Objective:This study aims to explore the clinical effectiveness of a novel treatment method for refractory laryngeal contact granuloma, involving CO2 laser excision with local pedicled mucosal flap transfer combined with type A botulinum toxin injection. Methods:A retrospective analysis was conducted on 18 patients with refractory laryngeal contact granuloma who visited Department of Otolaryngology Head and Neck Surgery, Nanjing Tongren Hospital, School of Medicine, Southeast University from January 2021 to June 2023. These patients underwent CO2 laser excision of the granuloma with local pedicled mucosal flap transfer combined with type A botulinum toxin injection. During follow-up, electronic laryngoscopy were performed at 1, 3, 6, and 12 months postoperatively, and local laryngeal mucosa, voice quality, and pharyngeal discomfort symptoms were evaluated. Results:Postoperative electronic laryngoscopy revealed the disappearance of granulomas in all 18 patients. Symptoms such as hoarseness, foreign body sensation in the throat, and cough were significantly improved. No complications were observed systemically or locally. No recurrence was observed during one-year follow-up. Conclusion:CO2 laser excision of granuloma with local pedicled mucosal flap transfer combined with type A botulinum toxin injection could eliminate the lesion, restore the integrity of the vocal fold lining, preserve the perichondrium, and provide a time window for mucosal flap recovery. This approach adheres to the principle of preserving normal mucosa, achieves a high cure rate, and is therefore worthy of widespread promotion and application in clinical practice.

BACKGROUND: Endotracheal intubation can cause focal ischemia, damage or edema to the laryngeal mucosa, and may be followed by serious complications such as vocal cord paralysis, ulcers, and granulation tissue formation. Laryngeal granuloma is rare but also a significant late complication of endotracheal intubation, and anesthesiologists should be concerned about it.CASE: We experienced four cases of laryngeal granuloma that developed after two-jaw surgery January 2017–December 2018 in our hospital and would like to report these cases with brief review of literature.CONCLUSIONS: There are frequent movements on the head and neck in maxillofacial surgery and the nasotracheal intubation should be prolonged after bimaxillary osteotomy surgery because of post-operative airway problems. This may be why two-jaw surgery may have higher occurrence of laryngeal granuloma than others.

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.

Inflammatory pseudotumor is a benign disease entity, which is histologically composed of inflammatory cells and fibrotic stroma. It is mainly found in the respiratory tract, but it has also been reported in the liver, central nervous system, soft tissues, urological system, and gastrointestinal tract. It is extremely rare in the spleen and there have been no cases of splenic inflammatory pseudotumor associated with autoimmune thyroiditis in Korea. The pathogenesis or etiology is unknown, but hypotheses include infection, autoimmunity, and parenchymal necrosis with hemorrhage. Because inflammatory pseudotumor may mimic malignant tumors on radiologic findings, pathologic confirmation is necessary to distinguish it from lymphoproliferative disorders of the spleen and other malignant tumors. We report a case of inflammatory pseudotumor of the spleen associated with autoimmune thyroiditis in a patient who complained of periumbilical pain.

Although many factors associated with difficult intubation have been known, predictors of difficult mask ventilation are not well known. We experienced a case of nearly complete airway obstruction following usual anesthetic induction which needed various emergency treatments. The patient had a preoperative diagnosis of contact granuloma of right posterior vocal cord and bilateral vocal cord palsy but later was found out as invasive laryngeal cancer. Upon the surgical field of view, both vocal cords were showing significantly thickened and fixated appearance and was considered as in the critical narrowing state with the potential of complete obstruction. Using C-MAC® video laryngoscope we were able to see the narrowed vocal cord and choose proper size of endo-tracheal tube. Consequently, intubation was successfully done and operation was conducted. From this case, we have lessons that physicians should examine the patient's airway more carefully in case of laryngeal mass and prepare emergency measures.

The laryngeal granuloma (LG) is non-neoplastic lesion that mainly develops in the posterior vocal folds. It is welknown that mis- or overuse of voice, habitual coughing, and endotracheal intubation can become the cause of LG. The laryngopharyngeal reflux also comes into the spotlight as an etiologic factor. Although LG has a tendency to recur easily, it is not a premalignant lesion. The co-existence with granuloma and laryngeal cancer has not been reported earlier. Recently, we encountered a 72-year-old man with a posterior glottic mass, which was diagnosed as squamous cell carcinoma coexisting with granuloma. To our knowledge, this is a first report on two coexisting carcinomas in the glottis.

OBJECTIVE: To study the efficacy of treatment with microsurgery in combination with local injection of type A botulinum toxin for vocal process granuloma. METHOD: 28 patients with vocal process granuloma received endotracheal intubation under general anesthesia. The lesion was removed with micro-scissor and CO2 laster under a self-retaining laryngoscope and microscope. The incision and mucous membrane surrounding the wound was closed with 8-0 absorbable suture. 4-point injection of botulinum toxin type A 8-15 u was then performed along the thyroarytenoid muscle and arytenoid muscle of the same side. Postoperative medication was administered based on disease causes. RESULT: All patients experienced vocal cord dyskinesia of the injected side 2-3 days after surgery. At 1 month after the surgery, wound healing was good in all the 28 patients, and the vocal cord movement was limited at the injected side. At 3 months, movement of the bilateral vocal cords was normal, and the vocal cord process mucosa was smooth. Patients were followed up for more than a year, and only one patient had recurrence in 2 months after surgery. The cure rate was 96. 4%. CONCLUSION Combination of laryngeal microsurgery and type A botulinum toxin local injection can shorten the treatment course 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.

The causes of dysphonia can be classified into two groups, organic and functional. Functional dysphonia includes spasmodic dysphonia, muscle tension dysphonia, mutational dysphonia and conversion dysphonia, etc. The findings of laryngoscopy in these dysphonia are almost normal. Organic dysphonia is caused by anatomical problems in the larynx, especially on the vocal fold. Benign diseases of the vocal folds are common and mainly presented as voice disorders such as hoarseness, harshness, weakness, or even loss of voice. Benign neoplasm of the larynx are very rare condition except papilloma. The most common symptoms are voice change. However, they can be presented as wheezing, dyspnea, discomfort in the throat, or cervical mass depending on the size and location of the tumor. Detailed history taking and thorough laryngeal endoscopic examination are necessary for the appropriate diagnosis and treatment.
