Use of cribriform amplatzer septal occluder in the pediatric population: Feasibility, safety, and technical considerations.

Ann Pediatr Cardiol 2021 Apr-Jun;14(2):159-164. Epub 2021 Apr 10.

Department of Pediatric Cardiology, NHSRCC Hospital, Mumbai, Maharashtra, India.

Purpose: Fenestrated atrial septal defects (F-ASDs) in the pediatric population pose a challenge for transcatheter device closure since multiple devices are not preferred in small hearts. Oversizing the Amplatzer Septal Occluder (ASO) to cover the surrounding fenestrations usually distorts the central waist as well as the disc profile and often defeats the purpose. This is a retrospective observational study with an aim to assess the feasibility and safety of cribriform ASO in closing F-ASDs in small children. Read More

Extracochlear Electrode Insertion in the Petrous Area in Cochlear Implantation.

J Int Adv Otol 2021 May;17(3):275-277

Department of Otolaryngology, Mackay Memorial Hospital, Taipei, Taiwan;Department of Audiology and Speech Language Pathology, Mackay Medical College, Taipei, Taiwan.

Cochlear implantation is a reliable and safe tool to rehabilitate patients with severe-to-profound sensorineural hearing loss, who get limited benefits from traditional hearing aids. Electrode misplacement is a rare but significant problem that fails to provide benefits and may cause injury to the nearby structures. We present a case that underwent mastoidectomy first to remove cholesteatoma, followed by cochlear implantation with electrode misplacement into the petrous area, with sustained hearing benefits and without any injury to the surrounding structures.
