RESUMO
Importance Free tissue transfer for reconstruction of the head and neck requires complicated repair of complex anatomy. The posterior tibial flap is a free tissue flap that has viability and versatility to be used for complex reconstructions that is not offered by other free flaps. OBJECTIVE: The posterior tibial artery flap is a perforator flap which is found between the flexor digitorum longus and the soleus. It has been described as both a pedicled flap for lower extremity reconstruction as well as a free flap, including for head and neck reconstruction. Limited data exists on the subject in the English literature. The objective of this study is to present our experience with the flap in the head and neck. DESIGN: Retrospective review of cases from a single institution between October 2019 and May 2023. Primary indications included patients whose defects were felt to be larger than a conventional radial forearm free flap that were not well served by the anterolateral thigh flap, either because of body habitus or room for the associated muscle. SETTING: Tertiary academic hospital system performing free tissue transfer reconstruction of within the head and neck. RESULTS: Fifteen patients underwent posterior tibial artery free flap during the study period. Indications for flap reconstruction included oral cavity, tongue, oropharynx and skin of the scalp and forehead. Flap size ranged from 24cm2 to 143cm2. Only one flap failure was observed. Flap harvest time was universally under forty-six minutes, and as little as thirty-two. CONCLUSION: The posterior tibial artery flap is a useful option in head and neck reconstruction. It provides an intermediary in size and bulk between the radial forearm and the anterolateral thigh flap. Additionally, it provides a straightforward harvest with minimal donor site morbidity.

We present a case of two siblings born to nonconsanguineous parents that presented with hypotonia, respiratory insufficiency, and auditory neuropathy spectrum disorder (ANSD) correlated with NFASC (MIM: 609145) and the homozygous loss of function variant p.P924RfsX35. This appears to be the first two reported cases of NFASC correlated with ANSD. NFASC encodes for neurofascin which plays an important role in the formation, function and maintenance of axon initial segments and nodes of Ranvier. Due to the rarity of this gene variation, reports are sparse in the literature leading to delays in diagnosis which can impact patient's language acquisition and spoken language skills.

BACKGROUND: Patients are increasingly turning to the internet for health education. Due to the complex pathophysiology, clinic-diagnostic profile, and management spectrum of pituitary tumors, an evaluation of the readability of printed online education materials (POEMs) regarding this entity is warranted. OBJECTIVE: (1) To apply established readability assessment tools to internet search results on the topic of pituitary tumors. (2) To identify sources of complexity in order to guide the creation POEMs that are in line with the reading level of the target audience.Methodology: After independent, neutral internet search for the phrase "pituitary tumor," the first 100 results were subjected to inclusion criteria matching. Analysis was performed using 5 readability assessment tools including Flesch Reading Ease (FRE), Flesch-Kincaid Grade Level (FKGL), Gunning-Fog Score (GFS), Coleman-Liau Index (CLI), and Simple Measure of Gobbledygook (SMOG). RESULTS: A total of 82 websites met inclusion criteria. All websites were found to be at a higher reading level (P < .01) than the United States Department of Health and Human Services (USDHHS) recommended sixth-grade level. Mean readability scores were as follows: FRE, 38.79; FKGL, 11.27; GFS, 12.83; CLI, 17.31; SMOG, 12.12. Intergroup comparison between FKGL, GFS, CLI, and SMOG yielded that CLI was significantly higher (P < .03). No significant differences in readability were noted between academic and other websites. CONCLUSION: There is a significant misalignment between the reading level of patients and the readability of pituitary tumor POEMs. This may lead patients to misconceive their diagnoses, management options, and prognosis.
