Abstract
Laryngeal granuloma, vocal process granuloma, or post-intubation granuloma are benign, inflammatory lesions of the arytenoid cartilage vocal process. The etiology of laryngeal granulomas is multifactorial, such as chronic irritation due to endotracheal intubation, vocal cord injury or trauma, and gastroesophageal reflux disease. They can arise postoperatively after mucosal injury due to orotracheal intubation. Clinical manifestations include voice change and dyspnea, which may start one to four months after extubation and may rarely lead to asphyxia. We presented a case of death due to glottic granuloma occurring after a surgical procedure to remove a laryngeal polyp attributed to previous laryngeal injuries by multiple intubations.

[PMID: 38604901 DOI: 10.1016/j.jvoice.2024.03.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2024] [Revised: 03/21/2024] [Accepted: 03/22/2024] [Indexed: 04/13/2024]
Abstract
OBJECTIVES The aim of this study was to assess published systematic reviews that discussed noninvasive management of voice disorders. An umbrella review was conducted to collect, organize, and summarize narratively all available pharmacologic and voice therapy interventions. STUDY DESIGN Umbrella review of systematic reviews. METHODS Pertinent systematic reviews were identified by searching Pubmed/Medline and Embase. A primary screen identified studies related to voice. The second round of screening focused on studies that involved noninvasive management of voice disorders such as pharmacologic or voice therapy interventions. Variables of interest included study design, number of studies included in the review, target population, method of intervention, and outcomes. RESULTS Forty-three systematic reviews were eligible and included in the umbrella review. Ten studies focused on pharmacologic interventions, and 33 studies focused on voice therapy. Individual studies included in the systematic reviews ranged from 2-47, with a total of 601 studies overall. CONCLUSIONS This study provides a detailed review of all available systematic reviews on noninvasive management of voice disorders. Explored medications included proton pump inhibitors, calcium channel blockers, tricyclic antidepressants, antibiotics, corticosteroids, and hormone replacement. Explored voice therapy techniques included hydration, vocal function exercises, laryngeal manual therapy, respiratory exercise, biofeedback, phonation, coping strategies, and others. This may be utilized to guide therapeutic decision-making and identify current gaps in the literature that may warrant future investigation.

Abstract
OBJECTIVES To assess and compare the effectiveness of various treatment approaches for laryngeal contact granulomas (LCG). METHODS A retrospective analysis was conducted on a cohort of 45 patients diagnosed with LCG at the Second Affiliated Hospital of Xi'an Jiaotong University from October 2017 to May 2023. Based on the treatment modalities administered, patients were categorized into three groups: acid suppression alone, hormone injection combined with acid suppression, and surgery combined with acid suppression. Subsequently, the study compared differences in treatment efficacy and average healing time among these three groups, using various indicators. RESULTS The findings indicate that the granuloma size in LCG patients with hoarseness (0.126, 95% CI 0.087-0.288) was significantly greater compared to LCG patients without hoarseness (0.047, 95% CI 0.014-0.083) (P = 0.001). However, there were no significant variations in age, morphology (unlobulated/lobulated), laterality ratio (left/right), sex ratio (male/female), history of tracheal intubation (non-intubation/intubation), and RFS score (RFS > 7/RFS ≤ 7) (P > 0.05), regardless of the presence of hoarseness symptoms. At the treatment observation endpoint of 3 months, the curative ratio in the group receiving hormone injection combined with acid suppression was found to be significantly higher compared to the group receiving acid suppression alone (P = 0.018). In addition, the average healing time of patients in the hormone injection combined with acid suppression group was notably shorter than that of the acid suppression alone group (P = 0.007). CONCLUSIONS The combination of hormonal injections and acid suppression may enhance the curative ratio and expedite the healing time of LCG. LEVEL OF EVIDENCE: 4

Abstract
OBJECTIVE Laryngeal contact granuloma (LCG) is a relatively uncommon disease with chronic inflammatory stimulation, and long-term reflux irritation is a vital factor for arytenoid cartilage calcification. Our investigation compared the severity of ipsilateral arytenoid cartilage calcification with the frequency of recurrence of LCG after surgical treatment. METHODS A retrospective chart review of prospectively gathered data over five years from 327 patients, including 153 subjects without laryngeal lesions, were age- and sex-matched normal controls, 103 patients with various other vocal cord lesions were in the laryngeal lesion group and 71 LCG patients met the diagnostic criteria pathologically. All subjects underwent laryngeal high-resolution computed tomography (HRCT) prior to therapeutic interventions. The computed tomography (CT) value and arytenoid cartilage calcification were obtained using image data before surgery, and their clinical significance was further analyzed. RESULTS Seventy-one patients with LCG, including sixty-two males, were enrolled in the study. Among these cases, there were 67 patients with unilateral vocal cord lesions. Of the 103 eligible patients in the laryngeal lesion group, 87 had unilateral lesions, which including eighty-seven men. Of the 153 average subjects, 105 were male. The rate of arytenoid cartilage calcification in the LCG group was dramatically higher in the lesion side than in the laryngeal lesions and normal group (P < 0.01). Furthermore, the CT value (P < 0.01) and range of calcification (P < 0.01) were significantly higher in patients with LCG than in those with laryngeal lesions. Importantly, patients with high CT values and the calcification range of lesions in the arytenoid cartilage displayed a greater lesion size and recurrence rate than patients with low CT values and lesion areas (P < 0.01). CONCLUSION Our results suggest that most patients with LCG present with calcification of the arytenoid cartilage. The more severe the calcification in the arytenoid cartilage, the greater the risk of granuloma size and recurrence in LCG after surgical treatment. CT and bone density testing of the arytenoid cartilage may be an essential method to evaluate the prognosis of LCG.

Abstract
OBJECTIVES Vocal process granulomas (VPGs) are benign laryngeal lesions that may manifest as ulcerated regions of the vocal fold or nodular polypoid lesions. Gold standard treatments for idiopathic VPG are yet to be established at this time. This study evaluated clinical decision-making and outcomes in the treatment of VPG patients based on experiences of academic laryngologists across the United States. METHODS A 21-question survey was developed to evaluate each respondent's specific VPG patient population, clinical decision-making in treating VPG, and corresponding treatment outcomes. The survey was distributed to 168 laryngologists at academic institutions across the United States. Data were analyzed through the Qualtrics platform. RESULTS A total of 106 responses were analyzed, with a completion rate of 63.1%. Etiology of VPG was most commonly attributed to phonotrauma (96.2%) and reflux (71.8%). Primary first-line treatment was most commonly antireflux medications (92%). Other common first line treatments included voice therapy (58.8%) and inhaled steroids (42.5%). With these treatments, the majority of laryngologists report that recurrence is uncommon (68.4%). Dysphonia was cited as the most frequent long-term sequelae at 27.8%. CONCLUSIONS VPG treatment strategies continue to be controversial across the United States with many treatments described in the literature with variable application in the practice of academic laryngologists today. Based on survey results, antireflux medications and voice therapy may be the most widely used and most effective treatment options. Establishment of gold standard therapy for VPG as well as further research into recurrent or persistent VPG despite antireflux and voice therapy should be explored.

Abstract
OBJECTIVE The objective of this study was to evaluate the efficacy of anti-reflux therapy on the idiopathic vocal process granulomas. METHOD This was a prospective case series study. The patients with vocal process granulomas who met the inclusion criteria were analysed. Proton pump inhibitors and vocal hygiene education were conducted for 8-20 weeks. RESULTS Of the 16 patients with vocal process granulomas, 5 (31.25 per cent) patients achieved complete remission. The complete remission rate of granulomas was not significantly related to age (p = 1.000), sex (p = 0.296), side (p = 0.299), position (p = 0.100), endoscopic morphology (p = 0.263) or proton pump inhibitor treatment course (p = 0.543) but was significantly associated with granuloma location (p = 0.001) and granuloma size (p = 0.012). CONCLUSION Granulomas in the vocal cord and the margin of the vocal process had an excellent response to proton pump inhibitors, but granulomas on the surface of vocal process and arytenoid cartilage body had little response to proton pump inhibitors. The prolonged period of proton pump inhibitor treatment did not increase the complete remission rate of vocal process granulomas.

Abstract
OBJECTIVE This retrospective study was undertaken to assess the outcome of the medical and/or surgical management of patients presenting with clinical features of arytenoid granuloma. METHODS The records of 53 males and 9 females were reviewed for predisposing factors, types of treatment received and recurrence following the treatment. RESULTS Most of the patients (48 out of 62, 77.4 per cent) were treated conservatively with medical management and voice therapy, which resulted in complete resolution of arytenoid granuloma in over two-thirds of the patients treated (32 out of 48, 66.6 per cent). Overall, 28 patients (out of 62, 45.1 per cent) required surgery (14 failed medical treatment cases and 14 surgery as first-line treatment cases). Of these, five patients (out of 28, 17.9 per cent) had recurrence, and were managed with revision surgery and concurrent local injection of Botox. CONCLUSION Anti-reflux medication and voice therapy are effective first-line management options. Pre- and post-surgery adjuvant treatment improves the results of surgery. Local injection of Botox was successful in the treatment of failed surgical cases.

Abstract
OBJECTIVE To identify the factors predicting postoperative recurrence after cold steel excision for the market trader with idiopathic vocal process granulomas (VPGs). MATERIAL AND METHODS The market traders with idiopathic VPGs who do not respond to medical treatment were treated by cold steel excision. The factors considered likely to affect the recurrence were evaluated by univariate and multivariate logistic regression. RESULTS The total of 80 idiopathic VPGs underwent the cold steel excision. All postoperative 6 months, the complete remission rate was 37.5% (30 VPGs) and 50 recurrences developed (62.5%). The recurrence rate was not significantly associated with sex (P = 0.119), side (P = 0.468), VPG size (P = 0.726), LPR (P = 0.293), diabetes mellitus (P = 0.5611), cerebrovascular disease (P = 0.129), or chronic pulmonary disease (P = 0.190). Multivariate logistic regression showed that only vocalization frequency (P = 0.006) and smoking and alcohol consumption (P = 0.001) were independent predictors of recurrence. There was no significant correlation between age and recurrence (P = 0.59). However, recurrence was more common in those aged 51-60 years than those aged ≥61 years (P = 0.019). Of the recurrent 49 VPGs treated conservatively via behavioural modification and oral deanxit, the granulomas disappeared spontaneously in 38 (77.6%) within 6-10 months and in 11 (22.4%) within 2-3 years. CONCLUSIONS The market traders with VPG would be a high recurrence rate after cold steel excision, the frequency of voice use and smoking and alcohol consumption were significant independent predictors of recurrence. Antidepressant medications and behavioural modification could effectively improve the outcome of VPG.

Abstract
PURPOSE Esophagectomy is a highly invasive procedure, associated with several postoperative complications including pneumonia, anastomotic leakage, and sepsis, which may result in multiorgan failure. Pneumonia is considered a major predictor of poor long-term prognosis, so its prevention is important for patients undergoing surgery for esophageal cancer. METHODS The subjects of this study were 137 patients who underwent esophagectomy at Keio University Hospital, Tokyo, Japan, between January, 2012 and December, 2016. Patients who underwent R0 or R1 resection or esophagectomy with organ excision were included. Patients who underwent salvage surgery or resection of recurrent laryngeal nerve, and those with preoperative recurrent laryngeal nerve palsy, were excluded. We investigated the effect of the maximum phonation time on the development of postoperative pneumonia. RESULTS Pneumonia developed more frequently in patients with a long operative time, clinically left recurrent nerve lymph node metastasis, and a short preoperative maximum phonation time (p = 0.074, 0.046, and 0.080, respectively). Pneumonia was also more common in men with an abnormal maximum phonation time (p = 0.010). CONCLUSIONS The maximum phonation time is a significant predictor of postoperative pneumonia after esophagectomy in men.

Abstract
Objective:The aim of this study is to investigate the effect of surgical resection of idiopathic laryngeal contact granuloma on the follow-up treatment. Methods:From April 2014 to December 2019, the clinical data of 390 male patients with idiopathic laryngeal granuloma treated were analyzed retrospectively. The patients were divided into the group with history of surgical resection (172 patients) and the group without surgical resection history (218 patients), and then both received the combined therapy. The treatment efficacy of the two groups were compared. Results:By the end of 6 months after beginning the combined therapy, the total efficacy rate of the patients with a history of surgery was 71.5%(123/172), and that in patients without a history of surgery was 97.7% (213/218). The difference between the two groups was statistically significant(Z=-7.828, P=0.0001). Among the cured patients, the cure time of patients without the surgery history was shorter than patients with surgery history(Z=-4.441, P=0.0001). Conclusion:Surgical treatment of laryngeal contact granuloma increases the difficulty of follow-up treatment, so surgical treatment is not recommended for newly diagnosed patients with laryngeal contact granuloma.
