Pyogenic granuloma in larynx is very rare. It is benign disease, and histopathologically it looks like capillary-rich hemangioma. The most common etiology of pyogenic granuloma is laryngeal trauma, usually related to intubation. It can be treated with speech therapy, medication, or surgical resection. We experienced a case of large pyogenic granuloma in larynx with feeding vessels of a 24-year-old woman. When she visited us, she suffered from dyspnea. We had performed excision of laryngeal mass by laryngeal microsurgery emergently. She was diagnosed with pyogenic granuloma in larynx after operation.

Laryngeal granuloma following endotracheal anesthesia was reported as traumatic granuloma of the larynx by Clausen in 1932. Thereafter Harrison reported that 4% of the intubated cases developed larynx and upper respiratory tract injuries and 1% of the above mentioned injured cases later developed laryngeal granuloma with symptoms including voice change and even dyspnea in severe cases. The endotracheal intubation has been wedely used for general anesthesia or patency of the air way .and the reported cases of the laryngal granuloma Fig. 5. as its complication have been increased in number worldwidely. For a year from March 1975 to Feb. 1976, the authors have experienced the nine cases of laryngeal granuloma in our department and this is the report of clinical findings on these cases along with literature review.

Among lesions in the larynx, laryngeal contact granuloma due to persistent tissue irritation can typically be attributed to endotracheal intubation, vocal abuse, or gastro-esophageal reflux disease. Treatment typically includes voice therapy, lifestyle changes and use of anti-reflux medication. Microsurgical removal is only indicated in cases of severe dyspnea due to mass size. Foreign body granuloma is a response of to any foreign material in the tissue. Foreign body granulomas are sometimes misdiagnosed as soft tissue tumors when the causative foreign body is not initially found. Delayed treatment of these foreign bodies may cause complications. We present a case of larynx granuloma due to impacted foreign body, probably fish bone, in the larynx that mimicked contact granuloma. We initially used anti-reflux medication, but to no avail. The laryngeal mass, observed through laryngoscopy, showed no improvement and therefore necessitated a proper pathologic diagnosis. We were able to successfully treat it via trans-oral laser CO2 microsurgery before any complications developed.

Organophosphates are used as herbicides. Glyphosate is one of the acidic organophosphate solution of pH4.8-6. We experienced a case of laryngeal injury after glyphosate caustic ingestion. He had a mild respiratory distress, and a laryngeal granuloma was observed in endoscopy. He received treatment with oral steroid and PPI for two weeks, the laryngeal granuloma and respiratory distress were nearly disappeared. Therefore, we expect this case report to be helpful the therapeutic formulations in the damage of larynx due to glyphosate.

Background and Objectives : Laryngeal contact granuloma is benign inflammatory disease induced by excessive mechanical contact of larynx such as endotracheal intubation, voice abuse, laryngeal microsurgery as well as laryngopharygeal reflux. Because it is caused by various risk factors, multiple treatment modalities are required. The purpose of study is to evaluate treatment effect of topical steroid through nasal cavity in contact granuloma. Materials and Method : Fifty-two patients were enrolled in this study with exception of intubation granuloma. Patients were classified with four groups (Proton pump inhibitor (PPI), Nasal steroid spray (SPR), PPI+SPR, Observation) according to treatment modality. Results : Patients who treated with PPI (Odds ratio 2.45, p=0.03) and combination of PPI and SPR (Odds ratio 2.88, p<0.01) had significantly better response than patients who not treated with medical therapy. Conclusion : Combination therapy of nasal steroid spray and PPI is effective for contact granuloma of larynx and considered as a treatment of choice rather than PPI only treatment.

Introduction: 585 nm Pulsed dye laser (PDL) laryngeal surgery is based on the photodynamic characteristics of selective photothermolysis and photoangiolysis and recently considered to be the treatment for a variety of benign laryngeal disease. Objective: To review the indications and outcome of office-based 585nm PDL surgery and summarize new developments. Method: Retrospective study involving 402 patients was performed, The PDL surgery could be applied to various laryngeal diseases such as laryngeal papilloma, vocal fold dysplasia, laryngeal granuloma, vocal polyp, capillarectasia, scarred vocal fold and sulcus vocalis. Results : The physiologic properties of the vascular specificity of PDL provide many advantages and appear to be effective for laryngeal treatment. The PDL resulted in precise, selective coagulation of the microvasculature without damage to the surrounding tissue. Therefore PDL surgery is safe and effective for office-based treatment of benign laryngeal disease and for all patients regardless of their overall medical condition. Conclusion: PDL surgery provides potential benefits and advantage for treating common benign laryngeal disease.

Background: Laryngeal contact granuloma is an inflammatory hypertrophic granulation tissue arising at around the vocal process of arytenoid cartilage. Various approaches are currently used for the treatment, but a solid guideline has not been established. Objectives: We aimed to compare the each treatment modality in the hope of suggesting a guideline for the successful management of laryngeal contact granuloma. Method: Eighty-seven treatment cases of 56 patients were analyzed. Cases having recent intubation history were excluded from the study. All patients received vocal hygiene education. Proton pump inhibitors (PPI, N = 33) or H2 receptor antagonists ($H_{2}RA$, N =26) were used as a first-line treatment. Among the non-responders to $H_{2}RA$, 11 cases received PPI as a second-line therapy. Eight cases received botulinum toxin injection and 9 cases had laryngomicrosurgical removal. Results: As an initial therapy, response rate to PPI and $H_{2}RA$ was 60.6% and 38.5% respectively, which was not statistically different (p=0.091). Response rate of PPI as the second-line therapy was 36.3% (p=0.162 when compared to that of first-line PPI therapy). Response rate of Botulinum toxin injection was 75%. All cases of surgical removal recurred in a relatively short period (mean 1.9months). Conclusion: In patients having laryngeal contact granuloma, combined therapy with vocal hygiene education and PPI medication would provide more than 60% of therapeutic response. Botulinum toxin injection is highly effective even in non-responders to antireflux therapy. The only indications of surgery are to resolve diagnostic doubt or to treat acute airway compromise.

Pyogenic granuloma is very uncommon disease. It is a benign, elevated, and capillary-rich lesion occupying on the skin and mucous membranes, and is a reactive lesion, an overgrowth of granulation tissue. And this lesion may grow rapidly and can recur frequently. Pyogenic granuloma usually occurs on the lip, tongue, oral mucosa, and nasal mucosa. But, pyogenic granuloma of vocal cords is very rare. Recently, we experienced a case of pyogenic granuloma of a 48-year-old man who had been presented with hoarseness for 3 months. He was diagnosed pyogenic granuloma after laryngeal microscopic surgery. So we report this rare case with review of literatures.

Laser is a relatively recent addition to laryngeal surgery. Since their invention, laser use and applications have expanded rapidly. The use of lasers in surgery has offered a time- and cost-efficient alternative to cold surgical techniques and has been used in the treatment of numerous laryngeal pathologies, including stenoses, recurrent respiratory papillomatosis, leukoplakia, nodules, malignant laryngeal disease, and polypoid degeneration (Reinke's edema). Despite the notable benefits, laser surgery is not without disadvantages. Laser heat can increase scarring and cause damage to adjacent tissue. With laser laryngeal microsurgery, there is potential for airway fire, endolaryngeal bleeding, perichondritis, chondritis, granuloma, surgical emphysema, laryngeal stenosis and web formation, postoperative edema and swallowing problem. Surgeons should be known about these complications and could manage properly.
