The nasal cavity is the entrance to the respiratory tract. Its functions are to clean, warm, and humidify air as it is inhaled. Respiratory mucosa covered by pseudostratified ciliated epithelium and goblet cells, as described in Chapter 5 and illustrated in Figure 5.2B, lines the majority of the nasal cavity. The cilia and mucus trap particles, thus cleaning the air; the mucus also humidifies the air and warming is achieved through heat exchange from blood in the very vascular mucosa. The efficiency of all these processes is increased by expanding the surface of the nasal cavity by folds of bone. The nasal cavity also houses the olfactory mucosa for the special sense of olfaction although the olfactory mucosa occupies a very small proportion of the surface of the nasal cavity. The nasal cavity extends from the nostrils on the lower aspect of the external nose to the two posterior nasal apertures between the medial pterygoid plates where it is in continuation with the nasopharynx. Bear in mind that in dried or model skulls, the nasal cavity is smaller from front to back and the anterior nasal apertures seem extremely large because the cartilaginous skeleton of the external nose is lost during preparation of dried skulls. As you can see in Figure 27.1 , the nasal cavity extends vertically from the cribriform plate of the ethmoid at about the level of the orbital roof above to the palate, separating it from the oral cavity below. Figure 27.1 also shows that the nasal cavity is relatively narrow from side to side, especially in its upper part between the two orbits and widens where it sits between the right and left sides of the upper jaw below the orbits. The nasal cavity is completely divided into right and left compartments by the nasal septum . From the anterior view seen in Figure 27.1 , you can see that the surface area of lateral walls of the nasal cavity are extended by the three folds of bone, the nasal conchae. The skeleton of the external nose shown in Figure 27.2 comprises the nasal bones, the upper and lower nasal cartilages, the septal cartilage, and the cartilaginous part of the nasal septum.

Nose And Paranasal Sinuses

The external nose is pyramidal and consists of a bony cartilaginous framework. The root/radix is continuous with the forehead an inferiorly terminates at the nasal tip. The dorsum of the nose is formed by two lateral surfaces that converge in the midline. The cartilaginous structure of the nose is formed by paired upper (lateral) cartilages that contribute to the internal nasal valve with the nasal bones, and lower lateral cartilages, combined with additional minor nasal cartilages that surround the ala. The nasal septum relies upon anastomoses from five vessels: two from the ophthalmic, two from the maxillary and one from the facial. Collectively, they form Kieselbach’s plexus. The paranasal sinuses are the frontal, sphenoidal, ethmoidal and maxillary – located within the bones of the same name. They are paired structures lined with mucosa that is continuous with the lateral nasal side wall into which they drain, facilitating clearance of mucus by way of the mucociliary escalator.

Introduction. The primitive malignant melanoma of nasal mucosa and paranasal sinus is a rare tumor of uncertain etiology, with unpredictable biologic behavior and bad prognosis. Unlike skin melanomas, there are no risk factors and the disease is frequently manifested in older patients, whose clinical otorhinolaryngology complaints are normally non-specific and ranges from nasal obstruction to rhinorrhea and epistaxis. Unfortunately, this disease is diagnosed basically in advanced stages which makes the surgery difficult. Objective. To report a case of primitive malignant melanoma of nasal mucosa, ethmoid and frontal sinuses, that was diagnosed in 2015. It was performed a subtotal resection in another hospital in 24.08.2015, with a large local reccurence. Report. Our patient was a 78-year-old woman with bilateral nasal obstruction, light epistaxis and unilateral rhinorrhea. The ENT, CT and  MRI exams showed a tumour with important, invasion of the nasal cavity structures (billateral nasal bones, left frontal process of the maxilla, the superior midpoint of the nasal septum, bilateral middle and superior turbinates, left ethmoid and bilateral frontal sinuses). The patient was submited for surgery: total macroscopic resection in the combined endoscopic approach; transnasal and modified lateral rhinotomy with titaniul plates reconstruction of the external nose architecture. Conclusions. Malignant melanomas of nasal mucosa are, in general, diagnosed in advanced stages. Their histological characteristics in the mucosa makes difficult the surgical treatment, which is one of the most efficient options, because they are resistant to chemo and radiotherapy. The early diagnosis and a good surgical treatment plan are the best option for this tumor nowadays.

Abstract Background: This study investigates and compare the reliability and reproducibility of two facial anthropometric methods about external nasal angles, 3D imaging and conventional 2D photography. Methods: 2D photograph images and 3D images about external nose of 30 volunteers were taken using digital camera and Morpheus 3D scanner. To evaluate intra-rater reliability, each images were taken over two different days for each subject by the same researcher. To evaluate inter-rater reliability, another researcher took each images for each subject on the first day. The reliability of each method for measuring 4 external nasal angle is obtained using intraclass correlation coefficient (ICC) and compared.Results: Inter-rater and intra-rater reliability of both 3D imaging and 2D photography had excellent agreement in all 4 nasal angles. In the nasofacial angular parameter, Inter-rater ICC, 2D photography was significantly higher than 3D imaging. Result of intra-rater ICC also showed both 3D imaging and 2D photography had good reliability in all 4 nasal angles. Similar to those of inter-rater ICC, nasofacial angular parameter showed statistically significant differences between 3D imaging and 2D photography.Conclusion: In terms of reliability, both 2D and 3D showed appropriate anthropometric results and considering its own advantage, each methods can be used complementarily.

Numerous injuries (and their treatment) have been encountered since the very beginning of the development of human civilization and remain one of the most significant problems in our time, since the frequency of injuries in general (and of ENT organs in particular) does not tend to decrease either in children or adults. ENT injuries are in fourth place in terms of emergency appeal rates. The most common injury to the maxillofacial area is a fracture of the skeleton of the nose. The article presents data on the frequency of occurrence of this pathology and describes the features of the causes that caused it in different periods of childhood, presents an algorithm for managing patients. The role of homeopathic arnica-containing remedies (Arnigel®) in the conservative treatment of reactive post-traumatic events from the soft tissues of the external nose is shown.

<p class="abstract"><strong>Background:</strong> Deviated nasal septum (DNS) is one of the most frequent causes of nasal obstruction in adults. An anterior rhinoscopy (AR), which is usually the first diagnostic procedure in the evaluation of obstructive nasal pathologies, is often inadequate in the assessment of the posterior nasal cavity and the gold standard method for the evaluation of paranasal anatomy and inflammatory paranasal sinus pathologies is paranasal sinus computed tomography (PNS CT). Aim was to validate the recommendation of pre-operative computed tomography scan in minimizing post-septoplasty complications.</p><p class="abstract"><strong>Methods:</strong> A retrospective record based study was conducted including all patients with clinically diagnosed DNS and undergone surgical intervention at Khamis Mushayet General Hospital. Data extracted included patients demographic data, and post-operative recorded complications and history of preoperative CT scan for evaluating and grading DNS.  </p><p class="abstract"><strong>Results:</strong> A total sample of 60 patients’ undergone septoplasty for DNS. Patients who undergone preoperative CT were 30. The remaining 30 patients didn’t undergone pre-operative CT for evaluation of DNS. The most diagnosed complication was nasal obstruction (28.3%) followed by external nose deformity (20%). Exact of 47% of patients had postoperative nasal obstruction didn’t undergone pre-operative CT. About 42% of those who had postoperative nasal deformity didn’t undergone CT while 33% of patient who had post-operative bleeding and septal perforation didn’t undergone CT.</p><p class="abstract"><strong>Conclusions:</strong> In conclusion, the study revealed that preoperative CT showed insignificant efficacy in relieving nasal obstruction or minimizing postoperative complications.</p>
