Characterization of the human helicotrema: implications for cochlear duct length and frequency mapping.
Helpard L, Li H, Rask-Andersen H, Ladak HM, Agrawal SK. Helpard L, et al. J Otolaryngol Head Neck Surg. 2020 Jan 6;49(1):2. doi: 10.1186/s40463-019-0398-8. J Otolaryngol Head Neck Surg. 2020. PMID: 31907040 Free PMC article.
Synchrotron radiation phase-contrast imaging has made this analysis possible due to the soft-tissue contrast through the entire cochlear apex. METHODS: Helicotrema linear length and helicotrema angular length measurements were performed on synchrotron radiation phas …

The effect of the helicotrema on low-frequency loudness perception.
Jurado C, Marquardt T. Jurado C, et al. J Acoust Soc Am. 2016 Nov;140(5):3799. doi: 10.1121/1.4967295. J Acoust Soc Am. 2016. PMID: 27908034
Below approximately 40 Hz, the cochlear travelling wave reaches the apex, and differential pressure is shunted through the helicotrema, reducing hearing sensitivity. Just above this corner frequency, a resonance feature is often observed in objectively measured middle-ear- …

[Scanning electron microscopic findings concerning the formation of the organ of Corti near the helicotrema in guinea pigs].
Linss W, Linss V, Emmerich E, Richter F. Linss W, et al. Ann Anat. 2000 Sep;182(5):445-9. doi: 10.1016/s0940-9602(00)80051-5. Ann Anat. 2000. PMID: 11035640 German.
At the apical end of the Corti organ only in the inner row of hair cells the stereociliae are detectable by scanning electron microscopy. Here the row is interrupted several times. Near the helicotrema we find first the inner row of the outer hair cells, then the middle ro …

Infrasonic hearing in birds: a review of audiometry and hypothesized structure-function relationships.
Zeyl JN, den Ouden O, Köppl C, Assink J, Christensen-Dalsgaard J, Patrick SC, Clusella-Trullas S. Zeyl JN, et al. Biol Rev Camb Philos Soc. 2020 Aug;95(4):1036-1054. doi: 10.1111/brv.12596. Epub 2020 Mar 31. Biol Rev Camb Philos Soc. 2020. PMID: 32237036 Review.
In the middle ear, this could be achieved by large air cavities in the skull connected to the middle ear and low stiffness of middle ear structures; in the inner ear, the stiffness of round windows and cochlear partitions are key factors. Within the inner ear, the sizes of the …

Old theme and new reflections: hearing impairment associated with endolymphatic hydrops.
Horner KC. Horner KC. Hear Res. 1991 Mar;52(1):147-56. doi: 10.1016/0378-5955(91)90194-e. Hear Res. 1991. PMID: 2061203 Review.
The higher K+ concentration arriving from the scala vestibuli into the scala tympani at the apex of the cochlea via the helicotrema is likely to be toxic to hair cell and auditory nerve fiber function. ...

Effect of Return Electrode Placement at Apical Cochleostomy on Current Flow With a Cochlear Implant.
Landsberger DM, Long CJ, Kirk JR, Stupak N, Roland JT Jr. Landsberger DM, et al. Ear Hear. 2024 Mar-Apr 01;45(2):511-516. doi: 10.1097/AUD.0000000000001439. Epub 2023 Dec 4. Ear Hear. 2024. PMID: 38047764
One objective is to verify a suitable approach for implanting ECE1 in the helicotrema. Another is to determine how placement of ECE1 reshapes electric fields. ...Changes in electric fields were only observed when ECE1 was placed into the fluid in the helicotrema. Wh …

Stimulating the Cochlear Apex Without Longer Electrodes: Preliminary Results With a New Approach.
Landsberger DM, Stupak N, Spitzer ER, Entwisle L, Mahoney L, Waltzman SB, McMenomey S, Friedmann DR, Svirsky MA, Shapiro W, Roland JT Jr. Landsberger DM, et al. Otol Neurotol. 2022 Jun 1;43(5):e578-e581. doi: 10.1097/MAO.0000000000003529. Epub 2022 Mar 10. Otol Neurotol. 2022. PMID: 35283466 Free PMC article.
The surgery differed from the standard approach in that a ground electrode was placed in the cochlear helicotrema via an apical cochleostomy rather than in its typical location underneath the temporalis muscle. ...

Low-frequency neural and cochlear-microphonic tuning curves in the gerbil.
Schmiedt RA, Zwislocki JJ. Schmiedt RA, et al. J Acoust Soc Am. 1978 Aug;64(2):502-7. doi: 10.1121/1.382000. J Acoust Soc Am. 1978. PMID: 712012
CM tuning at the most apical electrode position is sharper than expected for frequencies below the best frequency--a result that may be due to the shunting effect of the helicotrema at low frequencies- Previous modeling results have confirmed that apical basilar-membrane t …

Interplay between traveling wave propagation and amplification at the apex of the mouse cochlea.
Nankali A, Shera CA, Applegate BE, Oghalai JS. Nankali A, et al. Biophys J. 2022 Aug 2;121(15):2940-2951. doi: 10.1016/j.bpj.2022.06.029. Epub 2022 Jun 30. Biophys J. 2022. PMID: 35778839 Free PMC article.
The phase velocity was larger than the group velocity, and both quantities gradually decrease from the base to the apex denoting a strong dispersion characteristic near the helicotrema. Moreover, we found that the spatial wavelength along the BM was highly level dependent …
