Facial paralysis: Clinical practice guideline of the Spanish Society of Otolaryngology. / Parálisis facial: guía de práctica clínica de la Sociedad Española de ORL.

Bell's palsy is the most common diagnosis associated with facial nerve weakness or paralysis. However, not all patients with facial paresis/paralysis have Bell's palsy. Other common causes include treatment of vestibular schwannoma, head and neck tumours, iatrogenic injuries, Herpes zoster, or trauma. The approach to each of these conditions varies widely. The purpose of this guideline is to provide clinicians with guidance on the treatment and monitoring of patients with different causes of facial paralysis. We intend to draft a practical guideline, focusing on operationalised recommendations deemed to be useful in the daily management of patients. This guideline was promoted by the Spanish Society of Otolaryngology and developed by a group of physicians with an interest in facial nerve disorders, including at least one physician from each Autonomous Community. In a question and answer format, it includes 56 relevant topics related to the facial nerve.

Evolution of Patients With Immediate Complete Facial Paralysis Secondary to Acoustic Neuroma Surgery.

OBJECTIVE: To study the evolution of patients with immediate complete facial paralysis after acoustic neuroma surgery in different scenarios and assess different facial reanimations techniques. METHODS: This study included 50 patients with complete facial paralysis immediately after acoustic neuroma surgery. Data were analyzed into 4 groups according to the need and type of reconstruction of the facial nerve, either none, immediate, or on a deferred basis. All patients had intraoperative facial nerve monitoring, and facial nerve function was evaluated according the House-Brackmann (HB) scale. RESULTS: Of all patients with immediate total paralysis, no patients achieved totally normal facial function (grade I), and only 5 (10%) recovered to a grade II. For all groups included, the majority of patients (82%) achieved an acceptable final facial function (grade III HB). In this series, only 2 patients remained with a grade VI facial function. CONCLUSIONS: The possibility of recovering near normal facial function after a grade VI facial paralysis is very low. Procedures like the immediate repair of the facial nerve with an interposed donor graft may provide better facial function in patients with partially injured facial nerve. Even in cases of total section, there are other procedures that can improve the results.

Use of hyaluronic acid gel in the management of cicatricial ectropion: results and complications.

AIMS: To report our experience using hyaluronic acid gel injection in the lower eyelid to treat cicatricial ectropion. METHODS: Clinical records and literature review. RESULTS: Between November 2009 and June 2011, 12 lower eyelids of 11 patients with cicatricial ectropion were treated with hyaluronic acid gel. All 11 patients demonstrated improvement in the eyelid position after treatment but only 3 patients (27.3%) experimented total correction after injection. Although the correction was partial in the majority of the patients, the signs and symptoms associated with conjunctival and corneal exposure improved in all patients. Seven patients (63.7%) developed irregular fullness which resolved over time, but in 4 patients (36.3%) fullness persisted for one year. CONCLUSIONS: In our experience, hyaluronic acid gel is a nonsurgical, minimally invasive and safe technique that improves cicatricial ectropion, but with a poor cosmetic result that limits its use. This treatment could be considered only in patients who decline surgery or are poor surgical candidates, as the aesthetic result would not be acceptable to many.

Use of carotid compression in a patient with arteriovenous malformation.

We report a case of a patient with a high flow arteriovenous malformation (AVM)i n the orbit, who developed a severe compartment syndrome, and was successfully treated with manual carotid compressions. The patient suffered a progressive proptosis, restriction of ocular motility and decreased of the visual acuity of the right eye. Embolization had a high risk of serious complications due to fistula location, so an alternative treatment consisting in carotid compressions was prescribed. Manual carotid compression is a non-invasive alternative technique to treat AVMs in patients with high risk of embolization episodes.

Peripheral primitive neuroectodermal tumour of the orbit.

Peripheral primitive neuroectodermal tumours (pPNETs) are a group of soft-tissue tumours of neuroepithelial origin that arise outside the central and sympathetic nervous system. Orbital location is infrequent, and to the best of the authors' knowledge only 16 cases have been reported in the literature. With this article, the authors report the demographics and clinical characteristics, diagnostic features, differential diagnosis, prognosis and therapeutic options of primary orbital peripheral primitive neuroectodermal tumour, based on their patients and on the cases reported in the literature to date. A differential diagnosis should be made with other small round cell tumours; immunohistochemical and ultrastructural techniques are essential for this purpose. Although bone invasion and extraorbital extension are possible, systemic metastases are uncommon in the cases of orbital pPNETs. Surgery has been the initial treatment in most cases; chemotherapy with or without radiotherapy is considered the best additional treatment. The orbital pPNET could be less aggressive than other forms of pPNETs, since most of the patients reported were alive after the follow-up period (at least 6 months).

Nasolacrimal stents for the treatment of epiphora: technical problems and long-term results.

PURPOSE: To evaluate the long-term effectiveness of nasolacrimal stents for the treatment of obstructive epiphora, and the complications related to the procedure. METHODS: This study is a non-randomized prospective clinical trial. Eighty-five patients underwent fluoroscopally-guided placement of polyurethane stent in 86 lacrimal systems for the treatment of severe idiopathic obstructive epiphora. The sites of obstruction were: sac-duct junction (n = 65), sac (n = 10), and nasolacrimal duct (n = 11). The procedure was performed in an outpatient basis under local anesthesia. Patients were followed for a mean of 24 months (1-84) with clinical examinations and/or dacryocystography. Clinical success was defined as symptoms resolution or improvement, and the patency of the lacrimal system to irrigation. RESULTS: Stent placement was technically successful in 76 (88.4%) eyes. Technical failures (11.6%) were caused by inability to pass the guide-wire through the lacrimal system. Immediate complications occurred in 19 (22%) eyes, were mild and included: self-limited epistaxis (7), mild palpebral hematoma (7), moderate pain (3), lacrimal puncta bleeding (1), palpebral emphysema (1), and false passage (1). Of the 76 inserted stents, 33 (43.4%) became occluded, and 43 (56.6%) remained patent after a mean of 24 months. Mean duration of stent patency was 38 months. Clinical success was achieved in 40 (52.6%) of the successfully implanted stents. CONCLUSIONS: The procedure is well tolerated and can be performed on an outpatient basis. Patency decreases with follow-up, and, in the long-term, the success rate is inferior to that achieved by external dacryocystorhynostomy. However, it many be considered as a valid alternative to surgery in selected patients.
