RESUMO

OBJECTIVE: Obtaining adequate hemostasis during otolaryngology operations is necessary because a small amount of blood can be problematic and obscure the visual field. The authors aimed to compare the efficacy of combined greater palatine canal (GPC) and transnasal injection of lidocaine + epinephrine to transnasal injection alone in patients who underwent septoplasty. METHODS: Patients with nasal septum deviation who were eligible for surgical correction of deviations were enrolled. Transnasal injections of 2 mL of 1% lidocaine + epinephrine 1:100,000 were performed in both groups and for patients in the combination group the same solution was also injected in the GPC. Objective (amount of suctioned blood) and subjective (intraoperative bleeding score) assessments were done during operation. Close hemodynamic monitoring was performed for all patients. RESULTS: A total of 50 patients were enrolled and randomly allocated to study groups. No significant differences were observed in systolic and diastolic blood pressure, heart rate, and mean arterial pressure of study subjects between 2 groups. The amount of bleeding in patients who received GPC injection and their counterparts in the other arm of the trial were 34.64 ±â€Š26.66 and 100.48 ±â€Š20.90 mL, respectively (P < 0.001). The mean intraoperative bleeding score in combination group was 0.79 ±â€Š0.42 and significantly lower than the corresponding figure in monotherapy group, which was 1.75 ±â€Š0.41 (P < 0.001). CONCLUSIONS: Based on the findings of the current study, the authors suggest that combined GPC and transnasal injection of lidocaine and epinephrine is a safe and effective method for reducing bleeding during septoplasty.

RESUMO

INTRODUCTION: In order to achieve a higher success rate for tympanoplasty, different techniques have been developed, and a wide variety of grafting materials have been developed. One of the techniques currently receiving considerable attention involves not lifting the remaining of eardrum from the malleus and embedding the graft underneath in order to repair the eardrum correctly in its original position, as well as minimizing graft lateralization leading to progression of hearing rehabilitation. We compared the effects of tympanoplasty with and without malleus lifting on hearing loss in patients with chronic otitis media. MATERIALS AND METHODS: In this study, 30 consecutive patients diagnosed as having chronic otitis media without cholesteatoma were randomly assigned to two tympanoplasty groups; with or without malleus lifting. Air and bone conduction thresholds were recorded before and 45 days after the intervention. RESULTS: In groups, except for 8000 Hz, the air conduction was significantly improved following surgery. According to air conduction there was no difference between the groups before surgery at different frequencies, although it was improved to a greater degree in the group without lifting at 250 Hz postoperatively. The average post-operative air-bone gap (ABG) gain was significantly higher in all study frequencies in the target group. One of the effects of this technique is inner-ear protection from physical trauma to the ossicular chain, and prevention of damage to bone conduction. CONCLUSION: A higher hearing threshold and also higher ABG gain can be achieved by not lifting the remaining eardrum from the malleus and embedding the graft undereath it, especially at lower frequencies.

RESUMO

In mastoid surgeries, contralateral ear noise exposure is a known, identified factor leading to high-frequency hearing loss due to the wide variety of surgical devices that may be used during the surgery. However, the hearing threshold recovery time after this trauma was uncertain. The present study aimed to assess this time. In this prospective survival analysis study, 28 consecutive patients with chronic otitis media who were undergoing tympanomastoidectomy were assessed. Standard pure-tone audiometry (PTA) and distortion-product otoacoustic emission (DPOAE) were measured in all contralateral ears before and 6 h, 24 h, 48 h, 72 h, and 96 h after the surgery. Based on the PTA postoperative hearing loss, survival rates at frequencies of 3000 Hz, 4000 Hz, 6000 Hz, and 8000 Hz were 44.4%, 36.4%, 51.7%, and 47.4%, 24 h after surgery; 11.1%, 9.1%, 10.3%, and 13.2%, 48 h after surgery; and 0%, 0%, 3.4%, and 2.6%, 72 h after surgery, respectively. Based on the PTA and DPOAE, survival rates at all frequencies were 0%, 96 h after the surgery. According to the PTA, mean hearing recovery times were 61.98 ± 26.76 h (3000 Hz), 62.73 ± 26.50 h (4000 Hz), 67.08 ± 25.90 h (6000 Hz), 70.70 ± 24.13 h (8000 Hz), and with regard to DPOAE the recovery times were 58.58 ± 28.39 h (2000 Hz), 63.32 ± 28.83 h (4000 Hz), 65.22 ± 29.13 h (6000 Hz), and 75.14 ± 22.70 h (8000 Hz), respectively. To conclude, high-frequency hearing loss usually occurs following mastoid surgeries that is mainly temporary and reversible after 72 h.
