Sinonasal Anatomy.

It is imperative for all imaging specialists to be familiar with detailed multiplanar computed tomography imaging anatomy of the paranasal sinuses and adjacent structures. This article reviews, in brief, the radiologically relevant embryology of the sinonasal region and discusses the imaging anatomy of the nasal cavity and paranasal sinuses. Radiologists should understand the importance and clinical implications of identifying the numerous anatomic variations encountered in this region and prepare a structured report that provides a surgical road map to the referring clinician.

Imaging spectrum of rhino-orbital-cerebral mucormycosis secondary to COVID-19 infection: a reporting checklist.

In recent times, India has been in the midst of a notifiable epidemic of mucormycosis (a rare angio-invasive fungal infection), within the ongoing global coronavirus disease 2019 (COVID-19) pandemic. Epidemiological studies have reported the estimated prevalence of mucormycosis to be around 70 times higher in India as compared to the global data, even in the pre-COVID era. However, in the last 3 months, our city witnessed an unprecedented surge in cases of post-COVID-19-associated rhino-orbital-cerebral (ROC) mucormycosis.

A Proposed Grading System and Experience of COVID-19 Associated Rhino Orbito Cerebral Mucormycosis from an Indian Tertiary Care Center.

Mucormycosis is an opportunistic fungal infection. India faced an unprecedented increase in patients with post coronavirus disease 2019 (COVID-19) associated rhino-orbito-cerebral mucormycosis (ROCM). This study proposes a grading system which correlates the extent of the disease with the management plan.

Deossification of the Otic Bone in High Pressure CSF Otorhinorrhea: A New Radiological Finding.

To highlight a new radiological feature in a patient with labyrinthine malformation presenting with bilateral spontaneous high pressure cerebrospinal fluid (CSF) otorhinorrhea. Study design-retrospective case review. Setting-academic, tertiary cochlear implant center.

Surgical complications and their management in cochlear implantees less than 5 years of age: The KEMH Pune experience.

Objective: To evaluate the incidence of surgical complications of cochlear implantation and their management at K.E.M.

Bilateral Non-Hodgkin's Lymphoma of the Temporal Bone: A Rare and Unusual Presentation.

Primary lymphoma of the temporal bone is an unusual finding in clinical practice and bilateral affection is even more rare. To the best of our knowledge, there are no reports of bilateral primary temporal bone lymphoma without middle ear involvement in the English medical literature so far. We report, for the first time, a case of primary lymphoma involving both temporal bones which presented with left-sided infranuclear facial palsy.

Bilateral cochlear implantation under local anaesthesia in a young adult - A case report.

Objective: Cochlear implantation is routinely performed under general anaesthesia in most centres in the world. There have been reports of this surgery being performed under local anaesthesia and sedation for unilateral cochlear implantation. Our case study reports the first bilateral cochlear implantation carried out under local anaesthesia with sedation.

Normal Anatomy and Anatomic Variants of the Paranasal Sinuses on Computed Tomography.

It is imperative for all imaging specialists to be familiar with detailed multiplanar CT anatomy of the paranasal sinuses and adjacent structures. This article reviews the radiologically relevant embryology of this complex region and discusses the region-specific CT anatomy of the paranasal sinuses and surrounding structures. Radiologists also need to know the clinical implications of identifying preoperatively the numerous anatomic variations encountered in this region and prepare a structured report according to the expectations of the referring clinician.

Role of HRCT and MRI of the Temporal Bone in Predicting and Grading the Degree of Difficulty of Cochlear Implant Surgery.

This study proposes a grading system based on a 10-point scoring chart of high resolution computed tomography (HRCT) and magnetic resonance imaging (MRI) imaging findings in patients being assessed preoperatively for cochlear implantation. This system helps in objectively assessing the degree of difficulty of the surgical procedure and alerts the surgeons to any potential intraoperative complications. This is a prospective study carried out at a tertiary referral center where 55 patients with bilateral profound sensorineural hearing loss were evaluated by HRCT and MRI and subsequently underwent cochlear implantation.

Pediatric synovial sarcoma in the retropharyngeal space: a rare and unusual presentation.

Synovial sarcomas in the head and neck are extremely rare tumors, especially in the pediatric population. 3-5% of synovial sarcomas occur in the head and neck region displaying varied imaging and histopathological features resulting in frequent misdiagnosis. These tumors have a poor prognosis; hence early diagnosis and accurate classification based on imaging, histopathology, and immunohistochemistry are critical for prompt treatment.

Role of magnetic resonance imaging in cholesteatoma: the Indian experience.

The objectives are to evaluate role of magnetic resonance imaging (MRI) in diagnosis of cholesteatoma and correlate imaging findings with intraoperative findings, and to emphasize of role of imaging in the follow-up of postoperative patients for differentiating residual/recurrent cholesteatoma from granulation/inflammatory tissue. In this prospective study, 31 patients were evaluated with a specific MRI protocol and high resolution computed tomography of the temporal bones. These included patients with a strong suspicion of having a cholesteatoma on clinical examination and postoperative cases on clinical follow up.

Infranuclear facial palsy: importance of imaging the geniculate fossa.

Objective: To highlight the importance of imaging the geniculate fossa in patients with solitary infranuclear facial palsy.

Study Design: Prospective.

Setting: Tertiary referral center.

Case report - biofilm infection of a cochlear implant.

One of the most dreaded complications after cochlear implantation is infection. These infections are a challenge due to lack of any data regarding optimal methods of investigation and management. More often than not, these patients have to undergo explantation and revision surgery.

Extracochlear electrode extrusion.

Extracochlear electrode extrusion is a potentially under-recognized complication of cochlear implantation. As the age of implantation becomes younger, electrode extrusion is of concern due to future skull growth. Extrusion of several electrodes may compromise performance and thus require surgical reinsertion of the electrodes.

Proboscis lateralis with ipsilateral sinonasal and olfactory pathway aplasia.

Proboscis lateralis is a rare craniofacial malformation characterized by absence of nasal cavity on one side with a trunk-like nasal appendage protruding from superomedial portion of the ipsilateral orbit. High-resolution computed tomography and magnetic resonance imaging are extremely useful in evaluating this congenital condition and the wide spectrum of associated anomalies occurring in the surrounding anatomical regions and brain. We present a case of proboscis lateralis in a 2-year-old girl with associated ipsilateral sinonasal aplasia, orbital cyst, absent olfactory bulb and olfactory tract.
