Traditional open surgery is indicated for the treatment of selected tumor subsites in the head and neck. However, it can cause major cosmetic problems and functional pathologies. The endoscopically-assisted transoral approach is increasingly preferred in some surgical fields due to its superior cosmetic and functional outcomes. Nonetheless, endoscopically-assisted transoral approach is not yet standard in the head and neck due to their anatomical complexity. The transoral surgical approach has been used for head and neck masses since the 1960s, and its application continues to evolve with changing disease conditions and recent innovations in surgical instruments. The potential for wide application of transoral surgery continues to be investigated, with a focus on minimizing occurrence of the complications. This review presents details of the surgical procedure and postoperative clinical outcomes, as well as endoscopically-assisted scar-free techniques for the resection of midline neck masses.

Background and Objectives: There are various methods used to histologically assess the cell count of neutrophils in nasal polyps. With various classification of neutrophilic nasal polyps, determining the appropriate staining techniques and criteria is deemed important for the diagnosis of neutrophilic nasal polyps by assessing neutrophil cell counts. In this study, we tried to optimize different methods of neutrophil counting and staining by comparing clinical outcomes.Subjects and Method We studied 207 patients who underwent endoscopic sinus surgery for chronic rhinosinusitis with nasal polyp from August 2014 to September 2018. Patients’ nasal polyp were taken to make following three slide sections: hematoxylin and eosin, human neutrophil elastase (HNE), myeloperoxidase. After staining, microscope picture (×400) was taken and neutrophils were counted. Neutrophil polyp (NP) was classified either by the tissue neutrophil count (20/HPF) or by the neutrophil percentage (1%/total cell) for clinical outcome comparison. Results: Two groups were made after HNE staining: the NP and the non-NP groups. The L-K scores and delta showed significant differences between each group while neutrophil was defined based on 20 counts/HPF (p<0.001). By Kaplan-Meier estimation, there was no statistical meaning between the two groups. But the NP group had a tendency to recur more than the non-NP group while 20 counts/HPF definition was used (p>0.05). Conclusion HNE staining and 20 counts/HPF were the most specific for neutrophil counting. Analyzing the nasal polyp into two groups due to histologic types showed that the NP group had worse prognosis than the non-NP group. In conclusion, neutrophils in the nasal polyp might be considered seriously for clinical outcomes.

Maxillary sinus cancers, constituting a minority of head and neck malignancies, exhibit a diverse range of histological subtypes, each necessitating a nuanced approach to diagnosis and treatment. Within this spectrum, mucinous adenocarcinoma stands as an exceedingly rare variant, and this case report aims to provide a thorough examination of its clinical, radiological, and histopathological dimensions within the context of maxillary sinus malignancies. Surgical resection is considered as treatment of choice for this kind of tumor. A 68-year-old male underwent total maxillectomy using Weber-Ferguson incision for maxillary sinus tumor in our department. The pathological report of tumor was revealed as mucinous type adenocarcinoma. The specimen was observed thoroughly, and based on immunohistochemical findings, diagnosed as mucinous type adenocarcinoma. So, we present a rare case of mucinous type adenocarcinoma arising from the maxillary sinus.
