The aim of this study was to describe our experience with benign parapharyngeal space tumours resected via a transcervical route without mandibulotomy and to investigate associated postoperative sequelae and complications. The study investigated and analysed the retrospective charts of 44 patients who underwent surgery for benign parapharyngeal space tumours over a 10-year period. The diagnosis was reached in all patients with clinical and radiologic findings; preoperative fine-needle aspiration biopsy was not performed in any case. The preferred means of accessing the parapharyngeal space in all patients was a transcervical route. In 5 of these patients, transparotid extension was performed due to the position of the tumour. Tumours were classified radiologically as poststyloid in 27 cases and prestyloid in 17 cases. The final histopathologic diagnosis was vagal paraganglioma in 16 cases, pleomorphic adenoma in 13 cases, schwannoma in 10 cases and comparatively rarer tumours in the remaining 5 cases. In three patients, cranial nerve paralysis was observed during preoperative evaluation. Permanent cranial nerve paralysis occurred in 19 cases (43.2%) in the postoperative period, the majority of which were neurogenic tumours such as vagal paraganglioma (n = 16) and schwannoma (n = 2), and one case of non-neurogenic parapharyngeal tumour. The median duration of follow-up was 61 ± 33 months. There was no local recurrence in any patient during the follow-up period. A transcervical approach should be the first choice for excision of parapharyngeal space tumours, except for recurrent or malignant tumours, considering its advantages of providing direct access to the neoplasm, adequate control of neurovascular structures from the neck and optimal aesthetic outcomes due to preservation of mandibular continuity with minimal morbidity and hospitalisation time.

To determine flap success rate and complications in patients who underwent microvascular free tissue reconstruction after major head and neck ablative surgery and to report the improvement in the results. Medical records of 124 patients who were operated on in 2012 to 2019 were retrospectively reviewed. Indications for different free flap types, success rates and re-exploration rates, donor site morbidities, and reasons for flap loss were analyzed. Patients were divided into two groups to identify the effects of the anticoagulant and the antiaggregant treatments on postoperative results. There were 127 flaps in 124 patients, including two different free flaps each in three patients that were harvested and used in the same surgical session. Of the total 127 flaps, 82 (64.6%) were radial forearm flaps, 39 (30.7%) were fibula flaps, and 6 (4.7) were rectus abdominis flaps. Four patients were re-explored for flap perfusion problems, and 18 patients were re-explored for hematoma drainage (n=22/124, %17.3). The rate of hematoma and re-exploration was higher in patients who received anticoagulant and antiaggregant treatments synchronously (p=0.02). Three flaps were lost, and the overall success rate was 97.6%. Two patients died from perioperative complications. No major complications were observed at the donor site; minor complications were observed in 30 patients. The success rate for the 127 flaps in 124 patients were found comparable to those reported in the literature. These results show that successful outcomes can be achieved with experience and a head and neck team dedicated to improving the results in microsurgical reconstruction, and flap failure rarely occurs if perioperative care of the patients is given meticulously.

The aim of this study was to determine the frequency and the mechanism of submandibular gland (SMG) involvement in oral cavity squamous cell carcinomas (OCSCC), and to discuss the necessity of extirpation of the gland. The authors investigated and analyzed the retrospective charts of 236 patients who underwent surgery for OCSCC over a 10-year period and the pathology reports of 294 neck dissections with SMG removal. SMG involvement was evident in 13 cases (4%). Eight cases were due to direct invasion, which was the most common mechanism. Four cases had infiltration from a metastatic periglandular lymphadenopathy, and in 1 case, metastatic disease was confirmed. The tongue and floor of the mouth were the most frequent primary sites associated with SMG involvement. The study found no bilateral cases, and in 135 SMG specimens benign pathologies were detected. Involvement of the SMG in OCSCC is not frequent. It is appropriate to preserve the gland unless the primary tumour or metastatic regional lymphadenopathy is adherent to the gland.
