Submental intubation in complex maxillofacial trauma: Pilot balloon protection

AIMS

This study aims to describe our refined technique of submental intubation to avoid the recorded intraoperative complications related to tube passage and pilot balloon rupture.

CASE SERIES

This is a retrospective case series of 21 patients with complex maxillofacial trauma who underwent submental intubation from January 2019 to January 2023. All the patients underwent to the same procedure with a new technique of pilot balloon protection: the pilot balloon was not deflated because, once the connector was removed, only the tube was curved and passed through the incision extraorally while the cuff remained inflated. The wire of the pilot balloon was passed behind the last tooth so as not to interfere with the maxillary-mandibular fixation, remaining extraorally under the anesthetist's view.

DISCUSSION

Only 2 patients (9.5%) reported complications related to submental intubation: in particular a patient (4.8%) reported oral floor infection, and in another patient (4.8%) an unesthetic skin scar was observed. No patients reported intraoperative complications related to the procedure.

CONCLUSION

The technique of pilot balloon protection that we have proposed seems to be effective in reducing the intraoperative complications related to the passage of the pilot balloon, such as rupture, damage or early extubation.

Submental intubation versus tracheostomy in maxillofacial fractures

OBJECTIVE

To compare submental intubation with tracheostomy in patients with maxillofacial fractures who were operated under general anesthesia and nasotracheal intubation was contraindicated.

PATIENTS AND METHODS

This prospective comparative study was conducted on 32 patients undergoing maxillofacial operations. All patients had a panfacial trauma (including naso-ethmoid orbital fracture combined with mandibular fracture). Patients who had unstable cervical vertebra, laryngeal trauma, urgent tracheostomy, and patients with expected prolonged postoperative ventilation were excluded from the study. Patients were randomly assigned to elective tracheostomy and submental intubation groups. The patients were evaluated according to the time required to do elective tracheostomy or submental intubation, the operation comorbidity and complications, and the postoperative scar.

RESULTS

The average time required to do submental intubation was 8.35 min versus 30.75 min required to do elective tracheostomy with significant difference (p < 0.0001). No complication was reported with submental intubation while in elective tracheostomy group, surgical emphysema was registered in two patients. The submental scar was acceptable in all patients while the tracheostomy scar needs scar revision in four cases (p = 0.0325).

CONCLUSION

Submental endotracheal intubation appeared to be a simple, safe, and significantly faster reliable alternative to tracheostomy during surgical reconstruction of selected cases of maxillofacial fractures without indication for prolonged postoperative ventilation support with significantly lower morbidity.

Submental intubation: alternative short-term airway management in maxillofacial trauma

Objectives

To assess submental route intubation as an alternative technique to a tracheostomy in the management of the airway in cranio-maxillofacial trauma, along with an assessment of its morbidity and complications.

Materials and Methods

Submental intubation was performed in 17 patients who had maxillofacial panfacial trauma and management was done under general anesthesia during a period of one year from 2013 to 2014 at Departments of Oral and Maxillofacial Surgery and Dentistry, the Malankara Orthodox Syrian Church Medical College, Kochi, India.

Results

In all 17 cases, the technique of submental intubation was found to be simple and reliable. Hypertrophic scars were noted in three cases, orocutaneous fistula and mucocele in one case each. All these complications were managed comfortably without significant morbidity to the patient.

Conclusion

Submental intubation is a good technique that can be used regularly in the management of the airway in cranio-maxillofacial trauma, but with some manageable complications.

Minimally traumatic submental intubation: a novel dilational technique

PURPOSE

Submental intubation is widely accepted as a safe and effective alternative to nasal intubation or tracheostomy in head and neck surgery patients. Forceful or careless technique can cause significant bleeding and trauma to the soft tissues at this point, increasing the likelihood of troublesome sublingual haematoma.

METHODS

We describe the use of a percutaneous tracheostomy horn (Cook Medical Blue Rhino^®) to allow minimally traumatic submental intubation without the need for serial dilations. A patient with severe midfacial injuries requiring surgery was intubated via a standard oral technique. Following this, submental access was achieved using a novel dilational technique with a tracheostomy dilator. This resulted in a very secure and safe submental intubation and unrestricted access to the entire surgical field.

RESULTS

The single instrument, one-pass dilation technique to achieve submental intubation was found to be easy, quick, and avoided excessive trauma to the floor of mouth.

CONCLUSION

Patients will sometimes require a protected airway that allows surgeons unrestricted and simultaneous access to the dental occlusion, oral cavity, midface, and nose. In our case, this simple, easy, and quick adaptation of an established technique using a tracheostomy dilator is an excellent alternative to the traditional blunt dissection used to achieve submental intubation.

Assessment of the Efficacy of Submental Intubation in the Management of Midfacial and Panfacial Trauma Patients

INTRODUCTION

Securing an airway in maxillofacial injuries remains a challenge and is an important objective on the part of a maxillofacial surgeon to thoroughly understand its management.

PURPOSE

The aim of this study was to evaluate the efficacy and complications of submental intubation in the management of midfacial/panfacial trauma patients where oro-endotracheal or naso-endotracheal intubation is contraindicated and tracheostomy can be avoided.

PATIENTS AND METHODS

Twenty patients with maxillofacial injuries were selected for submental intubation who were admitted in Kamineni Hospital, Narketpally, Nalgonda during a 2 year period (2010-2012). The parameters used to assess the efficacy were; restoration of the occlusion, duration of the surgery, presence of scar, presence of infection, damage to vital structures or any post-operative salivary fistula.

RESULTS

Submental intubation allowed reduction and fixation of all fractures without the interference of the tube during surgical procedure in all of the patients. There were no intra-operative complications and none of the patients required post-operative ventilation. There were no significant post-operative complications. However, in one of the cases (case 4) infection of submental wound was seen and in another case (case 11) salivary fistula was formed. Both the cases were appropriately managed without any difficulty. The submental scar was well accepted by all the patients.

CONCLUSION

Submental intubation is a safe and extremely useful procedure in severe maxillofacial injuries. It presents a low incidence of operative and post operative complications. It allows both the surgeon and the anaesthetist to deliver a better quality of patient care.

[Patient treated with sub-mental intubation for maxillofacial trauma]

Maxillo-facial traumas are frequent and most often occur in young patients. Naso-tracheal or orotracheal intubation may be contraindicated in case of combined occlusal fracture and nasal or ethmoido-nasal fracture. This study was carried out a clinical case of a patient treated at the Lille University Hospital for a maxillofacial trauma associating fracture of nose and maxilla. The purpose was to assess the reliability of submental intubation as an alternative to tracheotomy. Submental intubation is a reliable single and safe technique allowing an one-stage surgical treatment in case of complex association of fractures without using tracheotomy. Its use should be implemented on a larger scale.

Current perspectives in intra operative airway management in maxillofacial trauma

OBJECTIVE

Maxillofacial trauma presents a complex problem due to the disruption of normal anatomy. In such cases, we anticipate a difficult oral intubation that may hinder intraoperative IMF. Nasal and skull base fractures do not advocate use of nasotracheal intubation. Hence, other anesthetic techniques should be considered in management of maxillofacial trauma patients with occlusal derangement and nasal deformity. This study evaluates the indications and outcomes of anesthetic management by retromolar, nasal, submental intubation and tracheostomy.

METHODOLOGY

Of the 49 maxillofacial trauma cases reviewed, that required intraoperative IMF, 32 underwent nasal intubation, 9 patients had tracheostomy, 5 patients utilized submental approach and 3 underwent retromolar intubation.

RESULTS

Among patients who underwent nasal intubation, eight cases needed fiberoptic assistance. In retromolar approach, though no complication was encountered, constant monitoring was mandatory to avoid risk of tube displacement. Consequently, submental intubation required a surgical procedure which could result in a cosmetically acceptable scar. Though invasive, tracheostomy has its benefits for long term ventilation.

CONCLUSION

Intubation of any form performed in a maxillofacial trauma patient is complex and requires both sound judgement and considerable experience.

Submental intubation: an alternative and cost-effective technique for complex maxillofacial surgeries

INTRODUCTION

Management of airway is a significant issue especially in cases of complex maxillofacial trauma like panfacial fractures or concomitant nasoethmoidal injuries, where the nasotracheal intubation is contraindicated or possess a significant problem. In these cases the only other alternative is tracheostomy. Submental intubation is an alternative to tracheostomy and it can be easily performed with little or lesser post-operative complications. This method involves lesser expenses as it does away with longer post-operative stay in the hospital as required by tracheostomy patients.

TECHNIQUE

The patient is orally intubated with a reinforced armoured tube with a detachable plastic gas connector. An incision is made in the submental area of the patient and a tunnel is prepared from this region to the floor of the mouth through which the proximal end of the tube is diverted. Thus the occlusion of the patient can be checked intraoperatively. After completion of the surgery the proximal end in reintroduced onto the oral cavity and the patient is extubated orally.

DISCUSSION

Originally proposed by Altemir in 1986, this method cannot be used in all cases as it is not without limitations. In spite of these, submental intubation can be a useful alternative to tracheostomy, especially in regions where cost cutting is a major factor in health infrastructure.

CONCLUSION

Maxillofacial surgeons addressing major facial trauma surgery may have this procedure in mind before opting for tracheostomy. It avoids a lot of complications associated with tracheostomy.

Submental intubation: our experience

INTRODUCTION

Airway management for patients who suffered midfacial fractures is complicated. In maxillofacial injuries, a choice has often to be made between different ways of intubation when surgical access to both the nasal and oral cavities is necessary. Submental intubation technique is an alternative to nasoendotracheal intubation and tracheostomy in the management of patients with severe midfacial fractures. This procedure is simple to do and has a low morbidity.

MATERIAL

Submental intubation-paramedian technique has been used in 15 cases from May 2005-April 2007 in Hosmat Hospital, Bangalore. All patients had fractures disturbing the dental occlusion plus either an associated fracture of the skull base or a displaced nasal fracture.

RESULTS

Average duration of procedure was 7 minutes. Average duration of tube in vitro after surgery was 20 hours. There were 2 postoperative complications of tube obstruction which were successfully managed.

CONCLUSION

Submental intubation demands certain technical skills but it is simple, rapid and may avoid tracheostomy in selected patients.

Submental intubation: An alternative to tracheostomy when nasoendotracheal intubation is unsuccessful - A case report

Submental intubation (SI) has been proposed as an alternative to nasoendotracheal intubation when oral endotracheal intubation is contraindicated. In patients who require intubation for maxillofacial reconstruction, this is an alternative to a traditional tracheostomy. The present case report presents an 18-year-old woman who suffered a comminuted mandibular fracture. Two days after her accident, she was taken to the operating room for open reduction with internal fixation of her mandible; however, the anesthesia staff was unable to nasally intubate the patient. A SI was performed. The procedure was completed without complications and the surgery accomplished with the SI. The patient was able to avoid a tracheostomy for an isolated operation. SI avoids the dangers of nasoendotracheal intubation in patients with midfacial fractures and avoids complications related to tracheostomy. Thus, SI may serve as an alternative to tracheostomy in patients without other medical conditions and indications for long-term intubation.
