Anatomic variations of sphenopalatine artery and minimally invasive surgical cauterization procedure.

Background Sphenopalatine artery (SPA) ligation or cauterization stands to be one of the most common management options of refractory epistaxis. Ramification pattern of SPA as it passes through sphenopalatine foramen (SPF) has not been clearly established. The aim of this study is to investigate situations in which middle meatal approach may fail due to anatomic variations of SPA and to define a minimally invasive surgical cauterization procedure. Anatomic variations of SPA were determined by microdissection of 20 adult sagittally cross-sectioned head specimens. Methods Branching characteristics of SPA and its anatomic relations were evaluated and anatomic variations were noted. Results SPA was generally (80%) forming branches within SPF before entering into the nasal cavity. In 20% of the specimens, SPF was located superior to the horizontal lamella of the middle turbinate, and accessory foramen was present in 10%. In 10% of the cases, the posterior lateral nasal branch was situated as two branches in a deep sulcus in the middle meatus. Conclusion The ramification pattern of SPA can not be fully exposed without resection of the posterior part of the middle turbinate via the middle meatal approach. Two-step procedures are advocated in reducing failure rates. Previously defined two-step procedures are relatively invasive. A less invasive procedure is defined based on the variations of SPA and SPF.

Single-shot, low-dose intratympanic gentamicin in Ménière disease: role of vestibular-evoked myogenic potentials and caloric test in the prediction of outcome.

OBJECTIVE The aim of this study was to assess the efficacy and safety of single and low-dose intratympanic gentamicin therapy in patients with Ménière disease and who were monitored both with caloric tests and vestibular-evoked myogenic potentials (VEMPs) to see if VEMPs have an additional role in predicting the efficacy of the drug. STUDY DESIGN This is a prospective cohort study. SETTING Tertiary referral center is the study setting. PATIENTS Twenty-five intractable Ménière disease patients were included as the study group. INTERVENTION(S) Low-dose (16 mg/mL), single-shot intratympanic gentamicin was applied. VEMP and caloric test were applied 2 weeks after the application. MAIN OUTCOME MEASURE(S) Safety and efficacy of protocol were evaluated at the sixth month postoperatively with tonal audiogram and visual analog scale, respectively. RESULTS Mean average pure-tone hearing threshold at 0.5, 1, 2, 4, and 8 kHz was 49.6 and 51.0 dB before and after the application, respectively (P > .05). Mean pretreatment and posttreatment visual analog scale scores of patients were 17.6 mm (10-30 mm) and 74.6 mm (41-100 mm), respectively (P < .01). Posttreatment VEMPs were absent in 17, deteriorated in 2, and not changed in 6 patients. VEMP was a significant predictor of posttreatment visual analog scale score, whereas caloric test was not (P < .01). CONCLUSIONS Low-dose, single-shot intratympanic gentamicin treatment proved to be effective and safe among intractable Ménière patients. VEMPs obtained at posttreatment second week were significant predictors of patients posttreatment sixth-month dizziness status and vertigo control.

Blood supply of the inferior turbinate and its clinical applications.

One of the most effective treatments of inferior turbinate (IT) hypertrophy is surgical reduction. Bleeding from the IT branch of the posterior lateral nasal artery (ITB) may interfere with the outcome of IT surgery. The aim of this study is to define the anatomic localization of the ITB and its variations and to investigate its clinical importance. Anatomic relations of the ITB were determined by microdissecting 20 adult, sagittally cross‐sectioned head specimens. Branching characteristics of the ITB and its anatomical relations were evaluated. The most consistent two markers to define the ITB on the lateral nasal wall were the posterior attachment of the IT (PAIT) and the posterior attachment of the middle turbinate (PAMT). Mean horizontal distances of the ITB from the PAIT and the PAMT were 7.2 mm ± 2.8 mm (2.5–11.8 mm) and 8.2 mm ± 2.8 mm (4–14.6 mm), respectively. ITB was the only major artery that supplied the IT in 85% of the specimens, and, in 15%, there was more than one artery. ITB was located lateral to the IT in 95% and medial to the IT in 5%. The ITB coursed on the lateral nasal wall, vertically between the middle and ITs and always anterior to the PAIT. All the variations of blood supply to the IT were within a one square centimeter area, ∼1‐cm anterior to the PAIT. Successful cauterization of this particular area may be an alternative cauterization site in IT surgery. Clin. Anat. 23:770–776, 2010.

Long-term Follow-up of Positive Surgical Margins in Basal Cell Carcinoma of the Face.

BACKGROUND Basal cell carcinoma (BCC) in central facial locations and tumors with positive margins are at a higher risk of recurrence. The most effective treatment is total excision, which includes an adequate pathological margin. OBJECTIVE To evaluate the outcome of the patients who underwent surgery for BCCs of the head and neck and of those who had positive surgical margins where Mohs surgery is not available. METHODS This study was conducted at Ege University Medical School between 2004 and 2014. One hundred thirty patients with 154 BCC who underwent surgical excision were included. In the histopathologic report, the existence of positive margin, BCC subtype, localization of the tumor, and distance of margins to the tumor were evaluated. RESULTS Twenty-three lesions (14.9%) of 22 patients revealed positive surgical margins. Six patients (26.1%) had recurrences on the surgical site. The BCC subtypes of recurrent patients were reported to be multifocal superficial in 2 (33.3%), infiltrative (16.7%) in 1, and micronodular (50%) in 3. CONCLUSION Patients with superficial multifocal or micronodular tumors should undergo reoperation because of high recurrence rates.

Acute invasive fungal rhinosinusitis: Survival analysis and the prognostic indicators.

Background Acute invasive fungal rhinosinusitis (AIFR) is a highly mortal, progressive fungal infection of the paranasal sinuses and surrounding structures that is almost always seen in patients who are immunocompromised. Despite the use of newer antifungal treatments and early diagnosis, the prognosis of AIFR does not improve significantly. Due to the higher incidence of patients who are immunocompromised and have more complex disease, AIFR is a growing medical issue in tertiary medical centers. Objective The aim of this study was to present the outcomes and analyze the prognostic indicators of patients with AIFR who underwent surgery. Methods Between October 2009 and November 2014, 37 patients who underwent surgery for AIFR at a tertiary care university hospital were included in the study. Overall survival and disease-specific mortality and survival rates were calculated to estimate survival function. The impact of age, sex, underlying disease, extent of AIFR, applied medical treatment, and causative species (mucormycosis, aspergillosis) were also taken into consideration. Also, the effect of a variety of laboratory parameters, such as hemoglobin, leukocyte, neutrophil, lymphocyte, platelet, and C-reactive protein (CRP) levels, to survival were evaluated. Results The median follow-up time was 58 days (interquartile range = 304). Overall and disease-specific mortality rates were 64.9 and 51.4%, respectively. Fever was the most common symptom (86.5%), along with nasal obstruction and/or fullness (48.6%) and epistaxis (48.6%). Age and sex did not have a significant impact on survival (p > 0.05). Palate involvement was significantly associated with mortality (p < 0.05). According to the results of Cox, regression analysis for disease-specific mortality rate, leukocyte and neutrophil counts as well as CRP levels had a significant effect on survival function (p < 0.05). Conclusions Palatal involvement was associated with a higher mortality in our study. Also, leukocyte counts, neutrophile counts, and CRP values had a significant impact on survival function. The reversal of the underlying disease and immunosuppression is as important as the medical and surgical treatment.

Results of multiple-frequency tympanometry measures in normal and otosclerotic middle ears

Tympanometry is a non-invasive, quick, and inexpensive method for examining the middle-ear function. Its limited value in differentiating otosclerotic from normal middle ears caused researchers to develop new methods for evaluation of middle ears. Resonant frequency had been found to be higher in otosclerotic middle ears than normals. We conducted multiple-frequency tympanometry measurements in 25 surgically confirmed otosclerotic ears and 100 normal ears. Mean middle-ear resonant frequency for the otosclerotic group was found to be 1190 Hz and mean middle-ear resonant frequency of the control group was 934.6 Hz (p<0.001). With a cut off value of 1025 Hz (based on 95% confidence interval), sensitivity was 80% and specificity was 82%. The present findings confirm the advantage of the resonant frequency estimation over conventional tympanometry in detecting middle-ear status and mechanics in patients with otosclerosis. As a conclusion, detecting resonant frequency when evaluating patients for otosclerosis must be an essential part of examination. Nevertheless, further investigation is necessary for better diagnosis of otosclerosis preoperatively.

Post-Surgical and Oncologic Outcomes of Supracricoid Partial Laryngectomy: A Single-Institution Report of Ninety Cases

Objective: The aim of this study was to report the post-surgical and oncologic outcomes of patients who underwent supracricoid partial laryngectomy (SCPL). Methods: 90 patients who underwent SCPL between 1994 and 2014 were reviewed. 45 patients underwent cricohyoidopexy (CHP) and 45 patients cricohyoidoepiglottopexy (CHEP). Median nasogastric (NG) tube removal time, decannulation time, overall survival, disease-free survival and local control rates were calculated. The effect of the type of surgery on functional and oncologic outcomes were assessed. Results: Median NG tube removal time was 16.5 days (IQR = 10) and 14 days (IQR = 9) in CHP and CHEP patients, respectively (p > 0.05). Median decannulation time was 30 days (IQR = 26) and 19 days (IQR = 15) in CHP and CHEP patients, respectively (p < 0.05). Resection of one arytenoid significantly increased NG tube removal time. Median follow-up time was 55 months. There were 15 oncologic failures and the median time interval for tumor recurrence was 9 months. Five-year overall survival rate was 80.4%. The 3- and 5-year disease-free specific survival rates were 81.7 and 76.7%, respectively. Conclusions: Given the more extensive surgery applied for CHP, functional outcomes were better in patients with CHEP. Resection of an arytenoid had a negative outcome on swallowing.

The Value of Sentinel Lymph Node Biopsy in Oral Cavity Cancers

Objective The aim of this study was to establish the effectiveness of sentinel lymph node biopsy in the detection of metastasis in N0 necks of T1-T2 early-stage oral cavity cancers. Materials and Methods Twenty neck dissections were performed in 18 patients diagnosed with T1 and T2 oral cavity cancer, with an indication for elective neck dissection between November 2007 and January 2011. The male to female ratio was 12:8, with a mean age of 54.5 years (range 28-76). Eight of the dissections were performed for lower lip cancer, 7 for tongue cancer, and 5 for floor of the mouth cancer. Sentinel lymph node biopsy was used to detect metastatic lymph nodes. Tc99m radionuclide injection was administered to the periphery of the tumor 24 h before the operation, and a lymphoscintigraphy image was obtained 30 min after the injection. Sentinel lymph nodes were localized and excised on the day of surgery using static lymphoscintigraphy images and a gamma probe. Sentinel lymph nodes were sent for a frozen section examination, and either a selective or a comprehensive neck dissection was performed for each neck according to the results. Results After the final histopathological examination of the specimens, the negative predictive value, the positive predictive value, the accuracy of the sentinel lymph node biopsy, and frozen section accuracy were found to be 100%. Conclusion Sentinel lymph node biopsy was found to be an efficient method in the pathological staging and management of the N0 neck in early T-stage oral cavity cancers.

Migration of a Swallowed Blunt Foreign Body to the Neck

Ingestion of foreign bodies is a common problem in the otolaryngology practice. Reports of extraluminal migration of the foreign bodies from the upper aerodigestive tract are rare. Penetration and extraluminal migration of ingested foreign bodies may cause severe vascular and suppurative complications, even death. We report a 4-year-old girl who presented with a mass and partial extrusion of a foreign body in the neck. She had a history of ingesting the plastic top piece of a knitting needle approximately 1 year ago. She had been asymptomatic until the present time. The examination revealed a red, blunt, rectangular plastic foreign body half embedded in the skin of the right neck. Esophagography with barium swallow, cervical X-rays, and computed tomography scans were obtained. The foreign body was easily removed under general anesthesia. Primary closure and direct laryngoscopy was also performed. The patient recovered very well without any complications.
