A Master Mind Game Code Algorithm Approach to Help Surgical Decision-Making between Retropharyngeal Fat Grafting and Pharyngoplasty for the Treatment of Velopharyngeal Incompetence

Abstract Introduction Velopharyngeal insufficiency (VPI) is a controversial pathology with many surgical options. Objectives To compare pharyngoplasty and retropharyngeal fat grafting and to build a prognostic tool to achieve perfect speech. Methods Retrospective observational cohort study of 114 patients operated for VPI from 1982 to 2019 in a single tertiary center. The instrumental assessment was made using an aerophonoscope and nasofibroscopy. The variables sex, age, genetic syndromes, and type of diagnosis were analyzed with logistic regression model adjusted with propensity score. To generalize results and to build a surgical predictive tool, a marginal analysis concludes the study. Results Among the patients (median [range] age 7 [4-48]), 63 (55.26%) underwent pharyngoplasty and 51 (44.74%) graft. The graft group had no complication, but it had a failure rate of 7.84%. The pharyngoplasty group had no failure, but one patient had postoperative obstructive sleep apnea. The marginal analysis demonstrated that age lower than 7 years, cleft lip and palate, absence of syndrome, and intermittent VPI were important predictive factors of good result regardless of surgical technique. Conclusions Without a statistical demonstration of the superiority of pharyngoplasty over graft, and in the uncertainty of literature background, our perfect-speech patient profile represents an important tool for a postoperative forecast of results in which, like in the Master Mind game, every feature has to be considered not individually but as a pattern of characteristics whose association contributes to the outcome.

Pedicled Flaps versus Free Flaps for Oral Cavity Cancer Reconstruction: A Comparison of Complications, Hospital Costs, and Functional Outcomes

Abstract Introduction Free flaps have been the preferred method for reconstruction after resection of oral cavity cancer. However, pedicled flaps remain valuable alternatives in appropriate settings. Objective The main objective of the present study was to compare surgical complications, hospital costs, and functional outcomes of oral cavity cancer patients who underwent soft tissue reconstruction with pedicled flaps or free flaps. Methods A total of 171 patients were included in the study. Ninety-eight underwent reconstruction with a pectoralis major, submental, temporalis, or supraclavicular pedicled flap, and in 73 patients, a radial forearm or anterolateral thigh free flap had been used. The cases were retrospectively reviewed, and a comparative analysis was carried out between the two groups. Results Recipient site and flap complications, speech, and swallowing functions did not differ between groups, but donor site complications, operative time, hospital stay, and costs were significantly reduced in the pedicled flap group compared with the free flap group. However, the pectoralis major flap reconstruction resulted in a more inferior swallowing function than the free flap reconstruction. Conclusions With comparable complications and functional outcomes, while decreasing in costs, pedicled flaps are a useful alternative to free flaps in oral cavity cancer reconstruction. However, in an extensive defect (> 70 cm2), free flaps are the reconstruction of choice for the preservation of swallowing function.

Anastomotic complications after esophagectomy: Influence of omentoplasty in propensity-weighted cohorts.

OBJECTIVE: A recent meta-analysis of 3 randomized controlled trials reported reduced incidence and severity of postesophagectomy anastomotic dehiscence with anastomotic omentoplasty. Unfortunately, these trials excluded neoadjuvant patients who received chemoradiation. We aimed to determine whether anastomotic omentoplasty was associated with differential postesophagectomy anastomotic complications after neoadjuvant chemoradiotherapy. METHODS: Data for patients who underwent minimally invasive esophagectomy following neoadjuvant chemoradiotherapy were abstracted (n = 245; 2001-2016; omentoplasty = 147 [60%]). Propensity for omentoplasty was estimated on 21 pretreatment variables, using augmented inverse probability of treatment weights, and used to determine the adjusted proportion of adverse anastomotic outcomes, major morbidity, and 30-day/in-hospital mortality. RESULTS: Overall, anastomotic leak rate was 15%; leak-associated mortality was 13% (n = 5 out of 37). Leak rates (omentoplasty n = 24 [16%] vs no omentoplasty n = 13 [13%]; P = .512) and incidence of any major complications (48% vs 48%; P = .958) were similar. Leaks requiring surgical intervention occurred in 12 patients (5% vs 5%; P = .904). Propensity weighting achieved excellent balance across all 21 pretreatment variables (before weighting, standardized differences ranged from -0.23 to 0.35; postweighting standardized differences ranged from -0.09 to 0.07). In propensity-weighted data, omentoplasty was not associated with differential adjusted risk of anastomotic leak (13.2% vs 14.3%; P = .83), major morbidity (27.9% vs 32.6%; P = .44), or mortality (6.7% vs 4.8%; P = .61). CONCLUSIONS: Within the limits of our sample size and statistical approach, our study failed to find evidence that anastomotic omentoplasty during esophagectomy after neoadjuvant chemoradiation reduced anastomotic leak rate or need for leak-related reoperation.

Extended Posterior Interosseous Artery Flap: Anatomical and Clinical Study.

PURPOSE: A reverse-flow pedicled flap from the posterior interosseous artery (PIA) has been used to cover defects on the dorsal and volar aspects of the hand. However, the original description of this flap does not reach further than the metacarpophalangeal joints of the 4 ulnar digits. In the present study, we describe a distal variant (type 2) of the PIA flap, which changes the pivot point of the classic variant (type 1) and which can provide full coverage of single or multiple digits in the entire dorsum and palmar surface of the fingers. METHODS: An anatomical study was performed on 26 cadaveric specimens to assess the presence of the anastomosis between the PIA and the dorsal intercarpal arch (DIA). In addition, the gain in pedicle length using the DIA anastomosis as a pivot point was compared with the classic pivot point at the anterior interosseous artery. A clinical study in 19 patients with soft tissue defects distal to the proximal interphalangeal joint of the fingers was also performed to assess the viability and clinical outcomes of the new variant of the PIA flap. RESULTS: The PIA was identified reaching the dorsal carpal arch in all anatomical specimens. The mean pedicle length of the fifth extensor compartment artery was 4.8 cm (range, 4.1-5.3 cm). The mean arterial diameter was 0.8 mm (range, 0.6-1.2 mm). In the clinical study, 17 flap reconstructions were done for posttraumatic lesions and 2 postburn contractures. All extended PIA flap procedures were performed successfully without loss of the flap or significant partial necrosis. We had only 1 superficial infection. There was no need for revision of the flap in any case. CONCLUSIONS: By extending the pivot point of the PIA flap through the DIA, instead of the anastomosis with the anterior interosseous artery, the flap distance can be increased by about 8.5 cm, allowing complete coverage of the fingers. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
