The Effect of Leg Dominance in Patients on Perforator-Based Flaps Elevated From the Lower Extremities.

BACKGROUND: The lower extremities are the largest donor sites in the body for perforator flap reconstruction. Multislice row computed tomography angiography allows for a multiplanar assessment of perforators using a large number of three-dimensional images with high resolution. In this study, the effect of leg dominance on perforator flap donor site preference was investigated radiologically to increase preoperative perforator mapping precision and surgical success. PATIENTS AND METHODS: The study included 40 patients. Superior gluteal artery perforator (SGAP) flap, inferior gluteal artery perforator (IGAP) flap, superficial circumflex iliac artery perforator flap, anterolateral thigh (ALT) flap, profunda artery perforator (PAP) flap, medial sural artery perforator (MSAP) flap, peroneal artery perforator (PP) flap, and posterior tibial artery perforator (PTAP) flap were analyzed according to their number of perforators (> 0.8-mm perforators counted, number of larger perforators [nLP]), dominant perforator diameter (DPD), related muscle thickness (RMT), and related subcutaneous tissue thickness (RSTT) in each leg. RESULTS: Of these 40 patients, 35 (87.5%) were right-leg dominant and 5 (12.5%) were left-leg dominant. The dominant leg had higher DPD for MSAP, PTAP, and PP than the nondominant leg (p = 0.08, p = 0.06, and p = 0.06, respectively). The dominant leg had a significantly higher nLP (> 0.8 mm) in MSAP, PTAP, and PP flaps than the nondominant leg (p < 0.05). Except for the PAP flap (adductor magnus muscle; p > 0.05), RMT of all other perforator flaps (SGAP, IGAP, ALT, MSAP, PTAP, and PP) was statistically higher in the dominant leg (p < 0.05). There was no statistically significant difference in RSTT between any of the two groups (p > 0.05). CONCLUSION: According to findings, the dominant leg could be considered a donor site preference to improve surgical outcomes and reduce microsurgical complications due to an increased nLP, perforator diameter, and RMT.

"The Jigsaw Puzzle Locking Technique" to Augment the Stabilization between the Septal Cartilage and Extension Graft in End-to-End Suture Fixation.

INTRODUCTION: Nasal tip stability is crucial for long-lasting results. Usage of the extension graft is one of the most reliable stabilization techniques. With a septum in the midline, the extension graft is fixed end to end. The "jig-saw puzzle technique" reinforces this end-to-end fixation. The specific protrusion on one piece of the puzzle is inserted in a groove on adjacent piece. This settlement provides stabilization between the pieces. Application of this philosophy between the nasal septum and extension graft may provide a long-term fixation. MATERIAL METHOD: Between April 2022 and March 2024, the "jig-saw puzzle technique" was applied in 26 female patients. Trapezoid-shaped protrusion was created at the septum. Similar indentation was created at the extension grafts. The protrusion is then settled in the indentation. The preop, immediate postoperative and one-year postoperative pictures are compared to assess the rotations and projections with Adobe Photoshop Program. RESULTS: All 26 patients were females with mean age 27.5 years (20-32). Satisfactory graft stabilization was obtained without loss of projection and rotation in all patients. Statistically significant difference was found between the preoperative, immediate postoperative and postoperative 1-year projection and rotation assessments of the patients (p = 0.001; p < 0.01). The results were evaluated at a 95% confidence interval and significance was evaluated at p < 0.05 level. These statistical analyses verify that both projection and rotation were preserved with jig-saw puzzle technique. CONCLUSION: The jigsaw puzzle technique may provide suture-independent, long-term end-to-end fixation opportunity of the septal cartilage and the extension graft.

The Effects of the Maxillary Movements in Angle Class 2 and 3 Malocclusion Treatment on Nose Air Flow Amount, Rate, and Resistance.

Maxillary movements performed during orthognathic surgery affect the external and internal anatomy of the nose. The functional and anatomical effects may change nasal airway parameters after the surgery, and these alterations can be examined objectively by rhinomanometry. In this study, patients who underwent maxillary orthognathic surgery were divided into 3 groups based on their surgical plans: advancement (group 1), impaction and advancement (group 2), and setdown and advancement (group 3). Preoperative and postoperative rhinomanometric data including the average nasal volume, minimum cross-sectional area, average airflow resistance of the right and left nasal passageways, and an average of both nasal passages were collected. The study included 50 patients who underwent orthognathic surgery between October 2021 and October 2022. There were 20 patients each in group 1 and group 2 and 10 patients in group 3. The average nasal passage volume increased in the advancement (group 1) and impaction-advancement (group 2) groups. In addition, the advancement (group 1) group had a decreased average airflow resistance. Setdown-advancement (group 3) group did not show a positive or negative effect on nasal airway parameters. Maxillary movements during orthognathic surgery revealed no adverse effect on nasal parameters. Moreover, advancement and impaction positively affected nasal functional and anatomical parameters.

Investigation of the Relationship of Functional Improvement and Body Mass Index in Breast Reduction Patients.

INTRODUCTION: Due to macromastia, center of gravity changes and neck, shoulder, back pain become prominent. Macromastia and obesity separately cause pain and an increase in curves of vertebra. The aim of this study is to compare the functional benefits of reduction mammoplasty between obese and non-obese patients. MATERIALS AND METHODS: Data of this retrospective study were collected from archives and include preoperative/postoperative thoracic Cobb angles, preoperative/postoperative VAS scores, BMI and resected breast tissue weight of patients who underwent reduction mammaplasty operations between August 2017 and April 2019 in Plastic, Reconstructive and Aesthetic Surgery Department. RESULTS: This study shows that reduction mammoplasty enables significant decrease both in thoracic kyphosis angles and in neck, shoulder and back VAS scores. However, no significant difference was found in preoperative/postoperative values and mean amount of changes of thoracic kyphosis angles between obese and non-obese patients. Decreases in neck, shoulder and back VAS scores were not found statistically significant between two groups. The breast resection amount was not related to correction of kyphosis, but it enabled only a significant decrease in neck VAS scores. CONCLUSION: Functional improvement was not related to body mass index in reduction mammoplasty patients. Functional benefits were observed similarly in both obese and non-obese patients. A precise threshold value for body weight, body mass index and amount of breast tissue could not be defined as an indication for functional reduction mammoplasty.

A Novel Surgical Technique for Gynecomastia: Air-Assisted Minimally Invasive Surgery With Single Axillary Incision.

BACKGROUND: Gynecomastia is a benign condition that develops due to the proliferation of breast tissue in men. Surgical excision is the most effective treatment method. Minimally invasive techniques can be used to avoid visible scarring. We evaluated the efficacy and safety of air-assisted subcutaneous mastectomy in the treatment of gynecomastia. PATIENT AND METHODS: 10 patients with gynecomastia underwent air-assisted subcutaneous mastectomy and liposuction through a single axillary incision, between June 2022 and February 2023. Demographic and clinical data of the patients, duration of surgery, and complications were recorded. The satisfaction levels of the patients regarding physical appearance, mental status, and social environment were measured. The body Q questionnaire was performed preoperatively and in the postoperative third month. RESULTS: The median age was 26 (range, 18-54). Surgical excision was measured as a median of 69 gr (range, 41-177), and liposuction volume was measured as a median of 210 ccs (range, 63-400). The median operation time was 50 minutes (range, 21-60) for excision and 21 minutes (range, 20-75) for liposuction. Body, chest, and nipples related appearance satisfaction levels were measured preoperatively as a median of 44 (range, 36.5-52), 31 (range, 27.5-39), and 51.5 (range, 21-69.8) points vs postoperatively as 92 (range, 92-100), 93 (range, 93-94.8) and 90 (range, 90-100) points, respectively. The patients had a median follow-up of 6 months (range, 3-11). No complications were observed during the follow-up period. CONCLUSION: Air-assisted subcutaneous mastectomy and liposuction is a feasible technique that may provide good cosmetic outcomes by avoiding anterior chest wall scarring.

Single and double injection paravertebral block comparison in reduction mammaplasty cases: a randomized controlled study.

BACKGROUND: This study compares the analgesic effects and dermatomal blockade distributions of single and double injection bilateral thoracic paravertebral block (TPVB) techniques in patients undergoing reduction mammaplasty. METHODS: After obtaining ethics committee approval, 60 patients scheduled for bilateral reduction mammaplasty were included in the study. Preoperatively, the patients received one of single (Group S: T3-T4) or double (Group D: T2-T3 & T4-T5) injection bilateral TPVBs using bupivacaine 0.375% 20 ml per side. All patients were operated under general anesthesia. The T3-T6 dermatomal blockade distributions on the midclavicular line were followed by pin-prick test for 30 min preoperatively and 48 h postoperatively. All patients received paracetamol 1 g when numeric rating scale (NRS) pain score was ≥ 4, and also tramadol 1 mg/kg when NRS was ≥ 4 again after 1 h. The primary endpoint was NRS pain scores at postoperative 12th h. The secondary endpoints were dermatomal blockade distributions and NRS scores through the postoperative first 48 h, time until first pain and the analgesic consumption on days 1 and 2. RESULTS: Fifty-two patients completed the study. The NRS pain scores at 12th h were similar (right side: P = 0.100, left side: P = 0.096). The remaining NRS scores and other parameters were also comparable within the groups (P ≥ 0.05). Only single injection TPVB application time was shorter (P < 0.001). CONCLUSIONS: The single injection TPVB technique provided sufficient dermatomal distribution and analgesic efficacy with the advantages of being faster and less invasive.

Integrating artificial intelligence in orthognathic surgery: A case study of ChatGPT's role in enhancing physician-patient consultations for dentofacial deformities.

Orthognathic surgery, a multidisciplinary treatment for dentofacial deformities, presents complex preoperative preparations and follow-up procedures. This study aims to evaluate the effectiveness of ChatGPT-4, an artificial intelligence-based language model, as a supportive tool during patient consultations for orthognathic surgery. Nine critical questions that candidates for orthognathic surgery should ask during a consultation were identified and posed to ChatGPT-4. The responses were subsequently assessed by experienced plastic surgeons and collaborating orthodontists at a leading orthognathic surgery center. Evaluations focused on the accuracy, clarity, and comprehensibility of the information provided. ChatGPT-4 generated comprehensive, clear, and accurate responses, offering critical technical information to guide patients through the complexities of orthognathic surgery. However, it consistently underscored the necessity of individualized responses and emphasized that specialized medical consultation is crucial for treatment and follow-up plans. While ChatGPT-4 shows promise as a reliable informational resource, it cannot fully replace the nuanced physician-patient relationship, particularly in situations requiring emotional intelligence and specialized expertise. ChatGPT-4 can serve as an informative and guiding assistant during the consultation process for orthognathic surgery, although it cannot substitute for direct medical consultation. This tool could be an asset for both patients and physicians in managing the intricate treatment process of orthognathic surgery.

Reduction of the scar burden at the donor area of the radial forearm flap with the aid of an endoscopic pedicle preparation.

BACKGROUND: The radial forearm flap is one of the most commonly used flaps of reconstructive microsurgery with its long pedicle and thin structure. The donor site at the forearm is a visible anatomic region that has high mobility and functional importance. In this study, a longitudinal and large scar was avoided on the forearm during pedicle dissection of the conventional radial forearm flap with the utilization of an endoscope. Furthermore, arterial, venous, and nervous injuries were avoided by performing a separate inci-sion of 2-3 cm at the cubital fossa to reduce flap failure and donor site morbidity. METHODS: The patients who underwent pedicle dissection of the radial forearm flap with the aid of an endoscope for head-neck reconstruction between 2014 and 2021 were included in this study. The flap was harvested from the subfascial plane. The cephalic vein was used in all of the patients. When the pedicle dissection reached the antecubital region, an incision of 2-3 cm was performed from the skin. Two vein anastomoses were performed for each patient. RESULTS: This retrospective study consists of 51 patients. While 45 of the patients were the result of head and neck cancer, six of them had a defect caused by trauma. The average area of skin islands was 40.3 cm2, while the full-thickness skin graft size was 24.2 cm2. An average of 2.6 cm of scar tissue was formed at the antecubital region. No venous or arterial compromise was observed in the post-operative period. There was no partial or total flap loss in any patient. Localized numbness persisted in the skin area where the superficial sensory branch of the radial nerve is located in 6 (11.7%) patients. CONCLUSION: With endoscopic radial forearm flap harvesting, the longitudinal incision in the forearm and wound healing prob-lems are avoided. The absence of partial or total flap loss has shown that endoscopic harvesting of the radial forearm flap is a safe and reliable method.

Evaluation of Shoulder Muscle Improvement in Patients Following Free Latissimus Dorsi Muscle Pedicle Flap Transfer.

Aim: This study aimed to evaluate the clinical outcomes, shoulder muscle strength, and donor site morbidity following the free latissimus dorsi (LD) muscle pedicle flap transfer. Materials: Patients with free LD muscle pedicle flap reconstructions and with asymptomatic shoulders (affected and contralateral side) were included. The follow-up duration was 12 months. The combined shoulder range of motion (ROM), Constant-Murley shoulder (CMS), and quick disabilities of the arm, shoulder, and hand (QuickDASH) scores were measured preoperatively and at 1 year postoperatively. The ratio of the isokinetic muscle strength and total work was measured with an isokinetic dynamometer (Cybex 350®) both preoperatively and at sixth month postoperatively. Results: Twenty patients with a mean age of 37.06 ± 9.74 years and a mean body mass index of 23.49 ± 8.6 kg/m2 were included. The difference in shoulder ROM and CMS and increase in QuickDASH were not significant at the first postoperative year. The peak torque and total work performed decreased by 13%-16% for the adductor and extensor functions at the six month postoperatively, and these differences were significant. Although the adductor peak torque was significantly lower in the postoperative test of the operated side, no significant difference was found between the operated and unaffected shoulder peak torque values. Moreover, no significant difference was noted between the operated and unaffected shoulders in all isokinetic tests pre- and postoperatively. Conclusion: The free LD muscle pedicle flap harvest did not decrease function and ROM at the first postoperative year. The muscle strength and total work of shoulders after the LD muscle transfer returned to the preoperative condition at the sixth month, except adductor and extensor muscle strengths. However, adductor and extensor muscle strengths of the operated shoulders were not significantly different postoperatively.

Objectif: La présente étude visait à évaluer les résultats cliniques, la force musculaire de l'épaule et la morbidité au site donneur après un transfert du lambeau pédiculaire libre du grand dorsal. Matériaux: Des patients ayant subi une reconstruction du lambeau pédiculaire libre du grand dorsal et dont les épaules étaient asymptomatiques (côté touché et côté controlatéral) ont participé à l'étude. Le suivi a duré 12 mois. Les chercheurs ont évalué l'amplitude de mouvement (AM) combinée de l'épaule, le score de Constant-Murley (SCM) et le score rapide des incapacités du bras, de l'épaule et de la main (QuickDASH) avant l'opération, puis un an plus tard. Ils ont mesuré le ratio entre la force musculaire isocinétique et le travail total au moyen d'un dynamomètre isocinétique (Cybex 350®) avant l'opération, puis six mois plus tard. Résultats: Au total, 20 patients d'un âge moyen de 37,06 ± 9,74 ans et à l'indice de masse corporelle moyen de 23,49 ± 8,6 kg/m2 ont été inclus dans l'étude. La différence de l'AM et du SCM de l'épaule et l'augmentation du QuickDASH étaient légères pendant l'année suivant l'opération. Le couple de pointe et le travail total effectués avaient diminué de 13 % à 16 % pour la fonction des adducteurs et des extenseurs six mois après l'opération, ce qu'on peut qualifier de différences importantes. Même si le couple de pointe des adducteurs était beaucoup plus faible au test postopératoire du côté opéré, aucune différence importante n'a été observée entre les valeurs du couple de pointe de l'épaule opérée et de celle non touchée. De plus, lors de tous les tests isocinétiques exécutés avant et après l'opération, ils n'ont pas remarqué de différence importante entre l'épaule opérée et l'épaule non atteinte. Conclusion: Le lambeau musculaire pédiculaire libre du grand dorsal ne diminuait pas la fonction et l'AM pendant l'année suivant l'opération. La force musculaire et le travail total des épaules après le transfert du grand dorsal avaient retrouvé leur état préopératoire au sixième mois, sauf la force des muscules adducteurs et extenseurs. Cependant, la force des muscles adducteurs et extenseurs des épaules opérées n'avait pas tellement changé après l'opération.

The Comprehensive Evaluation of the Pinch Deformity due to Concave Alar Cartilages and Its Management.

INTRODUCTION: Acute angle between dome and ala causes alar concavity/pinch deformity. Breathing problems may accompany pinching. Here, pinch deformities were classified according to their severity and treatment modalities discussed. MATERIALS AND METHODS: Rhinoplasty patients with pinch deformities were included in study. Pinching without external nasal valve blockage (ENVB) was classified mild, pinching with ENVB was classified moderate, and extreme pinching and ENVB were classified severe deformity. In mild deformity, cephalic resection of ala was performed or cephalic resection was combined with onlay graft over ala. In moderate deformity, cephalic part was bent and sutured over lower ala. In severe deformity, cephalic part was bent, and lateral strut graft was inserted between lower and cephalic ala. In pinch deformities combined with hypertrophic lower lateral cartilage (LLC), medial crural overlay preceded above-mentioned treatment modalities. RESULTS: Thirty-eight patients (22 female, 16 male) with pinch deformities underwent rhinoplasty between January 2017 and December 2022. Mean age was 27 years. Mean follow-up was 32 months. Fifteen patients had mild deformities. Cephalic resection was enough in four patients. Camouflage grafts were settled over ala in eleven patients. Twenty patients had moderate deformities; cephalic ala was bent over lower part and sutured. Two patients had severe deformities; lateral strut graft was settled between lower and bent cephalic alar parts. One patient had LLC hypertrophy/pinch deformity. LLC hypertrophy was corrected by medial crural overlay, and concavity was corrected with cephalic resection. Satisfactory shape, better valve passage obtained in all cases. CONCLUSION: Pinch deformity could be classified according to its severity and appropriate treatment options could be determined for each class.

The effect of botulinum toxin application on latissimus dorsi and teres major muscles in patients with brachial plexus birth palsy: An electron microscopic and clinical study.

BACKGROUND: In brachial plexus birth palsy (BPBP), botulinum toxin may be utilized to prevent glenohumeral dysplasia and to maintain the stable growth of the glenohumeral joint. Repeated injections may cause muscular atrophy and their functional effects are uncertain. The aim of this study was to compare the microstructure and the function of the muscles that received two injections before transfer with the muscles that were not injected. METHODS: BPBP patients that were operated between January 2013 and December 2015 were included in the study. Latissimus dorsi and teres major muscles were transferred to humerus in standard fashion. Patients were divided in two groups according to bo-tulinum toxin status. Group 1 was toxin negative whereas Group 2 was toxin positive. For each patient, mean latissimus dorsi myocyte thickness (LDMT) was measured with electron microscopy and pre-operative and post-operative active shoulder abduction, flexion, external and internal rotation, and Mallet scores were evaluated with goniometry. RESULTS: Fourteen patients (seven patients per group) were evaluated. Five patients were female whereas nine were male. Mean LDMT was not affected significantly (p>0.05). The operation improved shoulder abduction, flexion, and external rotation significantly (p<0.05), independent of the toxin status. The internal rotation decreased significantly only in Group 2 (p<0.05). The Mallet score increased in both groups, but it was not significant (p>0.05), independent of the toxin status. CONCLUSION: Botulinum toxin that was applied twice prevented glenohumeral dysplasia and it did not cause permanent latissimus dorsi muscle atropy and function loss in late period. It augmented upper extremity functions by alleviating internal rotation contracture.

The predictive effect of neutrophil-lymphocyte and platelet-lymphocyte ratios in the post-operative recurrence of temporomandibular joint ankylosis.

BACKGROUND: Reankylosis is a frequent pathology in patients who are operated for post-traumatic temporomandibular joint (TMJ) ankylosis. In the current practice, ankylosing spondylitis attacks are monitored with the increases in neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR). In this study, such a relation between TMJ reankylosis and increase in these ratios was evaluated. METHODS: Patients who were operated between January 2010 and December 2019 for unilateral or bilateral TMJ ankylosis were included in this study. Temporomandibular gap arthroplasty with an interpositional silicone block was performed for each patient by the same operative team. Each patient had standard physiotherapy. All ages and genders were included in the study. Due to the complete blood count differences between children and adults, 18 years of age was used as a cutoff between the groups. A need for reoperation was accepted as reankylosis. The NLR and PLR of children without and with reankylosis and adults without and with reankylosis were compared. RESULTS: Twenty-nine children and 38 adults were included in the study. Mean age of the children and adults were 10.8 and 37.3 years, respectively. Eleven children and eight adults had reankylosis. In patients with reankylosis, NLR and PLR were high significantly, regardless of age. In children, PLR was significantly higher in reankylosis patients. In adults, NLR was significantly higher in reankylosis patients. CONCLUSION: PLR and NLR may be utilized for predicting reankylosis, respectively, in children and adults who were operated for ankylosis due to TMJ fractures.

Single axillary incision endoscopic surgery and liposuction for gynecomastia.

Gynecomastia is a common type of breast tissue hypertrophy in men. Surgical excision is the most effective treatment for this condition. Minimally invasive surgical techniques can be used to avoid visible chest scarring. In this study, we evaluated the efficacy and safety of single-axillary-incision endoscopic mastectomy and liposuction for the treatment of gynecomastia. Nipple-sparing mastectomy via a single-port axillary incision was successfully performed in all patients. Twenty-four bilateral procedures were performed in total. Twenty patients underwent liposuction concomitantly. The median weight of the mastectomy pieces was 88.5 g (range: 42.5-440 g), and the median amount of liposuction was 262.5 cc (range: 25-350 cc). The median duration of surgery was 120 minutes (range, 73-195 minutes). Two patients developed a seroma, and 1 patient developed a hematoma in the early postoperative period. The mean satisfaction levels related to physical appearance, mental status, and social environment were 8.75 (standard deviation [SD]: 1.19), 9.17 (SD: 1.44), and 9.33 (SD: 0.76) points, respectively, on a 10-point visual analog scale. Endoscopic single-port nipple-sparing mastectomy combined with liposuction is a technically feasible method to avoid anterior chest wall scarring with good cosmetic results. Between June 2021 and June 2022, 30 patients underwent endoscopic single-port nipple-sparing mastectomy through a small axillary incision, while 20 underwent concomitant liposuction. The demographic information of the patients, duration of surgery, amount of tissue removed, and complications were recorded. Patients' levels of satisfaction with their physical appearance, mental status, and social environment were measured.

Balancing the Anteroposterior Diameters of the Nostril Lengths in Cleft Rhinoplasty.

BACKGROUND: Osteocartilaginous deformities in cleft rhinoplasties may be restored with numerous techniques. However, the anteroposterior (AP) diameter lengths of the nostrils may still be unequal and should also be addressed. A technique was designed to balance nostril AP diameter lengths and apical shapes. MATERIALS AND METHODS: Balance between AP nostril diameters was accomplished by reduction of the AP diameter of the nostril at the non-cleft side by medial crural reduction and augmentation of the AP diameter of the nostril at the cleft side by three-parted mini-flap reconstruction at the soft triangle. The cleft-side AP diameter length was divided by the non-cleft-side AP diameter length of the same preoperative, per-operative and 1-year postoperative base view photographs of each patient, and "nostril balancing ratio" was obtained. The more this ratio was near to "one," the more the AP nostril diameters were equal. RESULTS: Seventy-eight unilateral-cleft rhinoplasty were performed between January/2019 and May/2022. Forty-two of them required nostril AP diameter equalization. Twenty-nine patients were female, thirteen were male. Thirty-three of them were operated for a primary cleft rhinoplasty. Nine of them for secondary cleft rhinoplasty. Mean age was 28 years (22-39 years). Mean follow-up was 25 months (6-40 months). The preoperative, per-operative and postoperative mean "nostril balancing ratios" were 0.714 (0.621-0.813), 0.743 (0.721-0.752) and 0.971 (0.943-0.976), respectively. CONCLUSION: Balancing AP diameter symmetry with MCO at the non-cleft side and three-parted mini skin flap reconstruction at the cleft side may provide the satisfactory results. Three mini-flaps at the soft triangle may remold the nostril apex in an oval shape, which may result in a better shape symmetry.

An Advantageous Donor Site Alternative for Preparing Crushed Cartilage Graft: The Postero-inferior Part of the Septal Cartilage.

Crushed cartilage is used in rhinoplasties and crushing carry the risk of devitalization. The most infero-posterior part of the septal cartilage has a rough surface compared with the smooth surface of the remaining parts. This cartilage may be more convenient for crushing with lesser pressure requirements, increasing the viability. Twenty-six patients underwent septorhinoplasty and the infero-posterior part of the septal cartilage was harvested. The rough cartilage was utilized in nine patients (excluded from the study). Seventeen patients were included in the study. The mean age of the patients was 28 (19-37y). Two pairs of grafts were utilized for histological study. In fifteen patients crushing experiment was performed. The smooth-surfaced cartilages were the control group, the rough-surfaced cartilages were the study group. For each case, grafts were reduced to the same dimensions and placed over millimetric-paper and photographed. The grafts were crushed simultaneously. The crushed cartilages were also placed on millimetric-paper and photographed. The data were evaluated statistically. The mean surface increment ratio was 2.26 ± 0.28 for the control and 2.94 ± 0.25 for the study group. The difference was statistically significant (p < 0.0048). In two specimen, after applying hematoxylin & eosin stain, the extracellular matrix of the rough cartilage specimen stained darker due to more abundant proteoglycan content. The rough septal cartilage widens more compared with the smooth cartilage under the same crushing pressure. Thus, the rough cartilage requires lesser pressure for widening which may increase the viability. The rough septal cartilage contains more proteoglycan which may explain its softness.

Technical Variations in the Management of the Medial Crural Reduction According to the Settlement of the Angulation Deformities Over Hypertrophic Lower Lateral Cartilages.

BACKGROUND: Medial crural (MC) overlay is reliable method used in tip deprojection. Most cases with lower lateral cartilage (LLC) hypertrophy present by variations of MC and dome shapes needing specific technical maneuvers. METHODS: Thirteen hundred fourteen primary rhinoplasties were performed between 2018 and 2021. Patients with LLC hypertrophy who underwent MC deprojection were analyzed. Three variations in LLC hypertrophy were recognized. In type I, tip-defining points (TDP) were localized at the median plane with no angulation deformities at the LLC, which was managed by horizontal cuts of the lobular segments 4 to 6 mm below the domes. The cut fragments overlapped for 2 to 5 mm. In type II, TDP was lateralized due to widened divergence angles at the columellalobular junctions, which were managed by horizontal cuts over columellalobular junctions. The cut fragments overlapped 4 to 6 mm. In type III, TDP was localized at the median plane, there were dense angulations at the medial genu, which was managed with symmetrical removal of 4 to 5 mm cartilage from lobular segments. The domes were sutured over the medial segments. RESULTS: Nineteen patients with LLC hypertrophy were included in the study among 314 patients. Twelve patients were female and 7 patients were male. The mean age was 32 years (25-42). Type I, II, and III LLC hypertrophies were detected in 10, 3, and 6 patients, respectively. A harmonious relationship between dorsum and tip and satisfactory tip stability was reached in all patients. CONCLUSIONS: By classification of variations of MC and domal shapes, LLC hypertrophies may be managed with proper technical maneuvers specific to each type.

Femoral artery aneurysm developed on intimal sarcoma: Case report.

Intimal angiosarcoma is a rare vascular malignancy, and diagnosis is very difficult due to nonspecific symptoms. There are controversial points regarding the diagnosis, treatment and follow-up of intimal angiosarcomas. The purpose of this case report was to evaluate the diagnosis and treatment process of a patient diagnosed with femoral artery intimal angiosarcoma. Furthermore, in line with previous studies, it was aimed to illuminate controversial points. A 33-year-old male patient, who had been operated on due to ruptured femoral artery aneurysm, was diagnosed with intimal angiosarcoma with the pathology result. Recurrence was observed during clinical follow-up, and the patient was treated with chemotherapy and radiotherapy. Since there was no response to treatment, the patient underwent aggressive surgery including the surrounding tissues. No recurrence or metastasis was observed in the patient's 10th month follow-up. Although intimal angiosarcoma is rare, it should be considered in differential diagnosis when femoral artery aneurysm is detected. The most important step in treatment is aggressive surgery, but adding chemo-radiotherapy to the treatment should be considered.

Post-traumatic double crush pudendal nerve entrapment syndrome after fracture of the pelvis: A case report.

Pudendal syndrome is primarily characterized by stress urinary incontinence, dysuria, sexual arousal syndrome, painful erections, and anal incontinence. The syndrome occurs when the pudendal nerve or one of its branches is compressed, stretched, or injured. Double crush is the compression of a peripheral nerve at two or more separate areas with various signs and symptoms. We, herein, aimed to introduce the case of a 42-year-old male who underwent the distal release procedure due to the diagnosis of "double crush pudendal syndrome" following a proximal release surgery previously performed elsewhere. The patient's history revealed a pelvic fracture with urethral injury 27 years ago. Throughout the years, the patient had been evaluated by various medical disciplines and undergone several treatments. In 2017, an orthopedic surgeon performed proximal pudendal nerve release using transgluteal approach, and then rectal pain and defecation complaints relieved. However, in 2019, the patient was referred to our clinic because of the persistence of erection and perineal complaints after the proximal pudendal nerve release. Based on a detailed clinical and laboratory assessment, the diagnosis of double crush neuropathy was established, and distal release of the pudendal nerve using transperineal approach was performed. To determine the efficiency of the surgical treatment, International Index of Erectile Function (IIEF) and Quality of Erection Questionnaire (QAQ) tests were used preoperatively and at the first postoperative year. Furthermore, to assess the perineal pain, erection pain, and pain during intercourse Visual Analog Scale (VAS) was used. The erectile dysfunction improved from the severe degree (9 points) to the mild degree (22 points) postoperatively. The patient's general and sexual satisfaction scores, and erection quality score improved compared to the preoperative baseline. According to VAS, the perineal pain, erectile pain,and pain during intercourse decreased postoperatively. (from 7 to 2 out of 10, from 8 to 3 out of 10, from 7 to 2 out of 10, respectively). When perineal and sexual complaints are encountered following pelvic trauma, the pudendal nerve-related problems, especially double crush syndrome, should be kept in mind in differential diagnosis. A multidisciplinary approach must be established in order to avoid any delay in diagnosis and treatment. Surgical intervention may provide a significant improvement in clinical and functional status.
