Systematic review of submental artery island flap versus free flap in head and neck reconstruction.

PURPOSE: The aim of this systematic review is to compare the perioperative characteristics and outcomes of submental artery island flap (SAIF) to free tissue transfer (FTT) in head and neck reconstruction. MATERIALS AND METHODS: Screening and data extraction were done with Pubmed, Embase, and Web of Science databases by two independent authors to identify randomized and observational studies that compared patient outcomes for SAIF vs. FTT for reconstruction head and neck cancer ablative surgery. Data were pooled with random-effects meta-analysis to determine pooled difference in means (DM), absolute risk differences, and 95% confidence intervals (CI). Heterogeneity was assessed with the I-squared statistic. RESULTS: Initial query yielded 997 results, of which 7 studies met inclusion criteria. The pooled sample sizes for the SAIF and FTT cohorts were 155 and 198, respectively. SAIF reduced mean operative time by 193 min (95% CI -160 to -227), reduced hospital stay by 2.1 days (95% CI -0.9 to -3.4), and had a smaller flap area of 22.5cm2 (95% CI 6.5 to 38.4). SAIF had a 5% higher incidence of partial flap necrosis than FTT (95% CI, 1 to 10), but all other perioperative complications, including recurrence rate in malignant cases, were statistically comparable. CONCLUSIONS: The SAIF requires less operative time, hospital stay, and has comparable perioperative outcomes to FTT, but the area of flap harvest is significantly smaller. The findings of this study add to the growing body of evidence demonstrating the safety and reliability of SAIF in head and neck reconstruction.

Parotidectomy via Individualized Mini-Blair Incision.

BACKGROUND: The modified Blair incision is the standard facial incision for the vast majority of parotid gland lesions. We utilize three types of incisions: "classic mini-Blair" for parotid body tumors, "cervical mini-Blair" for parotid tail tumors, and "vertical mini-Blair" for anterior parotid tumors. In this study, we describe the surgical and esthetic outcomes of these individually tailored incisions. METHODS: Patients undergoing parotidectomy between 2011 and 2013 were included. The surgical outcomes and patients' satisfaction were assessed. RESULTS: Of 122 patients, 89 were included. All patients completed a questionnaire assessing the postoperative course and patients' satisfaction regarding the surgery in general and the scar in particular. Among these patients, 78 (87%) had a benign pathology and 11 (13%) had malignant tumors. The tumors were located at the parotid body in 57 patients (64%), at the parotid tail in 19 (21%), at the deep lobe in 8 (9%), and at the anterior parotid gland in 5 (6%). All tumors were removed successfully with negative margins on pathology. No inadvertent permanent facial nerve paralysis occurred. The median operation time was 72 min (23-211). The average patient scores of satisfaction with the surgical scar and with the surgery were 9.54 and 9.72, respectively. CONCLUSIONS: Individualized mini-Blair incision is feasible for benign as well as selected malignant parotid tumors.

The role of F18-fluorocholine positron emission tomography/magnetic resonance imaging in localizing parathyroid adenomas.

PURPOSE: Preoperative localization of a parathyroid adenoma is usually obtained by the combination of ultrasound and scintigraphy with technetium-99m methoxyisobutylisonitrile. We evaluated the role of F18-fluorocholine in neck positron emission tomography/magnetic resonance imaging as a novel tool for localizing parathyroid adenomas. METHODS: Patients with primary hyperparathyroidism were recruited from February 2016 to August 2017 and F18-fluorocholine positron emission tomography/magnetic resonance imaging was performed to localize the parathyroid adenoma prior to surgery. We compared sensitivity and accuracy of this modality with ultrasound and technetium-99m methoxyisobutylisonitrile scintigraphy using the verified location of the diseased parathyroid as found in surgery. RESULTS: Nineteen patients were included in our study (15 women and 4 men, mean age 60.5 ± 9.8 years). Positron emission tomography/magnetic resonance imaging precisely localized the pathologic parathyroid gland in 16/19 cases (84.2%) and predicted the diseased side in 19/19 cases (100%). Ultrasound and technetium 99 m methoxyisobutylisonitrile sestamibi scintigraphy predicted the location of the parathyroid adenoma in 16/19 (84.2%) and 14/19 (74%), respectively. In 3/19 patients, positron emission tomography/magnetic resonance imaging localized the parathyroid adenoma where as other modalities failed. Positron emission tomography/magnetic resonance imaging was more accurate when compared to each modality separately (p < 0.001, p = 0.017), however, when comparing the three modalities all together no differences were found (p = 0.506). CONCLUSIONS: Localizing parathyroid adenomas with F18-fluorocholine positron emission tomography/magnetic resonance imaging may be a promising secondary imaging modality.

Combined Transcervical and Median Sternotomy Approach for a Massive Substernal Goiter.

Herein, we describe a combined transcervical and median sternotomy approach for a massive substernal goiter causing tracheal stenosis. A goiter of this size, specifically weighing 630 g, is rare. We advocate for a multidisciplinary approach for airway management and for consideration of awake fiberoptic intubation with tracheosomy avoidance for similar patients.

Complications, Mortality, and Functional Decline in Patients 80 Years or Older Undergoing Major Head and Neck Ablation and Reconstruction.

Importance: Data regarding outcomes after major head and neck ablation and reconstruction in the growing geriatric population (specifically ≥80 years of age) are limited. Such information would be extremely valuable in preoperative discussions with elderly patients about their surgical risks and expected functional outcomes. Objectives: To identify patient and surgical factors associated with 30-day postoperative complications, 90-day mortality, and 90-day functional decline; to explore whether an association exists between the type of reconstructive procedure and outcome; and to create a preoperative risk stratification system for these outcomes. Design, Setting, and Participants: This retrospective, multi-institutional cohort study included patients 80 years or older undergoing pedicle or free-flap reconstruction after an ablative head and neck surgery from January 1, 2015, to December 31, 2017, at 17 academic centers. Data were analyzed from February 1 through April 20, 2019. Main Outcomes and Measures: Thirty-day serious complication rate, 90-day mortality, and 90-day decline in functional status. Preoperative comorbidity and frailty were assessed using the American Society of Anesthesiologists classification, Adult Comorbidity Evaluation-27 score, and Modified Frailty Index. Multivariable clustered logistic regressions were performed. Conjunctive consolidation was used to create a risk stratification system. Results: Among 376 patients included in the analysis (253 [67.3%] men), 281 (74.7%) underwent free-flap reconstruction. The median age was 83 years (range, 80-98 years). A total of 193 patients (51.3%) had 30-day serious complications, 30 (8.0%) died within 90 days, and 36 of those not dependent at baseline declined to dependent status (11.0%). Type of flap (free vs pedicle, bone vs no bone) was not associated with these outcomes. Variables associated with worse outcomes were age of at least 85 years (odds ratio [OR] for 90-day mortality, 1.19 [95% CI 1.14-1.26]), moderate or severe comorbidities (OR for 30-day complications, 1.80 [95% CI, 1.34-2.41]; OR for 90-day mortality, 3.33 [95% CI, 1.29-8.60]), body mass index (BMI) of less than 25 (OR for 30-day complications, 0.95 [95% CI, 0.91-0.99]), high frailty (OR for 30-day complications, 1.72 [95% CI, 1.10-2.67]), duration of surgery (OR for 90-day functional decline, 2.94 [95% CI, 1.81-4.79]), flap failure (OR for 90-day mortality, 3.56 [95% CI, 1.47-8.62]), additional operations (OR for 30-day complications, 5.40 [95% CI, 3.09-9.43]; OR for 90-day functional decline, 2.94 [95% CI, 1.81-4.79]), and surgery of the maxilla, oral cavity, or oropharynx (OR for 90-day functional decline, 2.51 [95% CI, 1.30-4.85]). Age, BMI, comorbidity, and frailty were consolidated into a novel 3-tier risk classification system. Conclusions and Relevance: Important demographic, clinical, and surgical characteristics were found to be associated with postoperative complications, mortality, and functional decline in patients 80 years or older undergoing major head and neck surgery. Free flap and bony reconstruction were not independently associated with worse outcomes. A novel risk stratification system is presented.
