Background: Upper cervical spinal ependymomas (uCSE) is routinely identified as intramedullary ependymomas located from the oblongata medulla to C4 level. Our study aimed to report the outcomes and treatment profiles of uCSE from our cohort of uCSE patients.

Methods: This retrospective observational study included 108 patients with upper cervical spinal ependymomas (uCSE) who underwent surgery at Huashan Hospital from 2008 to 2022. Demographic and clinical data were collected to identify risk factors may associated with post-operative spinal cord function, quality of life and respiratory function.

Results: The mean age of included patients was 44.30 ± 12.71 years old. The most common uCSE was ependymoma (103 of 108, 95.37 %), followed by subependymoma (3 of 108, 2.78 %) and anaplastic Ependymoma (2 of 108, 1.85 %). Age (P = 0.003), sex (P = 0.004), duration of symptoms (P = 0.010), pre-operative bladder functions (P = 0.012), post-operative pneumonia (P = 0.013) and Carbon Dioxide Retention (CDR) (P = 0.004) could independently correlate with Iiving quality of uCSE patients. Post-operative spinal cord function was associated with pneumonia immediately after operation (P = 0.017). In addition, post-operative pneumonia correlated with tumor location (P = 0.048), pre-operative McCormick scores (P = 0.008)/ motor functions (P = 0.022)/ NRS scores (P = 0.020), and tracheotomy immediately after operation (P < 0.001). Tracheotomy immediately after operation was associated with tumor location (P = 0.023), unsteady walking (P = 0.033), pre-operative NRS scores (P = 0.029), post-operative pneumonia (P < 0.001) and CDR (P < 0.001).

Conclusion: Within uCSE patients, post-operative quality of life is associated with pre-operative spinal cord function and symptom duration, which emphasizing the importance of early intervention. Their post-operative respiratory dysfunctions also correlated with post-operative spinal cord function and quality of life.

Respiratory Distress Arising from a Peripheral Osteoma: A Rare Case Report.

Indian J Otolaryngol Head Neck Surg

January 2025

Department of Oral Medicine and Radiology, JSS Dental College and Hospital, JSS Academy of Higher Education and Research Mysuru, Karnataka, 570015 India.

This case report highlights a rare occurrence of respiratory distress caused by a peripheral osteoma on the lingual mandibular surface. It underscores the importance for otolaryngologists to consider atypical bone growths in differential diagnoses of dyspnea. The case emphasises the value of CBCT in detecting and managing such uncommon maxillofacial pathologies affecting the upper airway.

Unlabelled: Nasal polyp (NP) is a pathological benign mass that affects the nasal cavity and paranasal sinuses. This lesion is occasionally associated with chronic rhinosinusitis (CRS), which is named chronic rhinosinusitis with nasal polyps (CRSwNP). Proliferating cell nuclear antigen (PCNA) indicates abnormal cell proliferation which may help assess the nasopharyngeal lesions and upper airway cancers.

Unlabelled: The retropharyngeal space is a distinct space along the midline that extends from the skull base to the upper mediastinum. Retropharyngeal space lesions can produce significant morbidity, given their proximity to the aero-digestive tract, skull base and its ability to extend into upper mediastinum. Difficulty in assessing the retropharyngeal space by direct inspection or physical examination may cause delay in diagnosis and early intervention thus knowledge about these lesions and their effective management is essential.

Peripheral Odontogenic Myxoma in Anterior Maxilla: A Case Report.

Indian J Otolaryngol Head Neck Surg

February 2025

Department of Oral Pathology and Microbiology, King George's Medical University, Lucknow, 226003 India.

Peripheral odontogenic myxoma (POM), a rare and extra-osseous variant of odontogenic myxoma (OM), is classified as a relatively rare benign odontogenic tumour, yet presenting with locally aggressive behaviour and a wide range of variable clinical presentations. The objective of this case report is to present a patient who reported with the complaint of pus discharge in upper front region of the jaw, in the past one month. No associated history of tooth loss, impacted teeth or intracanal infection was noted clinically as well as radiographically.

Acute sinusitis is a relatively common condition in pediatric patients. In most cases, it resolves completely with prompt medical management, but its rapid progression to severe orbital complications leading to restriction of extra-ocular movements and negative perception of light in the affected eye is rare and pose diagnostic and management challenges. The aggressive nature of acute rhinosinusitis requires urgent surgical intervention coupled with prompt medical management to prevent life threatening complications and outcomes.
