联合肩胛/肩胛旁分叶皮瓣修复严重颌颈部瘢痕挛缩

目的探讨临床应用联合肩胛/肩胛旁分叶皮瓣显微修复严重颌颈部瘢痕挛缩畸形,并重建颈部三维活动功能及轮廓外观的方法和疗效。方法2003年1月~2004年11月,收治9例严重颌颈部瘢痕挛缩畸形患者,年龄9~32岁。病程2~18年。瘢痕挛缩程度为3~4度。行瘢痕切除,对颈部挛缩组织松解复位所致软组织缺损创面采用联合肩胛/肩胛旁分叶皮瓣进行解剖分区的显微修复。分叶皮瓣范围最大分叶皮瓣为20cm×8cm~20cm×11cm,最小分叶皮瓣为15cm×4cm~15cm×6cm。结果9例患者有8例分叶皮瓣成活,1例肩胛皮瓣远端发紫,经换药加压包扎后成活。其中8例术后获3~9个月随访,畸形无复发,颌颈角恢复至90~105°;3例行二期皮瓣臃肿修整手术。患者对术后颌颈部外观和功能均满意。结论对于严重颌颈部瘢痕挛缩畸形,联合肩胛/肩胛旁分叶皮瓣可提供足够的组织覆盖,有可靠的血管蒂,对于重建颌颈部功能和外形,是一种较好的手术选择。

Computed tomography in gunshot wounds to the neck: Can we predict vascular injury?

The purpose of this study was to evaluate the ability of helical computed tomography (CT) to detect arterial injuries in gunshot wounds to the neck. In a blinded retrospective review, 54 helical CT scans of the cervical spine were evaluated for bullet/bone fragments, subcutaneous air, bullet path, hematoma, spine fractures, and pharyngoesophageal compromise. The distance of fragments to a major vessel was calculated. CT findings that correlated significantly with major arterial injury included the presence of fragments (bullet/bone) close to a major vessel (2.5 mm) and spine fractures. Visualizing fragments <5 mm from a vessel or a transcervical bullet trajectory predicted 12 of 13 major arterial injuries. We conclude that CT clearly depicts anatomic damage. Specific findings, such as the location of fragments and bullet trajectory adjacent to a vessel and spine fractures, indicate a higher probability of vascular damage, thus directing more definitive evaluation.     

Prevalence and localization of nodal metastases in squamous cell carcinoma of the oral cavity: role and extension of neck dissection

Lymph node (LN) metastases represent the most important negative prognostic factor in squamous cell carcinoma (SCC) of the oral cavity, even though controversies still exist regarding their management. The aim of this study was to retrospectively analyze our experience in surgical management of SCC of the oral cavity with particular focus on the prevalence and localization of lymph nodal metastases and recurrences. The clinical records of 89 consecutive patients treated from 1983 to 2002 by concomitant surgery on both the T and N sites, excluding those undergoing salvage surgery, were reviewed. A total of 119 neck dissections (ND) were performed. Survival outcomes were calculated by the Kaplan–Meier method, while univariate comparisons by the log-rank and non-parametric tests were performed between different groups of patients. Five-year overall and determinate survivals were 50 and 57%, respectively. LN metastases were observed in 52% (56% of these showing extracapsular spread) and their presence strongly correlated with determinate survival (p < 0.0001). The prevalence of clinical and occult nodal disease was not related to the pT status. Neck levels II (59%) and I (56%) were most frequently involved. Metastases to level IV accounted for 15% of positive LN, even though 28% of them turned out to be skip metastases. Five neck recurrences were observed, only one of which was salvaged by surgery. The high prevalence of clinical and occult LN metastases in this setting suggests that ND should be performed on a nearly routine basis, even for lesions with a low-T category and a cN0 neck. Moreover, ND should always encompass level IV due to the possibility of skip metastases, particularly in tumors involving the oral tongue. In patients with a cN+ neck, levels from I to V should be addressed, particularly in the presence of metastases at levels III and IV.     

Changes in UK ORL-HNS training scheme: Does the Indian trainee have a place anymore?

The determination of the UK Government to modernise medical careers, the shortage of training jobs for local medical graduates, the establishment of the Postgraduate Medical Training and Education Board (PMETB) and European Union rules have combined to change the scheme of surgical training in the United Kingdom. In the opinion of the author, the Indian Otorhinolaryngological (ORL) trainee can no longer aspire to reasonable higher training in the UK.     

Radioanatomy of upper airways in flexion and retroflexion of the neck

Summary Ten flexion-retroflexion radiographs of the cervical spine (in lateral projection) were utilized to study anatomical configuration and topography of the upper air passages in these two positions. Measurement of AP diameters revealed narrowing in flexion and widening in retroflexion, being maximat at the region of the epiglottis, and minimal at the regions of larynx and trachea. The distance from the pharyngeal attachment of the skull-base, to the upper chest aperture proved to be markedly greater in retroflexion than in flexion. As the pharynx virtually does not change its length during these movements, it is drawn up (with respect to the upper chest aperture) in retroflexion, and pushed down in flexion, over a mean distance of 42 mm. The up and down movement of the upper part of the trachea is slightly less: 38 mm. No correction for radiological magnification of 15–20%.
