The Relationship of High Septal Deviation, the Depth of Olfactory Fossa, and Gera Angle: Is High Septal Deviation Associated With Any Anatomic Abnormalities in the Anterior Skull Base?

OBJECTIVE: To investigate the association of high septal deviation with the olfactory fossa depth and Gera angle. METHODS: Fifty-four computed tomography scans of patients with high septal deviation were evaluated. The olfactory fossa depth and Gera angle were measured. The values of the deviated and nondeviated sides were compared. RESULTS: No association between high septal deviation and the olfactory fossa depth and Gera angle was found. CONCLUSION: High septal deviation does not affect the olfactory fossa depth and Gera angle. In other words, the olfactory fossa depth and Gera angle have no association with the high septal deviation.

Effects of Expansion Sphincter Pharyngoplasty on the Apnea-Hypopnea Index and Heart Rate Variability.

PURPOSE: Heart rate variability (HRV) is a noninvasive and sensitive method used to evaluate autonomic function of the heart based on specific polysomnographic parameters. This study aimed to determine the effect of expansion sphincter pharyngoplasty (ESP) on HRV and the apnea-hypopnea index (AHI) in patients with obstructive sleep apnea (OSA). MATERIALS AND METHODS: This retrospective cohort study included patients who presented to the Department of Otorhinolaryngology, Hacettepe University Hospital (Ankara, Turkey), were diagnosed with OSA, and underwent ESP. Patient medical records, including demographic data, polysomnographic findings, and HRV parameters, were reviewed. The predictor variable was the effect of ESP on the AHI and the primary outcome variables were HRV parameters. Descriptive and bivariate statistics were computed using χ2 test, t test, and Mann-Whitney U test. RESULTS: The mean age of the 28 patients (20 men and 8 women) was 43 ± 9.9 years. Surgical success (AHI, <20; 50% decrease in the AHI) was achieved in 16 patients (57.1%). The AHI decreased in 22 patients (78.6%) but increased in 6 patients (21.4%) after ESP. The ratio of low-frequency power (LF) to high-frequency power (HF) decreased significantly in the patients with successful surgery and in those whose AHI decreased after surgery (P = .02 and P = .001, respectively). For the change in the LF/HF ratio, 19 patients had a decrease in sympathetic activity, whereas 9 had an increase in sympathetic activity, after ESP. A decrease in sympathetic activity after ESP was significantly associated with surgical success and a decrease in the AHI (P = .033 and P = .001, respectively). CONCLUSION: ESP is an effective surgical option for the treatment of OSA and lowers the AHI. Successful ESP plays a role in decreasing sympathetic activity of the heart, which might be associated with a decrease in the risk of cardiovascular disease.

Two consecutive cases of cerebrospinal fluid rhinorrhea after septoplasty operation.

Our aim in this work is to define the importance of anatomical knowledge in septoplasty operation and to prevent complications. Septoplasty is one of the most common operations in otorhinolaryngology to treat the nasal obstruction caused by septal deviation. During and after septoplasty, there are some recorded complications, such as hemorrhage, hematoma, septal abscess, septal perforation, saddle nose, infection, anosmia, visual disturbances, cavernous sinus thrombosis, meningitis, pneumoencephalos, subarachnoid hemorrhage, subdural empyma, brain abscess, periorbital emphysema, toxic shock syndrome, and cerebrospinal fluid (CSF) rhinorrhea. Some of the complications are rare, but their results are life threatening. We report a rare complication of septoplasty CSF rhinorrhea. Two consecutive cases of CSF fistulas after septoplasty operation are presented. Both of the cases were treated endoscopically. The possible mechanisms and different treatment options are discussed. Prevention of the CSF fistula in septoplasty is more important than its treatment. Realizing the anatomic variations and gentle manipulation at the ethmoid roof is essential.

Endoscopic surgery in treatment of juvenile nasopharyngeal angiofibroma.

OBJECTIVES: Juvenile nasopharyngeal angiofibroma (JNA) is a highly vascular and locally invasive tumor with a high incidence of persistence and recurrence. The classical treatment of this tumor is surgery and/or radiotherapy. Use of endoscopic techniques seems to be on the rise in treatment of these lesions. We tried to explore the roles and limits of endoscopic surgery alone or with classical surgical techniques in treatment of these tumors. METHODS: Retrospective case review was conducted at a tertiary referral center. Twelve patients were treated for nasopharyngeal angiofibroma using endoscopic approach between 1998-2002. The staging, average blood loss during surgery, residual, and/or recurrent tumor were evaluated. RESULTS: Eight of these patients (8/12) were up to stage IIC according to Radkowski staging. This group of patients has an average blood loss of 1000 ml and were followed for at least 6 months. We did not encounter any residual or recurrent tumor in this group. Four patients (4/12) had minimal intracranial extension, were staged IIIA, and had an average blood loss of 1500 ml during surgery. Two of these patients had minimal residual tumor around the cavernous sinus, but showed no progression of disease over a follow-up of 2 years with MRI. Two patients had no residual or recurrent tumor over a follow-up of 6 months. CONCLUSION: This data suggests that endoscopic surgery can be used in the treatment of JNA even with minimal intracranial extension with minimal morbidity and low recurrence rate.
