Objective: The objective of this study was to discuss the characteristics of intracranial extension in patients with juvenile nasopharyngeal angiofibroma (JNA) and propose and an algorithm for its management.

Methods: A retrospective chart review of all patients with JNA who underwent operations between January 2013 and January 2023 was done, and those cases with intracranial extension categorized as stage IIIb, IVa, and IVb according to the Andrews modification of the Fisch staging classification were included in the study. Data were collected about age at presentation, symptoms, radiological findings, routes of intracranial extension, therapeutic management, and follow-up.

Article Synopsis
  • Thoracic tracheal tumors are uncommon and can present challenges for surgery and anesthesia, making their management complex.
  • This study focuses on the percutaneous trans-tracheal endoscopic approach (PTTEA) as a minimally invasive alternative for patients with tracheal tumors when traditional methods fail.
  • Out of 16 patients treated from 2015 to 2022, most had successful outcomes with benign tumors, while malignant tumors required further treatment after initial procedures; PTTEA proved to offer advantages like better access and fewer complications.

This study describes the clinical profile, operative findings, surgical technique, type of implant and complications encountered in implantation of abnormal cochlea by the transcanal (veria) technique in a tertiary care centre. This is a retrospective study done amongst 337 patients who underwent cochlear implantation by veria technique between January 2013 to August 2023. Based on pre-operative imaging with high-resolution computed tomography and magnetic resonance imaging the cochleovestibular malformations in this study were classified according to Sennaroglu classification and the cochlear ossification was graded from I to IV.

Pulsatile tinnitus (PT) is the perception of an auditory sensation without an external source and in synchrony with the heartbeat. One of the most common cases of PT is bony anomalies of the sigmoid sinus, including dehiscence or diverticula. This case report describes a 26-year-old female patient who presented with pulsatile tinnitus caused by sigmoid sinus diverticula and dehiscence, which was successfully treated with cortical mastoidectomy with diverticula closure using pedicled temporalis fascia and resurfacing of the dehiscence with autogenous bone pate along with bone cement.

Benign parotid tumors follow an indolent course and present as slow-growing painless swelling in the pre-and-infra-auricular areas. The treatment of choice is surgery. Though the gold standard technique is Superficial Parotidectomy, Extracapsular Dissection (ECD) is an alternative option with the same outcome and decreased complications.

Purpose: While extensive research with accurate classification has been done in mycoses of the paranasal sinuses and anterior skull base, a similar understanding of lateral skull base fungal pathologies is lacking due to relative rarity and diagnostic difficulties. We introduce a series of eleven cases and two different invasive entities of Aspergillus temporal bone diseases-fungal skull base osteomyelitis (SBO)/malignant otitis externa (MOE) and chronic invasive granulomatous fungal disease (CIGFD).

Methodology: A retrospective observational study was conducted at the neuro-otology unit of a tertiary care referral center between July 2017 and November 2022.
