AFASIA MOTORA, PARALISIA FACIAL E HEMIPLEGIA DIREITA APOS ABSCESSO DENTARIO A ESQUERDA

The authors report a case of a 6 year old child who presented with dental abscess associated with a parietal and frontal cerebrite, right facial paralysis and motor aphasia. The clinical findings, radiological examination including computerized tomography and type of treatment are presented. At beginning, the patient did not respond to antimicrobial therapy and only after drainage of her dental abscess revealed good clinical evolution.

ASPECTOS ETIOLOGICOS DA HIPERNASALIDADE CONSEQUENTE A PARALISIA DE PALATO MOLE - RELATO DE 6 CASOS

The authors studied the main aspects of etiology of the palate paralysis in six children suffering from soft palate paralysis. They emphasized the importance of multidisciplinary approach in the management of patients with this disease. In the author's cases the most likely etiologies were: neuropathy post-viral epidemic parotitis, tumors localized in the posterior cerebral fossa and idiopathic. They concluded that it is extremely important in these patients a detailed otorhinolaryngologic, neurologic and fonoaudiologic examinations.

ALGIAS CRANIOFACIAIS - UM ROTEIRO PARA O EXAME FISICO DIRIGIDO

Craniofacial pain is a frequent challenge for the physician anamnesis with the goal to obtain specific and useful information about symptoms in craniofacial pain. It can be improved by identifying aching points. In the article, the authors present a practical and specific schedule for physical examination to be applied in patients with chronic pain. This specific schedule, which has proved useful in detecting the exact anatomic sites of pain, has a sequence ordered which includes palpation and inspection of muscles, nerves and arteries.

NEUROFIBROMATOSE DE LINGUA - RELATO DE CASO

Neurofibromatosis may involve any part of the body, including cervical-facial region and intra-oral structures. The authors present a case of neurofibromatosis involving the tongue. They emphasize the need of close follow up of the patients as those lesions often show a high rate of recurrence.

LESOES PRECOCES DA INTUBACAO ENDOTRAQUEAL

The authors studied the early lesions of laryngotracheal mucosa following intubation in 30 dogs who were intubated with high complacent canula during the period of 4 hours. After this period, biopsies of vocal cord, aritenois, cricoid and tracheal rings were performed. The most frequent histological findings were neutrophils and mononuclear inflammatory cell infiltration into the corion, vascular congestion and necrosis of epithelial cells. Based in these findings the authors recommend the use of canula with balonets of high complacence and the endoscopic follow up of the patients after extubation.

REFLUXO GASTROESOFAGICO E SINTOMAS OTORRINOLARINGOLOGICOS

Gastroesophageal reflux and other gastroesophageal diseases produce symptoms in head and neck region leading individuals to search for ear nose and throat consultation. Otolaryngologist may incorporate investigation of reflux in your daily practice. Comments of gastroesophageal reflux and head and neck complaints are done. To illustrate handling of patients suspected of reflux authors relates a case of a dysphagia patient. Close relationship between otolaryngologist and gastroenterologist in reflux investigation is emphasized.

ESTENOSE SUBGLOTICA

In the present study we report the experience of the Department of Otolaryngology-Head and Neck Surgery, University Hospital, Botucatu School in 19 cases of laryngotracheal stenosis. Fifteen cases had subglottic stenosis, one had stenosis of inferior tracheal and subglottic, one had stenosis of trachea and two others had extensive involvement of larynx and trachea due to chronic inflammatory disease. In eleven patients a laryngotracheal reconstrutive technique with costal cartilagem graft was performed with good results. The major technical difficulties, occurring mainly in children, were the withdrawal of the cannula of the tracheostomy due to granulation tissue formation and the subglottic partial stenosis after surgical reconstruction.

MORFOLOGIA DOS RECESSOS TIMPANICOS POSTERIORES

The sinuses of the posterior wall of the tympanic cavity are formed between the bony ridges, bridges and other osseous prominences, remnants of the tympanum widening process. Anatomical limits and relationships of these sinuses were observed in 100 human temporal bones. Many morphological variabilities were found due to different levels of development of the middle ear posterior wall. The most important sinuses of this complex are the Sinus tympani and the Facial Sinus (Facial recess) seen in all cases. The Lateral tympanic sinus is well-formed in 83% of the cases and the Posterior tympanic sinus in 20% of our series.

MANIPULANDO A DISFAGIA DE ORIGEN FARINGOESOFAGICA

Non-neoplastic dysphagia originated from motor deficit in the pharynx and from several disorders in the upper esophagus is studied taking into account the basic mechanisms of deglutition in the pharingoesophageal segment. Three groups of patients with dysphagia were investigated with the purpose of discussing the causes of ths symptom. Clinical examinations and electromanometry of the upper digestive tree, test of the laringeal elevation and clinical test of the bolus propulsion through pharynx were carried out. Emotional alterations, gastroesophageal lesions and motor disturbances in the digestive tree, among other, may cause dysphagia and other associated and secondary symptoms. This study points out the role of Otolaryngology in the investigation of swallowing disorders.

ESTUDO DA UMIDIFICACAO E DO AQUECIMENTO DOS GASES INSPIRADOS DURANTE A VENTILACAO MECANICA NO CAO

The authors studied the effect of temperature and humidity of inhaled gases on the respiratory tract of dogs submitted to mechanic ventilation. According to these two variables, fourty dogs were divided in five groups: -G1: 22-26°C and 17-20 mg H2O.l-1; G2: 27-31°C and 23-27 mg H2O.l-1; G3: 32-36°C and 30-36 mg H2O.l-1; G4: 37-41°C and 40-49 mg H2O.l-1; G5: 42-46°C and 59-65 mg H2O.l-1. The following parameters were evaluated: medial arterial pressure, cardiac frequency, venous pressure of inferior cava (CVP), endotracheal pressure, arterial pH, PaO2, PaCO2, rectal temperature, and the histology of the tracheobronchial tree. In the groups G1 and G5, the endotracheal pressure and CVP presented a slight raise. In the groups G1, G2 and G3, there was no histological modification or progressive hypothermia. The group G5 presented metabolic acidosis and great histological alteration; in this group the rectal temperature remained stable. The group G4 presented great histological alteration and hypothermia. In conclusion, the temperature and humidity of inhaled gases should not be higher than 36°C and 36 mm H2O.l-1, respectively. However, the stability of body temperature only is achieved when the temperature of the inhaled air is 42°C or higher.

Paralisia de corda vocal e cisto de tiroide

The authors present a rare case of vocal cord paralysis following thyroid cyst. The clinical diagnostic and evolution aspects are presented. The importance of precise evaluation of the thyroid gland in all cases of vocal cord paralysis is emphasized.

Carcinoma basaloide - Escamoseo de cebeça: relato de 4 casos

Basaloid squamous carcinoma is an aggressive subtype of squamous carcinoma of superior aerodigestive tract. This tumor has been recently described and it seems to have higher incidence in tongue, hypopharynx and supraglottis. It has more agressive biological behavior than pure type of squamous cell carcinoma. We report 4 cases of this tumor and we present a review of the literature.

Disfagia e alterações emocionais

Swallowing function may be impaired by a number of conditions involving primary or associated emotional distress. When psychogenic dysphagia is suspected, routine investigation using radiological and manometric examination is inappropriate. These cases demand an evaluation of the individual as a whole, interesting the disease as well as the patient's personal problems and concerns. Five cases of patients complaining of swallowing difficulty and showing concurrent emotional distress were studied. Four individuals were anxious and one was depressed. Because of our approach, a close medical-patient-relationship was established. Afterwards, an explanation about the normal swallowing mechanisms and the role of the emotions on it was provided. All patients showed improvement of the symptom in the following 24 hours. Dysphagia can be found in anxiety, depression and conversion hysteria, with high incidence in the urban population of the third world countries. However, several professionals are unaware of these disorders. Our results suggest that this plain approach is an useful tool in managing dysphagic patients and it has validity even in individuals bearing dysphagia due to comproved organic disease. The results also emphasize the importance of the medical patient relationship and the utility of a hollistic evaluation of the disease.
