Pedicled anterolateral thigh flap phalloplasty combined with radial forearm free flap urethral reconstruction in gender-affirming surgery: a report of two cases

Kuylhee Kim,Donghyun Lee,Soyeon Jung,Chul Hoon Chung,Yongjoon Chang 대한수부외과학회 2023 대한수부외과학회지 Vol.28 No.4

This case report presents two female-to-male (FTM) patients, aged 21 and 35 years, respectively, who underwent phalloplasty and urethral reconstruction at our institution. The patients’ requests included a phallus >9 cm, concealed donor-site scars, and the ability to void while standing. In the first case, a 4.5×13-cm radial forearm free flap (RFFF) taken from the nondominant side was retrieved and anastomosed to the deep inferior epigastric artery and vein. Simultaneously, a 10×16-cm pedicled anterolateral thigh (ALT) flap was relocated to the genital area and wrapped around the RFFF after nerve coaptation. The second case involved a 5.5×14-cm RFFF and a 20×13-cm pedicled ALT flap using a similar procedure. Both cases had stable double flaps with no complications, and Foley catheters were removed at 14 days and 3 months after surgery, respectively. Double-flap phalloplasty is thus a viable option for patients with a short forearm circumference or a preference for a less visible forearm scar.

A 76-year-old woman, initially thought to have a simple abscess on her right upper eyelid, presented to our department of plastic and reconstructive surgery. Enhanced three-dimensional facial computed tomography (CT) revealed an abscess on the right upper lid, with a pyomucocele present in the right frontal sinus, accompanied by bone erosion in the superior wall of the right orbit. Based on the results of the CT scan, we diagnosed an atypical Pott's puffy tumor (PPT) with an abscess on the upper lid originating from the frontal sinusitis. First, surgical incision and drainage were performed in our department, and a percutaneous vacuum drain was placed. To provide a more definitive treatment, endoscopic sinus surgery (ESS) was subsequently performed by otorhinolaryngologists. The patient was discharged without any complications 5 days after ESS. At a 1-year follow-up, no recurrence or notable neurological symptoms were observed. In the case we observed, the patient presented with an upper eyelid abscess and cellulitis, indicating possible orbital involvement. For such patients, a CT scan is necessary. Given the possibility of PPT, it is critical to perform a comprehensive differential diagnosis rather than defaulting to a straightforward approach involving abscess treatment.

드물게 발생한 얼굴 연조직의 점액섬유종에 대한 증례보고

Myxoma is a locally invasive neoplasm usually involving the jaw bones, typically occurs between the second and fourth decades. This tumor may comprise 3%-6% of odontogenic tumors. Myxomas of the soft tissue of the face are very rare. We present an unusual case of myxofibroma occurring in a 13-year-old man involving the soft tissue of the face. It congenitally occurred and was a 1 cm sized, ovoid in shape, swelling located on the glabella without any symptoms. An excisional biopsy was performed. A well encapsulated ovoid mass was attached to the corrugator supercilli muscle below the frontalis muscle. It was measured 1.1 x 1 x 0.8 cm and completely excised. Histological examination revealed myxofibroma showing stellate and spinde-shaped cells throughout myxoid ground substance. The unusual features of this case are the site of the tumor, which was localized to the non-tooth bearing area of the mandible and its congenital occurrence history.

Nail growth disorder in multiple fingers following harvesting of radial forearm free flap for phalloplasty in gender-affirming surgery: a case report

Nail growth disturbance commonly takes place after trauma or relevant diseases, such as infections and tumors. However, abnormal growth of the nail plate sometimes occurs without an obvious causative factor. This report presents the case of a patient who underwent male genital reconstruction with a radial forearm free flap for gender affirmation. Although the entire process was smooth, with no accidental events, the second, third, and fourth phalangeal nail plates of the hand from which the flap was harvested showed no evident growth of the fingernail 2 months postoperatively. Nail production was preserved in the remaining fingernails. Typical symptoms, such as redness, swelling, and tenderness, were noted upon clinical observation. Eventually, nail production restarted 5 months after surgery. Steroid and antibiotic treatment was attempted to reduce periungual inflammation. Additionally, close observation with psychological support was conducted.

Surgical treatment of high-pressure injection injuries of the hand caused by using paint guns: a report of three serial cases

Jiwon Jeong,Chul Hoon Chung,Yongjoon Chang,Kuylhee Kim,Soyeon Jung 대한수부외과학회 2024 대한수부외과학회지 Vol.29 No.1

The incidence of high-pressure injection injuries is increasing with the development of industry and use of injectors. Although high-pressure injection injuries are relatively rare, they commonly lead to complications such as skin necrosis, infection, and amputation. Moreover, the initial presentation is prone to be underestimated because of the small entry point at the patient’s first encounter in emergency care. A prompt surgical intervention is required, with appropriate and rapid initial treatments, including broad-spectrum antibiotics and tetanus toxoid. The surgical treatment involves wide debridement for foreign material removal and subsequent reconstruction. In this case report, we present three cases we encountered and the ensuing complications. All three patients who received the same treatments are discussed in detail.

A computed tomography-based analysis of the structure of the mandible according to age and sex

Jung, Soyeon,Yun, Hyunjong,Chung, Chul Hoon,Kim, Kuylhee,Chang, Yongjoon Korean Cleft Palate-Craniofacial Association 2022 Archives of Craniofacial Surgery Vol.23 No.3

Background: The primary objectives of mandibular surgery are to achieve optimal occlusion, low sensory disturbance, and adequate fixation with early movement. In-depth knowledge of the mandibular structure is required to achieve these goals. This study used computed tomography (CT) to evaluate the mandibular cortical thickness and cancellous space according to age and sex. Methods: We enrolled 230 consecutive patients, aged 20 to 50 years, who underwent CT scanning. The cortex and cancellous space centered around the inferior alveolar nerve (IAN) canal were measured at two specific locations: the lingula and second molar region. Statistical analysis of differences according to increasing age and sex was performed. Results: The t-test revealed that the cancellous space and cortical thickness differed significantly with respect to the threshold of 35 years of age. Both cortical thickness and cancellous space in the molar region were negatively correlated with age. Meanwhile, both cortical thickness and cancellous space in the lingula region showed a positive correlation with age. With respect to sex, significant differences in the cancellous space at the molar region and the cortical thickness at the lingula were observed. However, no further statistically significant differences were observed in other variables with respect to sex. The sum of each measurement on the mandibular body reflected the safe distance from the surface of the outer cortex to the IAN canal. The safe distances also showed statistically significant differences between those above and below 35 years of age. Conclusion: Knowledge of the anatomical structure of the mandible and of changes in bone structure is crucial to ensure optimal surgical outcomes and avoid damage to the IAN. CT examination is useful to identify changes in the bone structure, and these should be taken into account in the planning of surgery for older patients.
