AbstractThe thyroid cartilage and thyroid gland forming a lump at the suprasternal notch is a surprising congenital anomaly which I believe has not been previously reported.A case with co-existent low hyoid bone, pharyngo-oesophageal junction and intrathoracic cricoid cartilage with no cervical trachea is presented. Its pathogenesis is suggested and its surgical importance is discussed.

Objective When performing lightwand intubation, an improper transmitted glow position before tube advancement can cause intubation failure or laryngeal injury. This study was performed to explore the transmitted glow point corresponding to a priori chosen depth for lightwand intubation. Methods Before lightwand intubation, we marked the transmitted glow point from a bronchoscope on the neck when it reached 1 cm below the vocal cords. Lightwand intubation was then performed using this marking point. The distances from the mark to the upper border of the thyroid cartilage, upper border of the cricoid cartilage, and suprasternal notch were measured. Results In total, 107 patients were enrolled. The success rate of lightwand intubation using the mark was 93.5% (95% confidence interval, 88.7%–99.2%) at the first attempt. The marking point was placed 12.0 mm (95% confidence interval, 10.6–13.4 mm) below the upper border of the cricoid cartilage. Conclusion Anaesthesiologists should be aware of the appropriate point of the transmitted glow on the patient’s neck when performing lightwand intubation. We suggest that this point is approximately 1 cm below the upper border of the cricoid cartilage. Trial registration: ClinicalTrials.gov NCT03480035

A case of leiomyosarcoma of the cervical trachea is described, detailing clinical presentation, pathologic diagnosis and surgical management. The rarity of this tumor in this location accounted for difficulties in clinical diagnosis and pathologic classification. Surgical treatment involved resection of two thirds of the circumference of the infracricoid trachea, with partial resection of the cricoid cartilage and thyroid gland. The defect was reconstructed using bilateral “butterfly” advancement flaps and a latissimus dorsi myocutaneous island flap. The technique and advantages of the latissimus dorsi flap are briefly described.

The thyroid is a vascular endocrine gland with two lateral lobes connected by a narrow, median isthmus. Although a wide range of congenital anomalies of the thyroid gland has been reported in the literature, agenesis of the thyroid isthmus is a very rare congenital anomaly. Thyroid isthmus agenesis does not manifest clinical symptoms, and it can be confused with other thyroid pathologies. We describe a patient with no isthmus of the thyroid, associated with Graves-Basedow disease. Thyroid isthmus agenesis should be kept in mind in order for surgical procedures involving thyroid pathologies to be carried out safely.

Background: The thyroid gland is essential for normal growth of the body. This study assessed relation of external branch of superior laryngeal nerve to the superior pole of the thyroid gland. Subjects and Methods: This study was conducted on 25 human cadavers having 50 superior thyroid poles of both genders. Cadavers were classified based on age groups, group I was those with age less than 39 years and group II cadavers were those with age more than 40 years of age. Various measurements were performed on cadavers. Results: 14 cadavers were I group I and 11 were in group II. The mean mass was 67.2 Kgs in group I and 59.5 Kgs in group II, time elapsed after death was 481.5 minutes in group I and 476.4 minutes in group II, mean height was 1.74 meters in group I and 1.69 meters in group II, mean BMI found to be 22.3 kg/m2in group I and 20.1 kg/m2in group II. Height found to be significant between both groups (P< 0.05). The mean distance from EBSLN to cranial point of the thyroid gland was 6.66 mm in group I and 8.96 mm in group II. The mean transverse distance from superior thyroid artery to EBSLN was 3.55 mm in group I and 5.12 mm side in group II. The mean distance of the crossing point between the most cranial point of the thyroid lobe was 6.40 mm in group I and 11.47 mm in group II. The mean distance from the EBSLN to the midline of the neck was 19.80 mm in group I and 18.58 mm in group II. The mean distance from the EBSLN to the midline of the neck on the most cranial point of the cricoid cartilage was 18.77 mm in group I and 17.80 mm in group II. Conclusion: Authors found variation in measurements in left and right side in both group I and group II.

Transoral videolaryngoscopic surgery (TOVS) for laryngopharyngeal cancer developed by Shiotani et al., uses the laparoscopic surgical system and distending laryngoscope. This method enables precise procedures and en bloc resection under a good view with videoendoscope in the structurally complex laryngopharynx. The major indications are Tis-2, and selected T3 lesions of hypopharyngeal, oropharyngeal, and supraglottic laryngeal cancer. TOVS is also considered for resectable rT1 and rT2 radiation failure cases and selected T3–4 advanced cases following neoadjuvant chemotherapy. Patients with resectable lymph node metastases are treated by neck dissection. Major contraindications are cricoarytenoid joint fixation, circumferential invasion of more than half, bilateral arytenoid invasion, and invasion to the thyroid cartilage, cricoid cartilage, hyoid bone, deep pharyngeal constrictor muscle. Oncological outcomes are good in long-term survival and larynx preservation rates with sparing radiation in half of the patients. However, advanced T stage and N3 cases showed a worse prognosis. Regarding functional outcome, swallowing function can maintain in most patients. Postoperative voice impairment can occur after wound healing. TOVS has some advantages particularly for hypopharyngeal cancer, in maneuver with smaller diameter instruments and tactile sense, and in less invasiveness without a tracheostomy, compared to other transoral surgeries.

Objectives - to present topographic and anatomic characteristics of the larynx relationship with neck organs and structures in the intermediate fetal period of human ontogenesis. Material and methods. The study included 85 organocomplexes of the fetuses neck of both sexes, from the 14th to the 27th week of development. The study material was divided into 2 age periods: the first group - fetuses aged 14-20 weeks; the second group - 21-27 weeks. The classical morphological techniques were used: (macromicroscopic preparation, modified method of saw cuts according to N.I. Pirogov, histotopographic method). Results. Larynx syntopy with thyroid gland, cervical esophagus, thymus, submandibular glands was described in detail. Larynx skeletotopy with incisurae jugularis sterni, cervical vertebrae, hyoid bone, mandible was described quantitatively. Conclusion. The data, obtained as a result of the study, supplement the data on the topographic anatomy of larynx and some neck organs and structures in the prenatal period of human ontogenesis. The revealed formation features of larynx and other neck organs and structures topography can be used in the study of intravital anatomy.

Common Location

Chondroma of the laryngeal cartilage is a rare, benign neoplasm which can manifest as a neck mass or, if situated within the airway, as slowly progressive obstruction, hoarseness or dyspnea. The most common location for chondroma is the posterior lamina of the cricoid cartilage; the next most common locations are the thyroid, arytenoid and epiglottic cartilages. Chondroma and low-grade chondrosarcoma are difficult to distinguish from one another histologically. Although chondrosarcoma reportedly recurs, local surgical excision without radical margins and with long-term clinical follow-up is recommended. We report one case of thyroid cartilage chondroma and include a review of radiologic studies and histopathologic analysis results. We also report a second case with severe airway obstruction caused by a large cricoid chondroma. A review of the English language biomedical literature on laryngeal chondroma is included.
