This patient suffered from severe subglottic stenosis(grade Ⅳb). During partial cricotracheal resection, we cut through the cricothyroid membrane and the cricoid arch along the line from the lower edge of the thyroid cartilage to 5 mm of the inferior thyroid cartilage corner anteromedially. This can protect the cricothyroid joint, effectively protect the recurrent laryngeal nerve, and also support the airway. Strictly adhere to airway separation, avoid excessive separation of scars, and combine with reasonable postoperative management to achieve a safe extubation.

Objective:To investigate the prognostic impact of different tumor invasion patterns in the surgical treatment of T3 glottic laryngeal cancer. Methods:A retrospective analysis was conducted on the clinical data of 91 patients with T3 glottic laryngeal cancer. Results:Among the 91 patients, 58 cases （63.7%） had anterior invasion and 33 cases （36.3%） had posterior invasion. The posterior invasion was significantly correlated with invasions of the dorsal plate of cricoid cartilage （P<0.001）, arytenoid cartilage （P= 0.001）, and subglottic region（P = 0.001）. There was no statistical difference in survival outcomes between the total laryngectomy group and the partial laryngectomy group. But in the partial laryngectomy group, the 5-year disease-free survival（DFS） of patients with anterior invasive tumors was better than that of patients with posterior invasion tumors （HR: 4.681, 95%CI 1.337-16.393, P=0.016）, and subglottic invasion was associated with worse loco-regional recurrence-free survival（LRRFS）（HR: 3.931, 95%CI 1.054-14.658, P=0.041）. At the same time, we found that involvement of the dorsal plate of cricoid cartilage was an independent risk factor for postoperative laryngeal stenosis in partial laryngectomy patients （HR:11.67, 95%CI 1.89-71.98,P=0.008）. Conclusion:Compared with total laryngectomy, selected partial laryngectomy can also achieve favorable oncological outcomes. Posterior invasion and subglottic extension are independent prognostic factors for recurrence of partial laryngectomy in T3 glottic laryngeal cancer, and the involvement of the dorsal plate of cricoid cartilage is associated with postoperative laryngeal stenosis. The tumor invasion pattern of laryngeal cancer should be further subdivided in order to select a more individualized treatment plan.

Objective: To investigate outcomes of laryngotracheal reconstruction (LTR)with anterior and posterior costal cartilage grafts in severe pediatric subglottic stenosis (SGS) or laryngeal web (LW). Methods: A review of patients with severe subglottic stenosis or laryngeal web between January 2020 and January 2022 was performed. Demographic features including gender, age at diagnosis, age at surgery, etiology, airway support, and other comorbidities were collected preoperatively. Patients were evaluated in surgical site, breathing, swallowing, phonation and complications postoperatively.Descriptive analysis was used in this research. Results: Eight patients were included: six with grade Ⅲ SGS following Cotton-Myer grading scale, and two with type Ⅲ LW following Cohen's classification. All patients underwent LTR with anterior and posterior costal cartilage grafts. Five patients underwent single-stage LTR (ssLTR), and three patients underwent double-stage LTR (dsLTR). Seven out of eight patients were able to successfully extubate or decannulate with normal swallowing function; four patients had mild hoarseness, and three had moderate hoarseness. One patient failed in extubation, and underwent tracheotomy. Conclusions: LTR with anterior and posterior costal cartilage grafts is an effective and safe treatment for severe SGS or LW. Careful preoperative assessment of disease severity and overall medical status will help selection between ssLTR and dsLTR, thereby maximizing patient outcomes for both modalities.

Infants with laryngotracheal anomalies are clinically manifested as stridor or noisy breathing, choking, hoarseness, feeding difficulties, and cyanotic spells, followed by developmental and growth retardation and other health issues; in severe cases, patients may present with severe dyspnea, which is associated with high mortality. A timely diagnosis as well as appropriate strategy for laryngotracheal anomalies is still challenging for pediatric otolaryngologists. This consensus statement, evolved from expert opinion by the members of the Pediatric Otorhinolaryngology Professional Committee of the Pediatrician Branch of the Chinese Medical Doctor Association, provides comprehensive recommendations and standardized guidance for otolaryngologists who manage infants and young children with laryngotracheal anomalies in evaluation and treatment based on symptomatology, physical and laboratory examinations.

Objective: To compare the accuracy of the centerline extracted based on CT 3D reconstruction and conventional CT 3D reconstruction in measuring the length and degree of laryngotracheal stenosis. Methods: A retrospective analysis was performed on 35 patients with laryngotracheal stenosis (including 19 cases without tracheotomy and 16 cases with tracheotomy) treated in the Department of Otorhinolaryngology Head and Neck Surgery of the First Affiliated Hospital of Guangxi Medical University from March 2006 to March 2016, including 20 males and 15 females, whose ages ranged from 1 to 73 years, with a median age of 40.5 years. And CT data of 20 normal subjects were included in the same period, including 10 males and 10 females, whose ages ranged from 20 to 63 years, with a median age of 37.0 years. The continuous cross-sectional area of the airway perpendicular to the centerline was obtained by Mimics software. The area was compared with the discontinuous cross-sectional areas reconstructed by conventional CT 3D reconstruction software advantage workstation, also the length of cervical trachea, the length of stenosis, and the minimum airway area were compared. Multi-factor linear stepwise regression method was used to analyze the factors influencing the measuring difference between the two methods. Three patients with laryngotracheal stenosis were selected, and the measured stenosis length was compared with the surgical specimens to evaluate the accuracy of the two methods. SPSS 26.0 software was used for statistical analysis. Results: In normal people, the areas of thyroid cartilage notch, glottis, inferio thyroid cartilage margin, inferio cricoid cartilage margin, and suprasternal notch planes measured by Mimics centerline method were smaller than those measured by conventional CT 3D reconstruction (t _{thyroid cartilage notch}=4.685, t_glottis=3.791, t_{lower thyroid cartilage margin}=5.621, t_{lower cricoid cartilage margin}=6.312, t_{suprasternal notch plane}=6.436, P<0.05). And the airway length measured by Mimics centerline method from the inferior thyroid cartilage to the superior sternal notch was longer (t=9.79, P<0.001). In laryngotracheal stenosis, in the non-tracheotomy group, the minimum airway area measured by Mimics centerline method was smaller and the stenosis length was longer than those measured by the conventional CT 3D reconstruction, and the difference was statistically significant (t_{minimum airway area}=2.562, t_{stenosis length}=5.240, P<0.05). In the tracheotomy group, the stenosis length measured by Mimics centerline method was longer than that measured by conventional CT 3D reconstruction, and the difference was statistically significant (t_{stenosis length}=2.854, P<0.05). Multi-factor linear regression analysis showed that different CT thickness had a statistically significant effect on the difference in the length of stenosis measured by the two methods (b=-5.370, t=-3.306, P=0.004), and different tracheal forward angle had a statistically significant effect on the difference in the minimum airway area measured by the two methods (b=-0.419, t=-2.208, P=0.04). The difference between the measured length of the Mimics centerline method and the intraoperative specimens was less than 0.5 mm. Conclusion: The centerline extracted based on CT 3D reconstruction can precisely reflect the laryngotracheal morphology and measure laryngotracheal stenosis more accurately.

Transoral microresection for treatment of vocal cord lesions involving the anterior commissure may result in anterior glottic webs. In this study, we retrospectively reviewed 54 patients who underwent microsurgery for bilateral lesions involving the anterior commissure and categorized them into two groups. The keel placement and control groups received endoscopic keel placement and mitomycin C, respectively. During the follow-up of at least 1 year, the laryngeal web formation rate significantly decreased in the keel placement group compared with that in the control group (18.6% versus 54.5%, P < 0.05). Furthermore, the voice handicap index-10 scores for patients without web formation decreased in both the keel placement and control groups (P < 0.0001 and P < 0.001, respectively). A pseudomembrane covering the vocal cords was detected in 16.3% (7 of 43) cases after keel removal. A total of 100% (7 of 7) of these cases and 2.8% (1 of 36) of the other cases formed laryngeal webs (P < 0.0001). Endoscopic keel placement could be an effective method for preventing anterior glottic webs after surgery for bilateral vocal cord diseases involving the anterior commissure. The pseudomembrane observed at the time of keel removal may imply a high risk of web formation.

Laryngeal stenosis is a partial or complete narrowing of the endolarynx and has many etiologies. Common causes of laryngeal stenosis are iatrogenic (prolonged intubation, laryngeal surgery), external neck trauma, congenital, burns, ingestions, infection, and inflammation (gastroesophageal reflux or Wegener’s). Laryngeal stenosis secondary to trauma usually affects the posterior endolaryngeal region in adults and the subglottic region in children.1 Patients with mild to moderate laryngeal stenosis are usually asymptomatic and if otherwise, majority of the presenting signs and symptoms are mainly related to the airway, feeding and voice resulting to marked respiratory distress, dysphagia/odynophagia and altered voice, respectively. We present a case of hypopharyngeal, supraglottic and subglottic stenosis occurring 1 week after intubation.

Laryngeal trauma is rare compared to other head and neck traumas, but it occurs, it can be life threatening. As for treatment, a laryngeal fracture that involves displacement of cartilage or extensive injury requires appropriate surgical treatments. For severe laryngeal fractures, conservative management is usually preferred with placing a stent to prevent laryngeal stenosis. But the downside of placing stents in the larynx includes the risk of granulation and infection. In this report, the authors describe a 35-year-old patient, who was diagnosed with blunt laryngeal trauma and treated by Horizontal partial laryngectomy. The patient's post-operative breathing and voice were fair, and airway stenosis did not occur afterwards.
