[Surgery for Atresia auris. Retrospective study of our results and correlation with Jahrsdoerfer prognostic criterium].

OBJECTIVES: The study goal was to evaluate the hearing follow up results in patients who underwent surgery for congenital aural atresia. We studied hearing results and correlated them with Jahrsdoerfer prognostic classification. Protocols management of unilateral and bilateral atresia auris are written considering to our results and other authors. METHODS: We conducted a retrospective review of 12 ears who underwent surgery for congenital aural atresia between 1989 and 2002. CT scan was used to evaluate Jahrsdoerfer prognostic classification and the correlation with the hearing results. RESULTS: There are significant statistical differences (p = 0.003) in air-bone gap closure before and after surgery, also a lineal significant correlation (p = 0.016) between Jahrsdoerfer prognostic classification and air-bone gap closure. CONCLUSION: Atresiaplasty surgery in individuals with congenital aural atresia can yield good hearing results in selected cases.

[Hearing and speech in children under 2 years of age with a cochlear implant].

BACKGROUND: To compare the auditory abilities and speech performance of children with a profound prelingual bilateral hearing impairment, treated with a cochlear implant (CI) before or after 2 years of age. To analyze the complications arising during the selection process of the children, or as a result of the implantation, programming and follow-up. METHODS: Prospective cohort single-subject repeated-measures study of 130 children who received an implant at our center. The children were divided into two age groups: 0-2 (n=36), and 2-6 years of age (n=94). Preoperative evaluation included: 1. History, physical exploration, and ENT examination. 2. Neuropaediatric examination, family evaluation, and psychological assessment. 3. Auditory brainstem responses. 4. High resolution computed tomogram of temporal bones. 5. Counseling and informed consent. The children were evaluated prior to, and each year following, the intervention (for up to 5 years), using closed and open-set logoaudiometric tests, and speech perception tests. Speech was evaluated according to the Peabody Picture Vocabulary and Reynell general oral expression scale. RESULTS: Auditory and speech perception tests improved significantly in all children after CI, regardless of the follow-up time. The infant's performance was better in the group of early implantees. Speech tests showed that the development of children treated before 2 years of age was similar to that of normal children. No additional complications were observed when compared to CI in older children. CONCLUSIONS: When performed before 2 years of age, CI offers a quicker and better improvement of performance, with no increase in complications when compared with a later intervention.

[Synchronous osteochondroid hamartoma and squamous cell carcinoma of the larynx].

BACKGROUND: Soft-tissue tumors of the larynx are rare, especially hamartomas. Fewer than a dozen well-documented cases have been described. We report the case of a 65 year-old man diagnosed of a synchronous epithelial tumor of the right vocal fold and a soft-tissue tumor of the contralateral lamina of the thyroid cartilage. METHODS: CT scan revealed a low-attenuating, expansive mass involving the left ala of the thyroid cartilage without airway compromise airway. The lesion contained small, scattered calcifications and the mucosa was intact, suggesting a cartilaginous tumor. The patient underwent endoscopic resection of the right vocal fold tumor and subtotal resection of the left ala of the thyroid via median thyrotomy. RESULTS: Pathology revealed a squamous-cell carcinoma of the vocal fold and an osteochondroid hamartoma within the thyroid cartilage. The management of patients with laryngeal lesions suggestive of a cartilaginous nature is discussed. CONCLUSIONS: To our knowledge, this is the first case of a synchronous laryngeal hamartoma and carcinoma reported in the literature.

[General intubation anesthesia in primates for experimental otoneurologic surgery].

INTRODUCTION: We report our experience in anaesthetic and surgical management of primates (M. fascicularis) in an experimental otoneurosurgical procedure. MATERIAL & METHODS: The VIII cranial nerve was bilaterally sectioned in a translabyrinthine approach in 21 adult primates. In 14 animals subsequently, a prototype of auditory brainstem implant was placed unilateraly within the brain stem for surface stimulation of cochlear nuclei. Premedication consisted in an intramuscular mixture of ketamine, midazolam and atropine. Surgical procedure was performed under intubated general anaesthesia, after propofol (1.5 mg/kg) administration and maintained with nitrous oxide and halotane. RESULTS: The mixture of ketamine, midazolam and atropine produced a deep anaesthesia in 4 +/- 1.7 minutes, permitting safe animal handling. Atraumatic nasotracheal intubation without muscle relaxing agents was easily achieved in all animals. Anaesthesia was adequately maintained with nitrous oxide and halotane. Animals did not present any relevant incidents during surgery, and were extubated 10 +/- 2.5 minutes after cessation of gas administration. Post-operatively, no relevant surgical complications occurred. CONCLUSIONS: We report an anaesthetic technique that provides an optimal restrain and anaesthesia for experimental otoneurosurgical procedures with primates. This technique offers a quick recovery and avoids the use of muscular relaxing agents for intubation, and thus could be safely used in other kind of surgical procedures.

[Ultrastructure and pathogenesis of vocal nodules on the vocal cords].

Controlled electron microscopy of the epithelium in voice lesions revealed: thickening and destruction of basement membrane, reduplication of the lamina densa, near absence of normal hemidesmosomes and anchoring fibrils, abundant electro-dense vesicles at the basal cell pole (discharging through the cell membrane), abundant mitochondria, euchromatin and nucleolar prominence. These histologic phenomena suggest that the basal cell layer responds to trauma to its anchorages with metabolic hyperactivity. Therefore the traumatic mechanism should be considered as damaging to the basement membrane.

[Ectopic primitive thyroid papillary carcinoma: report of a fatal case and review of literature].

One percent of excised thyroglossal duct remnants exhibit histologic malignancy, a thyroid papillary carcinoma in 80% of the cases. The prognosis is excellent except for anaplastic types. We report the case of a 44-year-old woman with primitive thyroid papillary carcinoma diagnosed histologically as thyroglossal cyst. Its unusual aggressiveness produced local and regional spread, metastases and the patient's death in spite of treatment: Sistrunk operation, local excision of a recurrence and laryngothyroidectomy. Thyroid histology revealed the absence of carcinomatous foci. We discuss the most noteworthy aspects of the case in relation to other reports.
