Frontal Sinus Displacement of Silicone Implant After Previous Rhinoplasty.

Rhinoplasty, a historic surgical procedure for facial esthetics, has been actively performed in Asia. The use of autologous tissues or artificial materials, such as silicone, Gore-Tex, and Medpore, is common in achieving cosmetic improvements. However, artificial material poses risks of inflammation and foreign body reactions, leading to complications like infection and necessitating material removal and antibiotic treatment. According to previous reports, various clinical aspects appear across inflammation, skin necrosis, and, in severe cases, systemic symptoms caused by implants. In this case study, the goal is to share a rare case of silicone implant migration into the frontal sinus after augmentation rhinoplasty. A 38-year-old female patient who had previously undergone rhinoplasty surgery visited the outpatient clinic complaining of headaches and a deviated nose. On computed tomography, the silicone implant moved upward, penetrating the nasoethmoid bone and invading the frontal sinus. Fortunately, there was no intracranial invasion. The authors planned the implant removal and performed the complete implant removal with capsulectomy. The patient has been undergoing follow-up without any complications after surgery. Augmentation rhinoplasty with implants, while common, carries long-term risks. This case highlights the severity of complications, emphasizing infection and migration into the frontal sinus and, in extreme cases, the brain cavity. Therefore, surgeons must continually refine operation techniques to minimize iatrogenic causes and consider modifying surgical procedures to prevent potential complications.

Transverse division of the rectus abdominis muscle in deep inferior epigastric perforator flap elevation: A rescue technique to include more than one perforator.

BACKGROUND: It is important to include as many perforators as possible in order to enhance the vascularity of a deep inferior epigastric perforator (DIEP) flap. However, the rectus muscle must be transected transversely, which prevents suturing and can cause a defect along the same line as the muscle-sparing procedure. When harvesting the DIEP flap, no specific method was suggested to solve these muscle defects. We found that by transecting the rectus muscle transversely, the muscle could be sutured in the tendinous area more easily while maintaining muscle function. The purpose of this study is to confirm the long-term recovery of the rectus abdominis muscle through the volume change after DIEP flap using this tendinous transection and suture method. PATIENTS AND METHODS: A retrospective review of 28 patients who underwent unilateral breast reconstruction using a DIEP flap and the tendinous transection method for multiple perforators between May 2018 and April 2020 was conducted. The preoperative and postoperative volumes of the rectus abdominis muscle were estimated both the harvest and opposite sides. RESULTS: The preoperative and postoperative muscle volumes from the harvest side were 50.08 ± 8.71 cm3 and 48.56 ± 8.61 cm3, respectively. The volume difference was 1.522 cm3 decrease, which was not statistically significant (p = .070). The preoperative and postoperative muscle volumes from the opposite side were 50.50 ± 8.15 cm3 and 50.08 ± 8.18 cm3, respectively. The volume difference was 0.434 cm3 increase and was not statistically significant (p = .064). Postoperative volume changes in the rectus muscle were not statistically significant on either side. CONCLUSION: The tendinous transection method in the DIEP flap procedure did not significantly affect postoperative rectus muscle volume. Therefore, we expect this harvest method to allow DIEP flap reconstruction that includes multiple perforators and complete donor muscle recovery.

The cover of an ear thermometer probe as a split-thickness skin graft mold in external auditory canal reconstruction.

Maintaining the patency of the external auditory canal (EAC) during reconstruction is important because of its physiological role in hearing and immunological protective functions. The curved shape of the EAC presents a challenge when performing a skin graft. One of the key points for a successful skin graft is to ensure compression on the wound bed, and many novel methods, including prefabricated ear molds, have been reported for this purpose. In this study, we present a case of a skin graft performed to reconstruct a skin defect following excision of actinic keratosis in the EAC, using the cover of an ear thermometer probe as a mold for the graft to match the curvature of the EAC. This is an economical and practical method for secure compression dressing of a skin graft in the EAC.

The Effect of Steroid and Mannitol Combination Treatment on Postoperative Rehabilitation of Multiple Metacarpal Bone Fractures.

Background and Objectives: The expedient resolution of postoperative soft tissue edema is particularly important in hand surgery. Prolonged edema and pain become an obstacle to postoperative rehabilitation, delay return to daily life, and in severe cases, lead to a permanent decrease in range of motion. Based on the common physiology between postoperative hand swelling and complex regional pain syndrome (CRPS), we sought to determine if postoperative mannitol and steroid administration to multiple metacarpal bone fracture patients effectively reduces hand swelling and pain and is beneficial for hand rehabilitation. Materials and Methods: From March 2015 to February 2019, 21 patients who received closed pinning for multiple metacarpal fractures were included in a retrospective cohort study. The control group (n = 11) underwent a routine recovery, while the treatment group (n = 10) received dexamethasone and mannitol injections for five days postoperatively. Serial changes in the degree of pain and fingertip-to-palm distance (FPD) were measured in both groups. The duration from surgery to the initiation of rehabilitation and time to full grip was also compared. Results: Compared to the control, the treatment group showed a faster alleviation of pain scores from the postoperative fifth day (2.91 versus 1.80, p = 0.013), and faster recovery of FPD from postoperative two weeks (3.27 versus 1.90, p = 0.002). Time to physical therapy initiation (6.73 versus 3.80 days, p = 0.002) and full grip achievement (42.46 versus 32.70 days, p = 0.002) were also faster in the treatment group. Conclusions: The steroid-mannitol combination treatment for multiple metacarpal bone fracture patients in the acute postoperative phase promoted the reduction of hand edema and pain, leading to the earlier initiation of physical therapy, rapid improvement in joint motion, and faster achievement of full grip.

Flipped Nasal Bone Fracture: Peculiar Fracture Pattern in a Pediatric Patient.

Fractures to the facial bone in the pediatric population often show a different fracture pattern from that of the adult population. In this brief report, the authors share their experience with a nasal bone fracture in a 12-year-old child showing a bizarre fracture pattern, an inside-out displacement of the nasal bone. The authors share the detailed findings of this fracture and describe the method for reducing the fracture back to the proper position.

Anterior-First Approach for Latissimus Dorsi Myocutaneous Flap Breast Reconstruction: A Refined Elevation Method with Detailed Video Instructions.

Background: The latissimus dorsi myocutaneous (LDMC) flap is a preferred flap in breast reconstruction for its wide surface area and volume. Since the flap is situated in the midback area, a lateral decubitus approach is a conventional method. However, proper visualization and access to the thoracodorsal vascular pedicle or muscle insertion is difficult from the lateral approach, causing inefficiency and surgeon fatigue. We propose the 'anterior-first' approach in LDMC flap reconstruction, where the landmark structures are first approached from the supine-anterior position through the mastectomy incision. Methods: From January 2014 to December 2020, 48 patients who received immediate breast reconstruction with LDMC flap were included in the study. Patients received reconstruction with the conventional approach (n = 20), or anterior-first approach (n = 28). Demographic factors and the operative outcomes were retrospectively analyzed and compared between the two groups. Results: Compared to the conventional approach group, the anterior-first approach group showed improved efficiency in the duration of total reconstruction (228 versus 330 min, p < 0.001), and flap elevation (139 versus 200 min, p < 0.001). No difference in complication rate and time to drain removal was observed (p = 0.14 and >0.9, respectively). Conclusion: The anterior-first approach for breast reconstruction with LDMC flap provides surgeons with an enhanced surgical exposure and superior ergonomics, leading to a safer and more efficient flap elevation.

Ectopic Breast Tissue in the Inguinal Region: A Case Report and Suggestion of Indications for Excision.

We report a rare case of ectopic breast tissue situated in a unique location. A 50-year-old female patient came to our institution complaining of a bulge in the inguinal area. CT was unremarkable other than a benign-looking conglomeration of lymph nodes around the inguinal canal. However, excisional biopsy proved otherwise, with strong expression of breast-related immunohistochemical markers on pathology. Based on histological findings, the diagnosis of ectopic breast tissue was made. Since the vast majority of ectopic breast tissue is found around the breast mound, axilla, and along the milk line, this case is peculiar in its location. This report shares our experience and provides indications for excision of incidental ectopic breast tissue.

Apocrine tubular adenoma on the palm: A case report.

RATIONALE: Tubular apocrine adenoma (TAA) is a very rare benign neoplasm of the apocrine gland. The typical anatomical locations are mostly hair-bearing areas, where normal apocrine glands are abundant. PATIENT CONCERNS: We report the case of a 40-year-old patient with a tubular apocrine adenoma on a non-hair-bearing area. DIAGNOSES: Ultrasonography showed a 0.4-cm-sized hypoechoic nodule in the subcutaneous plane of the left palm at the fourth carpometacarpal joint level. INTERVENTIONS: Surgical resection was performed and histopathological examination revealed lobules of well-differentiated dilated tubular structures at the dermis level. OUTCOMES: At 1 year of postoperative follow-up, the patient was completely recovered without signs of recurrence. LESSONS: Diagnosis of TAA can be misleading due to its unusual location and inconspicuous appearance. Immunohistochemistry for epithelial membrane antigen and gross cystic disease fluid protein-15 is crucial for the proper diagnosis. Complete excision is recommended to prevent recurrence.

Delayed periprosthetic seroma in a male Poland syndrome patient: A case report.

RATIONALE: Custom-made implant is an accepted treatment option for treatment of chest deformity in Poland syndrome. Unlike the raised concerns and awareness for the long-term consequences of breast implants, the long-term complications of customized implants for special purposes like Poland syndrome has not been reported in the literature. PATIENT CONCERNS: A 44-year-old male with Poland syndrome presented to our institution complaining of a large bulge and fluctuation on the right chest wall. This occurred after 14 years from the initial implant surgery for correction of chest wall deformity. Upon failure of resolution by multiple aspirations, workup was carried out under suspicion of implant associated malignancy. INTERVENTION: Total Capsulectomy and implant removal was done. OUTCOMES: Histology revealed chronic inflammation with fibrosis. Implant-associated malignancy was not found. He is being followed up with no signs of recurrence. LESSONS: For rare cases of implant insertion such as Poland syndrome, awareness of delayed complications and workups based on suspicion of implant-associated malignancy is needed. Surgeon awareness and patient education is required.

Verapamil-containing silicone gel reduces scar hypertrophy.

A hypertrophic scar is a common dermal fibroproliferative lesion usually treated with topical silicone. Verapamil, a type of calcium channel blocker, is considered a candidate drug for the treatment of hypertrophic scars. Here, we report that the addition of verapamil to topical silicone gel enhances treatment outcomes of hypertrophic scars. Upon creation of hypertrophic scars with the rabbit ear model, varying concentrations of verapamil-added silicone gel (0.1, 1, and 10 mg/g) were applied daily for 28 days. After the animals were euthanised, microscopic measurement was performed for (a) scar elevation index (SEI), (b) fibroblast count, and (c) capillary count. On gross analysis, features of hypertrophic scars were significantly alleviated in the verapamil-added groups. On histologic examination, verapamil-added groups showed (a) reduced SEI (1.93 (1.79-2.67) for control vs 1.34 (1.21-1.51) for silicone only and 1.13 (1.01-1.65) for verapamil-added silicone), (b) fibroblast count 700.5 (599.5-838.5) for control, 613.25 (461-762.5) for silicone only, and 347.33 (182.5-527) for verapamil-added silicone), and (c) capillary formation (52 (35.5-96.5) for control, 46 (28-64.5) for silicone only, and 39.83(24-70) for verapamil-added silicone) (Kruskal-Wallis test, P < .05). On western blot, expression levels of collagen I protein was lower in the 1 mg/g and 10 mg/g verapamil-added silicone compared with control. Therefore, we suggest a therapeutic concentration of verapamil-added silicone gel of at least over 1 mg/g. Further study regarding maximally effective concentration and deeper insight into the mechanism of action should follow.

Central Nervous System Solitary Fibrous Tumor/Hemangiopericytoma Penetrating the Skull Bone: An Unusual Presentation.

BACKGROUND: Central nervous system (CNS) solitary fibrous tumor/hemangiopericytoma (SFT/HPC) is a soft tissue neoplasm that accounts for <1% of all intracranial tumors. Its growth will be mostly intracranial, usually along the sinuses. We have reported a rare case of direct extracranial extension of CNS SFT/HPC penetrating the frontal bone. CASE DESCRIPTION: A 64-year-old woman had visited our institution for treatment of a forehead mass. With the impression that it was a subcutaneous mass, we had planned a simple excision with the patient under local anesthesia. However, the intraoperative findings showed extension of the mass into the skull and attachment to the dura mater. Brain magnetic resonance imaging showed a 1.8-cm solid mass with an adjacent skull defect, and examination of the biopsy specimen confirmed the diagnosis as grade II CNS SFT/HPC. Definitive excision was performed by en bloc tumor resection with a 2-cm safety margin. Adjuvant radiotherapy was performed with 60 Gy in 30 fractions. The patient showed no signs of recurrence or metastasis during 2 years of follow-up. CONCLUSIONS: The present case has shown that CNS SFT/HPC can infiltrate the full thickness of the skull bone and grow extracranially, even if low grade. However, the unusual presentation of the present made early exploration and total resection possible.

Acellular dermal matrix (Insuregraf) in the prevention of Frey's syndrome and surgical site depression after parotidectomy.

BACKGROUND: Parotidectomy is the treatment of choice in many parotid tumors. Due to the extensive nature of the procedure, unfavorable complications such as gustatory sweating, surgical site depression are common. Various techniques using fascia, muscle or AlloDerm have been developed but debate still remains regarding its availability and affordability. We applied a newly developed acellular dermal matrix (Insuregraf) to the parotidectomy field to act as a physical barrier and to provide adequate filling effect for prevention of functional and aesthetic complications. METHODS: From March 2010 to March 2017, 30 patients with parotid tumors underwent superficial parotidectomy. Twenty patients underwent only superficial parotidectomy. Ten patients had Insuregraf applied to the surgical site after superficial parotidectomy. We evaluated the incidence of Frey's syndrome, surgical site depression, and patient satisfaction rate in both groups. RESULTS: The incidence of Frey's syndrome was lower in the Insuregraf group (0 vs. 2). Surgical site depression was also lower in the Insuregraf group (2 vs. 20). Satisfaction score for facial contour in Insuregraf group was 9.2 out of 10, which was comparable to 6.2 out of 10 in the control group. CONCLUSION: Application of Insuregraf after superficial parotidectomy is an effective surgical procedure to prevent complications such as Frey's syndrome and surgical site depression. This technique is affordable and safe with no immune reactions. Above all this surgical method should be considered as an option for patients who are concerned about the contour of the face after surgery.

Simultaneous Forehead Lift and Blepharoplasty Techniques in Management of Orbito-Temporal Plexiform Neurofibroma.

Plexiform neurofibromas are common complications in neurofibromatosis type 1 patients. Currently, surgery is the treatment of choice. However, complete surgical resection is difficult due to the infiltration to the surrounding tissue and the increased vascularity. Plexiform neurofibromas arising in the orbito-temporal area pose a greater challenge due to its critical function and cosmetic importance of the face. Such plexiform neurofibromas, separately designated as orbito-temporal plexiform neurofibromas, show complex symptoms such as severe ptosis, ectropion, lacrimal gland dysfunction, and even vision loss. We present a case of successful correction of upper eyelid entropion and severe eyebrow ptosis in a 48-year-old orbito-temporal plexiform neurofibromas patient with combined forehead lift and blepharoplasty techniques including double fold formation and mass excision.

Three-Surface Reconstruction Using Single De-Epithelialized Radial Forearm Free Flap.

Head and neck cancer often requires multiple defect reconstruction that are too far apart to handle with 1 flap. However, 1 flap with skin graft, or multiple flap reconstruction is always not possible due to recipient site factors and lack of sufficient donor site. In this report, we share our experience on reconstruction of multiple, and distant head and neck defects with 1 large radial forearm flap that was vertically inset to cover multiple defect on face, and then tunneled to reach down to the neck. Due to the longer dimension, this flap could be utilized not only to reconstruct the face and neck area, but also simultaneously reconstruct face and orbit, or face and scalp area. We think that this modification of the radial forearm flap could provide a useful surgical option for multiple and distant head and neck reconstructions.

Pediatric follicular lymphoma of the parotid gland.

Primary malignant lymphoma rarely presents as a mass in the salivary gland. It accounts for about 1% of salivary gland tumors. The lymphomas of the parotid gland are mainly non-Hodgkin's lymphoma of B-cell follicular type. It usually occurs in male adults and is very rare in children. In contrast to the intractable disease course of adult parotid follicular lymphoma, when occurred in children or adolescent, its prognosis is very good when it is first treated with surgical excision. Thus, a solitary follicular lymphoma in an extranodal site that has occurred in children is termed separately as pediatric follicular lymphoma (PFL). We share our treatment experience of a 16-year-old PFL patient through surgical removal combined with superficial parotidectomy. In line with the few previous case reports of PFL, we suggest that active surgical removal should be undertaken for solitary, extranodal follicular lymphoma of the pediatric and adolescent population.

Feasibility of a deepithelialized superior gluteal artery perforator propeller flap for various lumbosacral defects.

Skin and soft tissue defects in the lumbosacral area are commonly encountered in the field of reconstructive surgery, and it is well documented that the superior gluteal artery perforator (SGAP) flap provides excellent coverage of these defects. In this article, we describe our experience using a modified version of the SGAP propeller flap, in which the distal redundant portion of an elevated SGAP flap is deepithelialized, thereby maximizing the effect of the soft tissue augmentation. Thirteen patients with lumbosacral soft tissue defects treated between May 2010 and June 2012 were included in this study. The wound causes were pressure ulcer (n = 9), pseudomeningocele (n = 2), and hardware exposure (n = 2). In all patients, an elevated SGAP flap was rotated 180 degrees over the defect area and the extra distal portion of the flap was deepithelialized and used as a soft tissue filler or tamponade. During the follow-up period (mean, 26 months), 12 of 13 flaps survived completely. One flap was totally necrosed due to progressive venous congestion and was reconstructed with local advancement flaps. No further complications were noted. Because of the redundancy and pliability of the tissue in the gluteal area, a flap relatively wider or longer than the defect can be elevated safely. Hence, the redundant tissue volume can be tucked inside to facilitate soft tissue augmentation of the area. We propose that the deepithelialized version of the SGAP propeller flap is an effective option for the reconstruction of various lumbosacral soft tissue defects because it offers thick and healthy soft tissue from a distant site to the defect areas.
