Ulnar forearm free flaps in head and neck reconstruction: systematic review of the literature and a case report.

OBJECTIVE: Under the assumption that the ulnar artery is the predominant blood supply to the hand, radial forearm free flaps (RFFF) generally have been preferred over ulnar forearm free flaps (UFFF) in head and neck reconstruction. The objective of this study is to create the first and only systematic review of the literature regarding UFFF in head and neck reconstruction, assessing the usage, morbidity, complications, and rationale of its use. METHODS: A systematic review of the literature was conducted using PubMed, including Mesh terms and manual searches. Articles not in English were excluded. RESULTS: Seventeen articles of the 80 articles identified by our search criteria met inclusion criteria; a total of 682 cases of UFFF were identified, including our patient case. Fifty-five percent of the cases involved use of the Allen's test. Mean flap size was 6.1 × 10.5 cm. Of the 432 cases reporting flap survival, 14 (3.2%) flap losses were reported, 13 total (3.0%), and one partial (0.2%). The UFFF was preferred to the RFFF due to decreased hirsutism (61%), better cosmetic outcomes (91%), and better post-operative hand function with reduced donor site morbidity (73%). For the case report, an UFFF was used successfully for lid reconstruction and resurfacing in a 72-year-old man who presented with late ectropion and exposure keratopathy following maxillary resection for leiomyosarcoma. CONCLUSIONS: This is the first and only systematic review of the literature to date of UFFF in head and neck reconstruction. Our review demonstrates that the UFFF rarely results in flap loss, donor site morbidity, or hand ischemia, instead providing enhanced outcomes. With its many surgeon-perceived advantages and minimal morbidity, the UFFF may become a preferred forearm flap for head and neck reconstruction.

Perioperative care in functional endoscopic sinus surgery: a survey study.

BACKGROUND: Functional endoscopic sinus surgery (FESS) is largely viewed as the standard of care in the treatment of chronic rhinosinusitis (CRS) refractory to medical treatment. While there is an understanding regarding the importance of some form of routine postoperative FESS care, no consensus currently exists regarding what the specific management routine should include. The authors of this survey study did not intend to examine the efficacy of such treatment protocols, but rather to determine and report on the current practice patterns of perioperative FESS care among otolaryngologists. METHODS: This survey study was designed in accordance with and approved by our institutional review board. The online-based survey was designed using the online product SurveyMonkey®. A total of 859 otolaryngologists were identified and email addresses were obtained from the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) website directory. Responses were collected anonymously. RESULTS: Our survey response rate was 32%. Multiple parameters of the otolaryngologists' perioperative care were collected. Among the data, some consistent patterns emerged: 93.2% of respondents use nasal saline irrigations postoperatively; 86.8% of otolaryngologists surveyed prescribe antibiotics in the immediate postoperative period; and office-based endoscopic sinus debridements are performed by a majority (87.9%) of those surveyed. CONCLUSION: This survey study demonstrates that current practices in perioperative FESS care can vary widely among otolaryngologists, and are not uniformly based on evidence-based outcomes research. Despite the lack of absolutes regarding the specific perioperative care in FESS, practice patterns emerge from the data regarding typical perioperative management among current otolaryngologists.

Increased medial temporal lobe activation during the passive viewing of emotional and neutral facial expressions in schizophrenia.

INTRODUCTION: Patients with schizophrenia show deficits in facial affect and facial identity recognition and exhibit structural and neurophysiological abnormalities in brain regions known to mediate these processes. Functional neuroimaging studies of neural responses to emotional facial expressions in schizophrenia have reported both increases and decreases in medial temporal lobe (MTL) activity in schizophrenia. Some of this variability may be related to the tasks performed and the baseline conditions used. Here we tested whether MTL responses to human faces in schizophrenia are abnormal when unconstrained by a cognitive task and measured relative to a low-level baseline (fixation) condition. METHODS: 15 patients with schizophrenia and 16 healthy control subjects underwent functional magnetic resonance imaging (fMRI) while passively viewing human faces displaying fearful, happy, and neutral emotional expressions. RESULTS: Relative to control subjects, the patients demonstrated (1) significantly greater activation of the left hippocampus while viewing all three facial expressions and (2) increased right amygdala activation during the initial presentation of fearful and neutral facial expressions. CONCLUSIONS: In schizophrenia, hippocampal and amygdala activity is elevated during the passive viewing of human faces.
