No full textSurgical Reconstruction following Wide Local Excision of Malignant Melanoma of the Scalp
No full textBackground: Scalp reconstruction in cases of melanoma excision can be challenging due to specific functional and aesthetic outcome requirements. Reconstructive techniques reported in the literature were reviewed to establish whether a surgical algorithm for the management of melanoma of the scalp may be deduced. Methods: A literature search was conducted to evaluate reconstructive strategies after melanoma wide local excision of the scalp according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Inclusion criteria were English language, diagnosis of melanoma of the scalp, and the presence of the following data: characteristics of the residual defect (width and depth), type of reconstruction, follow-up, and surgical outcome. Results: Six hundred twenty-five records were identified after excluding the duplicates; 48 full-text articles were assessed for eligibility, and 17 records were selected for inclusion. A total of 39 patients were included in the review. The majority of patients (n = 20) underwent skin grafting subsequent to dermal regeneration template positioning. Local flaps (n = 10), free flaps (n = 7), skin grafting alone (n = 1), and dermal regeneration template positioning alone (n = 1) were less frequent. Conclusions: Numerous reconstructive strategies for the scalp are described in the literature. Melanoma patients present a greater variability in terms of general health conditions and social needs that must be taken into account while choosing the most suitable procedure
Decompression Surgery for Frontal Migraine Headache
No full textIntroduction: Migraine headache (MH) is one of the most common diseases worldwide and pharmaceutical treatment is considered the gold standard. Nevertheless, one-third of patients suffering from migraine headaches are unresponsive to medical management and meet the criteria for "refractory migraines" classification. Surgical treatment of MH might represent a supplementary alternative for this category of patients when pharmaceutical treatment does not allow for satisfactory results. The goal of this article is to provide a comprehensive review of the literature regarding surgical treatment for site I migraine management. Methods: A literature search using PubMed, Medline, Cochrane and Google Scholar database according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines was conducted using the following MeSH terms: "frontal neuralgia," "frontal trigger site treatment," "frontal migraine surgery" and "frontal headache surgery" (period: 2000 -2020; last search on 12 March 2020). Results: Eighteen studies published between 2000 and 2019, with a total of 628 patients, were considered eligible. Between 68% and 93% of patients obtained satisfactory postoperative results. Complete migraine elimination rate ranged from 28.3% to 59%, and significant improvement (>50% reduction) rates varied from 26.5% to 60%. Conclusions: Our systematic review of the literature suggests that frontal trigger site nerve decompression could possibly be an effective strategy to treat migraine refractory patients, providing significant improvement of symptoms in a considerable percentage of patients

No full textThoracodorsal Artery Perforator Flap in Partial Breast Reconstruction: A Systematic Review
No full textIntroduction: Breast conserving surgery followed by radiation therapy represents the standard of care for early stage breast cancer. Oncoplastic breast surgery includes several reconstructive techniques essentially summarized in 2 categories: volume displacement and volume replacement procedures. These latest procedures have evolved over time from the use of the entire latissimus dorsi muscle to the use of pedicled perforator flaps, namely the thoracodorsal artery perforator (TDAP) flap. The aim of this article is to provide a comprehensive review of the literature regarding the use of the TDAP flap in partial breast defects. Methods: A literature search was performed via PubMed, Medline, and Cochrane. Studies reporting the use of the TDAP flap after breast conserving surgery were included. Patient characteristics, topography and size of breast defect, flap size and design, number of perforators, and operative time were analyzed. Moreover, aesthetic and functional (shoulder morbidity) results, patient satisfaction, postoperative complications, and donor site morbidity were registered. Results: Twelve articles fulfilled inclusion criteria, and 337 patients were included. All articles except 1 described the use of the TDAP flap for defects in every breast quadrant. The mean weight of resected breast tissue was 97.28 g, and patients with over 20% of volume deficiency were considered eligible for TDAP flap volume replacement. The ellipse-shaped skin paddle (oriented oblique downward, transversal or oblique upward in most cases) was extended over the anterior border of the latissimus dorsi muscle to include possible septocutaneous perforator vessels. Most authors began the dissection from the anterior and caudal border of the flap to reserve the possibility to convert the TDAP to a musculocutaneous flap and check for septocutaneous perforators. Flap size ranged from 4 × 12 to 21 × 9 cm. The mean procedure time was 192.21 minutes. Mean follow-up was 17.42 months. Evaluation by way of a 5-point Likert scale reported overall mean values of over 4 points. Satisfactory outcomes were reported in 92.85%-100% of cases. Patient satisfaction ranged from 80% to 94% of cases. The incidence of seroma (1 case) and "shoulder-related" donor site morbidity was very low. Conclusions: Despite the heterogeneity of the evaluation methods, our review suggested that the use of the TDAP flap in oncoplastic surgery allows for satisfactory aesthetic outcomes and quite high levels of patient satisfaction. The TDAP flap represents an effective and versatile tool that amplifies the oncoplastic surgeon's arsenal, which allows for satisfactory outcomes
Breast Reconstruction Using the Lateral Thoracic, Thoracodorsal, and Intercostal Arteries Perforator Flaps
No full textBackground: Breast-conserving surgery followed by radiotherapy represents the standard of care for early-stage breast cancer. The aim of this article was to provide a review of the literature about the use of the lateral thoracic artery perforator (LTAP) flap, the lateral thoracodorsal (LTD) flap, and the lateral intercostal artery perforator (LICAP) flap in lateral partial breast defect. Methods: A literature search was performed via PubMed, Medline, and Cochrane. Patient's characteristics, topography and size of breast defect, flap size and design, number of perforators, and operative time were analyzed. Aesthetic and patient-reported outcomes, postoperative complications, and donor site morbidity were also registered. Results: Thirteen articles fulfilled inclusion criteria, and 432 patients were included. Different flap designs and flap combinations were described. Satisfactory outcomes were reported for between 78% and 100% of cases. Patient satisfaction ranged from 75.8% to 92.5% of cases. The overall complication rate was 9.25%, and donor site morbidity was very low (3.7%). Conclusions: A distinct advantage of LTAP, LTD, and LICAP flap reconstruction is that the thoracodorsal pedicle is not sacrificed, not compromising eventual delayed breast reconstruction with TDAP or latissimus dorsi flaps. This staged approach to partial breast reconstruction is especially useful in cases where the oncological margins are uncertain and wider resections (or mastectomies) are secondly required
Prepectoral implant pocket conversion in breast reconstruction
No full textIntroduction: While many authors have reported their experience in immediate prepectoral breast reconstruction (BR), implant pocket conversion from a submuscular to a prepectoral plane is less well described. The aim of this study is to provide a comprehensive review on plane conversion in implant-based BR, including the indications, surgical techniques, functional, and esthetic results. Materials and Methods: A literature search via PubMed, Medline, Google Scholar, and Cochrane databases was performed using the following MeSH terms: “prepectoral pocket conversion”, “subcutaneous pocket conversion”, “prepectoral plane conversion”, “subcutaneous plane conversion”, and “prepectoral breast reconstruction”. Results: Ten articles in which 504 breasts were studied were deemed eligible for inclusion. The indications to perform plane conversion were animation deformity (AD), chronic pain, and implant malposition. Seven studies described complete or partial capsulectomy. The use of acellular dermal matrices (ADM) was reported in all cases except for three studies. The mean follow-up was 10.64 months. There was resolution of AD in 100% of cases. Three studies reported complete resolution of chronic pain. The overall complication rate was 12.102% and capsular contracture (CC) was the most frequent complication. Cosmetic revisions were reported in six studies (9.52%). The use of ADMs and fat grafting appeared to decrease the rate of subsequent CC formation and cosmetic revisions. Conclusions: The current article represents the first review about implant pocket conversion from a submuscular to a prepectoral plane, delineating its indications, surgical technique, postoperative complications, and functional and esthetic outcomes
Peripheral Occipital Nerve Decompression Surgery in Migraine Headache
No full textBackground: Migraine headache in the occipital region is characterized by a recurrent pain of moderate to severe intensity. However, the diagnosis can be difficult because of the multitude of symptoms overlapping with similar disorders and a pathophysiology that is not well-understood. For this reason, the medical management is often complex and ineffective. Methods: A literature search according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines was conducted to evaluate the surgical treatment of occipital migraines. Inclusion criteria were: English language, diagnosis of migraine, occipital neuralgia, or tension headache in compliance with the classification of the International Headache Society, follow-up at minimum 3 months, and adult age. The treatment had to consist of peripheral occipital nerve surgery. Results: 323 records were identified after duplicates were removed, 30 full text articles were assessed for eligibility, and 9 records were selected for inclusion. A total of 1046 patients were included in the review. General positive response after surgery (>50% reduction in occipital migraine headaches) ranged from 80.0% to 94.9%. However, many differences in the selection of patients, target of decompression surgery, and measurement outcome were described. Conclusion: Despite the decennial proven effectiveness and safeness of surgical therapy for chronic occipital migraine headaches, more significant proof is needed to definitively confirm its use as a standard therapy
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
