RESUMO
OBJECTIVE: To explore the factors affecting the therapeutic efficacy of laryngeal contact granuloma. METHODS: The clinical data of 534 patients with laryngeal contact granuloma treated in our hospital from April 2014 to December 2019 were studied. The multivariable logistic regression was performed to find the risk factors influencing the treatment efficacy. RESULTS: Multivariable logistic regression showed that factors related to therapeutic efficacy were granuloma size (P = 0.0006) and gender (P = 0.0299) in conservative treatment group; laryngopharyngeal reflux (P = 0.0115), cough (P = 0.0124), and previous surgical history (P < 0.001) in combined treatment group. The surgical treatment had the worst therapeutic efficacy compared with combined treatment and conservative treatment. In the larger granuloma size subgroup, combined treatment showed better results than conservative treatment. CONCLUSION: Granuloma size and gender affect the therapeutic efficacy of conservative treatment. Previous surgical history, laryngopharyngeal reflux, and cough affect the therapeutic efficacy of combined treatment. Combined treatment is better than conservative treatment alone and surgical treatment shows the worst efficacy.

BACKGROUND: Transoral thyroidectomy can be performed using nasal or oral intubation. Recently, we encountered two cases of vocal cord granuloma that were suspected to result from intraoperative compression by the oral endotracheal tube. CASES PRESENTATION: Two women underwent transoral endoscopic thyroidectomy with oral endotracheal tubes fixed at the mouth angle. Their initial postoperative recovery was uneventful, but they developed hoarseness 2 months after the surgery. Subsequent strobolaryngoscopy revealed vocal cord granulomas at the side of contact of the endotracheal tube. One patient received medication and voice therapy, and her granuloma shrank significantly one month later. The other patient underwent granuloma resection. Thereafter, the symptoms improved in both the patients. CONCLUSIONS: Oral intubation with tube placement at the mouth angle might result in the formation of vocal cord granulomas. Therefore, we suggest positioning the tube at the midline to avoid excessive irritation on one side of the vocal cord.

OBJECTIVE: Despite the fact that there are many treatment alternatives, laryngeal contact granuloma has a high tendency of persistence, spontaneous disappearance without treatment, and recurrence. A comparison of the effects of conservative treatment and surgical therapy on laryngeal contact granuloma was made in a retrospective review. METHODS: A total of 124 patients with laryngeal contact granuloma were divided into 2 groups according to treatment: simple surgical excision (n = 36) and conservative treatment (n = 84). Additionally, the reflux finding score (RFS) and the reflux symptom index (RSI) were utilized to assess the disease. RESULTS: A total of 124 patients, with a median age of 48.5 years, ranging from 9 to 74 years, were recruited (107 male, 17 female). According to the diagnostic criteria for laryngeal reflux (RSI >13 or RFS >7), there were 67 cases, accounting for 54.03% of the total. Surgery was effective in 15 patients (15/36, 41.67%), and conservative treatment was effective in 62 patients (62/84, 73.81%). The 2 groups had statistically significant differences. CONCLUSIONS: Conservative treatment, which is a comprehensive anti-reflux therapy, is better than surgical therapy and plays an important role in the treatment of laryngeal contact granuloma.

Abstract Introduction Laryngeal granulomas are benign, recurrent lesions of many causes (reflux, voice abuse, intubation, and idiopathic), which renders its treatment difficult. Objective To describe our experience in the treatment of laryngeal granulomas. Methods From 16 medical records of the patients with laryngeal granulomas seen between 2010 and 2017 in a university hospital, the following data were analyzed: age, gender, vocal and gastroesophageal symptoms, vocal overuse, intubation, treatments, videolaryngoscopy before and after the treatment. Results Gender: female, 10; male, 6. Age: between 20 and 60 years old (11%). Etiology of the granulomas: intubation (9), reflux (4), idiopathic (3). The initial treatments adopted in all cases were: inhaled beclomethasone dipropionate 100 μg 12/12 hours (1month), proton pump inhibitor, omeprazole 40 mg/day (2months), and dietary and voice education. After this period, 10 patients (7 postintubation, 3 idiopathic) were submitted to surgery, since no improvements in the symptoms or in the lesions were seen. Of these, two recurred, requiring a second surgery, one of which recurred six times and received botulinum toxin A. Only one patient with granulomas due to laryngopharyngeal reflux presented no improvement in the symptoms nor in the lesion after the pharmacological treatment and had been submitted to microsurgery. All of the other patients with reflux granulomas were successfully treated with the drug treatment, and the longest treatment time for complete remission of the symptoms and of the lesions was 9 months. Conclusions In laryngeal granulomas caused by reflux, treatment with inhaled steroids and proton pump inhibitors proved to be effective, although prolonged. In postintubation and idiopathic granulomas, surgery was the best treatment.

Dysphonia is common in pediatrics and affects individuals from infancy through their teenage years. Pediatric dysphonia has a variable impact on children, ranging from no impact to a severe social barrier. Although most etiologies are benign, potentially life-threatening causes must be ruled out by direct examination of the larynx. The most common benign lesions of the larynx in pediatrics are vocal nodules, vocal fold polyps, cysts, granulomas, ectasias, sulcus vocalis, and vascular lesions, including hemangioma and postcricoid cushion. Treatment of benign vocal lesions should be tailored to the individual patient and the perceived impact.

Benign laryngeal lesions are often the result of phonotraumatic forces on the vocal folds and thus classically are treated with a combination of voice therapy and phonomicrosurgical techniques to minimize inadvertent additional trauma. Newer management strategies expand on these techniques with the use of the pKTP laser as well as intralesional injections, both in the operating room and in the awake outpatient setting.

Abstract Introduction: Laryngeal granulomas post intubation are benign but recurrent lesions. There is no consensus for its treatment. Objective: To describe the effectiveness of different treatment modalities for primary or recurrent laryngeal granulomas resulting from endotracheal intubation. Methods: Systematic review and proportional meta-analysis. Eligibility criteria - experimental or observational studies with at least five subjects. Outcomes studied - granuloma resolution, recurrence, and time for resolution. Databases used - Pubmed, Embase, Lilacs, and Cochrane. The Stats Direct 3.0.121 program was used. Results: Six studies were selected, with 85 patients. The treatments registered were: antireflux therapy, speech therapy, anti-inflammatory drugs, steroids, antibiotics, zinc sulfate and surgery. 85 patients from six studies had primary treatment: surgery ± associations (41 patients), resolution chance 75% (95% CI: 0.3-100%, I 2 = 90%), absolute relapse risk 25% (95% CI: 0.2-71%); medical treatment (44 patients), resolution chance 86% (95% CI: 67-97%); and absolute relapse risk 14% (95% CI: 3-33%). There was no significant difference between groups. Three studies, encompassing 19 patients, analyzed secondary treatment (failure or recurrence after primary treatment); three subjects presented new recurrence. The time needed to resolve the lesions varied from immediate, after surgery, to 23 months, for inhaled steroid. Conclusion: There is no evidence of high quality that proves the efficacy of any treatment for laryngeal granulomas resulting from endotracheal intubation.
Resumo: Introdução: Granulomas laríngeos pós-intubação são lesões laríngeas benignas, porém recorrentes. Não há um consenso na literatura em relação ao seu tratamento. Objetivo: Descrever a eficácia de diferentes modalidades de tratamento para granulomas laríngeos primários ou recorrentes resultantes da intubação endotraqueal. Método: Estudo-revisão sistemática e metanálise proporcional. Critérios de elegibilidade: estudos experimentais ou observacionais com pelo menos cinco indivíduos. Desfechos estudados: resolução do granuloma, recorrência e tempo de resolução. Bases de dados usadas: Pubmed, Embase, Lilacs e Cochrane. Foi usado o software Stats Direct 3.0.121. Resultados: Foram selecionados seis estudos, com 85 pacientes. Os tratamentos registrados foram: terapia antirrefluxo, terapia da voz, medicamentos anti-inflamatórios, esteroides, antibióticos, sulfato de zinco e cirurgia. Receberam tratamento primário 85 pacientes de seis estudos: cirurgia ± associações (41 pacientes), chance de resolução de 75% (IC 95% 0,3% a 100%, I2 = 90%) e risco absoluto de recorrência de 25% (IC 95%: 0,2% a 71%); tratamento clínico (44 pacientes), chance de resolução de 86% (IC 95%: 67% a 97%) e risco absoluto de recorrência de 14% (IC 95%: 3% a 33%). Não houve diferença significante entre os grupos. Três estudos, que abrangeram 19 pacientes, analisaram o tratamento secundário (falha ou recorrência após o tratamento primário); três indivíduos apresentaram nova recorrência. O tempo necessário para resolver as lesões variou de imediato, logo após a cirurgia, até 23 meses, com tratamento com esteroides inalados. Conclusão: Não há evidências de alta qualidade que provem a eficácia de qualquer tratamento para granulomas laríngeos resultantes da intubação endotraqueal.

AIMS: To confirm the efficacy of conservative treatment for laryngeal contact granuloma and identify factors influencing treatment outcome. METHODS: In this prospective study, patients with laryngeal contact granuloma were divided into a group receiving conservative treatment and a group undergoing surgery. Efficacy was assessed by analyzing the complete response after a 48-week follow-up. The association of treatment outcome with clinical factors was then evaluated. RESULTS: In total, 61 patients, 43 in the group receiving conservative treatment and 18 in the group undergoing surgery, were analyzed, and the complete response rate was 72.1% and 38.9%, respectively. Both univariate analysis and multivariate analysis revealed that treatment modality (p1 = 0.015, p2 = 0.043), voice abuse (p1 = 0.010, p2 = 0.010), and the size of the granuloma (p1 = 0.031, p2 = 0.020) were significantly associated with the complete response of laryngeal contact granuloma. Kaplan-Meier curves showed that alcohol consumption (p = 0.031), voice abuse (p < 0.001), and granuloma size (p = 0.025) were significantly related to the complete response of conservative treatment. CONCLUSIONS: This prospective study strengthens the argument for conservative treatment (instead of surgery) as the first choice for laryngeal contact granuloma. The results also suggest that voice abuse, alcohol consumption, and the size of the granuloma may predict treatment outcome.

Laryngeal contact granuloma, also known as vocal cord granuloma, is the non-neoplastic inflammatory granulation tissue occurring in the vocal cord around. The cause is unclear, morbidity and cure rate is low, the recurrence rate is high, leading to a poor clinical treatment. But some symptoms of the sound disorder, pharyngeal foreign body sensation seriously affect the quality of life of patients, increase the psychological burden of patients. With the increasing awareness of the disease, the deepening of the research, there have been different treatment methods. This paper reviews the previous literatures, and summarizes LCG treatment for the status.

Vocal process granulomas are mainly associated with vocal abuse, gastroesophageal reflux disease (GERD), or endotracheal intubation. In the present study, we evaluate the prognostic factors and the usefulness of a grading system in 64 patients with vocal process granulomas. We classified the granuloma which limited the vocal process of the arytenoid cartilage as grade I, and which originated from the vocal process but extended beyond the vocal process of the arytenoid cartilage as grade II, according to the grading system proposed by Wang CP, et al. First, we treated this disease with conservative treatments including a proton pump inhibitor, steroid inhalation, or voice therapy. Surgical treatment was reserved for failures of conservative treatments or when the diagnosis was in doubt. The overall post-surgical recurrence rate was 65.7%, and it was significantly higher in male than female patients, and in younger than older patients. The overall remission rate was 79.7%. A multivariate analysis revealed that Grade II was a significantly poor prognostic factor and the patients with BMI ≥23 or Age <60 had a tendency to have a poor remission rate. The grading system is useful for anticipating the prognosis in cases of vocal process granuloma.

OBJECTIVE: To explore the clinical features and treatments of contact granuloma of larynx. METHOD: To find the best treatments by analyzing the clinical features, related causes and the treatments of the 13 contact granuloma of larynx cases, which have complete data, of our department from Jan 2005 to Dec 2012, also by comparing the effect of conservative treatment and operation treatment. RESULT: Contact granuloma of larynx is more common in men (84.6%). The main causes are gastro esophageal reflux, chronic cough, habitual hawk and endotracheal intubation disease. However, a big part (38.4%) gets the disease without any other disease history. The main clinical feature of the disease includes: sensation of foreign matter in throat, easy to get exhausted when talking and voice hoarse, but also 30.7% without any feature in throat. Among the 13 cases, 6 were treated by operation and the first recurrence was 66.6%. The cure rate was 50% after one or two operations. The other 7 were treated in conservative way, including anti- Gastro esophageal reflux, avoiding excessive talking, reducing habitual hawk ,or without any medical treatment. The cure rate was 57.1%. The total cure rate was 53.8%. However, it is nonsense to comparing the two different treatments (Chi2 = 0.066, P > 0.05). CONCLUSION: There is still no standard treatment for contact granuloma of larynx and the effect is not good enough. The treatment should be depending on individual case. Conservative treatment is the first choice. However, operation should be considered if the patient has obviously hoarse and his granuloma is too large to breathe well.

OBJECTIVES: Vocal process granulomas (VPGs) are benign laryngeal lesions with controversial treatment and a tendency to recur. There are several treatment options with unpredictable results, high recurrence rates, and disappointing long-term outcome. The aims of this article are to focus on evidence-based current treatment strategies for primary lesions and recurrences. DATA SOURCES: The data came from a systematic review of the literature. METHODS: Main outcome measures were recurrence rate, reduction, and/or complete resolution. Inclusion criteria included English literature, randomized and nonrandomized trials, prospective and retrospective studies, and primary and recurrent cases. Exclusion criteria included case reports, teaching reviews, and papers not focusing on treatment. RESULTS: The time frame of the included studies was from 1997 to 2012. There are 6 different treatment options (single or combined) for VPG. Antireflux medication is the mainstay treatment and when combined with lifestyle changes and voice therapy results in the lowest recurrence rate. "Bloodless" in-office or in-theater laser techniques appear to have lower recurrence rates when compared to traditional cold steel microlaryngoscopy techniques, especially for recurrences. CONCLUSIONS: There is level 2A evidence that antireflux treatment is the main treatment strategy for vocal process granulomas with surgery reserved only for failures of medical treatment or airway obstruction or when diagnosis is in doubt.

BACKGROUND: Intubation of patients with laryngeal granulomas on the vocal folds are sometimes difficult to manage because of potential airway obstruction. Laryngeal granulomas usually have flexible stalks where they attach to the vocal folds. We report a worst-case scenario of dislocation of the laryngeal granuloma during induction of anaesthesia. CASE PRESENTATION: We present a case of laryngeal granulomas on the posterior vocal fold. A 20-year-old woman had an approximately 10-mm tumour in the laryngeal arytenoid region. Manual ventilation resulted in the tumour lodging in the subglottis and the inflated cuff of the intubation tube successfully returned it to its original position during tube withdrawal. Images were obtained using an Airway Scope® (Hoya-Pentax, Tokyo, Japan) and a video laryngoscope. CONCLUSION: In our case, the tumour was benign and relatively small in size; therefore, we did not select tracheotomy as an airway management strategy. The case had a granulomatous tumour arising from the posterior vocal folds on the right side, and the tumour was very flexible. To promptly gain control of the airway in such a case using direct laryngoscopy, thus avoiding tracheotomy, other strategies are suggested, such as bronchoscopic visualization with awake or semi-awake intubation.

The aim of this study was to analyze the outcomes of vocal process granulomas treated with surgery and proton pump inhibitors and to specify related factors of recurrence. The medical records of patients with diagnosis of vocal process granuloma between 2000 and 2012 were reviewed. All patients were treated with surgery and proton pump inhibitors for at least 1 month. Forty-one patients were reviewed; mean follow-up time was 45 months. There was no recurrence among the patients who had a recent history of intubation. The recurrence rates of contact granuloma was 38.7 %, and significantly related to the frequency of surgery (P = 0.042), but was not significantly associated with the history of acid reflux (P = 0.676) and vocal abuse (P = 0.447), lesion size (P = 0.203) or surgical techniques (P = 0.331). Surgery combined with proton pump inhibitors was partially effective for the vocal process granulomas, especially with intubated patients. However, repeat surgery for recurrent contact granuloma should be preceded with caution due to high recurrence rates.

OBJECTIVES/HYPOTHESIS: Vocal process granuloma has been attributed to intubation, laryngopharyngeal reflux, and phonotraumatic/hyperfunctional vocal behaviors. Vocal process granuloma has recurrence rates following surgical excision approaching 92%. We hypothesize that a portion of persistent or idiopathic cases of vocal process granuloma result from underlying glottal insufficiency (GI) caused by paresis, scar, or atrophy. Our goal was to examine our vocal process granuloma population and determine the incidence of GI, treatment interventions, and outcomes. STUDY DESIGN: Retrospective chart review. METHODS: Thirty-four patients with vocal process granuloma were divided into surgically or conservatively managed groups. Patients were identified if they carried a diagnosis of GI. The time to resolution and number of recurrences within the overall treatment period was recorded and compared between subgroups. Pre- and post-treatment Voice Handicap Index-10 (VHI-10) and Reflux Symptom Index (RSI) scores were compared. RESULTS: Eighteen of 34 patients (53%) carried an underlying diagnosis of GI, 13/34 (38%) were treated surgically, and 8/13 (62%) surgical patients had underlying GI. VHI-10 and RSI scores significantly improved after disease resolution (P < .05). CONCLUSIONS: The incidence of GI among patients with vocal process granuloma was 53%. Conservative therapies including treatment of laryngopharyngeal reflux and voice therapy may lead to resolution despite underlying glottal incompetence. If conservative measures fail, recognizing and treating glottal incompetence with true vocal fold augmentation may lead to a shorter surgical treatment course.

The association between superior laryngeal nerve (SLN) paresis and laryngeal granuloma formation has not been described earlier. The aim of this study was to present a series of patients with isolated unilateral SLN paresis who developed contralateral vocal process granulomas. The study design was a retrospective chart review including all patients presenting to Indiana University from February 2006 to August 2007 with laryngeal electromyography (LEMG)-documented unilateral SLN paresis and evidence of laryngeal granuloma on videostroboscopy. Patient history, examination, LEMG findings, and response to treatment were recorded. Three cases of unilateral SLN paresis associated with contralateral vocal process granulomas were identified. In all patients, videostroboscopy examination demonstrated shortening of the ipsilateral vocal fold on adduction and asymmetric contact of the vocal processes at the site of granuloma formation. All patients failed to respond to aggressive antireflux therapy. One patient had spontaneous recovery of the SLN paresis, with subsequent resolution of the granuloma. Two patients were successfully treated with surgical laser excision of the granulomas and injection of botulinum toxin into the normal cricothyroid muscle to alter the vocal process contact points. Vocal process granulomas can be associated with unilateral SLN paresis, potentially related to altered contact points between the vocal processes of the arytenoids.

Vocal process granulomas are benign lesions involved in the healing of posterior glottis injuries. Here, we report the results of our conservative treatment of vocal process granulomas. Fifty-three patients with 54 occurrences of granulomas between 1998 and 2007 were enrolled. All patients were observed without surgical excision or specific medications and regularly monitored with telescopic examinations until the granulomas disappeared. Data on age, sex, clinical presentation, prior history of intubation or gastroesophageal reflux, telescopic findings, management and clinical course were reviewed. There were 41 males and 12 females. The mean ages of granuloma occurrence were 48.1 years in men and 41.6 years in women (p=0.16). Symptoms included hoarseness in 42 patients, cough in 13 patients, lumping sensation in the throat in 15 patients and sore throat in 14 patients. Ten occurrences were stable during the follow-up period, and the other 44 (81%) achieved complete remission (mean period of 30.6 weeks). The remission patterns included progression and remission in 6 occurrences, slow remission in 22 and rapid remission in 16. The remission rate of granulomas was not significantly related to age (p=0.71), sex (p=0.43), prior intubation (p=0.71), acid reflux (p=0.47), unilateral/bilateral lesions (p=1.00) or granuloma size (p=0.46). The remission time was significantly shorter in patients with prior intubation (p=0.04), but not significantly associated with age (p=0.89), sex (p=0.87), acid reflux (p=0.91), unilateral/bilateral lesions (p=0.26) or granuloma size (p=0.96). Long-term observation has demonstrated that vocal process granulomas can be cured at high remission rates without implementing specific treatments.

OBJECTIVE: To study treatment method of laryngeal nonspecific granuloma. METHOD: Twenty-five patients with histopathologically identified laryngeal nonspecific granuloma were retrospective reviewed from 1998-2005. All patients were surgically treated by laser laryngomicrosurgery under general anesthesia, postoperative non-operative therapies included anti-gastroesophageal reflux medication, topical inhalant steroid (Beclometasone, Fluticasone) and voice therapy. Two patients were treated with 12 Gy of low-dose radiotherapy after surgery. RESULT: Laryngeal nonspecific granuloma have remarkable tendency of recurrence despite of surgery and non-surgical managements. Recurrence of laryngeal nonspecific granuloma occurs between 2-3 months postoperatively and requires repeated operation for 3 5 times. For intubation granuloma, 6 out of 8 were healed. Six out of eight contact granulomas were healed. Six of gastroesophageal reflux granulomas were healed. Glottic carcinoma was demonstrated in one case after 2 sessions of combined managements. Two patients were completely healed by low-dose radiotherapy of 12 Gy. CONCLUSION: Laryngeal nonspecific granuloma have an obvious tendency of recurrence, however, surgery is an important therapy. Combined non-surgical therapies (anti-gastroesophageal reflux medication, topical inhalant steroid and voice therapy) are necessary. In case which routine ways fail to control recurrence, low-dose radiotherapy is recommended because of its safety and satisfied effect.
