In this chapter, we examine the chronic inflammatory diseases of the nasal cavity and paranasal sinuses. First, we examine the basic characteristics of the various chronic inflammatory diseases of the nasal cavity and paranasal sinuses and chronic inflammatory diseases of the oral cavity. Further, we discuss the etiopathogenesis, diagnosis, differential diagnosis, and treatment options for the ...

BACKGROUND Facial node involvement in head and neck cancer is rarely documented. Furthermore, facial node removal may increase the risk of damage to the marginal mandibular nerve. Thus, although they may receive afferent lymphatic drainage from the oral cavity, facial nodes are rarely removed during neck dissection. METHODS We retrospectively reviewed the records of 29 patients with oral cavi...

BACKGROUND The association between nodal ratio and survival in oral cavity carcinomas has recently been proposed, but no prospective evaluations exist. METHODS We sought to determine, using an institutional database, whether nodal ratio impacts survival in node-positive oral cavity squamous cell carcinoma. RESULTS Between 1994 and 2004, 143 new diagnoses of N(1-2) squamous cell carcinoma of...

The oral cavity is the most predominant location in the head and neck region for primary malignant tumors, and more than 90 % cancer consists of squamous cell carcinoma (SCC).(Shah and Patel 2003) SCC has a high propensity to early and extensive lymph node metastases. Regarding cancer stage distribution at diagnosis, regional spread is more frequent in cancers of oral cavity and pharynx compare...

A varied spectrum of lesions ranging from developmental, reactive, inflammatory to neoplastic manifests in the oral cavity ,as oral mucosa is constantly subjected to varied stimuli. These lesions may be either generalized or localized. Most of the localized oral overgrowths are considered to be reactive rather than neoplastic in nature. The reactive lesions of oral cavity are associated with in...

objective: the aim of the present study was to estimate crude and age-standardized incidence rates for oral and pharyngeal nonsquamous cell malignant tumors in kerman province over a period of 11 years. materials and methods: the data used in this retrospective population-based study were extracted from the records registered in all pathology centers of kerman province from 1991 to 2001. all co...

squamous cell carcinoma (scc) is the most common malignant tumor of the oral cavity and one of the ten most common causes of death. it arises from dysplastic oral squamous epithelium. considering the pathogenesis of scc, a smooth and intact surface in this lesion is not a usual finding. in this paper, we report an extremely rare case of oral scc in buccal mucosa presenting as an exophytic lesio...

oral mucosa can be affected in many systemic diseases such as chronic renal failure (crf). many metabolic and hematologic disorders develop in patients with crf which can also affect oral cavity. oral mucosa, teeth, salivary glands and jaw bones are affected. although hemodialysis can improve many of systemic features but the best treatment is renal transplantation. in addition to previous feat...

BACKGROUND Various surgical options are available for reconstruction of intraoral soft tissue defects. For smaller defects of the oral mucosa in different anatomic locations of the oral cavity the nasolabial flap is a very useful and simple alternative to other pedicled flaps and free flaps. METHODS The results of reconstruction of oral mucosal defects or facial skin defects using 29 nasolabi...

BACKGROUND Human papillomavirus (HPV), the causal agent of cervical cancer, appears to be involved in the etiology of cancer of the oral cavity and oropharynx. To investigate these associations, we conducted a multicenter case-control study of cancer of the oral cavity and oropharynx in nine countries. METHODS We recruited 1670 case patients (1415 with cancer of the oral cavity and 255 with c...
