[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.

[Closure of Nasal Septal Perforation]. / Der chirurgische Septumperforationsverschluss.

Symptomatic nasal septal perforations can lead to a substantial restriction in the quality of life of patients and present a distinct surgical challenge for the otolaryngologist/head and neck surgeon. Symptomatic patients complain about nasal crusting, recurrent nosebleeds and nasal obstruction. The so called 4 bridge-flap technique including the interposition of autologous ear cartilage presents an established surgical method for closure of a septal perforation. In the present article, the surgical procedure is described in detail.
