Abstract
BACKGROUND Laryngocarcinoma (LC) is a common malignant tumor of the head and neck, accounting for 1% to 5% of human tumors. The primary objective of the present study was to evaluate the survival time of patients with LC at different sites. METHODS Information concerning patients with LC was extracted from the Surveillance, Epidemiology, and End Results (SEER) database between 1975 and 2016. RESULTS In total, 16 255 patients with LC were selected from the SEER database. Among all patients, 80.2% were male; males also predominated in each tumor site subgroup. Most of the patients were aged between 60 and 69 years, had white ethnicity, were single, and had American Joint Committee on Cancer (AJCC) stage I cancer with T1, N0, and M0. The present study investigated the role of interventions in all LCs at different AJCC stages. Across the whole population, regardless of the intervention used, survival increased in patients at any cancer site. CONCLUSIONS The study found that male sex, age ≥80 years, black ethnicity, single status, T4, N4, M1, and AJCC stage IV were associated with higher mortality rates at all sites of LC. Aggressive interventions, especially surgery and radiotherapy, may improve survival in patients with LC at different sites and with different AJCC stages.

The accuracy of the ultrasound measured transverse cricoid diameter and the epiphyseal transverse diameter of the distal radius in predicting the pediatric endotracheal tube size. Paediatr Anaesth 2024; 34:68-78. [PMID: 37772473 DOI: 10.1111/pan.14761] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 08/28/2023] [Accepted: 08/31/2023] [Indexed: 09/30/2023]
Abstract
BACKGROUND In everyday pediatric anesthesia practice, clinicians frequently exchange an already inserted endotracheal tube because of a leak or resistance causing significant morbidity. We investigated the accuracy of two ultrasound measurements; the transverse cricoid diameter and epiphyseal diameter of the distal radius in the prediction of endotracheal tube size that best fits in children compared to age-based formulas. PATIENTS One hundred children (1-6 years) who underwent elective surgery with endotracheal tube whether cuffed (n = 50) or uncuffed (n = 50) were enrolled. The primary endpoint was the agreement between the reference tube size for which its outer diameter was selected based on transverse cricoid diameter and the final best-fit-ETT. The Correlation and Bland Altman agreement tests were conducted between best-fit-ETT outer diameter and ultrasound-measured outer diameter, and between best-fit-ETT inner diameter and inner diameter calculated by age-based formulas. RESULTS The agreement rate between transverse cricoid diameter-based endotracheal tube size and best-fit-ETT size was 88% in cuffed group compared to 90% in uncuffed group. A significant positive correlation was reported between the outer diameter of best-fit-ETT and the outer diameter measured by the two ultrasound methods. A lower degree of positive correlation was reported between the inner diameter of best-fit-ETT, and the inner diameter calculated by age-based formulas. Bland Altman's analysis showed agreement between best-fit-ETT outer diameter and epiphyseal diameter of the distal radius in both groups and with transverse cricoid diameter in the cuffed group, with no agreement with age-based formulas in either group. CONCLUSIONS Both transverse cricoid diameter and epiphyseal diameter of the distal radius are reliable predictors of the size of best-fit-ETT pediatric endotracheal tube compared to age-based formulas. To save time and effort, we recommend the US measurement of the epiphyseal diameter of distal radius in the preoperative visit and documenting the predicted tube size with the preoperative assessments.

Myer-Cotton Grade of Subglottic Stenosis Depends on Style of Endotracheal Tube Used. Laryngoscope 2023; 133:2808-2812. [PMID: 36688266 DOI: 10.1002/lary.30577] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 12/14/2022] [Accepted: 01/03/2023] [Indexed: 01/24/2023]
Abstract
OBJECTIVES Determine percentage of subglottic stenosis using current endotracheal tube (ETT) cross-sectional areas as actual, compared with previously published ETT cross-sectional areas as expected, and determine if style of ETT could result in a change in percentage of stenosis or Myer-Cotton grade. STUDY TYPE Cross-sectional study. DESIGN Prospective analysis. METHODS Eight styles of uncuffed pediatric ETT from four manufacturers ranging from 2.0 to 6.0 inner diameter (ID) were evaluated. ID and outer diameter (OD) measurements were obtained from each company's specification sheets. Cross-sectional area was calculated for each ETT using the formula (Area = πr2 ). The cross-sectional areas of each current ETT (actual) were compared with those of previously published ETTs (expected) based on age, and the degree of stenosis was calculated using the formula [1- (Area actual /Area expected )] × 100%. Ranges of percentage for each style of ETT were calculated. RESULTS There was an increase in range of OD and area with increasing size of ETT ID, with the largest range in OD being 0.8 mm, and the largest range in area being 10.55 mm2 . The median interquartile range (IQR), range of percentage stenoses was 11 (5%), ranging from 0% to 21%. Seven of 28 (25%) ranges were found to span two Myer-Cotton grades. CONCLUSIONS The Myer-Cotton grade of subglottic stenosis depends on the style of ETT used. Using updated values from currently available ETTs aims to keep this grading system valid with respect to surgical approach and outcomes following surgery.

Abstract
Pediatric vascular anomalies are classified into vascular malformations and vascular tumors. While vascular malformations are generally anomalous vessels, vascular tumors arise from endothelial cells characterized by abnormal proliferation. Vascular tumors, also called hemangiomas, are subdivided into infantile and congenital hemangiomas. The differentiation of these anomalies can be challenging, and immunohistochemical staining is often employed for this purpose. The GLUT-1 (erythrocyte-type glucose transporter protein) stain is positive for the infantile type. Hemangiomas are usually found in the head and neck region. Their occurrence in the laryngeal region in infants tends to manifest in the subglottic region. Hemangiomas in the larynx mostly do not cause any symptoms until they are large enough to cause dyspnea, stridor, or hoarseness of voice. They are mostly treated in infants with propranolol or surgical excision. We report a case of an eight-day-old female infant who presented with a mass that recurrently protruded out of the mouth when she cried. The mass stopped protruding out of the mouth when the baby became restless, had respiratory distress, and refused feeds. Endoscopy of the pharynx and larynx showed a pedunculated hemorrhagic mass attached by a stalk to the left arytenoid. With cautery, the stalk of the lesion was severed from its attachment. The baby was discharged on the fourth postoperative day and histology reported a cavernous hemangioma. Seven months after the surgery, the baby is growing normally. Yearly follow-up endoscopies have been scheduled to evaluate for recurrence or residual disease.

Abstract
RATIONALE Subglottic tracheal stenosis is stenosis of the trachea between the vocal cords and the lower margin of the cricoid cartilage. The Montgomery T-tube is used as a tracheostomy tube and a combined tracheal stent to avoid postoperative tracheal stenosis. PATIENT CONCERNS Because the stenosis is close to the glottis, surgical treatment is complex, and many complications may arise. DIAGNOSES Subglottic tracheal stenosis. INTERVENTIONS The patients underwent endotracheal intubation or tracheotomy because of acute pancreatitis, laryngeal malignancy, or cerebral hemorrhage after endotracheal intubation or tracheotomy and presented with varying degrees of tracheal stenosis and dyspnea. We relieved airway stenosis and improved dyspnea in these 3 patients by placing a Montgomery T-tube. OUTCOMES None of the 3 patients had intraoperative complications. In 2 of the cases, airway secretions were stored after surgery. LESSONS Montgomery T-tube placement is safe and effective for patients with complex subglottic tracheal stenosis.

Abstract
Foreign body aspiration is rare in children below 6 months of age. Very young children presenting with stridor, atypical croup presentation, and not responding accordingly, subglottic foreign body aspiration should be considered. These may not always be visible with bedside flexible endoscopy and may need investigation under anesthesia. We report two cases of devil's thorn aspiration in young infants. These children were left on the floor to play and devils thorn may be a danger lurking as the they have been deposited unknowingly by the shoes people wear and pick up by these young infants.

Abstract
Inflammatory myofibroblastic tumor (IMT) is a very rare mesenchymal tumor that can behave as a locally benign or aggressive lesion. Here, we present an extremely rare case of IMT involving the subglottic of a middle-aged male. Steroid therapy treatment alleviated dyspnea, but the recurrence of dyspnea was reported two months later. Both sides of the subglottic tumor were excised following treatment, and the surgical specimens were subjected to histopathological evaluation and diagnosis for IMT. At 4 years after excision, follow-up laryngoscopy revealed symmetric vocal cords without evidence of any subglottic mass. Subglottic mass is often asymptomatic until it presents with hoarseness or dyspnea, and subglottic IMT is rare. Based on the successful treatment of our case, complete surgical excision is highly recommended for this rare tumor. However, further research is needed to discover a more effective and cost-effective treatment approach.

Abstract
OBJECTIVES Post-extubation upper airway obstruction is the most common cause of extubation failure in children, but there are few data regarding long-term morbidity. We aim to describe the frequency of long-term airway sequelae in intubated children and determine the association with post-extubation upper airway obstruction. DESIGN Retrospective, post hoc analysis of previously identified prospective cohort of children in the pediatric/cardiothoracic ICU at Children's Hospital Los Angeles from July 2012 to April 2015. A single provider blinded to the upper airway obstruction classification reviewed the electronic medical records of all patients in the parent study, before and after the index extubation (extubation during parent study), to identify pre-index and post-index upper airway disease. Primary outcomes were prevalence of newly diagnosed airway anomalies following index extubation. SETTING Single center, tertiary, 391-bed children's hospital. PATIENTS From the parent study, 327 children younger than 18 years (intubated for at least 12 hr) were included if they received subsequent care (regardless of specialty) after the index extubation. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS New airway anomalies were identified in 40 of 327 children (12.2%). Patients labeled with subglottic upper airway obstruction at the index extubation were more likely to be diagnosed with new airway anomalies on subsequent follow-up, receive long-term Otolaryngology follow-up, or receive airway surgery (all p ≤ 0.006). In multivariable modeling, upper airway obstruction as the primary reason for initial intubation (odds ratio, 3.71; CI, 1.50-9.19), reintubation during the index ICU admission (odds ratio, 4.44; CI, 1.67-11.80), pre-index airway anomaly (odds ratio, 3.31; CI, 1.36-8.01), and post-extubation subglottic upper airway obstruction (odds ratio, 3.50; CI, 1.46-8.34) remained independently associated with the diagnosis of new airway anomalies. CONCLUSIONS Post-extubation subglottic upper airway obstruction is associated with a three-fold greater odds of long-term airway morbidity. These patients may represent an at-risk population that should be monitored closely after leaving the ICU.

Abstract
OBJECTIVES The aim of this article was to describe the surgical technique and report the oncological and functional outcomes of the partial glottic-subglottic laryngectomy (GSL). METHODS A retrospective review of the clinical charts of patients who underwent GSL for laryngeal cancer from 1989 to 2020 at the Otolaryngology Unit of the Vittorio Veneto Hospital, a referral center for laryngeal cancer treatment. RESULTS The present article considered 36 patients who were submitted to GSL for laryngeal cancer. The pathological exam found squamous cell carcinoma (SCC) in 16 cases, adenoid-cystic carcinoma (ACC) in 9 cases, laryngeal chondrosarcoma in 8 cases, 1 giant cell carcinoma, 1 carcinosarcoma, and 1 metastasis of colon adenocarcinoma. Considering the 16 SCC cases we observed a recurrence rate of 31%, the overall survival (OS) and disease-specific survival (DSS) were 75%. The 9 ACC cases had a recurrence rate of 23% and OS/DSS of 88%. In the 8 chondrosarcomas no relapses were reported and the OS/DSS were 100%. Among the patients without recurrence of the disease, a definitive decannulation was achieved in 21 cases (75%). CONCLUSIONS The GSL represents a valid alternative to total laryngectomy in selected cases of laryngeal cancer involving the glottic and subglottic regions.

Abstract
OBJECTIVE Single-stage laryngotracheal reconstruction (SSLTR) provides a definite surgical treatment for patients with complex glotto-subglottic stenosis. To date, the influence of SSLTR on the functional outcome after surgery has not been analyzed. METHODS A retrospective analysis of all patients receiving a SSLTR between November 2012 and October 2019 was performed. Preoperatively and 3 months postoperatively, patients received a full functional evaluation, including spirometry; voice measurements (eg, fundamental frequency; dynamic range, singing voice range, and perceptual voice evaluation using the Roughness-Breathiness-Hoarseness [RBH] score, and fiberoptic endoscopic evaluation of swallowing [FEES]). RESULTS A total of 15 patients with a mean age of 45 ± 17 years underwent SSTLR. Two (13%) patients were men and 13 (87%) were women. The majority of patients (67%) had undergone previous surgical or endoscopic treatment attempts that had failed. At the 3-month follow-up visit, none of the patients had signs of penetration or aspiration in their swallowing examination. Voice measurements revealed a significantly lower fundamental voice frequency (201.0 Hz vs 155.5 Hz; P = .006), whereas voice range (19.1 semitones vs 14.9 semitones; P = .200) and dynamic range (52.5 dB vs 53.0 dB; P = .777) was hardly affected. The median RBH score changed from R1 B0 H1 to R2 B1 H2. In spirometry, breathing capacity increased significantly (peak expiratory flow, 44% vs 87% [P < .001] and mean expiratory flow at 75% of vital capacity, 48% vs 90% [P < .001]). During a median follow-up of 32.5 months (range, 7-88 months), none of the patients developed re-stenosis. CONCLUSIONS For complex glotto-subglottic stenoses, durable long-term airway patency together with reasonable voice quality and normal deglutition can be achieved by SSLTR.

Abstract
OBJECTIVES/HYPOTHESIS Subglottic squamous cell carcinoma (SSCC) is a rare cancer with limited evidence-based treatment guidelines. This study aimed to describe the treatment patterns for SSCC and to determine which treatments provide the best overall survival. STUDY DESIGN Retrospective database review. METHODS The National Cancer Database (NCDB) was queried for patients treated for SSCC from 2004 through 2014. Overall survival (OS) rates were determined by the Kaplan-Meier method. Clinicopathologic characteristics were assessed by univariable and multivariable Cox proportional hazards models, which corrected for age, sex, race, insurance status, income quartile, residence, Charlson-Deyo comorbidity score, facility type providing treatment, tumor grade, and clinical N and T category. RESULTS In this cohort of 549 patients with SSCC, the 5-year OS was 48.2%. SSCC presented at an advanced stage (American Joint Committee on Cancer stage III or IV) in 60.1% of cases; 78.3% of cases had no nodal metastases. Among only stage IV cases, multivariable analysis showed that radiotherapy (RT) (hazard ratio [HR] = 5.944; 95% confidence interval [CI]: 2.76-12.8; P < .001) and chemoradiotherapy (CRT) (HR = 2.321; 95% CI: 1.36-3.97; P = .002) were both associated with decreased 5-year OS compared to a group consisting of all surgeries. When this analysis was repeated for only stage III cases, RT (HR = 1.134; 95% CI: 0.38-3.37; P = .821) and CRT (HR = 1.784; 95% CI: 0.78-4.08; P = .170) were equivalent to surgery. CONCLUSIONS Using the NCDB to study the largest cohort of SSCC with known staging and treatment, primary surgery may provide a better 5-year OS in advanced-stage SSCC.

Abstract
OBJECTIVES/HYPOTHESIS Cricoid fracture is a serious concern for balloon dilatation in airway stenosis. Furthermore, there are no studies examining tracheal rupture in balloon dilatation of stenotic segments. The aim of this study was to evaluate the effect of supramaximal pressures of balloons on the cricoid and tracheal rings. STUDY DESIGN Prospective cadaveric study. METHODS Seven cadaveric laryngotracheal complexes of normal adults with intact cricothyroid membranes were acquired. Noncompliant vascular angioplasty balloons (BARD-VIDA) were used for dilatation. The subglottis and trachea were subjected to supramaximal dilatation pressures graduated to nominal burst pressure (NBP) and, if necessary, rated burst pressure (RBP). Larger-diameter balloons, starting from 18 mm size to 24 mm, were used. Dilatations were maintained for 3 minutes. RESULTS The cricoid ring was disrupted by larger-diameter balloons (22 mm and 24 mm) even at lower pressures (less than NBP) in six cases. Tracheal cartilages were very distensible, and external examination after supramaximal dilatation (24 mm close to RBP) revealed no obvious cartilage fractures or trachealis tears. Histopathological examination revealed sloughing of mucosa in the areas corresponding to balloon placement, but no microfractures or disruption of the perichondrium of tracheal ring cartilages. CONCLUSIONS These results indicate that the cricoid is vulnerable to injury from larger balloons even at lower dilatation pressures. The tracheal cartilages and the membranous wall of the trachea remained resilient to supramaximal dilatation and larger balloons. LEVEL OF EVIDENCE NA. Laryngoscope, 128:1304-1309, 2018.

Abstract
OBJECTIVE Subglottic squamous cell carcinoma (SCCa) is a rare malignancy representing <5% of all laryngeal cancers. Patients often present with late-stage disease, and survival outcomes are reportedly worse than those for SCCa in other regions of the larynx. STUDY DESIGN Analysis of a population-based tumor registry. SETTING Academic medical center. SUBJECTS AND METHODS The US National Cancer Institute's Surveillance, Epidemiology, and End Results database was queried for cases of subglottic SCCa from 1973 to 2011 (889 cases). Resulting data were analyzed, including patient demographics, therapeutic measures, and survival outcomes. RESULTS Subglottic SCCa most frequently occurred in the fifth to seventh decade of life, with a mean age at diagnosis of 65.7 ± 11.3 years. There was a strong male predilection, with a male:female ratio of 3.83:1. Most patients were stage III and IV (64.4%) per the American Joint Committee on Cancer. The most common treatment modality was a combination of radiotherapy and surgery (38.8%), followed by radiotherapy alone (33.9%), and surgery alone (17.0%). Overall 5-year disease-specific survival rate was 53.7%. When stratified by treatment modality, 5-year disease-specific survival was 62.4% for surgery alone, 56.7% for radiotherapy alone, and 55.1% for surgery with adjuvant radiotherapy (P = .3892). CONCLUSION This study represents the largest cohort of subglottic SCCa. It shows a strong predilection for men in the US population. Surgery with adjuvant radiotherapy was the most commonly employed treatment modality. No statistically significant differences were observed in 5-year DSS by treatment modality.

Abstract
OBJECTIVES/HYPOTHESIS Laryngotracheal stenosis (LTS) is largely considered a structural entity, defined on anatomic terms (i.e., percent stenosis, distance from vocal folds, overall length). This has significant implications for identifying at-risk populations, devising systems-based preventive strategies, and promoting patient-centered treatment. The present study was undertaken to test the hypothesis that LTS is heterogeneous with regard to etiology, natural history, and clinical outcome. STUDY DESIGN Retrospective cohort study of consecutive adult tracheal stenosis patients from 1998 to 2013. METHODS Subjects diagnosed with laryngotracheal stenosis (ICD-9: 478.74, 519.19) between January 1, 1998, and January 1, 2013, were identified. Patient characteristics (age, gender, race, follow-up duration) and comorbidities were extracted. Records were reviewed for etiology of stenosis, treatment approach, and surgical dates. Stenosis morphology was derived from intraoperative measurements. The presence of tracheostomy at last follow-up was recorded. RESULTS One hundred and fifty patients met inclusion criteria. A total of 54.7% had an iatrogenic etiology, followed by idiopathic (18.5%), autoimmune (18.5%), and traumatic (8%). Tracheostomy dependence differed based on etiology (P < 0.001). Significantly more patients with iatrogenic (66%) and autoimmune (54%) etiologies remained tracheostomy-dependent compared to traumatic (33%) or idiopathic (0%) groups. On multivariate regression analysis, each additional point on Charlson Comorbidity Index was associated with a 67% increased odds of tracheostomy dependence (odds ratio 1.67; 95% confidence interval 1.04-2.69; P = 0.04). CONCLUSIONS Laryngotracheal stenosis is not a homogeneous clinical entity. It has multiple distinct etiologies that demonstrate disparate rates of long-term tracheostomy dependence. Understanding the mechanism of injury and contribution of comorbid illnesses is critical to systems-based preventive strategies and patient-centered treatment. LEVEL OF EVIDENCE 4.

Abstract
“PHACES” is a neurocutaneous syndrome that refers to the following associations: Posterior fossa malformations, Hemangiomas, Arterial malformations, Coarctation of the aorta/Cardiac defects, Eye abnormalities, and Sternal defects. Herein, we report the association of PHACES syndrome with airway hemangioma, a serious association that should not be overlooked. The findings of such an association presented here are the first to be reported from Saudi Arabia.

Abstract
PURPOSE Wegener's granulomatosis (WG) is a rare multisystem inflammatory disease, which infrequently involves the subglottic area and trachea. Treatment usually involves the use of immunosuppressive agents with corticosteroids. Some patients, however, continue to have symptoms of airway obstruction after clinical remission following the standard therapeutic regimen. OBJECTIVE To investigate laser treatment for subglottic stenosis in five patients suffering from WG. MATERIALS AND METHODS We endoscopically treated 5 patients with subglottic stenosis due to WG and airway obstruction by Nd:YAG and CO2 lasers. One of the patients had preoperative tracheostomy and after treatment was decannulated and could not breathe without dyspnea. Another patient required stenting of the subglottic area. RESULTS All five patients were able to breathe without dyspnea after the treatment. Three patients were treated with an Nd:YAG laser but needed repeated laser treatment every four to six months, whenever they complained of dyspnea. The other two patients were treated with a CO2 laser; one of these patients had preoperative tracheostomy and was treated twice by CO2 laser and decannulated, with no further difficulty in breathing. The follow-up period was 1-5 years. CONCLUSIONS Nd:YAG and CO2 lasers are recommended in the treatment of subglottic stenosis (SS) due to WG, particularly when the stenosis is in continuity or close proximity to the vocal cords.
