RESUMO
PURPOSE: Historically, free tissue transfer has been reserved for advanced stage osteoradionecrosis (ORN) of the jaw with pathologic fracture or cutaneous fistula. The purpose of this study was to evaluate if in patients with recalcitrant intermediate stage ORN, would mandibular debridement in combination with vascularized soft tissue coverage result in durable symptom and disease resolution. PATIENTS AND METHODS: A retrospective cohort study of patients with mandibular ORN was performed comparing a mandibular preserving approach with a fasciocutaneous forearm flap for progressive treatment-resistant intermediate stage ORN to mandibulectomy and vascularized bone flap (VBF) reconstruction for advanced stage ORN. The primary outcome was ORN resolution. RESULTS: The sample was composed of 35 patients. One-hundred percent of patients undergoing a mandibular preserving approach experienced ORN resolution compared with 83.3% in the segmental mandibulectomy and VBF reconstruction group (P = .28). Patients in the mandibular preservation group experienced a shorter hospitalization (6 vs 9 days; P = .07), decreased length of surgery (384.9 vs 406.3 minutes; P = .01), and less delayed healing requiring local wound care (9.1 vs 45.8% of patients; P = .06). CONCLUSIONS: A mandibular preserving approach is successful at arresting intermediate stage ORN and is associated with a decreased operative time, a shorter hospitalization, and less need for prolonged wound care when compared with VBF reconstruction for advanced stage ORN.

Patients undergoing partial or total rhinectomy surgeries are left with a lifelong facial defect that poses psychosocial and functional challenges. The extended postoperative healing period after rhinectomy can delay the timely restoration of a patient's nose by definitive prosthesis when conventional impression methods are used. The treatment workflow for fabricating a custom esthetic nasal bandage with the use of digital technology is introduced to avoid the conventional preoperative impression, as well as to allow for immediate delivery at the postoperative follow-up visit.

Patients undergoing partial rhinectomy with limited size may have the major portion of the nasal structure preserved. However, the fibrosis or scar formation after the surgery may cause distortion of remaining tissues, followed by nasal airway obstruction. By physically expanding an affected nostril during the impression and using digital technology to design a custom flexible internal nasal dilator, embedded in the medical grade silicone during processing, a partial nasal prosthesis with airway-maintaining purpose can be fabricated to improve quality of life both esthetically and functionally.

The basic objective in prosthetic restoration of confluent maxillary and orbital defects is to achieve a comfortable, cosmetically acceptable prosthesis that restores speech, deglutition, and mastication. It is a challenging task complicated by the size and shape of the defects. The maxillary obturator prosthesis often satisfies the objective of adequate deglutition; however, orbital defects that are not obturated in the medial, septal, or posterior walls allow air to escape, negatively impacting phonation. This article describes a technique to achieve favorable prosthetic rehabilitation in a patient with a maxillectomy and ipsilateral orbital exenteration. The prosthetic components include maxillary obturator, orbital conformer, and orbital prosthesis connected using rigid magnetic attachments.

Orthognathic surgery is generally a safe and predictable procedure. Major postoperative complications are rare and often non-life threatening. An example of a rare complication associated with the LeFort I osteotomy is avascular necrosis of the maxilla (ANM). While cases of ANM have been described in the literature, the majority involves only a portion or segment of the maxillary complex and is commonly treated with conservative measures such as strict oral hygiene, hyperbaric oxygen therapy and local debridement. Occasionally, larger segments of osteonecrosis may require extensive reconstruction such as bone grafting with local soft tissue flaps. Here, we present a patient that underwent a single-stage microvascular free tissue reconstruction with concomitant placement of dental implants and a patient-specific implant (PSI) for post-orthognathic ANM.
RESUMO
OBJECTIVE: To investigate the impact of reminder-focused positive psychiatry (RFPP) on attention-deficit/hyperactive disorder (ADHD) and posttraumatic stress disorder (PTSD) symptoms, vascular-function, inflammation and well-being of adolescents with comorbid ADHD and PTSD. METHODS: After obtaining informed-consent, 11 adolescents were randomized to RFPP (n = 5) or trauma-focused cognitive-behavioral therapy (TF-CBT) (n = 6). Eight participants (RFPP: n = 4, TF-CBT: n = 4) completed the twice-weekly intervention for a 6-week trial. The RFPP intervention was inclusive of positive psychiatry interventions on (1) traumatic reminders and (2) avoidance and negative cognition. Vascular function measured as temperature rebound, C-reactive protein, homocysteine, ADHD Swanson, Nolan, and Pelham (SNAP) Questionnaire, Clinician-Administered PTSD Scale for DSM-5-Child/Adolescent Version (CAPS-CA), and neuropsychiatric-measures were measured at baseline and 6 weeks. Subjects were followed for 12 months. The study was conducted from September 2016 to June 2018. RESULTS: A significant improvement in CAPS-CA, SNAP scores, and vascular function of both RFPP and TF-CBT groups was noted at follow-up, but was more-robust in the RFPP group (P < .05). At the sixth week, a significant increase in PERMA, gratitude, resilience, and Posttraumatic Growth Inventory scores and a significant decrease in homocysteine and C-reactive protein levels in the RFPP group, but not the TF-CBT group, were noted (P < .05). At 12-month follow-up, there was no psychiatry hospitalization or suicide ideation reported in either group. A continuation of significant improvement in CAPS-CA and SNAP scores in both groups was noted but was more robust in the RFPP group (P < .05). Similarly, a continuation of significant increase in PERMA, gratitude, resilience and Posttraumatic Growth Inventory scores was noted in the RFPP group but not in the TF-CBT group (P < .05). CONCLUSIONS: RFPP is associated with improvement in core PTSD and ADHD symptoms, decrease in inflammation, and increase in well-being, vascular function, and posttraumatic growth, as well as a favorable long-term clinical outcome. This finding highlights the importance of the dual role of RFPP in addressing vulnerability symptoms as well as enhancing well-being in youth with comorbid ADHD and PTSD. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT04336072.

OBJECTIVE: The purpose of this study was to determine dose delivered to individual mandibular tooth-bearing regions during adjuvant intensity-modulated radiotherapy for laryngeal cancers. STUDY DESIGN: Twenty patients with laryngeal cancer treated with intensity-modulated radiotherapy were included. Individual mandibular tooth-borne areas were manually contoured. Average doses were calculated for individual teeth. RESULTS: Doses to individual teeth increased with more posterior location. Highest dose was observed for third molar (M3) (43.1 Gy; P < .001). Doses to molars and premolars correlated with T- and N-stage (P = .007; P < .001, respectively). For ipsilateral nodal disease, there was no difference between the doses to ipsilateral teeth and contralateral teeth. Only in N2 c tumors, dose was above our threshold for extraction for M3 only (51.5 Gy). CONCLUSIONS: T- and N-stage drive dose to individual mandibular tooth-borne areas. With the exception of the posterior molars, particularly in node-positive patients, radiation exposure falls below the threshold reported for pre-RT tooth extractions (50 Gy). We concluded that a more conservative approach to prophylactic tooth extraction with a greater emphasis on dental management may be warranted for the prevention of osteoradionecrosis in patients with laryngeal cancer receiving adjuvant RT.

OBJECTIVE: Several studies have reported that ethnic differences influence psychiatric diagnoses. Some previous studies reported that African Americans and Hispanics are diagnosed with schizophrenia spectrum disorders more frequently than Caucasians, and that Caucasians are more likely to be diagnosed with affective disorders than other ethnic groups. We sought to identify associations between sociodemographic factors and psychiatric diagnosis. METHODS: We retrospectively examined the medical records of all psychiatric inpatients (ages over 18 years) treated at Kern county mental hospital (n=2,051) between July 2003 and March 2007 for demographic, clinical information, and discharge diagnoses. RESULTS: African American and Hispanic males were more frequently diagnosed with schizophrenia spectrum disorders than Caucasians, whereas Caucasian females were more frequently diagnosed with affective disorders than females in the other ethnic groups, suggesting that patient ethnicity and gender may influence clinical diagnoses. Demographic variables, that is, a lower education, failure of marriage, homelessness, and low quality insurance, were found to be significantly associated with a diagnosis of schizophrenia spectrum disorders after adjusting for clinical variables. And, the presence of a family psychiatric history, failure of marriage, not-homelessness, and quality insurance were found to be associated with a diagnosis of affective disorders. CONCLUSION: Our results show that these demographic factors, including ethnicity, have effects on diagnoses in psychiatric inpatients. Furthermore, these variables may help prediction of psychiatric diagnoses.
