The effect of continuous positive airway pressure on middle ear pressure.

OBJECTIVES/HYPOTHESIS: To investigate the effect of continuous positive airway pressure (CPAP) on middle ear pressure in patients with obstructive sleep apnea syndrome (OSAS). STUDY DESIGN: Prospective clinical case-control study. METHODS: Seventy-eight patients with moderate and severe OSAS (the mean apnea-hypopnea indexes were 22.70 ± 3.59 and 48.59 ± 12.50, respectively) using CPAP (study group) and 60 patients with no sleep apnea syndrome (control group) were included in the study. Forty-two of the patients were female and 96 were male. The mean age in the study group was 47.38 ± 6.23, whereas it was 46.10 ± 11.96 in the control group (P > .05). The middle ear pressure of all study subjects was evaluated with tympanometry at the beginning of the study and 6 months later. Tympanometric measurements of both groups were compared. Furthermore, the same data for the study group were also evaluated according to CPAP pressure levels. RESULTS: The middle ear peak pressure values of the patients in the study group were significantly increased from -63.04 ± 55.82 daPa to -39.6 ± 27.72 daPa after 6 months (P < .01). The middle ear pressure in the control group was found to be -13.26 ± 22.60 daPa at the beginning of the study and -13.60 ± 38.82 daPa after 6 months (P > .05). The mean middle ear pressure level was significantly higher in patients using CPAP at 12 to 14 cm H2 O pressure than in those using CPAP at 8 to 10 cm H2 O pressure (P < .05). CONCLUSIONS: There was a significant increase in the middle ear pressure of patients using CPAP regularly for 6 months. This increase was proportional to the pressure level of the CPAP device. LEVEL OF EVIDENCE: 3b.

Modified tongue base suspension for multilevel or single level obstructions in sleep apnea: clinical and radiologic results.

OBJECTIVES: To investigate the radiologic and polysomnographic success in opening the airway using a tongue base suspension procedure alone or in combination with uvulopalatal flap in obstructive sleep apnea syndrome (OSAS) patients. METHODS: This study was conducted in 20 patients with moderate or severe OSAS in a prospective manner. The tongue base suspension technique alone or with a uvulopalatal flap (UPF) technique was applied. Magnetic resonance imaging (MRI) scans of patients obtained during the preoperative period and at the 5th week of the postoperative period were compared. Changes in pain and swallowing difficulties were assessed. Polysomnography (PSG) was applied at the 12th postoperative month, and body mass index (BMI) and Epworth sleepiness scale (ESS) values were determined. The degree of satisfaction relative to the surgery was assessed with 4 questions. RESULTS: Preoperative apnea-hypopnea index (AHI) level was found to be 24.55±9.87, whereas postoperative AHI level was 12.40±9.87 (P<0.01). The success rate was determined to be 60%. Preoperative ESS values were 13.90±2.67 and were reduced to 6.55±3.13 postoperatively (P<0.01), and the preoperative posterior airway space (PAS) level was 10.08±1.23, which was increased to 11.64±1.46 postoperatively (P<0.01). Visual analog scale (VAS) values for swallowing difficulty were 8.62 at day 1 and decreased to 3.98 at day 7. The VAS values for pain were 9.14 at day 1, but were reduced to 4.18 at day 7. CONCLUSIONS: Patients with OSAS who have hypertrophy of the tongue base may safely receive a tongue base suspension procedure, which is a minimally invasive method. The postoperative hospital stay is short and the success rate is high, as shown with both PSG and MRI.

Palatal Pillar implants for the treatment of simple snoring.

OBJECTIVES: In this study the efficacy of palatal implants for treatment of snoring was evaluated. PATIENTS AND METHODS: Seventeen patients (10 males, 7 females; mean age 49.2+/-7.8 years; range 31 to 66 years) with primary snoring and an apnea-hypopnea index of less than 15 were treated with palatal implants after clinical and endoscopic examination. Snoring-related symptoms were evaluated at baseline and 90 days after surgery and polysomnography was performed. Patients and their spouses completed questionnaires and visual analog scales (VAS) evaluating snoring, apneas, and the intensity, duration, and social effects of daytime sleepiness at baseline and 90 days after surgery. Pre- and postoperative assessment results were compared. RESULTS: Epworth sleepiness scale score was significantly decreased in the postoperative period (p<0.05). Postoperative mean VAS snoring, apnea, and daytime sleepiness scores were also significantly improved (p<0.01). No patients reported worsening of apnea, 5.9% of patients reported no change in apnea, and 94.1% of patients reported a marked decrease in apneas. In the postoperative period, 76.4% of patients reported reduced snoring, and 88.3% of patients reported reduced daytime sleepiness. CONCLUSION: Palatal implants have been demonstrated to be a safe and effective treatment for snoring with minimal patient discomfort. Establishing realistic pretreatment expectations can maximize patient satisfaction.

Comparison between tonsillectomy with thermal welding and the conventional 'cold' tonsillectomy technique.

BACKGROUND: The aim of this study was the evaluation of length of the procedure, anaesthesia, the amount of the intraoperative fluid required, total blood loss and postoperative pain of the 'thermal welding system tonsillectomy (TWS)' compared with the conventional 'cold dissection tonsillectomy'. METHODS: Fifty patients aged between 3 and 28 years were included in this prospective controlled study. Extracapsular tonsillectomy with TWS was carried out on 25 patients and conventional 'cold' extracapsular dissection complete tonsillectomy was carried out on the other 25 patients. Haemostasis was achieved with packing and 3/0 chromic catgut suture is used to treat the persistently bleeding sites in the 'cold' tonsillectomy group. Intraoperatively, the duration of the procedure, anaesthesia, the amount of the required intraoperative fluid, the total blood loss and the number of sutures were documented for each patient. In the hospital, the postoperative amount of intravenous fluids, oral intake (timing of onset and amount), the duration and the total dose of analgesics were recorded. Daily assessment included the type of diet, the level of appetite, the total number of analgesics, the presence of fever, the time required to return to normal activity and the pain score (twice daily). Pain was measured by means of Faces Pain Scale and Visual Analogue Scale. RESULTS: There was a statistically and clinically significant difference in the operating time in the intraoperative blood loss in favour of the conventional tonsillectomy group (P > 0.05). Although there was no statistically significant difference between the two groups for the postoperative evening pain scores (P > 0.05), there was a statistically significant difference for the morning pain scores (P < 0.05) in the first 2 days postoperatively (P > 0.05) and in the level of appetite in the first postoperative day (P > 0.05). The other outcome measures did not show any statistically significant difference. CONCLUSION: When we compared TWS with the conventional 'cold' dissection tonsillectomy, we found that TWS tonsillectomy offered an innovative new tonsillectomy method with significantly reduced blood loss and reduced surgical time and without any increase in the postoperative pain. It was a useful method for tonsillectomy.
