Mandibular fracture: analysis of 293 patients treated in the Hospital of Clinics, Federal University of Uberlândia.

UNLABELLED: Mandibular fracture is the second most common facial fracture and there has been a significant increase in number of cases in the last years. Misidentification and inadequate treatment can take to permanent aesthetic or functional deformity. AIM: Evaluate cases of mandibular fracture reduction in the Hospital of Clinics of the Federal University of Uberlândia, from January of 1974 to December of 2002. STUDY DESIGN: Historical cohort. PATIENT AND METHOD: Two hundred and ninety-three cases of reduction of mandibular fractures were retrospectively analyzed according to factors related to: patient, trauma, signs and symptoms, and surgical treatment. RESULTS: There has been a clear tendency of increase of the number of mandibular fractures along the years. There was higher prevalence in male (4:1), with occurrence peak between 20 to 29 years old. The principal causes of fracture in this study were traffic accidents and violence, representing 72.4%. One hundred and thirty-five patients presented only one fracture. The most injured sites were, in decreasing order, symphysis, condyle, angle, body, ramus, and coronoid. We performed closed reduction (28), open reduction (213) and association of the two (11 patients); 56.8% of the patients were treated within the first 3 days; and, 50.4% were discharged from the hospital until the first postoperative day. About 10% of the patients presented complications, being osteomyelitis the most frequent one. CONCLUSION: The incidence of mandibular fractures was remarkably larger in the male sex, during the third decade of life. The most common cause was traffic accident, and symphysis and condyle were the most injured sites. Isolated fractures occurred in over half of the cases. Most of the patients were treated in the first three days and were discharged until the first postoperative visit. Closed reduction was the treatment most commonly employed. The most frequent complication was osteomyelitis.

Detection of Mycobacterium leprae in nasal mucosa biopsies by the polymerase chain reaction.

Several discoveries about leprosy indicate that Mycobacterium leprae transmission mainly occurs by inhalation, and the nose is major port of entry and exit. The present study evaluated the clinical application of PCR for detection of M. leprae DNA in nasal mucosa biopsies in untreated leprosy patients (52) and their contacts (99) from the State Reference Center in Sanitary Dermatology and Leprosy, Uberlandia, MG, Brazil. PCR detection of a 372-base pair DNA fragment from M. leprae was accomplished in 36 (69.2%) patients, from which 34 (91.9%) of them were multibacillaries. Furthermore, PCR was positive in 3 (16.7%) of 18 slit-skin smear negative, 4 (25.0%) of 16 skin lesion BI negative, 8 (33.3%) of 24 nasal mucosa BI negative patients, and 10 of 99 contacts (10.1%). The presence of bacilli in 10.1% of the contacts may potentially reflect an occult leprosy, and these patients must be accompanied, followed by a chemoprophylaxy treatment. Considering all PCR results against clinical and BI classification of patients and controls, we have found a sensitivity of 69.2%, a specificity of 89.9%, and an accuracy of 82.8%. It has been demonstrated here through PCR of nasal biopsies that the bacillus invades the mucosa, passing through the nasal inferior turbinate to reach peripheral blood. Therefore, the molecular investigation of invasive nasal biopsies by PCR tests has proven to be useful in defining patients of higher risk of transmission and risk-group contacts, which is an important step to reach the World Health Organization objective towards the elimination of leprosy as a public health problem.

Endoscopic decompression of the optic nerve in pseudotumor cerebri.

Pseudotumor cerebri is a neurological condition in which patients develop headaches and visual loss that may not be successfully treated with medication. In these cases surgery is indicated, and decompression of the optic nerve is the preferred surgical procedure. We report a case of decompression of the optic nerve performed through an endonasal endoscopic approach in a patient with pseudotumor cerebri where enhancement of visual acuity was successful. To our knowledge, no previous investigators have reported this approach to treat pseudotumor cerebri.

Vision recovery following nasopharyngeal angiofibroma excision.

'Juvenile' nasopharyngeal angiofibroma is a locally aggressive, yet histologically benign, vascular neoplasm. This neoplasm accounts for less than 0.5% of head and neck neoplasms. We report an unique case of a 14-year-old male with a nasopharyngeal angiofibroma compressing the optic nerve and causing great visual impairment. The tumor was a red lobulated mass in left nostril, invading maxillary sinus, anterior and posterior ethmoid sinus, sphenoid sinus, and cavum area. Midfacial degloving approach and total excision of the tumor resulted in almost completely visual recovery. Optic nerve decompression was not performed. We consider that an early diagnosis, an adequate approach, total tumor excision, and efforts by a team of sub-specialists are most likely to yield optimal results.

Nasopharyngeal angiofibroma in an elderly woman.

"Juvenile" nasopharyngeal angiofibroma is a locally aggressive, yet histologically benign, vascular neoplasm. This neoplasm accounts for less than 0.5% of neoplasms of the head and neck and occurs almost exclusively in adolescent males. We report a rare case of a 64-year-old woman with a red lobulated mass in the right nostril, diagnosed as nasopharyngeal angiofibroma on postoperative histopathologic and immunohistochemical analysis.

Surgical maneuvers performed on rhinoplasty procedures carried out at an otorhinolaryngology residency program.

UNLABELLED: Rhinoplasty is one of the most challenging surgical procedures, due both to the diversity of the techniques and to the difficulty in foreseeing long-term outcomes. Each patient has a different nasal anatomy, dictated by genetic inheritance--race, thus requiring a different technique for each case. The international literature emphasizes the techniques used for the Caucasian nose, which is rarely seen in our region. AIM: Evaluate and discuss surgical maneuvers used on rhinoplasty procedures performed on local patients at our ENT residency services. MATERIALS AND METHODS: We evaluated the operative notes from all patients submitted to rhinoplasty at the Residency Program on Otorhinolaryngology at the Federal University of Uberlândia, from December 2003 to June 2004. RESULTS: One hundred and sixty-six patients were submitted to rhinoplasty, in which marginal incisions were performed in 118 (71.1%), with the delivery technique performed on the inferior lateral cartilages and some procedures carried out on them (strut, sheen, sutures, etc). Only 45 patients (27.1%) were submitted to basic rhinoplasty and 3 (1.8%) to open rhinoplasty. CONCLUSION: Most of our patients demanded additional procedures, and the "basic rhinoplasty", commonly performed on the Caucasian nose was an exception on our patients.

Earlobe cleft reconstructive surgery.

UNLABELLED: The earlobe occupies a unique position among facial structures and has its own importance when we consider the secular tradition of wearing decorations and jewels on it. AIM: To present and discuss the technique used in the Departments of Otolaryngology of the Federal University of Uberlândia (FAMED-UFU) and the Hospital Santa Genoveva, in the treatment of earlobe clefts. PATIENT AND METHODS: Twenty-five patients (35 ears) with earlobe clefts were evaluated, from January 2003 to May 2005. In all these cases we used the technique we call "Surgery of the Ear Ring". RESULTS: Of the 35 cases, 32 presented satisfactory results, 1 presented with an aesthetic deficit only noticed by the surgeon, and 2 presented aesthetic deficits noticed by both the patient and surgeon, needing a "second look" surgery. In these, there was a notch in the lower free border. The other case with deficit was a functional one caused by the closing of the ear lobe hole. CONCLUSIONS: We consider this technique an innovative one, of easy accomplishment, and with good aesthetic and functional results. Therefore, it is the authors preferred technique for the correction of earlobe clefts.

Subperiosteal facelift: a 5-year experience.

UNLABELLED: In classic rhytidectomy, there is little improvement in the center portion of the face. Aesthetic correction of malar prominence ptosis, accentuated nasolabial line, and jawl line, in most of the cases, require different approaches, such as the subperiosteal facelift. AIM: to show the cases and to evaluate the results and complications of subperiosteal facelift in the our service. PATIENTS AND METHODS: From January of 2001 to December of 2005, 25 patients, ranging from 44 to 60 years, 24 females, were submitted to subperiosteal facelift. Results and complications were retrospectively appraised. RESULTS: Of these, 20 presented satisfactory results, 4 presented aesthetic deficits noticed both by the patients and by the surgeon, and 1 presented aesthetic deficit needing revision surgery. All the patients presented improvement of nasolabial line, malar prominence and better definition of the jawl line. Revision surgery was necessary in one patient that referred little improvement. Four patients presented skin retraction in malar area due to the suspension sutures. A patient presented transitory paralysis of the front branch of the facial nerve. CONCLUSION: Subperiosteal facelift with temporal access has shown satisfactory results in the great majority of the cases.

Endoscopic frontoplasty: 3-year experience.

UNLABELLED: Endoscopic forehead lift (EFL) represents a significant progress, even replacing the classic coronal and pretriquial techniques. AIM: To demonstrate a series of cases and to evaluate results and complications with EFL in the Department of Otorhinolaryngology of the Federal University of Uberlândia. MATERIALS AND METHODS: From January 2001 to January 2004, 67 patients were submitted to EFL, and 7 of these were submitted to the so called "triangles technique". Their ages ranged between 38 and 59 years; and 65 (97%) were females. RESULTS: Of these, 56 patients presented satisfactory result and 2 presented aesthetic deficits noticed by the surgeon and the patient. Of the 7 patients submitted to the "triangles technique", all showed satisfactory results. All the patients had improvements on their ptosis of the lateral and glabellar third of the brows and reduction in vertical and frontal wrinkles. Revision surgery was necessary in 2 patients that had ptosis recurrence. There was one unilateral paralysis of the front branch of the facial nerve. With the "triangles technique", 5 patients presented visible scars. CONCLUSION: EFL is a technique that produces satisfactory results in the great majority of patients, with low complication rates.
