Abstract

Background: Primary squamous cell carcinoma (SCC) of the parotid gland is a rare, aggressive malignancy often requiring radical parotidectomy with facial nerve sacrifice, particularly in T4b stage disease. The utility of neoadjuvant chemotherapy (NACT) in downstaging these tumors to facilitate functional nerve preservation remains controversial and under-reported in the literature. Case presentation: A 58-year-old male presented with a fixed, rapidly enlarging left preauricular mass classified as cT4bN2M0 (Stage IVA). The tumor involved the sternocleidomastoid muscle and encased the external carotid artery. Following a multidisciplinary tumor board decision, the patient underwent an extended course of six cycles of Paclitaxel and Carboplatin. The tumor exhibited a partial clinical response and significant central necrosis on imaging. Subsequently, a total parotidectomy was performed. Despite intraoperative fragility and adherence to deep vascular structures, the main trunk and primary divisions of the facial nerve were anatomically and functionally preserved. Histopathology confirmed high-grade SCC with perineural invasion limited to the distal excised branches, achieving clear margins. The patient received 66 Gy of adjuvant radiotherapy. At the 18-month follow-up, the patient remains disease-free with House-Brackmann Grade I facial function. Conclusion: Long-term facial nerve preservation is feasible in selected cases of locally advanced parotid SCC using a multimodal approach. Extended NACT may induce tumor necrosis and facilitate dissection along the neuro-vascular interface, provided that perineural invasion does not involve the main nerve trunk.

Abstract

Mumps-associated Sudden Sensorineural Hearing Loss (SSNHL) is a rare but catastrophic complication of epidemic parotitis, historically estimated to occur in 1 per 20,000 cases. Despite global vaccination efforts, the re-emergence of mumps in adolescent populations due to waning immunity poses significant otologic risks. This report documents a case of unilateral, profound SSNHL in a vaccinated pediatric patient, highlighting the diagnostic challenges when auditory symptoms manifest after the resolution of systemic parotitis. An 11-year-old Balinese male presented with acute-onset tinnitus and hearing loss in the left ear, occurring one week after the clinical resolution of bilateral parotid swelling. The patient had a history of basic immunization. Audiometric evaluation revealed profound sensorineural hearing loss in the left ear with a Pure Tone Average of 110 dB, while the right ear remained normal. Serological analysis confirmed acute mumps infection with a highly positive IgM titer (Index 11.0). Hematological profiling demonstrated leukopenia with a neutrophil shift. Despite a prompt and aggressive multimodal treatment protocol including high-dose intravenous methylprednisolone, oxygen therapy, and neurotrophic support, follow-up audiometry at 14 days revealed no functional improvement (Pure Tone Average 91.25 dB). In conclusion, mumps-induced SSNHL is characterized by rapid, irreversible cochlear destruction that frequently exhibits resistance to corticosteroid therapy. The dissociation between the resolution of systemic parotitis and the onset of otologic sequelae requires high clinical vigilance. This case emphasizes the critical need for serological confirmation in pediatric SSNHL and underscores the poor prognosis associated with this specific viral etiology.
