Preserving the thyroidal isthmus during low tracheostomy with creation of a Björk flap

Safety and efficacy of high tracheostomy with inferior retraction of the thyroid isthmus

OBJECTIVE

In typical surgical tracheostomy, the thyroid isthmus is divided or retracted superiorly and preserved. However, at our institution, the thyroid isthmus is retracted inferiorly and preserved. Thereafter, a tracheal incision is made above the thyroid isthmus. This method, hereinafter defined as high tracheostomy, has the advantage of facilitating immediate access to the trachea in a superficial position; moreover, it can be quickly replaced with cricothyrotomy in emergency situations. However, tracheotomies placed too high can potentially damage the cricoid cartilage, thereby causing subglottic granulation and tracheal stenosis. We aimed to validate the safety and efficacy of high tracheostomy with inferior retraction of the thyroid isthmus.

METHODS

This was a retrospective cohort analysis. We analyzed the operative method and other relevant characteristics of 90 patients who underwent surgical tracheostomy between April 2016 and June 2022. For those who underwent high tracheostomies, we analyzed the duration of surgery, amount of intraoperative bleeding, occurrence of complications, problems with stoma closure, and perioperative mortality.

RESULTS

High tracheostomy was performed in 73 patients. Subglottic granulation occurred in one patient, and the granulation tissue spontaneously shrank. Subcutaneous emphysema occurred in two patients. No patient developed wound infection or tracheoinnominate artery fistula. Moreover, no patient experienced false route tracheotomy tube insertion because the thyroid glands were located under the stoma.

CONCLUSION

The frequency of complications was comparable to that reported in other studies on tracheostomy. Additionally, no patient developed tracheal stenosis secondary to tracheostomy above the thyroid isthmus. Therefore, high tracheostomy with inferior retraction and preservation of the thyroid isthmus is safe and advantageous.

The Impact of the COVID-19 Pandemic on Urgent Awake Tracheotomies in Adults

Objective This study aims to investigate the impact of the COVID-19 pandemic on urgent awake tracheotomies (UATs) in adults in a reference center. Methodology During the pandemic (between March 2020 and May 2022) and before the pandemic (between January 2018 and March 2020), medical charts of patients who underwent UATs were reviewed. The analysis focused on demographic characteristics, indications, COVID-19 positivity status, surgical procedures, and complications. Results During the pandemic, 67 UATs (age 62.04 ± 11.9 years) were performed. Of the indications, 56 (83.5%) were malignancy. Before the pandemic, 22 UATs (age 63.86 ± 15.1 years) were performed, of which 14 UATs (63.6%) were due to malignancy. There was a significant increase in UATs and their indications in patients with head and neck malignancies (P < 0.05). Stay suture (65, 97%) and suture ligation of the thyroidal isthmus (61, 91%) were significantly performed during the pandemic (P < 0.05). Conclusions A significant increase in UAT was detected, especially in patients with advanced head and neck cancer. Pandemic conditions and the risk of viral transmission have led to more conservative UAT techniques.

A new nomogram to predict the need for tracheostomy in burned patients

Purpose

To evaluate the impact of tracheostomy on complications, dysphagia and outcome in second and third degree burned patients.

Methods

Inpatient mortality, dysphagia, severity of burn injury (ABSI, TBSA) and complications in tracheotomized burn patients were compared to (I) non-tracheotomized burn patients and (II) matched tracheotomized non-burn patients.

Results

134 (30.9%) out of 433 patients who underwent tracheostomy, had a significantly higher percentage of inhalation injury (26.1% vs. 7.0%; p < 0.001), higher ABSI (8.9 ± 2.1 vs. 6.0 ± 2.7; p < 0.001) and TBSA score (41.4 ± 19.7% vs. 18.6 ± 18.8%; p < 0.001) compared to 299 non-tracheotomized burn patients. However, complications occurred equally in tracheotomized burn patients and matched controls and tracheostomy was neither linked to dysphagia nor to inpatient mortality at multivariate analysis. In particular, dysphagia occurred in 6.2% of cases and was significantly linked to length of ICU stay (OR 6.2; p = 0.021), preexisting neurocognitive impairments (OR 5.2; p = 0.001) and patients’ age (OR 3.4; p = 0.046). A nomogram was calculated based on age, TBSA and inhalation injury predicting the need for a tracheostomy in severely burned patients.

Conclusion

Using the new nomogram we were able to predict with significantly higher accuracy the need for tracheostomy in severely burned patients. Moreover, tracheostomy is safe and is not associated with higher incidenc of complications, dysphagia or worse outcome.

National questionnaire on skills and techniques in pediatric tracheotomy surgery in Turkey

OBJECTIVE

The aim of the study was to determine the differences in surgical preferences of ENT Surgeons in Turkey with regard to pediatric tracheotomy.

DESIGN

Questionnaire study.

PARTICIPANTS

ENT Surgeons.

MATERIALS AND METHODS

The national multiple-choice questionnaire study included a total of 16 questions about physicians technical preferences, different methods and complications in pediatric tracheotomy surgery. It was planned and implemented with the support of a professional survey company (www.surveymonkey.com).

RESULTS

The questionnaire was answered by 591 ENT Surgeons; the percentage of the physicians performing pediatric tracheotomies in the previous year was 59.6%. Forty point four percent (40.4%) of the physicians had not performed tracheotomies in the pediatric age group and 57.9% had not performed tracheotomies in patients under one year old. Seventy point six percent (70.6%) of the physicians who had performed tracheotomies had made vertical skin incisions, 69.5% of them had removed subcutaneous adipose tissue, 81.4% of them had retraction the thyroid isthmus area from their field of view; 83.9% of them had made a vertical incision to the trachea, 82.5% of them had applied a stay suture to the trachea and 4.7% of them had used additional techniques for stoma maturation. The intraoperative mortality, early complication, late complication, and total complication rates were 3.9%, 32.7%, 21.2% and 53.9 respectively.

CONCLUSIONS

This is the first large-scale questionnaire study with data on pediatric tracheotomy techniques and the practices of ENT Surgeons at a national level. Common approaches were observed among the.

Tracheostomy in bilateral neck dissection: Comparison of three tracheostomy scoring systems

OBJECTIVES

To evaluate whether elective tracheostomy is justified after tumor resection and bilateral neck dissection (ND) and whether application of tracheostomy scoring systems is reliable for planning of postoperative airway management.

STUDY DESIGN

Retrospective cohort study.

METHODS

We retrospectively assessed airway management in 160 patients with head and neck squamous cell carcinomas. Additionally, we applied and analyzed the 1) Cameron, 2) TRACHY, and 3) CASST tracheostomy scoring systems on the tracheostomy recommendations.

RESULTS

Elective tracheostomies were performed in 51.3% of our patients, particularly in T3 to T4 tumors, cases with free flap reconstruction, and concurrent procedures. Among patients undergoing concurrent procedures, those who received tracheostomy showed significantly longer inpatient stays (27.8 ± 30.0 days vs. 13.3 ± 6.6 days; P < 0.001). Tracheostomy recommendation coincides with the performance of bilateral ND in 28.6% (CASST), 60.0% (Cameron), and 75.0% (TRACHY) of the cases, respectively. By applying corresponding criteria, tracheostomy would be recommended in 2.5% (CASST), 76.9% (Cameron), and 84.4% (TRACHY) of our cases. Bleeding episodes were the most common complication occurring in 10 patients (6.3%), but tracheostomy scores did not significantly differ between bleeders and nonbleeders.

CONCLUSION

Bilateral ND on its own is not a reliable predictor for elective tracheostomy. Furthermore, given the significant heterogeneity of currently available scoring systems, they prove inadequate for decision making and predictive modeling of tracheostomy placement.
