Current Strategies for Treatment of Mandibular Fractures With Plate Osteosynthesis: A European Prospective Study.

PURPOSE: The training and preferences of surgeons influence the type of surgical treatment for mandibular fractures. This multicentre prospective study analyzed the current treatment strategies and outcomes for mandibular fractures with open reduction and internal fixation (ORIF). MATERIAL AND METHODS: This prospective study included patients aged ≥16 years who underwent ORIF for mandibular fractures in 12 European maxillofacial centers. Age, sex, pretrauma dental status, fracture cause, site and type, associated facial fractures, surgical approach, plate number and thickness (≤1.4 or ≥1.5 mm), duration of postoperative maxillomandibular fixation, occlusal and infective complications at 6 weeks and 3 months, and revision surgeries were recorded. RESULTS: Between May 1, 2021 and April 30, 2022, 425 patients (194 single, 182 double, and 49 triple mandibular fractures) underwent ORIF for 1 or more fractures. Rigid osteosynthesis was performed for 74% of fractures and was significantly associated with displaced ( P =0.01) and comminuted ( P =0.03) fractures and with the number of nonsurgically treated fracture sites ( P =0.002). The angle was the only site associated with nonrigid osteosynthesis ( P <0.001). Malocclusions (5.6%) and infective complications (5.4%) were not associated with osteosynthesis type. CONCLUSION: Rigid osteosynthesis was the most frequently performed treatment at all fracture sites, except the mandibular angle, and was significantly associated with displaced and comminuted fractures and the number of nonsurgically treated fracture sites. No significant differences were observed regarding postoperative malocclusion or infections among osteosynthesis types.

Manual versus rigid intraoperative maxillo-mandibular fixation in the surgical management of mandibular fractures: A European prospective analysis.

PURPOSE: Intraoperative stabilisation of bony fragments with maxillo-mandibular fixation (MMF) is an essential step in the surgical treatment of mandibular fractures that are treated with open reduction and internal fixation (ORIF). The MMF can be performed with or without wire-based methods, rigid or manual MMF, respectively. The aim of this study was to compare the use of manual versus rigid MMF, in terms of occlusal outcomes and infective complications. MATERIALS AND METHODS: This multi-centric prospective study involved 12 European maxillofacial centres and included adult patients (age ≥16 years) with mandibular fractures treated with ORIF. The following data were collected: age, gender, pre-trauma dental status (dentate or partially dentate), cause of injury, fracture site, associated facial fractures, surgical approach, modality of intraoperative MMF (manual or rigid), outcome (minor/major malocclusions and infective complications) and revision surgeries. The main outcome was malocclusion at 6 weeks after surgery. RESULTS: Between May 1, 2021 and April 30, 2022, 319 patients-257 males and 62 females (median age, 28 years)-with mandibular fractures (185 single, 116 double and 18 triple fractures) were hospitalised and treated with ORIF. Intraoperative MMF was performed manually on 112 (35%) patients and with rigid MMF on 207 (65%) patients. The study variables did not differ significantly between the two groups, except for age. Minor occlusion disturbances were observed in 4 (3.6%) patients in the manual MMF group and in 10 (4.8%) patients in the rigid MMF group (p > .05). In the rigid MMF group, only one case of major malocclusion required a revision surgery. Infective complications involved 3.6% and 5.8% of patients in the manual and rigid MMF group, respectively (p > .05). CONCLUSION: Intraoperative MMF was performed manually in nearly one third of the patients, with wide variability among the centres and no difference observed in terms of number, site and displacement of fractures. No significant difference was found in terms of postoperative malocclusion among patients treated with manual or rigid MMF. This suggests that both techniques were equally effective in providing intraoperative MMF.

Does the SARS-CoV-2 pandemic really increase the frequency of peripheral facial palsy?

PURPOSE: Publications about increased number of peripheral facial paralysis in the COVID-19 pandemic emerged in the literature. However, these studies comprised of an estimate rather than a broad analysis of exact numbers. In this study, we planned to investigate whether the pandemic really resulted in an increase in facial paralysis cases admitted to the hospital by evaluating the cases who applied to our hospital due to facial paralysis in the COVID-19 pandemic year and in the previous 4 years. MATERIALS AND METHODS: Patients who applied to our hospital due to facial paralysis between March 2016-February 2017 (Group 1), between March 2017-February 2018 (Group 2), between March 2018-February 2019 (Group 3), between March 2019-February 2020 (Group 4), and between March 2020-February 2021 (Group 5) were investigated and detailed data were noted. RESULTS: 156, 164, 149, 172 and 157 patients were admitted to the hospital due to peripheral facial paralysis in Group 1, 2, 3, 4, and 5, respectively. Of these patients, 155, 164, 145, 169, and 153 were Bell's palsy, respectively. SARS-CoV-2 RT-PCR test was positive in only 2 of the 153 patients who were diagnosed in the year of the pandemic. CONCLUSIONS: This study showed that the number of peripheral facial paralysis detected during the COVID-19 pandemic was similar to previous years. Very few number of positive SARS-CoV-2 RT-PCR test results may have been found incidentally in Bell's palsy patients. Theses stating that SARS-CoV-2 causes peripheral facial paralysis should be supported by laboratory studies and postmortem research.

European multicenter prospective analysis of the use of maxillomandibular fixation for mandibular fractures treated with open reduction and internal fixation.

INTRODUCTION: The goal of mandibular fracture treatment is to restore static and dynamic occlusal functions. Open reduction and internal fixation (ORIF) of these fractures can be associated with an intraoperative and/or postoperative maxillo-mandibular fixation (MMF). The aim of this study was to analyse the use of perioperative MMF and its effects on occlusal outcomes in the management of mandibular fractures. MATERIAL AND METHODS: This multicentric prospective study included adult patients with mandibular fractures treated with ORIF. The following data were collected: age, gender, pre-trauma dental status (dentate, partially dentate), cause of injury, fracture site, associated facial fractures, surgical approach, type of ORIF (rigid, non-rigid or mixed), thickness and number of plates, modality of intraoperative MMF (arch bars, self-tapping and self-drilling screws [STSDSs], manual, other) and duration of postoperative MMF. The primary outcome was malocclusion at 6 weeks and 3 months. Statistical analyses were performed with Fisher's exact test or chi-square test, as appropriate. RESULTS: Between 1 May 2021 and 30 April 2022, 336 patients, 264 males and 72 females (median age, 28 years) with mandibular fractures (194 single, 124 double and 18 triple fractures) were hospitalized. Intraoperative MMF was performed in all patients. Osteosynthesis was rigid in 75% of single fractures, and rigid or mixed in 85% and 100% of double and triple fractures, respectively. Excluding patients who underwent manual reduction, postoperative MMF (median duration, 3 weeks) was performed in 140 (64%) patients, without differences by type or number of fractures (p > 0.05). No significant difference was found in the incidence of malocclusion in patients with postoperative MMF (5%, 95% confidence interval [CI], 2-10%) compared to those without (4%; 95% IC, 1-11%) (p > 0.05). CONCLUSION: Postoperative MMF was performed in more than half of the patients despite adequate fracture osteosynthesis, with wide variability amongst centers. No evidence of a reduction in the incidence of postoperative malocclusion in patients treated with postoperative MMF was found.

Auricular anthropometric growth study in individuals with trisomy 21.

In this study, we aimed to measure the auricle dimensions of individuals with Down syndrome, which are known to have different anomalies, and to evaluate the auricle development from birth. A total of 18 groups were formed, consisting of individuals from the neonatal period to age 18 years. Additionally, individuals older than 18 years old were added as an adult group (19 groups in total). Each group has 20 individuals. Measurements were taken in six dimensions. These measurements included the distance from the suprahelix to infralobule (A), helix to tragus (B), antihelix to tragus (C), conchal attachment point to tragus (D), suprahelix to the mastoid, (E), and helix to mastoid at the tragus level (F). It was found that the A value reached adult size at the age of 13 in both boys and girls. For the B, D, and E values, it was found that sizes reach the adult size at the ages of 5, 8, and 7 for both genders, respectively. The C value reached adult size in boys by age 1, but there was no significant difference for girls between the adult and any age value. It was found that the F value reached the adult size at age of 4 for boys and 5 for girls. These results may be a guide for individuals with Down syndrome in terms of the surgical timing of the auricle if necessary.

Laparoscopic primary repair of ventral hernias: early results of a new technique.

Epigastric, umbilical, incisional, parastomal, and trocar site hernias are all classified as "ventral" hernias, which constitute a great portion of the surgery in a general surgical practice, and debate still continues regarding the optimal surgical strategy to correct these anatomical defects. Although repairing these hernias using a synthetic material, whether placed open or laparoscopically, has gained wide popularity, there are some situations where the use of a mesh is either unnecessary or contraindicated. This article presents the cases of 10 patients with some kind of ventral hernia which were all repaired laparoscopically with a primary suturing technique.

Effects of thyroid hormone on the adaptation in short bowel syndrome.

BACKGROUND: Thyroid hormone acts on structural and functional maturation of the mammalian small intestine, mitochondrial pathways, and several protein-gene interactions. Therefore, it is one of the most important regulators of intestinal epithelial differentiation. The aim of the study was to evaluate the effects of thyroid hormone on the adaptation in an experimental model of short bowel syndrome. METHODS: Rats were divided into three groups: sham (bowel transection and anastomosis), short bowel syndrome-saline (75% bowel resection and anastomosis), and short bowel syndrome-thyroid hormone (75% bowel resection and anastomosis, and was administered triiodothyronine). The evaluation of adaptation parameters, histopathological and biochemical analysis were performed in all groups. RESULTS: Triiodothyronine treatment resulted in a significant increase in adaptation parameters, villus height-crypt depth, and enterocyte proliferation, whereas significant decrease was seen in apoptotic index in jejunum. Enterocyte proliferation and most of the adaptation parameters changed significantly in ileum following the treatment with triiodothyronine as in jejunum. The changes in ileal villus height-crypt depth and apoptotic index were not statistically significant. Serum levels of free triiodothyronine were lower in the short bowel syndrome-saline group. CONCLUSIONS: Our results suggest that thyroid hormone treatment in the hypothyroid phase of SBS enhances intestinal adaptive response.

The timing of laparoscopic cholecystectomy after endoscopic retrograde cholangiopancreaticography in cholelithiasis coexisting with choledocholithiasis.

BACKGROUND: An accepted treatment strategy for cholelithiasis with secondary choledocholithiasis is the laparoscopic cholecystectomy (LC) following endoscopic retrograde cholangiopancreaticography (ERCP). Although early cholecystectomy is advised, there is no consensus about the time interval between LC and ERCP. The aim of this study is to evaluate the effects of the time interval between ERCP and ERCP on operation outcomes. METHODS: Patients with cholelithiasis and a risk of choledocholithiasis underwent ERCP. Patients were grouped as those operated on between 24 and 72 h after ERCP (group 1) and those operated on more than 72 h after ERCP (group 2). Patients' age, gender, body mass index, American Society of Anesthesiologists Physical Status, abdominal ultrasonography findings, white blood cell count, total serum bilirubin, ALP, amylase, ALT, AST, GGT levels, ERCP findings, time interval between ERCP and LC, conversion rate, median postoperative hospital stay, median operation time, intraoperative complication and postoperative complication rates were collected. RESULTS: There was no significant difference between the demographics of the patients in both groups. The median operation time, median postoperative hospital stay and conversion rate in group 2 were significantly higher than those of group 1. More postoperative complications were seen in group 2. CONCLUSION: Early cholecystectomy after ERCP, within 72 h, has better outcomes, probably due to the inflammatory processes.

Vaginal evisceration after trauma unrelated to previous pelvic surgery.

BACKGROUND: Vaginal evisceration is described as extrusion of intraperitoneal contents secondary to the disruption of the vagina. It is an extremely rare emergency condition. OBJECTIVES: To describe a very rare case of vaginal evisceration that occurred after blunt trauma in a patient with no prior pelvic surgery. CASE REPORT: This report describes vaginal evisceration in a 73-year-old female with no prior pelvic surgery, after blunt trauma. The patient was handled by the cooperation of gynecology and general surgery departments. An immediate surgery was performed after stabilization of the patient and no postoperative complications occurred. CONCLUSION: Whatever be the treatment approach, emergency management of vaginal evisceration is critical to the preservation of a viable bowel. Repositioning of viable bowels into the abdominal cavity and appropriate surgical repair are cornerstones of the treatment.

Effect of oophorectomy and exogenous estrogen replacement on liver injury in experimental obstructive jaundice.

AIM: To investigate the role of estrogen on liver injury in an experimental obstructive jaundice model. METHODS: Three groups of female rats were constituted; group 1 was oophorectomized and given E2 (n = 14), group 2 was oophorectomized and given placebo (n = 14), and group 3 was sham operated (n = 14). Fourteen days following constitution of bile duct ligation, all groups were compared in terms of serum tests, histopathologic parameters, and tissue levels of IFN-gamma and IL-6. RESULTS: The parameters representing both the injury and/or the reactive response and healing were more pronounced in groups 1 and 2 (c2 = 17.2, c2 = 10.20; c2 = 12.4, P < 0.05). In the sham operated or E2 administered groups significantly lower tissue levels of IFN-gamma and higher IL-6 levels were found. In contrast, high IFN-gamma and low IL-6 tissue levels were found in the oophorectomized and placebo group (P < 0.001). Kupffer cell alterations were observed to be more pronounced in the groups 1 and 3 (c2 = 6.13, P < 0.05). CONCLUSION: Our study indicates that E2 impaired liver functions, accelerated both the liver damage and healing. In the conditions of bile duct obstruction, estrogen significantly changed the cytokine milieu in the liver.

Adipokines and ghrelin in gastric cancer cachexia.

AIM: To investigate the roles of the adipocytokines, ghrelin and leptin in gastric cancer cachexia. METHODS: Resistin, ghrelin, leptin, adiponectin, insulin and insulin-like growth factor (IGF-I), were measured in 30 healthy subjects, and 60 gastric cancer patients of which 30 suffered from cancer-induced cachexia and 30 served as a control group. The relationships between hormones, body mass index (BMI) loss ratio, age, gender, and Glasgow Prognostic Score (GPS) were investigated. RESULTS: Cachexia patients had higher tumor stage and GPS when compared with non-cachexia patients (P < 0.05). Ghrelin, resistin, leptin, adiponectin and IGF-I, showed a significant correlation with BMI loss ratio and GPS (P < 0.05). A strong correlation was seen between GPS and BMI loss (R = -0.570, P < 0.0001). Multivariate analysis indicated that BMI loss was significantly independent as a predictor of ghrelin, resistin, leptin and IGF-I (P < 0.05). Existence of an important significant relationship between resistin and insulin resistance was also noted. CONCLUSION: These results showed that serum ghrelin, leptin, adiponectin, and IGF-I play important roles in cachexia-related gastric cancers. No relationship was found between resistin and cancer cachexia. Also, because of the correlation between these parameters and GPS, these parameters might be used as a predictor factor.

Effect of timing of glutamine-enriched enteral nutrition on intestinal damage caused by irradiation.

Intestinal mucosal damage and bacterial translocation are clinical problems that may be caused by the use of ionizing radiation. Glutamine (Gln) support reduces the mucosal barrier in several ways. This study was undertaken to investigate the effect of timing of Gln-enriched enteral nutrition (EN) on bacterial translocation and mucosal damage due to radiotherapy (RT). A rat model of whole body irradiation was designed in which a single dose of 485 cGy was given. A total of 50 rats were randomly assigned to the following 5 groups, each of which comprised 10 rats: (1) balanced rat chow given for 8 days without RT (group 1); (2) balanced rat chow given 4 days before and 4 days after RT (group 2); (3) Gln-enriched EN given 4 days before RT (group 3); (4) Gln;enriched EN given 4 days after RT (group 4); and (5) Gln-enriched EN given 4 days before and 4 days after RT (group 5). Mesenteric lymph node and ileum samples were removed for evaluation of bacterial translocation (BT) and histopathologic investigation, respectively. BT and intestinal mucosal injury scores in all rats that received RT were higher than in rats without RT. No difference was seen in parameters between groups 3 and 4 (P>.05, P>.016, respectively); BT and intestinal mucosal injury scores of group 5 were significantly lower than those of groups 3 and 4 (P<.05, P<.016, respectively). Meanwhile, the BT and mesenteric injury scores of group 5 were significantly lower than those of group 2 (P<.05, P<.016, respectively). As a result, intestinal injury due to RT was significantly decreased by Gln-enriched EN support given before and after whole body RT.

Total relaxivities of material content in various cysts and ameloblastoma: implications for discriminating different fluids.

Nuclear magnetic resonance T(1) and T(2) relaxivities (r(1) and r(2)) exhibit efficiency of a material to alter the relaxation rates (1/T(1) and 1/T(2)), and they are being used for diagnostic purposes. The determination of total relaxivities (r(1t) and r(2t)) of cystic fluid content and ameloblastoma may therefore be useful for discriminative purposes. In order to determine what makes total relaxivities of hemorrhagic cysts, four sets of tubes containing pooled cyst were doped with increasing concentrations of iron, copper, albumin, and gamma-globulins. These sets were replaced in a phantom together with six individual cysts and one ameloblastoma. The relaxation times were measured by magnetic resonance imaging operating at 1.5 T. The relaxivities of individual ions and proteins were determined from the slope of the relation between relaxation rates and concentration, while total relaxivities were determined by using the increases in relaxation rates and material content of cystic fluid (MC). Iron, copper, albumin, and gamma-globulins were found to be the sources of r(1t) and r(2t). Each of r(1t), r(2t), r(1t)MC, r(2t)MC, and r(2t)/r(1t) are distinctive parameters for each cystic category and ameloblastoma. Except for MC, the parameters measured for ameloblastoma are significantly smaller than those of cysts. The similarity of the present results to those used in clinical applications suggests that each of r(1t), r(2t), r(1t)MC, r(2t)MC, and r(2t)/r(1t) has an ability to discriminate various fluids and masses. The present work also suggests that r(1t)MC, r(2t)MC, and r(2t)/r(1t) can be determined in vivo.

MR proton relaxivities of some ions, albumin, and cholesterol added to odontogenic jaw cysts.

The relaxation rates (1/T(1) and 1/T(2)) in cysts have already been analyzed in terms of materials such as albumin, cholesterol, manganese, iron, and copper. However, the relaxivities of these materials have not been determined yet. In this work, five sets containing the ions, albumin, and cholesterol were prepared by addition of increasing concentration of one material to each set. The relaxation times in these sets were measured by MRI, and the relaxation rates were fitted versus concentrations. The slopes of the fits were used as relaxivities. The (r(1), r(2)) values of manganese, iron, and copper in mM(-1) s(-1), and those of albumin and cholesterol in (g/dl)(-1) s(-1) were found to be (32.64, 89.77), (0.31, 1.19), (0.5, 1.479), (0.01, 0.066) and (0.03, 0.458), respectively. The r(2)/r(1) ratio ranged from 2.75 to 15.27. Manganese is an efficient relaxer, but iron and copper are poor ones. Albumin and cholesterol are efficient relaxers for only T(2). The contribution of water associated with native manganese of the cystic fluid to T(1) was 0.268 s(-1), whereas those of water associated with native manganese, albumin, cholesterol, and iron to T(2) were 0.736, 0.185, 0.092, and 0.076 s(-1), respectively. The other contributions were much smaller than 0.076 s(-1). Manganese is most likely the compound altering T(1)-weighted images between different jaw cysts, whereas manganese and albumin are most likely the compounds altering the T(2)-weighted images. Present data suggest that such alterations may be used to separate jaw cysts from other jaw masses. The high r(2)/r(1) suggests that T(2) is a more convenient parameter than T(1) for diagnostic use.

Timing of laparoscopic cholecystectomy for subacute calculous cholecystitis: early or interval--a prospective study.

BACKGROUND/PURPOSE: The aim of this prospective study was to evaluate the safety and feasibility of early laparoscopic cholecystectomy for subacute cholecystitis and to compare it with interval laparoscopic cholecystectomy. METHODS: The study was performed in 74 patients who had been diagnosed with subacute cholecystitis between January 2000 and June 2005. The patients were divided into two groups. The early laparoscopic cholecystectomy group was composed of 31 patients who underwent laparoscopic cholecystectomy 24 h after admission to the hospital. The interval laparoscopic cholecystectomy group was composed of 43 patients who underwent laparoscopic cholecystectomy 8-12 weeks after medical treatment. RESULTS: There was no significant difference between the conversion rate, intraoperative bleeding, need for intraoperative cholangiography, minor bile duct injury, and postoperative complications in the two groups. Eleven patients in the interval group underwent urgent laparoscopic cholecystectomy or additional procedures because of recurrent cholecystitis, choledocholithiasis, or biliary pancreatitis. The early group had a significantly shorter total hospital stay (P = 0.031), lower cost of treatment (P = 0.042), and less difficulty with Calot's triangle dissection (P = 0.008). CONCLUSIONS: Early laparoscopic cholecystectomy can be done without hesitation in patients with subacute cholecystitis, in the light of obstacles observed in the interval group, such as dissection difficulty, lack of success in "cooling down", and additional problems such as choledocholithiasis and biliary pancreatitis.

Results of lateral internal sphincterotomy for chronic anal fissure with particular reference to quality of life.

PURPOSE: The aim of this study was to investigate the effects of lateral internal sphincterotomy on quality of life in patients with chronic anal fissure using the Gastrointestinal Quality of Life Index and the Fecal Incontinence Quality of Life Scale. METHODS: Adult patients with chronic anal fissure underwent lateral internal sphincterotomy with the open technique. Two hundred forty-four patients completed the Gastrointestinal Quality of Life Index questionnaire at admission and at 12 months postoperatively. The Fecal Incontinence Severity Index score was calculated preoperatively and at 2 and 12 months postoperatively. The Fecal Incontinence Quality of Life Scale was administered to any patient who had a Fecal Incontinence Severity Index score greater than 0 at 12 months postoperatively. RESULTS: The mean preoperative Gastrointestinal Quality of Life Index score was 118.34 +/- 6.33, which developed to 140.74 +/- 2.38 postoperatively (P< 0.001). At the two-month follow-up, 18 patients (7.38 percent) had a Fecal Incontinence Severity Index score greater than 0. By 12 months, the number of patients with Fecal Incontinence Severity Index score greater than 0 was reduced to seven (2.87 percent). These seven patients had a Gastrointestinal Quality of Life Index score similar to that of the group with postoperative Fecal Incontinence Severity Index score of 0, and only three patients (1.22 percent) had evident deterioration in the Fecal Incontinence Quality of Life Scale. The 12-month total Gastrointestinal Quality of Life Index score of the three patients who developed anal abscess/fistula after sphincterotomy (139.33 +/- 3.21) was similar to the Gastrointestinal Quality of Life Index score of those without complications. However, the Gastrointestinal Quality of Life Index score of the recurrent cases (111.53 +/- 3.53) was apparently low. CONCLUSION: The gastrointestinal quality of life improved significantly following lateral internal sphincterotomy, regardless of the surgical complications or postoperative disturbances of continence. Only 1.2 percent of the patients experienced deterioration in Fecal Incontinence Quality of Life Scale.

Prospective analysis of 518 cases with thyroidectomy in Turkey.

OBJECTIVE: Thyroid malignancies can present in different manners, among them as asymptomatic solid nodule being the most puzzling. Nodules have been found in the 60-70 % of autopsy specimens and it is very important to rule out the malignancies in such cases. Incidence of carcinomatous changes is reported in 5-15 % of solitary nodules. We present the results of prospective study on 418 thyroidectomies with the aim to review the experience of our unit, to establish the correlation between clinical presentation and histopathology, to discuss the malignancy rates and surgical complications. PATIENTS AND METHODS: Five hundred eighteen consecutive cases of thyroidectomy 419 female (80.8 %), and 99 male (19.2 %) patients performed between January 2002 and October 2004 were included in this prospective study. RESULTS: In 71 (13.7 %) cases the malignancy was found by paraffin specimens, the highest prevalence of malignancy being found in patients with nodular goiter (NG-18 %) followed by 14.6 % in multinodular goiter (MNG). The sensitivity of preoperative fine needle cytology (FNAC) was 83.3 % with false positive rate of 1.3 %. Complications were seen in 5.2 % of cases of which 4 (0.7 %) had hypoparathyroidism and 7 (1.3 %) had recurrent laryngeal nerve injury. All patients observed came from endemic area. Family history nearly doubles the risk of malignancy. CONCLUSIONS: In an endemic area the nodular goiter is the most common. Preoperative cytology, although sensitive, gives a considerable number of false positive results. Results of thyroid surgery at a high volume centre are satisfactory with very low rates of recurrent laryngeal nerve and parathyroid injury. Probability of malignant transformation in a long standing thyroid swelling should always be kept in mind. There appears to be an increase in prevalence of thyroid malignancies in Turkey after Chernobyl disaster.

Clinical presentation and treatment of hyperthyroidism associated with thyroid cancer.

OBJECTIVE: Hyperthyroidism apparently does not protect the patients from thyroid cancer as believed before. In contrast, hyperthyroidism with concurrent thyroid cancer can be diagnosed after pathological examination of unsuspect nodules. The aim of this study was to evaluate the coexistence of hyperthyroidism and thyroid carcinoma and to discuss the advantages of total thyroidectomy in such cases. METHODS: Between January 2002 and October 2004, 120 hyperthyroid patients underwent surgical treatment in our clinic. All patients with hyperthyroidism in this study underwent fine-needle aspiration biopsy and cytologic examination. Frozen section evaluation was performed in all of these patients during the operation. RESULTS: Among these patients 10 had concurrent thyroid cancer. Only one of these patients was examined by fine needle aspiration biopsy prior to operation, while the rest of malignancies was diagnosed from unsuspect nodules. CONCLUSIONS: The selection of appropriate operation procedure appears very important to find out and treat concurrent thyroid cancers. We diagnosed 90 % of thyroid cancers incidentally. If there are no technical difficulties, we prefer total thyroidectomy for the patients with toxic multinodular goiter and Graves' disease with nodules.
