The cricoid cartilage has been regarded as an extremely important organ because it plays important role in both of phonation and breathing. We herein report on two different types of surgical procedure for laryngotracheal diseases with aggressive resection of the cricoid cartilage. The first procedure is a tracheostomaplasty by partial resection of the cricoid cartilage. A tracheostoma is made by resection of the cricoid cartilage in the range of approximately a one-third front. This method is effective for such cases having difficulty in tracheostomy owing their backgrounds with such condition as neck stiffness, obesity, higher displacement of the brachiocephalic artery, short neck, thyroid disease and so on. We applied this procedure for eight cases with such difficult backgrounds. In all cases, we were able to make a good tracheostoma and the postoperative courses were uneventful. The second procedure is a glottic closure with resection of the cricoid cartilage and thyroid cartilage. We applied this procedure for six cases with intractable dysphagia. One case had a postoperative bleeding. We were able to make good conditions in all cases with a large tracheostoma and no pharyngeal-tracheal leakage. In conclusion, the surgical procedure involving resection of the cricoid cartilage can be applied to some laryngotracheal diseases.

Laryngeal chondroma is a very rare laryngeal tumor that commonly presents as dysphonia and dyspnea. A combination of clinical, histological, and radiological data has paramount importance for accurate diagnosis of this rare disease. It is difficult to differentiate laryngeal chondroma from chondrosarcoma solely based on radiological imaging; therefore, radiologists need to specify the origin of the tumor and the level of extension.

Introduction: Laryngeal chondrosarcoma (CS) is a rare indolent malignant tumor. High-grade (G3), dedifferentiated (DD), and myxoid (MY) CSs are considered more aggressive subtypes due to their metastatic potential and relatively poor outcomes. The aim of this systematic review is to evaluate treatment modalities and survival outcomes in patients affected by these rarer CS subtypes.

The laryngeal mound (LM) formed the caudal part of the pharyngeal floor, which varied in position, shape, and length at different ages. This work aimed to study the morphogenesis of the LM in the embryonic and post hatching periods grossly, histologically, and by scanning electron microscopy using forty-eight Japanese quails. The LM primordia appeared on the 8th day of incubation as a raised elevation carried on a deep median symmetrical sulcus (glottis primordium).

To explore the application of spiral tracheoplasty in the repair of large tracheal defects after the resection of trachea invaded by thyroid cancer. A retrospective analysis was performed on the clinical data of 11 patients, including 4 males and 7 females, aged from 36 to 67 years old, with large tracheal defects after tracheal resection due to thyroid papillary carcinoma invading the trachea in the Department of Otorhinolaryngology Head and Neck Surgery, Second Xiangya Hospital, Central South University from January 2019 to January 2022. The range of tracheal defects, time of tracheal reconstruction, postoperative complications and airway were recorded, and the patients were followed up for more than 24 months.

Subglottic and posterior glottic stenosis (PGS) narrows distinct areas of the larynx, while bilateral vocal fold immobility (BVFI) is characterized by static cords. Treatments include open surgeries and newer endoscopic methods, offering comparable safety, quicker recovery, and fewer complications. This study assesses the decannulation rate of endoscopic posterior cricoid split with posterior cartilage grafting (EPCCG) in pediatric patients with posterior glottic stenosis, subglottic stenosis (SGS), and BVFI.
