ABSTRACT
PURPOSE: To examine the factors that affect graft healing after laryngotracheal reconstruction (LTR). METHODS: We conducted a retrospective chart review at King Abdulaziz University Hospital, Riyadh, Saudi Arabia, between January-2008 and October-2023. We included all patients who underwent LTR and required anterior and/or posterior graft placement, while those who underwent procedures without graft placement and those with incomplete information were excluded. RESULTS: Forty-nine patients were analyzed. Most patients were pediatric (65.3%), male (65.3%), had no coexisting comorbidities (55.1%), and harbored grade 3-4 stenosis (59.2%). Thirty patients (61.2%) underwent open surgery. Various graft complications occurred including infection (n = 1, 2%), dehiscence (n = 3, 6.1%), scar (n = 6, 12.2%), and granulation (n = 29, 59.2%). Only 15 patients (30.65%) achieved the composite status of "healthy" graft. Among 43 patients who had postoperative cultures, positive results for Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus were observed in 10 and four patients, respectively. Open surgery and double-stage procedure were significantly associated with higher rates of granulation tissue formation. Pediatric-age group had significantly higher rate of complete epithelization compared to adult-age group. A significantly greater proportion of patients who had unhealthy grafts had open surgery. The rate of double-stage LTR was significantly higher in unhealthy grafts compared to healthy grafts. Prolonged stent duration was linked to various graft-related complications. Multivariate logistic regression analyses showed no statistically significant correlations between various factors and postoperative graft-related complications. CONCLUSION: Open surgery, double-stage procedure, pediatric age group, and stent duration were not significant risk factors associated with postoperative graft-related complications during LTR in multivariate analysis.

BACKGROUND: No studies have been conducted to define the lengths of the upper airway's different segments in normal healthy adults. AIMS/OBJECTIVES: This study aimed to determine the length of the subglottis and extrathoracic trachea and the factors affecting it. MATERIAL AND METHODS: This was an observational retrospective review study. Included 102 adult patients who underwent CT scan during the quiet inspiration phase of the upper airway. RESULTS: The results revealed significant positive linear relationships between height and both anterior and posterior subglottic measurements (p < 0.001). Additionally, a statistically significant, moderately strong negative correlation between age and extrathoracic tracheal measurements (p > 0.001) was observed. Men exhibited longer anterior (p < 0.001) and posterior (p > 0.001) subglottic measurements. In both sexes, the average length of the anterior subglottis was 14.16 (standard deviation [SD]: 2.72) mm, posterior subglottis was 14.51 (SD: 2.85) mm and extrathoracic trachea was 66.37 (SD: 13.71) mm. CONCLUSION AND SIGNIFICANCE: We concluded that a normal healthy adult's anterior subglottis length is 6.3-19.3 mm (mean: 14.16 [SD: 2.72] mm), posterior subglottis length is 6.1-20.0 mm (mean: 14.51 [SD: 2.85] mm) and extrathoracic trachea length is 25.2-98.5 mm (mean: 66.37 [SD: 13.71] mm). Age, height and sex affected the upper airway length.

OBJECTIVES: To study the clinical evaluation of recurrent respiratory papillomatosis (RRP) patients and the factors associated with the improvement in the Derkay's score as a measure of disease severity. METHODS: A retrospective cohort that included all juvenile RRP patients who were admitted to King Abdulaziz University Hospital, Riyadh, Saudi Arabia, between September 2015 and June 2022 and underwent surgical debulking. RESULTS: A total of 16 patients were eligible to join our study. Among them, 7 patients were males. Hoarseness of voice was the most frequent symptom. The median period of the follow-up was 56 months. Complete remission was achieved in 31.3%. The univariate linear regression model revealed that the cidofovir-treated patients had a significant reduction in the change value of Derkay's score compared to those without treatment (regression coefficient= -5.83, 95% confidence interval [CI]: [-11.5 to -0.143], p=0.045). Also, the increased first Derkay's score decreased the change value and subsequently increased the improvement chance of the disease (regression coefficient= -0.424, 95% CI: [-0.764 to -0.083], p=0.018). However, in the multivariate regression model, both variables showed non-significant results. CONCLUSION: cidofovir treatment and higher Derkay's scores affected the disease improvement.

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.
