The latissimus dorsi myocutaueous flap. Its use in reconstructive surgery. Servant JM, Banzet P (1983) Chirurgie 109:223~44

The latissimus dorsi myocutaneous flap is one of the most fre- quently used flaps to achieve surgical repair of extensive tissue loss. The authors underline the vascularization of the latissimus dorsi by the subscapular pedicle and the arterial supply to the overlying cutaneous area by direct cutaneous branches or per- forating arteries originating from the subjacent muscles.

Anomolous emergence of the lumbosacral radicular sheaths: mye- lographic diagnosis and surgical applications. Babin G, Madge JL, Dietemann (1983) Ann RadioI 26:295 305

The authors analysed 45 cases of abnormal emergence of the lumbosacral radicular sheaths as seen on myelography. The main anomaly was a common radicular sheath most often in- volving the L5---$1 roots. The identification of such anomalies seems to be of special importance, notably by allowing to adapt the surgical approach and technique. M Fernet

Anomalies of the inferior vena cava. Mayo J, Gray R, Saint Louis E, Grosman H, McLoughlin M, Wise D (1983) AJR 140:339-345

Based on a series of 12 cases the authors present the embryology and a review of the main anomalies of the inferior vena cava as seen on computed tomography of the abdomen or angiogra- phy. This study confirms the significance of computed tomogra- phy to identify the subdiaphragmatic vascular structures.

The N M R images were compared to those obtained by com- puted tomography and to anatomical sections of the region. Although the definition of the N M R images is of poorer quality compared to those offered by recent CT scanners, N M R is advantageous with respect to the identification of blood vessels and lymph nodes and allows to determine the type of tissue imaged.

High-resolution computed tomography of the middle ear and mas- toid: Part I. Normal radioanatomy including normal variations. Swartz JD (1983) Radiology 148: 449-454

Computed tomography of the middle ear and mastoid yields images far superior to those obtained in the past by polytomog- raphy. The walls of the middle ear, the ossicula auditus and their attachments, the tympanum and the air cavities of the mastoid are shown in remarkable detail in this work, the first part of which is devoted to the normal radioanatomy and varia- tions of the middle ear.

Inferior pulmonary ligament: Computed tomographic appear- ance. Rost RC, Proto AV (i983) Radiology 148:479-483

This work is a retrospective study o f / 2 9 CZ procedures of the thorax re-examined in order to identify the appearance and frequency of the inferior pulmonary ligament. The ligament was observed on the left side in 67.4% of subjects, on the right in 37.2% and bilaterally in 27.1%. It was not visualized in 22.4% of cases. Post mortem dissections were used to describe the traditional anatomy of this ligament. JPC

Computed tomography of the nasopharynx and related spaces. Part I: Anatomy. Silver AJ, Mawad ME, Hilal SK, Sane P, Ganti SR (1983) Radiology 147:725-731

The authors present a computed tomography study of the naso- pharynx and pterygopalatine region. The classical anatomy is presented my means of illustrations and traditional anatomical sections. The authors then compare these data to CT cuts which allow to distinguish the muscles of deglutition and mastication. The relations between the muscles of the soft palate and those of the Eustachian tube are described in detail. JPC

lowed by computed tomography. The main interest of this tech- nique is to demonstrate the plica mediale which often goes unseen on standard arthrography. The authors report a high incidence of this fold (47% of cases) greatly exceeding that commonly reported in the literature (e.g. 25% of cases accord- ing to a recent study by Jouanin et al. published in 1982 in Anatomia Clinica, Vol. 4, Number l). This apparently elevated frequency of occurrence seems to be related to the finesse of the CT imaging which allows to demonstrate extremely thin plicae. JPC

Nuclear magnetic resonance imaging of the thorax. Gamsu G, Webb WR, Sheldon P, Kaufman L, Crooks LE, Birnberg FA, Goodman P, Hinchcliff WA, Hedgecock M (1983) Radiology 147: 473-480

Ten normal thorax were studied by nuclear magnetic resonance yielding images comparable to those obtained by computed tomography. The hili are particularly well demonstrated by NMR. JPC

Work in Progress: Nuclear magnetic resonance imaging of the Gallbladder. Hricak H, Filly RA, Margulis AR, Moon KL, Crooks LE, Kaufman L (1983) Radiology 147:481-484

Computed tomography of the articulations and ligaments at the occipito-atlantoaxial region. Daniels DL, Williams AL, Haughton VM (]983) Radiology 146:70%716

This anatomical study is based on post mortem dissections and computed tomography of the suboccipital joints. The bony structures and their means of union are easily identified on the CT cuts, the interpretation of which is facilitated by the post mortem dissections and the classical anatomical data pre- sented.

The caudate lobe (Spiegelius'lobe) of the liver. Anatomical study and surgical applications. Foucou B, Ould Said H, Joyeux A, M'Jahed A, St Aubert B, Hamdouch Z, Joyeux H, Solassol CL (1983) Chir (Paris) 120:]7%186

The authors present a study of 28 anatomical preparations (dis- section and plastic casting) allowing to investigate the caudate lobe, also known as Spiegel]us' lobe, the dorsal segment or Couinaud's segment I of the liver. The first part of this study presents the anatomy.~f this lobe including its surface morphol- ogy and vasculobiliary distribution. The second, more clinical part, describes the investigative procedures and surgery of this segment of the liver. JPC

Anatomical difficulties in the dissection of the recurrent laryngeal nerve. Flament JB, Delattre JF, Palot JP (]983) J Chit (Paris) 120:32%334

Based on a series of 100 anatomical dissections and their experi- ence of 600 surgical procedures on the thyroid the authors de- scribe the main difficulties encountered on dissection of the

recurrent laryngeal nerve in relation to its anomalies and varia- tions. Successively studied are its variations with respect to the termination of the inferior thyroid artery and the extralaryngeal bifurcations of the nerve. The last part of this paper is devoted to non recurrence of the inferior laryngeal nerve. JPC

Speech, laryngeal nerve and thyroid surgery. Anatomical and clin- ical study. Results of a homogeneous series of 378 operations. Paineau J, Hingrat JY, Lehur PA, Visset J (1983) Chir (Paris) 120: 367-372

Based on a series of 378 cases of thyroidectomy the authors describe the anatomy of the inferior laryngeal and external la- ryngeal nerves with reference to their studies presented at the Congr6s de l'Association des Anatomistes in 1972 and 1975.

Vascular segmentation of the spleen in the newborn. Anatomical support for partial resection. Mandarin-Lacerda CA, Sampaio FJB, Passos MA (1983) J Chir (Paris) 120:471~473

This work is based on the study of 66 arterial casts of the spleen removed from stillborn babies. The mode of termination of the splenic artery in the hilus and its intraparenchymal distri- bution are analysed. The results of this study show that the segmentation of the neonatal spleen is similar to that of the adult organ, the former displaying 2 (68.2% of cases), 3 (10.6% of cases) or 4 (4,5% of cases) segments. In 16.7% of the cases studied intersegmental anastomoses were observed. As in the adult, partial splenectomy can be performed in the newborn owing to the existence of intraparenchymal segmentation.

Computed tomography of cervical and retropharyngeal lymph nodes: Normal anatomy, variants of normal, and applications in staging head and neck cancer. Part I: Normal anatomy. Man- cuso AA, Harnsberger HR, Muraki AS, Stevens MH (1983) Radiology 148:709-714

This paper is an anatomical study by computed tomography of the cervical lymph nodes and notably those in the retrophar- yngeal position. After presenting the classical anatomy the au- thors give an analysis of CT cuts in 30 subjects showing the site and size of these nodes. The results of this study are in agreement with these of the classical anatomical literature, thus demonstrating the reliability of CT in the radiological workup of inflammatory or tumoral lesions in the cervical region.

Anatomical basis for the surgical use of the cephalic vein (V. cephalica): 74 anatomical dissections, 189 surgical dissections. Lesaout J, Vall6e B, Person H, Doutriaux M, Blanc J, Nguyen Huu (1983) Chir (Paris) 120:131-134

This paper describes the work of the Laboratoire d 'Anatomie de Brest where 74 post mortem and 189 surgical dissections of the deltopectoral port ion of the cephalic vein were studied. In 80% of cases the vein displayed a classical anatomical pat- tern with a diameter sufficient to receive a 3 to 4 mm sound. Conversely, in 20% of cases the vein was of no surgical useful- ness since it was absent or too slender. This anomaly was most often a unilateral finding since a normal vein was observed on the opposite side in 2/3 of such cases. JPC

High resolution analysis of facial struts in trauma: normal anato- my. Centry LR, Manor WF, Turski PA, Strother CM (1983) AJR 140: 523-532

The authors studied facial anatomy by high resolution com- puted tomography allowing cuts 1.5 mm thick. Emphasis is giv- en to the relations between the main bony facial struts and the anatomical structures of the adjacent soft tissue. The very high definition of the CT images shown allows an extremely detailed analysis of all structures and an extensive evaluation of traumatic lesions. M Fernet
