A Review of Meta-Analyses in Plastic Surgery: Need for Adequate Assessment of Publication Bias.

INTRODUCTION: Publication bias describes a phenomenon in which significant positive results have a higher likelihood of being published compared to negative or nonsignificant results. Publication bias can confound the estimated therapeutic effect in meta-analyses and needs to be adequately assessed in the surgical literature. METHODS: A review of meta-analyses published in five plastic surgery journals from 2002 to 2022 was conducted. The inclusion criteria for meta-analyses were factors that demonstrated an obligation to assess publication bias, such as interventions with comparable treatment groups and enough power for statistical analysis. Acknowledgment of publication bias risk, quality of bias assessment, methods used in assessment, and individual article factors were analyzed. RESULTS: 318 unique meta-analyses were identified in literature search, and after full-text reviews, 143 met the inclusion criteria for obligation to assess publication bias. 64% of eligible meta-analyses acknowledged the confounding potential of publication bias, and only 46% conducted a formal assessment. Of those who conducted an assessment, 49% used subjective inspection of funnel plots alone, while 47% used any statistical testing in analysis. Overall, only 9/143 (6.3%) assessed publication bias and attempted to correct for its effect. Journals with a higher average impact factor were associated with mention and assessment of publication bias, but more recent publication year and higher number of primary articles analyzed were not. CONCLUSIONS: This review identified low rates of proper publication bias assessment in meta-analyses published in five major plastic surgery journals. Assessment of publication bias using objective statistical testing is necessary to ensure quality literature within surgical disciplines.

Transnasal Endoscopic Approach for Excision of Intracranial Nasal Dermoid Sinus Cysts.

OBJECTIVE: Nasal dermoid sinus cysts (NDSCs) with intracranial extension in the form of dermal sinus tracts require careful and complete resection to prevent recurrence. Resection techniques necessitate adequate intracranial exposure, but morbidity associated with historical resection approaches has presented unique multidisciplinary challenges for surgeons treating cysts with intracranial extension. METHODS: The authors primarily employed a transnasal approach through a midline nasal incision, utilizing endoscopic or microscopic access between the lateral cartilages for resection of NDSCs with intracranial extension. A retrospective review was completed for patients treated for NDSCs at the authors' pediatric quaternary referral center from 2017 to 2023. Data collection included demographics, comorbidities, perioperative data, pre and postoperative imaging, surgical outcomes, and complications. RESULTS: Eighteen patients with NDSCs with possible or confirmed intracranial extension were surgically treated from 2017 to 2023. Fifteen were treated with resection performed through a midline transnasal approach with endoscopic assistance, achieving successful total resection while avoiding nasal osteotomy or frontal craniotomy. One patient had a slow cerebrospinal fluid leak from an operative durotomy, successfully treated with a lumbar drain. No other complications occurred. No patients required transfusion. Incision length and postoperative scar burden were less than approaches that used osteotomies or craniotomies and demonstrated excellent cosmetic results. No patients have had cyst recurrence or required reoperation. CONCLUSIONS: A transnasal approach through a midline incision with endoscopic assistance is an effective approach for resection of NDSC with intracranial extension, but utility may vary with cyst size and complexity. This approach leverages appropriate exposure for resection with decreased morbidity and decreased incision length through avoidance of osteotomies.

Point Blank: A Retrospective Review of Self-inflicted Gunshot Wounds to the Hand.

BACKGROUND: A paucity of literature exists specifically examining self-inflicted (SI) gunshot wounds (GSWs) to the hand and wrist, which impart greater energy and have a higher risk of adverse events than non-self-inflicted (NSI) GSWs. METHODS: We retrospectively reviewed records of patients who presented to our plastic surgery service after sustaining acute GSWs involving the hand and wrist between 2016 and 2018. RESULTS: We identified 60 patients who sustained GSWs involving the hand and wrist; 17 (28%) were SI, and 43 (72%) were NSI. Within the SI group, 100% of patients were Caucasian, with an average age of 54 years. Within the NSI cohort, 77% of patients were Black, 19% were Caucasian, and 4% identified as other. While not statistically significant, we noted a substantial increase in patients requiring operative intervention in the SI cohort (65% SI vs 37% NSI, P = .08). There was a statistically significant increase in patients requiring more than 1 operation in SI patients (24% SI vs 5% NSI, P = .04). Patients who sustained SI injuries were also more likely to present with acute carpal tunnel syndrome requiring urgent surgical release and to develop wound infections (12% vs 0%, P = .08). CONCLUSIONS: Self-inflicted GSWs involving the hand and wrist are associated with greater morbidity than their low-energy NSI counterparts. Individuals presenting with SI GSWs are more likely to be older, to require multiple operations, to develop infections, and to present with acute carpal tunnel syndrome requiring urgent surgical decompression.
