The ectopic pancreas is rare abnormal anatomy. This paper introduced 4 cases of the ectopic pancreas, which had occurred when patients were fetuses. The ectopic pancreas mainly focused in the upper digestive tract. In generally, there were no symptoms. If have, the symptoms were various which depended on the position and size such as digestive bleeding, ileus, intussuseption and pancreatic pathology such as acute or chronic pancreatitis. The ectopic pancreas usually was diagnosed before operation. It should remove the ectopic pancreas if it is the pathogen.

INTRODUCTIONMultiple tendons of the abductor pollicis longus (APL) in the anatomical snuffbox of the wrist can lead to the development of de Quervain's syndrome, which is caused by stenosing tenosynovitis. A cadaveric study was performed to establish the variations present in the tendons of the anatomical snuffbox in a Malaysian population, in the hope that this knowledge would aid clinical investigation and surgical treatment of de Quervain's tenosynovitis.

METHODSRoutine dissection of ten upper limbs was performed to determine the variations in the tendons of the anatomical snuffbox of the wrist.

RESULTSIn all the dissected upper limbs, the APL tendon of the first extensor compartment was found to have several (3-14) tendon slips. The insertion of the APL tendon slips in all upper limbs were at the base of the first metacarpal bone, trapezium and fascia of the opponens pollicis muscle; however, in seven specimens, they were also found to be attached to the fleshy belly of the abductor pollicis brevis muscle. In two specimens, double tendons of the extensor pollicis longus located in the third extensor compartment were inserted into the capsule of the proximal interphalangeal joints before being joined to the extensor expansion. In two other specimens, the first extensor compartment had two osseofibrous tunnels divided by a septum that separated the APL tendon from the extensor pollicis brevis tendon.

CONCLUSIONMultiple variations were found in the anatomical snuffbox region of the dissected upper limbs. Knowledge of these variations would be useful in interventional radiology and orthopaedic surgery.

OBJECTIVE: To analyze the anatomical and developmental characteristics of nasal sinuses in 1-2 years old children; and provide potential evidence for the diagnosis and treatment of sinusitis in 1-2 years old children. METHOD: Coronal CT scans of 60 cases (1-2 years old children) were studied with the imaging station. Reference datas were identified on these images using imaging station. The gasification conditions of the sinuses were identified and measured. RESULT: 100% of the frontal sinuses were not developed, while 100% of the maxillary sinuses were developed. The mean of the transverse and vertical diameters for the left side of the maxillary sinuse was (13.32 ± 2.88) mm and (13.55 ± 2.43) mm, respectively. While those for the right side were (13.63 ± 2.75) mm and (13.59 ± 2.13) mm, respectively. The anterior and posterior ethmoid sinuses were 100% developed. The mean transverse and vertical diameters for the left side of the anterior ethmoid sinus were (3.94 ± 0.86) mm and (11.92 ± 1.67) mm, respectively. While those mean for its right side were (3.88 ± 0.88) mm and (12.18 ± 1.86) mm, respectively. The mean transverse and vertical diameters for the left side of the posterior ethmoid sinus were (6.02 ± 1.07) mm and (10.51 ± 1.43) mm, respectively. While those for the right side were (5.91 ± 1.20) mm and (10.51 ± 1.55) mm, respectively. 88.3% (106 sides) of the sphenoid sinuses were developed, while 11.7% (14 sides) were not developed. The mean transverse and vertical diameters for the left side of the sphenoid sinus were (5.18 ± 2.15) mm and (5.78 ± 1.86) mm, respectively. While those for the right side were (4.91 ± 2.24) mm and (5.89 ± 2.03) mm, respectively. CONCLUSION The nasal sinuses in 1-2 years old children have been already developed. The development of the maxillary and ethmoid sinuses was clear and definite. The pneumatization of the sphenoid sinus was defined in many babies; however, the pneumatization of the frontal sinus was not defined in all babies. Acute rhinosinusitis in 1-2 years old children is not uncommon. Therefore, definite diagnosis and positive treatment of such cases are essential for avoidance of serious complications.

OBJECTIVETo analyze the correlation between olfactory bulb(OB) volume with depth of olfactory sulcus (OS) and olfactory function in patients with idiopathic olfactory loss (IOL).

METHODSForty patients with IOL and forty normal controls were compared in terms of olfactory function T&T testing and magnetic resonance imaging (MRI, observation of OB volume and depth of OS). T&T testing and MRI were performed again after a year in 40 IOL patients, the results were compared with the first time.

RESULTSOB volume of left side in IOL patients was (30.31 ± 4.07) mm(3), right side was (30.82 ± 4.14) mm(3), average OB volume was (30.53 ± 4.10) mm(3); OB volume of left side in normal controls was (49.56 ± 7.19) mm(3), right side was (49.84 ± 7.25) mm(3), average OB volume was (49.73 ± 7.21) mm(3). OB volume was lower in IOL patients as compared to controls (t value were 8.122, 8.274, 8.231, all P < 0.01). OS depth study revealed no statistical different between IOL patients and controls (t value were 0.998, 1.017, 1.001, all P > 0.05). Olfactory discriminate threshold was negatively correlated with OB volume in IOL patients (r = -0.53, P < 0.05). There was no correlation with the depth of OS (r = -0.19, P > 0.05). Among 40 IOL patients, when followed-up, 12 showed increased in OB volume and olfactory function after a year, but no statistical difference was found with the first time (t value were 0.831, 0.864, 0.826, all P > 0.05). The other 28 patients showed no significant changes of OB volume and olfactory function.

CONCLUSIONSThe OB volume was lower in IOL patients as compared to normal controls. The depth of OS showed no significant changes in IOL patients. The OB volume was correlated with olfactory function. The depth of OS did not correlated with the olfactory function. Some IOL patients showed increased OB volume and improved olfactory function with the development of the disease.

Measurement of cervical lordosis is the basic method for evaluating cervical function, and important reference for determine treatment decision. However, how to choose appropriate measurement in accordance with different situation, as well as the relationship among these methods is not clear. An increasing number of studies suggested that different measurements could directly affect the judgment of cervical lordosis. Therefore, comparative study of cervical vertebrae plays an important role in clinical treatment for cervical spondylosis under different cervical curvature conditions.

INTRODUCTIONKnowledge of morphological variations of the suprascapular region is important in the management of entrapment neuropathy and interventional procedures. The objective of this study was to collect data on the morphological features and dimensions of ossified ligaments and unusual bony tunnels of scapulae from a North Indian population.

METHODSA total of 268 adult human scapulae of unknown gender were obtained from the bone bank of the Department of Anatomy, Dayanand Medical College and Hospital, Ludhiana, Punjab, India. The scapulae were evaluated for the incidence of ossified superior transverse scapular ligaments (STSLs), ossified inferior transverse scapular ligaments (ITSLs) and bony tunnels (i.e. the bony canal between the suprascapular notch and spinoglenoid notch), found along the course of the suprascapular nerve (SSN). The dimensions of these structures were measured and noted down. Ossified STSLs were classified based on their shape (i.e. fan- or band-shaped) and the dimensions of the ossified suprascapular openings (SSOs) were measured.

RESULTSOssified STSLs were present in 26 (9.7%) scapulae. Among the 26 scapulae, 16 (61.5%) were fan-shaped (mean area of SSO 16.6 mm(2)) and 10 (38.5%) were band-shaped (mean area of SSO 34.2 mm(2)). Bony tunnels were observed in 2 (0.75%) specimens, while an ossified ITSL was observed in 1 (0.37%) specimen.

CONCLUSIONThe data obtained in the present study augments the reference literature for SSN decompression and the existing anatomical databases, especially those on Indian populations. This data is useful to clinicians, radiologists and orthopaedic surgeons.

Anatomical variations are typically more common in the extensor compartment of the forearm, but uncommon in the flexor compartment. The presence of such anatomical anomalies is not usually noticed until the normal functions of an individual become hindered, or when these anomalies become a surgical problem. During routine dissection curriculum, we encountered a rare finding of bilateral Gantzer muscles in a cadaver. We describe the relationship between the Gantzer muscle and anterior interosseous nerve syndrome.

OBJECTIVE: To discuss the soft palate, hard palate and mandibule for the pathogenesis and clinical treatment of patients who have obstructive sleep apnea hypopnea syndrome. METHOD: There were 52 patients with OSAHS diagnosed by the PSG and 32 cases of normal healthy volunteers in our hospital. All objects were given 128 slice spiral CT scan of the upper airway. We measured the related indexes of the soft palate, hard palate and mandible, then analysed statistical differences between them and did Pearson correlation analysis with apnea hypoventilation index (AHI), average blood oxygen saturation (MSaO2) in PSG. RESULT: Compared with the control group, the soft palate length [(37.93 ± 5.20)mm VS (33.52 ± 4.25)mm] and the distance between mandible with cervical vertebra [(75.00 ± 7.10)mm VS (69.93 ± 5.58)mm] increased significantly, but the distance of trailing edge of hard palate to inferior margin of slope significantly reduced [(42.57 ± 4.52)mm VS (45.80 ± 2.94)mm, P < 0.01] in patients with OSAHS. Each measurement associated with AHI and MSaO2 had no significant correlation (P > 0.05). CONCLUSION The soft palate, hard palate and mandibular are some of the important risk factors of OSAHS, and they also have reference value for the choice of clinical treatment operation. Preoperative CT examination can offer help in the treatment of OSAHS.
