RESUMO

The most common technique in sound restoration of the middle ear is prosthetic surgery. Hypoventilation of the middle ear may cause adhesive otitis or atelectasis resulting in a higher risk of prosthetic extrusion rate and recurrence of the underlying cholesteatoma. We report long-term results using an island of tragal cartilage as an autologous PORP in selected patients with poor middle ear ventilation. Retrospective chart reviews were performed for procedures involving 52 patients between year 2000 and 2009. All patients that underwent surgery using tragal cartilage interposed between the suprastructure of the stapes and the tympanic membrane were included in this study. Audiological parameters using four frequencies, 0.5, 1, 2 and 3 kHz, according to AAO-HNS guidelines, were assessed pre-and postoperatively. The hearing results on different PTA frequencies were also investigated. We report long-term follow-up of patients with hypoventilated middle ear with a success rate of 71% (ABG <20%). With regards to the ABG, the low frequency component (5 and 1 kHz) showed a significantly (p < 0.05) larger improvement of mean values after surgery as compared to the high-frequency component (2 and 3 kHz). Cartilage island PORP on stapes is a stable and efficient method for selected patients with chronic middle ear disease.

RESUMO

OBJECTIVES: Previous studies have shown that vertigo is the most powerful negative predictor of quality of life in patients with vestibular schwannomas, but the variability in vertigo symptom severity is still poorly understood. We wanted to find out whether vertigo could be related to objective parameters such as tumor size, location, vestibular nerve function, hearing, and postural stability in patients with untreated vestibular schwannomas. STUDY DESIGN: Baseline data from prospective cohort study. SETTING: Tertiary referral center. PATIENTS: Four hundred thirty-four consecutive patients with unilateral VS diagnosed on MRI. Mean age 56 years (range 16-84 yr). Fifty-three percent women. INTERVENTION: Diagnostic, with a medical history, otolaryngological examination, pure-tone and speech audiometry, MRI, posturography, and videonystagmography with bithermal caloric tests. MAIN OUTCOME MEASURE: Dizziness measured on a 100-mm visual analog scale (VAS). Secondary outcome measures were canal paresis and postural imbalance (static and dynamic posturography). RESULTS: Three hundred three patients (70%) completed the VAS. Severe dizziness, defined as VAS 75 or greater, was reported by 9% of the patients. Larger tumors were associated with higher risk of postural instability and canal paresis. Moderate to severe dizziness was associated with postural imbalance and canal paresis, and possibly with small to medium-sized tumors. Postural instability was related to tumor size and canal paresis when measured by dynamic, but not with static, posturography. CONCLUSION: A minority of VS patients experience severe vestibular symptoms related to canal paresis and postural instability. A curvilinear relationship is hypothesized between tumor size and dizziness.

RESUMO

Titanium implants in middle ear surgery were introduced in the late 90s and are now frequently used in middle ear surgery. However, long-term studies of patient outcome are few and have only been published in subgroups of patients. We report the long-term effect of titanium middle ear implants for ossicular reconstruction in chronic ear disease investigated in a Norwegian tertiary otological referral centre. Retrospective chart reviews were performed for procedures involving 76 titanium implants between 2000 and 2007. All patients who underwent surgery using the Kurz Vario titanium implant were included in the study. Audiological parameters using four frequencies, 0.5, 1, 2, and 3 kHz, according to AAO-HNS guidelines, was assessed pre and postoperatively. Otosurgical procedures, complications, revisions, and extrusion rates were analyzed. The study had no dropouts. The partial ossicular replacement prosthesis (PORP) was used in 44 procedures and the total ossicular replacement prosthesis (TORP) in 32 procedures, respectively. Mean follow-up was 5.2 years (62 months). The ossiculoplasties were performed as staging procedures or in combination with other chronic ear surgery. The same surgeon performed all the procedures. A postoperative air-bone gap of ≤ 20 dB was obtained in 74 % of the patients, 82 % for the Bell (PORP) prosthesis, and 63 % for the Arial (TORP) prosthesis. The extrusion rate was 5 %. We conclude that titanium ossicular implants give stable and excellent long-term hearing results.
