Three-dimensional printed definitive cast for a silicone obturator prosthesis: A clinical report.

For patients with head and neck cancer requiring a maxillectomy, obturator prostheses help with quality of life. These patients routinely require adjuvant oncologic treatments with significant adverse effects. Treatment sequelae can leave patients with difficulty speaking and swallowing, reduced salivary function, reduction in maximal incisal opening, and at risk of osteoradionecrosis. A 55-year-old African-American woman presented with significant trismus and reduction in maximal incisal opening after treatment for squamous cell carcinoma of the left maxillary sinus. She had received a left total maxillectomy with adjuvant chemotherapy and radiation treatments. With her reduced opening, she was no longer able to insert her interim obturator prosthesis, which caused difficulty speaking and nasal regurgitation. A cone beam computed tomography scan was made of the patient's maxillectomy defect. From the Digital Imaging and Communications in Medicine file, a definitive cast was 3-dimensionally printed to fabricate a flexible silicone obturator prosthesis. This treatment has allowed the patient to return to a functional quality of life and could help other patients in similar situations.

Felt needs of parents who have a 0- to 3-month-old child with a cleft lip and palate.

OBJECTIVE: To describe the felt needs of parents who have children from birth to 3 months of age with a cleft lip and palate. DESIGN: Parents were interviewed using structured and semistructured questions at 1 week and 1, 2, and 3 months after birth. PARTICIPANTS: Fifteen parents, including 12 mothers and three fathers, of patients with cleft lip and palate aged 0 to 3 months were interviewed. RESULTS: During the first week after birth, the majority of parents needed to know about feeding and surgery. At 1, 2, and 3 months after birth, more information was required, especially on different surgeries during those periods and speech problems. In addition, a number of parents requested funding for every period, and very few had expectations of moral support from health care professionals. CONCLUSIONS: The felt needs expressed in this study changed according to periods of time and mainly concerned feeding, speech problems, and surgery, as well as financial support. The needs of parents, particularly during the transitional period, should be considered as a provision of holistic care for patients with cleft lip and palate and their families.

Presurgical cleft lip management: nasal alveolar molding.

Continued advancement in the comprehensive care of children with cleft lip and palate has resulted in numerous innovative treatment protocols. The cooperation of numerous specialties has continued to expand the options for difficult cases. A high standard for aesthetic and functional results has been established. Presurgical treatment of a cleft alveolus and its associated soft tissues with presurgical orthopedics is just one of these techniques. Differing opinions of the effectiveness, growth disturbances, and additional costs of presurgical molding are often debated, but the concepts should be understood by any cleft surgeon or orthodontist involved in cleft care.

Maxillofacial restoration after head and neck tumor therapy.

Oral and pharyngeal cancers are among the leading cancer sites. Surgery, radiation, chemotherapy, or combination therapies are common treatment modalities. Radiotherapy and chemotherapy cause significant morbidity and long-term irreversible sequelae in the oral cavity. Surgical resection can be mutilating, disfiguring, and deeply affect self-image. Orofacial defects have unique limitations and challenges for both the surgeon and the maxillofacial prosthodontist. Microvascular surgical techniques and the use of osseointegrated implants improve the rehabilitation potential of the various head and neck defects. This article reviews current treatment modalities of tumor therapy, their consequences, and the restoration of maxillofacial defects.

Dynamic presurgical nasal remodeling in patients with unilateral and bilateral cleft lip and palate: modification to the original technique.

OBJECTIVE: To present technical modifications to the original presurgical nasal remodeling appliance introduced in 1991. The purpose of the modifications is to improve the cleft nasal deformity before unilateral and bilateral cleft lip repair. METHOD: The principle behind this technique, known as dynamic presurgical nasal remodeling (DPNR), is the use of the force generated during suction and swallowing. A conventional intraoral plate is built with a nasal extension added to the labial vestibular flange. The nasal extension was modified and consists of three components. The palatal plate is left loose in the mouth to generate a discontinuous but controlled impact directed to the affected nasal structures during suction and swallowing. The principle aim of the DPNR technique in unilateral cases is to improve the deformation of nasal structures by straightening the columella, elevating the nasal tip, and remodeling the depressed cleft side alar cartilages. In bilateral cases, the aims are to elongate the columella and to obtain nasal tip projection. CONCLUSIONS: The modifications introduced in the appliance enhance the original DPNR technique and are effective in ameliorating the initial cleft nasal deformity. This facilitates primary surgical cleft lip and nose correction and improves surgical outcomes in patients with complete unilateral and bilateral cleft lip and palate.

Use of osseointegrated implants in the restoration of head and neck defects.

Osseointegrated implants can be applied to facilitate retention, stability, and support for facial and intraoral prostheses used to restore head and neck defects. At the University of California, Los Angeles, Maxillofacial Prosthetics Clinic, retrospective studies have indicated that in nonirradiated maxillectomy patients, implant survival rates are 82.6 percent. In mandibles reconstructed with fibula free flaps, survival rates are 94.6 percent. Similarly, high implant survival rates have been observed for most sites used to support facial prostheses. Cumulative six-year survival rates for auricular sites exceed 95 percent and for floor of nose sites, success rates exceed 87 percent. However, survival rates are low (53 percent) for implants placed in the frontal bone for retention of orbital prostheses and even lower for irradiated bone sites ranging from 63 percent in the maxilla to 27 percent in the orbit.

A modified muscle-activated maxillary orthopedic appliance for presurgical nasoalveolar molding in infants with unilateral cleft lip and palate.

OBJECTIVE: The purpose of this article is to describe a modified appliance and treatment approach for presurgical nasoalveolar molding in infants with unilateral cleft lip and palate. METHODS: This approach uses a plate held in with outriggers, which prevents the cleft-widening effect of the tongue, helps with tongue tip placement, and utilizes the functional movements of the facial musculature to guide and relocate the major segment medially to its normal position. Nasal molding is undertaken after most of the lateromedial correction of the alveolar position. CONCLUSIONS: This technique helps to improve alveolar position, nasal septum alignment, nasal symmetry, and nasal tip projection prior to lip repair.

The effects of lactation education and a prosthetic obturator appliance on feeding efficiency in infants with cleft lip and palate.

OBJECTIVE: This prospective study examined the effect of lactation instruction and palatal obturation in decreasing time to feed, increasing intake, and on growth in eight breast milk bottle-fed newborn infants with cleft lip, cleft palate, or both. DESIGN: An A, B1, C1, B2, and C2 reversal design was used with eight mothers. In A, baseline data on minutes fed by breast were recorded. In B1, baseline on minutes fed with a Haberman bottle was recorded. In C1, minutes fed following lactation education and palatal obturation were documented. Lactation education was information given to mothers to recognize infant feeding cues and to have infant-led feedings. The palatal obturator was a passive molding appliance. In B2, the obturator was removed and minutes fed noted. In C2, the obturator was returned and lactation support provided. Mothers kept feeding logs, satisfaction was assessed, and infant breast milk intake and flow rate were recorded during each study phase. Routine nutrition evaluation of weight, height, weight for height, and feed volume was completed by a registered dietitian during and following completion of the study. RESULTS: Feeding times decreased with all infants, volume consumed increased with seven of eight infants, and flow rate increased with all infants. Mean feeding times during B1 and B2 phases (Haberman bottle only) were 34.4 and 32.3 minutes, respectively. Mean feeding times during C1 and C2 phases (obturation and lactation education) were 15.1 and 15.6 minutes. Volume of milk consumed during B1 and B2 feedings averaged 36.5 and 37 mL, compared with 67 mL and 76 mL during C1 and C2 phases. Growth as measured by height, weight gain, and weight for height during the study and the first 2 years of life compared favorably with that of children born without clefts. CONCLUSIONS: The combined use of a palatal obturator and lactation education reduced feeding time and increased volume intake and was associated with good growth. Mothers who had desired to breast-feed elected to use the obturator to support high-volume intake, decrease infant fatigue, and provide breast milk for nutrition.

Long-term treatment of severe dysarthria: a case study.

This case study describes the long-term treatment and changing symptoms in a single subject with dysarthria secondary to basilar artery thrombosis. Initially, the subject was anarthric. Treatment efforts thereafter were directed toward modifying speech respiration, velopharyngeal function, articulatory precision, speech intensity, and speech intelligibility. A variety of treatment and measurement techniques are illustrated. The behavioral change resulting from each of the treatments was small. However, when combined, these small gains in conjunction with some neurological recovery resulted in significantly improved communication and quality of life for this subject. Implications for management of similar subjects are discussed.
