METHODS: A prospective randomized comparative trial was conducted among patients with bilateral nasal blockage secondary to inferior turbinates hypertrophy. Patients were randomly assigned to MAT or CAT. An extraturbinal medial flap turbinoplasty was performed for both techniques. Symptom assessment was based on the visual analogue score for nasal obstruction, sneezing, rhinorrhea, headache and hyposmia. Turbinate size, edema and secretions were assessed by nasoendoscopic examination. The assessments were done preoperatively, at 1st postoperative week, 2nd and 3rd postoperative months. Postoperative morbidity like pain, bleeding, crusting and synechiae were documented. The clinical outcomes of both techniques were analyzed using repeated measures ANOVA.
RESULTS: A total of 33 participants were recruited, 17 patients randomized for MAT and 16 patients for CAT. Nasal obstruction, discharge, sneezing, headache and hyposmia significantly reduced from 1st week until 3 months for both procedures. Similar significant reductions were seen for turbinate size, edema and secretions. However, there was no significant difference in symptoms and turbinate size reduction were seen between both groups at the first postoperative week, 2nd and 3rd postoperative months. There was significant longer operating time for CAT when compared to MAT (p = 0.001). The postoperative complications of bleeding, crusting and synechiae did not occur in both groups.
CONCLUSION: Both MAT and CAT were equally effective in improving nasal symptoms and achieving turbinate size reduction in patients with inferior turbinate hypertrophy. Both MAT and CAT offer maximal relieve in patients experiencing inferior turbinates hypertrophy by removing the hypertrophied soft tissue together with the turbinate bone without any complications.
METHODOLOGY: A retrospective chart review on computed tomography paranasal sinus (CTPNS) was conducted. A total of 200 patients who had clinical and endoscopic findings of chronic rhinosinusitis (CRS) and undergone CTPNS were reviewed. The CTPNS was evaluated for the presence of frontal cell variants according to IFAC and mucosal changes consistent with frontal sinus involvement.
RESULT: A total of 400 sides of the CTPNS were analyzed. The agger nasi cells (ANCs) were the most common (95.5%) followed by supra bulla cells (SBCs) (60.8%), supra bulla frontal cells (SBFCs) (53.0%), supra agger cells (SACs) (50.0%), supra agger frontal cells (SAFCs) (36.0%), frontal septal cells (FSCs) (8.3%), and supraorbital ethmoidal cells SOECs (5.5%). There was significant association between SOEC (p = 0.001) and FSC (p = 0.044) with the development of frontal sinusitis.
CONCLUSIONS: Apart from ANCs, the posterior-based cells (SBCs and SBFCs) have higher prevalence than the anterior-based cells (SACs and SAFCs). Despite being the least, both SOECs and FSCs are significantly associated with frontal sinusitis.
METHODS: An electronic search was performed via PubMed, SCOPUS, Google Scholar, and Cochrane from inception to June 2022. The included trials were evaluated according to the recommendations of the Cochrane Handbook for Systematic Reviews. The primary outcome assessed was the intraoperative bleeding score of the surgical field. The mean arterial pressure, duration of the surgery, amount of blood loss and surgeon's satisfaction score were assessed as the secondary outcomes. The risk of bias for each study was evaluated using the Cochrane risk of bias tool.
RESULTS: A total of 254 records were identified after removal of duplicates. Based on the title and abstract 246 records were excluded, leaving seven full texts for further consideration. Five records were excluded following full text assessment. Three trials with a total of 212 patients were selected. Hot saline irrigation was superior to control in the intraoperative bleeding score (MD - 0.51, 95% CI - 0.84 to - 0.18; P < 0.001; I2 = 72%; very low quality of evidence) and surgeon's satisfaction score (RR 0.18, 95% CI 0.09 to 0.33; P < 0.001; I2 = 0%; low quality of evidence). The duration of surgery was lengthier in control when compared to HSI (MD - 9.02, 95% CI - 11.76 to - 6.28; P < 0.001; I2 = 0; very low quality of evidence). The volume of blood loss was greater in control than HSI (MD - 56.4, 95% CI - 57.30 to - 55.51; P < 0.001; I2 = 0%; low quality of evidence). No significant difference between the two groups for the mean arterial pressure was noted (MD - 0.60, 95% CI - 2.17 to 0.97; P = 0.45; I2 = 0%; low quality of evidence).
CONCLUSIONS: The practice of intranasal HSI during ESS is favorable in controlling intraoperative bleeding and improving the surgical field quality. It increases the surgeon's satisfaction, reduces blood loss, shortens operative time and has no effect on intraoperative hemodynamic instability.
TRIAL REGISTRATION: PROSPERO registration number: CRD42019117083.
METHODS: This is a double-blind randomized clinical trial, involving 26 patients with CRSwNP, who underwent FESS for failed medical therapy. The intervention nostril was packed with ribbon gauze soaked in 500 mg/5 ml TXA. The control nostril was packed with ribbon gauze soaked in Moffett's solution, containing 2 ml 10% cocaine, 1 ml adrenaline 1:1000, and 4 ml 0.9% sodium bicarbonate. Both nostrils were packed for 15 min before FESS. Intraoperative bleeding was recorded in the initial 30 min after commencing the surgery. The recordings were reviewed by two surgeons using Boezaart's scoring system. The scores were taken at 15 and 30 min of surgery. The mean score was then calculated. At the end of the surgery, the intervention nostril was packed with Merocel® soaked in 500 mg/5 ml TXA and the control nostril was packed with Merocel® soaked in normal saline. The amount of bleeding within 24 h post-surgery was evaluated using a bolster gauze.
RESULTS: There was no significant difference in intraoperative bleeding between the intervention (1.54 ± 0.71) and control nostrils (1.69 ± 0.55) with p = 0.172. The amount of bleeding in the postoperative period was significantly reduced in the intervention nostril (1.33 ± 0.55) compared to the control nostril saline (1.81 ± 0.48) with p = 0.001.
CONCLUSIONS: We found that the nasal packing soaked in TXA reduced intraoperative and immediate postoperative bleeding. It is a safe, efficacious and cost-effective alternative to Moffett's solution during FESS and also an alternative to normal saline post-surgery among patients with CRSwNP.
TRIAL REGISTRATION NUMBER: FF-2015-232, 2015.
MATERIAL AND METHODS: A prospective, quasi-experimental physiological study. Selected healthy subjects were observed electrocardiographically for 60 s continuously in three equal phases of 20 s each - baseline phase, nasoendoscopic phase, and recovery phase (post-nasoendoscopy). Heart rate fluctuations were charted, followed by identification of a positive nasocardiac reflex group of subjects and a negative group. Analyses against multiple variables were done.
RESULTS: A total of 53 subjects were analysed. Heart rate during the baseline phase was 81.0 ± 9.9, nasoendoscopic phase was 72.7 ± 10.1, and recovery phase was 75.2 ± 9.6. Sixteen subjects (30.2%) had a positive nasocardiac reflex, and they remained in sinus rhythm with no occurrences of skipped beats, atrioventricular blocks or asystoles. One subject (1.9%) developed temporary ectopic premature ventricular contractions after nasoendoscopy. No variables were found affecting the incidence of a nasocardiac reflex in our study.
CONCLUSIONS: The pattern of heart rate dynamics was consistent as heart rates drop rapidly upon endoscope insertion and recover in some measure after its withdrawal. Although all our subjects remained asymptomatic, clinicians should not overlook the risks of a severe nasocardiac reflex when performing nasoendoscopy. We recommend that electrical cardiac monitoring be part of the management of vasovagal responses during in-office endonasal procedures.
