To compare mucosal and bony measurements in patients with congenital and traumatic nasal septum deviation and compensatory inferior turbinate hypertrophy.
The study examined 50 patients with nasal septum deviation (25 congenital and 25 traumatic) and compensatory inferior turbinate hypertrophy in the contralateral nasal cavity, confirmed by computed tomography.
The study compared inferior turbinate measurements on the concave and convex sides of the septum, in the congenital and traumatic groups. Measurements comprised: the shortest distance from the median line to the medial border of the conchal bone; the distances from the most medial part of the conchal mucosa and the conchal bone to the lateral line; the projection angle of the inferior turbinate; and the widest parts of the whole inferior turbinate and the inferior turbinate conchal bone. The differences between the concave and convex side measurements were compared in the congenital group versus the traumatic group; for three measurements, the difference between these two groups was statistically significant (p < 0.05).
The present study findings suggest that the conchal bone has a marked influence on nasal patency in patients with congenital septal deviation. These findings supported the decision to excise the inferior turbinate bone at the time of septoplasty, especially when treating congenital septal deviation.
In human beings, pain and taste perception are two major sensory inputs. We investigated whether increasing bitter taste sensitivity would increase intensity or incidence of pain associated with propofol, and whether there is a relationship between bitter sensitivity and venepuncture pain.
One hundred (50 males, 50 females) American Society of Anesthesiologists Grade I adults undergoing elective surgery were included in this study. Determination of the taste thresholds employed a series of propylthiouracil solutions. The filter paper disk method was used to measure the taste threshold. A 20-G intravenous (i.v.) cannula was inserted in the dorsum of the non-dominant hand. Venepuncture pain was assessed by using a numerical rating scale (NRS; 0, no pain and 10, extreme pain). Propofol 10 mL (100 mg) was injected over 30 s. Assessment of pain with i.v. propofol was made using a 4-point scale: 0, no pain; 1, mild pain; 2, moderate pain; 3, severe pain.
The NRS score of venepuncture pain was 2.8 ± 1.5. Sixty patients had pain during propofol injection. There was statistically significant correlation between bitter sensitivity and propofol injection pain, and between bitter sensitivity and venepuncture pain (P < 0.05).
We conclude that increased bitter taste sensitivity correlates with increased intensity or incidence of propofol injection pain and NRS of venepuncture pain.
