Applied anatomy for pituitary adenoma resection / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Pituitary adenomas are common intracranial tumors, with a rising incidence in China. Excision is a mainstay therapy for this disease, and is often carried out via transfrontal, transsphenoidal or transpterional approaches. However, few studies have systematically addressed the regional anatomy involved in these microsurgical procedures. The present study attempted to establish some key anatomic measurements relevant to pituitary adenoma resection based on cadaver and computer tomography (CT) image studies.</p><p><b>METHODS</b>Head specimens from 30 randomly selected formalin-fixed adult cadavers were used for anatomical analysis. Measurements were made on the base of the skull following removal of brain structures above the pituitary gland, and on the mid-sagittal plane of the cranium. Parameters were designed by considering the 3 above-mentioned common microsurgical approaches, and obtained on each head using a sliding caliper. Multi-level CT images from 30 individuals were also used for distance measurements between landmark structures that are relevant to these surgeries. All data were subjected to statistical analysis using the SPSS 11.5 software.</p><p><b>RESULTS</b>There was statistically significant difference (P < 0.05) of distance measured on cadavers relative to CT images in 3 sets of measurements related to the transfrontal surgical approach, i.e., distances from the midpoint of superciliary arch superior border to the cranial entrance of internal carotid arteries (ICAs), the opposite side entrance of ICA and to the genu of ICA. While regional anatomical analyses were carried out according to the transpterional approach, statistically significant difference was also found in 3 sets of distance measurements between cadaver and CT image data, with regard to the distances between the pterion and some landmark structures around the pituitary.</p><p><b>CONCLUSIONS</b>The present study provides key anatomical and CT image measurements involving the 3 conventionally used surgical approaches for pituitary tumor resection. The data implicate that while CT scan results can provide valuable guidelines for operations, cautions and adjustments are needed during surgery for sufficient tumor excision and protection of key blood vessels and nerves in the vicinity of the pituitary gland and around the surgical pathway.</p>

Surgical treatment of childhood craniopharyngioma: clinical analysis of 31 cases / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To study the diagnosis, surgical treatment and outcome of craniopharyngioma in 31 children.</p><p><b>METHODS</b>The clinical data of 31 children (aged 7-14 years) with craniopharyngioma were studied retrospectively.</p><p><b>RESULTS</b>Headache, visual disorder and growth retardation were main manifestations in the 31 children. The 31 children were definitely diagnosed with craniopharyngioma by CT and MRI. In the 31 cases, 19 (61.3%) underwent total tumor removal, 5 (16.1%) subtotal removal, and 7 (22.6%) partial removal. After tumor removal, transient diabetes insipidus occurred in 19 cases (61.3%) and long-term diabetes insipidus in 3 cases. Six cases (19.4%) presented hypothalamic injuries after surgery. No patient died after surgery. Five patients (16.1%) had recurrent tumor in a mean follow-up of 32.5 months.</p><p><b>CONCLUSIONS</b>The diagnosis of childhood craniopharyngioma may be based on clinical manifestations and CT/MRI examinations. Craniotomy is a preferred surgical treatment. Proper extent of tumor resection should be determined in order to reduce the tumor recurrence and the incidence of postoperative complications.</p>

Observation on therapeutic effect of comprehensive therapy on optic atrophy complicated by cerebral palsy / 中国针灸

<p><b>OBJECTIVE</b>To assess therapeutic effect of combined treatment of Chinese medicine and western medicine on optic atrophy complicated by cerebral palsy.</p><p><b>METHODS</b>One hundred and seventeen cases were divided into an observation group (n = 79) and a control group (n = 38). The control group were treated with routine western medicine treatment including neurotrophic drugs and high pressure oxygen, etc. and the observation group with acupuncture at Ganshu (BL 18), Pishu (BL 20), Chengqi (ST 1), etc. and injection of 0.2-0.3 mL Compound Danshen Injectio into Qiuhou (EX-HN 7), on the basis of the same treatment of western medicine as that in the control group. Fundus examination and the tracing body angle detection were conducted before and after treatment and the therapeutic effects were assessed in the two groups.</p><p><b>RESULTS</b>The total effective rate was 91.1% in the observation group and 60.5% in the control group with a significant difference between the two groups (P < 0.001); after treatment the angle of tracing body significantly increased in the two groups (P < 0.01) with the observation group better than the control group (P < 0.01).</p><p><b>CONCLUSION</b>The combined treatment of Chinese medicine and western medicine is an effective therapy for optic atrophy complicated by cerebral palsy.</p>

Mononostril-septum-transsphenoidal approach for pituitary adenoma / 中南大学学报(医学版)

OBJECTIVE@#To summarize the mononostril-septum-transsphenoidal approach for pituitary adenoma.@*METHODS@#The clinical features, operative techniques, and outcome of 36 patients with pituitary adenoma were analyzed retrospectively.@*RESULTS@#Tumors were totally removed in 28 cases, and subtotally resected in 8 patients. No patient died after the operation. Endocrine symptom of 31 patients returned to the normal level, the symptom of the other 5 cases were improved. Thirty patients with visual field defects recovered after the operation. Cerebrospinal fluid leakage occurred in one patient, and was cured with conservative treatment in 2 weeks.@*CONCLUSION@#Mononostril-septum-transsphenoidal approach can make use of the natural space of the nasal cavity, which has many advantages, such as direct approach, short operative time, minimal invasion, and few complications. It is a effective transsphenoidal surgical approach.
