The maxillary sinus continues to grow until age 18 then it stops. Another expansion is
observed when a maxillary molar tooth is extracted in the process known as expansion.
B 2. The opening of the maxillary sinus is located in a dependent position. The maxillary sinus is
the biggest among all paranasal sinuses.
True all
The opening of the maxillary sinus is located in a dependent position. The maxillary sinus is
the biggest among all paranasal sinuses.
1st statement is false, 2nd statement is true 1st statement is false, 2nd statement is true
Intrusion of a non infected tooth in the maxillary sinus is acceptable to be left behind in the area regardless of the size. Any intruded foreign body in the maxillary sinus will be stabilized in a particular area so it will not be moving all over the entire sinus area.
Both sentences are false
The height of the maxillary sinus is more than its anteroposterior length. The base of the
maxillary sinus is at the zygomatic arch.
Both sentences are false
Oro-antral communication should be avoided at all cost. This can lead to chronic sinusitis
Both sentences are true
The most usual cause of sinusitis from dental infection is of the gram positive aerobic
bacterial species.
F
n closing a long-standing oro-antral communication, the gingival tissue surrounding the
opening should be incised. This is to break the continuity of the oral mucosa from the
Schneiderian membrane to create a separation of the maxillary sinus from the oral cavity for independent healing
C
The best view for the maxillary sinus is the panoramic x-ray.
F
If a molar tooth is accidentally intruded into the maxillary sinus, the communication should
be enlarged to be able to remove the tooth from the socket. The socket could just be
compressed and sutured with a figure of eight suture on top of the socket to manage oro-antral
communication.
Both sentences are false
Transillumination of the maxillary sinus is one way to check if the sinus is infected or not.
A person with sinusitis will have a through and through passage of light from the cheek to the
palate or vice versa
1st statement is true, 2nd statement is false
In retrieving an intruded tooth or tooth part from the maxillary sinus, the operator can
insert the instrument inside the sinus in search for the displaced tooth part. To properly expel the
mucus content of the sinus, it has to rely to the action of the cilia that is present in the epithelium of the sinus.
1st statement is false, 2nd statement is true
The maxillary sinus is lined with stratified columnar epithelium. The epithelium of the sinus
is the same as that of the oral cavity.
Both sentences are false
Berger’s technique is synonymous with the pedicle flap. The Berger’s flap is reflected on

Both sentences are false
One of the important things to consider in perforated sinus is to advise the patient not to
suck on straw and sneeze that directs all the force towards the nose and the ears.
True
Patient is advised not to blow on his nose during the healing time for the sinus membrane
to heal and create a separate environment from the oral cavity. To avoid the patient from
blowing his nose relentiessly, the patient is prescribed with nasal decongestant and
antihistamine that lasts for 2 weeks to make the maxillary sinus and the nose dry from any
discharges.
