Inferior Turbinate Hypertrophy

A pilot study to assess the safety and efficacy of ’degloving’ of the inferior turbinate is described. This prospective study reports on the effectiveness of the technique in 37 patients with nasal obstruction due to inferior turbinate hypertrophy. Both objective and subjective measurements of nasal patency were made pre-operatively, and repeated at six weeks, six months and two years post-operatively using nasal inspiratory peak flow rates, saccharin clearance time and an end referenced visual analogue scale to record nasal symptoms.There was a significant improvement in the peak inspiratory flow at six weeks (96.4 to 151.2 l/min) and at six months (148.4 l/min), which was sustained at two years (117.1 l/min, p<0.001). There was an overall improvement in patient satisfaction with nasal symptoms (23.4 to 76.7, 76.8 and 66.8 at six weeks, six months and two years, p<0.001) and a decrease in the sensation of nasal obstruction (71.9 to 21.5, 32.9 and 29.8, p<0.001), which was also sustained. Rhinorrhoea was reduced, and sense of smell increased across the group, but the improvements did not reach statistical significance. The results for postnasal drip and saccharin clearance did not show a significant change over the period of the study. There were no haemorrhagic complications in the group studied.This pilot study demonstrates a new surgical technique for reduction of the inferior turbinates, that yields significant improvement in nasal obstruction, an acceptably low complication rate and is well tolerated by patients. A randomized controlled trial is being planned.

This pilot study aims to compare cardiorespiratory parameters in female dogs that underwent either laparoscopic or open elective gonadectomy with spontaneous ventilation anaesthesia. Records of 77 client-owned female dogs were reviewed. Patients were divided into two groups: laparoscopic surgery (L group, n 47) and open abdominal surgery (O group, n 30). The end-tidal carbon dioxide, respiratory rate, oxygen saturation, heart rate, non-invasive arterial blood pressure and length of procedure were recorded and statistically evaluated. Once normality of the sample data has been assessed, equality between the groups was analysed with two-sample Student’s or Welch’s t-test, whether the hypothesis of variance equality, through an F-test, was verified or not. A value of p <0.05 was considered statistically significant. No statistically significant difference was found between groups regarding the end-tidal carbon dioxide, oxygen saturation, respiratory rate, heart rate, systolic and medium arterial pressure values. Mean diastolic pressure was lower in the L group. The procedure length between the two groups was statistically different: laparoscopy was shorter than open surgery. In spontaneously ventilating female dogs, the cardiorespiratory parameters evaluated seem not to be affected by the presence of pneumoperitoneum when intrabdominal pressure is kept between 8 and 10 mmHg. The pilot nature of the study and the shorter laparoscopic surgery length could bias these results. However, in the author’s opinion, these findings confirm the interest of laparoscopy and the small impact of this mini-invasive technique in healthy patients.
