Measuring the cochlea: comparison between otoplan and curved multiplanar reconstruction and literature review.
Objectives: To compare two high-resolution computerised tomography based pre-surgical planning software in measuring the cochlear dimensions, which can aid in designing/choosing customised cochlear implant electrodes.
Methods: A cross-sectional-observational study was conducted in a tertiary care centre using high-resolution computerised tomography-supported software Otoplan and curved multi-planar reconstruction to find cochlear duct length's maximum and minimum width/diameter and height in 110 ears (55 subjects). Measurements and the time taken by both techniques were compared.
Results: There were no significant differences in the measurements taken with the two software; however, the time taken for analysis was significantly higher for curved multi-planar reconstruction than with Otoplan.
Conclusion: The steep learning curve, the need for an expert radiologist and the difficulty of use are factors that significantly limit the use of curved multi-planar reconstruction. Otoplan requires less time and can be operated even by someone with less expertise in measuring cochlear dimensions for pre-surgical planning and research.
期刊介绍：
The Journal of Laryngology & Otology (JLO) is a leading, monthly journal containing original scientific articles and clinical records in otology, rhinology, laryngology and related specialties. Founded in 1887, JLO is absorbing reading for ENT specialists and trainees. The journal has an international outlook with contributions from around the world, relevant to all specialists in this area regardless of the country in which they practise. JLO contains main articles (original, review and historical), case reports and short reports as well as radiology, pathology or oncology in focus, a selection of abstracts, book reviews, letters to the editor, general notes and calendar, operative surgery techniques, and occasional supplements. It is fully illustrated and has become a definitive reference source in this fast-moving subject area. Published monthly an annual subscription is excellent value for money. Included in the subscription is access to the JLO interactive web site with searchable abstract database of the journal archive back to 1887.
