Rotation and transposition flaps in facial plastic and reconstructive surgery

Reconstructive defects of the human face pose unique challenges to even the most experienced surgeon given their myriad of presentations and the individuality of each patient’s anatomy, clinical presentation, and perspective or preferences. A robust armamentarium of reconstructive options must be cultivated for each facial subunit so that experience and artistry can be best utilized to rebuild the patient’s structure and function. This review will outline a subset of local rotation and transposition flaps that are most useful for facial reconstruction, organized by facial subunit.

Premenarche bilateral giant juvenile fibroadenoma of breast: literature review with a case report

Fibroadenoma is a common abnormality which every surgeon has been exposed to, and there are several international guidelines regarding its management. However giant fibroadenomas, especially in the premenarche setting has been a rare occurrence, even for the experienced surgeon. Various reports have shown that we need to treat this condition more aggressively than the normal fibroadenoma, and issues of cosmesis in a developing breast along with the aim to preserve lactation functionality becomes an issue. Since these cases remain a single life time experience for most surgeons, there is a sparsity of treatment protocols even in literature. Through this paper we hope to shed some valuable insight to this rare disorder and help surgeon colleagues, when dealing with similar cases.

Radiographic Outliers, Revisions, and Functional Outcomes in Fixed-Bearing Medial Unicompartmental Arthroplasty

Background and Hypothesis: Unicompartmental Knee Arthroplasty (UKA) is a technically demanding procedure vulnerable to errors in component positioning. Recent studies suggest robotic-assistance improves precision of implant placement, minimizes outliers, and improves survivorship. However, we have previously demonstrated an experienced surgeon can match robotic accuracy. This study evaluated revision rates and functional outcomes of radiographic outliers in manual UKA. Experimental Design or Project Methods: A retrospective review of 222 consecutive fixed-bearing medial UKAs was conducted. Implant positioning and alignment were assessed radiographically measuring tibial coronal (TCA), femoral coronal (FCA), tibial sagittal (TSA) and femoral sagittal (FSA) angles as well as implant overhang. UCLA Activity Level and all-cause survivorship were evaluated. Student’s t-test, Chi square, and Kaplan Meier curves were used in analyses with alpha ≤ .05 designating statistical significance. Results: Using previously published alignment goals, our manual UKAs achieved the following targets: 92% for TCA, 100% for FCA, 88% for TSA, and 100% for FSA. For implant overhang, 100% met medial, anterior, and posterior targets. Our manual UKAs achieved desired alignment and overhang goals more frequently than previously published manual success. Survivorship free from aseptic revision in this study was 96% at 8.5 years. Additionally, there was no difference in UCLA Activity Level improvement comparing outliers and non-outliers (p³0.159). Conclusion and Potential Impact: Manual UKAs performed by an experienced surgeon showed improved success in achieving alignment and implant overhang goals compared to published manual UKA data and similar success compared to published robotic-assisted UKA data. We found no differences in revision rates or functional outcomes between outliers and non-outliers using previously published targets. For robotic assistance to be cost effective, it must demonstrate improved outcomes or survivorship when compared to manual UKAs. Our results contradict recently published claims that manual alignment outliers and failure rates fail to meet expectations for UKA.

Laparoscopic Cholecystectomy after Endoscopic Retrograde Cholangiopancreatography

Background Laparoscopic cholecystectomy (LC) post Endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy(ES) is generally accepted as the treatment of choice for patient with choledococystolithiasis. Previous studies have shown that LC after ERCP is associated with a high conversion rate. The aim of the present study was to assess the complexity of LC after ERCP compared with standard LC for symptomatic uncomplicated cholecystolithiasis. Objective s: So the aim of this study is to assess the complexity of LC post ERCP comparted to elective LC without previous ERCP. Method The study is a prospective cohort study of two groups of patients: patients who had undergone a previous ERCP for choledocolithiasis (PES) and patients with cholecystolithiasis who had no previous intervention prior to LC (NPES). Results The PES group consists of 25 patients and the NPES group consists of 25 consecutive patients, patients in the PES group had a higher risks for longer (more than 35 min) duration of operation, the conversion rate in the PES group and the NPES group (12% versus 0%, respectively) were not significantly different, duration of post-operative hospital stay in the PES group was longer than NPES group, there was more difficulty in achieving the critical view of safety in the PES group (easily achieved in 48%) than NPES group(easily achieved in 92%). Conclusion A laparoscopic cholecystectomy after ES is longer and more difficult than in uncomplicated cholelithiasis and should therefore be performed by an experienced surgeon.

Performing Microdissection Testicular Sperm Extraction: Surgical Pearls from a High-Volume Infertility Center

Microdissection testicular sperm extraction (mTESE) has been demonstrated to be the gold-standard surgical technique for retrieving testicular sperm in patients with non-obstructive azoospermia (NOA) as it enables the exploration of the whole testicular parenchyma at a high magnification, allowing the identification of the rare dilated seminipherous tubules that may contain sperm, usually surrounded by thinner or atrophic tubules. MTESE requires a skilled and experienced surgeon whose learning curve may greatly affect the sperm retrieval rate, as demonstrated in previous reports. The present review is intended to offer a precise and detailed description of the mTESE surgical procedure, accompanied by an extensive iconography, to provide urologists with valuable information to be translated into clinical practice. Advice about the pre-surgical and post-surgical management of patients is also offered.

Contour Map Point Distribution and Surgeon Experience Level Affect Accuracy of Surgical Navigation in a Pilot Study

Background: Reliable use of surgical navigation depends upon the registration process. The gold standard is paired-point registration with bone-anchored fiducials, but contour-map registration is more practical. Surgeons may employ variable contour maps and less experienced team members often perform this critical step. The impact of these practices on target registration error (TRE) is not well-studied. Methods: A dry lab set-up consisting of a navigation system (Fusion ENT, Medtronic, Jacksonville, FL) and a sinus phantom with 2 mm radiopaque spheres in the sphenoid and ethmoid regions was developed. A CT (0.625 mm slice thickness) was obtained. Registration was performed with a contour-based protocol. Accuracy was determined using the software’s distance measurement tool. Registration was performed with narrow-field (NF; forehead points medial to the mid-pupillary line) and wide field (WF; entire forehead) contour maps. An experienced rhinologist and a resident surgeon performed each registration in triplicate and TRE at the sphenoid and ethmoid markers was measured in triplicate. Results: WF mapping had a lower TRE than NF (1.09 mm [95% Confidence Interval (CI) 0.96-1.22] vs 1.68 mm [95% CI 1.50-1.86]). The experienced surgeon had a lower TRE compared to the resident (1.21 mm [95% CI 1.08-1.34] vs 1.54 mm [95% CI 1.35-1.74]). Conclusions: In this navigation model, wide field mapping offers better accuracy than narrow-field mapping, and an experienced surgeon seemed to achieve better accuracy than a resident surgeon. These observations have potential implications for the use of this technology in the operating room.

Surgery for Bowen Disease: Clinicopathological Factors Associated With Incomplete Excision

Background: One common treatment for Bowen’s disease (BD) is surgical excision, but there is no international consensus on the appropriate surgical margins. Objectives: This study examined what factors affect the rate of incomplete excision of BD. Methods: Clinicopathological data potentially linked to surgical outcome (complete or incomplete excision) were retrospectively collected from medical and histopathological records on all surgically excised BD lesions diagnosed at Sahlgrenska University Hospital in Gothenburg, Sweden during 2014-2015. Data were analyzed with two definitions of incomplete excision: less strict (ie, BD present at the surgical margin) and strict (ie, dysplasia present at the surgical margin). Results: In total, 463 BD lesions among 408 patients were included. With the less strict definition, 3 factors were associated with significantly higher rates of incomplete excision: surgical margins <3 mm, a less experienced surgeon, and use of punch biopsy excision. The same factors plus a tumor location on the head and neck area or upper extremities were associated with significantly higher rates of incomplete excision using the strict definition. After adjustment for confounders, less experience was independently associated with incomplete excision using the less strict definition, whereas less experience and location on the head and neck area or upper extremities were independently associated with incomplete excision using the strict definition. Surgeon specialty was not associated with incomplete excision regardless of the definition. Conclusions: When removing BD surgically, an elliptical excision with surgical margins ≥3 mm carried out by an experienced surgeon should be recommended. Surgical margins may need to be adjusted depending on body site.

Surgery to relieve nasal obstruction: outcome for 366 patients operated on by one senior surgeon

Background Studies of patient-rated outcome in septoplasty and turbinoplasty most frequently involve several surgeons with varying surgical skills, techniques and experience. The aim of the present study was to evaluate outcome based on one experienced surgeon. Methods Three hundred and sixty-six consecutive patients referred for nasal obstruction were included. All the patients were examined with nasal endoscopy before and after decongestion, they filled out a nose VAS and rated their overall general health before and three to six months after surgery. The patients underwent septoplasty, septoplasty plus turbinoplasty or turbinoplasty. Results The mean nose VAS for nasal obstruction (0–100) preoperatively was 64.7 for all patients. Patients undergoing septoplasty (n = 159) were younger than patients undergoing septoplasty + turbinoplasty (n = 79) or patients undergoing turbinoplasty alone (n = 128). The nose VAS for nasal obstruction improved significantly in all three groups and 25% had a normal nose VAS after surgery in the septoplasty and septoplasty + turbinoplasty groups compared to only 8% in the turbinoplasty alone group. There was no significant difference in the improvement in nasal obstruction between septoplasty and septoplasty + turbinoplasty, but the septoplasty + turbinoplasty group experienced a significantly greater improvement in general health. Conclusions In 366 patients operated on by one experienced surgeon, septoplasty and septoplasty + turbinoplasty were more effective at relieving nasal obstruction than turbinoplasty alone. Septoplasty + turbinoplasty resulted in a greater improvement in general health than septoplasty alone, despite the same improvement in nasal obstruction, indicating a beneficial effect of additional turbinoplasty in septoplasty.
