RESUMEN

The aim of this study was to reveal the clinical importance of measurements taken from the pharyngeal tubercle (PT) to various anatomical structures around the extracranial clivus. Twenty-six adult dry Anatolian skulls were examined. The extracranial clivus and PT were used as landmarks from which various distances were measured using a digital caliper accurate to 0.01 mm. The following mean distances from the PT were observed; foramen lacerum (FL) (L: 17.15 mm, R: 17.4 mm) ; medial external margin of the carotid canal (CC) (L: 26.7 mm, R: 27.5 mm); anterior tip of occipital condyle (OC) (L: 16.4 mm, R: 16.3 mm); anterior margin of foramen magnum (FM) (10.8 mm); foramen ovale (FO) (L: 25.9 mm, R: 29.1); medial margin of the jugular fossa (JF) (L: 25.4 mm, R: 25.7 mm); medial external margin of the hypoglossal canal (HC) (L: 20.0 mm, R: 19.9 mm). Mean bilateral distances were: LFO-RFO: 45.34 mm; LFL-RFL: 20.1 mm; LCC-RCC: 52.1 mm; LOC-ROC: 17.6 mm; LJF-RJF: 45.2 mm; LHC-RHC: 33.5 mm. The following mean distances were observed from the FM: FM-OC (L: 8.3 mm, R: 9.3 mm); FM-HC (L: 17.8 mm, R: 17.4 mm). Also the mean distance of OC-HC were observed (L: 11.7 mm, R: 11.4 mm). Present measurements suggest that the PT can be used as an anatomical landmark during surgery involving clival pathology. However, the anatomy and variations of the extracranial clivus and surrounding structures must be taken into consideration.


El objetivo de este estudio fue revelar la importancia clínica de las mediciones tomadas desde el tubérculo faríngeo (TF) a diversas estructuras anatómicas alrededor del clivus extracraneal. Veintiséis cráneos, secos adultos, de Anatolia, fueron examinados. El clivus extracraneal y TF se utilizaron como puntos de referencia a partir de los cuales se midieron varias distancias con un calibrador digital con una precisión de 0,01 mm. Se observaron las siguientes distancias medias del TF: foramen lacerum (FL) (L: 17.15 mm, R: 17,4 mm); margen externo medial del canal carotídeo (CC) (L: 26,7 mm, R: 27,5 mm); parte anterior del cóndilo occipital (OC) (L: 16,4 mm, R: 16,3 mm); margen anterior del foramen magnum (FM) (10,8 mm); foramen oval (FO) (L: 25,9 mm, R: 29,1); margen medial de la fosa yugular (FY) (L: 25,4 mm, R: 25,7 mm); margen medial del canal hipogloso (CH) (L: 20,0 mm, R: 19,9 mm). Las distancias bilaterales medias fueron: LFO-RFO: 45,34 mm; LFLRFL: 20,1 mm; LCC-RCC: 52,1 mm; LOC-ROC: 17,6 mm; LJFRJF: 45,2 mm; LHC-RHC: 33,5 mm. Se observaron las siguientes distancias medias de la FM: FM-OC (L: 8,3 mm, R: 9,3 mm); FMCH (L: 17,8 mm, R: 17,4 mm). También se observó la distancia media de OC-CH (L: 11,7 mm, R: 11,4 mm). Las mediciones actuales sugieren que el TF puede ser utilizado como un hito anatómico durante la cirugía que involucra la patología clival. Sin embargo, se deben tener en cuenta la anatomía y las variaciones del clivus extracraneal y las estructuras circundantes.

RESUMEN

Objective:To investigate the diagnosis and therapy of space-occupying lesion of middle skull base involving sphenoid sinus.Method:A retrospective analysis was performed. Eighteen patients with extradural space-occupying lesion of middle skull base involving sphenoid sinus underwent transnasal endoscopic surgery.Result:One case of primary empty sella turcica was misdiagnosed as sphenoidal sinus cyst. One case of fibrous dysplasia and one case of meningioma were all misdiagnosed as mycotic sphenoiditis. Total rate of misdiagnosis was 16.7%.Among the 18 cases, 17 cases underwent complete resection of the lesion, and only 1 case underwent major resection of the lesion. The amount of blood loss during surgery ranged between 100 ml and 2500 ml.One case had bacterial meningitis which was cured after corresponding treatment. One case was blind in both eyes. And the other case died of pulmonary embolism.Conclusion:Transnasal endoscopic surgery is feasible and practical to treat benign space-occupying lesion of sphenoidal sinus and extradural lesion of middle skull base involving sphenoidal sinus. Definite diagnosis, accurate location and careful operation are important to complete the surgery successfully.

RESUMEN

Objectives: Inquirying the ability of the earlier diagnosis and studying the surgical management of intra and extra middle skull base tumors. Methods: A retrospective study has been made on 43 cases of malignant skull base tumor extended into cavernouse sinus. CT and MRI evaluation were made for all patients. Different approaches have been utilized to remove tumors. Results: In early period there was no obviously clinical sign. 5 year survival rate was 35.1%. Seven cases of no removing totally tumors in cavernous sinus had been alive for 7 months. Conclusions: The symptoms of skull base carcinoma is less, which often leads to false diagnosis and management. Total resection via different approaches may improve clinical results.
