1/50. A rare case of upper airway obstruction in an infant caused by basal encephalocele complicating facial midline deformity.A four-month-old male infant with basal encephalocele of the transsphenoidal type presented with upper airway obstruction and facial midline deformity, including cleft lip, cleft palate, hypertelorism and exophthalmos. Basal encephalocele is a rare disease, and usually not detectable from the outside. In this case, initially the cause of an upper airway obstruction was considered to be posterior rhinostenosis, and posterior rhinoplasty with inferior nasal conchectomy was scheduled. However, in preoperative examination, computed tomography (CT) and magnetic resonance imaging (MRI) revealed a bony defect in the sphenoidal bone and a cystic mass in communication with cerebrospinal fluid, herniating into the nasal cavity through the bony defect. The mass was diagnosed as a transsphenoidal encephalocele, the scheduled operation cancelled, and tracheostomy performed for airway management. The possibility of basal encephalocele should be considered in the case of upper airway obstruction with facial midline deformity.- - - - - - - - - - ranking = 1keywords = cleft palate, palate, cleft (Clic here for more details about this article) |
2/50. Oronasal fistula repair with three layers.We present an innovative method for closure of oronasal fistulas involving a three-layer repair, consisting of septal mucosa flap, bone or cartilage graft, and palatal mucosa flap. The septal mucosa flap closes the nasal side of the defect. This is an inferiorly based flap along the nasal floor and consists of septal mucosa from the side opposite the oronasal fistula. A slit is created in the remaining layers of the nasal septum, allowing the flap to be delivered into the defect. When the septal flap is folded down in this fashion, it exposes nasal septal bone and cartilage. The bone and cartilage are harvested and are used to create the middle layer of the three-layer fistula repair. The oral layer of the repair is provided by a palatal mucosa transposition flap. This method allows the bone/cartilage graft to be sandwiched between two vascular layers. We have successfully used the three-layer repair on three patients. All of the oronasal defects were 2 cm in size. All patients are at least 1 year after repair with 100 percent closure; thus, no oronasal leakage. The flaps both septal and palatal resulted in no morbidity once healed. Specifically, the surgically created slit in the nasal septum is well mucosalized and barely discernible. Also, no nasal obstruction occurs from the septal flap on the floor of the nose. We perform the procedure on an outpatient basis. The three-layer repair can be used in adult patients with oronasal fistulas of the middle and posterior hard palate up to 3 cm in size. This technique is not recommended for children.- - - - - - - - - - ranking = 0.38525374392951keywords = palate (Clic here for more details about this article) |
3/50. The dental management of a patient with a cocaine-induced maxillofacial defect: a case report.There are several dental complications associated with cocaine abuse, including adverse reactions to dental anesthetics, post-operative bleeding, and cellulitis, which can lead to necrosis of orbital, nasal, and palatal bones. Following is a report of the initial treatment rendered to a patient who had destroyed most of her hard palate over a ten-year period of cocaine abuse. There are no classic socio-economic or educational profiles for abusers of cocaine. Drug abuse victims may present as patients in any dental office. Though there are certain classic physiological and psychological symptoms of their condition, they may not display symptoms at all.- - - - - - - - - - ranking = 0.38525374392951keywords = palate (Clic here for more details about this article) |
4/50. Closure of an oronasal fistula in an irradiated palate by tissue and bone distraction osteogenesis.Uses for distraction osteogenesis in the craniofacial skeleton have expanded during the last decade. It has become an important rung in the reconstructive ladder for correction of difficult defects. Distraction of irradiated bone has been successfully performed in an animal model but has not been reported in human subjects. We present a case of distraction osteogenesis in a patient with multiple failed reconstructive attempts to close an irradiated palatal defect. An additional benefit included improvement in support of the upper lip from bone transported and the potential for placing dental implants.- - - - - - - - - - ranking = 1.541014975718keywords = palate (Clic here for more details about this article) |
5/50. Midfacial osteomyelitis in a chronic cocaine abuser: a case report.We describe the case of a 56-year-old man who was admitted for treatment of a progressive destruction of his hard palate, septum, nasal cartilage, and soft palate that had been caused by chronic cocaine inhalation. biopsy of the bony septum revealed acute osteomyelitis and an extensive overgrowth of bacteria and actinomyces-like organisms. There was no evidence of granuloma or neoplasm. The patient received intravenous ampicillin/sulbactam for 6 weeks, followed by lifetime oral amoxicillin. When there was no further evidence that destruction was progressing, the patient underwent nasal reconstruction with a cranial bone graft. The surgery was completed with no complications. To our knowledge, this is the first reported case of midfacial osteomyelitis associated with chronic cocaine abuse. The severity of this patient's complications, coupled with the success of his reconstructive surgery, makes this case particularly interesting. We believe that it is important for physicians to understand that septal perforation in a cocaine abuser should not be underestimated because it could result in a secondary bone infection. Nasoseptal destruction secondary to intranasal cocaine abuse is a result of cocaine's vasoconstrictive properties, and a decrease in the oxygen tension of intranasal tissue can facilitate the growth of anaerobic pathogens.- - - - - - - - - - ranking = 0.77050748785902keywords = palate (Clic here for more details about this article) |
6/50. Complications of intranasal prescription narcotic abuse.The abuse of drugs via an intranasal route is an increasingly prevalent pattern of behavior. In the past year, a number of patients received care at our institution for complications resulting from the previously unreported phenomenon of intranasal prescription narcotic abuse. This report describes the clinical manifestations of this form of drug abuse in 5 patients. Their symptoms consisted of nasal and/or facial pain, nasal obstruction, and chronic foul-smelling drainage. Common physical findings were nasal septal perforation; erosion of the lateral nasal walls, nasopharynx, and soft palate; and mucopurulent exudate on affected nasal surfaces. In addition, 2 of the 5 patients had invasive fungal rhinosinusitis, which appears to be a complication unique to intranasal narcotic abuse.- - - - - - - - - - ranking = 0.38525374392951keywords = palate (Clic here for more details about this article) |
7/50. Midline nasal and hard palate destruction in cocaine abusers and cocaine's role in rhinologic practice.Intranasal cocaine abuse can lead to destruction of the palate and perforation of the nasal septum. The pathophysiology of cocaine-induced midline destructive lesions is multifactorial and includes local ischemia secondary to vasoconstriction, chemical irritation from adulterants put in "cut" cocaine, and infection secondary to trauma, impaired mucociliary transport, and decreased humoral and cell-mediated immunity. cocaine abuse should be suspected in patients with a palatal or septal perforation of unknown etiology.- - - - - - - - - - ranking = 1.9262687196475keywords = palate (Clic here for more details about this article) |

9/50. Simultaneous cortex bone plate graft with particulate marrow and cancellous bone for reliable closure of palatal fistulae associated with cleft deformities.OBJECTIVE: The purpose of this study was to evaluate the effectiveness of simultaneous cortex bone plate (CBP) graft with particulate marrow and cancellous bone (PMCB) graft for reliable closure of palatal fistulae associated with alveolar clefts. DESIGN: Following standard secondary bone graft preparation of the cleft site, CBP harvested from the medial iliac crest was inserted into the palatal deficiency. This was followed by suturing the palatal mucosa. PMCB was then packed between the cortical bone and the reconstructed nasal floor. SETTING: Ten consecutive patients with palatal fistula were operated on at tokyo Medical and Dental University Hospital from 1998 to 2000. Primary palatal repair was performed in 7 out of 10 patients at our center and in 3 out of 10 patients at other hospitals. patients: Ten patients (6 boys and men, 4 girls and women) with a palatal fistula associated with an alveolar cleft were studied. Ages ranged from 12 to 26 years. INTERVENTIONS: All patients underwent simultaneous CBP graft with PMCB graft for closure of palatal fistula under general anesthesia. RESULTS: Complete closure of palatal fistulae were obtained in 8 out of 10 cases. A very small asymptomatic fistula remained in one patient. Total necrosis of the labial flap with a residual palatal fistula occurred in one patient. CONCLUSIONS: Simultaneous CBP graft with PMCB graft could be more reliable than PMCB alone for closure of a cleft associated palatal fistula.- - - - - - - - - - ranking = 0.89578249181793keywords = cleft (Clic here for more details about this article) |
10/50. Microsurgical tissue transfer for rehabilitation of the patient with cleft lip and palate.OBJECTIVE: Three case reports of microsurgically revascularized tissue transfer for secondary closure of complex oronasal fistulae in cleft lip and palate patients are reported. One scapular and two radial forearm flaps were used in that respect; the scapular flap was transferred without a skin paddle and was left for secondary epithelialization whereas iliac crest bone was transplanted in the two patients with the forearm flaps in a further surgical step. CONCLUSIONS: These microsurgical flaps represent solutions in selected cases of oronasal fistulae in patients with cleft lip and palate with extensive scarring, large defects, or both. Alternative free flaps of the vast spectrum available today, however, also deserve consideration.- - - - - - - - - - ranking = 2.9833593324405keywords = palate, cleft (Clic here for more details about this article) |
