Point-of-Care Ultrasound
Published in Kajal Jain, Nidhi Bhatia, Acute Trauma Care in Developing Countries, 2023
Approach:The objective emergency is to identify the cricothyroid membrane.Position of the transducer: Longitudinal with pointer towards the head slightly lateral to the midline of the trachea. The probe should be held with the non-dominant hand to identify airway structures (thyroid, cricoid and tracheal cartilages). In between the thyroid and cricoid cartilages, identify the cricothyroid membrane.Once the cricothyroid membrane is identified, a single horizontal incision is made medial to the probe with the scalpel through the membrane and surgical front of neck access is achieved.

Also called front of neck access, the surgical establishment of an airway through the cricothyroid membrane is now commonly taught as an airway rescue manoeuvre. It differs from a surgical tracheostomy in that it uses the superficial and accessible cricothyroid membrane as the point of access to the airway and has relatively few adjacent structures that can be damaged. Surgical cricothyroidotomy should be avoided in infants and young children (under 12) as it may cause upper airway collapse.

The vocal cords are formed by the thickening of the upper edge of cricothyroid membrane connecting to the arytenoid cartilage posteriorly. The white colour of the cords is because of the absence of the submucosal covering.

Postoperatively, he was transferred to the SICU for airway monitoring. On postoperative day 2, a modified barium swallow study obtained as part of a standard posttracheotomy evaluation revealed a soft tissue prominence between the trachea and cervical esophagus with associated mass effect. Computed tomography (CT) of the neck revealed glottic narrowing and a 2.7 × 1.0 × 2.2 cm posterior laryngeal fluid collection at the level of the true vocal folds with possible fragmentation of the cricoid cartilage (Figure 1). The patient was taken back to the operating room for repeat direct laryngoscopy. An area of posterior cricoid/glottic fullness was identified and aspirated using an 18-gauge needle via the cricothyroid membrane under direct visualization from above (Figure 2a). The abscess cavity was then incised using a CO2 laser (4 W, line pattern generator) fixed to a micromanipulator, followed by blunt/sharp dissection yielding additional purulence (Figure 2b). Cricoarytenoid joints were injected with 0.5 mL of triamcinolone 40 mg/mL.
The prognostic value of thyroid gland invasion in locally advanced laryngeal cancers

Cricothyroid membrane (conus elasticus) is one of the common route of extralaryngeal spread of larynx cancer. This is categorized and well reported as the inferior route of extralaryngeal spread by Chen et al. [3]. The tumor that exceeds the cricothyroid membrane, cricoid cartilage, and cricotracheal membrane with inferior extralaryngeal spread would invade thyroid gland due to close proximity anatomically. Considering that the most common form of TGI is direct invasion, the subglottic extension and cricoid cartilage invasion are the main risk factors for TGI due to the characteristics of inferior route. In fact, the results of the current studies mentioned above are demonstrated this situation [1–3,14–16]. In our study, the presence of inferior extralaryngeal spread was confirmed in all the patients with TGI. In addition, we found the prevalence of TGI as 52% (13/25) in patients with inferior extralaryngeal spread.

Misidentification of the external cricoid landmarks is a common pitfall that can result in tube misplacement; therefore, making an initial vertical incision is recommended by most experts (56–58). Many authors recommend placing a hook into the incision after incising the cricothyroid membrane to ensure identification and anchoring of the tract, and this is especially helpful in obese patients (54, 55, 59). When using an endotracheal tube rather than a tracheostomy tube, care should be taken not to advance it too deeply, causing a mainstem intubation.
