Nose and Nasal Cavity

Nose and Nasal Cavity

The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Area of Science:

Otolaryngology
Head and Neck Surgery
Oncology

Background:

Sinonasal malignancy is rare, often presenting at advanced stages.
Effective management requires adherence to established guidelines.

Purpose of the Study:

To analyze presentation, diagnosis, and treatment outcomes of sinonasal malignancy.
To compare findings with the European Position Paper on Endoscopic Management.

Main Methods:

Retrospective audit of sinonasal malignancy patients over five years.
Review of clinical records and imaging data.

Main Results:

30 cases identified; nasal cavity and maxillary sinuses most common sites.
Squamous cell carcinoma (50%) and malignant melanoma (27%) were prevalent.
High incidence of late-stage (III/IV) presentation (70%); 30% mortality rate.
Endoscopic surgery utilized in only 20% of cases.

Conclusions:

Late-stage presentation significantly increases patient mortality.
High rates of malignant melanoma observed, with notable recurrence and survival challenges.
