Correlation of airway ultrasonography and laryngoscopy findings in adults with subglottic stenosis: a pilot study.

PURPOSE: Ultrasonography of the airway has potential as an alternative, non-invasive, method to monitor patients with subglottic stenosis in an outpatient setting. This prospective, interventional, double-blinded study aimed to correlate ultrasound-based and laryngoscopy-based subglottic stenosis assessment in adults. METHODS: The study was conducted between July 2020 and March 2021 at a tertiary referral center. Consecutive adult patients with subglottic stenosis were evaluated using airway ultrasonography 1 day prior to scheduled laryngoscopy. The radiologist was blinded to the preoperative endoscopic findings, and the primary surgeon was blinded to the ultrasonographic measurements. The intraoperative subglottic diameter was defined as the outer diameter of an endotracheal tube passing through the subglottis without producing an air leak. RESULTS: Sixteen patients (11 females; age range, 17-66 years; mean = 44.06, SD = 12.79) were included. The ultrasonographic subglottic diameter ranged from 5.20 mm to 8.00 mm (mean = 6.24 mm, SD = 0.90). In 15 of 16 patients, the diameter difference between the ultrasonographic and intraoperative measurements ranged from -0.80 mm to 0.30 mm (mean = -0.20 mm, SD = 0.35). However, patient 6 had a difference of - 2.10 mm between the two measurements, which was attributed to thick laryngotracheal secretions interfering with the ultrasonographic air shadow. Data analysis of all 16 patients showed a statistically significant correlation between the readings obtained by the two techniques (r = 0.84, P = 0.000051). CONCLUSION: This study found a significant correlation between ultrasonography-based and laryngoscopy-based subglottic stenosis assessment in adult patients. It provides a basis for an alternative and potentially reliable method to monitor patients with subglottic stenosis.

Reliability of the Arabic Glasgow benefit inventory after otolaryngology interventions.

We aim to translate the Glasgow benefit inventory (GBI) questionnaire into Arabic language and assess its reliability in scoring the benefit of patients after otolaryngology interventions. This is a pilot study of an ongoing prospective cohort study. The original GBI questionnaire was translated into Arabic language and back-translated into English by two different experts. The questionnaire was given to patients who were asked to fill it themselves. A group of consecutive adult patients were included in the study. Fifty-one patients were included. Reliability using Cronbach's α was higher than 0.70 for total score and the three subscales. Five loading factors explained 72.9% of the variance reached. The mean benefit of the GBI total score was 30.0 ± 36.37. Subscales scores were as follows: 35.21 ± 25.98 for the general health, 25.81 ± 45.98 for the physical benefit and 29.08 ± 34.45 for the social support. The Arabic GBI questionnaire is reliable to evaluate the quality of life after otolaryngology interventions for Arabic speaking population.

A Novel Endoscopic Anterior Cricoid Rib Grafting: A Feasibility Study in An Animal Model.

Objective: The objective of our study was to document the feasibility of a novel endoscopic anterior cricoid split and rib grafting technique in a goat airway model. Study Design: Feasibility pilot animal study. Setting: Animal surgical laboratory at a tertiary hospital and research center. Methods: Three Ardhi goats were utilized. After harvesting and shaping the rib graft, 2 sutures were inserted transversely into the graft. An endoscopic midline anterior cricoid split was performed and extended down through the first tracheal ring, followed by a balloon dilation of the site. Next, the 2 lower and upper graft suture ends were sequentially passed as endo-extra laryngeal sutures and tied on the anterior neck skin. Laryngeal stent was utilized in 1 goat following graft placement. Results: The surgery was successful in all included animals and bronchoscopy performed 7 days after surgery, revealed that the anterior graft was in good position. One goat developed surgical site infection leading to partial graft resorption. Conclusion: This study demonstrated the feasibility of this novel procedure which is potentially useful for patients who are candidates for a single-stage reconstruction. Future studies should investigate the safety and validity of this technique in a model with subglottic stenosis. Level of Evidence: NA.

Endoscopic Anterior Laryngotracheal Reconstruction.

This article introduces a new endoscopic technique for anterior laryngotracheal reconstruction (LTR) using costal rib cartilage grafting in a 2-year-old patient with acquired Grade III subglottic stenosis. The procedure involves an endoscopic incision in the cricoid cartilage's anterior midline and successful outcomes were achieved without complications. The study emphasizes the benefits of this approach, such as reduced hospital stays, shorter operation time, and decreased scarring, but acknowledges the necessity for further human trials to validate its effectiveness in treating different grades of laryngeotracheal stenosis.

Slide tracheoplasty for congenital tracheal stenosis: A systematic review.

INTRODUCTION: Slide tracheoplasty has become the gold standard surgery for congenital tracheal stenosis (CTS). This condition is rare and the surgery can be challenging and is performed by experienced surgeons in tertiary centers. A few reports involving relatively small cohorts have been published. The aim of this review is to evaluate the post-operative mortality and morbidity of pediatric slide tracheoplasty for CTS. METHODS: A systematic literature review was performed according to PRISMA guidelines. The Medline and EMBASE databases were screened using a search strategy defined in collaboration with a librarian. We included articles reporting the post-operative mortality rate of slide tracheoplasties for treatment of CTS in children, when at least 10 patients were included. RESULTS: A total of 932 articles were reviewed, and 15 studies were eligible with a total of 845 patients. The overall post-operative mortality rate was 9.3 %, and most deaths were airway related. The open revision surgery rate after surgery was 2.8 % and the endoscopic revision rate was 27.6 %. DISCUSSION: This study highlights key factors to consider before the surgery and helps anticipate post-operative follow-up considerations for children with CTS. Several factors were identified as predictors of mortality including young age, weight at the time of surgery and association with lung hypoplasia or aplasia. CONCLUSION: Although slide tracheoplasty has gained popularity in recent years due to better outcomes, it remains a major surgery with mortality risk and the need for multidisciplinary management.

International pediatric otolaryngology group (IPOG) consensus on approach to aspiration.

OBJECTIVE: To provide recommendations for a comprehensive management approach for infants and children presenting with symptoms or signs of aspiration. METHODS: Three rounds of surveys were sent to authors from 23 institutions worldwide. The threshold for the critical level of agreement among respondents was set at 80 %. To develop the definition of "intractable aspiration," each author was first asked to define the condition. Second, each author was asked to complete a 5-point Likert scale to specify the level of agreement with the definition derived in the first step. RESULTS: Recommendations by the authors regarding the clinical presentation, diagnostic considerations, and medical and surgical management options for aspiration in children. CONCLUSION: Approach to pediatric aspiration is best achieved by implementing a multidisciplinary approach with a comprehensive investigation strategy and different treatment options.

Role of Otolaryngologists in the Treatment of Patients With Riboflavin Transporter Deficiency: A Case Report.

Riboflavin transporter deficiency (RTD) is a rare genetic disorder that can have detrimental effects on the nervous system, causing progressive neurodegeneration. Here, we report the second case of RTD in Saudi Arabia. An 18-month-old boy presented to the otolaryngology clinic with six weeks history of progressive noisy breathing associated with drooling, choking, and difficulty in swallowing. Progressive regression of the child's motor and communicative abilities was reported as well. Upon examination, the child had biphasic stridor, chest retractions, bilateral facial palsy, and hypotonia. The presence of an aerodigestive foreign body or congenital anomalies was excluded using bronchoscopy and esophagoscopy. Empirical high-dose riboflavin replacement therapy was initiated upon anticipation of diagnosis. Whole exome sequencing revealed a SLC52A3 gene mutation, which confirmed the diagnosis of RTD. After a period of intensive care unit (ICU) admission with endotracheal intubation, the child's general condition improved, and he was weaned off of respiratory support. Tracheostomy was avoided in this patient, as he responded to riboflavin replacement therapy. During the disease course, an audiological assessment revealed severe bilateral sensorineural hearing loss. He was discharged home on gastrostomy feeding owing to the risk of frequent aspiration, and he was regularly followed up by the swallowing team. The early initiation of high-dose riboflavin replacement appears to be of great value. The benefits of cochlear implants in RTD have been reported, but not fully established. This case report will increase awareness in the otolaryngology community about patients with this rare disease who might initially present to the clinic with an otolaryngology-related complaint.

Safety profile and efficacy of high-dose topical mitomycin-C for choanal atresia repair: A prospective cohort study.

OBJECTIVES: To study the effect of dose-adjusted mitomycin-c (MMC) on the recurrence rate of choanal atresia (CA), and the complication rate associated with this concentration. METHODS: This prospective cohort study was conducted between May 2012 and March 2020 at a tertiary referral center. It included patients of all ages who were diagnosed with CA and scheduled to undergo surgical repair. The MMC group received 4.0 mg/mL of topical MMC. Both groups were followed up for the surgical outcomes and complication rates. RESULTS: Twenty-one patients (15 females) underwent 25 CA repair procedures. The mean age was 44.85 months (standard deviation = 72.85). MMC was used in 12 (57.1%) of 21 patients. Revision CA repair was warranted in three of the nine patients who did not receive topical MMC compared to one of the 12 patients who received topical MMC. The MMC group required 1.08 ± 0.29 surgeries (range, 1-2), whereas the non-MMC group required 1.44 ± 0.73 surgeries (range, 1-3). Functional success was achieved in 17 (81%) patients who remained symptom-free until their last follow-up visit. CONCLUSION: High-concentration MMC was considered safe in the pediatric and adult populations. Although high-concentration MMC could reduce the need for revision surgery, further studies are required to determine whether the effect is significant in a larger sample population.

The Reliability of the Arabic Version of the Dyspnea Index Questionnaire for Upper Airway-Related Dyspnea.

Objectives This study aimed to translate the Dyspnea Index (DI) questionnaire into the Arabic language and determine whether this version is valid and reliable for Arabic-speaking patients with upper airway-related dyspnea. Methods A cross-sectional study was conducted at the King Saud University Medical City otolaryngology clinics in Riyadh, Saudi Arabia. The DI questionnaire was translated into Arabic and then back-translated into the English language. Inclusion criteria were preoperative patients presenting to the otolaryngology clinic with upper airway-related dyspnea between November and December 2020. The results of internal consistency and factor analysis among the items were compared to the original DI development results to assess the reliability of the questionnaire. Results Among a total of 57 recruited patients, 50 questionnaires were completed with an 88% response rate. The mean age of the included patients was 38 ±14 years. Women constituted 58% of the patients. The most common diagnosis was subglottic stenosis (72%). Principle component extraction in factor analysis revealed a single underlying factor for all the questions. Factor loading ranged from 0.69 to 0.85. Reliability statistics showed a high value of internal consistency among the items. The mean inter-item correlation was 0.58. Conclusion Based on our findings, the Arabic version of the DI questionnaire is a reliable instrument for evaluating upper airway dyspnea.

Coin retained in the upper esophagus for more than 4 years: A case report and literature review.

Coins are among the most common foreign bodies ingested by children, especially those below 5 years of age. Early endoscopic retrieval of esophageal coins minimizes the risk of serious complications. However, significant morbidity and mortality are reported when coins are retained in the gastrointestinal tract for prolonged periods of time. We report a case in which a coin was retained in the upper esophagus for 4 years and presented a distinctive clinical course. An esophageal coin retained for a prolonged period may place the patient at a risk of complications such as tracheoesophageal fistulas. The management of patients with complicated aerodigestive tract foreign bodies is challenging. To avoid a delayed diagnosis and to improve the patients' safety, the quality of medical care in rural areas should be monitored by implementing continuous educational programs for primary physicians.

Adverse Respiratory Events After Pediatric Endoscopic Airway Surgeries.

OBJECTIVE: Perioperative risk stratification of pediatric patients undergoing airway intervention remains crucial in identifying those at a higher risk of requiring postoperative intensive care unit (ICU) care. Here we determined the likelihood of and possible risk factors for developing perioperative adverse respiratory events (PAREs) requiring ICU care after various pediatric endoscopic airway surgeries (EASs). METHODS: We conducted a retrospective chart review of pediatric patients who were aged <18 years and underwent EAS between 2015 and 2021. Early postoperative adverse events within 24 h of surgery were recorded and analyzed. RESULTS: Overall, 99 patients who underwent EAS were included. The age at the time of the intervention ranged from 8 months to 18 years. Fifty-eight patients, median age was 4.83 years, underwent papilloma debulking with no high likelihood of PARE in this patient subgroup (OR = 0.48; 0.16-1.44). Twenty-five patients, median age was 9.72 years, underwent balloon dilation of laryngotracheal stenosis with no increase in the likelihood of PARE in this patient population (OR = 2.02; 0.65-6.28). Early postoperative respiratory events occurred in 16 patients (16.2%). Most of these events (75%) manifested within 4 h after surgery. In a univariate analysis, intervention at the level of the subglottis or 2 or more laryngeal subsites increased the risk of PARE (OR = 6.57; 1.11-12.52 and OR = 3.73; 1.93-22.34, respectively). In a multivariate analysis, only intervention in the subglottic area maintained its effect (OR = 6.84; 1.82-25.65). CONCLUSION: Respiratory adverse events following pediatric EAS are not uncommon, and the majority are encountered shortly after surgery. Intervention in the subglottic area was an independent predictor of PARE.

Correlation of quality of life with speech and hearing performance after pediatric cochlear implantation.

OBJECTIVES: This study aimed to determine the correlation of the quality of life (QOL) with the Categories of Auditory Performance (CAP) and the Speech Intelligibility Rating (SIR) scales in children after cochlear implantation. METHODS: This cross-sectional study was conducted from November 2018 to February 2020 at the otolaryngology department at a tertiary referral center. Patients aged ≤16 years who had received cochlear implants (CIs) at our center were consecutively included in this study. Parents were asked to complete the Glasgow Children's Benefit Inventory questionnaire, and auditory and speech assessments were performed by the speech therapists at our center. The correlations of Glasgow Children's Benefit Inventory results with the objective data from the CAP and SIR assessment tools were analyzed. RESULTS: Seventy patients were included in this study. The mean age at implantation was 3 years and 9 months. The mean Glasgow Children's Benefit Inventory score was 52.23 (standard deviation = 23.99), indicating a positive benefit in QOL. There was a statistically significant correlation of the QOL questionnaire score with the CAP score (r = 0.40, p = 0.008), but no correlation was found between the QOL questionnaire score and the SIR score. CONCLUSION: We recommend that cochlear implant patients should undergo an evaluation that incorporates auditory, language, and QOL assessment tools to gain a more comprehensive understanding of their progress.

Reliability of the Arabic Glasgow children's benefit inventory.

OBJECTIVES: To translate the Glasgow Children's Benefit Inventory (GCBI) questionnaire into Arabic language and assess its validity and reliability in scoring the benefit of patients after cochlear implantation in children. METHODS: A cross-sectional study for a group of consecutive pediatric patients who underwent cochlear implantation between November 2018 and February 2020. The GCBI original questionnaire was translated into Arabic language and translated back to English by 2 different experts. The patients/parents were asked to complete the questionnaire given to them. RESULTS: Seventy children were included in the study. The age at implantation ranged from 7 months to 13 years with a mean of 3.4 years (SD=2.3 years). The mean GCBI score was 52.2 (SD=24.0) ranging from -6.25 to 100.00.The internal consistency of the questionnaire was high (Cronbach's α=0.9). The 4-factor dimensions explained 55.1% of the variance. CONCLUSION: The GCBI questionnaire (Arabic version) is reliable tool to evaluate retrospectively the quality of life after an intervention in pediatric age for Arabic speaking population.
