Management of facial paralysis resulting from temporal bone fractures: Our experience in 115 cases.

OBJECTIVE: The goal of this study was to review decision factors and overall results regarding surgical and nonsurgical management of post-traumatic facial nerve paralysis (FP). STUDY DESIGN: A retrospective study and literature review were performed. METHODS: Between 1984 and 1990, 115 cases of post-traumatic FP were handled. Patients were evaluated through clinical, audiologic, radiologic, and electromyogram assessment. Depending on examination results, patients were treated either medically or surgically through total facial nerve decompression. RESULTS: Forty-nine of the 50 medically treated patients experienced a normal or subnormal facial function recovery (grade I-II). Of the 65 (56.5%) surgically treated patients, 52 (80%) had immediate, 2 had delayed, and 11 (17%) had unknown delay-associated FP. The approaches chosen were middle fossa and transmastoid (75.3%), translabyrinthine (10.7%), or pure transmastoid according to facial nerve nonmotor branch evaluation, hearing, location of the fracture line, and the patient's general condition. Lesions were predominantly found in the geniculate ganglion area (66.2%). A nerve gap was found in only 13.8% of the cases. At 2 years after surgery, 93.8% had a grade I to III recovery. None had grade V or VI. CONCLUSION: The rarity of severe nerve lesions encountered in surgically treated patients raises the question of better selection of candidates for surgery. Surgery is clearly indicated when FP is total, is of immediate onset, and is associated with a bad prognosis electromyogram pattern. In other settings, decisions are to be made based on high-resolution CT data and electromyogram results, thanks to a clinical survey and second electromyogram evaluation.

[Malignant or necrotizing otitis externa: experience in 22 cases]. / Otites externes "malignes" ou nécrosantes progressives.

Malignant or progressive necrotizing otitis extrema is an uncommon but severe infectious condition of the external auditory canal. Over a period of four years, we treated 22 patients: 60% had diabetes (1/4 insulin dependent) and 13% were immunodepressed. The causal germ was Pseudomonas aeruginosa in 87% of cases. The pretherapeutic work-up included a computed tomography scan and a technetium scintigraphy to confirm diagnosis and assess extension. Repeated scintigraphies with gallium were used to follow the course under treatment. Medical treatment was used in most cases (16/22) with parenteral antibiotic therapy using a third-generation cephalosporin (ceftazidime or ceftriaxone) and a fluoroquinolone (ciprofloxacin or ofloxacin) and, if there was no contraindication, hyperbaric oxygen. Surgery is not indicated in malignant otitis externa. We had a 95% cure rate with only 10% recurrence. We reviewed the data in the literature on malignant otitis externa and present the important diagnostic, imaging and therapeutic aspects.

[Value of the association of normovolemic dilution and hyperbaric oxygenation in the treatment of sudden deafness. A retrospective study]. / Intérêt de l'association hémodilution normovolémique-oxygénothérapie hyperbare dans le traitement des surdités brusques à partir d'une étude rétrospective.

The multiple treatments of sudden deafness shows how this pathology still remains quite unknown. The authors present a retrospective study of 87 patients treated by normovolemic hemodilution associated to hyperbaric oxygenation. They obtain a total à 60% of significant recovery (ratio between hearing gain and initial hearing loss, above 25%) and in severe hearing loss (threshold between 70 and 90 dB) 60% of good results (ratio above 50%). The importance of the initial form of audiogram and the presence of dizziness as prognostic factors is not confirmed. On the other hand, the evolution of tinnitus is correlated with the deafness and it is a supplementary means to evaluate the therapeutic efficiency. Moreover the persistence of tinnitus represents an important after effect. Sudden deafness still remains a medical emergency and the delay for carrying out any treatment should be as short as possible. On the other hand it is possible to reduce hospital stay by two sessions of hyperbaric oxygenation per day.

[Sudden deafness: a randomized comparative study of 2 administration modalities of hyperbaric oxygenotherapy combined with naftidrofuryl]. / Surdités brusques: étude comparative randomisée de deux modes d'administration de l'oxygénothérapie hyperbare associée au Naftidrofuryl.

Hyperbaric oxygen therapy is one of the numerous therapies which have been proposed in the management of sudden deafness. It is presumptuous to claim the efficiency of any treatment in a pathology where both the origin and the actual rate of spontaneous recovery are unknown. The grounds of therapies are therefore empirical but the need of urgent therapy is dictated by ethics. This study compares the effects of hyperbaric oxygen therapy in two groups of patients; according ot their order in randomization the subjects were treated either at a rate of 1 session or 2 sessions per day. Hyperbaric oxygen therapy was associated with infusion of Naftidrofuryl to counteract the vasoconstrictive effect of increased oxygen pressure in blood. Steroids were also administered simultaneously to avoid, for the same reasons, cerebral oedema. Normovolemic hemodilution (Dauman et al. 1983) was systemically performed in all the patients preliminarily to hyperbaric oxygen therapy, in order to reduce the haematocrit and thus facilitate blood supply. The efficiency and the side effects were similar in the two groups, provided that some principles in the selection and the monitoring of the patients were respected. The rate of 2 sessions of hyperbaric oxygen therapy per day has obvious advantages in view of health policy, but it requires the hospitalization of the patient and should be restricted to the younger subjects.
