Short-term results using Kurz titanium ossicular implants.

The efficiency of titanium middle ear prosthesis for ossicular reconstruction in chronic ear disease is investigated in a Scandinavian two-center retrospective study from a Norwegian tertiary otology referral center and a Finnish otology referral center. Retrospective chart reviews were performed for procedures involving 73 titanium prostheses between 1999 and 2004. All patients that underwent surgery including the Kurz Vario titanium prosthesis were included in the study, 38 procedures including the partial ossicular replacement prosthesis (PORP) and 35 procedures including the total ossicular replacement prosthesis (TORP). Mean follow-up was 14 months. The ossiculoplasty was performed alone (29 patients) or in combination with other chronic ear surgery procedures (34 patients). Comparisons of preoperative and postoperative pure tone averages (0.5, 1, 2, and 3 kHz) according to AAO-HNS guidelines are presented, as well as data for different PTA definitions. Otosurgery procedures, complications, revisions, and extrusion rates are reported. A postoperative air-bone gap (ABG) of <or=20 dB was obtained in 77% of the patients, 89% for the Bell (Porp) prosthesis, and 63% for the Arial (Torp) prosthesis. Overall mean pure tone averages improved 20.6 dB with ABG improvement of 19.3 dB. The overall extrusion rate was 5% (4 patients). Titanium prostheses have been easy and fast to handle and effective implants for reconstruction of the ossicular chain. We found no difference between reconstruction with or without cholesteatoma surgery during the same procedure. The combination of CWD and Torp gave significant inferior hearing thresholds as compared to Torp/CWU and Porp/CWD combinations.

Local bupivacaine-epinephrine infiltration combined with general anesthesia for adult tonsillectomy.

CONCLUSION: Use of a solution of bupivacaine (5 mg/ml)-epinephrine (5 microg/ml) (BE) is beneficial in reducing intraoperative bleeding and decreasing the operation time in adult (adeno)tonsillectomy patients. OBJECTIVE: Pain and intra- and postoperative bleeding are problems associated with tonsillectomy/adenotonsillectomy. In order to make tonsillectomy/adenotonsillectomy better suited to outpatient surgery, solutions to these problems should be found. One possibility may be the combination of local and general anesthesia. The aim of this study was to find out if such a combination is beneficial in tonsillectomy/adenotonsillectomy. MATERIAL AND METHODS: We performed a prospective, randomized, double-blind, controlled study on 64 adult (adeno)tonsillectomy patients to investigate the possible benefits of infiltrating the peritonsillar space with a BE solution. RESULTS: In the recovery room, the BE group experienced less pain than a control group infiltrated with saline; subsequently there was no significant difference between the groups concerning pain. The average volume of intraoperative bleeding and the operation time were significantly smaller in the BE group. Postoperative bleeding from the tonsillar fossae occurred in 19% (6/31) of the patients in the BE group and in 18% (6/33) in the saline group.

Esophageal pressure monitoring in detection of sleep-disordered breathing.

OBJECTIVE: The aim was to study the value of esophageal pressure monitoring combined with limited polygraphic recording (oxygen saturation, respiratory and leg movements, airflow, body position, and snoring sound) in diagnosis of sleep-disordered breathing. STUDY DESIGN: A prospective study of consecutive patients with snoring was carried out. METHODS: Sixty-seven patients underwent an overnight study on ward. Patients with normal oxygen desaturation index and any periodic breathing disturbances combined with elevated esophageal pressure were further studied with complete polysomnography. RESULTS: The patient compliance with esophageal catheter was 87%. Esophageal pressure monitoring increased effectively the detection of sleep-disordered breathing with limited polygraphic recording. Sixty-seven percent of the patients with normal oxygen desaturation index and respiratory-related esophageal pressure variation had sleep-disordered breathing on complete polysomnography. Increased esophageal pressure variation was significantly related with oxygen desaturation index and obstructive sleep apnea diagnosis (P <.001). All together, 48% of the mainly nonobese snorers had objective findings of sleep-disordered breathing. Patients with upper airway resistance syndrome were few. Fifteen percent of the patients had periodic leg movements. Neither subjective or objective sleepiness nor snoring or obesity adequately exposed sleep-disordered breathing in this material. CONCLUSION: Esophageal pressure monitoring increases markedly the diagnostic value of limited polygraphic recording as a screening study for sleep-disordered breathing.
