“…Postoperative results vary in a review of the literature and ranged from complete recovery with normal function, to a variety of deficits that included hoarseness, dysphagia, vocal cord palsy, and vocal cord paralysis. In the cases of vocal cord paralysis, some patients experienced improved symptoms or even complete recovery over time . As expected, subtotal resections achieved a higher rate of gross nerve preservation than did gross total resections (97% vs 29%).…”

Vagal schwannomas of the head and neck: A comprehensive review and a novel approach to preserving vocal cord innervation and function

et al. 2019

Background: Schwannomas, benign tumors arising from neurolemmocytes, are the most common type of peripheral nerve tumors. Extracranial schwannomas are most often found in the parapharyngeal space, commonly involving the vagus nerve to cervical sympathetic trunk. Vagal schwannomas present several unique clinical and therapeutic challenges. Methods: A comprehensive literature review was conducted on 197 articles reporting 235 cases of cervical vagal schwannomas. Presenting symptoms, treatment approach, and postoperative outcomes were recorded and analyzed. Results: Vagal schwannomas commonly present as asymptomatic neck masses. When they become symptomatic, surgical resection is the standard of care. Gross total resection is associated with higher postoperative morbidity compared to subtotal resection. Initial reports using intraoperative nerve monitoring have shown improved nerve preservation. Recurrence rates are low. Conclusion: The combination of intermittent nerve mapping with novel continuous vagal nerve monitoring techniques may reduce postoperative morbidity and could represent the future standard of care for vagal schwannoma treatment.

“…The term ‘schwannoma’, first introduced in 1935 by Stout, identifies a benign tumour with sporadic malignant degeneration arising from cranial, peripheral and autonomic nerve sheath cells [ 1 ]. It represents 5% of all benign soft tissue tumours [ 1 ], equally affects both genders and typically shows higher incidence between the third and fifth decade [ 2 , 3 ]. Head and neck localization is infrequent, and vagal origin in that region is unusual [ 1 , 3 , 4 ].…”

A literature review on surgery for cervical vagal schwannomas

et al. 2015

Cervical vagal schwannoma is a benign, slow-growing mass, often asymptomatic, with a very low lifetime risk of malignant transformation in general population, but diagnosis is still a challenge. Surgical resection is the treatment of choice even if its close relationship with nerve fibres, from which it arises, threats vagal nerve preservation. We present a case report and a systematic review of literature. All studies on surgical resection of cervical vagal schwannoma have been reviewed. Papers matching the inclusion criteria (topic on surgical removal of cervical vagal schwannoma, English language, full text available) were selected. Fifty-three patients with vagal neck schwannoma submitted to surgery were identified among 22 studies selected. Female/male ratio was 1.5 and median age 44 years. Median diameter was 5 cm (range 2 to 10). Most schwannoma were asymptomatic (68.2%) and received an intracapsular excision (64.9%). Postoperative symptoms were reported in 22.6% of patients. Cervical vagal schwannoma is a benign pathology requiring surgical excision, but frequently postoperative complications can affect patients lifelong, so, surgical indications should be based carefully on the balance between risks and benefits.

A Case of Cystic Schwannoma in the Neck Masquerading as Branchial Cleft Cyst

et al. 2014

One-third of schwannomas occur in head and neck region, mostly in the parapharyngeal region. Cystic change is seen in only 4% of schwannomas. The diagnosis of such tumors remains a challenge due to the rarity of these lesions and limited utility of fine needle aspiration cytology. When cystic, branchial cleft cyst is an important differential diagnosis more so due to radiological resemblance. We present a case of 42-year-old male with left sided neck mass masquerading as branchial cleft cyst clinically and radiologically. Multiple sections examined from the cystic areas of the mass revealed lymphoid aggregates beneath the cyst wall in addition to the schwannomatous areas.
