RESUMEN

AIMS: Olfaction and gustation in patients with diabetes mellitus have great significance on quality of life, and their impairment may result in possible hazards. A limited number of studies have been performed to determine the alteration of both gustatory and olfactory function in type 2 diabetic patients with diabetic peripheral neuropathy (DPN). The aim of this study was to determine whether type 2 diabetic patients, with and without DPN, exhibit major olfactory and gustatory dysfunction using validated and dependable techniques. METHODS: An observational-analytical case-control study was conducted. Sixty patients with type 2 diabetes mellitus (T2DM) and 30 healthy control subjects with a mean age of 57.1 ± 8.4 were included in the study. Patients with T2DM were recruited from the endocrinology outpatient clinic. After clinical evaluation and electromyography examination, patients with T2DM were divided into the 2 groups, with and without DPN. After a 10-hour fasting period, blood samples were taken for the measurement of serum creatinine, lipids, and HbA1c. For the quantitative assessment of olfactory function, all participants underwent butanol threshold test and odour identification test. Gustatory function was tested administering a whole-mouth above-threshold test using sucrose solutions. RESULTS: The control subjects showed significantly higher Sniffin' sticks and butanol threshold scores than the diabetic patients without DPN (P = .001 and P = .009). No significant difference was found in the gustatory function test between these 2 groups (P = .116). Diabetic patients with DPN had lower Sniffin' sticks scores, butanol threshold scores, and higher sucrose thresholds compared to the controls (P < .001, P < .001, and P = .002). There were no significant differences between diabetic patients with or without DPN regarding Sniffin' sticks scores, butanol threshold, and sucrose thresholds (P = .302, P = .181, and P = .118). CONCLUSION: In conclusion, this study demonstrates that T2DM is associated with olfactory and gustatory dysfunction. The fact that there was no difference between the diabetic patients with and without DPN elicits the idea of central neuropathy. This novel finding might facilitate the addition of olfactory and gustatory tests to the methodological spectrum of afferent pathway investigations.

RESUMEN

The aim of this study is to compare the inlay butterfly transcanal cartilage tympanoplasty with the conventional underlay tympanoplasty. Operation time, pre- and postoperative hearing levels, successful closure rate of tympanic membrane (take rate) and long-term re-perforation in dry perforated chronic otitis media were evaluated. The study design consists of case series with a chart review. The study settings are tertiary referral center. Of the 72 patients (age range 14-57 years) with dry perforated chronic otitis media, 29 patients underwent inlay butterfly transcanal cartilage tympanoplasty (group 1) and 43 patients underwent conventional underlay tympanoplasty without mastoidectomy (group 2) between January 2010 and June 2012. The outcome measures were the duration of surgery, "take rate" at the 30th postoperative day and the audiometric results at the 45th postoperative day. Long-term re-perforation was evaluated at least postoperative 1 year. The graft take rate was 96.5 % in group 1 and 90.7 % in group 2 at the 30th postoperative day (p > 0.05). Mean air-bone gap was improved from 18.8 ± 8.09 to 11.9 ± 7.12 dB in group 1 and from 21.9 ± 7.32 to 11.6 ± 8.43 dB in group 2. The improvement of air-bone gap in both groups was statistically significant (p < 0.05) but the improvement between the groups was not statistically significant (p > 0.05). The average duration of the surgery was 29.9 ± 5.38 min for inlay tympanoplasty group and 58.9 ± 12.1 min for underlay tympanoplasty group (p < 0.05). Two patients in group 2 had re-perforations after an initial take of the graft in 1-year follow-up period. Inlay butterfly transcanal cartilage tympanoplasty is a good choice in selected cases. Although this technique has the similar take rate and audiological results with conventional underlay tympanoplasty, it is a time-saving procedure.

RESUMEN

BACKGROUND: The medications may enhance the recovery after nerve paralysis. We aimed to evaluate the effects of aminoguanidine (AG), melatonin, and methylprednisolone on peripheral facial nerve neurorrhaphy. METHODS: The buccal branch of the facial nerve was transected and autografted in 32 New Zealand rabbits. Subjects were divided into 4 groups equally (AG, melatonin, methylprednisolone, and control). After the medical treatment latency and amplitude were measured with nerve conduction study at 3, 6, and 10 weeks. Then, coapted segments of nerve were examined microscopically. The groups were compared with each other. RESULTS: The latent period was shortened, and the amplitudes were increased in the AG group; the latent period was shortened, and the amplitudes did not show significant change in the melatonin group with the time. There were no significant differences between the amplitudes at 3 to 6 and 3 to 10 weeks in the methylprednisolone group, and the latent period was shortened. There was no significant difference between the amplitude values at 3, 6, and 10 weeks in the control group. In the histological examination, AG had the best influence on preventing myelin degeneration and reducing the accumulation of myelin debris. Considering the increase in collagen fibers, the best results were achieved in the melatonin group. The degree of myelin-axonal degeneration was higher in the methylprednisolone group. The degree of collagen fiber increase, axonal degeneration, myelin degeneration, and the accumulation of myelin debris were detected quite high in the control group. CONCLUSIONS: Aminoguanidine and melatonin alone achieved an increase in regeneration after peripheral facial nerve neurorrhaphy, but methylprednisolone did not. The best healing was determined in the AG group.

RESUMEN

We aim to define a cartilage reshaping and repositioning technique for caudal septal dislocations, with the logic of adapting the smoother tissues to the stiffer structures. The study was designed retrospectively with the patient charts and photographic analysis. Thirty-six patients who had septal surgery in a septoplasty or an open approach septorhinoplasty operation and meet the inclusion criteria were evaluated for the study. Postoperative success of the technique was based on preoperative and postoperative photographic analysis by two independent otorhinolaryngologists. The estimators classified 33 cases as near complete, 3 cases as improved but persisting caudal septal deviation, and any cases with no change. The improvement of the degree of reconstruction was near complete about 87% in septoplasty and 95% in septorhinoplasty groups, and 92% for all patients. In this study, we present a caudal septal repositioning maneuver which achieves a stable anchorage between postero-caudal septal cartilage and nasal spine. Septal cartilage is notched and fixed to nasal spine with two simple independent sutures as lock and key model. We define this maneuver as riding spine technique. It is an anatomic re-orientation between the septum and nasal spine for caudal septal deviations and subluxations.

RESUMEN

The objective of this study is to compare the topical administration of bupivacaine hydrochloride, saline and bupivacaine hydrochloride infiltration on post-tonsillectomy pain in children. Sixty children undergoing tonsillectomy were enrolled in the study. Patients were randomized into three groups using sealed envelopes. Group 1 (n = 20) received topical 0.5 % bupivacaine hydrochloride, group 2 (n = 20) received topical 0.9 % NaCl (saline), and group 3 (n = 20) received 0.5 % bupivacaine hydrochloride infiltrated around each tonsil. Pain was evaluated using McGrath's face scale. Pain scores in topical bupivacaine hydrochloride group was significantly lesser than the topical saline group at 5th, 13th, 17th and 21st hours, until the 6th day (p < 0.017). Moreover, pain scores of topical bupivacaine hydrochloride group was superior to bupivacaine hydrochloride infiltration group at 5th, 13th, 17th hours and 2nd, 3rd, 4th and 5th day (p < 0.017). There were significantly lesser morbidities in topical bupivacaine hydrochloride than saline group in 1st and 4th day (p < 0.017). Topical administration of bupivacaine hydrochloride proved to provide more efficient pain control than bupivacaine hydrochloride infiltration.

RESUMEN

Primary lymphoma of the paranasal sinuses is a rare entity. Most cases are reported to occur in the maxillary and ethmoid sinuses as well as the nasal cavity. Primary involvement of the frontal sinus is very rare. We report a 68-year-old man with a diagnosis of B-cell lymphoma (non-Hodgkin lymphoma) originating from his frontal sinus.

RESUMEN

The aim of this study was to investigate the relationship between obesity and otitis media with effusion. 471 cases with ages between 4 and 12 years were included. Of the 471 cases, 204 cases (97 girls, 107 boys) were diagnosed OME, the study group, 267cases (127 girls, 140 boys) were the control group. Body mass index of the two groups were compared to each other. The average body mass index for girls in all age groups was 17.93 ± 1.92 (n: 97) for cases with OME and 16.67 ± 1.28 (n: 127) for the control group.(p < 0.05). The average BMI for boys in all age groups was 18.25 ± 1.98 (n: 107) for cases with OME and 16.30 ± 1.26 (n: 140) for the control group. (p < 0.05). Children with a BMI greater than or equal to the 85th percentile were considered to be overweight or obese. Regarding the girls, of the 97 cases with OME, 23 cases were overweight, whereas of the 127 control cases, 7 cases were found to be overweight. This difference was statistically significant (p < 0.05). Regarding the boys, of the 107 cases with OME, 29 cases were overweight, whereas of the 140 control cases, 13 cases were found to be overweight. This difference was also statistically significant (p < 0.05). It is concluded that childhood obesity and overweight may play a role as a predisposing factor in the development of OME. It is also noted that even if a child is in the normal range of BMI percentile (less than 85th percentile; not obese or overweight), as the BMI increases, the relative risk of developing OME increases.

RESUMEN

OBJECTIVES: In this study patients who had locoregional recurrence of lower lip carcinomas after therapies such as surgery, electrocoagulation, cryotherapy or traditional local therapies are discussed. PATIENTS AND METHODS: The records of 16 cases (1 female, 15 males; mean age 58 years; range 30 to 83 years) with recurrent lower lip carcinoma admitted between March 2002 and September 2007 to Dr. Abdurrahman Yurtarslan Oncology Training and Research Hospital, Ear, Nose and Throat Department were retrospectively reviewed. RESULTS: Fourteen patients had been treated in other institutions, while two had been treated in our center. Four of the patients had recurrence in the lip, four patients had recurrence only in the neck, and the remaining eight patients had both lip and neck recurrence. Ten patients received modified radical or radical neck dissection because of their palpable lymphadenopathies, three patients received supraomohyoid neck dissection due to non palpable lymphadenopathies, and the remaining three patients did not have neck dissection because of co-morbid diseases. Seven patients (43%) died in the first postoperative year because of lower lip carcinomas and three patients died because of other reasons. Six patients survived for the first two years without any evidence of disease. CONCLUSION: Patient survival will be affected by the applied treatment. For patients with primary lower lip cancers, otolaryngologists experienced in oncology must plan surgery rather than local treatments. In case of locoregional recurrence, immediate treatment should be planned.

RESUMEN

INTRODUCTION: The eradication of the middle ear disease is mentioned as the fundamental principle of tympanoplasty. The presence of some factors related to patient or disease itself forces the physician to classify the chronic ear disease as high-risk perforations. The aim of this study was to present a tri-layer tympanoplasty technique and its otological and audiological outcomes in the ears with high-risk perforations. MATERIALS AND METHODS: This retrospective study was carried out on a total of 46 eligible ears that had chronic otitis media with high-risk perforations. Preoperatively, 17, 15, and 14 ears were reported with Sade classification grade 4 pars tensa retraction (Group 1), total or near-total tympanic membrane perforation (Group 2), and a history of ear surgery (Group 3), respectively. All the cases had tympanoplasty using the tri-layer technique at a tertiary center during 2008 and 2014. A review of the patients' chart showed that 46 patients underwent tri-layer tympanoplasty. Regarding the audiological outcomes, the comparison of pre- and post-operative results revealed mean air conduction level and mean air-bone gap (ABG) of 4 different frequencies in dB according to a new standardized format for reporting hearing outcome in clinical trials. RESULTS: The mean value of the follow-up period was reported as 29.22±3.23 months. Graft take rate was 93.4 % in all the cases, as well as 94.1%, 100%, and 85.7% in Group 1, Group 2, and Group 3, respectively. The mean values of ABG were improved from 35.17±6.64 to 23.52±10.4, 30.46±5.89 to 17.20±8.04, and 29.14±8.37 to 16.14±5.02 dB in Group 1, Group 2, and Group 3, respectively (P<0.05). CONCLUSION: Tri-layer tympanoplasty is a reliable procedure in the surgical treatment of the chronic otitis media with high-risk re-perforations.

RESUMEN

Mulberry hypertrophy occasionally coexists with sinonasal pathologies. There are very few reports in the literature on this clinical entity. We conducted a retrospective study to draw attention to this condition in the context of accompanying sinonasal pathologies. Our study group was made up of 68 patients-51 males and 17 females, aged 13 to 57 years (mean: 34.9)-who had been diagnosed with mulberry hypertrophy and at least one accompanying sinonasal pathology. All patients had a long-standing chronic discharge. Forty-nine of these patients (72.1%) had unilateral mulberry hypertrophy. The most common concomitant pathologies were chronic rhinosinusitis and ostiomeatal complex disease; others included septal deviation, nasal polyposis, allergic rhinitis, and concha bullosa. Thirty-six patients (52.9%) with varying degrees of choanal/nasal obstruction were operated on with endoscopic excision to treat the mulberry hypertrophy. In all, most patients underwent some sort of surgery to treat either the mulberry hypertrophy or the accompanying sinonasal pathology. Based on our findings, we suggest a clinical staging system to serve as a way to standardize management and guide future basic and clinical research.

RESUMEN

INTRODUCTION: Aminoglycosides (AGs) have been widely used for potential life-threatening bacterial infections. Although AGs are well known for their ototoxic side effects, some AGs such as amikacin are considered less harmful to auditory functions; thus, auditory monitoring is mostly neglected during treatment with these drugs. OBJECTIVE: To reflect the potential auditory hazards of repeated amikacin use on the patients with cystic fibrosis (CF). METHOD: 32CF patients with prior exposure to at least 3 courses of amikacin (the CF group) and 35 non-CF patients visiting the outpatient clinic with any complaint other than hearing loss and no history of treatment with any AG(the control, or C group) were compared with pure-tone audiometry(PTA). The diagnosis of CF was made by Nanoduck sweat test. RESULTS: The average age of the participants were 8.25 ± 2.76 years in the CF group and 8.58 ± 2.00 years in the C group (ranging from 5 to 13 years). 29 (43.28%) of the cases were female and 38 (56.71%) were male. Clinical SNHL(sensorineural hearing loss) was detected in 4 of the 32 subjects in the CF group. None of the subjects in the C group exhibited clinical SNHL. There was no statistically significant difference between the groups with regard to presence or absence of clinical SNHL (p > 0.05). However, hearing levels of the CF group were around 20 dB(decibel) HL(hearing loss), whereas hearing levels of the C group were around 5 dB. This difference was statistically significant for the pure tone averages of both all frequencies and speech frequencies (p < 0.05). CONCLUSION: Repetitive exposure to AGs can cause permanent, although mild, sensorineural hearing loss. For prevention, hearing status of the patient should be closely monitored and treatment of choice should be precisely tailored according to the audiological evaluation. This is especially important in patients with CF who frequently experience medical conditions necessitating AGs use.

RESUMEN

OBJECTIVES: Pharyngocutaneous fistula is a serious complication after total laryngectomy, and there are some risk factors stated in the literature. The surgical suture techniques are not studied so much. The aim of this study is to evaluate the effectiveness of 'modified continuous mucosal Connell suture' on the incidence of pharyngocutaneous fistula after total laryngectomy. METHODS: This is a retrospective case series study based at a tertiary center with 31 patients who underwent total laryngectomy between July 2011 and December 2013. Pharyngocutaneous fistula formation after total laryngectomy was evaluated with the patients who underwent modified continuous mucosal Connell suture for pharyngeal repair. RESULTS: Pharyngocutaneous fistula was observed in only one patient (3.2%) who had a history of previous radiotherapy, and it was spontaneously healed within 6 days by conservative treatment. CONCLUSION: We defined a new suture technique for the pharyngeal repair after total laryngectomy. This technique is a simple modification of continuous mucosal Connell suture. We named it as zipper suture. It is effective in the prevention of pharyngocutaneous fistula for pharyngeal reconstruction after total laryngectomy.

RESUMEN

INTRODUCTION: Congenital cholesteatoma is thought to be caused by inadequate folding of the epidermoid formation inside the middle ear cleft. During development of the middle ear mucosa, stratified squamous epithelium accumulates in the embryonic life. Its typical appearance is a "pearl" beneath the anterosuperior quadrant of the tympanic membrane. PRESENTATION OF CASE: We report 28 years-old case with congenital cholesteatoma in the posterosuperior quadrant of middle ear cavity. The main complaint was the hearing loss which had developed slowly over several years. DISCUSSION: The case was surgically treated. Postoperative hearing result was satisfactory. CONCLUSION: Congenital cholesteatoma may occur in atypical locations and ages. Many authors prefer canal wall down tympanomastoidectomy. But it can also be treated successfully by intact canal wall tympanomastoidectomy with good hearing results.

RESUMEN

INTRODUCTION: The treatment of cervical lymph node metastases have a significant prognostic effect on the face and forehead skin cancers. We aimed to point out the importance of loco-regional treatment in cutaneous squamous cell carcinoma of face and forehead. PRESENTATION OF CASE: We present our experience with four cases that had squamous cell carcinoma of face and forehead skin. All cases had regional recurrence following 1-3 years after the primary treatment, but did not have local recurrence. DISCUSSION: Loco-regional lymphatic treatment for face and forehead skin squamous carcinomas has vital importance especially in the cases with high-risk factors for lymph node metastasis. CONCLUSION: Elective lymph node dissection of appropriate region(s) should be included in the treatment plan for cases which have one or more of high-risk factors for lymph node metastases and long-term follow-up should not be ignored.

RESUMEN

ABSTRACT: The anatomy of the sinonasal area has a very wide rage of anatomical variations. The significance of these anatomical variations in pathogenesis of rhinosinusitis, which is the commonest disease in the region, is still unclear. The aims of the study were to compare the rate of sinonasal anatomical variations with development and severity of chronic rhinosinusitis patients. CT scan of paranasal sinuses images of 99 individuals were retrospectively reviewed. 65 cases of chronic rhinosinusitis (study group) who had undergone endoscopic sinus surgery were compared with 34 cases without chronic rhinosinusitis (control group). Also in study group Lund-Mackay score of the sinus disease were calculated and compared to the rate of related anatomical variations. There were 74 (74.7 %) males and 25 (25.2 %) females with ages ranging from 13 to 70 years (mean 32.2 years). The anatomical variations recorded were: Septal deviation 47 (72.3) in study and 25 (73.5 %) in control group, concha bullosa 27 (41.5 %) in study and 18 (52.9 %) in control group, overpneumatized ethmoid bulla 17 (26.1 %) in study and 14 (41.1 %) in control group, pneumatized uncinate 3 (4.6 %) in study and 3 (8.8 %) in control group, agger nasi 42 (64.6 %) in study and 19 (55.8 %) in control group, paradoxical middle turbinates 9 (13.8 %) in study and 4 (11.7 %) in control group, Onodi cell 6 (9.2 %) in study and 2 (5.8 %) in control group, Haller's cells (infraorbital ethmoid cell) 9 (13.8 %) in study and 7 (20.5 %) in control group. None of these results were statistically significant between study and control group (p > 0.05). Lund-Mackay score (which was assumed to show the severity of the disease) of the maxillary, ethmoid and frontal sinus were calculated and compared to rate of septal deviation, concha bullosa, agger nasi cells. No significant correlation was conducted (p > 0.05). The results of study showed no statistically significant correlation between sinonasal anatomical variations and pathologies of the paranasal sinus. Also these anatomical variations did not increase the severity of pre-existing sinusitis significantly. LEVEL OF EVIDENCE: This is a retrospective cohort study (2b).

RESUMEN

Lymphangiomas are rare congenital tumors of the lymphatic system, most often encountered during childhood. Although the most frequent locations for lymphangioma are the head and neck region, isolated involvement of the nasopharynx is very rare and only two cases have been reported since 1969. We report a case of a 60-year-old male with a nasopharyngeal mass that presented with nasal obstruction. The surgical excision of mass was performed by a combined transoral and transnasal endoscopic approach. Histopathological evaluation revealed the diagnosis as lymphangioma. After a follow-up of 18 months the patient is free of recurrence.

RESUMEN

The biological mechanisms of cancer and associations with behavior of tumours need to be studied to understand progression and determine appropriate treatments. Here we investigated expression of VEGF, MMP-9 and E-cadherin in laryngeal SCCs and their relations with clinical behavior. This prospective study was based on 38 surgical specimens from patients with primary laryngeal SCC and data recorded in their cards. Expression of the three factors in tumor tissue was examined using immunohistochemistry and correlations with clinical parameters of primary tumors, regional lymph node metastases, stage of disease, histopathologic differentiation, and vascular/cartilage invasion were investigated. Regarding the cases with positive MMP-9 expression, the difference between well and moderately/poorly differentiated tumors was statistically significant. However, differences between early stage (stage I and II) and late-stage (stage III and IV) tumours, and between positive and negative for pLN metastasis were not. No significant relationship between positive VEGF and tumor differentiation or stage was apparent, but E-cadherin levels significantly differed between well and moderately/ poorly differentiated tumours and with the presence of pLN metastasis. E-cadherin staining did not vary between MMP-9 positive and negative cases. In conclusion, MMP-9 may be a negative predictor of differentiation in laryngeal SCC, while E-cadherin is a predictor of differentiation and nodal metastases. Even if the difference between VEGF expression and tumor stage was not statistically significant, it seems that there exists some relationship, which might be clarified with a greater number of cases.

RESUMEN

Cervical lymph node metastasis is the most important prognostic factor in patients with head and neck carcinoma. We retrospectively analyzed the effects of three different variables-tumor size, degree of differentiation, and depth of invasion-on the risk of neck node metastasis in 50 adults who had been treated with surgery for primary squamous cell carcinoma of the oral cavity. Primary tumor depth and other pathologic features were determined by reviewing the pathology specimens. Preoperatively, 36 of the 50 patients were clinically N0; however, occult lymph node metastasis was found in 13 of these patients (36.1%). The prevalence of neck node metastasis in patients with T1/T2 and T3/T4 category tumors was 51.5 and 58.8%, respectively. The associations between the prevalence of neck node metastasis and both the degree of differentiation and the depth of invasion were statistically significant, but there was no significant association between neck node metastasis and tumor size. We conclude that the prevalence of neck lymph node metastasis in patients with squamous cell carcinoma of the oral cavity increases as the tumor depth increases and as the degree of tumor differentiation decreases from well to poor, as has been shown in previous studies. It is interesting that tumor size, which is the most important component of the TNM system, was not significantly associated with neck node involvement.
