Correction of Temporal Hollowing Deformity Using Serratus Anterior Muscle Flap

Temporal hollowing deformity (THD) is a contour irregularity in the frontotemporal region, which results in facial asymmetry in the frontal view. Here, we present our clinical experience of correction of THD using serratus anterior (SA) muscle and fascia free flaps. Between March 2016 and December 2018, 13 patients presenting with THD were treated with SA free flap. The mean age of the patients was 47.8 years. The patients received craniectomy due to subarachnoid hemorrhage, epidural hematoma, or brain tumor. On average, correction of THD was performed 17 months after cranioplasty. The SA flap size ranged from 5 × 5 cm to 10 × 8 cm . The mean operation time was 107.3 minutes. All of the flaps survived without complications. The mean follow-up duration was 20.3 months. For correction of THD, the SA muscle and fascia flap is among the best candidates to permanently restore aesthetic form and symmetry.

Abstract Background The area which located at the medial pedicle, posterior vertebral body and ventral hemilamina is defined as the hidden zone. Surgical management of hidden zone lumbar disc herniation (HZLDH) is technically challenging due to its difficult surgical exposure. The conventional interlaminar approach harbors the potential risk of post-surgical instability, while other approaches consist of complicated procedures with a steep learning curve and prolonged operation time. Objective To introduce microscopic extra-laminar sequestrectomy (MELS) technique for treatment of hidden zone lumbar disc herniation and present clinical outcomes. Methods Between Jan 2016 to Jan 2018, twenty one patients (13 males) with HZLDH were enrolled in this study. All patients underwent MELS (19 patients underwent sequestrectomy only, 2 patients underwent an additional inferior discectomy). The nerve root and fragment were visually exposed using MELS. The operation duration, blood loss, intra- and postoperative complications, and recurrences were recorded. The Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and the modified MacNab criteria were used to evaluate clinical outcomes. Postoperative stability was evaluated both radiologically and clinically. Results The mean follow-up period was 20.95 ± 2.09 (18–24) months. The mean operation time was 32.43 ± 7.19 min and the mean blood loss was 25.52 ± 5.37 ml. All patients showed complete neurological symptom relief after surgery. The VAS and ODI score were significantly improved at the final follow-up compared to those before operation (7.88 ± 0.70 vs 0.10 ± 0.30, 59.24 ± 10.83 vs 11.29 ± 3.59, respectively, p < 0.05). Seventeen patients (81%) obtained an “excellent” outcome and the remaining four (19%) patients obtained a “good” outcome based the MacNab criteria. One patient suffered reherniation at the same level one year after the initial surgery and underwent a transforaminal endoscopic discectomy. No major complications and postoperative instability were observed. Conclusions Our observation suggest that MELS is safe and effective in the management of HZLDH. Due to its relative simplicity, it comprises a flat surgical learning curve and shorter operation duration, and overall results in reduced disturbance to lumbar stability.

Introduction: We report our experience with laparoscopic management of ureteropelvic junction obstruction in horseshoe kidneys.Methods: Between February 2004 and March 2014, 15 patients with horseshoe kidneys and symptomatic ureteropelvic junction obstruction underwent laparoscopic management at our national referral centre. Depending on the anatomy and presence of obtrusive vessels or isthmus, we performed either dismembered, Scardino or Foley YV pyeloplasty, or Hellstrom vessel transposition. Patients were initially evaluated by ultrasonography, then diuretic scintiscan at 4 to 6 months, and followed by yearly clinical and sonographic exams.Results: This study included 11 male and 4 female patients between the ages of 4 to 51 year (average 17.7). The left kidney was involved in 12 patients (80%). Operation time was 129 minutes (range: 90–186), and patients were discharged within 2.8 days (range: 1–6). Although 8 (53.3%) patients had crossing vessels, of which 6 required transposing, the Hellstrom technique was solely used in 3 cases, of which notably 1 case failed to resolve and required laparoscopic Hynes within the next year. Eight cases underwent dismembered pyeloplasty, 2 Foley YV, 1 Scardino flap and 1 required isthmectomy and vessel suspension. At the mean follow-up of 60 (range: 18–120) months, the overall success rate was 93.3%.Conclusions: To our knowledge, this represents the largest report on laparoscopic pyeloplasty for horseshoe kidneys, providing the longest follow-up. Our findings confirm prior reports supporting laparoscopy and furthermore show that despite the prevalence of crossing vessels, transposition alone is seldom sufficient.

Objectives: To evaluate the possible role of an hemostatic matrix on hemostasis, perioperative outcomes and complications in patients who underwent laparoscopic partial nephrectomy (LPN). Materials and methods: Patients charts were analyzed retrospectively and their demographic characteristics, operative parameters and follow-up results were recorded. Patients were divided into two groups, according to those who used an hemostatic matrix as Group 1 (n = 41) and those who did not used as Group 2 (n = 44). Demographic characteristics of patients, tumor features, operation time, clamping of the renal vessels, ischemia time, suturing of the collecting system, perioperative hemorrhage and complications were evaluated. Histopathological results, surgical margin status, creatinine level and recurrence at the 3rd month of follow up were analyzed. Statistical analyses were performed with SPSS 17.0 and significance was set at p value of < 0.05. Results: The mean RENAL nephrometry score was 5.9 ± 2.0 and the mean tumor size was 35 ± 12 mm. All patients had a single tumor and 44 of them had a tumor in the right kidney. The renal artery was clamped in 79 cases and the mean ischemia time was 20.1 ± 7 minutes. The mean tumor size and the mean RENAL nephrometry score was statistically higher in Group 1 (p: 0.016 and p < 0.001, respectively). Pelvicaliceal repair was more common in Group 1 due to deeper extension of tumors in this group (p: 0.038). In Group 1, less hemorrhage and blood transfusion requirement, with shorter ischemia and operation time was detected. Conclusion: The outcomes of the recent study showed that adjunctive use of an hemostatic matrix improves hemostasis and decreases hemorrhagic complications during LPN. Further prospective studies are required to assess the potential role of an hemostatic matrix in LPN.

Background Vascular occlusion after free flap surgery has become a rare complication but still poses a major challenge. It necessitates urgent re-exploration, but the logistic challenge to provide sufficient resources for the emergency intervention remains. The aim of this study was to analyze the long-term outcome after successful lower extremity free flap salvage. Methods A single-center retrospective study including long-term follow-up was approved by the local ethics committee. From January 1999 to December 2010, a total of 581 free flaps were performed for lower extremity reconstruction. Eighty-six flaps required emergency re-exploration, of which 65 could be salvaged. Fifteen salvaged flaps were excluded from the study because of secondary amputation. Of 50 patients, 29 (6 females and 23 males) were eligible for follow-up. The mean follow-up time was 54.5 ± 32.9 months. Health-related quality of life (Short Form 36 [SF-36]) and scar quality (Vancouver Scar Scale [VSS]) were analyzed. Results The overall flap survival rate was 94.7% and the total loss rate was 5.3%. The re-exploration rate was 14.8% (86 of 581 flaps). The salvage rate was 75.6% (65 of 86 flaps). Twenty-one free flaps were totally lost (24.4%). Partial flap loss occurred in 12 cases (14.0%); 67.5% of the vascular complications occurred during the first 24 hours, 20.9% between 24 and 72 hours, and 11.6% after more than 72 hours. The mean time from the first signs of impaired flap perfusion to re-exploration was 1.3 ± 0.4 hours, and from free tissue transfer to re-exploration was 16.2 ± 1.9 hours. The overall scar appearance was good with an average VSS score of 4.0 points. The average SF-36 physical component score was 54.4 ± 5.4 and the mental component score was 63.1 ± 10.7. Conclusion Careful monitoring and the opportunity for urgent re-exploration are the key to success for free flaps salvage. Following these principles, an acceptable long-term outcome can be achieved.

Background: Different laser types have been used for the treatment of hypertrophied inferiornasal turbinates. The clinical experiences of its treatment by means of a diode laser are presented.Methods: A total of 45 patients suffering from nasal obstruction due to hypertrophied inferiorturbinates (HIT) were treated with a continuous diode laser (14 W- 940 nm) in "contact" modeand under local anesthesia. Thirty patients (16 with allergic rhinitis and 14 with vasomotorrhinitis) were included into this clinical trial with a follow-up of 6 months. The study wasconducted by a questionnaire, photo documentation, conventional radiology of the paranasalsinuses, and histology.Results: The mean operation time took 8 min/turbinate, no nasal packing was necessary andno immediate complications (e.g., bleeding) were observed. Statistical analysis revealedsignificant subjective improvement (86%) of the nasal airflow and nasal cavity volume (photodocumentation) 6 months after laser surgery. In addition, complete relief of headache wasachieved in 32%. The remission rates of persistent rhinorrhoea and post-nasal dripping were,at about 88% and 64%, respectively. Atrophic change and synechiae had not been observed.Conclusions: Diode laser treatment of HIT is a useful procedure, which can be performed as anoutpatient surgery under local anesthesia, resulting in a controlled coagulation and ablation of thesoft tissue. The short operation time and the good results provide an excellent patient acceptance.Key words: Diode Laser; Hypertrophied Inferior Turbinate; Turbinoplasty.DOI: 10.3329/bjo.v16i1.5778Bangladesh J Otorhinolaryngol 2010; 16(1): 29-34

Different Levels

Lower extremity spasticity in CP interferes with daily living activities, such as ambulation and sitting as well as hygiene. Orthopedic surgery may be needed in the prevention and correction of the deformities and malalignments. Seven girls and nine boys with ages ranging from 7 to 17 years who had at least four surgeries at different levels of their lower extremities in a single stage were presented. Minimum follow-up was two years. The mean number of surgeries performed simultaneously was 6 (4 to 11). The mean operation time was 115 minutes (35 to 225 minutes) and the mean blood loss was 200 ml (100 to 600 ml) during surgery. The hospital stay ranged from two to six days. No complication which may be related to multiple simultaneous surgery was observed. Rehabilitation was begun as soon as the pain permitted. In the postoperative period, the diplegics attended sessions of hippotherapy — therapy by horse riding — in addition to formal therapy modalities. At the latest follow-up postoperatively, all the patients had increase in their level of activities. As a conclusion, whenever needed, simultaneous correction of the lower extremity deformities in spastic CP patients decreases costs and simplifies postoperative rehabilitation without increasing surgical risk for the patients.

Purpose: Dorsal metacarpal artery (DMA) flaps have been used successfully for distal dorsal finger defects. Some studies have reported inconsistent DMA anatomy, and there have been no studies on the anatomic variation of DMAs in Asian cadavers. Therefore, we evaluated the anatomy of DMA using Korean fresh cadavers and reported the clinical outcomes of the DMA flaps.Methods: In the cadaver study, four human forearms from adult fresh cadavers were dissected. The dorsal metacarpal arteries and their communicating branches were identified. From July 2016 to June 2019, five patients with dorsal finger defects underwent a first DMA (FDMA) flap or a reversed DMA (RDMA) flap.Results: In our cadaver study, the ulnar branch of the FDMA and the second and third DMAs were absent in two of four (50%) of the cadavers. In our case series, five flaps survived, and one had partial necrosis, which healed by the second intention. The mean operation time was approximately 100 minutes, and the mean outpatient follow-up period was 6 months.Conclusion: DMA flaps are a reliable flap for the reconstruction of relatively large soft tissue defects of the dorsal finger. However, in our anatomical study, inconsistency of the anatomy of DMAs was identified. Therefore, preoperative Doppler examination is required to evaluate the anatomy of the DMA before considering the use of DMA flaps.

Abstract Treatment of superomedially displaced acetabular fractures including a quadrilateral surface (QLS) is challenging. We present a surgical technique using an anatomical suprapectineal QLS plate through the modified Stoppa approach and report the availability of this plate to treat this fracture type along with the surgical outcomes. Thirteen consecutive patients (11 men and 2 women) who underwent surgical treatment using an anatomical suprapectineal QLS plate through a modified Stoppa approach for superomedially displaced acetabular fractures between June 2018 and June 2020, were enrolled retrospectively. These fractures included 10 both-column fractures and 3 anterior-column and posterior hemitransverse fractures, which were confirmed on preoperative 3-dimensional computed tomography. Surgical outcomes were clinically assessed using the Postel Merle d’Aubigné (PMA) score and visual analog scale (VAS) score at the final follow-up, and radiological evaluations were performed immediately after the operation and at the final follow-up. The follow-up period was longer than 1 year in all patients with a mean 22.9 months. The mean operation time was 103 min. Anatomical reduction was achieved in 11 (84.6%) patients, while imperfect reduction was achieved in the remaining two (15.3%) patients. At the final follow-up, radiographic grades were excellent, fair, and poor in 11 (84.6%), one (7.6%), and one patient, respectively. The mean PMA score was 16.3 (range, 13-18) and the mean VAS score was 1.0 (range, 0-3). No secondary reduction loss or implant loosening was observed. However, two patients underwent conversion to total hip arthroplasty due to post-traumatic arthritis and subsequent joint pain. No other complications were observed. Simultaneous reduction and fixation using an anatomical suprapectineal QLS plate through the modified Stoppa approach can provide satisfactory outcomes in superomedially displaced acetabular fractures, resulting in shorter operation times and fewer complications.
