Across 11 RCTs (n=804), periauricular incision reduced transient facial palsy, Frey’s syndrome, earlobe numbness, and facial deformity versus modified Blair incision, with higher patient satisfaction. No differences were found in salivary fistula or operative time; some perioperative metrics favored PI but with high heterogeneity.

Impact: This synthesis of RCTs provides moderate-to-high certainty evidence that PI improves both safety and cosmetic outcomes in superficial benign parotidectomy, informing incision choice. It may standardize practice toward less visible scarring and fewer complications.

Clinical Implications: For small-to-medium benign superficial parotid tumors, consider adopting periauricular incision to reduce facial nerve-related morbidity and improve aesthetic satisfaction. Surgeons should be trained in PI planning to minimize facial contour deformity without increasing fistula risk or operative time.

Key Findings

  • Periauricular incision reduced transient facial palsy (RR 0.60, 95% CI 0.39–0.93).
  • Frey’s syndrome risk was substantially lower with PI (RR 0.27, 95% CI 0.13–0.55).
  • Earlobe numbness (RR 0.53) and facial deformity (RR 0.19) were reduced, and patient satisfaction was higher (RR 1.24).
  • No significant differences in salivary fistula (RR 0.70) or operative time; some perioperative parameters favored PI but with high heterogeneity.

Methodological Strengths

  • PROSPERO-registered protocol with comprehensive multi-database search.
  • Included only randomized controlled trials; risk of bias assessed by RoB 2 and certainty graded by GRADE.

Limitations

  • High heterogeneity for several perioperative outcomes (I² 72–97%).
  • Applicability limited to small-to-medium benign superficial tumors; long-term outcomes variably reported.

Future Directions: Conduct multicenter RCTs with standardized PI techniques, longer follow-up, and patient-reported scar assessments; evaluate applicability to larger tumors and different pathology.

PURPOSE: To compare safety, functional outcomes, and cosmetic results of periauricular incision (PI) versus modified Blair incision (MBI) in superficial benign parotidectomy. METHODS: We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing parotidectomy with PI versus MBI. PubMed, Embase, Web of Science, Cochrane Library, CBM, CNKI, Wanfang, and VIP databases were searched through April 20, 2025 (PROSPERO: CRD42024620827). Outcomes included transient facial palsy, Frey's syndrome, earlobe numbness, facial deformity, patient satisfaction, salivary fistula, operative time, intraoperative blood loss, postoperative drainage, hospital stay, and incision length. The risk of bias was assessed with RoB 2 and evidence certainty was graded by GRADE. RESULTS: Eleven RCTs encompassing 804 patients (PI 401; MBI 403) met the inclusion criteria. Pooled analysis demonstrated that PI significantly reduced transient facial palsy (RR = 0.60, 95 % CI: 0.39-0.93; moderate certainty), Frey's syndrome (RR = 0.27, 95 % CI: 0.13-0.55; high certainty), earlobe numbness (RR = 0.53, 95 % CI: 0.34-0.84; moderate certainty), and facial deformity (RR = 0.19, 95 % CI: 0.08-0.46; high certainty), as well as higher patient satisfaction (RR = 1.24, 95 % CI: 1.16-1.33; moderate certainty). No significant difference was observed in salivary fistula incidence (RR=0.70; 95 % CI, 0.31-1.59; low certainty) and operative time (SMD=-0.29; 95 % CI, -1.30-0.71; very low certainty). Intraoperative bleeding, postoperative drainage, hospitalization length, and incision length favored PI, but evidence quality was downgraded to low/very low due to high heterogeneity (I² = 72-97 %). CONCLUSION: PI appears to be a safe, cosmetically superior alternative to MBI for small-to-medium benign, superficial parotid tumors. Further multicenter, high-quality RCTs with long-term follow-up are warranted to confirm these findings.

In 50 consecutive pT1b PTC patients undergoing TOETVA by a single experienced surgeon, no recurrences occurred over a mean 29.6 months. Temporary mental nerve injury and recurrent laryngeal nerve palsy occurred in 4% each, resolving by 3 months, with high cosmetic satisfaction.

Impact: These data support the oncologic safety and cosmetic advantages of a scarless approach (TOETVA) for pT1b PTC in experienced hands. It informs patient counseling and center selection for remote-access thyroidectomy.

Clinical Implications: TOETVA can be offered to selected pT1b PTC patients at experienced centers, with counseling regarding transient mental nerve dysesthesia and RLN palsy risks. Early oncologic outcomes appear favorable, supporting its use for patients prioritizing cosmesis.

Key Findings

  • No recurrences during mean 29.6 months follow-up (range 2.4–64.4 months).
  • Temporary mental nerve injury 4% and temporary recurrent laryngeal nerve palsy 4%, all resolved within 3 months; no permanent complications.
  • Occult central lymph node metastases in 30% with a mean central node yield of 4.2.
  • High cosmetic satisfaction reported by all patients.

Methodological Strengths

  • Consecutive series with standardized technique by a single experienced endoscopic surgeon.
  • Clear reporting of complications, node yield, and follow-up duration with patient-reported cosmetic outcomes.

Limitations

  • Single-center, single-surgeon cohort without a comparator arm; potential selection bias.
  • Moderate follow-up with predominantly young female patients limits generalizability and long-term oncologic assessment.

Future Directions: Prospective multicenter comparative studies versus open or other remote-access approaches with long-term recurrence, quality of life, and cost-effectiveness endpoints.

OBJECTIVES: Evidence regarding efficacy and oncological safety of Transoral Endoscopic Thyroidectomy Vestibular Approach (TOETVA) for papillary thyroid carcinoma (PTC) with tumor size 1-2 cm remains limited. This study evaluates the surgical and oncological outcomes of TOETVA in patients with pT1b PTC. METHODS: We conducted a cohort study of 50 consecutive patients with pT1b PTC who underwent TOETVA between January 2019 and December 2024 at Our Hospital. Clinical characteristics, surgical outcomes, and long-term oncological results were evaluated. All procedures were performed by a single experienced endoscopic surgeon. Patients were followed for recurrence and complications. RESULTS: The cohort comprised predominantly female patients (96 %) with mean age 30.5 ± 7.1 years. Mean tumor size was 17 ± 4.6 mm. Lobectomy with isthmusectomy and central neck dissection was performed in 44 patients (88 %) with mean operative time of 85.4 ± 7.5 min, while total thyroidectomy with central neck dissection was performed in 6 patients (12 %) with mean operative time of 122.5 ± 5.2 min. Occult central lymph node metastases were identified in 15 patients (30 %). Mean lymph node yield was 4.2 ± 2.2 nodes. Temporary mental nerve injury occurred in 2 patients (4.0 %) and temporary recurrent laryngeal nerve palsy in 2 patients (4.0 %), all resolving within 3 months. No permanent complications were observed. During mean follow-up of 29.6 months (range 2.4-64.4), no recurrences were detected, and all patients reported satisfactory cosmetic outcomes. CONCLUSIONS: TOETVA represents a safe and effective approach for managing pT1b PTC, demonstrating excellent surgical outcomes and patient satisfaction with minimal complications.

In NHANES data on 3,072 women, non-Hispanic Black women had the lowest BP3 levels, while several other racial/ethnic groups had higher levels, which further increased with body dissatisfaction. The moderating effect persisted after adjusting for sunscreen use, suggesting other personal care/consumer products drive exposure.

Impact: This study reveals a psychosocial driver (body dissatisfaction) that amplifies racial disparities in chemical exposures from personal care products. It informs exposure risk assessment and equity-focused regulatory strategies.

Clinical Implications: Clinicians should consider counseling on safer product choices and exposure reduction, particularly for minority women with body dissatisfaction. Public health initiatives can target non-sunscreen personal care products containing BP3 as potential exposure sources.

Key Findings

  • Compared to non-Hispanic Black women, BP3 levels were higher in Mexican American (59%), Other Hispanic (56%), Other Race (33%), non-Hispanic White (16%), and non-Hispanic Asian (9%) women.
  • Body dissatisfaction amplified racial disparities; e.g., Other Hispanic women perceiving themselves as overweight had 69% higher BP3 vs non-Hispanic Black women (p=0.01).
  • Within-group effects: Other Hispanic women with overweight perception had 73% higher BP3 than those without (p=0.03); differences were minimal in non-Hispanic White women (-0.5%, p=0.98).
  • Associations persisted after adjusting for sunscreen use, suggesting other personal care/consumer products contribute to exposure.

Methodological Strengths

  • Large, nationally representative NHANES sample with multi-cycle data.
  • Adjusted models for key confounders and stratified analyses by race/ethnicity.

Limitations

  • Cross-sectional design limits causal inference; body dissatisfaction measured by self-reported weight perception.
  • Single spot urine for BP3 with temporal variability; detailed product use data not captured.

Future Directions: Prospective studies integrating product diaries and biomonitoring to test interventions that reduce BP3 and other EDC exposures among high-risk groups.

BACKGROUND: Body dissatisfaction can drive individuals to use personal care products, exposing themselves to Benzophenone-3 (BP3). Yet, no study has examined the link between body dissatisfaction and elevated chemical exposures. OBJECTIVES: Our study examines how body dissatisfaction impacts the racial differences in BP3 exposures. METHODS: Using NHANES 2003-2016 data for 3,072 women, we ascertained body dissatisfaction with a questionnaire on weight perception. We ran two generalized linear models with log10-transformed urinary concentrations of BP3 as the outcome variable and the following main predictors: one with race/ethnicity and another combining race/ethnicity and body dissatisfaction. We also conducted stratified analyses by race/ethnicity. We adjusted for poverty income ratio, BMI, urinary creatinine, and sunscreen usage. RESULTS: BP3 levels in Mexican American, Other Hispanic, Other Race, non-Hispanic White, and non-Hispanic Asian women were on average 59 %, 56 %, 33 %, 16 %, and 9 % higher, respectively, compared to non-Hispanic Black women. Racial differences in BP3 levels are further widen with body dissatisfaction. For example, Other Hispanic women perceiving themselves as overweight had 69 % higher BP3 levels than non-Hispanic Black women (p-value = 0.01), while those perceiving themselves as at the right weight had 32 % higher levels (p-value = 0.31). Moreover, minority women perceiving themselves as overweight tended to have higher BP3 levels than those who do not. For example, BP3 levels in Other Hispanic women perceiving themselves as overweight are significantly higher compared to those who do not (73 %, p-value = 0.03). In contrast, such differences in the non-Hispanic White women are minimal (-0.5 %, p-value = 0.98). DISCUSSION: Minority women with body dissatisfaction show elevated BP3 exposure independent of sunscreen usage, implying that their elevated exposures may stem from using other personal care and consumer products. Further research is needed to determine if increased exposure to other toxicants occur among minority women with body dissatisfaction.
