“…Facial reanimation was performed with a greater auricular or sural nerve interposition graft, a hypoglossal-facial nerve graft, or cross-facial nerve grafting. 4,5,[7][8][9][10][11][12] In 3 of these cases, postoperative facial nerve function recovered to a House-Brackmann grade III within 2 to 4 years. 2,5,7 Preoperative angiography and embolization is helpful in cases of glomus faciale, as it is with all glomus tumors.…”

Glomus Faciale Tumors: A Report of 3 Cases and Literature Review

et al. 2017

Our objectives in reporting this case series are to familiarize readers with the rare occurrence of paragangliomas originating along the facial nerve and to provide a literature review. We describe 3 such cases that occurred at our tertiary care academic medical center. Two women and 1 man presented with a tumor adjacent to the vertical segment of the facial nerve. The first patient, a 48-year-old woman, presented with what appeared to be a parotid tumor at the stylomastoid foramen; she underwent a parotidectomy, transmastoid facial nerve decompression, and a shave biopsy of the tumor. The second patient, a 66-year-old man, underwent surgery via a postauricular infratemporal fossa approach, and a complete tumor resection was achieved. The third patient, a 56-yearold woman, presented with a middle ear mass; she underwent complete tumor removal through a transmastoid transcanal approach. All 3 patients exhibited normal facial nerve function both before and after surgery. Paragangliomas of the facial nerve are extremely rare, and their signs and symptoms are unlike those of any other temporal bone glomus tumors. Management options include surgical resection, radiologic surveillance, and radiotherapy. The facial nerve can be spared in selected cases.

“…2,3 Paragangliomas originating in the facial nerve (glomus faciale) are extraordinarily rare, as only 12 such cases have been previously reported in the literature (table ). 2,[4][5][6][7][8][9][10][11][12] Given their rarity, the optimal management is unclear.…”

“…Histologic confirmation reveals cells arranged in the Zellballen pattern, which includes spindle-shaped or polygonal cells arranged in nests surrounded by sustentacular cells (immunostained by S-100) and separated by fibrovascular stroma. 16 Additional targeted immunohistochemical markers may include chromogranin and CD56. 13 Metastasis from primary epithelial neoplasms undergoing neuroendocrine differentiation may be excluded due to the lack of cytokeratin staining.…”

Objectives To perform an evidence-based review evaluating presenting symptoms, imaging, and management for primary paragangliomas of the facial canal (PPFCs). Data Sources PubMed/MEDLINE, Embase, Cochrane Library, and Web of Science. Review Methods Studies were assessed for quality of evidence and bias with the Cochrane bias tool, GRADE, and MINORS criteria. Demographic data, imaging modalities, management strategies, and status at last follow-up were obtained. Results Sixteen studies met inclusion criteria. In total, 21 patients with PPFCs were identified, 19 of which were histologically confirmed. Most common presenting symptoms included unilateral facial nerve dysfunction (n = 14, 73.7%) and pulsatile tinnitus (n = 8, 42.1%). Mean time from reported onset of facial dysfunction was 17.8 months. Computed tomography findings included an expanded descending facial nerve canal (n = 13, 76.5%). All cases with magnetic resonance imaging reported enhancement with contrast. Of the 18 patients who had surgery, 16 (88.9%) underwent full tumor resection while 1 (5.6%) had partial tumor debulking with adjuvant radiotherapy. Overall improvement in facial weakness was documented in 5 of 9 patients (55.6%) with initial facial nerve dysfunction and >6-month follow-up. No evidence of tumor recurrence was reported. Conclusions PPFCs are extraordinarily rare vascular neoplasms of the temporal bone. Early imaging with both computed tomography and magnetic resonance imaging is essential for narrowing the differential diagnosis, assessing the extent of tumor invasion, and accurate surgical planning. Surgical tumor resection with subsequent facial nerve reconstruction is recommended for patients with facial nerve dysfunction, while tumor biopsy or debulking may be indicated when normal facial movement in present.

“…Paragangliomas are exceedingly rare causes of facial palsy but should be included in the differential diagnosis. 3 The clinical course of temporal bone glomus tumours reflects their slow growth and paucity of symptoms. Often, a significant delay in diagnosis occurs, and tumours may be large when first identified.…”
