Aspergillosis Causing Orbital Subperiosteal Abscess in an Immunocompetent Child: A Rare Presentation.

Orbital abscesses are primarily seen in children as complication of ethmoid bacterial sinusitis. We report a case of invasive aspergillosis causing orbital abscess in an immunocompetent child which resolved with surgery followed by antifungal therapy. This case highlights need for histopathological, and microbiological examination, including fungal culture in such cases.

A Comparative Study of Acute Invasive Fungal Sinusitis During the First and Second Waves of the COVID-19 Pandemic.

We aimed to compare the demography, clinical profile, histopathology, fungal culture, radiology, surgery performed, medical therapy and outcomes of patients with acute invasive fungal sinusitis seen during the first and second waves of the COVID-19 pandemic by retrospectively reviewing their case records. Of 238 patients, 43(18.1%) presented during the first wave and 195(81.9%) during the second wave. Patients seen during the first wave were older (p = 0.04) and more likely to have visual impairment (p = 0.004), frozen eye (p = 0.012), altered sensorium (p = 0.007) and stage 3 disease (p = 0.03). Those seen during the second wave were more often COVID-19 positive and had newly diagnosed diabetes mellitus (p = 0.04)and stage 1 disease (p = 0.03). Most patients had a positive culture for Rhizopus species during both waves. Histopathology showed broad aseptate hyphae in all patients but angioinvasion was seen more often during the first wave (p = 0.04). The majority of patients were treated with endoscopic+/- open debridement followed by intravenous amphotericin B and oral posaconazole. While the overall survival rate was similar (first wave 65.1%; second wave 79%; p = 0.106), mortality after discharge was greater during the first wave (11.6% vs 1.5%; p = 0.001). Mortality was higher in patients with stage 3 disease (p = 0.003). Significant differences in clinical presentation, histopathology, radiological stage of disease and post-discharge survival were noted between the two waves of the COVID-19 pandemic, the causes for which were multi-factorial.

Post-traumatic transocular retained foreign body in the infratemporal fossa: a near miss.

The infratemporal fossa is an uncommon site for lodgement of foreign bodies. Fast-moving projectiles and displaced teeth may get impacted and have been described in the literature. However, foreign body lodgement in the retromaxillary space after transorbital passage is rare. The trajectory of the foreign bodies in such cases is difficult to predict and may not be suspected in the absence of overt clinical features. The authors present a case of a wooden splinter lodged within the infratemporal fossa after the patient sustained a lid injury with an orbital floor fracture. Imaging was equivocal; hence, endoscopic surgical exploration was undertaken, revealing the foreign body. A high index of clinical suspicion and rapid intervention is needed since unsuspected foreign bodies may cause further visual, infective or neurovascular complications. Approaches should be tailored on a case-by-case basis.

Endoscope-Assisted Removal of Post-Traumatic Orbital Epidermoid Inclusion Cyst: A Useful Adjunct.

Orbital epidermoid cysts are uncommon lesions within the bony orbit with varied symptomatology related to both the eye and the sino-nasal system. They are often slow-growing cystic masses which may cause facial asymmetry and visual loss due to pressure symptoms. Cross-sectional imaging such as computed tomography and magnetic resonance imaging are contributory and useful for assessment of the size and actual extent and should be mandatory before planning any surgical intervention. Open approaches and needle aspiration have been traditionally described; however, the use of the rigid nasal endoscope in the intraorbital compartment is a useful adjunct for exploration of the extent of the lesion and for complete surgical clearance. In this report, a 69 years old female with an old post- traumatic orbital epidermoid cyst which was removed completely using an endoscope via transorbital route was presented with the review of literature.

Kaposiform Haemangioendothelioma of the Sublingual Gland in an Adult.

Kaposiform haemangioendotheliomas (KHE) are extremely rare, borderline malignant, locally aggressive vascular tumours. KHE is usually found in the retroperitoneum, over the extremities, the soft tissues of the trunk, mediastinum and the head and neck regions. We present a very rare case of KHE of the sublingual gland in an adult, which was not associated with Kasabach-Merritt phenomenon and was resected completely without any recurrence. To the best of our knowledge, this is the first reported case in the literature of a KHE arising from the salivary glands in an adult.

External Auditory Canal Cholesteatoma Involving the Vertical Segment of the Facial Nerve: A Rare Case Report.

External auditory canal cholesteatomas (EACC), are rare, more so when they affect the facial nerve in its vertical mastoid segment. EACC are known to possess bone eroding properties, causing a variety of complications, similar to the better-known attic cholesteatomas. We describe here the novel surgical management of a case of EACC, affecting only the vertical segment of the facial nerve, causing seventh nerve palsy at the time of presentation. A 46 year old male, complaining of right-sided otalgia and otorrhea, presented with grade IV facial palsy and associated mild conductive hearing loss. Clinical examination and radiological investigations suggested the diagnosis of an external auditory canal cholesteatoma. The patient underwent a trans-canal facial nerve decompression along with the cholesteatoma removal. Post-operatively, the patient showed marked clinical improvement with the facial palsy reverting to grade II. EACC involving only the vertical segment of the facial nerve can be approached via the trans-canal route, in contrast to the conventional postauricular approach, with a good clinical outcome. To the best of our knowledge, our case pertains to the only case of EACC with complications, managed by trans-canal facial nerve decompression.

Extratemporal intraparotid facial nerve schwannoma.

Schwannomas of the eighth nerve are common, usually found in syndromic association with neurofibromatosis-2. The occurrence of seventh nerve schwannoma, especially in its extratemporal course, is very rare. Here, we present a case report of an extratemporal facial nerve schwannoma diagnosed preoperatively with cytopathology and postoperative histopathologic confirmation. Histopathology provides the confirmatory diagnosis in such cases. An atypical diagnosis of neural schwannomas should be kept in mind when facial palsy is clinically encountered in the absence of any other aetiological factors.
