[Stridor due to a subglottic hemangioma compressing the trachea]. / L'image du mois. Stridor secondaire à un hémangiome sous-glottique comprimant la trachée.

Subglottic haemangioma can cause stridor in young children, and sometimes be life-threatening. Larynx ultrasound is a useful, non-irradiating screening test, but the diagnosis must be confirmed by bronchial fibroscopy and injected chest CT scan. Nowadays propranolol is the first-line treatment. If treated early, the prognosis is excellent.

L'hémangiome sous-glottique peut être responsable d'un stridor chez le jeune enfant et, parfois, menacer le pronostic vital. L'échographie du larynx est un examen utile et non irradiant pour le dépistage, mais le diagnostic sera confirmé par une fibroscopie bronchique et un scanner thoracique avec injection de produit de contraste. Le traitement en première intention est le propranolol. Lors d'une prise en charge précoce, le pronostic est excellent.

Development of a nomogram for predicting pharyngocutaneous fistula based on skeletal muscle mass and systemic inflammation indices.

BACKGROUND: Laryngeal and hypopharyngeal cancers often require surgical treatment, which can lead to the development of pharyngocutaneous fistula (PCF). Our research aimed to assess the predictive value of skeletal muscle mass (SMM) and systemic inflammation indices for PCF and construct a clinically effective nomogram. METHODS: A nested case-control study of 244 patients matched from 1171 patients with laryngeal or hypopharyngeal cancer was conducted. SMM was measured at the third cervical level based on CT scans. A PCF nomogram was developed based on the univariate and multivariate analyses. RESULTS: Glucose, white blood cell count, platelet-to-lymphocyte ratio, and skeletal muscle index were independent risk factors for PCF. The area under the curve for the PCF nomogram was 0.841 (95% CI 0.786-0.897). The calibration and decision curves indicated that the nomogram was well-calibrated with good clinical utility. CONCLUSIONS: The nomogram we constructed may help clinicians predict PCF risk early in the postoperative period, pending external validation.

Cardiogenic and obstructive shock: primary laryngeal synovial sarcoma with cardiac metastasis.

A man in his 20s with a history of laryngeal synovial sarcoma presented with dyspnoea. Imaging revealed a large right ventricular (RV) mass, which was resected, and histological analysis indicated synovial sarcoma recurrence. Within 1 month of RV mass resection, the tumour progressed with paratracheal metastasis. The lumen was nearly obliterated, and right ventricular outflow tract (RVOT) obstruction led to rapid deterioration with mixed cardiogenic and obstructive shock. We present a rare case of primary laryngeal synovial sarcoma metastasising to the heart.

Comorbidities and Laryngeal Cancer in Patients with Obstructive Sleep Apnea: A Review.

Introductions: The global prevalence of obstructive sleep apnea shows that this disease appears in 1 billion people, with the prevalence exceeding 50% in some countries. Treatment is necessary to minimize negative health impacts. Obstructive sleep apnea (OSA) is defined as a cause of daytime sleepiness, as well as a clinical manifestation of sleep-disordered breathing. In the literature, there are numerous controversial studies regarding the etiology of this condition, but it is universally accepted that reduced activity in the upper airway muscles plays a significant role in its onset. Additionally, OSA has been associated with a series of comorbidities, such as type II diabetes, metabolic syndrome, and cardiovascular and pulmonary conditions, as well as head and neck tumors, especially oropharyngeal and laryngeal tumors. This is a review of the subject of OSA that considers several aspects: an analysis of the comorbidities associated with OSA, the involvement of tumor pathology in the onset of OSA, and the association of OSA with various types of laryngeal cancers. Additionally, it includes an evaluation of postoperative and medical outcomes for patients with OSA and laryngeal tumors treated surgically and medically, including chemotherapy. Relevant Sections: By taking into consideration the stated objective, a systematic analysis of the available literature was conducted, encompassing the PubMed, Medline, and Scopus databases. The evaluation was based on several keywords, including head and neck cancer, diabetes, diabetic, overlap syndrome, cardiovascular conditions, laryngeal neoplasm, radiotherapy, and chemotherapy, as well as the concept of quality of life in laryngectomized patients and patients with OSA. Discussions: The review evaluates the involvement of OSA in the presence of comorbidities, as well as the increased incidence of OSA in patients with laryngeal cancer. It is important to note that surgical and post-surgical treatment can play a significant role in triggering OSA in these patients. Conclusions: The studies regarding the correlations between OSA, comorbidities, and head and neck tumors indicate a significantly increased risk of OSA in association with conditions such as diabetes, metabolic syndrome, cardiovascular diseases, and head and neck tumors, particularly laryngeal tumors. This association has a physio-pathological basis. The various surgical methods followed by radiation and chemotherapy for tumor treatment do not exclude an increased risk of developing OSA after treatment. This significantly influences the quality of life of patients who survive these types of tumors. Future directions: Due to the multiple comorbidities associated with OSA, the extension of polysomnography associated with investigations during sleep, such as drug-induced sleep endoscopy, represents a tendency for the early diagnosis of this pathology, which affects the quality of life of these patients. Patients with head and neck cancer are at high risk of developing obstructive sleep apnea; this is why it is necessary to expand the polysomnographic investigation of these patients after surgical procedures or after radiotherapy and chemotherapy.

Transnasal negative pressure therapy for accelerating healing and improving the prognosis of pharyngocutaneous fistula.

BACKGROUND: Pharyngocutaneous fistula (PCF) is one of the most common complications of total laryngectomy. This study is to investigate the efficacy of a novel platform called transnasal negative pressure therapy (TNPT) in the management of PCF. METHODS: We retrospectively reviewed 47 patients who underwent total laryngectomy between April 2015 and February 2021 and developed PCF in our hospital. We focused on the healing rate, dressing change frequency, and healing time between the TNPT and non-TNPT groups. The 2 years overall survival (OS) was compared through the log-rank test. RESULTS: There were 18 patients in the TNPT group and 29 in the non-TNPT group. There was no significant between-group difference in the healing rate (chi-square test). However, the frequency of dressing changes was significantly lower (p < 0.001) and the healing time was significantly shorter (p = 0.0194) in the TNPT group than in the non-TNPT group. The 2-year OS rate was significantly higher in the TNPT group (p = 0.0473, log-rank test). CONCLUSION: TNPT promoted wound healing after surgery for PCF and improved the 2-year OS rate. This tool is worthy of clinical application and promotion.

Gastrostomy dependence following pharyngolaryngectomy: The effect of preoperative tube insertion.

BACKGROUND: The aim of this study is to investigate the impact of preoperative gastrostomy in patients undergoing pharyngolaryngectomy (PL) on gastrostomy tube dependence at 6 months postoperatively. METHODS: A retrospective review of patients undergoing PL for laryngeal squamous cell carcinoma between 2005 and 2019 was performed. Parameters were collected and analyzed within the multivariate models. RESULTS: Ninety-three patients (82% male, mean age 63.4 [SD 9.4]) were included. Preoperative tube placement and pharyngocutaneous fistula (PCF) were associated with an increased likelihood of gastrostomy tube dependence at 6 months (odds ratio 6.43, CI 1.1-38.3, p = 0.041) after adjusting for multiple confounding factors. There was no difference in the incidence of delayed oral feeding, PCF, or hospital stay between the groups. CONCLUSIONS: Preoperative tube and PCF are associated with an increased likelihood of tube dependence at 6 months. Patients for preoperative tube insertion should be carefully selected and early oral feeding reintroduction should be encouraged.

Recurrent laryngeal papillomatosis with pulmonary involvement: case report. / Papilomatosis laringea recurrente con compromiso pulmonar: reporte de caso.

Recurrent respiratory papillomatosis is a neoplastic disease caused by the human papillomavirus and characterized by the growth of exophytic proliferative lesions affecting the mucosa of the respiratory tract. This condition has a bimodal age distribution; the juvenile form affects those under 20 years of age, is more aggressive and presents multiple papillomatous lesions and high frequency of recurrence, compared to the adult form. Pulmonary involvement is rare and challenging to treat. We present the case of a 13-year-old male with a history of laryngeal papillomatosis since the age of two years. The patient showed respiratory distress and multiple stenosing nodules in the larynx and trachea, as well as several pulmonary cysts identified on chest CT. The patient underwent excision of the papillomatous lesions and tracheostomy. Then, the patient received a single dose of intravenous bevacizumab 400 mg and respiratory therapies with favorable evolution, without recurrences during follow-up.

La papilomatosis respiratoria recurrente es una enfermedad neoplásica causada por el virus del papiloma humano y caracterizada por el crecimiento de lesiones proliferativas exofíticas que afectan la mucosa de las vías respiratorias. En su epidemiología se presenta una distribución bimodal, con una forma juvenil en menores de 20 años, más agresiva, con múltiples lesiones papilomatosas y alta frecuencia de recurrencia, en comparación con la forma adulta. El compromiso pulmonar es poco frecuente y su manejo es un desafío. Se presenta el caso de un varón de 13 años con antecedente de papilomatosis laríngea desde los dos años. El paciente mostró dificultad respiratoria y múltiples nódulos estenosantes en laringe y tráquea, y varios quistes pulmonares visualizados en la tomografía de tórax. Se le realizó exéresis de las lesiones papilomatosas y traqueostomía. Recibió dosis única de bevacizumab 400 mg intravenoso y terapias respiratorias con evolución favorable, sin recurrencias en el seguimiento.

Effect of possible risk factors for pharyngocutaneous fistula after total laryngectomy of laryngeal carcinomas and surgical wound infection: A meta-analysis.

A meta-analysis study to assess the effect of possible risk factors for pharyngocutaneous fistula (PCF) after total laryngectomy of laryngeal carcinoma. A comprehensive literature examination till January 2023 was implemented and 1794 linked studies were appraised. The picked studies contained 3140 subjects with total laryngectomy of laryngeal carcinomas in the picked studies' baseline, 760 of them were PCF, and 2380 were no PCF. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to calculate the consequence of possible risk factors for PCF after total laryngectomy of laryngeal carcinomas and surgical wound infection after total laryngectomy of laryngeal carcinoma by the dichotomous and continuous styles and a fixed or random model. The PCF had a significantly higher surgical wound infection (OR, 6.34; 95% CI, 1.89-21.27, P = .003) compared with the no PCF in total laryngectomy of laryngeal carcinomas. The smoking (OR, 1.73; 95% CI, 1.15-2.61, P = .008), and preoperative radiation (OR, 1.90; 95% CI, 1.37-2.65, P < .001) had significantly higher PCF as a risk factor in total laryngectomy of laryngeal carcinomas. The preoperative radiation had a significantly lower spontaneous PCF closure (OR, 0.33; 95% CI, 0.14-0.79, P = .01) compared with the no preoperative radiation in total laryngectomy of laryngeal carcinomas. However, the neck dissection (OR, 1.34; 95% CI, 0.75-2.38, P = .32), and alcohol intake (OR, 1.95; 95% CI, 0.76-5.05, P = .17), had no significant effect on PCF in total laryngectomy of the PCF had a significantly higher surgical wound infection, and preoperative radiation had a significantly lower spontaneous PCF closure in total laryngectomy of laryngeal carcinomas. Smoking and preoperative radiation were shown to be risk factors for PCF, however, neck dissection and alcohol intake were not shown to be risk factors for PCF in total laryngectomy of laryngeal carcinomas. Although precautions should be taken when commerce with the consequences because some of the picked studies for this meta-analysis was with low sample sizes.

Effect of obesity on outcomes after open laryngeal surgery including total laryngectomy: A NSQIP database analysis.

BACKGROUND: The impact of obesity on outcomes after open laryngeal surgery has not been well-described. METHODS: The NSQIP database was queried for all open laryngeal surgeries including total laryngectomies between 2005 and 2018. Outcomes of patients identified as obese or nonobese by BMI were compared. RESULTS: Of 1865 patients, 20.1% classified as obese. The most common operation performed was total laryngectomy with or without radical neck dissection (73.2%). Operation time and length of hospital stay were significantly less for obese patients. On multivariate analysis, obesity was associated with less bleeding transfusions occurrences (aOR, 0.395, p = 0.0052), surgical complications (aOR, 0.604, p < 0.001), and any complication (aOR, 0.730, p = 0.0019). CONCLUSION: Though there may be an inverse association of obesity with complications and bleeding transfusion occurrences, as well as decreased operation time and length of hospital stay, several confounders and bias may exist; therefore, it is difficult to conclude that the obesity paradox is present.

Endoscopic observation of pharyngeal mucosal suture healing process after total laryngectomy: case series.

BACKGROUND: Pharyngocutaneous fistula (PCF), a major complication of total laryngectomy, is caused by pharyngeal repair failure. OBJECTIVE: Assess the usefulness of endoscopic observation of the pharyngeal suture's healing process for the early detection of PCF development. METHODS: Pharyngeal mucosal sutures were endoscopically observed postoperatively in patients who underwent total laryngectomy with primary closure. RESULTS: Postoperatively, a white coat adhered to the pharyngeal mucosal suture of all patients. In most cases, the white coat gradually receded, which was considered to be a normal healing process. Thickening of the white coat and/or dehiscence of surgical wound were interpreted as 'poor healing conditions'. Three cases were judged to have developed poor healing conditions of the pharyngeal mucosal suture and one patient developed PCF. The other two patients did not develop PCF, possibly due to early detection of 'poor healing condition' and conservative approach, such as discontinuation of oral intake. CONCLUSIONS: Postoperative poor healing conditions of the pharyngeal mucosal suture may be precursors to PCF development. Endoscopic observation enables early detection of these conditions and may enable the prevention of PCF.

Emergency treatment of airway obstruction caused by a laryngeal neuroendocrine tumor: A case report.

RATIONALE: Laryngeal obstruction is a life-threatening adverse event that requires urgent and appropriate management, particularly in patients with coexisting cardiopulmonary and brain comorbidities. However, laryngeal obstruction caused by laryngeal neuroendocrine tumors has rarely been reported. PATIENT CONCERNS: Neuroendocrine tumors can cause pathological changes in the neuro-humoral system, and asphyxia caused by airway obstruction has a more adverse effect on patients with neuroendocrine tumors. DIAGNOSES: We report the case of a 64-year-old man with clinical manifestations of dyspnea. Preoperative and intraoperative pathological examination indicated that the patient was diagnosed with life-threatening airway obstruction caused by a laryngeal neuroendocrine tumor, pneumonia, and scoliosis. INTERVENTIONS: The patient underwent laryngeal tumor resection under general anesthesia. He was recovered well and was generally good without the necessity of undergoing radiotherapy and chemotherapy at the 6-months follow-up. OUTCOMES: This case report has provided an emergency treatment strategy associated with awake intubation. We concluded that flexible establishment of an artificial airway, skilled anesthesia and surgical manipulation, and necessary postoperative intensive care are extremely important for improving the prognosis of patients with severely difficult airway. It is noteworthy that the timely adjust for endotracheal intubation strategy according to the patient's response is needed. It is important for the long-term prognosis of patients to avoid the establishment of a traumatic artificial airway and the occurrence of adverse complications. LESSONS: 1. Introduction; 2. Case presentation; 3. Discussion; 4. Conclusion.

[Mediastinal emphysema caused by tracheal tube replacement during the operation of laryngeal cancer complicated with tracheal diverticulum: a case report].

The incidence of the tracheal diverticulum is low, and its risk to surgery and anesthesia has not been emphasized. This article reports a case of laryngeal cancer complicated with tracheal diverticulum, which was successfully rescued after mediastinal emphysema caused by the intraoperative replacement of a tracheal catheter. Operations such as anesthesia intubation may lead to severe complications such as pneumothorax due to diverticulum rupture, and the surgical team should pay more attention to the tracheal diverticulum.

Relationship between dysphagia and surgical treatment for supraglottic laryngeal carcinoma: A meta-analysis.

OBJECTIVE: To systematically evaluate differences in swallowing disorder-related manifestations in patients with supraglottic laryngeal cancer, who underwent traditional open partial horizontal laryngectomy (OPHL) and endoscopic supraglottic laryngectomy (ESL). METHODS: A systematic review of the literature and a meta-analysis were performed. The CNKI, Wan Fang, PubMed, EMBASE, Cochrane Library, Web of Science, and Clinical Trials databases for clinical studies data sources were investigated. The efficiency of recovery, postoperative swallowing function, and complications related to dysphagia were investigated to compare the effects of surgical procedures. RESULTS: The meta-analysis included 8 studies with 281 patients. ESL surgery played a positive role in the recovery of patients. Preservation of the anterior epiglottic space, ventricular band, and arytenoid cartilage without destroying the external framework of the larynx can effectively reduce the risk of aspiration pneumonia in patients. CONCLUSIONS: ESL has advantages in postoperative recovery and retention of swallowing function in patients with supraglottic laryngeal cancer.

Delayed Pharyngocutaneous Fistula After Total Laryngectomy Caused by an Anterior Cervical Spine plate.

Pharyngocutaneous fistula (PCF) caused by a previous anterior cervical spine fixation plate more than a decade ago has not been reported yet. A 70-year-old man with dysphagia was diagnosed as supraglottic cancer. After partial laryngectomy and concurrent chemoradiation, due to increasing arytenoid lesion, total laryngectomy was followed. Pharyngocutaneous fistula occurred but resolved spontaneously. However, retropharyngeal granulation tissue emerging from the anterior cervical spine fixation plate caused delayed PCF. Dysphagia and PCF resolved after fixation plate removal.

Convulsive Syncope From Carotid Sinus Syndrome as a Manifestation of Laryngeal Cancer.

OBJECTIVE: Carotid sinus syndrome (CSS) is a rare yet serious presentation of head and neck malignancy. To our knowledge, syncope and seizure-like episodes as a manifestation of carotid sinus syndrome secondary to laryngeal cancer has not been reported to date. We report a case of laryngeal cancer causing convulsive syncope masquerading as seizures due to CSS. METHODS: Case report. The patient's medical record was reviewed for demographic and clinical information. RESULTS: A 62-year-old male presented with multiple episodes of syncope and hoarseness of voice. On nasoendoscopic examination, left vocal cord palsy and left aryepiglottic fold tumor were visualized. Computerized tomography (CT) neck showed a large 2.4 × 3.6 cm left supraglottic tumor with local invasion and extensive cervical lymphadenopathy compressing the carotid sinus. CT guided biopsy of the tumor revealed invasive squamous cell carcinoma. While undergoing evaluation, the patient developed seizure-like episodes. Inpatient telemetry monitoring revealed significant bradycardia and hypotension during these episodes. A permanent pacemaker was inserted which resulted in resolution of the syncopal and seizure-like episodes. CONCLUSION: In patients with unexplained syncope or seizure-like episodes and a background of head and neck cancer, clinicians should consider the diagnosis of CSS. CSS is a poor prognostic factor due to the associated higher stage of disease.

Central-part laryngectomy after laryngotracheal separation to manage pharyngocutaneous fistula: A case report and retrospective analysis of 12 cases.

A 15-year-old girl presented with a 3-year-history of continuous outflow of saliva from a pharyngocutaneous fistula, located at 5 mm superior to her tracheal stoma. She was diagnosed with Miller-Dieker syndrome at birth. At 2 years of age, pediatric surgeons at our institution carried out laryngotracheal separation to prevent aspiration pneumonia. At the age of 12 years, she developed continuous saliva discharge from the fistula. We performed central-part laryngectomy and resection of the pharyngocutaneous fistula, which relieved her from the continuous saliva discharge. Central-part laryngectomy is less invasive and easier to perform than total laryngectomy. We hereby present a case and retrospective analysis of 12 patients, who underwent central-part laryngectomy.

Primary injection laryngoplasty after chordectomy for small glottic carcinomas.

OBJECTIVES: The purpose of this study was to analyze the short- and middle-term effects of primary injection laryngoplasty in patients having tumor resection within the same surgery concerning the vocal outcome. Injection laryngoplasty was performed after harvesting autologous adipose tissue via lipoaspiration. METHODS: A prospective study was performed with 16 patients (2 female; 14 male) who received tumor resection and an injection laryngoplasty using autologous adipose tissue during a single stage procedure. Multidimensional voice evaluation including videostroboscopy, patient self-assessment, voice perception, aerodynamics, and acoustic parameters was performed preoperatively, as well as 1.5, 3 and 6 months postoperatively. RESULTS: Results show an improvement in the roughness-breathiness-hoarseness (RBH) scale, voice dynamics and subjective voice perception 6 months postoperatively. Maintenance of Voice Handycap Index, jitter and shimmer could be observed 6 months postoperatively. There was no deterioration in RBH and subjective voice perception 2 and 6 weeks postoperatively. No complications occurred in the fat harvesting site. CONCLUSIONS: Using the lipoaspiration and centrifugation approach, primary fat injection laryngoplasty shows short-term maintenance und middle-term improvement in voice quality in patients with vocal fold defect immediately after chordectomy 6 months postoperatively. Cancer recurrence rate is comparable to the reported cancer recurrence rate for laryngeal carcinoma and thus not elevated through primary augmentation.

Evaluation of Optimal Assessment Schedules for Surveillance After Definitive Locoregional Treatment of Locally Advanced Head and Neck Cancer: A Retrospective Cohort Study With Parametric Modeling of Event-Free Survival.

Importance: In clinical practice, assessment schedules are often arbitrarily determined after definitive treatment of head and neck cancer (HNC), producing heterogeneous and inconsistent surveillance plans. Objective: To establish an optimal assessment schedule for patients with definitively treated locally advanced HNC, stratified by the primary subsite and HPV status, using a parametric model of standardized event-free survival curves. Design, Setting, and Participants: This was a retrospective study including 2 tertiary referral hospitals and a total of 673 patients with definitive locoregional treatment of locally advanced HNC (227 patients with nasopharyngeal cancer [NPC]; 237 patients with human papillomavirus-positive oropharyngeal cancer [HPV+ OPC]; 47 patients with HPV-negative [HPV-] OPC; 65 patients with hypopharyngeal cancer [HPC]; and 97 patients with laryngeal cancer [LC]). Patients had received primary treatment in 2008 through 2019. The median (range) follow-up duration was 57.8 (6.4-158.1) months. Data analyses were performed from April to October 2021. Main Outcomes and Measures: Tumor recurrence and secondary malignant neoplasms. Event-free survival was defined as the period from the end of treatment to occurrence of any event. Event-free survival curves were estimated using a piecewise exponential model and divided into 3 phases of regular follow-up. A 5% event rate criterion determined optimal follow-up time point and interval. Results: The median (range) age of the 673 patients at HNC diagnosis was 58 (15-83) years; 555 (82.5%) were men; race and ethnicity were not considered. The event rates of NPC, HPV+ OPC, HPV- OPC, HPC, and LC were 18.9% (43 of 227), 14.8% (35 of 237), 36.2% (17 of 47), 44.6% (29 of 65), and 30.9% (30 of 97), respectively. Parametric modeling demonstrated optimal follow-up intervals for HPC, LC, and NPC, respectively, every 2.1, 3.2, and 6.1 months; 3.7, 5.6, and 10.8 months; and 9.1, 13.8, and 26.5 months until 16.5, 16.5 to 25.0, and 25.0 to 99.0 months posttreatment (open follow-up thereafter). For HPV- OPC, assessment was recommended every 2.7, 4.8, and 11.8 months until 16.5, 16.5 to 25.0, and 25 to 99 months posttreatment, respectively. In contrast, HPV+ OPC optimal intervals were every 7.7, 13.7, and 33.7 months until 16.5, 16.5 to 25.0, and 25 to 99 months posttreatment, respectively. Five, 4, 12, 15, and 10 follow-up visits were recommended for NPC, HPV+ OPC, HPV- OPC, HPC, and LC, respectively. Conclusions and Relevance: This retrospective cohort study using parametric modeling suggests that the HNC assessment schedules should be patient tailored and evidence based to consider primary subsites and HPV status. Given limited health care resources and rising detection rates and costs of HNC, the guidelines offered by these findings could benefit patients and health systems and aid in developing future consensus guidelines.
