Objective To investigate causes of failure of free flap reconstructions in patients undergoing reconstruction of head and neck defects. Study Design Case series with chart review. Setting Single tertiary care center. Subjects and Methods Patients underwent reconstruction between January 2007 and June 2017 (n = 892). Variables included were clinical characteristics, social history, defect site, donor tissue, ischemia time, and postoperative complications. Statistical methods used include univariable and multivariable analysis of failure. Results The overall failure rate was 4.8% (n = 43). Intraoperative ischemia time was associated with free flap failures (odds ratio [OR], 1.062; 95% confidence interval [CI], 1.019-1.107; P = .004) for each addition of 5 minutes. Free flaps that required pedicle revision at time of initial surgery were 9 times more likely to fail (OR, 9.953; 95% CI, 3.242-27.732; P < .001). Patients who experienced alcohol withdrawal after free flap placement were 3.7 times more likely to experience flap failure (OR, 3.690; 95% CI, 1.141-10.330; P = .031). Ischemia time remained an independent significant risk factor for failure in nonosteocutaneous free flaps (OR, 1.105; 95% CI, 1.031-1.185). Alcohol withdrawal was associated with free flap failure in osteocutaneous reconstructions (OR, 5.046; 95% CI 1.103-19.805) while hypertension was found to be protective (OR, 0.056; 95% CI, 0.000-0.445). Conclusion Prolonged ischemia time, pedicle revision, and alcohol withdrawal were associated with higher rates of flap failure. Employing strategies to minimize ischemic time may have potential to decrease failure rates. Flaps that require pedicle revision and patients with a history of significant alcohol use require closer monitoring.

Objective To determine the frequency at which patients with osteocutaneous free flap reconstruction of the head and neck develop long-term complications and identify predisposing perioperative factors. Study Design A prospectively maintained database of free flaps performed at a single institution over a 10-year period was queried. Setting Single tertiary care referral center. Subjects and Methods In total, 250 osseous or osteocutaneous free flaps (OCFFs) for mandibular or maxillary reconstruction were analyzed. Data were collected on demographics, preoperative therapy, resection location, adjuvant treatment, complications, and subsequent surgeries, and multivariate analysis was performed. Subgroup analysis based on perioperative factors was performed. Results The median follow-up time was 23 months. In 185 patients with at least 6 months of follow-up, 17.3% had at least 1 long-term complication, most commonly wound breakdown, fistula or plate extrusion (13.5%), osteoradionecrosis or nonunion (6.5%), and infected hardware (5.9%). Prior chemoradiotherapy and cancer diagnosis predisposed patients to long-term complications. At the 5-year follow-up, 21.7% of patients had experienced a long-term complication. Conclusions Long-term complications after OCFF occurred in 17% of patients. In this series, a preoperative history of chemoradiation and those undergoing maxillary reconstruction were at high risk for the development of long-term complications and thus warrant diligent follow-up. However, OCFFs can often enjoy long-term viability and survival, even in the case of perioperative complications and salvage surgery.

Objective Analyze the cause and significance of a shift in the timing of free flap failures in head and neck reconstruction. Study Design Retrospective multi‐institutional review of prospectively collected databases at tertiary care centers. Methods Included consecutive patients undergoing free flap reconstructions of head and neck defects between 2007 and 2017. Selected variables: demographics, defect location, donor site, free flap failure cause, social and radiation therapy history. Results Overall free flap failure rate was 4.6% (n = 133). Distribution of donor tissue by flap failure: radial forearm (32%, n = 43), osteocutaneous radial forearm (6%, n = 8), anterior lateral thigh (23%, n = 31), fibula (23%, n = 30), rectus abdominis (4%, n = 5), latissimus (11%, n = 14), scapula (1.5%, n = 2). Forty percent of flap failures occurred in the initial 72 hours following reconstruction (n = 53). The mean postoperative day for flap failure attributed to venous congestion was 4.7 days (95% confidence interval [CI], 2.6–6.7) versus 6.8 days (CI 5.3–8.3) for arterial insufficiency and 16.6 days (CI 11.7–21.5) for infection (P < .001). The majority of flap failures were attributed to compromise of the arterial or venous system (84%, n = 112). Factors found to affect the timing of free flap failure included surgical indication (P = .032), defect location (P = .006), cause of the flap failure (P < .001), and use of an osteocutaneous flap (P = .002). Conclusion This study is the largest to date on late free flap failures with findings suggesting a paradigm shift in the timing of flap failures. Surgical indication, defect site, cause of flap failure, and use of osteocutaneous free flap were found to impact timing of free flap failures. Level of Evidence 4 Laryngoscope, 130:347–353, 2020

Acute auricular hematoma is common after blunt trauma to the side of the head. A network of vessels provides a rich blood supply to the ear, and the ear cartilage receives its nutrients from the overlying perichondrium. Prompt management of hematoma includes drainage and prevention of reaccumulation. If left untreated, an auricular hematoma can result in complications such as perichondritis, infection, and necrosis. Cauliflower ear may result from long-standing loss of blood supply to the ear cartilage and formation of neocartilage from disrupted perichondrium. Management of cauliflower ear involves excision of deformed cartilage and reshaping of the auricle.

Objective To review a single institution's outcomes of free flap reconstruction of the head and neck in patients aged ≥80 years as compared with those <80 years. Study Design Retrospective cohort study. Setting Tertiary academic hospital. Subjects and Methods Patients aged ≥ 80 years who underwent free flap reconstruction of the head and neck between 2007 and 2013 were identified and matched by type of reconstruction with a cohort of younger patients. Outcome measures included flap success, length of stay, discharge disposition, complications, and 2-year mortality. Associations between complications and comorbidities were also evaluated. Results Sixty-six patients aged ≥80 years were identified, and a paired sample <80 years old was selected. There were 3 flap failures per group and 1 perioperative mortality in the elderly group. There was no significant difference in length of stay or major complications between groups. Significantly more elderly patients were discharged to a nursing facility. There was no significant difference in mortality rates at 2 years postoperatively. No associations were seen between level of comorbidity and complications among the elderly group. Conclusion Free flap reconstruction of the head and neck remains a viable option in patients of advanced age. Similar outcomes in terms of flap success, complications, and length of hospitalization can be achieved as compared with younger patients undergoing similar reconstructions. The role of comorbid disease as a predictor of complications remains unclear. There is no significant difference in 2-year mortality for elderly free flap patients versus younger controls.
