RESUMEN
PURPOSE: Defects involving total lower and/or upper lip often extend to intraoral and/or perioral areas. Flaps based on superficial temporal artery, either as pedicled or free flaps, can be used for reconstruction of various head and neck defects. In this clinical study, we tried to demonstrate the application of a pedicled flap based on the posterior branch of superficial temporal artery in 3-dimensional reconstruction of these composite oral/perioral defects as a successful alternative in cases where microvascular tissue transfer cannot be performed. PATIENTS AND METHODS: Six male patients with composite perioral/oral defects who underwent reconstruction with a pedicled flap based on the posterior branch of the superficial temporal artery between April 2020 and December 2020 were evaluated retrospectively. Demographic data, topographic data of defects, and the dimensions of the flaps were gathered from patient files. All patients required reconstruction after tumor resection. RESULTS: All flaps survived without any signs of partial or total necrosis. Postoperatively, the patients did not report any oral incompetence or drooling, and they were able to fully close their mouths. CONCLUSIONS: Pedicled flaps based on the posterior branch of superficial temporal artery provide reliable results in composite perioral/oral reconstruction.

BACKGROUND: In the light of the results of recent randomised controlled trials regarding the role of nodal observation and completion lymph node dissection (CLND), studies from different populations are needed. The aim of our study was to present our experience with sentinel lymph node biopsy (SLNB) and CLND and the clinical and histopathological factors associated with a positive non-sentinel node. METHODS: In this single-centre, retrospective study, we reviewed histopathological reports of patients with primary cutaneous melanoma who underwent SLNB and CLND over a period of 7 years. The primary outcomes were the positivity rates of SLNBs and CLNDs. Secondary outcomes were metastatic tumour burden in positive sentinel nodes and presence of perinodal invasion. RESULTS: Among the 110 participants who underwent SLNB (53 females, 57 males), the mean Breslow thickness of the primary tumour was 4.1 (0.3-41) mm. Ulceration appeared in 62.7% of lesions. The SLNBs were positive in 38 patients (34.5%), with 35 (92.1%) undergoing CLND, among which 9 (25.7%) showed metaNBstasis. Positive SLNB was linked to a higher Breslow thickness (p = 0.022), whereas CLND results lacked such an association (p = 0.76). Perinodal invasion (p = 0.006) and sentinel lymph node metastasis exceeding 1 mm (p = 0.017) was associated with a higher probability of non-sentinel node metastasis. CONCLUSION: To adapt the results of the new cohort study on SLNB and melanoma to different populations, studies with different patient groups highlighting the problems and suggested solutions are needed.

Implanted deep brain stimulation (DBS) devices are crucial in the treatment of movement disorders. Hardware extrusion is among the most frequent complications of the implantation process and requires reconstruction with well-vascularized tissues. The authors present a case of periosteal turnover flap for coverage of an exposed DBS device. An 11-year-old female patient with spastic cerebral palsy presented with an exposed DBS device located in the right parietal area. The exposed device was covered by a proximally based periosteal flap. Postoperative evaluations at months 1, 2, 3, and 8 revealed no signs of infection or dehiscence. This brief clinical study shows that reconstruction with periosteal turnover flaps is both an easy and excellent choice for secondary closure of exposed DBS devices.

It has been established that many chemotherapeutic agents are associated with a variety of ocular side effects. As an antineoplastic agent, 5-fluorouracil (5-FU) is the chemotherapeutic agent that is frequently linked with cicatricial ectropion. Capecitabine is a prodrug of 5-FU and has a more favorable side effect profile than 5-FU. Frequent side effects of capecitabine include gastrointestinal events and hand-foot-mouth syndrome; cicatricial ectropion is rather uncommon. Enzyme deficiencies affecting the capecitabine metabolism have been reported to be associated with exaggerated generalized systemic and cutaneous side effects; however, there are no cases in the literature reporting capecitabine-induced isolated bilateral-progressive ectropion. Although cessation of the agent is frequently sufficient for the treatment of ectropion, close follow-up is indicated in such patients as permanent damage may occur if the problem is left untreated. We report a case of capecitabine-induced bilateral cicatricial ectropion refractory to treatment cessation, ultimately requiring surgical treatment.
