inhaler was better in the IG group (11/14, 78.6%) than in the CG group (7/18, 38.9%) (p=0.036). Of the 14 patients who did not respond to medical treatment, 5 received botulium toxin injections, and all 5 had complete remission. The duration of medical treatment was significantly longer in the IG group (p=0.0029). Conclusion IG was more common in female, and CG was more dominant in male. IG had better response to medical treatment using proton pump inhibitor and steroid inhaler than CG.
