Use of a sternocleidomastoid muscle flap to protect the carotid artery during laryngectomy

Objectives This paper describes a simple method of securing tissue coverage of the great vessels at the initial surgery by rotating the divided sternal heads of the sternocleidomastoid muscle, a routine step during laryngectomy, and approximating them to the prevertebral fascia. The paper presents an illustrated case example where this technique in a salvage laryngectomy repair resulted in a protected vascular axis following a salivary leak. Results Since utilising this technique, there has been a marked reduction in the requirement of subsequent flap procedures to protect vessels, and no episodes of threatened or actual carotid blowout.

Cervical Cystic Hygroma in an Older Adult: A case study

Cystic hygromas are very uncommon malformations in adults. In most of the cases, they present as a painless, fluctuant swelling, usually located in the neck region. They tend to grow extensively if not removed. Cystic hygromas can range from 1 mm to several centimeters in size and are filled with clear- to straw-colored fluid. Surgical treatment remains the gold-standard treatment for these tumors. In some cases they can be misdiagnosed with branchial cysts, swollen lymph nodes or other pathologies. When this malformation is present in the prevertebral fascia its surgical treatment is challenging, and some Authors advise its conservative treatment, which is in a great risk of its reoccurence. Because of potential malignant transformation in some percentage of branchial cyst cases, a similar situation was suspected. The present report describes a case of cystic hygroma of the left side of the neck in a 92-year-old female adult and its clinical, radiologic and operative features.

Cervical erector spinae plane block: a cadaver study

BackgroundCervical erector spinae plane (ESP) block has been described to anesthetize the brachial plexus (BP), however, the mechanism of its clinical effect remains unknown. As the prevertebral fascia encloses the phrenic nerves, BP and erector spinae muscles to form a prevertebral compartment, a local anesthetic injected in the cervical ESP could potentially spread throughout the prevertebral compartment. This study utilizes cadaveric models to evaluate the spread of ESP injections at the C6 and C7 levels to determine whether the injection can reach the BP and its surrounding structures.MethodsFor each of the five cadavers, an ESP injection posterior to the transverse process of C6 was performed on one side, and an ESP injection posterior to the transverse process of C7 was performed on the contralateral side. Injections were performed under ultrasound guidance and consisted of a 20 mL mixture of 18 mL water and 2 mL India ink. After cadaver dissection, craniocaudal and medial-lateral extent of the dye spread in relation to musculoskeletal anatomy as well as direct staining relevant nerves was recorded. The degree of dye staining was categorized as “deep,” “faint,” or “no.”ResultsThe phrenic nerve was deeply stained in 1 injection and faintly stained in 2 injections. Caudally, variable staining of C8 (100%) and T1 (50%) roots were seen. Faintly staining at C4 root was only seen in one sample (10%). There was variable staining of the anterior scalene muscles (40%) anterior to the BP and the rhomboid intercostal plane caudally (30%).ConclusionsUltrasound-guided cervical (C6 and C7) ESP injections consistently stain the roots of the BP and dorsal rami. This study supports the notion that the cervical ESP block has the potential to provide analgesia for patients undergoing shoulder and cervical spine surgeries.

Substernocleidomastoid Muscle Neck Lipoma: An Isolated Case Report

Introduction. We report this large neck mass, located behind the sternocleidomastoid (SCM) within the posterior cervical space and anterior to the prevertebral fascia. The mass is displacing the carotid sheath and its neurovascular contents medially. It extends almost the whole length of the SCM muscle all the way down to the lung apex. Case Presentation. A 30-year-old female patient presented to our clinic with a left anterior neck mass for a few months with dysphagia. The lipoma was excised completely along with level II to IV lymphadenectomy. A very small volume chyle leak was noted intraoperatively. The drain was removed 2 weeks later only to recur in one month. A new drain was placed by interventional radiology, and the drainage resolved completely. Discussion. The patient with mild dysphagia had a lipoma large enough to push vital structures away from their normal anatomical position. Due to the difficult location and the size of the lipoma, a meticulous formal lateral neck dissection was required. A 3D imaging like CT or MRI would be helpful to preoperatively plan the dissection. Substernocleidomastoid neck lipoma in our case is a rare benign tumor that was challenging to excise.

Intraoperative rupture of tuberculous pseudoaneurysm associated with spinal tuberculosis: A case report and literature review

Introduction: The increase in the incidence of tuberculosis in developing countries has resulted in increased reporting on more related complications. We report the successful management of an intraoperative spontaneous rupture of a tuberculous pseudo aneurysm associated with spinal tuberculosis. Methodology: We report the case of a 66 years old woman diagnosed with spinal tuberculosis of the T3/T4 vertebrae. During an anterior approach surgical reconstruction for the degenerative vertebrae, massive hemorrhage was observed after the removal of a portion of the prevertebral fascia of the affected vertebrae. This led to the exploration of the hilar fascia for the possibility of hilar hemorrhage, and when no hemorrhage was observed, aneurysm rupture was suspected. A portion of the hilar fascia was then sutured to the prevertebral fascia and the hemorrhage was partially controlled. Results: On the 32nd month post-operative follow-up, the symptoms of chest and back pain had disappeared and the tuberculous lesion eradicated. Conclusion: Presently, there are few reports on the successful treatment of intraoperative spontaneous rupture of tuberculous pseudoaneurysms. We therefore report on the successful management of such a case.

What We Do

The Hynes pharyngoplasty is the second most often performed procedure for velopharyngeal insufficiency in the United Kingdom and Ireland. A crucial step of the procedure is reliable fixation of the flaps onto the posterior pharynx wall. We prefer to fix the flaps to the prevertebral fascia. By using a manually straightened needle and a skin hook, in our hands, placement of this stitch can be made easier and faster.

Long-Term Survival After Coverage With Prevertebral Fascia for Abdominal Aortic Stump Closure

Abdominal aortic graft-enteric fistula is an uncommon but grave complication. Acceptable early results of its management have been reported in recent years, but aortic stump disruption remains a dreaded problem in the remote period. This report describes a case of a 71-year-old male with graft-enteric fistula following after a distant abdominal aortic aneurysm repair. The patient underwent 1-stage operation with extra-anatomic bypass preceding the complete removal of the infected aortic graft and intestinal repair. For coverage of the aortic stump closure, the prevertebral fascia was harvested as a flap and was successfully used to buttress the closure. Additionally, omental wrap was secured around the stump and around the area after complete graft removal. Postoperative intravenous antibiotic with meropenem was administered for 8 weeks, followed by suppression with ongoing oral antibiotic with trimethoprim–sulfamethoxazole for 6 months. Although sigmoidectomy and the left ureteral reconstruction were required, the patient is doing well without recurrent infection and without stump disruption after 8 years of follow-up.

Cervical Sympathetic Block: Fluoroscopy

In those patients with significant sympathetically maintained pain, repeated blocks may provide a therapeutic value and help facilitate physical therapy and rehabilitation. Cervical sympathetic blocks have been traditionally performed by using surface landmarks, however imaging-guided blocks are strongly recommended to avoid potential serious complications. Most preganglionic sympathetic efferents innervating the head, neck, and upper extremity either pass through or synapse at the stellate ganglion. This provides an ideal target for blockade of sympathetic innervation to the head, neck, and upper limbs. The stellate ganglion block can be performed at the C6 and C7 transverse processes. Fluoroscopy is a reliable method for identifying bony surfaces, which facilitates identifying the C6 and C7 transverse processes; however, this is only a surrogate marker, because the location of the cervical sympathetic trunk is defined by the fascial plane of the prevertebral fascia, which cannot be visualized with fluoroscopy.

Persistent cough associated with osteophyte formation and vagus nerve impingement following cervical spinal surgery

Persistent cough due to irritation of the vagus nerve by osteophytes resulting from cervical spinal surgery is a very rare condition. The authors report the case of a 49-year-old woman who presented with a persistent cough subsequent to cervical spinal surgery. One year after the initial operation, the patient underwent surgery to free the larynx from the prevertebral fascia and cut the pharyngeal plexus, but her symptoms persisted. In order to control the cough, she used a soft cervical collar with padding inserted in the left side so that the larynx would be pushed to the right, a solution she discovered on her own. Without the collar, she coughed uncontrollably. A CT scan was performed and showed an osteophyte that had developed at the level of the prosthesis. Based on these findings, the authors hypothesized that the cough was caused by vagus nerve irritation due to the osteophyte. The osteophyte was resected and the vagus nerve was moved to a position anterior to the carotid artery and was isolated by means of an autogenous tensor fascia lata graft. The patient's symptom disappeared immediately after the surgery. At the most recent follow-up visit, 18 months after surgery, the patient was symptom free and was pursuing regular daily activities without using a cervical collar.

Does Increased Electrocautery during Adenoidectomy Lead to Neck Pain?

OBJECTIVES: The objective was to assess the impact of electrocautery on complications in adenoidectomy. We sought to quantify cautery-related temperature changes in prevertebral fascia that may occur during the procedure, retrospectively evaluate the incidence of cautery-related complications, and prospectively assess the role of cautery in postoperative neck pain. METHODS: Three consecutive related trials were performed. Initially, adenoidectomy was performed on 20 fresh cadavers, using a thermister to evaluate temperature changes in the prevertebral fascia after electrocautery (30 watts over a 30-second period). Next, retrospective analysis of adenoidectomy complications in 1206 children over a 5-year period was performed. Based on these findings, a prospective study of the incidence of neck pain following adenoidectomy was performed in a cohort of 276 children. Adenoidectomy technique, wattage, and duration of electro-cautery were recorded for each child. Children with significant neck pain were evaluated with MRI. RESULTS: Peak thermister readings averaged 74°C, for a mean change of 51.8°C. Complications observed in retrospective analysis included neck pain (3), Grisel's syndrome (1), prolonged velopharyngeal insufficiency (1), retropharyngeal edema (1), and severe nasopharyngeal stenosis (1). The incidence of neck pain in the prospective study was 12% (33 pts), and was independent of adenoidectomy technique, cautery wattage, or duration of cautery use. MRIs revealed edema without abscess. CONCLUSIONS: Cautery can result in substantial temperature changes in the surgical adenoid bed. Despite this, the incidence of complications, specifically neck pain, associated with adenoidectomy is low, although underreported. Complications appear to be independent of adenoidectomy technique and cautery use.
