Mandibular Distraction in Patients With Pierre Robin Sequence: A Multisurgeon Experience.

OBJECTIVE: Mandibular distraction osteogenesis (MDO) is rapidly becoming a standard of care for management of patients with severe Pierre Robin sequence. The tongue is brought forward to alleviate airway obstruction. This study will look at an institutional, multisurgeon experience with MDO over 10 years. DESIGN: A retrospective chart review was conducted. SETTING: All patients who underwent MDO at the authors' institution from 2012 to 2022 were included. Three craniofacial surgeons performed all interventions. PATIENTS: Demographics, preoperative and postoperative respiratory and feeding status, and distraction data were collected for 27 patients meeting inclusion criteria. MAIN OUTCOME MEASURES: Primary outcomes were avoidance of a gastrostomy tube, avoidance of a tracheostomy, discharge from hospital on room air, and complications. A significance value of 0.05 was utilized. RESULTS: The average age at MDO was 135 days, mean activation phase was 13.6 days, mean distraction length was 14.9 mm, and mean consolidation phase was 64.2 days. A longer activation phase was associated with discharge with a gastrostomy tube and a shorter activation phase was associated with discharge on full oral feeds. The ability to discharge on room air was associated with a shorter latency phase, shorter activation phase, and decreased distance of distraction. CONCLUSIONS: The goal of MDO is to achieve full oral feeds with no respiratory support. Several different latency periods were used in this study, and a short latency period was demonstrated to be safe.

Posterior Vault Distraction in the Acute Setting.

ABSTRACT: Posterior vault distraction osteogenesis (PVDO) has been shown to resolve acute intracranial hypertension (AIH) while carrying an acceptable perioperative morbidity profile. PVDO has been associated with symptomatic improvement and fewer surgeries in those requiring ventriculoperitoneal shunts. The authors' experience using PVDO as an acute intervention is presented, demonstrating its safety and efficacy for management of AIH. Four cases of children with craniosynostosis that underwent PVDO in the acute setting are outlined. All patients presented with papilledema and symptoms of AIH. One patient with slit ventricle syndrome (SVS) presented with a nonfunctioning shunt following multiple shunt revisions. No intraoperative complications during distractor placement or removal were reported. Distraction protocol for all patients began on postoperative day 1 at 1-2 mm per day, resulting in an average total distraction of 30.25 mm. For the 3 cases with no shunt, the average length of stay was 7 days. As part of the planned treatment course, the patient with SVS required externalization of the shunt during distraction followed by early distractor removal and planned shunt replacement. One case of surgical site infection (in an immunocompromised patient) required premature distractor removal during the consolidation period. Computed tomography (CT) in all patients indicated increased intracranial volume following distraction, and symptomatic improvement was reported. Six-month follow-up showed resolution of papilledema in all patients. The authors' experience using PVDO in the acute setting is reported, alongside a review of current literature, in order to provide supporting evidence for the efficacy of PVDO as a tool for resolving AIH.

Patients Requiring Multiple Surgeries for Velopharyngeal Insufficiency: Findings From a 10-Year Retrospective Review.

This study analyzed patients undergoing multiple surgeries for velopharyngeal insufficiency (VPI) and reviewed their preoperative evaluations and techniques selected for subsequent surgeries. A retrospective chart review was performed including patients having undergone multiple surgeries for VPI at the authors' institution between 2012 and 2022. All patients were evaluated and managed at the author's institution under the direction of 4 senior surgeons. The objective of this study was to provide insight into preoperative evaluation, surgical technique selection, and other factors that may contribute to patients who require multiple VPI surgeries. Of 71 patients having undergone surgery for VPI, 8 required at least 1 additional operation for persistent VPI following the initial intervention. Six patients who initially underwent a superiorly based posterior pharyngeal flap (PPF) required additional surgery, and for those patients' subsequent operations, 5 different techniques were used throughout their treatment. Of the remaining 2 patients who had multiple VPI surgeries, 1 initially received autologous fat transfer and 1 initially underwent a furlow palatoplasty. Finally, 0 patients that initially underwent buccal flaps or collagen injection required further unplanned surgical intervention. This study demonstrates the importance of selecting an appropriate surgical approach when operating on patients following a failed VPI surgery. The algorithm developed from these findings emphasizes the importance of properly identifying the anatomical deficiency resulting from the failed intervention. A review of the advantages of nasopharyngoscopy as a preoperative evaluative technique of velopharyngeal form and function when compared to lateral barium video fluoroscopy was also included.

A Cost and Metric Comparison of Disposable Negative-Pressure Wound Therapy Systems.

BACKGROUND: Disposable NPWT (dNPWT), a form of negative-pressure wound therapy, has been shown to be both outcome- and cost-effective for small to medium-sized wounds or closed incisions compared to traditional NPWT systems. When choosing a dNPWT system, multiple factors should be evaluated, including the wound size, wound type, estimated exudate production, and required days of therapy. If the device is not optimized for use in a particular patient, a much higher overall cost can be expected. METHODS: A web-based search, manufacturer website review and communication, and list price-based cost analysis was performed for currently available dNPWT systems. These systems differ with respect to cost, degree of negative pressure, canister size, number of dressings included, and recommended days of therapy. RESULTS: The results showed that 3M™ KCI devices (3M™ KCI, St. Paul, MN) cost about 6x more per day than non-KCI devices, and the V.A.C.® Via and Prevena™ Plus Customizable Incision Management System (both 3M KCI) cost over $180 per day of use. The no-canister Pico 14™ (Smith+Nephew, Watford, UK) is the most cost-effective dNPWT option, with an overall cost of $25.00 per day, but is limited to low exudate-producing wounds, such as closed incisions. At $25.67 per day, the UNO 15 (Genadyne Biotechnologies, Hicksville, NY) is the most cost-effective dNPWT option that still includes a replaceable canister system. CONCLUSION: We present a cost and metric comparison of currently available dNPWT systems. Despite significant differences in the cost of treatment with each dNPWT device, there has been limited research on their relative efficacies.
