Abstract
INTRODUCTION Unilateral vocal fold paralysis or paresis (UVFP) is a condition that causes significant morbidity due to dysphonia, dysphagia, and aspiration. Type I medialization thyroplasty (MT) is the current mainstay surgical treatment for UVFP. Though widely considered a safe procedure, concerns exist over possible airway complications which can lead to overnight observation. Herein, we report a systematic review of the safety and adverse events of MT to aid in determining the safety of same-day discharge. DATA SOURCES PubMed and Embase databases. REVIEW METHODS Our search identified studies investigating complications associated with MT. Articles were selected if published between January 1, 1989 and March 15, 2023. Abstracts were screened, and data were extracted from included studies. Only Type I MT procedures were included; case reports were excluded. Participant characteristics, intervention details, results, and adverse events were extracted. RESULTS The database query identified 751 abstracts, of which 46 studies met eligibility criteria. A total of 2426 patients underwent MT. The most common implant was Silastic (n = 898, 37.0%) followed by Gore-Tex (n = 664, 27.4%). There were 254 (10.5%) total complications reported; 110 (4.5%) were considered major. The most common complication was nonobstructive hematoma (n = 59, 2.4%) followed by hemorrhage (n = 36, 1.5%). Implant extrusion (n = 24, 0.99%) or displacement (n = 15, 0.62%) occurred mostly in Silastic and Gore-Tex implants. Same-day discharge occurred with 429 patients and was not associated with adverse events. CONCLUSIONS UVFP can be reliably improved by MT with a low risk of complications. Outpatient MT is a promising treatment with a favorable safety profile. Laryngoscope, 134:1994-2004, 2024.

Eur Arch Otorhinolaryngol 2023; 280:5011-5017. [PMID: 37584751 PMCID: PMC10756884 DOI: 10.1007/s00405-023-08165-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Accepted: 07/28/2023] [Indexed: 08/17/2023]
Abstract
PURPOSE Laryngeal framework surgery, including medialization laryngoplasty and arytenoid adduction (AA), is expected to have a lasting or permanent effect in patients with unilateral vocal fold paralysis (UVFP); however, there are few reports about the long-term outcomes of AA. This study aimed to evaluate the long-term postoperative effects of AA surgery and examine its stability and reliability. METHODS This study collected the voice handicap index (VHI) questionnaire from patients with UVFP who underwent AA more than 2 years previously. The VHI values preoperatively and 3 months postoperatively (early postoperative evaluation) were retrospectively calculated, and VHI values more than 2 years after surgery (late postoperative evaluation) were collected by mailing a sheet to the patients and asking to fill and return it. Possible influenced subscales such as age, sex, causes of UVFP, affected side, and surgeons were also analyzed. RESULTS A total of 77 patients with UVFP who underwent AA had significantly lower early and late postoperative evaluations than preoperative evaluations. In 38 patients with no missing values, there were no significant differences between early and late postoperative evaluations, measured at a median of approximately 5 years. There were also no significant differences between early and late postoperative evaluations in any of the subscale groups. CONCLUSION Patients with UVFP who underwent AA surgery achieved stable voice improvement in the long term after surgery.

Abstract
Postoperative intrauterine adhesion (IUA), caused by endometrial basal layer injury, is one of the main causes of female infertility. The excessive deposition of fibrin as well as fibroblast is considered the root cause of IUA. However, few clinical strategies are effective in preventing extracellular matrix (ECM) deposition at endometrial wounds that include protein and cell deposits. Herein, the injectable granular poly(N-(2-hydroxyethyl) acrylamide) (PHEAA) hydrogel (granular PHEAA gel), which presents excellent antifouling properties and remarkably prevents protein and cell adhesions, is used to prevent postoperative IUA. The granular PHEAA gel with a jammed network structure exhibits outstanding injectability and superior stability. Compared with the IUA group, the granular PHEAA gel can promote regeneration of the endometrium while reducing the area of endometrial fibrosis. Immunohistochemical staining experiments indicate that the granular PHEAA gel can improve the proliferation of the endometrium, promote vascularization, and enhance anti-inflammatory effect in IUA rats. And the granular PHEAA gel can effectively slow down the fibrosis of uterine tissue. Importantly, the number of embryos is significantly increased after injecting granular PHEAA gel, inferring that there is an obvious reproductive function recovery of injured endometrium.

Long-term voice outcomes of laryngeal framework surgery for unilateral vocal fold paralysis. Eur Arch Otorhinolaryngol 2021; 279:1957-1965. [PMID: 34787700 DOI: 10.1007/s00405-021-07177-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2021] [Accepted: 11/03/2021] [Indexed: 10/19/2022]
Abstract
OBJECTIVE To evaluate the short- and long-term voice outcomes after unilateral medialization thyroplasty (MT) and unilateral medialization thyroplasty with arytenoid adduction (MT + AA) in patients with unilateral vocal fold paralysis. METHODS Voice outcomes were assessed preoperatively, and postoperatively at 3 and 12 months according to a standardized protocol. Voice assessment was performed using Voice Handicap Index (VHI), GRBAS Grade, Maximum Phonation Time (MPT), s/z-ratio and subjective numeric rating scales on voice quality, effort, performance and influence on life. RESULTS Sixty-one patients were included (34 MT and 27 MT + AA). Significant pre- to postoperative improvements were seen in all voice outcome parameters. No significant differences in post-operative values were identified between the groups. CONCLUSION Based on our findings, we conclude that patients with unilateral vocal fold paralysis who undergo MT and MT + AA achieve comparable and significant long time voice improvement, although voices do not completely normalize. We also conclude that this does not mean that AA is a superfluous procedure, but can indicate the accurate identification of patients in need of the additional AA procedure based on clinical parameters.

Laryngoscope 2021; 132:1414-1420. [PMID: 34726793 DOI: 10.1002/lary.29921] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 09/22/2021] [Accepted: 10/15/2021] [Indexed: 11/06/2022]
Abstract
OBJECTIVES/HYPOTHESIS To characterize and identify predictors of 30-day adverse events in patients undergoing laryngeal framework surgery (LFS). STUDY DESIGN This study is a retrospective analysis of the National Surgical Quality Improvement dataset. METHODS LFS cases were identified from the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database from 2008 to 2018. Demographic variables, patient comorbidities, and perioperative outcomes (any adverse event, 30-day readmission, 30-day reoperation, and unplanned intubation) were extracted. Patient-specific and surgery-specific factors associated with perioperative adverse events were examined using descriptive statistics and univariate logistic regression (LR). RESULTS Of 283 patients who underwent LFS, 225 underwent laryngoplasty medialization, 56 underwent laryngoplasty medialization with arytenoidectomy or arytenoidopexy via an external approach, and 2 underwent local myocutaneous or fasciocutaneous advancement flap along with laryngoplasty. Medical comorbidities were present in 33.6% of patients and 57.9% were American Society of Anesthesiologists (ASA) Class III/IV (57.9%). LFS was performed as same-day surgery in 30.7% of cases. Fourteen patients (4.9%) suffered an adverse condition within 30 days following surgery. In univariate LR, ASA Class III or IV (odds ratio [OR] 4.6, 95% confidence interval [CI] 1.2-30.1) was the only predictor associated with any adverse event. Arytenoid adduction (AA) was associated with increased risk of reoperation within 30 days of the initial surgery (OR 6.4, 95% CI 1.0-49). CONCLUSIONS LFS is a generally safe procedure with infrequent perioperative adverse events. In the ACS-NSQIP database, ASA classification of III or IV was associated with a higher risk for any 30-day adverse event and AA was associated with a higher risk for 30-day reoperation.
