Two Consecutive Cases of Persistent Stapedial Artery Managed With a Carbon Dioxide Laser

Abstract

A CO laser can be useful for managing a PSA in the setting of chronic ear disease.

Lasers in Cholesteatoma Surgery: A Systematic Review

“…These studies were published between 1997 and 2020 and conducted in America, Asia, and Europe. Four of them were case reports, [8][9][10][11] 5 were retrospective cohort studies, [12][13][14][15][16] and 3 were prospective cohort studies. [17][18][19] Recruited participant numbers ranged from 2 8,11 to 200.…”

“…While laser surgery is thought to facilitate atraumatic dissection of cholesteatoma from mobile ossicles and therefore reducing the risk of trauma to the cochlea from mechanical traction, there has only been one study 18 that compared the outcomes from 2 groups that were treated with laser (patients with ossicular chain intact vs disrupted). The hearing results did not show that using laser surgery improved hearing in Two fistulas were inadvertently perforated, each was closed by a fat graft and then covered by fascia 18 Postoperative cochlear function between ossicular chain intact and disrupted groups were not significant (intact: þ1.5 dB HL, disrupted: À0.6 dB HL) Stevens et al, 2018 11 Hearing results in one case showed some improvement Distorted product otoacoustic emission (DPOE)…”

“…Closure of air-bone gap. Hamilton, 2010 18 Postoperative cochlear function between ossicular chain intact and disrupted groups were not significant (intact: þ1.5 dB HL, disrupted: À0.6 dB HL) Stevens et al, 2018 11 Hearing results in one case showed some improvement Distorted product otoacoustic emission (DPOE)…”

“…As part of their outcome measure, 9 papers 10,11,[13][14][15][16][17][18][19] looked at the presence or absence of residual disease at either a second stage operation, with diffusion-weighted magnetic resonance imaging or computed tomography scan at least 12 months after the first operation or clinical observation. There were 2 papers that had a control group and compared the outcomes of laser versus no laser, while Hamilton in 2005 17 showed that using a laser significantly reduced the chance of residual disease after 12 months, Sharma et al in 2020 19 did not report any significant difference between using the laser or not.…”

“…The other papers report their recurrence rate between 0% and 33%. 10,11,[13][14][15][16]18 Table 5 summarized the disease eradication outcomes.…”
