Indications and Outcomes of Parotidectomy in Saudi Children: Experience From Two Tertiary Centers.

Introduction Children can present with a wide variety of parotid diseases. However, most of them do not require surgical treatment. The indications of parotid surgery in children may differ from those in adults. In this study, we aim to review the indications and outcomes of parotidectomy in our pediatric population. Methods Retrospective review of the medical records of patients who underwent parotid surgery at age <18 years in two tertiary centers over a 14-year period. Results A total of 18 parotidectomies were performed on 18 patients with a mean age of 13.5 years. All patients presented with a parotid mass. The most common procedure was superficial parotidectomy followed by total parotidectomy. Ten patients were diagnosed with a benign parotid disease (55.6%). The most common benign disease was pleomorphic adenoma. There were eight cases of parotid malignancy constituting 44.4% of all patients and 57% of patients presenting in the age range of 12-17 years. Mucoepidermoid carcinoma was the most common malignancy (six patients). Fine needle aspiration biopsy was performed in 12 children with a sensitivity, specificity, and overall accuracy of 62.5%, 50%, and 58.6%, respectively. The most common complication was temporary facial weakness (33.3%) which resolved in a mean time of 2.5 months. No disease recurrences were identified. Conclusions Parotidectomy is uncommon in the pediatric age group. Children with a solid parotid tumor have a higher risk of parotid malignancy when compared to adults. A parotid mass presenting in the second decade of life is more likely to be malignant than benign.

Seasonal variations in serum levels of vitamin D and other biochemical markers among KSA patients prior to thyroid surgery.

OBJECTIVES: Serum levels of vitamin D can vary between seasons, which may affect serum calcium levels in post-thyroidectomy patients. This study aimed to determine seasonal variations in serum levels of vitamin D and other biochemical markers in patients prior to thyroid surgery in a KSA hospital. METHODS: In this study, we analysed the data of 685 post-thyroidectomy patients. The preoperative laboratory values of all patients were collected, and the patients were categorized into groups based on the month when the surgical procedure was performed as follows: cold (November-February) and warm/hot groups (March-October). RESULTS: Serum vitamin D levels were deficient in 70% of the patients, insufficient in 18%, and optimal in 12%. The mean age of patients in the deficient group was significantly lower than that in the optimal group. There were significantly more patients who had vitamin D deficiency during the cold season than during the warm/hot season (p = 0.024). Serum vitamin D levels did not vary between seasons (p = 0.836); however, the preoperative magnesium and thyroid stimulating hormone (TSH) levels were significantly higher during the warm/hot season than during the cold season (p = 0.039 and p < 0.001, respectively). Preoperative calcium level was not significantly different between the cold and warm/hot months (p = 0.282). CONCLUSION: This study suggests a non-significant seasonal fluctuation in serum levels of vitamin D with insignificant variation in serum calcium levels during cold and warm/hot seasons. The findings necessitate a careful review of the patients' biochemical status prior to surgery. Future prospective longitudinal studies are needed to confirm this variability.

Factors associated with facial weakness following surgery for benign parotid disease: a retrospective multicenter study.

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.

Translation and cultural adaptation of an Arabic version of the patient scar assessment scale for thyroidectomy patients.

OBJECTIVES: To translate and validate an Arabic version of the patient scar assessment scale (PSAS). The cosmetic appearance of a thyroidectomy scar can critically influence a patient's self-esteem. Moreover, scar evaluation tools are necessary for an evidence-based approach to scar management. METHODS: This  quantitative, observational, cross-sectional study was conducted by administering an Arabic-translated version of the PSAS. The translation process included a forward translation into Arabic by 3 fluently bilingual otolaryngologists, a back-translation into English, and a comparison with the original items. The questionnaires were distributed to patients who underwent thyroidectomies. We included patients who underwent surgery at least 2 months previously. RESULTS: A total of 50 patients were included in this research. The internal consistency was 0.89, with a 95% confidence interval (CI) of 0.88-0.90. The score distributions showed high correlations for all items. The Arabic-translated PSAS showed good test-retest reliability, and the Pearson correlation coefficient between the test and retest administrations was 0.84 (p<0.001). With a possible range of 6-60 points, the standard error of the mean was 5.14, and the minimal detectable change was 14.2. CONCLUSION: This Arabic version of the PSAS was reliable for use in Arabic-speaking communities. It will allow for comparisons between the results of investigations conducted in different countries, which aids in the exchange of information within the international scientific community.
