Carcinomas of the nasal cavity and paranasal sinuses represent a rare entity, accounting for less than 3% of all tumors of the head and neck region. Within this group, carcinomas of the nasal cavity are by far the smallest fraction. The rarity and the localization in a transitional area between different anatomical regions, pose a particular challenge concerning the diagnosis and treatment of these malignancies. In this work, we would like to present our experience based on a case series of 34 patients with nasal cavity carcinomas who were treated in our ENT clinic from 2014-2023. Of these patients, two-thirds were male and one-third female. The age at initial diagnosis ranged from 40 to 82, with an average age at initial diagnosis of 62y. In most cases, an early tumor (T1-T2) could be diagnosed, while 10 patients were diagnosed at an advanced tumor stage. 4 patients showed positive lymph node involvement of the neck at the initial diagnosis. Primary tumor resection was performed in 33 cases, with R0 resection not being achieved in 2 cases. Adjuvant radio-chemotherapy was performed in 19 cases. The average follow-up period at the current date is 34.5 months. During this period, 7 patients developed a local tumor recurrence that has been successfully treated by resection in all cases.

Finally, we use the case of an 82-year-old female patient with the diagnosis of T2,N0 SCC originating from the right nasal septum, to present our strategy in the sense of a two-stage surgical approach, which includes histographically controlled resection of the nasal cavity carcinoma, temporary defect coverage and subsequent multilayer reconstruction of the nose using nasolabial flap as well as cartilage from the cavum conchae, an approach which yields excellent results this far.
