RESUMEN
Abstract Introduction: Soft tissue deposits is tumorous islands apart from lymph nodes and occasionally diagnosed in neck dissection specimens. Their importance has begun to be recognized, however, their value has not been investigated in laryngeal cancer as a single tumor site. Objective: To investigate the prognostic value of soft tissue deposits in patients with laryngeal carcinoma. Methods: Medical records of 194 patients with laryngeal carcinoma who were treated primarily by surgery and neck dissection were reviewed. Prognostic significance of soft tissue deposits was assessed along with other clinical and pathological findings. Recurrence rates, overall and disease-specific survival rates were examined. Results: The incidence of soft tissue deposits was found to be 7.2% in laryngeal carcinoma. N stage was more advanced in patients who had soft tissue deposits. Regional recurrence rate was higher and disease specific and overall survivals rates were significantly lower in patients with soft tissue deposits in univariate analysis. However, in multivariate analysis, soft tissue deposits were not found as an independent risk factor. Conclusion: In laryngeal carcinoma, soft tissue deposits was diagnosed in patients with more advanced neck disease and their significance was lesser than other factors including extranodal extension.
Resumo Introdução: Depósitos de tecido mole são ilhas tumorais diferente dos linfonodos e ocasionalmente diagnosticados em amostras de esvaziamento cervical. Sua importância começou a ser reconhecida, mas seu valor não foi investigado no câncer de laringe como um único local de tumor. Objetivo: Investigar o valor prognóstico do depósito de tecido mole em pacientes com carcinoma laríngeo. Método: Os prontuários de 194 pacientes com carcinoma laríngeo tratados principalmente por cirurgia e esvaziamento cervical foram analisados. O significado prognóstico dos depósitos de tecido mole foi avaliado juntamente com outros achados clínicos e histopatológicos. As taxas de recidiva, as taxas de sobrevida geral e específicas da doença foram avaliadas. Resultados: Observou-se uma incidência de depósitos de tecido mole de 7,2% no carcinoma laríngeo. O estágio N foi mais avançado em pacientes com depósitos de tecido mole. A taxa de recorrência regional foi maior e as taxas de sobrevida geral e específica da doença foram significativamente menores nesses pacientes na análise univariada. No entanto, na análise multivariada, o depósito de tecido mole não foi observado como um fator de risco independente. Conclusão: No carcinoma laríngeo, o depósito de tecido mole foi diagnosticado em pacientes com doença cervical mais avançada, mas sua significância foi menor do que outros fatores, inclusive a extensão extranodal.

OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) is the most common peripheral cause of vertigo. It can be defined as transient vertigo induced by rapid change in head position, associated with a characteristic paroxysmal positional nystagmus. Posterior canal benign paroxysmal positional vertigo is the most frequent form of BPPV. The aim of our study was to investigate and compare the effectiveness of Epley maneuver and Brand-Daroff home exercises for the treatment of posterior canal BPPV. METHODS: A total of 50 patients between 27 and 76 years of age who were diagnosed with unilateral posterior canal into BPPV were randomized prospectively into two groups. In Group-1, modified particle repositioning maneuver and in Group-2 Brandt-Daroff exercises were utilized as treatment. Patients were followed weekly. Cure weeks were recorded. The patients were followed for 12 to 24 months for recurrence. RESULTS: The recovery rates at the first, second and third week controls were 76%, 96% and 100% for Group-1 (modified Epley maneuver) and 64%, 88% and 100% for Group-2 (Brandt-Daroff exercises) respectively. The recovery rates were similar for both groups. The average follow-up duration was 18 months. In Group 1, 7 patients (28%) and in Group 2, 5 patients (20%) had recurrence, which was also similar with no statistical difference. CONCLUSION: It was concluded that both Brandt-Daroff Exercises and Modified Epley maneuvers were almost equally effective in the treatment of BPPV.

OBJECTIVE: To evaluate the association between nasal airway function and Eustachian tube (ET) functions and their impact on tympanoplasty in patients with chronic suppurative otitis media (CSOM). MATERIALS AND METHODS: The study group (CSOM group) consisted of 33 patients scheduled to undergo tympanoplasty for CSOM. Two control groups were formed: a nasal septal deviation (NSD) group of 25 patients scheduled to undergo nasal surgery for NSD, and a control group of 25 healthy individuals with no otologic or rhinologic symptoms. ET functions were assessed tympanometrically with automatic Williams test (ETF1) and modified pressure equalization inflation-deflation test (ETF2) and nasal functions were analyzed using acoustic rhinometry and rhinomanometry. The patients in the CSOM group underwent tympanoplasty, and tests were repeated at the end of the 3rd postoperative month. RESULTS: Both acoustic rhinometry and rhinomanometry revealed similar nasal function in the CSOM and NSD groups, which was inferior to that of the control group. The CSOM group had the worst ET function. Dysfunctional ETs in the CSOM group improved at 3 months postsurgery, and all groups had a similar outcome regarding ET functions. The outcome of ear surgery was not affected by nasal function, and the graft take rate was 90%. CONCLUSION: Patients with NSD had generally poor ET function; however, this did not affect the outcomes of tympanoplasty. The preoperative ET function results were inconsistent with the results following tympanoplasty; therefore, they were not predictive of need for septoplasty. Thus, we do not universally recommend surgical correction of NSD prior to ear surgery; however, this decision should be made on an individual basis.

OBJECTIVE: The authors aimed to determine pulmonary artery pressure and right heart functions in patients with nasal septum deviation (NSD) with echocardiography (EchoCG) and compare the postoperative changes of EchoCG parameters with preoperative findings. METHODS: Seventy-six patients who underwent septoplasty composed the study group. Average age of patients was 23.50 ranging between 18 and 48 years of age. There were 53 males (69.7%) and 23 females (30.3%). Mean pulmonary artery pressure, tricuspid annular-plane systolic excursion, right ventricular diameter, and e/a ratio were measured by EchoCG preoperatively and same parameters were reobtained 3 months after surgery. RESULTS: Mean pulmonary artery pressure reduced from 23.88â± 6.36 to 19.80 ±3.95 mm Hg and tricuspid annular-plane systolic excursion increased from 22.36 ±3.85 to 23.57±3.00 3 months after surgery. It represented statistically significant improvement at right heart functions postoperatively (Pâ<â0.001). Although they were not statistically significant, there was also some improvement in right ventricular diameter and e/a ratio values postoperatively. CONCLUSION: Nasal septum deviation was associated with higher PAP values, which were improved after surgery. Although at a lower extent, a negative effect of NSD on right heart functions was also suspected. Thus, treatment of NSD without delay was proposed, not only to treat the nasal symptoms but possible future cardiovascular complications as well.

OBJECTIVE: To evaluate the impact of nasal septum deviation (NSD) and septoplasty on eustachian tube (ET) functions. MATERIAL AND METHODS: The study was designed as a prospective controlled study and conducted in a tertiary referral center. A study group of 25 patients who were scheduled for septoplasty for NSD; and a control group of 25 healthy individuals having no ear or nose symptoms were formed. Tympanometric analysis of ET function, subjective and objective analysis of nasal functions with acoustic rhinometry and rhinomanometry were performed. Patients in study group underwent nasal surgery and tests were repeated at postoperative 1st and 3rd months. RESULTS: Eustachian tube functions of study group were significantly worse than the control group (Pâ=â0.032). ET functions were found to be poorer as the nasal airway resistances increase which was found to be close to significance (Pâ=â0.056). One and 3 months after corrective surgery, both nasal airway functions and ET functions improved significantly reaching to the level of control group. CONCLUSIONS: Nasal septum deviation was associated with higher rates of ET dysfunction, which could be improved by the nasal surgery. However, in some patients, nasal surgery itself caused ET dysfunction in the early postoperative period.

OBJECTIVE: The aim of the present study was to use constant and customized pressure levels to improve the feedback method of the blood pressure cuff technique in order to decrease intra-subject and inter-subject variability. MATERIALS AND METHODS: The study was conducted in two stages. In the first stage, the relationship between the pressure level generated in the blood pressure cuff and electromyographic response in the sternocleidomastoid (SCM) muscle was investigated. In the second stage, vestibular evoked myogenic potential (VEMP) measurements were made using a custom-built VEMP chair at a constant pressure level of 40 mmHg (P40) or at 50% of the maximum pressure (Pmax50%) that could be generated by the SCM muscle. RESULTS: VEMP measurements were performed on 100 volunteers consisting of 48 males and 52 females whose ages were between 20 and 68 years. The response rate was 41% on a subject basis and 53% on an ear basis. Response rates were similar in males and females, and they decreased with age. The response rate was significantly lower in 11% of the volunteers who could not generate the stipulated 80 mmHg pressure level. Response rates obtained with P40 and Pmax50% were similar, and p13 and n23 latencies and p13-n23 amplitudes obtained from both sides were also similar. Amplitudes were higher in Pmax50% measurements compared to P40, and amplitudes obtained with P40 levels showed greater variance compared to Pmax50%. CONCLUSION: The use of Pmax50% provided reduced variation compared to P40; however, it did not have significant clinical implications. Further studies are needed for the control of many factors that are related to amplitude variability.

OBJECTIVE: Various types of laser, microdrill, and perforator are effectively used in the surgical treatment of otosclerosis. However, they have certain disadvantages along with advantages. The aim of this study was to evaluate the effects of carbon dioxide (CO2) laser and perforator stapedotomy techniques on audiological outcomes and postoperative vestibular functions via videonystagmography (VNG). MATERIALS AND METHODS: This prospective and randomized clinical study was conducted in an academic tertiary medical center. Sixty-nine patients diagnosed with otosclerosis who underwent stapedotomy were enrolled in this study. Patients were divided into two groups based on the technique used in stapedotomy: CO2 laser and perforator. Postoperative hearing gain and VNG findings were the main outcome measures. Subsequently, the two study groups were compared for analysis. RESULTS: The preoperative air-bone gap was 32.7±8.9 decibel (dB) in the study population and it was improved to 12.9±8.4 dB after operation. There were no differences in VNG findings and vertigo symptoms between the laser and perforator groups at postoperative day 2. There was no significant gain difference regarding the air conduction, bone conduction, and air-bone gap between the two groups (p=0.294, p=0.57, and p=0.37, respectively). CONCLUSION: Both CO2 laser and perforator stapedotomy have successful audiological outcomes with no difference in postoperative vestibular disturbance.

OBJECTIVE: Nasal valve area is an important, functional part of nose and there are several different methods that have been used to enlarge that area for a better breathing function. In this study, the authors aimed to study the efficacy of a new spreader graft modification that was crafted in a triangular shape to enlarge nasal valve area. METHODS: Twenty-two patients who underwent rhinoplasty operation with this new technique composed the study group. Average age of patients was 21.4â±â2.1, 13 of them were men (59%) and 9 of them were women (41%). Same surgeon operated all 22 patients with the same technique that included usage of modified triangular spreader graft. Surgical outcomes were assessed by visual analog scale and nasal obstruction symptom evaluation scale preoperatively and 3 months postoperatively. RESULTS: None of the patients had complications or aesthetic deformities according to surgeon after surgery. Average of nasal obstruction symptom evaluation scale score was 64.3 before surgery which reduced to 17.9 at postoperative third month. Also average visual analog scale score was 2.6 before surgery and it was 8.1 3 months after surgery indicating a better breathing sensation (Pâ<â0.001). CONCLUSIONS: Modified triangular spreader graft usage is a safe and effective method to enlarge nasal valve area with satisfactory aesthetic outcomes and good functional results because of its compatibility with anatomic position of nasal valve area.

The studies evaluating the effect of smoking on olfaction reveals opposite results. In vitro and animal studies and epidemiological evidence from volunteers and patients, demonstrated the association between olfaction and erectile functions. In smoking man the reduction of olfactory acuity could adversely affect sexuality. The aim of the present study was to investigate the relationship between erectile dysfunction (ED) and olfactory dysfunction (OD) by comparing a group of healthy adult men with a group of smoking adult men. This prospective study involved 62 volunteers, who were recruited and divided into two groups; one consisted of 35 smoking adult men, and the other included 27 healthy non-smoking men. All participants in both groups were examined in detail for any condition with the potential to cause OD. They all had a normal genitourinary system suffered from no circulatory diseases, diabetes mellitus, hypertension, coronary artery disease nor hyperlipidemia; they had no history of medication affecting genitourinary system. Butanol threshold test and sniffin' stick® (Burghart, Wedel; Germany) screening test was used to asses olfactory functions in both groups. Participants' sexual desire was assessed using an International Index of Erectile Function (IIEF-5) scale. The means of sniffin' sticks scores, butanol threshold scores and IIEF-5 scores were statistically higher in non-smoking group. Butanol threshold scores and sniffin' sticks scores are correlated statistically with IIEF-5 in non-smoking and smoking groups. This study found an association between olfaction and erectile function in smoking and non-smoking men. As far as we know this study is the third published study to show the relationship olfactory and erectile function. In the future studies electrophysiological olfactory methods could be used to confirm in large cohorts the results obtained by the psychophysical approach.

OBJECTIVE: To compare the objective and subjective findings between patients who underwent nasal tip augmentation surgery via two different methods using autogenous auricular conchal cartilage. MATERIALS AND METHODS: This study included the data of 21 patients who underwent nasal tip augmentation surgery. The patients were randomly divided in two groups according to the technique used to form a double layer columellar strut graft; either face to face (group 1) and back to back (group 2). All patients were assessed via nasal obstruction symptom evaluation scale (NOSE) and via acoustic rhinometry and rhinomanometry at preoperative and postoperative 1st and 6th months. RESULTS: There was statistically significant improvement in symptom score in both patient groups with no difference inbetween. Total nasal resistance decreased nonsignificantly at the end of 6th month in both groups; 13.1 Pa/cm3 to 8.6 Pa/cm3 and 10.3 Pa/cm3 to 9.5 Pa/cm3 respectively. There was no significant increment in MCA values for both groups except left MCA1. CONCLUSIONS: We achieved good results in tip augmentation via both techniques. An autogenous conchal cartilage is a good alternative to replace lacking caudal septal cartilage. It provides safe and stable support to the nasal tip. However, further comprehensive studies with larger sample size and long follow-up are required to elucidate any difference between these two techniques.

OBJECTIVES: This study aims to evaluate the efficacy chemoradiotherapy and surgical treatment in patients with hypopharyngeal cancer. PATIENTS AND METHODS: Between January 2003 and July 2009, 48 patients (31 males, 17 females; mean age 55.5±13.4 years; range 29 to 84 years) who were diagnosed with hypopharyngeal cancer were retrospectively evaluated. The patients were assigned into surgery (n=17) and chemoradiotherapy (n=31) groups. RESULTS: The overall survival of the patients with advanced disease in the surgery group was statistically higher than those in the chemoradiotherapy group. The recurrence rate of the patients was 35.3% in the surgery group, whereas it was 41.4% in the chemoradiotherapy group. CONCLUSION: Our study results indicated that the survival rates were higher in the surgery group. On the other hand, chemoradiotherapy had the advantage of laryngeal preservation.

OBJECTIVE: Frey syndrome is one of the most common complications following parotid surgery. The current most common test for objectively diagnosing Frey syndrome is Minor starch-iodine test. This test might be insufficient because its results are not quantitative and therefore tests with quantitative results are investigated. The objective of this study was to investigate the efficiency of galvanic skin response (GSR) test, which measures changes in skin resistance, as a method with quantitative results for diagnosis of Frey syndrome. METHODS: Thirty patients who underwent superficial parotidectomy were assessed postoperatively (mean, 24.7 ± 25.7 months; range, 6-109 months). Patients completed a symptomatic evaluation questionnaire and underwent Minor starch-iodine test and GSR. RESULTS: Diagnostic validity of GSR test was found to be >2.91 following analysis. Sensitivity and specificity of this value were 100% and 55%, respectively, based on symptomatic assessment. Sensitivity and specificity were 87.5% and 57.1%, respectively, based on Minor starch-iodine test. CONCLUSIONS: When compared to symptomatic evaluation of patients who underwent superficial parotidectomy, GSR test was shown to be 100% sensitive in diagnosing Frey syndrome and quantitative results of GSR test could determine severity of Frey syndrome.

OBJECTIVES: This study aims to evaluate the role of sentinel lymph node (SLN) biopsy in patients who had clinically N0 oral cavity cancer in the neck assessment. PATIENTS AND METHODS: Between May 2006 and May 2008, nine patients with clinically N0 oral cavity cancer (6 females, 3 males; mean age 57±24.7 years; range 31 to 71 years) who underwent surgical treatment were enrolled in this study. Eight of them had corpus linguae carcinoma, while one had lower lip carcinoma. Tumor stages were T1 in four, T2 in four patients, and T4a in one patient. The patients underwent surgery within 8 to 16 hours after lymphoscintigraphy was performed for detecting SLNs. Initially primary tumor was excised. Then, SLNs which were identified by a gamma probe, lifting skin flap of the neck were excised. Neck dissection was performed as scheduled. SLNs were examined in frozen sections. The results of frozen section and definitive histopathological diagnosis of SLNs were compared with each other, as well as the definitive histopathological diagnosis of the dissection materials. RESULTS: In all patients SLNs were completely identified and excised successfully, including one node in one patient, two nodes in six patients and three nodes in two patients. All nodes were localized ipsilaterally in the neck. In addition, the frozen section and definitive histopathological examination results of all nodes were consistent. Biopsy results indicated that eight patients were SLN-negative, while one was SLN-positive. Only one patient was SLN-negative, although the pathological diagnosis was found to be N1. CONCLUSION: Our study results suggests that SLN biopsy may be applicable for early stage oral cavity tumors.

OBJECTIVES: To compare the efficacy of nasal antiseptic ointment and silver nitrate cautery in the treatment of children with recurrent epistaxis. METHODS: In this prospective and randomized study, a hundred children with recurrent epistaxis were assigned into two groups. In group 1, patients underwent silver nitrate cauterization, in group 2 patients were treated with nasal antiseptic ointment (oxytetracycline hydrochloride-polymyxin B sulfate); and both groups were followed for 3 months. All of the patients were investigated for allergy with skin prick test. RESULTS: The ages of patients were similar in both groups (group 1: 9.2±2.7; group 2: 8.2±2.2; p=0.069). Thirty-eight percent of the patients in group 1 and 52% of the patients in group 2 had epistaxis in the three months follow-up. The difference between groups was not significant (p=0.159). Thirteen (26%) of the patients in group 1 and 12 (24%) of the patients in group 2 were found to have allergic symptoms and positive prick test. The rate of allergy was similar in both groups (p=0.817). CONCLUSION: Nasal antiseptic ointment and silver nitrate cauterization were found to have similar outcomes in the treatment of recurrent epistaxis.

OBJECTIVES: To evaluate the effects and the predictive value of environmental risk factors on the success of different reconstruction materials used in ossiculoplasty. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral university hospital. PATIENTS: Between January 2007 and October 2010, 110 patients who underwent ossiculoplasty with or without mastoidectomy due to chronic otitis media were enrolled in the study. All patients were classified into 1 of the 3 risk groups (mild, moderate, and severe) according to their measured Middle Ear Risk Index score. INTERVENTIONS: The patients underwent exploratory tympanotomy, tympanoplasty, or tympanomastoidectomy (canal wall-up or wall-down), all with ossicular reconstruction. The ossicular reconstructions were performed using either bone cement, autologous bone interposition, or allograft material. MAIN OUTCOME MEASURES: For each patient, the air-conduction threshold and air-bone gap (ABG) were measured at the 12th month after ossiculoplasty. The ABG gain and air-conduction improvement were compared with preoperative values. The correlation of the success of ossiculoplasty with the middle ear risk group of patients was investigated. Moreover, the efficacy of different types of reconstruction material on the success of ossiculoplasty in the same risk group was evaluated. RESULTS: In the mild- and moderate-risk groups, the ABG gain (p = 0.001 and p = 0.014) and air-conduction improvement (p < 0.001 for both) were statistically significant, whereas those changes were found to be insignificant in the severe-risk group. Moreover, the ABG gain and air-conduction improvement in none of the risk groups revealed a significance in favor of any of the used reconstruction materials. CONCLUSION: The results of this study revealed that none of the reconstruction materials or specific techniques have a superiority in the functional outcomes in patients from the same middle ear risk group. We conclude that the success of ossiculoplasty is highly correlated with the pathophysiological status of the middle ear and is independent of the type of replacement material.

The aim of this study was to investigate the effects of surgical intervention for nasal pathologies on obstructive sleep apnea syndrome (OSAS) and continuous positive airway pressure (CPAP) titrations in patients with OSAS. The study was designed as a prospective case control study. Between December 2007 and June 2010, 31 patients (26 men and 5 women) who were diagnosed with OSAS with polysomnography and confirmed to have obstructive nasal pathology were enrolled in the study. The average age of the patients was 53 ± 9.6 (range 33-68 years) and the body mass index ranged from 22 to 40.6 kg/m(2) with an average of 30.3 ± 4.1. The patients were evaluated with Epworth Sleepiness Scale, OSAS Complaints Questionnaire, visual analog scale, and CPAP titration before and 3 months after nasal surgery. As three patients did not attend the control polysomnography, data analysis was performed on 28 patients. Although there was a significant improvement in the nasal passage and subjective complaints, namely, snoring frequency, apnea and daytime sleepiness, the difference between preoperative and postoperative AHI values was not statistically significant. Postoperative CPAP titration results indicated a decrease both in pressures and in AHI in comparison to preoperative values. These reductions were not statistically significant, although the decrease in CPAP pressures was close to significance (p = 0.062). Nasal pathologies should be treated in all patients with OSAS, particularly those undergoing CPAP treatment. However, patients should be counseled that favorable results might not be achieved after nasal surgery.

OBJECTIVES: We compared the effects of levobupivacaine hydrochloride, bupivacaine hydrochloride, and saline injections in alleviating posttonsillectomy pain. METHODS: Between November 2009 and April 2010, we recruited 60 patients (36 male and 24 female) between 2 and 12 years of age into the study. After informed consent was obtained from the parents, patients admitted for tonsillectomy were randomized into 3 groups by means of sealed envelopes. Group 1 (20 patients; mean age, 6.45+/-2.78 years) received 0.9% sodium chloride (saline solution), group 2 (20 patients; mean age, 5.60+/-2.70 years) received 0.25% levobupivacaine hydrochloride, and group 3 (20 patients; mean age, 5.85+/-2.43 years) received 0.5% bupivacaine hydrochloride infiltrated around each tonsil. Pain was evaluated with McGrath's face scale. RESULTS: The postoperative pain scores at 1 and 5 hours were similar among the groups (p>0.05). The pain scores in the levobupivacaine group were lower than those in the saline group at 13 hours (p<0.017). The pain scores in the bupivacaine and levobupivacaine groups were significantly lower than those in the saline group from 17 to 21 hours until day 6 (p>0.017). There was no difference between the levobupivacaine and bupivacaine groups (p>0.017). CONCLUSIONS: Local infiltration of levobupivacaine is a relatively safe and effective method and is equivalent to use of bupivacaine for posttonsillectomy pain.

OBJECTIVES: This study aims to evaluate the effectiveness of selective neck dissection (SND) in stage pN1 head and neck cancers. PATIENTS AND METHODS: Patients who underwent neck dissection due to squamous cell carcinoma of oral cavity, larynx, oro-hypopharynx were evaluated retrospectively. Sixty-one patients diagnosed with pathological N1 by neck dissection were included in the study. Thirty-four of the 61 necks, to which SND was applied, comprised the study group, and 27 necks, which underwent comprehensive neck dissection (CND), comprised the control group. RESULTS: Neck recurrence rates were 4.9% for all cases, 5.9% for the SND group and 3.7% for the CND group. Two- and five-year disease-specific survival rates were similar for SND group (78.6%, 72.5%) and CND group (90.5%, 82.9%). Two- and five-year overall survival rates were also similar for SND group (67.6%, 58%) and CND group (81.5%, 66%). None of them were significantly different between groups (p>0.05). CONCLUSION: Selective neck dissection provides comparable results to CND in the treatment of pN1 necks.

OBJECTIVES: This study aims to assess the reliability of SleepStrip as a screening test in obstructive sleep apnea syndrome (OSAS). PATIENTS AND METHODS: Seventy-two patients (50 males, 22 females; mean age 51.4±11.1 years; range 20 to 74 years) with OSAS were included in this prospective, non-randomized double-blinded single cohort study between May 2008 and February 2009. Patients who underwent an attended overnight polysomnography (PSG) and consented to participate in the study were asked to use SleepStrip device within the week following PSG recording. The apnea-hypopnea index (AHI) was compared with the SleepStrip score (Sscore). RESULTS: The mean body mass index of patients was 31.1±4.3. Both AHI and Sscore were obtained in 64 patients. There was a strong correlation between Sscore and AHI (r=0.76, p<0.001). The sensitivity and specificity of the SleepStrip were 94.4% and 93.5% when used to diagnose cases with AHI = or >40. The sensitivity and specificity of the SleepStrip was reduced to 80% and 87.2% when AHI threshold was chosen as = or >25 and 83.3% and 76.5% for AHI = or >15 respectively. CONCLUSION: There is a strong correlation between SleepStrip and AHI. SleepStrip was found to be effective in diagnosing severe OSAS with AHI = or >40, however, its diagnostic capability was reduced in patients with lower AHI's who constitute the main target of screening.
