Lateral border and scapular tip free flaps: Old school versus new school

xlomafota13 shared this article with you from Inoreader

Abstract

Free tissue transfer from the subscapular system provides a wide array of options for both soft tissue and bony reconstruction. When bone stock is required for head and neck reconstruction, both the lateral scapular border free flap (LSBFF), supplied by the circumflex scapular artery, and the scapular tip free flap (STFF), supplied by the angular artery, are excellent options. Issues with positioning had previously prevented the widespread use of these bony subscapular system flaps. However, through the use of a Spider Limb Positioner, current clinical practice patterns allow for two team approaches in both of these free flaps. The following pictorial essay compares and contrasts the specific positioning and harvesting technique used for both the LSBFF and STFF, while discussing the clinical advantages and drawbacks of each. Both the lateral border scapula and scapular tip free flaps provide excellent bone stock for head and neck reconstruction. By positioning with currently avail able technology, both of these free flaps can be harvested through a two team approach.

ABSTRACT

INTRODUCTION: Chiari I malformation (CMI) and hydrocephalus often coexist, with no clear understanding of the cause-and-effect relationship. In the absence of other associated etiologies, the traditional teaching has been to treat the hydrocephalus first, partly to minimize the risk of cerebrospinal fluid (CSF) leak from CMI decompression in the setting of elevated ICP. We describe a series of consecutive pediatric patients with CMI and hydrocephalus, the majority of whom were managed with posterior fossa decompression.

METHODS: A retrospective review was conducted on consecutive children who presented to the senior author with both hydrocephalus and CMI, with emphasis on rationale for and outcomes of surgical intervention, including the need for additional surgery.

RESULTS: There were 14 patients aged 2 weeks to 16 years (median 2 year s) who presented with Chiari I and hydrocephalus. Four of these underwent posterior fossa decompression without duraplasty (PFD) as first-line therapy (one of whom eventually required duraplasty), 7 had PFD with duraplasty (PFDD), 1 received a ventriculoperitoneal shunt (VPS), and two had endoscopic third ventriculostomy (ETV). Of the 11 who had PFD/D, 9 (90%) had significant symptom improvement/resolution, 7 (55%) showed decrease in ventricle size, and 1 (10%) required VPS placement for persistent hydrocephalus. Both ETV patients improved clinically, and 1 showed decrease in ventricle size. There were no pseudomeningoceles, infections, or neurological deficits. One CSF leak occurred after an ETV and was successfully treated with wound revision.

CONCLUSION: In patients with both CMI and hydrocephalus, treating the CMI first in an effort to avoid a shunt can be safe and effective. In this series, PFDD in the setting of hydrocephalus did not result in CSF leak or pseudomeningoce le. While limited by a small sample size, these data support a causative relationship between CMI and hydrocephalus.

ABSTRACT

Epidermoid cysts are generally benign lesions surrounded by squamous epithelium with cystic contents. The lining of the cysts produce keratin, which resemble a cheese-like material. They typically occur in the skin and mucous membranes and are congenital in origin; iatrogenic epidermoid cysts are rare. Epidermoid cysts are usually painless and asymptomatic, and the ir diagnosis is based on histological examination. This paper aims to present the case report of a 23-year-old patient with an iatrogenic epidermoid cyst that occurred following tracheostomy. The importance of preoperative radiological imaging in the diagnosis of epidermoid cysts is also highlighted.

SMS classification of inner ear malformations: our experience with implantation in type II anomalies

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2021 Oct 20. doi: 10.1007/s00405-021-07124-6. Online ahead of print.

ABSTRACT

PURPOSE: To study and analyse the radiological and surgical findings of 24 cochlear implantees with SMS type II cochleovestibular malformation and to compare their outcomes in terms of hearing and speech gains pre- and postoperatively.

METHODS: Retrospective analysis of cochlear implanted candidates over a period of 8 year 6 months from 3 institutions was undertaken and 24 patients suffering from prelingual profound congenital sensori-neural hearing loss along with the presence of SMS type II cochleovestibular malformation were studied. Preoperative radiology, surgical difficulties and complication, and postoperative hearing and speech outcomes up to a period of 2 years, using IT-MAIS and SIR scores were noted. Statistical comparison pre- and postimplantation was done using Wilcoxon signed rank test and a p value of < 0.05 was considered statistically significant.

RESULTS: In 24 cases, we encountered four cases of SMS type IIa malformation with a smaller modiolus, while the rest 20 were type SMS type IIb with partially defective modiolus. Intraoperatively, CSF leak was observed in 11 patients. Complete electrode insertion and good electrical response (NRT) was detected in all. No facial nerve anomaly was encountered. IT-MAIS and SIR scores increased from a preoperative mean of 5.6 and 1.16-34.56 and 3.88 after 2 years postsurgery, respectively and this difference was found to be statistically significant.

CONCLUSION: Our experience with SMS Type II malformations show promising and motivating results with less chances of complications. Proper evaluation and surgical planning preoperatively can lead to an uneventful surgery with good outcomes. A simple and uniform classification system of these anomalies is a must for appropriate prognostication and right decision making.

ABSTRACT

OBJECTIVES: The present study aimed to evaluate the effectiveness of a newly designed jaw-retraction exercise for strengthening the geniohyoid muscle and thus improving the anterior movement of the hyoid bone during swallowing.

BACKGROUND: Although previous studies suggest a relationship between anterior hyoid excursion and upper esophageal sphincter (UES) opening, there are currently no repor ts of physical exercises without the use of special equipment that can effectively improve this movement of the hyoid bone during swallowing.

MATERIALS AND METHODS: This before-after study included patients presenting to the authors' hospital with mild dysphagia (Level 5 on the Dysphagia Outcome and Severity Scale). The participants were instructed to perform a jaw-retraction exercise designed to strengthen the geniohyoid muscle. Each participant was instructed to perform two sets of the exercise daily for four weeks, with each set consisting of five repetitions. Before and after the four-week training period, videofluoroscopic swallowing studies were performed and later analysed.

RESULTS: Twenty-five patients with a median age of 77 were included. The median peak anterior hyoid position before and after exercise were 129.82 and 132.74 (%C2-C4 length), respectively, and this increase was found to be significant (P = .007). The median extent of UES opening before and afte r exercise were 8.6 and 9.3 (mm), respectively, and this increase was also found to be significant (P = .040).

CONCLUSION: Our findings demonstrate that the jaw-retraction exercise can effectively improve the anterior movement of the hyoid bone. This exercise may be effective in individuals with oral frailty when signs of swallowing disorders are observed.

BMC Endocr Disord. 2021 Oct 21;21(1):208. doi: 10.1186/s12902-021-00871-x.

ABSTRACT

BACKGROUND: To assess the gaps between the initial management of patients with differentiated thyroid cancer (DTC) in real clinical practice and the recommendations of the 2012 Chinese DTC guidelines.

METHODS: This multicenter, prospective study was conducted at nine tertiary hospitals across China. Eligible patients were those having intermediate or high-risk DTC after first-time thyroidectom y. During 1 year of follow-up, comprehensive medical records were collected and summarized using descriptive statistics.

RESULTS: Of 2013 patients, 1874 (93.1%) underwent standard surgery according to the guidelines (including total lobectomy plus isthmusectomy and total/near total thyroidectomy), and 1993 (99.0%) underwent lymph node dissection; only 56 (2.8%) had postoperative complications. Overall, 982/2013 patients (48.8%) received radioactive iodine (RAI) therapy after thyroidectomy. Of all enrolled patients, 61.4% achieved the target serum thyroid-stimulating hormone level, with a median time to target of 234.0 days (95% CI: 222.0-252.0). At 1 year of follow-up, proportions of patients with excellent response, incomplete structural response, biochemical incomplete response, and indeterminate response were 34.6, 11.2, 6.6, and 47.5%, respectively; recurrence or metastasis occurred in 27 patients (1.3%). During the overall study period, 209 patients (10.4%) had at least o ne adverse event: 65.1% of cases were mild, 24.9% moderate, and 10.1% severe.

CONCLUSIONS: This was the first large-scale prospective study of how patients with DTC in China are treated in actual practice. Initial DTC management is generally safe and adheres to the 2012 Chinese guidelines but could be improved, and the level of guideline adherence did not produce the anticipated treatment response at 1 year of follow-up.
