RESUMEN
During neck surgery; Zuckerkandl's tubercle, Berry's ligament, the inferior horn of thyroid cartilages have become crucial anatomical landmarks in order to protect the integrity of the recurrent laryngeal nerve. Forty-two male postmortem human cadavers were used. The proximal part of the recurrent laryngeal nerve, before the inferior thyroid artery arises from its source has been observed in 87% inside the tracheoesophageal groove and in 13% running laterally to the trachea. The recurrent laryngeal nerve was encountered passing behind and through the branches of the inferior thyroid artery in 92% and 8% respectively. At all sides; the nerve was piercing the larynx 0.6 ± 0.1 mm below the inferior horn of thyroid cartilage, passing next to the inner-lower side of Berry's ligament and running under the lower middle part of Zuckerkandl's tubercle. These landmarks and their upper mentioned distances to the laryngeal nerve can be taken into consideration as important surgical guides.
RESUMEN
A 44-years-old male presented with right infraauricular swelling. It had been four months since he was aware of the mass. He had not felt any pain or tenderness. Computed tomograpy demonstrated a homogenous, regular surfaced mass located in the prestyloid and poststyloid parapharyngeal space. Its density was concordant with lipomatous tissue, so it was considered to be an infiltrating parapharyngeal lipoma. Postoperative diagnosis revealed a similar result. We believe that computed tomograpy is an effective method of diagnosing parapharyngeal space tumors and tansparotid approach for this localization is very useful for both preserving facial nerve functions and exposing the mass clearly. We report a case of parapharyngeal lipoma slightly invading the deep lobe of the parotid gland.

Lipomas are one of the most frequently encountered benign tumors in any location. There is limited information about head and neck lipomas in the litetature and most data is in the form of case reports. Lipomas can rarely reach gigantic sizes and can invade surrounding tissues, especially skeletal muscles, and in this case they are called infiltrating lipomas. In this manuscript we report a case of cervical giant lipoma surrounding and infiltrating the common carotid artery which was treated by grafting carotid artery, and our diagnostic work-up and treatment procedure are discussed in the light of the literature.

Nasopharyngeal angiofibroma is a rare, benign vascular tumor originating from the sphenopalatine foramen. It primarily affects adolescent males. Due to its propensity to locally destructive growth, the tumor may lead to fatal epistaxis, intracranial extension, and life-threatening complications such as intraoperative hemorrhage. Many treatment modalities have been used for the management of nasopharyngeal angiofibroma, but surgery and external beam radiation therapy have proved to be the only effective treatment modalities with acceptable morbidity. While endoscopic surgery provides successful results for early stage tumors, recent technological advances in radiotherapy offer significant advantages in advanced and recurrent tumors.

Although benign tumors arising from the nasal cavity are common, those of the peripheral nerve sheath seen in this localization are unusual. We presented a 45-year-old woman with a nasal septal schwannoma filling the whole nasal cavity. She was treated successfully by transnasal endoscopic surgery. No recurrence was detected within a three-year follow-up period.

Although ameloblastoma is an odontogenic benign tumor, it shows a high local aggressive character resulting in significant morbidity and mortality. It is frequently seen in the mandible. Maxillary presentation shows a much more infiltrative character; such cases are seen in advanced disease forms with higher recurrence rates. It is reported that the tumor may spread to important anatomical structures such as the orbits and the pterygomaxillary fossa. In this report, we presented a case of maxillary ameloblastoma, which had been surgically treated in another health care unit by Caldwell-Luc and local curettage operations and recurred early in a wide anatomic area. The patient was treated successfully with a gingivobuccal excision and infratemporal fossa dissection with total maxillectomy.
