Introduction:

ANATOMY OF THE NOSE AND PARANASAL SINUSES

 

Nasal cavity

     The nasal cavity extends from the external nares or nostrils to the posterior choanae, where it becomes continuous with the nasopharynx. Vertically, it extends from the palate to the cribiform plate, being broader at its base than superiorly where it narrows to the olfactory cleft. The nasal cavity is divided into two by a septum. Each half has a floor, a roof, a lateral wall and a medial (septal) wall.¹

     The floor  is composed of  the palatine process of the maxilla in its anterior three-quarters from side to side and its posterior one-quarter by the horizontal process of the palatine bone. 

     The roof is narrow from side to side, except posteriorly, and  may be divided into frontonasal, ethmoidal and sphenoidal parts.

     The inner surfaces of the maxillae, the lacrimal bones, the superior and middle turbinates, the inferior turbinate, and the medial pterygoid make up the lateral wall. The three scroll-like, pitted turbinate bones, or the conchae, on each side of the nose divide the nasal lumen into meati. The space between the inferior turbinate and floor of the nose is the inferior meatus, the space between the inferior and middle turbinates is the middle meatus, and the space above the middle turbinate is the superior meatus. Occasionally, there is a supreme turbinate. The middle and superior turbinates are extensions of the ethmoid bones, whereas the inferior turbinate is a separate bone attached by its superior border to the lateral nasal wall.¹

 

 F igure 1.1  : Anatomy of the nasal cavity²

  Nasal septum 

  The nasal septum is composed of a small anterior membranous portion, cartilage and several bones: the perpendicular plate of the ethmoid, the vomer and  two bony crests of the maxilla and palatine The cartilaginous portion is composed of a quadrilateral

cartilage with a contribution from the lower and upper lateral alar cartilages forming the anterior nasal septum ¹ .

 

Figure 1.2 : ANATOMY of The nasal septum¹

Anatomy of the ostiomeatal unit

 The term “ostiomeatal unit” describes the area on the lateral nasal wall where the ostia of the paranasal sinuses (except for the sphenoid sinus) open into the nasal cavity in a duct-like fashion. The functionally significant anatomic structures of the ostiomeatal unit are the uncinate process, the semilunar hiatus, the frontal recess, the ethmoid bulla, the ethmoid infundibulum, and the maxillary sinus ostium

  The frontal sinus is connected to the ostiomeatal unit via the frontal recess, which has an hourglass-like shape. The uncinate process is a thin fibrous or bony process on the lateral nasal wall that arises slightly behind the anterior border of the middle turbinate. Located between the posterior border of the uncinate process and the first ethmoid cell (the ethmoid bulla) is another slit like passage within the ostiomeatal complex, known as the semilunar hiatus. The space between the uncinate process, ethmoid bulla, and lamina papyracea of the ethmoid bone is called the ethmoid infundibulum. The ostiomeatal unit is bounded medially (toward the nasal cavity) by the middle turbinate and laterally by the lamina papyracea⁴

 

 

Figure 1.3 : Anatomy of Paranasal sinuses⁵

Paranasal sinuses

Ethmoidal Sinus

  The ethmoid sinuses are the central structures of the nose with complex anatomy; they are best visualized as a box-like structure with open anterior and inferior faces. The lateral portions form the medial walls of the orbits, the sphenoid establishes the posterior face, the superior surface is formed by the skull base of the anterior cranial fossa, and many of the key structures of the lateral nasal wall, derived from basal lamellas, extend posteroinferiorly from the skull base⁴.

  The lateral wall of the ethmoid sinus or lamina papyracea forms the paper-thin medial wall of the orbit. The midline vertical plate of the ethmoid bone is composed of a superior portion in the anterior cranial fossa called the crista galli and an inferior portion in the nasal cavity called the perpendicular plate of the ethmoid bone that contributes to the nasal septum. The anterior cranial fossa is separated from the ethmoid air cells superiorly by the horizontal plate of the ethmoid bone, which is composed of the thin medial cribriform plate and the thicker, more lateral ethmoid roof. The ethmoid roof articulates with the cribriform plate at the lateral lamella of the cribriform plate, which is the thinnest bone in the entire skull base. ⁵

Maxillary Sinus

     The maxillary sinus is the pneumatized space within the maxillary bone and is the largest of the paranasal sinuses. The anterior wall forms the facial surface of the maxilla, the posterior wall borders the pterygopalatine fossa, the medial wall constitutes the lateral wall of the nasal cavity, the floor of the sinus is the alveolar process, and the superior wall serves as the orbital floor

     The natural ostium of the maxillary sinus opens into the superior aspect of the medial wall to drain into the ethmoidal infundibulum. Accessory maxillary sinus ostia are found in 15% to 40% of subjects, most commonly superior and posterior to the uncinate process above the insertion of the inferior turbinate.⁵

Frontal Sinus

     The size of the frontal sinus varies depending on the degree of pneumatization, may be completely absent (5%), and is usually divided by an intersinus septum. The frontal sinus lies within the frontal bone between thick anterior table and a relatively thin posterior table, separating the sinus from the frontal lobe of the brain. The floor of the frontal sinus corresponds to the anterior roof of the orbit. The frontal sinus drainage pathway has an hourglass shape and opens in the nose at the level of frontal recess. The narrowest point of this tract is called the frontal infundibulum of ostium and located at the most inferomedial aspect of the sinus.⁵

Sphenoid Sinus

     The sphenoid sinus has many important neurovascular relationships. The internal carotid artery is lateral to the sphenoid sinus as it courses through the cavernous sinus producing a prominence in the lateral sphenoid sinus wall. An optic nerve prominence is present in 40% of individuals with dehiscence in 6 %.

     The sinus cavities are variable in size and shape. Pneumatization can extend into the greater wing, pterygoid processes and rostrum. Four general forms of pneumatization are described:

1. Conchal pneumatization, with only a rudimentary sinus (2-3%).

2. Presellar, in which the sinus is pneumatized as far as the anterior bony wall of the pituitary fossa (11%).

3. Sellar, in which pneumatization extends back beneath the pituitary fossa (59%).

4. Mixed (27%)

The sphenoid sinus ostium opens into the sphenoethmoidal recess. ⁴

The turbinates

     These are usually three ( rarely four), and they appear as delicate shelf like bony structures protruding from the lateral nasal wall covered by ciliated columnar mucous epithelium. The superior, middle, and inferior turbinates are present in almost all individuals, and a very small supreme turbinate may also occur. The supreme, superior, and middle turbinates are included in the ethmoid bone. The inferior turbinate is a separate bone.¹

The superior turbinate

     It measures about 1.5 cm in length and is attached to the lamina papyracea of the ethmoid bone by a thin bony partition. The superior meatus contains the ostia of the posterior ethmoidal cell. A small ridge; the superme turbinate is sometime visible above the superior turbinate.⁴

The middle turbinate

     Is about 4 centimeter in length. The anterior end of the middle turbinate inserts into the ascending process (the ethmoid crest) of the maxilla and the posteromedial edge of the agger nasi. The superior attachment is in the paramedian sagittal plane and adheres to the lateral edge of the perforated portion of the cribriform plate along the ethmoid roof to a more vertical orientation along the lamina papyracea of the ethmoid bone. This twisting attachment of the middle turbinate bends within the middle third of the basal lamella, resulting in a prominent anterior vertical portion and a posterior descending horizontal plate. The posterior portion of the insertion of the middle turbinate runs in a horizontal plane forming the roof of the posterior middle meatus.⁴

     This posterior end is attached to the ethmoid crest of the perpendicular plate of the palatine bone. Pneumatization of the middle turbinate is frequent at its anterior end and in the main body mass. The middle meatus lies between the middle and inferior turbinate attachments. The lateral wall of the middle meatus is the most important area of the lateral wall of the nasal cavity, as many of the paranasal sinuses open here ⁴

Inferior Turbinate

     The inferior turbinate is an independent anatomical structure. The bone is scroll shaped and attached to the conchal ridge of the medial process of the maxilla and the palatine bone. It also articulates with the lacrimal bone by its lacrimal process and covers the lacrimal groove to form the bony canal for the nasolacrimal duct. The inferior meatus lies inferolateral to the inferior turbinate. The nasolacrimal duct is the only structure that opens in this meatus⁴

 MUCOCILIARY PHYSIOLOGY

     The mucosal lining of the paranasal sinuses is made up of a ciliated cuboidal epithelium. The mucous blanket of sinonasal cavities is composed of two layers: the gel and sol phases.The gel phase, or the superficial layer, is produced by goblet and submucosal glands and provides an environment that traps foreign particulate matter, which can then be cleared through the mucociliary clearance actions of the cilia. The sol phase, or the deep layer, is produced by microvilli and provides a fluid that facilitates ciliary motility as well as movement of the gel layer. The mucous blanket consists of mucoglycoproteins, immunoglobulins, interferon, inflammatory cells, and a variety of other immunologic substances⁶

     Cilia move mucus at a rate of 3 to 25 mm/min toward natural sinus ostia and ultimately to the nasopharynx and oropharynx where the transported mucus is swallowed.⁵

Nasal septal deviation

Nasal septal deviation or deviated nasal septum is physical  disorder of the nose ,involving displacement of nasal septum. some displacement is common ,affecting 80% of people ,most unknowingly.¹⁰

Sever septal deviation cause symptoms  of difficulty breathing and require treatment. Symptoms of deviated nasal septum include infection of the sinuses ,snoring and sleep apnea , ,facial pain ,nosebleeds, mild to sever lose ability to smell. 

The nasal septum is the bone and cartilage in the nose that that separate the nasal cavity into the two nostrils.the cartilage is called the quadrilateral cartilage and the bones comprising the septum include the maxillary crest ,vomer,and the perpendicular plate of ethmoid .Normaly ,the septum lies centrally and thus the nasal passages are symmetrical .adeviated septum is an abnormal condition in which the top the top of cartilaginous ridge leans to the left or to the right ,causing obstruction of the affected nasal passage.The condition can result in  poor drainage .people can also complain of difficulty breathing ,headache, bloody nose, sleeping disorder as snoring.

It’s common for nasal septa to depart from the exact centerline;the septum only consider deviated if the shift is substantial or causes problems.many people with adeviation are unaware they have it until some pain is produced. By itself ,adeviated septum can go undetected for years and thus be without any need for correction   ,and can classify degree of deviation in to :(mild simple deflection , moderate  cross deflection  but not touch the lat wall ,sever  deflection obstructed touch the lat wall).

The most frequently caused by impacted trauma ,such as by a blow to the face ,it can also be congenital disorder

The best initiated by nasal symptoms noting duration periodicity, nocturnal variation , associated trauma and previous surgery

The enquiry should cover the presence of nasal obstruction or congestion ,facial pain,hyposmia,rhinorhoea,post nasal drip and secondary symptoms sneezing,itching,dry mouth

Understanding the symptoms and their association is not useful diagnostically but also create of level of quality life impairment suffered⁷.  

 

Examination

Examination of the nose:

- Examine the nose externally from the front and side views, looking at the skin type and thickness, scars and lesion

- Tilt the head of the patient backwards to examine the columella and the vestibule.

- Check the patency of the nasal airway on each side with a metallic tongue depressor or by occluding the nostril with the thumb and asking the patient to sniff through the nose.

- Inspect nasal cavities using killian nasal  speculum and assess the nasal septum for deviation, perforation, vessels, mucosal lesions, inferior turbinates (hypertrophy, mucosal changes), nasal masses (polyps, lesions).

- Perform a rigid naso-endoscopy  after application of decogestant (often combined  with local anasthesia )to inspect the nasal cavity and post-nasal space⁷

Rigid naso-endoscopy:

This is regarded as the standard technique for assessing the nose. It may be performed with the patient seated or laying supine on an examination couch.

- Use a 4mm 0° and 30° endoscope. A 2.7mm scope can be helpful in a narrow nose.

- Use the standard three-pass technique.

   Flexible  Nasopharyngeal fibrotic endoscopy .

 

COMPUTED TOMOGRAPHY

CT is the current imaging standard for the evaluation of sinuses diseases because of its exquisite ability to display and differentiate hypertrophic mucosa, bone, and air.

It has poor soft tissue contrast and should not be relied upon for assessment of soft tissues. Iodinated contrast administration is unnecessary for evaluation of rhinosinusitis and should be reserved to assess neoplastic diseases and complications of acute sinusitis in select cases.⁸

Discussion:

   There are three theories explaining physiopathological relation between The nasal septal deviation and chronic rhinosinusitis. The first of these is the mechanical theory which states that secretions accumulates in the sinus as a result of narrowing of the ostiomeatal complex and thus infections ensues in the retained secretions and causes chronic rhinosinusitis. The second theory is the aerodynamic theory. According to this theory, the mucociliary activity decreases following the nasal flow rate increase and mucosal dryness in relation with the nasal septal deviation and consequently, chronic rhinosinusitis develops. The third theory is the Bachert’s pressure theory. According to this theory, deviation of the posterior nasal septum causes chronic rhinosinusitis by creating pressure and air flow changes within the maxillary sinuses ⁽¹²⁾
