Idiopathic Facial Paralysis: A Randomized, Prospective, and Controlled Study Using Single‐Dose Prednisone Versus Acyclovir Three Times Daily

In a prospective, controlled, and randomized study, we compared the outcome of 101 Bells palsy patients treated with acyclovir (54 patients) or prednisone (47 patients). The acyclovir dosage was 2400 mg (800 mg three times a day) for 10 days, and prednisone was given as a single daily dose of 1 mg/kg of body weight for 10 days and tapered to 0 over the next 6 days. Minimum follow‐up was 3 months in all patients. Patients in the prednisone group had better clinical recovery than those treated with acyclovir. Less degree of neural degeneration was observed in the prednisone group compared with acyclovir patients. The incidence of sequelae was the same in both groups. According to these results, in a 10‐day treatment cycle acyclovir given 800 mg three times is not as useful as prednisone given 1 mg/kg of body weight once a day in patients with idiopathic facial nerve paralysis.

Factors Related to Nerve Injury and Hypocalcemia in Thyroid Gland Surgery

To identify potential risk factors related to complications after thyroidectomy, a study was designed that included 675 patients. Recurrent laryngeal nerve (RLN) paralysis, hypocalcemia, serohematoma, wound infection, and postoperative hemorrhage were evaluated. The rate of paralysis of the RLN was calculated on nerves at risk for hypocalcemia (n = 890) in patients undergoing bilateral procedures or unilateral procedures if they had previously undergone a contralateral operation (n = 321). Multivariate analysis was used to identify the relationships between the variables included in the study. All statistical tests received the same level of significance of 0.05. Permanent hypocalcemia occurred in 2.2% of the patients, whereas unilateral paralysis of the RLN developed in 0.9%. Mortality was 0.1% in this series. The RLN paralysis had a significant relationship with preoperative diagnosis of malignancy (P < 0.03). Likewise, hypocalcemia was related to sex and surgical procedure (P < 0.03). Serohematoma was linked with age (P < 0.001), and hemorrhage was associated with previous radiation of the neck (P < 0.03). (Otolaryngol Head Neck Surg 2001; 124:111-4.)

Seasonal patterns of idiopathic facial paralysis: A 16-year study

The annual frequency of Bells palsy in 16 consecutive years was investigated in a 465,000-person health area in Madrid, Spain. The annual incidence of Bells palsy per 100,000 population was found to be 24.1. The male-to-female ratio was 46:54. Seasonal difference in the incidence was noted in our series with fewer cases during summer. According to these results, the illness in Spain seems to have a similar incidence to that in Western countries. In addition to this, Bells palsy does not have an infectious epidemiologic pattern in our country, but its frequency decreases in warm weather.

Neurological complications following functional neck dissection

A retrospective study was done to assess the incidence and factors associated with neurological complications in patients who have undergone a functional neck dissection (FND). Four hundred forty-two epidermoid cancer patients operated on from January 1984 to December 2002 were included in the study. Clinical parameters, neurological sequelae, and other complications were evaluated in all cases. The incidence of neural damage was calculated on the nerves at risk ( n =714). Paralysis of the 11th nerve occurred in 12 cases (1.68%). A lesion of the marginal branch of the 7th cranial nerve was observed in nine cases (1.26%). Bernard-Horner’s syndrome and hypoglossal nerve paralysis were noted in four and three cases (0.56 and 0.42%), respectively. Thus, the incidence of neurological sequelae after FND is low. Neurological complications were not associated with either clinical parameters or non-neurological complications ( P >0.05). None of the factors studied can predict the appearance of neural problems in the postoperative period.

Extracapsular Spread and Desmoplastic Pattern in Neck Lymph Nodes: Two Prognostic Factors of Laryngeal Cancer

The influence of extracapsular spread (ECS) and a desmoplastic pattern (DP) of metastatic cervical lymph nodes in patients with laryngeal cancer is presented. The study includes 128 patients surgically treated between 1984 and 1992 for squamous cell carcinoma of the larynx with pathologically proven lymph node metastasis. The results were studied from 2 major standpoints: survival and recurrence. The 3-year survival rates were as follows: patients without ECS 73.4%, and with ECS 28.9% (p < .001); patients without a DP 76.9%, and with a DP 43.3% (p < .03). Also, the 3-year recurrence rates in the neck showed significant differences: patients without ECS 10.7%, and with ECS 49.6% (p < .001); patients without a DP 10%, and with a DP 31.6% (p = .1142). Postoperative radiotherapy did not appear to improve the outcome.

Postoperative Radiotherapy in Patients with Positive Nodes after Functional Neck Dissection

A study was designed to assess the usefulness of postoperative radiotherapy (RT) in patients with surgically treated laryngeal and hypopharyngeal cancer with histologically proven positive neck nodes. Patients underwent operation between 1984 and 1995, with functional neck dissection (FND) being part of the treatment in all cases. The selection criteria included squamous cell carcinoma, negative margins for the primary tumor, and no previous treatment. For evaluation purposes, patients were divided into 2 groups: surgery alone versus surgery with postoperative RT. Eighty-three patients fulfilled the inclusion criteria and entered the study. All but 1 of the patients were men. The mean age was 58 years (range, 35 to 77 years). A multivariate analysis was used to analyze the prognostic parameters selected by univariate analysis, eg, age, alcohol, tumor location, T and N stages, and presence or absence of extracapsular spread and a desmoplastic pattern. Postoperative RT was not selected by univariate analysis as a prognostic factor, but was included in the multivariate analysis in order to assess its impact on survival and recurrence rates. Using the statistical method of multivariate analysis, we could not find evidence of a benefit to survival or local recurrence rates with postoperative RT in this series. Patients younger than 55 years and those with extracapsular spread had a decreased survival rate and a higher neck recurrence rate, irrespective of the treatment method.

Objectives: To assess the patency and flow of the internal jugular vein after functional neck dissection.

Analysis of the causes of immediate unanticipated bleeding after pediatric adenotonsillectomy

OBJECTIVES To assess the incidence of unexpected postoperative bleeding in children undergoing adenoidectomy and/or tonsillectomy (T&A), and to investigate its possible undetected haematological causes. METHODS We prospectively collected all patients under 14 years of age with a normal preoperative haematologic work-up (activated partial thromboplastic time, prothrombin time, fibrinogen, and platelet count), who underwent surgery of adenoids and/or tonsils at our institution between January 1997 and November 2000. RESULTS There were 1516 cases that accomplished the inclusion criteria in the period of survey. Thirteen patients bled after surgery. This represents an incidence of 0.8% of immediate postoperative haemorrhage among the 1516 procedures analyzed. No statistical differences were found between bleeding and non-bleeding patients according to age, sex, and type of procedure (P>0.05). In 6 of the 13 bleeding patients (46.1%) an alteration of the coagulation system was subsequently found: 5 von Willebrands disease, and 1 releasing thrombopathy. CONCLUSIONS The incidence of bleeding after adeno and/or tonsillectomy at our institution is comparable with series previously reported in the current medical literature. In nearly one half of the cases, undetected coagulation diseases (mainly von Willebrands disease) are diagnosed after surgery in the haematological study.

Polymorphous low-grade adenocarcinoma of the tongue

Primary adenocarcinomas of the oral cavity in minor salivary glands are distinctive lesions which can be subclassified according to their growth patterns or histomorphology. Polymorphous low-grade adenocarcinoma (PLGA) of minor salivary tissue has been recognized as a distinct entity. We report an unusual case of PLGA of the tongue. Only a few previous cases have been reported in the English literature. The treatment is discussed and a review of the current literature concerning this tumour is included.
