ABSTRACT
Abstract Introduction In sphenoid sinuses with ill-defined carotid bony landmarks, accidental injury of the internal carotid artery (ICA) remains one of the most challenging complications, which is particularly reported in the endoscopic endonasal transsphenoidal approaches (EETAs). Objectives To describe an anatomical model for the endoscopic orientation of the juxta-pituitary segment of the ICA in relation to the lateral opticocarotid recess (OCR) as a nearby bony landmark. Methods Dissection was performed progressively, simulating the EETA, in twenty fresh adult cadavers. After reducing the posterior and lateral walls of the sphenoid sinuses, various measurements were taken from both lateral OCRs to "contact points" on the juxta-pituitary segment of the ICA and lateral margins of the pituitary gland. Results The current results have enabled us to divide the region between the lateral OCRs into 3 compartments: 2 lateral parasellar compartments contain juxta-pituitary segments of the ICA with a mean width of 8 mm and a narrow range from 7 mm to 10 mm; and a central intercarotid sellar compartment represents the safe region for bone drilling, showing widely variable widths ranging from 9 mm to 20 mm. In all specimens, the variation in the width of the intercarotid compartment correlated with the distance between both lateral OCRs. Conclusion The present study improves surgeon awareness of the variations in the course of the ICA through the EETA along sphenoid sinuses with ill-defined bony landmarks. An appreciation of the measurements taken in the present study can help in operative training, and can also provide a base for future studies to confirm ICA courses associated with a higher risk of injury.
ABSTRACT
Pituitary adenoma is one of the most common intracranial tumors, and most of them can be well removed by endoscopic transsphenoidal surgery. Pituitary adenoma is located in the sella, which can compress the pituitary and optic nerve, invade the sphenoid sinus and cavernous sinus, invade and grow in all directions, and affect the endocrine function at the same time. Endoscopic transsphenoidal pituitary adenoma resection (EETS) has the advantages of minimally invasive, close observation, panoramic view, high tumor resection rate and high preservation rate of normal pituitary function, but it can cause pituitary endocrine disorder, diabetes insipidus, electrolyte disorder, cerebrospinal fluid leakage, intracranial infection, cerebral nerve paralysis, tumor cavity, intracranial hemorrhage, rhinitis and other related complications. It affects the prognosis and quality of life of patients. The postoperative complications of EETS are not only related to the pathophysiological characteristics of pituitary adenoma, but also closely related to the depth of understanding of pathology and anatomy of pituitary adenoma, surgical skills, proficiency and clinical experience. Familiarity with endoscopic anatomy and fine surgical techniques, rich surgical experience, strict preoperative endocrine function evaluation, hormone replacement therapy, etc. can reduce the incidence of postoperative complications of EETS.
ABSTRACT
Objective:To analyze the clinical outcome of nasal symptoms in patients with pituitary lesions after transsphenoidal surgery by microscope.Methods:A perspective study was performed; 53 patients with pituitary lesions treated by transsphenoidal microsurgery in our hospital from March 2012 to January 2013 were enrolled. Sinonasal outcome test (SNOT)-22 was used to evaluate the nasal symptoms in these patients before surgery, and 1 week, 1 month and 4 months after surgery; Toyota and Takagi (T&T) olfactometer was used to evaluate the olfaction before surgery, and 1 week and 4 months after surgery.Results:Among the 53 patients, 47 were with pituitary adenoma and 6 were with Rathke cysts. The common postoperative nasal symptoms included olfactory disorder, nasal obstruction, runny nose, pain in the nasal cavity and dizziness. The total scores and 5-items scores of SNOT-22 in patients 1 week and 1 month after surgery were significantly higher as compared with those before surgery ( P<0.05); there were no significant differences in these scores between before surgery and 4 months after surgery ( P>0.05). The incidence of olfactory disorder in patients 1 week and 4 months after surgery was significantly higher than that before surgery ( P<0.05); the incidence of olfactory disorder in patients 4 months after surgery was decreased as compared with that 1 week after surgery, without significant difference ( P>0.05). Conclusion:Olfactory disorder can occur to some extent after transsphenoidal approach with slow recovery, which deserves the attentions.
ABSTRACT
Pituitary adenoma is one common type of intracranial tumors, accounting for about 10% of intracranial tumors. Although pituitary adenomas are benign tumors, the complete resection and recurrence prevention remain challengeable due to aggressive growth of tumor, limited equipment conditions and surgical techniques of the surgeon. The proportion of recurrent pituitary adenomas is rising year by year and the difficulty of treatment also increases. This article reviews the diagnosis and treatment of recurrent pituitary adenomas based on the summary data of invasive or recurrent pituitary adenomas cases in our center, including indication for the second transsphenoidal surgery, surgical techniques, and prevention and treatment of postoperative complications, to provide reference for clinicians in this field.
ABSTRACT
El glioma del nervio óptico es una entidad de muy baja incidencia en pacientes adultos, lo cual impide tener suficiente información sobre historia natural y conducta terapéutica en este grupo etario. En el presente artículo comunicamos el caso de un paciente de 27 años de edad con compromiso agudo del nervio óptico izquierdo debido a hemorragia intra tumoral, forma de presentación muy poco común en este tipo de tumores. Se realizó la resección mediante un abordaje endoscópico transesfenoidal extendido, con preservación funcional de la vía óptica contralateral. La anatomía patológica confirmó astrocitoma pilocítico positivo para el rearreglo KIAA 1549-BRAF. y negativo para la mutación BRAF V600E. Teniendo en cuenta la histopatología y biología molecular en este caso, la estabilidad visual contralateral y la resección quirúrgica amplia, se decidió no realizar tratamiento adyuvante con radioterapia o quimioterapia. El objetivo de esta conducta fue evitar lesiones adicionales sobre el quiasma, nervio óptico contralateral y/o hipotálamo. Dada la escasa información existente en la literatura médica, el reporte de este caso podría contribuir con información adicional en el manejo y conducta terapéutica de este tipo de lesiones.
The optic nerve glioma is a very uncommon entity in adult patients, with little information about its natural history and therapeutical management. We report the case of a 27-year-old patient with acute involvement of the left optic nerve due to intratumoral hemorrhage, a very uncommon form of presentation in this type of tumor. Resection was performed using an extended transsphenoidal endoscopic approach, with functional preservation of the contralateral optic pathway. The histopathology confirmed positive pilocytic astrocytoma with KIAA 1549-BRAF rearrangement and without BRAF V600E mutation. Considering the histopathology and molecular biology, the contralateral visual stability and the wide surgical resection, it was decided not to perform further treatment. The purpose of this decision was to avoid additional damage to the chiasm, contralateral optic nerve and/or hypothalamus. Given the limited data available in medical literature, the report of this case could contribute with additional information on the management and therapeutic approach of this type of tumors

ABSTRACT
BACKGROUND AND OBJECTIVES: The conventional transseptal transsphenoidal approach can inhibit visualization of the surgical field and may change the shape of external nose. We used the transseptal transsphenoidal technique to remove septal cartilage except the L strut via a modified Killian's incision and preserved the ‘key-stone area.’ The aim of this study was to verify the usefulness of this technique. SUBJECTS AND METHOD: Retrospective analysis was carried out on 42 pituitary tumor patients who received this technique by a single otolaryngologist from March 2005 to March 2012 at Kangbuk Samsung Hospital. RESULTS: The mean patient age at time of surgery was 52 years, and 41 cases were pituitary adenoma and 1 was Rathke's cleft cyst. Three patients had undergone prior surgery; of which 2 used a pterional approach and 1 a transsphenoidal approach. With regard to complication, there were 2 cases of CSF leakage and 5 cases of septal laceration. There were no cases of meningitis, deformity of external nose, septal perforation, anosmia, or sinusitis. In post operation follow up, 25 cases (59.5%) had no residual tumor, while 17 cases (40.5%) had residual tumor. CONCLUSION: This study reveals that transseptal transsphenoidal surgery with septal cartilage removal and a replacement technique for a pituitary tumor are effective, allow easy exposure, and result in a low complication rate.

ABSTRACT
Objetivo: Aportar valores teóricos promedio de referencias anatómicas en tomografía computada con el fin de optimizar los abordajes transesfenoidales a la base de cráneo. Materiales y Métodos: Se desarrolló un diseño descriptivo, prospectivo, transversal y observacional de cien estudios de tomografía computada de macizo facial y base de cráneo. Mediante planillas de registro diseñadas ad Hoc, se confeccionó la base de datos considerando: sexo, edad, línea media, posición del rostrum esfenoidal y de la silla turca, posición de los ostium esfenoidales, presencia de las paredes óseas del seno esfenoidal, distancia entre las arterias carótidas internas y los nervios ópticos, neumatización de los recesos óptico-carotídeos, neumatización del seno esfenoidal, dimensiones del seno esfenoidal, número de tabiques intra-seno esfenoidal y su sitio de inserción posterior. Resultados: El rostrum esfenoidal es el mejor reparo de línea media para los abordajes transesfenoidales a la región selar. Los tabiques internos no deben considerarse como reparos de línea media seguros. Los ostium esfenoidales se localizan laterales a la línea media y conforman un sitio seguro para iniciar la apertura de la pared anterior del seno esfenoidal. Las paredes óseas laterales del seno esfenoidal no siempre están presentes a nivel de las prominencias carotídeas y ópticas. El canal de trabajo para abordar la silla turca está determinado por la distancia entre ambas arterias carótidas internas, siendo en promedio de 11,24 mm. Conclusión: La tomografía computada permite obtener un conocimiento de la anatomía del seno esfenoidal preciso para la planificación de un abordaje transesfenoidal a la silla turca o extendida a la base de cráneo.
Objective: To provide average theoretical values for anatomic references in computed tomography (CT) images and, thereby, improve the transsphenoidal approach to the skull base. Methods and Materials: A descriptive, prospective, cross-sectional, observational study was conducted of 100 CT evaluations of facial bones and the skull base. A database was created using ad hoc registration forms, entering data on patient gender and age, midline, position of the sphenoid rostrum, position of the sella, position of the sphenoid ostium, presence of the bony walls of the sphenoid sinus relative to the carotid and optic prominences, distance from the internal carotid arteries, distance between the optic nerves, pneumatization of the optic-carotid recesses, pneumatization of the sphenoid sinus, dimensions of the sphenoid sinus, and the number and posterior insertion sites of sphenoid septa. Results: The sphenoid rostrum was found to be the best midline reference for transsphenoidal approaches to the sellar region. Internal septa should not be considered safe midline references. The sphenoid ostium are located laterally to the midline, and are a safe site at which to initiate the opening of the anterior wall of the sphenoid sinus in the mid-caudal direction. The lateral bony walls of the sphenoid sinus are not always present at the carotid and optic prominence levels. The working channel to approach the sella is determined by the distance between the internal carotid arteries, the average distance being 11.24 mm. Conclusions: Computed tomography reveals the anatomy of the sphenoid sinus and sellar region and, thus, facilitates the trans-sphenoidal approach to the skull base.

ABSTRACT
Objective To explore the fast-track surgery (FTS) strategy in microscopic resection of pituitary adenomas using a single-nostril transsphenoidal approach. Methods The clinical data of 88 patients with pituitary adenomas, admitted to and underwent microscopic surgery using a transsphenoidal approach in our hospital from June 2015 to December 2017, were retrospectively analyzed. Only one nostril was used during surgery through a transverse incision in the nasal septum; the middle turbinates and nasal septum were not resected, and only the anterior wall of the sphenoidal sinus was removed; fenestration of the mucosa at the sellar floor was conducted; no hemostatic material was used to fill the sphenoidal sinus cavity, and the sphenoidal sinus drainage tube was retained. Four months after surgery, the modified Chinese version of 22-item Sino-nasal Outcome Test (SNOT-22) was used to evaluate the postoperative nasal complications and quality of life of the patients. The experiences with FTS strategy through microscopic resection of pituitary adenomas using a single-nostril transsphenoidal approach were summarized. Results The complete tumor resection rate was 65.90％ (58/88), near total resection rate was 12.50％ (11/88), subtotal resection rate was 19.32％ (17/88), and partial resection rate was 2.27％ (2/88). No such complications, as nasal septum perforation, delayed epistaxis, or internal carotid artery injury, were observed. Of the 88 patients, 32 were lost to follow-up; the 56 patients who reported for follow-up were evaluated in accordance with modified Chinese version of SNOT-22: 8 (14％) had a total scores>10; the mean highest and lowest scores for the various items were 0.02 (purulent nasal discharge) and 0.88 (hyposmia), respectively; most items had scores of 0-0.3. The postoperative discomfort experienced by the patients mainly included hyposmia, dizziness, head and facial pain or pressure, fatigue, and nasal congestion. Among the 56 patients, there were 26 with hyposmia, including 10 with mild hyposmia, 9 with moderate hyposmia and 7 with severe hyposmia. Conclusion Application of FTS reduces the incidence of nasal complications, and increases the postoperative comfort of patients in protecting the normal tissue structure in the nasal cavity for patients with pituitary adenomas.
ABSTRACT
Objective To observe the effect of flexible laryngeal mask (FLMA) in transnaso-sphenoidal microsurgery for pituitary adenoma on airway management and variation of stress response.Methods One hundred patients (71 males, 29 females, aged 18-65 years, BMI 21-28 kg/m2, ASA physical status Ⅰ or Ⅱ) undergoing transnaso-sphenoidal microsurgery for pituitary adenoma were randomly divided into two groups: the FLMA group (group F) and the reinforced endotracheal tube group (group T) using a random number table, 50 cases in each group.The plasma concentration of epinephrine and norepinephrine were measured before anesthesia induction (T0), at the time of inserting the FLMA or reinforced endotracheal tube (T1), 1 min (T2) and 5 min (T3) after insertion.The Berry scores of the preoperative and postoperative airway exposure by branchofiberoscope in group F were assessed.The time of removal of FLMA (endotracheal tube) and the occurrence of choking, laryngeal spasm, sore throat, hoarseness and other adverse reactions were recorded.Results The levels of epinephrine and norepinephrine were were significantly lower at T2 and T3 in group F than those in group T (P<0.05).There was no significant difference in airway Berry scores.The time of extubation was shorter in group F than that in group T [(9±3) min vs (17±6) min] (P<0.05).The incidence of choking (2% vs 22%) and sore throat (4% vs 30%) were significantly lower in group F than those in group T (P<0.05).Conclusion Compared with the reinforced endotracheal tube, FLMA can be applied safely and effectively to transnaso-sphenoidal microsurgery for pituitary adenoma, reduces stress respond associated with anesthesia and post-extubation complications, improves the recovery of patients.
ABSTRACT
Objective To discussion the effect of endoscopic single nostril transsphenoidal pituitary tumor resection on improving clini-cal symptoms and related quality of life of patients. Methods Selected 114 cases of patients with pituitary tumors in our hospital from August 2013 to August 2015, and randomly divided them into the nasal endoscopic group and the microscopic group according to the random number table,with 57 patients in each group. Patients of the 2 groups were treated with nasal endoscopic and microscopic single nostril transsphenoi-dal pituitary tumor resection respectively. The operation situation,hormone decline,incidence of complications after surgery and SNOT-20 and VAS score of the two groups were compared. Results Operative time of nasal endoscopic group was significantly higher than that in the mi-croscopic group,whlie the blood loss,length of hospital stay in endoscopic group was significantly lower than the microscopic group,and the difference was statistically significant (P0. 05). One week after operation,cerebrospinal fluid cell count,cerebrospinal fluid protein,adrenocorticotropic hormone,serum chloride,sodium, growth hormone,and prolactin levels of the nasal endoscopic group were lower than the microscopic group (P<0. 05). The complication rate was 14. 9% in the nasal endoscopic group,which was obviously lower than 59. 6% in the microscopic group (P<0. 05). One week after operation,the SNOT-20 scores and VAS scores were increased in both of the two groups,but the microscopic group increased more significantly (P<0. 05). Conclusion Endoscopic single nostril transsphenoidal pituitary tumor resection surgery cost longer operation time,but it lead to less trauma and less postoperative complications,which may delay the decline of patients’ quality of life and promote the improvement of prognosis.

Cushing's disease (CD) is a rare disorder characterized by the overproduction of adrenocorticotropic hormone due to a pituitary adenoma that ultimately stimulates excessive cortisol secretion from the adrenal glands. Prior to the detection of pituitary adenomas, various clinical signs of CD such as central obesity, moon face, hirsutism, and facial plethora are usually already present. Uncontrolled hypercortisolism is associated with metabolic, cardiovascular, and psychological disorders that result in increased mortality. Hence, the early detection and treatment of CD are not only important but mandatory. Because its clinical manifestations vary from patient to patient and are common in other obesity-related conditions, the precise diagnosis of CD can be problematic. Thus, the present set of guidelines was compiled by Korean experts in this field to assist clinicians with the screening, diagnoses, and treatment of patients with CD using currently available tests and treatment modalities.
