Synovial sarcoma is a high-grade soft tissue sarcoma that rarely arises in the head and neck region. It affects the parapharyngeal space and the hypopharynx most commonly and it has different presentations based on the affected site. In extremely rare occasions, it involves the hard palate such as in our case where a 24-year-old female patient presented with a mass lesion involving the left hard palate, which was identified clinically and by imaging studies. The histopathological assessment confirmed that it was a monophasic synovial sarcoma which was also confirmed with further molecular studies. The patient underwent surgical excision and postoperative radiotherapy. Her close follow up over a 6-year period that followed her curative treatment has demonstrated no evidence of disease recurrence or distant metastasis. Surgical excision is the mainstay of treatment for synovial sarcoma and adjuvant radiotherapy is advised. Long-term follow up is recommended because of the remote possibility of late recurrence of the tumor.
Objective: To determine the effect of cochlear coverage on audiological and speech parameters in patients with cochlear implants. Previous work has investigated the effect of tailoring electrode size to a cochlear implant recipient's individual cochlear duct length (CDL). However, no clear relationship has been found between speech development and the extent of electrode insertion, and the benefits of apical stimulation are not yet clear. Methodology: In this retrospective study, we assessed the effect of cochlear coverage on audiological and speech performance. Participants were prelingually deaf children who received cochlear implants between June 2013 and December 2014 under the care of a single cochlear implant surgeon. Cochlear coverage was estimated for each ear according to electrode type, depth of insertion, and the number of active electrodes. Electrode type and length were determined by the individual's CDL, measured by computed tomography (CT), and full insertion was documented intraoperatively. The number of active electrodes was recorded using intraoperative audiological response telemetry. Audiological assessments were obtained 6 months and 1 year postoperatively. Results of the categories of auditory performance-II and speech intelligibility rating scales were obtained after 3 years. Patients were divided into two groups based on their cochlear coverage and their audiological and speech outcomes were compared. Results: Of the 97 children recruited, 47 were girls. Temporal bone CT scans showed the right and left mean CDLs among girls were 27.7 and 27.9 mm, respectively, and 29.2 mm for both ears in boys. For each sex, the right and left CDLs did not differ significantly (p = 0.07). Twenty patients were lost to follow-up, leaving 77 patients (120 ears), which were divided into groups according to cochlear coverage (complete vs. incomplete). Significant between-group differences were not found in assessments of audiology, categories of auditory performances, or speech intelligibility ratings after 3 years. Conclusion: Audiological parameters do not differ according to the degree of cochlear coverage, specifically for low-frequency tones. Speech parameters are also comparable. Therefore, complete cochlear coverage does not appear to provide significant benefit over incomplete coverage for prelingually deaf cochlear implant recipients.
BACKGROUND: Facial nerve weakness is the most common and most concerning complication after parotidectomy. Risk factors for this complication following surgery for benign diseases remain controversial. OBJECTIVE: Review the frequency and prognosis of facial nerve weakness after parotidectomy and analyze potential risk factors. DESIGN: Retrospective review of medical records. SETTINGS: Two tertiary care centers. PATIENTS AND METHODS: We included all parotidectomies performed for benign diseases from January 2006 to December 2018. Details about the development and recovery of postoperative facial weakness were recorded. Patient, disease and surgery-related variables were analyzed using bivariate and multivariate analyses to identify risk factors. MAIN OUTCOME MEASURES: Frequency, recovery rates and risk factors for facial nerve weakness SAMPLE SIZE: 191 parotidectomies, 183 patients, 61 patients with facial weakness. RESULTS: The frequency of postoperative facial weakness was 31.9% (61/191 parotidectomies). Among patients with temporary weakness, 90% regained normal facial movement within 6 months. Steroid therapy was not associated with a faster recovery. Postoperative weakness was not associated with age, diabetes, smoking, disease location, use of an intraoperative facial nerve monitor or direction of facial nerve dissection. Risk factors for temporary weakness were total parotidectomy and surgical specimens larger than 60 cubic centimeters. Revision surgery was the only identified risk factor for permanent weakness. CONCLUSION: Larger parotid resections increase the risk of temporary facial nerve weakness while permanent weakness is mainly influenced by previous surgeries. LIMITATIONS: Retrospective nature, underpowered sample size, selection bias associated with tertiary care cases. CONFLICT OF INTEREST: None.
BACKGROUND: Thyroid malignancy, the most diagnosed cancer of the endocrine system, represents 2% of all malignancies worldwide. The increasing incidence of thyroid cancer has been linked to the increasing sensitivity of modern diagnostic methods which overdiagnosis small thyroid tumors.OBJECTIVES: Assess the distribution and trends in thyroid cancer among thyroidectomy patients.DESIGN: Descriptive, based on medical record review.SETTINGS: Two tertiary care centers in Riyadh.PATIENTS AND METHODS: We included patients who underwent thyroid surgery from January 1, 2004 to December 31, 2016 who ranged in age from 9–90 years regardless of initial diagnosis.MAIN OUTCOME MEASURES: Distribution of thyroid carcinomas by type, age and sex and trends over the time period.SAMPLE SIZE: 979 patients.RESULTS: Of 979 patients, 84.5% were <55 years old, with the majority being female. Thyroid malignancy ranked second to benign tumors, and the most common type of thyroid cancer was papillary thyroid carcinoma (91% of malignant tumors), followed by follicular thyroid cancer (4.7% of malignant tumors). After thyroid microcarcinomas were isolated from the sample and studied separately, we found the overall trend for thyroid cancer to be stable, and that the annual increases in rates were due to increased diagnosis of thyroid microcarcinoma in the period from 2010 to 2016.CONCLUSION: Our study shows that increases in thyroid cancers may be attributed to a rise in the rates of diagnosis of thyroid microcarcinomas.LIMITATIONS: The main limitation is the retrospective nature of this design. Also, a multicenter collaboration would prove beneficial in evaluating the trends of thyroid cancer in Saudi Arabia on a much larger scale.CONFLICT OF INTEREST: None.
Objectives: To address the factors affecting recurrence after endoscopic surgical repairs of spontaneous cerebrospinal fluid leak, specifically the influence of using lumbar drains. Methods: This study involved a retrospective data analysis, including a chart review of all spontaneous cerebrospinal fluid (CSF) leak cases who underwent endoscopic anterior skull base repair from 2012-2017 in King Fahad Medical City, Riyadh, Kingdom of Saudi Arabia. Original Articles Results: Thirteen patients with spontaneous CSF leaks were identified and evaluated. The majority were females (92.3%) with an average body mass index of 34.9. All patients underwent endoscopic repair with intra-operative lumbar drain placement. Patients continued having post-operative lumbar drain for an average of 6.4 days. Four patients (30.8%) developed recurrence; however, only one of those had a documented high opening pressure. Conclusion: Spontaneous CSF leak repairs are at a higher failure risk and may have an underlying pathology involving CSF circulation. The use of lumbar drains and intracranial pressure lowering agents are controversial and seems to be reserved only for high risk patients; however, the higher risk of recurrence in this group may be better managed by proper pre-operative evaluation and selective, patientspecific management protocols.
