As an otolaryngology clinician, Oghalai has treated patients with issues that include noise-induced hearing loss, benign paroxysmal positional vertigo (BPPV), Bell’s palsy and Ramsay Hunt Syndrome.{{cite magazine |last1=Mier |first1=Tomás |title=Justin Bieber's Facial Paralysis Could Take 'Months' to Heal, Experts Say |url=https://www.rollingstone.com/music/music-news/justin-bieber-facial-paralysis-ramsay-hunt-syndrome-experts-1366507/ |access-date=13 January 2023 |magazine=Rolling Stone |date=10 June 2022}} In addition, Oghalai treated rare diseases such as cholesteatoma.{{cite journal| author=Kuo CL, Lien CF, Shiao AS| title=Mastoid obliteration for pediatric suppurative cholesteatoma: long-term safety and sustained effectiveness after 30 years' experience with cartilage obliteration. | journal=Audiol Neurootol | year= 2014 | volume= 19 | issue= 6 | pages= 358–69 | pmid=25377728 | doi=10.1159/000363685 | pmc= | s2cid=30283836 | url=https://pubmed.ncbi.nlm.nih.gov/25377728 }}{{cite journal| author=Egilmez OK, Hanege FM, Kalcioglu MT, Kaner T, Kokten N| title=Tegmen tympani defect and brain herniation secondary to mastoid surgery: case presentation. | journal=Case Rep Otolaryngol | year= 2014 | volume= 2014 | issue= | pages= 756280 | pmid=25140266 | doi=10.1155/2014/756280 | pmc=4129166 | doi-access=free }}{{cite journal| author=McMurphy AB, Oghalai JS| title=Repair of iatrogenic temporal lobe encephalocele after canal wall down mastoidectomy in the presence of active cholesteatoma. | journal=Otol Neurotol | year= 2005 | volume= 26 | issue= 4 | pages= 587–94 | pmid=16015151 | doi=10.1097/01.mao.0000178119.46290.e1 | pmc= | s2cid=37589021 | url=https://pubmed.ncbi.nlm.nih.gov/16015151 }}

Research

In a 2000 study, Oghalai and colleagues examined incidence of benign paroxysmal positional vertigo (BPPV) in geriatric patients at a Houston hospital. They found that 9% of the sample population had undiagnosed BPPV, a predictor of fall risk, depression, and difficulties with daily activities.{{cite journal |last1=Laurent |first1=G |last2=Vereeck |first2=L |last3=Verbecque |first3=E |last4=Herssens |first4=N |last5=Casters |first5=L |last6=Spildooren |first6=J |title=Effect of age on treatment outcomes in benign paroxysmal positional vertigo: A systematic review |journal=Journal of the American Geriatrics Society |date=2022 |volume=70 |issue=1 |pages=281–293 |doi=10.1111/jgs.17485|pmid=34698378 |s2cid=239888032 |doi-access=free |hdl=1942/35743 |hdl-access=free }}{{cite journal |last1=Oghalai |first1=JS |last2=Manolidis |first2=S |last3=Barth |first3=JL |last4=Stewart |first4=MG |last5=Jenkins |first5=HA |title=Unrecognized Benign Paroxysmal Positional Vertigo in Elderly Patients |journal=Otolaryngology–Head and Neck Surgery |date=2000 |volume=122 |issue=5 |pages=630–634 |doi=10.1016/S0194-5998(00)70187-2|pmid=10793337 |s2cid=33401924 }}

To help understand mechanisms of hearing loss brought on by explosive pressures such as those soldiers experience when exposed to roadside bombs, in 2013 Oghalai and his team studied blast effects on hearing in mice. They found that the main traumatic damage leading to noise-induced hearing loss was to cochlear hair and nerve cells,{{cite journal |last1=Kindt |first1=Katie S |last2=Sheets |first2=Lavinia |title=Transmission Disrupted: Modeling Auditory Synaptopathy in Zebrafish |journal=Frontiers in Cell and Developmental Biology |date=2018 |volume=6 |page=114 |doi=10.3389/fcell.2018.00114 |pmid=30258843 |pmc=6143809 |doi-access=free }} the cells responsible for translating pressure waves into the nerve signals in hearing.{{cite journal |last1=Cho |first1=Sung-Il |last2=Simon |first2=S.

In 2018, Oghalai and colleagues studied molecular dimensions of noise-induced hearing loss in mice by using optical coherence tomography, an imaging technique that allows in vivo (instead of invasive) observation and measurement. They found that after blasts damage hair cells, there is also a build up of ionized potassium in cochlear fluid. The findings showed how high concentrations of potassium disrupts hair and nerve cells, whose degeneration or synaptopathy contributes to hearing loss.{{cite journal |last1=Zhao |first1=H |last2=Zhu |first2=Y |last3=Liu |first3=L |title=Excess extracellular K+ causes inner hair cell ribbon synapse degeneration |journal=Communications Biology |date=2021 |volume=4 |issue=1 |page=24 |doi=10.1038/s42003-020-01532-w|pmid=33398038 |pmc=7782724 }}{{cite news |last1=Houser |first1=Kristin |title=An Injection Of Salt In Your Eardrum Might Save You From A Lifetime Of Hearing Loss |url=https://futurism.com/neoscope/nihl-hearing-treatment-salt-eardrum |access-date=13 January 2023 |work=Futurism |date=14 May 2018}}{{cite journal |last1=Kim |first1=J |last2=Xia |first2=A |last3=Grillet |first3=N |last4=Applegate |first4=B.E. |last5=Oghalai |first5=J.S. |title=Osmotic stabilization prevents cochlear synaptopathy after blast trauma |journal=Proceedings of the National Academy of Sciences |date=2018 |volume=115 |issue=21 |pages=E4853–E4860 |doi=10.1073/pnas.1720121115 |pmid=29735658 |pmc=6003510 |doi-access=free }}

In 2022 Oghalai and colleagues published results for a longitudinal study on the effects of cochlear implants on deaf children with developmental delays. They compared cohorts of children who received the implants to a cohort of children who, due to insurance protocols, were only given hearing aids. The children who received implants showed improved cognitive and behavioral functioning.{{cite news |last1=Black |first1=Lisa |title=Study Finds Benefits for Deaf Children With Developmental Delays Who Receive Cochlear Implants |url=https://www.aap.org/en/news-room/news-releases/pediatrics2/2022/study-finds-benefits-for-deaf-children-with-developmental-delays-who-receive-cochlear-implants/ |access-date=23 January 2023 |work=AAP News |publisher=American Academy of Pediatrics |date=24 May 2022}}{{cite news |last1=Katie |first1=Hobbins |title=Cochlear implants benefit children with hearing loss and developmental delays, says study |url=https://www.contemporarypediatrics.com/view/cochlear-implants-benefit-children-with-hearing-loss-developmental-delays |access-date=18 January 2023 |work=Contemporary Pediatrics |date=25 May 2022}}
