A1 Pulley Tenderness as a Modification to Tenderness along the Flexor Sheath in Diagnosing Pyogenic Flexor Tenosynovitis.

Background: Pyogenic flexor tenosynovitis (PFT) is frequently diagnosed by physical examination according to the Kanavel signs. This study proposes a modification of the Kanavel sign "tenderness over the course of the flexor sheath" by including palpation of the A1 pulley to increase specificity for diagnosis. Methods: A retrospective review was performed over 8 months for patients in the emergency department who received a consult to hand surgery to rule out PFT. Two cohorts, nonPFT infections and PFT infections, were studied for the presence or absence of the four Kanavel signs, as well as tenderness specifically over the A1 pulley on the affected digit(s) or T1 pulley of the thumb. Results: There were a total of 33 patients in the two cohorts (21 nonPFT, 12 PFT) with statistically significant differences with regard to the presence of all the Kanavel signs. A1 pulley tenderness had the greatest odds ratio, positive predictive value, specificity, and accuracy when compared with all Kanavel signs. When used in conjunction with each Kanavel sign, there was an increase in specificity in all four signs. Receiver operating characteristic analysis revealed increased area under the curve with A1 pulley tenderness added, indicating improved ability to classify hand infections as PFT versus nonPFT. Conclusion: Although the classic Kanavel signs have shown reliable clinical utility, this study finds that tenderness at the A1 pulley can be a useful specification of "tenderness over the course of the flexor sheath" to help with the diagnosis of PFT.

Automated 3D Analysis of Zygomaticomaxillary Fracture Rotation and Displacement.

BACKGROUND: The zygomaticomaxillary complex (ZMC) can experience a multitude of deforming forces. There is limited understanding on which deformities alter patient outcomes. This study utilized an automated, three-dimensional analysis to elucidate which fracture patterns and rotational deformities are most prevalent and associated with postoperative complications. METHODS: This study was a 7-year retrospective review of patients with unilateral ZMC fractures who underwent surgical intervention. Patient demographics, injury mechanisms, presenting symptoms, and postoperative outcomes were collected. Segmentation was completed using Mimics software. The lateral-medial, superior-inferior, and anterior-posterior axes were manually identified on the zygoma and then displacement, rotational direction, and rotational degrees were automatically calculated using Geomagic software. Total displacement score was generated by summation of individual displacement scores at each of the five sutures. RESULTS: Eighty-one patients satisfied inclusion criteria. The most prevalent rotational pattern of the zygoma was medially-superiorly-posteriorly (P < 0.001). When comparing rotation along the three axes, the zygoma had the greatest rotation along the lateral-medial axis compared with the superior-inferior (P = 0.003) and anterior-posterior (P < 0.001) axes. Within each axis, the zygoma was more likely to rotate medially than laterally (P = 0.003) and posteriorly than anteriorly (P = 0.01). Multivariate analysis identified total displacement scores and degrees rotated along the lateral-medial axis as significant predictors of facial complications and reoperation. CONCLUSIONS: This study suggests that patients with unilateral ZMC fractures who undergo surgical intervention are at an increased risk for adverse outcomes with greater rotation along the lateral-medial axis and higher total displacement scores. Additionally, the automated analysis method described can provide objective data to better characterize ZMC fractures.

Broadening applications and insights into the cross-paramedian forehead flap over a 19-year period.

BACKGROUND: Forehead flap reconstruction of large nasal defects can be challenging. The senior author has used a paramedian forehead flap modification using the supratrochlear artery on the contralateral side of the defect. METHODS: A 9-year retrospective review (2008-2016) was performed for patients undergoing nasal reconstruction with the cross-paramedian forehead flap. Outcomes were analyzed by comparing our previous reviews, which allows us to analyze patient outcomes for over 19 years. RESULTS: Fifty-three patients were identified. The aasal defect was most frequently due to basal cell carcinoma (n = 37, 69.8%). Twenty-three (43%) patients were smokers, and nine (17%) had diabetes. The mean defect size was 12.9 cm2, involving an average of 2.6 nasal subunits. One-third of the patients had cartilage defects (n = 18) and mucosal lining defects (n = 19). Periorbital involvement was present in five patients. Complications included partial flap loss (n = 6), donor site dehiscence (n = 4), flap dehiscence (n = 2), and postoperative infection (n = 1). Only two of the partial flap losses were considered significant, as they required additional reconstructive procedures for soft tissue coverage. Complications were 12 times as likely as those in diabetes (OR = 11.97, p = 0.007, 95% CI 1.94-72.44), six times as likely as those in cartilage defects (OR = 6.4, p = 0.007, 95% CI 1.64-24.92), and nearly five times as likely as those in mucosal lining defects (OR = 4.8, p = 1.27-18.09, 95% CI 1.27-18.09). Thirty-one patients required revisions most commonly for flap debulking (n = 16). CONCLUSION: The cross-paramedian forehead flap is a reliable option in the armamentarium of the reconstructive surgeon for large and complex defects in addition to those with periorbital extension. SUMMARY: Coverage of distal nasal defects after tumor extirpation remains a challenge to the reconstructive surgeon. Our institution uses the cross-paramedian forehead flap for these defects. This flap is based on the supratrochlear artery on the contralateral side of the defect and is oriented obliquely across the forehead for additional length and an improved donor site scar at the level of the eyebrow. The technique and outcomes were published in 2009, and this manuscript serves as an update on outcomes and applications during the past 9 years. By including all our data, we can analyze outcomes for over 19 years. During the past 9 years, 53 patients underwent the cross-paramedian forehead flap technique between 2008 and 2016. These patients were found to have an average defect size of 12.9 cm2 and an average loss of 2.6 nasal subunits. Cartilage defects were present in 34.6% (n = 18) and mucosal defects were present in 36.5% (n = 19) of patients. Five patients had periorbital reconstruction with the forehead flap, of which three patients underwent a single-stage islandized forehead flap reconstruction. Given the large defect size, additional local flaps were frequently used, including nasolabial flaps (n = 16) and cheek rearrangement (n = 11). Complications included partial flap loss (n = 6), donor site dehiscence (n = 4), and postoperative infection (n = 1). Only two of these partial flap losses were considered significant, as they required additional reconstructive procedures to address areas of soft tissue loss. Increased rates of complications were associated with the presence of diabetes and defect characteristics, which reflects increased complexity including mucosal and cartilage loss. When comparing with our prior review of this technique, the more recent population have had increasing complexity of the nasal defects with a large surface area involvement. Overall, the cross-paramedian forehead flap is a reliable option in the armamentarium of the reconstructive surgeon for large and distal nasal defects.

Outcomes Analysis of Chief Cosmetic Clinic Over 13 Years.

BACKGROUND: Adequate resident training in aesthetic surgery has become increasingly important with rising demand. Chief resident aesthetic clinics allow hands on experience with an appropriate amount of autonomy. The purpose of this study was to compare resident cosmetic clinic outcomes to those reported in the literature. Furthermore, we sought to assess how effective these clinics can be in preparing residents in performing common aesthetic surgery procedures. METHOD: A retrospective chart review of 326 patients and 714 aesthetic procedures in our chief cosmetic clinic over a 13-year period was performed, and complication and revision rates were recorded. In addition, an electronic survey was sent to 26 prior chief residents regarding their experience and impressions of the chief resident aesthetic clinic. RESULT: A total of 713 procedures were performed on 326 patients. Patient ages ranged from 5 to 75 years old (mean, 40.8 years old) with a mean follow-up of 76.2 days. On average, there were 56 procedures performed per year. Of the 714 total procedures performed, there were 136 minor procedures and 578 major procedures. Of the 136 minor procedures, there were no complications and there was 1 revision of a cosmetic injection. Of the 578 major procedures, the overall complication rate was 6.1% and the revision rate was 12.8%. Complication and revision rates for each individual surgery were further analyzed and compared with the literature. The complication rates for these procedures fell within the reference ranges reported. In regards to the chief resident survey, there was a 77% response rate. All respondents reported that the chief resident clinic positively affected their residency education and future practice. Ninety percent of respondents felt "very comfortable" performing facelifts, body contouring, and aesthetic breast surgery. No respondents completed a subsequent cosmetic fellowship, and 60% stated that their positive experience in chief clinic contributed to their decision not to pursue a cosmetic fellowship. CONCLUSIONS: Chief resident clinics can provide results with acceptable complication and revision rates that fall within the acceptable ranges in the literature. In addition, it provides a valuable experience that leaves residents with high comfort levels in performing key procedures in aesthetic surgery.

The patient's perioperative perspective during the treatment of obstructive sleep apnea: a pilot study.

PURPOSE: This study aims to determine patients' pre-operative and post-operative experiences relating to surgical treatment for obstructive sleep apnea (OSA), while understanding how patients' perceptions influence their outcome and satisfaction. METHODS: This is a phenomenological qualitative study using a semi-structured interview to evaluate patients who failed continuous positive airway pressure (CPAP) treatment of obstructive sleep apnea and underwent airway surgery. Meaningful codes from the interviews were organized into overarching themes of patient experiences. The same surgeon in a tertiary care otolaryngology practice treated all patients. All patients underwent a modified or traditional uvulopalatopharyngoplasty (UPPP) between 2009 and 2013. Patients were diagnosed with OSA by polysomnogram and had failed CPAP use. Patients were interviewed regarding their experience with OSA, CPAP, and surgery. Thematic saturation was reached after 17 patients. RESULTS: Six themes exemplify patient's experience of OSA and treatment: (1) OSA impacted patients personally and professionally, (2) CPAP discomfort limited its therapeutic use, (3) patients had personal motivations for undergoing surgery, (4) patient knowledge influenced their perceptions, (5) post-operative challenges exceeded patient expectations, and (6) post-operative outcomes reflected positive effect on patients. CONCLUSIONS: Patients' experiences prior to surgery can largely influence their perceived outcome and satisfaction. Post-operative sleep studies may not capture the full outcome of the patients' response to surgery. This study suggests that the patient's subjective reported outcomes should be used in conjunction with objective post-operative sleep studies.

Anaplastic Large Cell Lymphoma: Emerging Consent and Management Patterns among American and International Board Certified Plastic Surgeons.

BACKGROUND: Although literature and case reports regarding anaplastic large cell lymphoma (ALCL) continue to increase, changes in plastic surgery practice patterns have not been assessed. METHODS: A 19-question survey was sent electronically to U.S. and international board-certified plastic surgeons. Data were analyzed using chi-square test and logistic regression analysis. RESULTS: A total of 1383 surgeons (U.S., 715; international, 668) responded, at a rate of 13.5 percent, and 36.2 percent of U.S. physicians aspirate late seromas and send for cytologic analysis and 9.5 percent had personal experience with ALCL, equating to at least 193 self-reported cases. Overall, 26.9 percent discuss ALCL risk at the initial consultation every time, and 36.4 percent include ALCL in the informed consent. Compared to U.S. counterparts, Australian, French, and German physicians were five times as likely to include ALCL in consent. Physicians in an academic practice and those frequently (>40 percent) using textured implants were more likely to discuss ALCL in the preoperative consultation. Physicians with personal or colleague experience with ALCL were twice as likely to include ALCL in the consent process. CONCLUSIONS: Only one-third of surgeons are managing late seroma according to U.S. Food and Drug Administration guidelines. ALCL cases are likely being underreported. Collectively, plastic surgeons remain hesitant to change consent pattern. However, specific countries have adapted their consenting processes. Working in academia and frequent textured implant use makes one more likely to discuss ALCL in consultation. Personal or colleague experience makes one twice as likely to include ALCL in the consent.
