[Emphysema after cochlear implantation - risk factors and therapeutic options]. / Emphyseme nach Cochlea-Implantation ­ Risikofaktoren und Therapieoptionen.

OBJECTIVE: In case of cochlear implantation seroma, hematoma, local wound infections or vertigo are rare but typical complications. In contrast, emphysema is seldom reported. They can occur after cochlear implantation both in the postoperative healing phase and years later. A therapeutic algorithm does not yet exist. METHODS: We report on 3 patients with subcutaneous emphysema in the area of the receiver-stimulator. An unsystematic review of the literature of cases with emphysema after cochlear implantation highlights possible risk factors and the therapeutic options. RESULTS: The 3 cases developed subcutaneous emphysema 2-11 month after cochlear implantation due to nose blowing or CPAP therapy in obstructive sleep apnea. The current literature reports another 35 cases of emphysema after cochlear implantation. Air insufflation via the Eustachian tube is the most frequently described cause. Diseases of the nose and sinuses, tube dysfunction and obstructive sleep apnea are potential risk factors. Pressure bandage, puncture, tympanic tubes, and surgical revision are common treatments. CONCLUSIONS: Most emphysema can be controlled by conservative methods such as pressure bandaging and behavioral instruction. Punctures should be avoided due to the risk of upcoming infections. The prophylactic use of antibiotics seems dispensable. Surgical revision should be considered especially in cases of pneumocephalus with suspected leakage in the dura. The coverage of the mastoidectomy by a bony cap can be precautious and beneficial in cases with risk factors.

Anthropometric Evaluation of Photographic Images Before and After Functional Nasal Surgery in Patients With Deviated Noses.

BACKGROUND: Numerous techniques for correction of deviated noses have been described. Nevertheless, surgical management is challenging even for experienced rhinosurgeons. Often, a "residual deformity" after functional septorhinoplasty (SRP) due to a deviated pyramid syndrome may remain. OBJECTIVE: Therefore, the purpose of this study was to determine how frequent functional SRP in patients with a deviated nose results in "successful" straightening of the external nose based on standardized angle measurements. Possible influences having a positive or negative effect on the surgical success were identified. METHODS: Photo documentation of 607 patients with deviated noses (304 women, 303 men, median age 30 years) before and after nasal surgery were retrospectively analyzed using standardized angle measurements. The pre- and postoperative photos of the faces were anthropometrically measured. The median follow-up was 6 months. RESULTS: A "straight" deviated nose (I-type) was present in 225 patients (37%), a C-shaped nose (C-type) in 382 patients (63%). More than 75% of the patients presented a facial asymmetry. Based on angle measurements alone, a total of 452 (75%) noses were straightened or postoperatively improved. 155 noses (25%) still showed a biometric deviation. The I- or C-type had no relevant influence on outcome. CONCLUSION: A purely biometric analysis of crooked noses is difficult and its importance is limited due to commonly pre-existing facial asymmetries. The risk of a "residual deviation" after rhinoplasty in patients with deviated noses must not be underestimated. This fact should be addressed as part of the informed consent. In particular, it should be mentioned that the surgical outcome can remain well below the patient's aesthetic expectations. Not rarely, a revision surgery may be necessary.
