Background/Aim. Surgeons often face with the problem when selecting a reconstructive method for nasal skin defects. The aim of this study was to determine functional and aesthetic characteristics of different reconstructive methods used for skin defects in different regions of the nose. Methods. The study involved 44 patients with basocellular carcinoma in nasal area. The nasal skin was divided into four subunits: the tip, the alar lobules, the side-walls and the dorsum. The average skin defect size was 10 mm in diameter. Local flaps and full thickness skin grafts were used in the study. We analyzed the functional and esthetic results of different reconstructive methods used for nasal defects in different regions of the nose 12 months after the surgery. Results. The study shows that different reconstructive methods produce different functional and esthetic results in the same nasal subunits and that the same reconstructive method produces different results in different nasal subunits. Conclusions. Estimation the postoperative functional and esthetic characteristics of different reconstructive methods is one of the basic preconditions of successful reconstruction. © 2016, Institut za Vojnomedicinske Naucne Informacije/Documentaciju.

Basal cell carcinoma (BCC) is one of the most common malignant tumors in human medicine and the most common skin malignancy, with the largest number of lesions found on exposed parts of the skin, on the face, head, and neck. The average age of the patients is 60 years, with an increasing incidence in younger ages and an increased incidence in males. The incidence of BCC is increasing and doubles every 25 years. Annually, there are approximately 1,000,000 newly diagnosed cases worldwide. The frequency of malignant skin tumors depends on the influence of external factors such as ultraviolet radiation and other biological properties of the skin with a higher incidence in fair-skinned people (Fitzpatrick type I and type II skin types). BCC is a slow-growing malignant tumor that arises from the basal layer of the epidermis, the outer layer of hair follicles, or the sebaceous glands. BCC can be locally invasive and, if neglected, can infiltrate surrounding structures (muscles and cartilage) and vital structures, which can ultimately lead to death. The clinical presentation is very diverse and dependent on the histological subtype. Prevention is the most important and effective approach towards reducing the burden of BCC. The best treatment for BCC is surgical excision with confirmation and verification of surgical margins. The therapeutic goal is oncologic radical resection of the tumor, followed by reconstruction of the affected area for structure and optimal aesthetic result. © 2023, Serbia Medical Society.

Introduction: Chondroblastoma is a rare, benign mesenchymal tumor that can behave local aggressive. It most often occurs in the area of the epiphyses of long tubular bones, whereas the appearance in the region of the head and neck is rare, only few reports were published in literature. The incidence of chondroblastoma of the craniofacial region is about 6.4%. Clinical Report: A 46-year-old patient was hospitalized due to growth and pain in the area of the left half of the face, and a tumor of the left infratemporal fossa was diagnosed by computed tomography. The patient was operated with a preauricular surgical approach, parotidectomy, and complete tumor removal was performed. Pathohistological examination revealed chondroblastoma. Conclusions: Chondroblastoma of the craniofacial region is very rare pathohistological finding, characterized by slow and asymptomatic growth until it reaches the appropriate dimensions, the clinical symptomatology depends on the localization of the tumor. Computed tomography diagnostics provides important information about the location, size of the tumor, invasion of surrounding structures, and significantly contributes to the decision on the appropriate surgical approach.

Introduction: Sarcomas are relatively rare malignant tumors of mesenchymal origin, representing only about 1% of tumors in the head and neck region. Materials and Methods: A retrospective study involved patients with sarcomas of the head and neck region who were diagnosed and treated over a 5-year period. Results: Nine patients were included, 4 men and 5 women. The mean age of the patients was 51 years. Eight patients had soft tissue sarcomas, and 1 patient had osteosarcoma. The most common histologic types were dermatofibrosarcoma protuberans and angiosarcoma. Tumors presented predominantly with local symptomatology. All patients were treated only by surgical excision. No distant or regional metastases were found in any patient. Complete surgical excision was achieved in all cases, except in patients with chondrosarcoma of the nose and sinuses, who died due to local progression in the second year of follow-up. Other patients were disease-free during the observed period; a patient with osteosarcoma died in the fourth year of follow-up without recurrence of the malignant disease. Conclusion: Large prospective and multicenter studies are necessary to provide relevant data on the distribution of different types of sarcoma in the head and neck region, their clinical behavior and response to therapeutic modalities, as well as on recurrence, presence of metastases, and survival.
