Bone can be categorised into four types which are long, short, flat and irregular bone. Long bone such as femur, tibia, humerus, radius and ulna can be found in the limbs. Short bones are carpal and tarsal. Flat bone are ribs, sternum, cranium and scapula. Irregular bones are vertebrae, sacrum, coccyx, temporal, mandible, palatine, inferior nasal concha, hyoid, sphenoid, ethmoid, zygomatic, and maxilla (Buckwalter et al. 1995) and lastly, sesamoid that is patella and smaller bones found in flexor hallucis longus and peroneus longus tendons (Buckwalter et al. 1995).

This section traverses the nasal septum (1) at the level of the inferior nasal concha (3), beneath which opens the nasolacrimal duct (4). This is the only structure that drains into the inferior meatus of the nasal cavity. Its termination is guarded by a mucosal valve, which prevents reflux from the nose.

Nasal cavity - on either side of the nasal septum (Fig.3.24), the roof of each half is only 1-2 mm wide, although the floor (the upper surface of the hard palate) is more than 1 cm wide. The lateral wall is the most complicated feature; its skeleton is made up of parts of the maxilla, the palatine and ethmoid bones and the inferior nasal concha (the superior and middle nasal conchae are part of the ethmoid bone).

Nonetheless microsmia and anosmia occur after the MET approach. This may be accounted for by surgical trauma to the superior nasal septum when using the speculum, with involvement of the fila olfactoria. Mucosal lacerations heal with synechias – scarring of the mucosal tissue, an event that appears to interfere with post-operative QoL following endonasal surgery.27 Kahilogullari et al. observed that synechias are more frequent in the microscopic group as compared with the endoscopic group (respectively 36% and 9%). These are most likely due to the endonasal introduction of surgical instruments and their presence is significantly related to olfactory disturbances.13 Endoscopic-related synechias tend to occur more in the anterior portion of the inferior nasal concha, while the microscopic-related synechias are more postero-superior, in proximity to the olfactory cleft. The opening of the speculum blades in the anterior walls of the sphenoid sinus applies a significant force on the olfactory groove, with potentially limited control, as only the medial side of the blade can be seen, and the submucosal layers may be lacerated bilaterally.13
The effect of premature ovarian insufficiency on nasal mucociliary clearance time
Published in Gynecological Endocrinology, 2020
The saccharin test is an easy, low-cost and painless clinical test for defining nasal mucociliary clearance time [11]. The patients did not to eat or drink anything for 1 h before the test. Then, 1/4 of a saccharin tablet is placed on the surface of the inferior nasal concha. The patients must breathe normally without sneezing or blowing their noses during the test. The saccharine particle is carried by means of ciliary transport along the entire nostril until it reaches the oropharynx, consequently a characteristic sweet taste can be perceived. The time was recorded to the minute (min) and the test was considered complete [12].

A 71-year-old man who had right eye swelling was found to have a tumor arising from the right lacrimal sac that had spread to the inferior nasal concha (Figure 1a). Biopsy revealed squamous cell carcinoma. Magnetic resonance imaging (MRI) showed a tumor originating from the lacrimal sac and invading the inferior nose (Figure 1b) and positron emission tomography-computed tomography (PET-CT) as well as metastases to the neck nodes bilaterally and to the contralateral retropharyngeal node (Figure 1c). The diagnosis revealed lacrimal sac squamous cell carcinoma, T4cN1M0 according to the Cancer.Net classification.
