Reconstruction of the hypopharynx after free jejunum flap failure: is a second free jejunum transfer feasible?

Reconstruction after circumferential pharyngolaryngectomy is a challenging problem. Reconstruction methods should ensure an appropriate mucosa lining of the digestive tract, preferably already tubulized, and peristalsis. Despite the high reported success rates, the jejunum flap is still occasionally lost due to thrombosis of the pedicle and/or fistula formation. Five cases of circumferential pharyngolaryngectomy in which failure of the jejunum loop was managed with a second free or pedicle flap are presented. A second free jejunum was reliable in selected patients, depending on time of detection of flap necrosis, on bacterial control of the wound and on the vascular or general conditions. For this reason, careful monitoring of the flap and clinical signs of necrosis in the first 5 post-operative days is crucial to prevent the formation of fistulas and infection and to increase the possibility of using this kind of salvage surgery. Pedicle flaps should be used only in the event of severe complications because of their high risk of post-operative salivary fistulas.

Sternocleidomastoid muscle flap in esophageal perforation repair after cervical spine surgery: concepts, techniques, and personal experience.

STUDY DESIGN: A retrospective report was conducted on clinical and instrumental data of 3 patients treated for esophageal perforation after anterior cervical spine surgery. OBJECTIVE: To define indications and evaluate the safety and effectiveness of surgical repair of esophageal perforations by means of sternocleidomastoid (SCM) muscle flap in the setting of anterior spinal surgery. SUMMARY OF BACKGROUND DATA: Esophageal perforation is an occasional or underreported complication in anterior cervical spine surgery. To prevent its potentially devastating and even life-threatening sequelae, prompt diagnosis and treatment are required. No treatment protocol has yet been standardized. In addition to conservative measures, several surgical approaches have been presented, ranging from primary repair to reconstruction with local, regional, or distant flaps. METHODS: Primary spinal pathology and intervention, esophageal fistulae morphology, diagnostic work-up, clinical course, and surgical techniques for their repair are illustrated in each case. Follow-up data have been gathered by in-person visits. RESULTS: Mean time from discovery of perforation to definitive surgical treatment institution was 44.3 days (range: 34 to 61 d). SCM muscle flap way used as reinforcement and protection of a primary esophageal suture in 2 cases and as a patch to the perforation in 1 case. All the fistulae healed without further complications. Mean time to oral feeding resumption was 17.6 days (range: 10 to 27 d) and mean hospitalization time was 19 days (range: 11 to 28 d). All the patients presented with a free oral diet at the last follow-up check. CONCLUSIONS: Esophageal perforation treatment has to be multidisciplinary and tailored on each individual case. SCM muscle flap, used as reinforcement of a primary suture or as a patch to the lesion, has proved to be effective as definitive treatment for persisting or recurring esophageal fistulae after anterior cervical spine surgery. In this setting, conservative treatments may be inadequate or may actually perpetuate the condition.

Curative and organ-preserving treatment with intra-arterial carboplatin induction followed by surgery and/or radiotherapy for advanced head and neck cancer: single-center five-year results.

BACKGROUND: This study evaluated the feasibility, toxicity, response rate and survival of neoadjuvant superselective intra-arterial infusion of high dose carboplatin in advanced head and neck cancer. METHODS: Forty-six patients with primary head and neck squamous cell carcinoma received 3 cycles of intra-arterial carboplatin (300 to 350 mg/m2 per cycle every 2 weeks), followed by radiotherapy or surgery plus radiotherapy. RESULTS: No complications or severe toxicity occurred. Sixteen patients (35%) were complete responders, 20 (43%) partial responders while 10 (22%) did not respond to treatment. After completion of the multimodality treatment, 38/46 patients (83%) were complete responders. After a 5-year follow-up period, 18/46 patients (39%) are alive and disease-free, 3 (6,5%) have died of a second primary tumor and 25 (54.5%) have died of the disease. CONCLUSION: Intra-arterial carboplatin induction chemotherapy is a safe, well-tolerated technique that discriminates between responders and non-responders and so may have prognostic significance in planning further integrated treatments aimed to organ preservation for advanced head and neck carcinomas.

Radiological Study of Maxillary Sinus using CBCT: Relationship between Mucosal Thickening and Common Anatomic Variants in Chronic Rhinosinusitis.

INTRODUCTION: Inflammatory diseases of the maxillary sinus favour the thickening of the sinus mucosa. Therefore, it might be possible to establish a radiological, pathological threshold of mucosal thickening. Furthermore, there is an association between common anatomic variants of the nose and maxillary mucosal thickening. AIM: To define the pathological thickening of maxillary sinus mucosa and its association with the presence of common anatomic variants (concha bullosa, Haller's cell and accessory maxillary ostium). MATERIALS AND METHODS: From March 2014 to February 2016, Two hundred patients underwent Cone Beam Computed Tomography (CBCT) of the paranasal sinus. We conducted this retrospective study of total 70 patients, 34 patients i.e., a total of 68 meatus-maxillary units (study group - those affected by Chronic Rhinosinusitis (CRS) and another 36 patients i.e., a total of 72 meatus maxillary units (control group - without symptoms of CRS). We assessed the degree of thickening of the sinus mucosa distinguishing between ≥ 2mm or ≤ 2mm, than we analysed the behaviour of the thickness in the study group and in the control group. Chi-Square test was used to compare mucosal thickening between study and control group and the presence of some common anatomic variants or closure of maxillary ostium. RESULTS: In the study group we observed a clear association between maxillary mucosal thickening ≥ 2mm and CRS (p<0.01). We however, observed no association between the presence of common anatomic variations and thickening of the maxillary mucosa and between the presence of common anatomic variations and the study group. Instead, using a binary logistic regression, we observed a significant association (p<0.01) between closure of natural ostium of the maxillary sinus and mucosal thickening or between closure of natural ostium and study group. CONCLUSION: We believe that a thickening of the maxillary mucosa ≥ 2mm and closure of natural maxillary ostium are statistically associated with CRS. The common anatomical variants do not seem to be associated with this condition.

Lingual metastasis from renal cell carcinoma: a case report and literature review.

Renal cell carcinoma (RCC) accounts for the 3% of all solid tumors. Despite continuous improvement in the therapy regimen, less has been achieved in terms of enabling an earlier diagnosis: the neoplasia usually reveals its presence at an advanced stage, obviously affecting prognosis. The most frequent sites of secondary disease are shown to be lungs (50-60%), bone (30-40%), liver (30-40%) and brain (5%); while the head and neck district seems to account for less than 1% of patients with primary kidney lesion. We report here the case of a 70-year old man who presented with acute renal failure due to abdominal recurrence of RCC 18 years post nephrectomy. After a few months of follow up without any systemic therapy due to the renal impairment, the patient presented a vascularized tongue lesion that was demonstrated to be a secondary localization of the RCC. This lesion has, therefore, been treated with microsphere embolization to stop the frequent bleeding and to lessen the unbearable concomitant symptoms it caused, such as dysphagia and pain. A tongue lesion that appears in a RCC patient should always be considered suspect and a multidisciplinary study should be conducted both to assess whether it is a metastasis or a primary new lesion and to understand which method should be selected, if necessary, to treat it (surgery, radiation or embolization). Lingual metastasis should be examined accurately not only because they seem to implicate a poor prognosis, but also because they carry a burden of symptoms that not only threatens patients' lives but also has a strong impact on their quality of life.

Atypical reconstructions with free jejunum flap after circumferential pharyngolaryngectomy.

The ideal reconstruction after circumferential pharyngolaryngectomy is represented by the jejunum free flap, but when the resection extends to the oro- or nasopharynx, the discrepancy between the lumen of the flap and the pharyngeal defect represents a disadvantage. Two reconstructions to overcome this problem are presented: end-to-side anastomosis between the pharynx and the antimesenteric side of the jejunum; and a jejunal "reservoir." The type 1 technique is quicker to perform, but can result in dysphagia; the type 2 technique is more complex, but usually no dysphagia is observed. In our opinion, no ideal surgical technique exists to equal the jejunum loop. The choice must be tailored to the single patient, bearing in mind the degree of the defect, the stage of the tumor removed, the general conditions of the patient, and personal surgical experience. Whatever procedure is chosen, it should provide the best possible quality of life for the expected life span of the patient.
